Mail Delivery Issue

We've been having a strange issue with incomming mail. Sometimes when people send mail it gets bounced back to them with an NDR:

The e-mail account does not exist at the organization this message  was sent to.  Check the e-mail address, or contact the recipient  directly to find out the correct address.
      <server.domain.LOCAL #5..1.1>

Also a details file:

?Reporting-MTA: dns; server.domain.LOCAL

Final-Recipient: RFC822;
Action: failed
Status: 5.1.1
X-Supplementary-Info: server.domain.LOCAL

    This is a standard NDR that is returned when the email address doesn't exist in your organization. Try resending the message to the correct address...

    Sorry, I guess I may have worded it wrong. The addresses do exist. Sometimes they get mail, sometimes the mail gets bounced.

    sounds like an MX record issue. Check the recepients MX records. ( make sure that all mx records are pointing to valid email hosts, and those hosts are configured to receive email on the specific domains.

    The usual way that I word my response to this sort of error message is that the server the message was sent to doesn't recognise the email address. That doesn't mean it was sent to YOUR server. it could be another.
    As already suggested, look at your DNS records, make sure that they aren't pointing to another server that is perhaps no longer valid for your domain. If they are, remove them.

    Thanks for the answers guy. Everything is pointing to where it should be. I just don't understand how someone from the outside can send a mail here just fine, then have it bounce the next time, then have it send fine again.  It's just sporatic. I'm looking into the network/dns to see if that could be the the issue.
