My Postfix log is full of repeated connections and disconnections from the same machine:
Feb 26 11:43:41 rafa postfix/submission/smtpd[13829]: connect from unknown[92.118.38.42] Feb 26 11:43:52 rafa postfix/submission/smtpd[13829]: disconnect from unknown[92.118.38.42] Feb 26 11:44:04 rafa postfix/submission/smtpd[13829]: warning: hostname ip-38-42.ZervDNS does not resolve to address 92.118.38.42: Name or service not known This repeats over and over (I already blocked this IP on firewall). I wonder what this attacker(?) is trying to do - the client doesn't attempt AUTH or anything (it would be logged). It just connects and disconnects. And so on and on... -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub."
