OtherHeaders Property

An RFC 822 compliant string consisting of extra headers.

Syntax

 smtp.getOtherHeaders([callback])
 smtp.setOtherHeaders( otherHeaders, [callback])

Default Value

""

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for the getOtherHeaders([callback]) method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

The callback for the setOtherHeaders([callback]) method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This property contains a string of headers to be appended to the message headers created from other properties like SendTo, Subject, etc.

The headers must of the format "header: value" as specified in RFC 822. Header lines should be separated by CRLF ("\r\ n") .

Use this property with caution. If this property contains invalid headers, message delivery might not be successful.

This property is useful for extending the functionality of the class. A good example is delivery of MIME encoded messages.

SPECIAL CASE: if this property starts with an empty line (CRLF), then the value of this property is used instead of the normally computed message headers.

Example (Send an Email With Additional Header)

control.MailServer = "MyServer"
control.From = "me@server.com"
control.SendTo = "recipient@server.com"
control.Subject = "My Subject"
control.MessageText = "This is the message body"
control.OtherHeaders = "HeaderName: Headervalue"
control.Send()

This property is not available at design time.
