Hi there

We had been using the stock Ubuntu Dapper Dovecot which is an early
1.0 beta but just upgraded to 1.1.1 to fix some read flag issues
with Horde.

Previously dovecot seemed to ignore files beginning with "." in the
~/mail (mbox format) directory but now shows them.

Right. The change was done two years ago.

There doesn't seem to be any switch in the dovcot.conf file to
change this. Any such settings are about maildir.

There are already too many switches..

Is there anyway to make dovecot-1.1.1 ignore hidden files?

No. Why do you want that?
