[Dovecot] dovecot imap mbox multiple connections

[Danni Allen]

Hi,

The company that I work for are currently looking at a changeover in 
clients from pegasus mail(v4) to Thunderbird (v1.5.0.8).  We run dovecot 
(v 0.99.13) with mbox.
We currently have a bunch of shared folders sitting in a dummy imap 
account that they all connect to and view.  I have read that problems 
with Thunderbird have been encountered with this setup due to multiple 
connections to the account and that a possible solution is to convert 
from mbox to maildir.

I was simply wondering if anyone knows anything about this, as I don't 
seem to be able to find any information on it other than a single thread 
with a single comment with what seems like anecdotal evidence rather 
than something acknowledged.  Is there a problem with this?

Rgds,
Danni Allen
