I have Plesk 7.5.3 Reloaded on Fedora Core and I'm having a couple problems with qmail. 1. When I go to send a message I get the annoying 30 second delay. I 've change /etc/xinetd.d/smtp_psa to include server_args = -Rt0 yes there is space on either side. I also setup the firewal to REJECT rather than drop packets with a source and destination of 113. 2. I get a lot of '553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)' messages with SMTP_Auth both with Auth and pop3 before smtp features. I've setup whitelists for a couple locations for now, but that won't work for all our clients. Any help would be appreciated.
