Currently, I'm using MIME::Lite, which let's you do something like this:

my $sender = 'yourname@example.com';
my $msg = MIME::Lite->new(
        Type       => 'TEXT',
        From       => $sender, 
        To         => 'theirname@example.com',
        Subject    => 'Simple Greeting'
        ReplyTo    => $sender,
        ErrorsTo   => $sender,
        Data       => 'Greetings, Lifeform!'
     );

$msg->send_by_smtp( 'localhost' )
   or die "Unable to send message; reason $!\n";

Note: the above is off the top of my head, so there may be typos or other silly mistakes. If so, sorry.

The interesting bit, I think, in the above is the ErrorsTo line. That seems to work, provided you take care to send it to an appropriate address. For example, I have a special mailbox devoted to those errors.

MIME::Lite also offers several alternatives for sending. For details, check the docs.

Hope this helps...

--f

-f sender

Well, the "return path" is not a header field. It's more officially called the "envelope from", or "From_". And -f does in fact set it, if you're permitted by the configuration.

Of course, with SMTP as your first hop rather than sendmail, to some degree you have much more flexibility, including setting envelope from/to independent of the header from/to and sender.
