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...)

Hi Nasib,

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.

Regards,
SRosa

Dear all,

  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.

Please help!
