I have seeing a strange entry in my Exchange SMTP Virtual server logs.
Every 15 minutes or so, I see this entry:
2003-11-18 23:41:13 220.127.116.11 OutboundConnectionResponse SMTPSVC1 (MYSERVERNAME) - 25 - - 558+Your+network+address+is+blacklisted,+his+means+that+spam+is+detected+from+you.+If+you+think+this+is+not+correct,+email@example.com(#5.7.1) 0 0 155 0 453 SMTP - - - -
I have checked every black list in the world that I can find, and we are not listed in any, nor are we an open relay, nor are we spamming. the strange thing is that this entry is always all by itself. There is no other connection related data accompaying it, and no evidence that my mail server is attempting to send messages to this "Gawab.com" domain or the IP address listed.
