Hi,
I have setup Virtualmin GPL a few days back, and everything is working except for outbound mail, which goes from my mail server to an external mail server, using smtp authentication.
This is the error I keep getting:
postfix/qmgr[1758]: 3F709428057: from=test@test.com, size=5707, nrcpt=1 (queue active)
postfix/smtp[1793]: 3F709428057: to=recipient@hotmail.com, relay:25=relayserver.com, delay=1.4, delays=0.02/0.01/1.1/0.29, dsn=5.7.1, status=bounced (host relayserver.com said: 554 5.7.1 recipient@hotmail.com: Relay access denied (in reply to RCPT TO command))
This is the output of postconf -n:

The domains can receive mail, but cannot send any outbound mail, as the external server throws up the error and rejects the mail. I am sending the mails using the Webmin interface.
Virtualmin was installed using the automated installer and the version is 3.79 GPL.
