Return-Path Email Header Problems

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying to change the "Return-Path" in an email that my server will be sending out. However, doing the following does not work. (Note: this code _does_ work properly, aside from setting the Return-Path.)

$header = "Return-Path: $from\r\nFrom: $from\r\nTo: $recipient\r\nRepl
+y-To: $from\r\nSubject: Subject Here";

open (MAIL, "|$mailprog $recipient");
print MAIL $header."\n\n";

This email is being read by another script, and it reads the Return-Path. Thus, the need to forge this header ;) Thanks.

As fastolfe said, it depends on your `$mailprog`. If you are using `mail` or `mailx`, you are out of luck. If you are using `sendmail` or `qmail-inject`, include the `-f sender` argument. Also see the on-line manual for your mail program, whatever it is.	[reply]

The "Return-Path" is normally added by the MTA to match the envelope sender, so with many mailers it's significantly more difficult to forge. Unfortunately we'd need more information (such as the $mailprog and/or MTA) in order to help you.	[reply]

`$mailprog="/usr/sbin/sendmail -t";` [download] Sorry I didn't deem this important to begin with.	[reply] [d/l]
