What you get in the "From " line is the enveloppe-from (ie the argument to the SMTP MAIL command) not an IP. And in the case of spam, it is most likely fake too. Usually, the Return-Path contains the exact same information, since it is often added or replaced by the last MTA or the MDA. > If I were able to log onto my ISP's servers, the initial "From" line in the > Berkeley mail format, I am told by my ISP admins, holds valid information, > but IMAP doesn't return this "From" line as part of a message as it is, > technically, > considered envelope information.

The "From " line is not a header, it is used as a separator in the mail box file. Your IMAP server is rightfully ignoring it since it is not part of the mail.

Since it is not a rfc822 header, and IMAP only deals with rfc822 messages, clients expect to receive rfc822 messages, so including the "From " line would break the protocol. If the Return-Path is really different that the "From " line on your case, you might ask your ISP to stick the "From " line as an header in the received mails. The unofficial X-From_ header is sometimes used for that. Gaël. -- Gaël Roualland -+- [EMAIL PROTECTED]
