I used the Contrib. It worked flawlessly. Thank you!
The only non-standard thing I did was to move a license code from a ClearOS server that I had previously set-up to the SME server. It has worked fine and I believe that I found my problem which can only be filed under the duh heading.
I currently have 10 users using Zarafa once you include the admin user (which I wasn't counting but the folks at Zarafa were). So with a license of just 10 users I didn't have any additional users available so zarafa-admin would not show the 11th user. I am looking into adding additional users, but the purpose of this exercise was to enable bayesian learning for spam reduction. So instead of creating a new user just for the Bayesian function, I used an existing user. So far, everything seems to work.
Thanks!
