OK, so the message is arriving via the "mailnull" user, using the "spam-scanned"
protocol, for "info@???". You then deliver it to two
destinations: the "barbara" virtual_localuser and also to
"bachelander@???". But that msn address bounces.

Next thing for you to do is double-check that msn address - fix it if it's
wrong, remove it if it's not needed.

If you suspect that maybe you've got more of these bogus forwarding rules to
find and check, you might want to

    fgrep '**' mainlog | cut -d' ' -f5,6


to find the addresses that are bouncing.
