IMAP Control
Properties Methods Events Config Settings Errors
The IMAP Control is used to communicate with IMAP servers using the Internet Message Access Protocol (IMAP).
Syntax
IMAP
Remarks
The IMAP Control supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections (RFC 2595). When connecting over SSL/TLS the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the SSL handshake. Additional SSL related settings are also supported via the Config method.
The IMAP Control implements a standard IMAP client as specified in RFC 1730 and RFC 2060.
The first step in using the control is specifying a MailServer, a User to connect as, and a Password to authenticate with. After that, one or more requests may be sent to the server via the control's methods. Results are retrieved through events and a number of key properties.
Normally, after connecting to the server, a Mailbox is selected (or examined) using the ExamineMailbox method. After the Mailbox is selected, MessageCount and RecentMessageCount show the number of messages in the mailbox, and MailboxFlags show the flags pertaining to the mailbox.
A number of operations may be performed by the server in response to commands sent using the control's methods. The primary arguments for most commands are the Mailbox property and the MessageSet property. The MessageSet property denotes either a single message, or a range of messages. Other arguments are specified through other properties, such as SortCriteria and MessageFlags.
Responses are received through events, such as MessageInfo and MailboxList, and also are reflected to properties, such as MessageText and MessageSubject.
The MessagePart event describes the MIME structure of the retrieved messages. One MessagePart event is fired for every message part, giving information about the particular part. Later on, message parts may be retrieved separately through the FetchMessagePart method. This speeds up processing by avoiding the need to retrieve full messages from the server.
The PITrail event traces the interaction between the client and the server. It includes all exchanges except for transfers of messages, message parts, and message headers.

Default Value
""
Remarks
This is the subject of the certificate used for client authentication.
This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.
If a matching certificate is found, the property is set to the full subject of the matching certificate.
If an exact match is not found, the store is searched for subjects containing the value of the property.
If a match is still not found, the property is set to an empty string, and no certificate is selected.
The special value "*" picks a random certificate in the certificate store.
The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:
Field | Meaning |
CN | Common Name. This is commonly a hostname like www.server.com. |
O | Organization |

L | Locality |
S | State |
C | Country |
E | Email Address |
If a field value contains a comma, it must be quoted.
Data Type
String
SSLProvider Property (IMAP Control)
This specifies the SSL/TLS implementation to use.
Syntax
imapcontrol.SSLProvider[=integer]
Possible Values
sslpAutomatic(0), sslpPlatform(1), sslpInternal(2)
Default Value
0
Remarks
This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the control will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.
Possible values are:
0 (sslpAutomatic - default) | Automatically selects the appropriate implementation. |
1 (sslpPlatform) | Uses the platform/system implementation. |
2 (sslpInternal) | Uses the internal implementation. |
In most cases using the default value (Automatic) is recommended. The control will select a provider depending on the current platform.
When Automatic is selected the platform implementation is used by default. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used.
Data Type
Integer
SSLServerCertEncoded Property (IMAP Control)
This is the certificate (PEM/base64 encoded).
Syntax
imapcontrol.SSLServerCertEncoded
Default Value
""
Remarks
This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The SSLServerCertStore and SSLServerCertSubject properties also may be used to specify a certificate.
When SSLServerCertEncoded is set, a search is initiated in the current SSLServerCertStore for the private key of the certificate. If the key is found, SSLServerCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLServerCertSubject is set to an empty string.
To read or write binary data to the property, a Variant (Byte Array) version is provided in .SSLServerCertEncodedB.
This property is read-only and not available at design time.

Possible Values
sslAutomatic(0), sslImplicit(1), sslExplicit(2)
Default Value
0
Remarks
The SSLStartMode property may have one of the following values:
0 (sslAutomatic) | If the remote port is set to the standard plaintext port of the protocol (where applicable), the control will behave the same as if SSLStartMode is set to sslExplicit. In all other cases, SSL negotiation will be implicit (sslImplicit). |
1 (sslImplicit) | The SSL negotiation will start immediately after the connection is established. |
2 (sslExplicit) | The control will first connect in plaintext, and then explicitly start SSL negotiation through a protocol command such as STARTTLS. |
Data Type
Integer
StartByte Property (IMAP Control)
This property includes the byte index of the position where the transfer should start.
Syntax
imapcontrol.StartByte[=long64]
Default Value
0
Remarks
StartByte and EndByte are used together with the FetchMessagePart method to specify the portion of the message to be retrieved from the server.
When StartByte or EndByte contain values other than the default (0), only the corresponding portion of the message is retrieved from the server.
Byte indexes start from 1. The default value for EndByte is 0, which corresponds to the end of the message.
This property is not available at design time.
Data Type
Long64
Timeout Property (IMAP Control)
A timeout for the control.
Syntax
imapcontrol.Timeout[=integer]
Default Value
60
Remarks
If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.
If Timeout is set to a positive value, the control will wait for the operation to complete before returning control.
The control will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.
If Timeout expires, and the operation is not yet complete, the control fails with an error.
Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.
The default value for the Timeout property is 60 seconds.
Data Type
Integer
UIDMode Property (IMAP Control)
If True, this property indicates whether permanent message identifiers are used instead of the default temporary identifiers.
Syntax
imapcontrol.UIDMode[=boolean]
Default Value
False
Remarks
This property indicates if a permanent identifier should be used. Normally, the IMAP server uses temporary message identifiers that are valid only during the current session. If UIDMode is True, permanent message identifiers are used instead.
The following IMAP protocol operations use the UID mode: COPY, FETCH, STORE, and SEARCH.
This property is not available at design time.
Data Type
Boolean
UIDValidity Property (IMAP Control)
This property includes the UIDValidity parameter sent from the server in response to SelectMailbox command.
Syntax
imapcontrol.UIDValidity
Default Value
""
Remarks
Every time a mailbox is selected, a UIDValidity is returned from the server. Most of the time, this value will not change from call to call. If it does change, this means that all previously returned UIDs for messages inside this mailbox are now invalid.
This property is read-only and not available at design time.
Data Type
String
User Property (IMAP Control)
This property includes the username used to authenticate to the MailServer .
Syntax

