Hi all, I use Plesk 9.5.2 on an OpenSue 11.0 (X86-64) host. As emailer I use qmail. However I noticed that when I switch on server wide grey listing emails send from an email account which is using the smart host of an ISP get stuck in the greylisting and show up with a big delay time if at all. If I use an email account which uses a fixed IP with a proper DNS name assigned all went through fast. Switching greylisting off and the emails arrive in time no matter from what. If I inspect the problematic account I see the Dial UP ip in the header even when send through the ISP smarthost. I see this messages when greylisting is on and messages don't get through: What am I missing ??? I have seen issues with postfix but I have no idea what's wrong here.
