I have a post in about Open Relay. (
http://www.zimbra.com/forums/install...elay-help.html)
I was told that Zimbra has open relay disabled by default. After running test from
Mail relay testing. It reported no relays accepted.
But if I telnet into my server from an OUTSIDE network and run the following command:
telnet server.myserver.com 25
Trying myipaddress...
Connected to server.myserver.com.
