SIMAP Class

Properties   Methods   Events   Config Settings   Errors  

The SIMAP Class is used to communicate with IMAP servers using the Internet Message Access Protocol (IMAP).

Syntax

ipworkssmime.SIMAP

Remarks

The SIMAP Class is the S/MIME-enabled equivalent of the IPWorks IMAP class. In addition to standard IMAP functions, the SIMAP class can decrypt or verify message signatures. The methods and properties for decrypting, and verifying signatures are identical to those provided with the S/MIME Class. When attempting to verify a signed message or when decrypting a message, call the Decrypt, VerifySignature, or DecryptAndVerifySignature methods, and the resulting text will be replaced in Message.

The SIMAP Class implements a standard IMAP client as specified in RFC 1730 and RFC 2060.

The first step in using the class 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 class'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 class'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 RetrieveMessagePart 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.

Remarks

This property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.

If the class is connected, the LocalHost property 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 multihomed hosts (machines with more than one IP interface).

Default Value

0

Remarks

StartByte and EndByte are used together with the RetrieveMessagePart 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.

Timeout Property (SIMAP Class)

The timeout for the class.

Syntax

public int getTimeout();
public void setTimeout(int timeout);

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 class will wait for the operation to complete before returning control.

The class 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 class throws an exception.

Note: By default, all timeouts are inactivity timeouts, that is, 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.

UIDMode Property (SIMAP Class)

If True, this property indicates whether permanent message identifiers are used instead of the default temporary identifiers.

Syntax

public boolean isUIDMode();
public void setUIDMode(boolean UIDMode);

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.

UIDValidity Property (SIMAP Class)

This property includes the UIDValidity parameter sent from the server in response to SelectMailbox command.

Syntax

public String getUIDValidity();

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.

User Property (SIMAP Class)

This property includes the username used to authenticate to the MailServer .

Syntax

public String getUser();
public void setUser(String user);

  ...
}

public class SIMAPTransferEvent {
  public int direction;
  public long bytesTransferred;
  public int percentDone;
  public String text;
}

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.
