How do I set all my mailboxes to "subscribed"

[Steve Litt]

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,

SteveT
