1. *Much* more infor please.
2. GWIA doesn't send bounces. Do you have a relay host in front of GWIA?
If yes, *that* is the offender.

Then it's (of course I have to say) Mailsweepers fault.

If the user isn't known in GWIA, Mailsweeper will not be able to pass it
to GWIA at all. GWIA denies it, and is doen with it. If that results in
a bounce to the original sender, then Mailsweeper is either
misconfigured or crap, or both.

Nobody. GWIA knows that users don't exist, it never even accepts the
mail, and it never gets anywhere. Your problem is that Mailsweeper
doesn't know the list of valid users, so it blindly accepts anything
sent to your mail. How or if Mailsweeper can be made aware of your users
is something I don't know. But it's the only proper solution. Your
*first* entry point for emails must essentially be able to determine if
a receipient exists or not. If it can't do that, that product isn't fit
for real world use.

You're still barking up the to completely wrong tree. There is nothing
you can do in Groupwise to "fix" anything, as there is absolutely
nothing wrong there. DSN has absolutely nothing to with this.

No different one than the last time. Your problem is Mailsweeper, not
Groupwise. You cannot do anything in Groupwise to change that.

Please start a new thread, as your problem doesn't have any connection
to this topic here. And when you do, please provide some detail,
otherwise it's impossible to help. For instance, the real domain name
you're sending to, and the error message they receive when they try to
send to you.
