So, here is the status:

I have upgraded from many other versions without problems. Things were working fine until I started playing with a little backup script I had. The backup script did not do anything to Zimbra itself, so I am perplexed as to why this started happening. It's likely unrelated.
THE PROBLEM: Everything works great EXCEPT for sending mail through the web interface. This is the error that appears:
A network service error has occurred.

This is what shows up in the log...

I have tried many things and read many other posts but I do not see a problem exactly like this.
Any advice?
