What you are looking for is a fundamental part of SMTP. You need to set
the SMTP *envelope From* (which is not necessarily the same as the message
body "From:" header). So, for example, if I have a conversation like this
where the remote MTA rejects the message, the bounce would go to
<bounce@???>:
HELO my.hostname
MAIL FROM: <bounce@???>
RCPT TO: <someone@???>
DATA
...
From: <me@???>
...
However, it's generally not trivial to set this from a sending MUA. If
whatever MUA you are using is on something *ix-ish and has an option to
pass the mails to a command line tool instead of sending them out via
SMTP, you may be able to set the envelope sender using, for example
"sendmail -f blah". However, this won't help if you're just using Outlook
or something.
If you're really talking about a signficant number of addresses, however,
you should perhaps consider looking into some kind of mailing list
management software which may make things easier for you in this and other
respects.
