Help: Qmail unknown users spam
Hi,
I have qmail mailserver (Virtual Users & Domain). I have taken most of the anti-spam measures like spam assasin,qsheff(built-in ani-spam regex) scanner and clam av. I'm also using RBLSMTPD (spamhaus SBL rules) Quote:
Note: 192.168.1.2 is the Private IP of my mailserver. Quote:
I get several spam emails quarantined and the from field contains non exsistent users and the recipient field contains both exsistent and non-exsistent users.. For eg. From: non-exsistent.user@mydomain.com To: exsistent.user@mydomain.com I checked the qmail.org site and there is a patch called check user but i cannot mess my live qmail setup by recompiling it. Is there any way i can stop this without requiring any recompilation ? |
Please any qmail master comment I'm taking an effort to understand things :(
ok i compiled qmail-smtpd with this smtp-auth patch over here: http://members.elysium.pl/brush/qmail-smtpd-auth/ I use Vmailmgr with qmail and followed the instructions over here: http://members.elysium.pl/brush/qmai...th/faq.html#a4 I telnet to my mailserver give EHLO command and see this: 250-AUTH LOGIN PLAIN 250-AUTH=LOGIN PLAIN 250-PIPELINING 250 8BITMIME but the Authentication doesn't work at all. this is how i changed my smtp startup script. Quote:
I have also chmod ug+s checkvpw ! this is the POP3 entry in my startup script. Quote:
thanks |
ok no one has an answer. applied my mind and found a simple solution. What i did is since it is an SMTP after successful POP3 authentication which will then automatically allow the client to relay, i just remove the line "mydoamin.com" from the file /var/qmail/control/rcpthosts
Note: I can remove mydomain.com becoz I have an external Mail host service provider from whom i download messages using fetchmail and deliver local users. Thanks all. |
