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

Nov 15 13:18:39 ns courierd: started,id=00004229.3FADA6FF.00007FB1,from=<>,module=esmtp,host=sweepingminesweeper.com,addr=<Para@sweepingminesweeper.com> Nov 15 13:18:40 ns courieresmtp: id=00004229.3FADA6FF.00007FB1,from=<>,addr=<Para@sweepingminesweeper.com>:
Connection refused Nov 15 13:18:40 ns courieresmtp: id=00004229.3FADA6FF.00007FB1,from=<>,addr=<Para@sweepingminesweeper.com>,status:

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.
