[Dovecot] old messages being delivered to blackberry

[Luc Belliveau]

I've switched to NFS instead of GlusterFS, and the problems have 
disappeared.

It's too bad... GlusterFS had some nice features ...

I'm no longer getting index related errors... but the expunged error is still occuring... and the error seems to happen a few moments before the BB gets a bunch of messages... so it's very likely related.
