Dear All
One of my user machine was infected by a virus and it start sending lots
of spam mails. As the user was using smtp-auth my server accepted the mail.
Because of this my server IP is blacklisted, after diagnosing i have
blocked the infected machine IP through iptable and scanned for virus.
Now the problem is solved, but i wanted to know how to control this behaviour.
With Regards
Vinay
