How do I set all my mailboxes to "subscribed"

Hi all,

I've had a great deal of trouble accessing my Dovecot IMAP from most supposedly IMAP aware email clients, and have been advised that it might be because some of my email folders are not subscribed. Is there s way I can subscribe all my folders? I see no reason to have a folder not subscribed.

Thanks,
