Hi Guys!
I'm having a hard time with postfix while I try to send emails using my
PF-SERVER.
Postfix is running perfectly, the problem is that I get some delay when
sending the emails depending on the sender's domain address.
In this case, the problematic domain name is zoom4u.com.br.

Hi,
Actually I believe that there is a DNS problem on that MX server,
cause PTR is set properly.
The delay is not on the delivery, but when my application connects to
the MX SERVER and send the messages. When using ZOOM4U.COM.BR, my
application sends only 2 messages per second and there is no
Looks like POSTFIX is checking something on each delivery try using
the SENDER DOMAIN.

My own PTR lookup fails with NXDOMAIN.
Can you show the missing logfiles records that I asked for?

The major delay is at (c=connection setup time including DNS, HELO and TLS).
Thats what is taking too long, but ONLY when I use sender
ZOOM4U.COM.BR as the domain name.
Any idea??
