Use ChilkatAx-win32.pkg
Procedure Test
Boolean iSuccess
Handle hoEmail
Handle hoXml
String sXmlStr
Boolean iBHeaderOnly
String sHumanReadableExplanation
Variant vMdnEmail
Handle hoMdnEmail
String sTemp1
Move False To iSuccess
Get Create (RefClass(cComChilkatEmail)) To hoEmail
If (Not(IsComObjectCreated(hoEmail))) Begin
Send CreateComObject of hoEmail
End
// An MDN can be used to notify the
// sender of a message of any of several conditions that may occur after
// successful delivery, such as display of the message contents,
// printing of the message, deletion (without display) of the message,
// or the recipient's refusal to provide MDNs.
// (for more information, see RFC 3798)
// IMPORTANT:
// Note: Please be careful in sending automated MDN's.
// It is important to be aware of an issue called "backscatter".
// See the Wikipedia article here: http://en.wikipedia.org/wiki/Backscatter_%28e-mail%29
// The ToMdn method is called to create a new
// MDN email based upon the email object calling ToMdn.
// The email object instance used to call ToMdn would
// typically be an email received from a POP3 or IMAP server.
// In this case, to simplify the example, we'll load the email
// from a .eml file.
// This example will be creating a MDN for "someEmail.eml"
Get ComLoadEml Of hoEmail "someEmail.eml" To iSuccess
If (iSuccess = False) Begin
Get ComLastErrorText Of hoEmail To sTemp1
Showln sTemp1
Procedure_Return
End
// The MDN created by ToMdn will contain a
// "message/disposition-notification" MIME sub-part that will
// be composed of a number of name-value pairs.
// See RFC 3798 ( http://tools.ietf.org/html/rfc3798 )
// The name-value content for this part is passed
// as XML to ToMdn. This part of the example
// prepares the XML:
Get Create (RefClass(cComChilkatXml)) To hoXml
If (Not(IsComObjectCreated(hoXml))) Begin
Send CreateComObject of hoXml
End
// For this example, we're just adding a few name-value pairs.
// These should not be considered to be correct, required or
// even sensible -- they are simply for the example.
Set ComTag Of hoXml To "DispositionFields"
Send ComNewChild2 To hoXml "Disposition" "manual-action/MDN-sent-manually; displayed"
Get ComGetHeaderField Of hoEmail "Message-ID" To sTemp1
Send ComNewChild2 To hoXml "Original-Message-ID" sTemp1
Get ComGetToAddr Of hoEmail 0 To sTemp1
Send ComNewChild2 To hoXml "Final-Recipient" sTemp1
Get ComGetXml Of hoXml To sXmlStr
// The last argument to be passed to ToMdn will be a boolean
// indicating whether to include the entire MIME of the calling
// email object in the MDN, or only the header.
// It may make sense to include the entire email for small emails,
// but for large emails (with large attachments) it's probably
// best to make the MDN header-only.
Move True To iBHeaderOnly
// The first argument to be passed to ToMdn will
// be a human-readable explanation that will be placed
// into the 1st MIME part of the MDN (see RFC 3798).
Move "Blah blah blah. Your message has been received and displayed. Blah blah blah" To sHumanReadableExplanation
// OK, we're ready to create MDN...
Get Create (RefClass(cComChilkatEmail)) To hoMdnEmail
If (Not(IsComObjectCreated(hoMdnEmail))) Begin
Send CreateComObject of hoMdnEmail
End
Get pvComObject of hoMdnEmail to vMdnEmail
