I am brand new to Zimbra and very new to exchange administration.
I have a functional exchange server which delivers mail to my Zimbra desktop client fine but I cannot send mail. The log says:
2008-03-07 12:12:49,469 INFO [btpool0-51] [email@example.com;mid=2;ip=127.0.0.1;ua=ZimbraWebClient - [unknown] (Win)/0.0;] offline - SMTP send failure: Fwd: Message Title
I am certain that it is the account setup in Zimbra for outgoing mail.
I don't know how to find the correct servername and port because I have tried every combination of what I can see on my exchange server.
MX1.DOMAIN.COM ports 25, 143 and 993
SMTP.DOMAIN.COM ports 25, 143 and 993
Where DOMAIN is our real domain name.
What am I missing?
