In this specific case, the Spammer authenticated with the "legituser" account !!! (as confirmed by account name after the RECV in the log : 'RECV=OK" "legitusern...@legitdomain.com"') So before any others solutions, start changing que legitusern...@legitdomain..com password (with a complex one) !!!! And tell you"legituser" to completly scan all of it's computers for trojans/viries/... BEFORE changing the password at its side (to avoid spammers recover the new password)... -----Message d'origine----- De : xmail-boun...@xmailserver.org [mailto:xmail-boun...@xmailserver.org]De la part de Fred Envoyé : mercredi 6 juillet 2011 19:36 À : xmail@xmailserver.org Objet : [xmail] Getting hammered bad Hello all, I need help to fight against spammers, here is a sample of an smtp log entry: "mail" "mail" "72.16.236.115" "2011-07-06 12:46:21" "ALEXSERVER01.ANDREWALEX.local" "hotmail.co.uk" "vreaus...@vreausutelog.com""obbard_d...@hotmail.co.uk" "SE86331" "RECV=OK" "legitusern...@legitdomain.com" "2507" "" I am receiving sometimes hundreds of this kind of email in a short time. I have tried black listing the IP and sender domain in spam-adress.tab and spammers.tab but they just change both and they spam again. The email legitusern...@legitdomain.com is a legit user on my server. I am using spamassassin, spf filter and RBL checks… Anyone has any ideas how to block these ****ers. Thanks Hi there, yes, I had the exact same problem. I was so frustrated I wanted to break something ! Anything ! Put sentiments aside. This is really true. The first thing you have to do is have strong, repeat STRONG passwords. Also, if you have any drop-lists (aliases, lists, whatever you want to call it), password does play a very significant role and you will have to equip these list accounts with strong passwords again.
