[Dovecot] Feature request: don't allow subscriptions to deleted mail boxes

[Erik van Oosten]

Hello,

Due to Thunderbird's mailbox deletion problem I was able to remove a 
mailbox while keeping the subscription. This was hugely annoying as 
Thunderbird is totally incapable of removing the subscription, even 
though the mailbox is long gone. It took me a while before I found a 
work around: I had to actually log in and remove a line from the 
.subscriptions file. You will probably get the same problem when you 
manually delete or rename a mailbox.

So here is my feature request: please check for subscriptions to 
non-existing mail boxes and delete these when found.

I am not sure what events would be appropriate for triggering the check, 
but I am sure there are some.

Environment:
- Dovecot 1.0 rc15
- SuSE Linux 10.0
- Thunderbird 1.5

Regards,
    Erik.


PS. Thanks for Dovecot, it is the best IMAP server I have ever used.
