Problems sending Emails.. I need some help to get it resolved.

[Papagayo]

My company is trying to send an email to a person in Wright Patterson Air Force Base.

It seems that it's being blocked by a gateway.. I'm getting the message from the gateway in Chicago.

here is the error message (I've replaced the real name with John Doe for the post):

Other company's has no problem sending an email to this person.. The problem only happens when anyone tries to send the email from our company.

What looks like is happening is that your SMTP server is having problems either looking up the mail exchange server for the wpafb.af.mil domain, or that it can't find the IP address for any of the mail exchange servers it did find.

According to the tool nslookup, these are the mail exchanges for wpafb.af.mil:
Primary: mr2o.wpafb.af.mil (129.48.104.214)
Secondaries: mr1o.wpafb.af.mil (198.97.67.51), mr3o.wpafb.af.mil (198.97.67.53), and mr4o.wpafb.af.mil (198.97.67.52)

I'd hop on (or have your sysadmin) hop on your SMTP mail server and attempt the same thing. You can try it out yourself by opening a DOS command prompt (or command shell on a Unix box) and type:

shell> nslookup -type=MX wpafb.af.mil
Default Server: ns.domain.com
Address: 1.2.3.4

Non-authoritative answer:
wpafb.af.mil MX preference = 5, mail exchanger = mr1o.wpafb.af.mil
wpafb.af.mil MX preference = 5, mail exchanger = mr3o.wpafb.af.mil
wpafb.af.mil MX preference = 5, mail exchanger = mr4o.wpafb.af.mil
wpafb.af.mil MX preference = 100, mail exchanger = mr2o.wpafb.af.mil

wpafb.af.mil nameserver = mr0o.wpafb.af.mil
wpafb.af.mil nameserver = mr1o.wpafb.af.mil
wpafb.af.mil nameserver = mr2o.wpafb.af.mil
wpafb.af.mil nameserver = mr3o.wpafb.af.mil
mr1o.wpafb.af.mil internet address = 198.97.67.51
mr3o.wpafb.af.mil internet address = 198.97.67.53
mr4o.wpafb.af.mil internet address = 198.97.67.52
mr2o.wpafb.af.mil internet address = 129.48.104.214
mr0o.wpafb.af.mil internet address = 198.97.67.50
