Connection Filtering Exchange 2003
Somehow our connection filtering fails on the primairy domain. When we do a telnet, from a blacklisted server, we recieve a 250 2.1.5 test@primairydomain.com, so we are able to send mail.
When we do the same with a secondairy domain we recieve 550 5.7.1 The IP-Address was rejected............
What could be the problem ? Our server is responsible for multiple domainnames, but only with the primairy domain connection filtering won't work anymore.

when are you getting the 550 5.7.1? after the HELO/EHLO or after the MAIL FROM: ?
ASKER
after the rcpt to: test@secondairydomain.com,
proper connection filtering is as soon as you press enter after the mail from, you should get 550 5.7.0 "access denied"
5.7,1 is normally "relay denied"
is the @secondarydomain.com domain hosted on the Exchange server you are telneting into?
By default Exchange will accept anonymous messages to domains it owns (for example from the internet)
5.7,1 is normally "relay denied"
is the @secondarydomain.com domain hosted on the Exchange server you are telneting into?

Yes, both the domains are hosted on the exchange server. The server isn't relaying anything. I thought that 550 means, your server is blacklisted........
have a look at:

and you will see 550 5.7.0 "access denied" half way down the page for the "MAIL FROM:" command
try telnet into the server again and do mail from: me@externaldomain.com and then rcpt to: you@secondarydomain.com and see what happens. it should accept the message.

Problem solved.......the domain was in the placed in the accept list, so mail always is accepted, even when it was send from a blacklisted domain.
