Is there a problem with the published MX records for your domain?
Do you have any blocked IPs on exchange or your firewall?

Subject: [exchangelist] smtp;521 Server does not accept mail

Can anyone tell me what this means? smtp;521 Server does not accept mail.  I
am running NT 4 sp6a, Exchange 5.5 sp4?  I can send and receive emails but
others are telling me there are problems.  The problem is with outside users
sending to us.
