This Message was undeliverable due to the following reason:

A message was not delivered because a loop was found in the Mail
eXchanger record database (the MX loop condition). The destination
host has an MX record that points to this host, but there is no
account for the designated recipient.

Here are a few possible solutions for clearing up this problem:

- add the domain name to your list of Local Mail Domains
if this mail server has complete authority over all
mail accounts within that domain

- return the mail since the address was invalid

- fix the MX records in the DNS for the host in question
and then resubmit the message

- add an account or alias for the recipient on this machine
and then resubmit the message

If this machine should be handling all mail for the destination
host, it should be added to the list of Local-Mail-Domains in
the "system" configuration.

Just off the phone with customer and 3Com told them they were sent the wrong model router to do it on their end. I just wish to be able to at least attempt to perform accounting on this circuit.

I assume there is a way to specify the RADIUS call back attributes thru the client's SA record. Particularly, if I am going to send a command to initiate a call from the PM-3's location table, which RADIUS attribute(s) are used for that? This isn't very clear to me looking thru the RadiusNT documentation and comparing notes with the PM-3 command line/radius guide. I suppose this is an idea that is implemented rarely - if ever - from Emerald.

You all are `da Experts.
