Please help!

I am running a joke mailing list consisting of about 700 people,
the problem I am experiencing is that should one of the deliveries
fail, the error message is being sent back to the list.

I will try an explain a little about how I have it all set up, and hopefully
someone will be able to spot where I'm going wrong.

When someone e-mails a joke to joke-list@???, it hits an alias...
> joke-list:              jokelist


jokelist is a valid local user. In jokelist's home directory I have a filter file
(.forward) that looks a little like this...

> # Filter out any returned error messages.
> if $header_to is "jokelist@???" or

If anything get's e-mailed directly to jokelist, it get's junked. If anyone
e-mails anything with subscribe or unsubscribe to the list, it gets
redirected to listmaster.

Should all be well, the e-mail get's piped to a shell script that mangles the
header and fires off sendmail to deliver it.

Now, this seems to work absolutly fine, appart from one thing, the Return-Path and Sender headers all point back to jokelist@??? and there is no
visible way to change this.

Am I just being stupid?
