[cobalt-users] SMTP doesn't work: 554 rewrite error

[July at Zerowait <july@xxxxxxxxxxxx>]

I've seen this error from another user. Anyone got an answer??? Finally
got POP working. This is the last obstacle....

When I send  email from outlook, I get the following error message:

The message could not be sent because the server rejected the sender's
e-mail address. The sender's e-mail address was 'jlinett@xxxxxxxxxxx'.
Subject 'From jollyco.com', Account: 'Jollyco Server', Server:
'www.jollyco.com', Protocol: SMTP, Server Response: '554 rewrite:
excessive recursion (max 50), ruleset 3', Port: 25, Secure(SSL): No,
Server Error: 554, Error Number: 0x800CCC78

Is this caused by our not having the reverse DNS at our upstream
provider? Or is there something else I'm missing? jlinett is a valid
name for a user in the domain.

Thanks,
July
