I am setting up Zimbra 7.1.4 Open Source edition for a demo and need to set up a relayhost that requires authentication. There are wiki instructions:
Outgoing SMTP Authentication - Zimbra :: Wiki
...but it says this applies through Zimbra 6. Should this procedure also work with Version 7? (No luck so far.)
I know how to manually configure postfix to do this, but don't think I'm supposed to be monkeying around with /opt/zimbra/postfix/conf/main.cf.
What's the best way to accomplish this? (I'm kind of surprised there is still no setting in the admin web interface to do this.)
