Mm... Ok, my email server has a DNS server configured and is the one in the resolv.conf.

so I asume it is not the DNS .
Any other ideas?

9 times out of ten, this is related to your dns in your dmz resolving to
the external address of your email server (or, not having a different
view in your DNS for your DMZ...) , thus it tries to send to that
address to which the firewall wont let him (cannot send to the external
address from within the DMZ)... I put a local DNS in the servers
sometimes. Other times i use a view on the main DNS server.

Hello everyone, I have the following problem.

I have been trying to send email to from my domain, but it
seems that it can't reach the server.

when I do a
dig mx
I get: MX 10 MX 10 MX 20 MX 30

and if I telnet to port 25 on I get an answer.

I am usging qmail-1.03 + vpopmail5.3.11 + qmailadmin-1.0.6 + ezmlm-0.53
+ courier-imap-1.6 + clamav-0.65 +  spamassassin-2.60 + qmail-scanner 1.20

on a Redhat advanced Server 2.1

Is there a way I can determine why this email is not being sent?

To other sites the server is delivering with no problem

Thank you very much for all your help
