dovecot - Jan 2008 - Test Environment Question

I have my master IMAP server running DC V1.0.10.  The homedir and 
INBOXdir are physically resident there and NFS exported (no caching) to 
3 other machines.  I have installed V1.1beta13 on one of them (which 
thus accesses the homedir/INBOXdir remotely) and plan to have a limited 
community test-drive it there.  Are there any hazards or drawbacks in 
doing this?  While the homedirs and INBOXdirs are thus shared, I have it 
so that each machine has its own local index directory and /var/run 
dir.  Comments or dire warnings?

Is there a way of setting dovecot to use two mysql authentication databases, 
either in a live/failover format or a round robin method.

Regards

Yes, just provide as many MySQL hosts as you wish in "sql.conf"

"connect = host=mysql1 host=mysql2 dbname=mail user=dovecot .."

MySQL hosts are queried in round-robin fashion.

If indexes are separate, there should be nothing to worry about.
Although with the beta13 machine you could enable NFS attribute cache
and set mail_nfs_storage=yes. If there are no bugs it should improve
performance.
