Hi everybody,
I was using Postfix without any problems but last two months time the traffic usage of the server is increased too much. When I checked the mail queue I see emails for an account [email protected] which does not exist on my server. Below is an example how the mail queue looks like. I checked for open relay both manually and some online sites. There's no open relay. Is this a kind of spam method? If yes, does anyone give me an idea how to fix it. Kindest Regards Ceyhun Email queue: AC5A615038A 635 Mon Apr 1 03:47:47 [email protected] (connect to mx1.likya.com[192.168.255.255]: Connection timed out) [email protected] A05E7150098 635 Sat Mar 30 13:33:46 [email protected] (delivery temporarily suspended: connect to mx1.likya.com[192.168.255.255]: Connection timed out) [email protected] ABDC81500CB 641 Sun Mar 31 05:28:05 [email protected] (delivery temporarily suspended: connect to mx1.likya.com[192.168.255.255]: Connection timed out) [email protected] A333F150086 2786 Sat Mar 30 09:55:01 MAILER-DAEMON (delivery temporarily suspended: connect to mx1.likya.com[192.168.255.255]: Connection timed out) [email protected] A594015008E 629 Sat Mar 30 12:03:53 [email protected] (delivery temporarily suspended: connect to mx1.likya.com[192.168.255.255]: Connection timed out) [email protected] A122F150381 631 Mon Apr 1 00:34:18 [email protected] (delivery temporarily suspended: connect to mx1.likya.com[192.168.255.255]: Connection timed out) [email protected]
