ipchains -A input -p tcp -s 212.232.168.180/32 1024: -d 212.232.168.183/32 113 -i eth0 -j ACCEPT # Don't worry guys, there is no auth server running on 212.232.168.183, it's there because of sendmail. I still didn't find a suitable solution to make it faster although I'm sure there is one.

Aehm, let me ask you what exactly you mean by this? Is it the problem that sendmail queries authd when sending emails? Disable it, if that is your problem. Or am I misreading anything? Thanks Raffy
