Hi,
recently courier at my server logged these weird lines (several times):

I would like to know what is actually happening - is the server trying
to send mail to the sweepingminesweeper.com address?
Yes, a bounce, precisely.
If yes, how could
this message come to my server - all smtp users have to authenticate
with login and password. ;(
Someone's mail filter rejected a message, and this is the bounce going back
to the sender. Look at the previous lines in the maillog, they should
log a local bounce.
