Mail will not go out of company. Are my external DNS MX settings correct?

Here is what my Mail Exchanger (MX) shows on Server 2003 RC2:

Host or child domain: (same as parent folder)

Fully qualified domain name (FQDN):

Fully qualified domain name (FQDN) of mail server: (IS THEIR SUPPOSED TO BE A PERIOD AT THE END HERE?)

Mail server priority:

    The period is added automatically by a lot of DNS servers and is OK.  You don't need an MX record to send mail, it is used for receiving.  What kind of error message do you get when you try to send mail externally?

    I am not getting any messages when sending out. I can send internally but not externally. I assumed that it is our DNS that is the issue.

    Sounds like your SMTP service has been stopped on the mail server

    Sendmail's queue was deferring emails. I had to go in there and unclog it. The SMTP plumber some would say. Thank you for all your words of wisdom.
