Re: Xapian searches in Cyrus 3.0

Sorry, but no. You are right that the *indexes* are generated properly when 
you sync, but I was talking about *conversationsdb*. That is *not* updated 
when syncing from 2.4 to 3.0. You need ro run ctl_conversationsdb for each 
user, otherwise Xapian won't find any messages.

ctl_conversationsdb -z USER
ctl_conversationsdb -b USER
