Do you use -dashext emails, like setiadi-qmail@example.com?  Make sure
your spam filter understands that those are allowed.  I frequently make
up email addresses like those on the fly so I can see if an online
registration has sold my address to someone.

A more permanent solution might be to see if your spam filter can query
an LDAP server for proper email addresses.  Or are you doing this so
that you can tell your Barracuda "this IP address tried to send to a
bogus email account -- put them on an RBL"?
