View Full Version : [ubuntu] Installed postfix - But how to relay to external domains via outlook?

May 17th, 2008, 07:40 PM
I've installed postfix and its setup according to the below documentation


I can relay from the server console to hotmail fine. From outlook I can relay to mydomain.com without any issues. From outlook though as soon as I try and relay to an external address eg, hotmail, gmail etc I get a message bounce back saying "Relay access denied".

Googleing it looks as though I need to enable SMTP AUTH but I haven't come accross a decent guide that works with my virtual user setup. Can anyone suggest a good guide or list the steps I need to take so that I can relay via my server using username/password authentication? Anonymous open relay has to be disabled to stop spammers abusing my server. I'm using ubuntu server cli 6.
