SMTP authenticated Relay - 15.Jun.2010 9:29:06 AM

Hi All

Pulling my hair out here. I have a stand alone exchange 2007 box,and need to enable users outside the network to send / relay mail via SMTP.
Permisions on the default connector as follows
NT AUTHORITY\Authenticated Users {ms-Exch-Accept-Headers-Routing}
NT AUTHORITY\Authenticated Users {ms-Exch-Bypass-Anti-Spam}
NT AUTHORITY\Authenticated Users {ms-Exch-SMTP-Submit}
NT AUTHORITY\Authenticated Users {ms-Exch-SMTP-Accept-Any-Recipient}
When I attempt to send a message via a client like outlook express, I tick the my outbound server requires authentication, but still get a relay denied.
The exchange users group has access to this connector.
What am I missing here ??

Thanks in advance

Your statement is confusing on the fact that why setup a relay connector and try using authentication from Outlook express to test it?

Also don't bother with the permissions on the receive connector. The best practice is to create a seperate connector for relaying and selecting "Externally secured" option in Authentication tab. You also need to remove the default "0.0.0.0-255.255.255.255" IP range from the Network tab(on remote IP range section) and add only those IPs from which you want to allow relay mails from.

Thanks for the reply - I needed external LInux OS users to be able to send mail from outside using authenticated SMTP. Turns out my issue was something completely different, but worth noting.
The exchange servers sit behind a PIX firewall, and I had SMTP protocol fixup set, this works fine for general mail, but doesnt allow advanced requests like SMTP Auth. My configs work actually perfect. Turned of SMTP fixup on PIX and hey presto :).

Still a day of pulling my hair out ....
