I want to send email from an external IP, roaming, Laptop. I can receive IMAP just fine. Sending from the web interface is also fine.
Client = OS X's Apple mail.app
I have searched the forums and read lots of similar posts, and the admin manual also.... But have not found the answer to my problem. Please point me in the right direction(s) and I will do the reading.
P.S. love the Zimbra app =]
