Earthlink maintains it's own Black Hole List that applies to all their
domains (earthlink, netcom, mindspring, rmi, etc)  If you have ever been
an Open Relay, try sending email (with the bounced message and you
mailserver ip and domain) to

openrelay@xxxxxxxxxxxxxxxxxx

http://www.MSExchange.org/

I am running SBS2000 (Exchange 2000 sp3). The after double checking
against 
Mark's article, the relay settings are just as described.

Not all the time, but frequently we will get error messages to all
earthlink 
accounts:

There was a SMTP communication problem with the recipient's email
server.  
Please contact your system administrator. #5.5.0 smtp;550 relaying to 
_________@xxxxxxxxxxxxx prohibited by administrator.

Frequently with one other organization/domain to whom we frequently 
communicate we receive the following error:

You do not have permission to send to this recipient. ... #5.7.1
smtp;550 
5.7.1 Unable to relay for ______@xxxxxxx

I don't know if they are related problems or not. For a while I thought
this 
was a problem with the recipient's server, but I don't think earthlink
is 
down as often as I receive these errors.
