I could be wrong here, but both of these sound like reverse-DNS problems to me. Check that reverse-DNS (IP to name, rather than name to IP) is correctly set up & see if that doesn't make the problem go away. (Apologies if I'm wrong here, suffering from long-term sleep-dep...)

a personal question because I'm having kinda same problem. Do you have a DMZ? Do you have internal dns and public dns?
I have a problem like yours but only from my internal net. Clients from the "outer world" dont have any problem, inside hosts have timeouts.

I'm running Qmail with vpopmail and qmail-scanner. For the past 2 years there were no problem but recently the problem starts. SMTP Server is too slow to respond. it takes more than a minute for it to response. My DNS is working fine and there is no problem even resolving the mail server. I know the DNS is the source is this problem but seems its not.
