Description

The SMTP_Comments command lets the user add text comments to the message while keeping the message's body untouched. The comments only appear within the header section of the message. Many mail readers do not display the full text of the message header to their users.

smtp_ID is the long integer reference to the mail message created with the SMTP_New command.

comments is a text value containing information you would like placed in the mail header.

Warning: The text should not contain a line feed (ascii=10). Doing so would signify the end of the header section and the beginning of the body. Subsequent header items could be pushed into the body and not recognized properly by the server or client software. For more information regarding the headers, please refer to RFC#822.

deleteOption is an integer value which specifies whether to replace or delete the "Comments" header:

A value of zero will set the "Comments" field to the new value, overriding any prior settings (if you pass an empty string in comments, the prior header will be kept).
A value of 1 will set the "Comments" field to the new value, overriding any prior settings (if you pass an empty string in comments, the header will be deleted).
A value of 2 will delete any comments previously defined for the "Comments" field and remove the header from the mail envelope.
deleteOption is an optional parameter which will default to zero if not otherwise specified.
