[Dovecot] Thunderbird, subscriptions, and upgrade to 1.1.3

[Jack Stewart]

Hi,

I've upgraded from 1.0.7 to 1.1.3. When I did this, my Thunderbird lost 
its brain and did not show some subscribed folders. squirrelmail also 
seemed to have issues. Applemail and mutt were fine. The configuration 
output is below.

Hopefully this is just me and just random bizarreness. There wasn't a 
problem in 1.0.7 but I could have been caught in mid-upgrade.

Thunderbird did not seem to update the subscription file (or at least I 
could not find the one it thought it was using).

Any pointers are appreciated. Thanks in advance.
