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.

Hi Sergio
I dont have a DMZ and I have only public DNS.
I have problems in both internal net and outside world.

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...)

Are you using inetd or tcpserver? And is there any NAT between the smtp
server and its dns resolver?

Hi,
tcpserver (last release)
NAT only at the FW, routing to the inside net. Kinda like this
WWW---FW with PublicIP--NAT--SMTP---routing---Internal Network

Did you add -H -l yourlocalname to your tcpserver?
It avoids consulting DNS for changing IP to names. When it looks for not
existent names, or when yout DNS server is working bad, you have huge delays.
If you have a private address as sender or receiver, no public DNS will be
able to traslate
Antonio,
My qmail-smtp/run goes like this:
#!/bin/sh
QMAILDUID=`id -u qmaild`
NOFILESGID=`id -g qmaild`
exec /usr/local/bin/tcpserver -c 50 -D -H -R -v -P -l 0 -x
/home/vpopmail/vmail/etc/tcp.smtp.cdb \
-u $QMAILDUID -g $NOFILESGID 10.0.0.200 smtp
/var/qmail/bin/qmail-smtpd 21
