If they'd do that, it would be great because that's *the* reason I'm not 
running Zarafa.

Last time I tried the Zarafa IMAP server, which is some years ago, I was 
converting email locally via IMAP, just to see how Zarafa worked and 
behaved. The conversion would hang at random times, and it's IMAP server 
was so slow compared to Dovecot that I didn't want to use it.
