I concur! This is expected behavior for non-authenticated persons.....
Server doesnt allow open relay as you are trying to relay mails. Do the outlook/thunderbird client have "myserver requires authentication" enabled ?
The MUA does have required authentication enabled in which it claims that Zimbra doesn't support authentication?
I have tied STARTTLS and none for secure authentication which didn't work.
My username however is in the authentication box, only the system doesn't ask me for a password. When I had the server setup and running initially using Seamonkey on Ubuntu Linux everything was fine and I could connect without any issues. I then rebooted my system into OpenSolaris and attempted Thunderbird which didn't work then booted back in to Ubuntu and tried my working version of Seamonkey which then subsequently stopped working also??
I am totally confused since this is not 'normal' behavior! Ie. there's no reason for the system to just stop working. Unless I performed an update to the system through yum which kicked something out?
Memory looks ok:
CPU is running at mostly idle....
