I currently use dovecot as my imap server. I use Thunderbird as my email client.
Thunderbird and dovecot use the ~/.subscriptions file to maintain which folders are subscribed.

As I import my folders into zimbra (NE 7.1), I can see them fine with the Zimbra web client. I can not see them with Thunderbird as an IMAP client.

If I subscribe to them from within Thunderbird, I can see them fine.

My question is where does zimbra maintain this list of what is subscribed for a given user ?

I know this is stored somewhere within zimbra, because after I subscribe to the folders
via Thunderbird once, I can move to any other desktop machine and startup Thunderbird
and see the folders.

Any insights ?
