I just don't get it.  Some get bounced and some don't.  A lot of them do
get bounced thoug.  I believe it's coming from my mail server.

Is the error message coming from the senders mail server, or your
server? Any commonality between the bounced msgs ? -----Original

I'm not sure if there is a problem with the mx records.  We did have a
problem a couple of months ago and had to have the isp add a ptr record.

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

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.

Thanks!
