Using Thunderbird-0.9.  Dovecot is running on RHEL 3, on top of 
Redhat/Sistina GFS (clustered filesystem.)  Currently I'm keeping it on 
one node to avoid possible GFS locking issues.  I'm running with 
mmap_disabled=yes, mbox format.   Most of the 1.0-test builds I have 
done eventually corrupt their index files, and show strange behavior 
(click on a message in the folder view, and an entirely different 
message opens... delete three or four messages and expunge, the messages 
instantly reappear as unseen.).  I typically wipe the .imap directories 
between different builds of Dovecot.

I've been following the -test code for a couple of months now, just to 
see how it does, because we're running UW IMAPd and are excited to have 
a way to increase the performance of our mail cluster (indexes) without 
having to move away from mbox. 

Let me know if there's more information I could provide that would be 
helpful.
