Subject: Forcibly disconnect spammers
I have Postfix, Dovecot and Amavis on my Ubuntu server. Recently, I get every 4

I would simply block the IP at my firewall and be done with it.

I have Postfix, Dovecot
I have Postfix, Dovecot and Amavis on my Ubuntu server. Recently, I get

Windows XP and maybe has a virus. Anyway, I found the way (after a lot
of Googling) to make my Postfix not delay client access checks and I
reject that IP
