dovecot - Dec 2006 - Feature request: don't allow subscriptions to deleted mail boxes

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.

I thought Thunderbird unsubscribed before deleting a mailbox? In any  
case this is a Thunderbird bug.

Having subscriptions for non-existing mailboxes is sometimes wanted.  
At least with mboxes some MUAs go and delete the mbox whenever it  
gets empty.

In any case IMAP RFC says that it shouldn't be done, so Dovecot's  
behavior won't be changed. That's how it works with all the other  
IMAP servers as well.