Sub imapcontrol_MessagePart(PartId As String, Size As Long64, ContentType As String, Filename As String, ContentEncoding As String, Parameters As String, MultipartMode As String, ContentId As String, ContentDisposition As String)
Remarks
The PartId parameter denotes the PartId that may be identified in other parts or messages. The format of PartIds is specified by the IMAP RFCs.
The Size parameter gives the size of this part.
The ContentType parameter shows the type of data contained in the part.
The ContentEncoding parameter shows how data are encoded.
The Filename parameter shows the filename corresponding to the part (if the part was included in the message as an attached file).
The Parameters parameter contains the additional parameters passed to the ContentType header, such as the part charset.
The MultipartMode parameter shows the how this part relates to the message's whole multipart structure (e.g., 'mixed', 'alternative', etc.).
The ContentId parameter shows the value of the Content-Id header for the part.
The ContentDisposition parameter shows the value of the Content-Disposition header for the part.
PITrail Event (IMAP Control)
This event traces the commands sent to the mail server, and the respective replies.
Syntax
Sub imapcontrol_PITrail(Direction As Integer, Message As String)
Remarks
The PITrail event is useful for debugging and learning purposes. It shows all of the interactions between the client and the server, line by line, except for message header and body transfers.
The Message parameter contains the full text of the message. The Direction parameter shows the originator of the message:
0 (Client) | The Message originates from the client. |
1 (Server) | The Message originates from the server. |
2 (Information) | The Message is an informative message originating from the client software (the control code). |
SSLServerAuthentication Event (IMAP Control)
Fired after the server presents its certificate to the client.
Syntax
Sub imapcontrol_SSLServerAuthentication(CertEncoded As String, CertSubject As String, CertIssuer As String, Status As String, Accept As Boolean)
Remarks
During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.
When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.
SSLStatus Event (IMAP Control)
Shows the progress of the secure connection.
Syntax
Sub imapcontrol_SSLStatus(Message As String)
Remarks
The event is fired for informational and logging purposes only. This event tracks the progress of the connection.
StartTransfer Event (IMAP Control)
This event is fired when the message body or the part data start transferring.
Syntax
Sub imapcontrol_StartTransfer(Direction As Integer)
Remarks
The StartTransfer event is fired when the message body or the part data start transferring from the server to the local host. Further progress information is provided by the Transfer and EndTransfer events.
The Direction parameter shows whether the client (0) or the server (1) is sending the data.
Transfer Event (IMAP Control)
This event is fired while the message is transferred from the MailServer .
Syntax
Sub imapcontrol_Transfer(Direction As Integer, BytesTransferred As Long64, PercentDone As Integer, Text As String)
Remarks
The Transfer event is fired for every incoming line when receiving a message or part data from the MailServer
The Text parameter contains the portion of the message or the part data being retrieved.
The BytesTransferred parameter contains the number of bytes transferred since the beginning of the message, including header bytes. At the end of transmission (i.e., when the last Transfer event is fired), BytesTransferred equals the value of the MessageSize property.
The Transfer event is fired for every line of the message. There is no terminating newline at the end of the Text parameter. A faster way to retrieve a message is to assign a value to the LocalFile property and use the Transfer event to check the progress only rather than to get the actual data.
The Direction parameter shows whether the client (0) or the server (1) is sending the data.
The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.
Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.
Config Settings (IMAP Control)
The control accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, access to these internal properties is provided through the Config method.
IMAP Config Settings
The default value for this setting is False.
The date-time should be formatted according to the IMAP RFC specifications. For example, "22-Jan-2013 12:34:56 -0500" indicates January 22nd, 2013, at 12:34:56 PM EST.
By default, if this setting is not specified, no date-time is sent with the APPEND request, and the server will use the current time.
Bearer ya29.AHES6ZRmS-8xPbpGetC1VbABJIBRdKm-c4X7wMVGAbgxdGt5q8Ts3Q
Note: When using amXOAUTH2, User must be specified, but Password is not required.
This configuration setting specifies whether the control will use the IMAP4 Id extension defined in RFC 2971 and send the Id command to the server. When set to , the control will send the Id command with the value IPWorksIMAP if the server supports this as defined in the server's response to the CAPABILITY command.
The default value is , and this command will not be sent.
TCPClient Config Settings
If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.
Note: This setting is provided for use by controls that do not directly expose Firewall properties.

