failed initial sync on .53

[gpdude]

Hi,
I've been using zimbra through a service provider for a couple weeks. I am now trying to get the desktop up on main linux desktop (too many computers...)
The installation appears to work correctly, I put in my account and password and it passes the test. Then when it tries to sync for the first time I get this in maillog:

Just for grins, i tried deleting the entire install and then reinstalling. I still had the same problem.
I looked in the forum and didn't see anything that looked like this, so I am posting a new thread. If this is a RTFM, please point me in the right direction.
thanks,

jerry
