I'm using
$ /usr/sbin/dovecot --version 2.0.15
on
$ cat /etc/fedora-release Fedora release 14 (Laughlin)
and version 8 of Thunderbird.
I use dovecot locally for internal only access to my email archives, of which I have many gigs of email archives. Over time I end up subscribing to a couple dozen different IMAP email folders. Problem is that periodically my list of subscribed folders get zapped to none, and I have to go and re-subscribe to a dozen or two folders again.
Anyone seen this happen? It looks like the list of subscribed folders is here ~/Mail/.subscriptions and I can see in my daily backup that it reflects what appears in TBird. What might be zapping it? I use multiple email clients simultaneously on different hosts. (IOW I leave them open) Is this a problem? Does dovecot manage that in some way? Or is that my problem? I don't think this is the problem since this only occurs like a few times per year. If it were the problem I'd expect it to occur much more frequently.
Thanks for any clues Mike