0 | No firewall (default setting). |
1 | Connect through a tunneling proxy. FirewallPort is set to 80. |
2 | Connect through a SOCKS4 Proxy. FirewallPort is set to 1080. |
3 | Connect through a SOCKS5 Proxy. FirewallPort is set to 1080. |
10 | Connect through a SOCKS4A Proxy. FirewallPort is set to 1080. |
Note: This setting is provided for use by controls that do not directly expose Firewall properties.

Note: This value is not applicable in macOS.
In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.
In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.
The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the control returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).
Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.
In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the control initiate connections (or accept in the case of server controls) only through that interface.
If the control is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).
Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.
LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.
This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.
If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.
If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.
The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

Note: This value is not applicable in Java.
By default, this config is set to false.
0 | IPv4 Only |
1 | IPv6 Only |
2 | IPv6 with IPv4 fallback |
SSL Config Settings
When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.
Enabling this setting has no effect if SSLProvider is set to Platform.
The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g. 9d66eef0.0, 9d66eef0.1 etc). OpenSSL recommends to use the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.
The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by
-----BEGIN CERTIFICATE-----
... (CA certificate in base64 encoding) ...
-----END CERTIFICATE-----
sequences. Before, between, and after the certificates text is allowed which can be used e.g. for descriptions of the certificates. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.
The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".
By default OpenSSL uses the device file "/dev/urandom" to seed the PRNG and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.
If set to true, the control will reuse the context if and only if the following criteria are met:
- The target host name is the same.
- The system cache entry has not expired (default timeout is 10 hours).
- The application process that calls the function is the same.
- The logon session is the same.
- The instance of the control is the same.

When set to 0 (default) the CRL check will not be performed by the control. When set to 1, it will attempt to perform the CRL check, but will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported.
This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.
When set to 0 (default) the control will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported.
This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.
Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.
Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.
When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList config setting.
By default, the enabled cipher suites will include all available ciphers ("*").
The special value "*" means that the control will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.
Multiple cipher suites are separated by semicolons.
Example values when SSLProvider is set to Platform:
obj.config("SSLEnabledCipherSuites=*");

When TLS 1.3 is negotiated (see SSLEnabledProtocols) only the following cipher suites are supported:
- TLS_AES_256_GCM_SHA384
- TLS_CHACHA20_POLY1305_SHA256
- TLS_AES_128_GCM_SHA256
SSLEnabledCipherSuites is used together with SSLCipherStrength.
Not all supported protocols are enabled by default (the value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:
TLS1.3 | 12288 (Hex 3000) |
TLS1.2 | 3072 (Hex C00) (Default) |
TLS1.1 | 768 (Hex 300) (Default) |
TLS1 | 192 (Hex C0) (Default) |
SSL3 | 48 (Hex 30) [Platform Only] |
SSL2 | 12 (Hex 0C) [Platform Only] |
SSLEnabledProtocols - TLS 1.3 Notes
By default when TLS 1.3 is enabled the control will use the internal TLS implementation when the SSLProvider is set to Automatic for all editions.
In editions which are designed to run on Windows SSLProvider can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is only supported on Windows 11 / Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version.
If set to 1 (Platform provider) please be aware of the following notes:
- The platform provider is only available on Windows 11 / Windows Server 2022 and up.
- SSLEnabledCipherSuites and other similar SSL configuration settings are not supported.
- If SSLEnabledProtocols includes both TLS 1.3 and TLS 1.2 the above restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions.
SSLEnabledProtocols: SSL2 and SSL3 Notes:
SSL 2.0 and 3.0 are not supported by the control when the SSLProvider is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and SSLProvider needs to be set to platform.
This setting is only applicable when SSLProvider is set to Internal.
If set to True all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.
When set, the control will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffice for debugging purposes. When writing to this file the control will only append, it will not overwrite previous values.
Note: This setting is only applicable when SSLProvider is set to Internal.

The value of this setting is a newline (CrLf) separated list of certificates. For instance:
-----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp .. d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE-----
When specified the control will verify that the server certificate signature algorithm is among the values specified in this setting. If the server certificate signature algorithm is unsupported the control fails with an error.
The format of this value is a comma separated list of hash-signature combinations. For instance:
component.SSLProvider = TCPClientSSLProviders.sslpInternal;
component.Config("SSLEnabledProtocols=3072"); //TLS 1.2
component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa");
The default value for this setting is sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa.
In order to not restrict the server's certificate signature algorithm, specify an empty string as the value for this setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.
The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.
When using TLS 1.2 and SSLProvider is set to Internal, the values refer to the supported groups for ECC. The following values are supported:
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1" (default)
The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result only some groups are included by default in this setting.
Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used which is not present in this list it will incur an additional round trip and time to generate the key share for that group.
In most cases this setting does not need to be modified. This should only be modified if there is a specific reason to do so.
The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072
The values are ordered from most preferred to least preferred. The following values are supported:
