No outgoing mail with outlook pop3

[aniewels]

Hi i've got an urgent problem with outgoing mail.

atm we have some premium users an a lot of pop3. and we are just waiting for the decision of the board, how many licences we'll buy.
meanwhile we need the pop3 accounts.

Receiving mails works for every kind of user

but:
Premium Users have no Problem
Pop3 users using the swa have also no problem
Pop3 users, using outlook, can send internal mails, but no external.

Error: 550 due to spam...

I've tried some accept rules in smtpd.conf but with no result. even "RELAY accpet ALL" doesn't help.

where else should i look?

edit:
actually i should try not to fall in panic that fast :)
sry again.

for all with the same issue:
AUTH_SUCCESS accept ALL in smtpd.conf
omoff -d0 smtpd
omon smtpd
and in OL "Server requires auth..."

Denied due to spam list means that the submitting client has been rejected because they do not match with the RELAY accept rules in smtpd.cfg.

The simplest solution is to have the POP3 clients authenticate with the SMTP server.
