It's not a user account, because for that site, i see only 1 user, and
exactly know that this guy don't spam, and is really not from the location
of the senders IP.
Like i say, i try many of our servers with the relay test from :
http://www.abuse.net/relay.html
and this tell me exactly :
Relay test result
Hmmn, at first glance, host appeared to accept a message for relay.

and i receive the relay test email... ;(

For only one of our servers, this test is ok, and show us that the relay is
forbidden. But why not all the other ???
I try again to disable the 'popbefore', save it, and re-enable it with
save... Nothing helps....

Well, the problem is that i cant see or find anything. All i know is that i
received over 2000 mails back from AOL, telling me that :
Your e-mail is being returned to you because there was a problem with its
delivery.  The address which was undeliverable is listed in the section
labeled: "----- The following addresses had permanent fatal errors -----".

Like you told me, i created a new user, and defined it in my outlook, but
without using pop before.
It worked fine! The mails are out, and i don't receive any relay error
message, like it have to be !?
Also tryed to disconnect and reconnect my internet, only to receive a new
IP, and instantly send a mail. I double checked if my outlook try the pop
before, and i don't see that. He send it without asking for something ;(
Thank you for any good idea.
How can i try to look, and which files ?
