A few of my clients have reported "retry timeout exceeded" errors when sending mail to certain hosts.

They will send the email and they will get this message returned to them:

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

[email protected]
retry timeout exceeded
Any idea how to fix this issue?

Check the email log for more details.

Might be the mailbox is full or disk space is full or the wrong permissions or sometimes spam filters may be blocking the mails.

Over the past month I have still be getting a lot of these "retry timeout exceeded" errors, on domains where there shouldn't be a problem like Lockheed Martin for example.

I don't think there is a firewall installed, how can I check that?

I tried the iptables -F, not sure if it did anything, it didn't tell me anything at the command prompt.
