Can't Recieve Email from the Outside World

[djbflea]

We had a working email server for long time until this past Saturday. After spending the better half of last three days going the logs and forum we have had no luck. Logs don't seem to indicate any real error. We able to send and receive email internal and we can send emails to the outside world. Every time an outside MTA tries to talk to our server, our server says please try again later.

Any and all suggestions would be greatly appreciated!

Here is some of the log:

[jeremy-fleming]

is Clam running right?

do you have more than one domain on this server? if you do, can they get mail at all?

[djbflea]

yes other domains work, the main one does not.

clam seems to be working fine.
