Setting a 'Return-Path' header won't actually achieve anything, because it
will be instantly stripped off by the MTA. Only the final, delivering MTA is
allowed to add a Return-Path header to the message.

What you want is to set the envelope sender, MAIL FROM:<...>, and this is
done using the -f option to sendmail: i.e.
     sendmail [EMAIL PROTECTED] [EMAIL PROTECTED]

sendit.sh does this already. I would guess your problem is that your MTA
doesn't "trust" the Unix user which sqwebmail is running as, and therefore
ignores the -f option. If your mails have a return path of
"[EMAIL PROTECTED]" (and your webserver is running as user 'nobody')
then that's a strong indication.

How to fix this depends on your MTA. Sendmail would use the 'T' class, exim
has 'trusted_users' or 'trusted_groups'; others on this list can tell you
how to configure courier-MTA.
