SUMMARY: sendmail problem

2007-12-25 0:45:00

Thanks to all that replied. It looks like our mail server is not
resolvable via DNS outside of our domain and that's the reason we are
not being responded to by the remote mail server. My original question
is below.


Original question:

Managers,
I am attempting to send mail to a user at foo.com. When I send a
message from my domain, I have trouble establishing a connection with
the remote mail server. I get the following when using sendmail with
the -v flag:

user at foo.com... Connecting to mailman.foo.com. via esmtp...
user at foo.com... Connecting to smtp.foo.com. via esmtp... user at foo.com...
Deferred: Connection timed out with smtp.foo.com.

It tries each remote server (mailman.foo.com and smtp.foo.com) for
several minutes before timing out. If I send an email from another
server outside of my domain, everything works fine. Could it be that my
domain is being filtered out and rejected at the remote site? Please
send me your ideas on what the problem might be.
Thank you, and will summarize.
