Shalom Crummy,

You give us very little to go on.

Few possbilities: Your IP address has been marked by the army as a spam source and your mail is being stopped.

Perhaps you are not using the right smtp relay server.

Perhaps the server mx.us.army.mil does not permit smtp relay from your system.

Tell us a little more and maybe we can provide some useful help.

Their mail server is not accepting connections from your host. Not from mine either.

It could be down, or only accepting connections from certain places. Have you tried sending the message through the mailserver of your provider ?

Cheers

Shalom,

For reasons only the military knows they have decided mail from your system should not be received.

It is common to not accept mail for the following reasons:

1) Lack of a reverse DNS record.
2) Not using a recognized smtp relay server.
3) Inconistent DNS structure for you IP address
4) Incorrect sendmail configuration.
5) Many,many others.

You may have to contact the US army to find out why you have been blocked, but first check the list above. Good luck getting an answer for them.

I hope the email address you gave as an example is not real. If it is, its not going to make them more likely to talk to you posting their email addresses publically where spammers can harvest them.
