Example:
* I have 100's of sent-mail mailboxes I don't want to be subscribed
to, because it is doubtful I will ever use them. These mailboxes are
unsubscribed because I don't want to see them in any mailbox listings
by default.
This use of subscriptions is a terrible abuse of IMAP. Like most
terrible abuses, it's a-ok to choose for yourself if you're an
advanced user, but anyone who has done support for a broad user base
knows that a client should *NEVER* act like this as the default.
Subscriptions are brittle and non-portable and hiding mailboxes based
on them leads only to floods of "Where is all my mail you screwed up
my life!!!!" interactions.
I'm genuinely confused by this come-back. Could you elaborate?
Why is having subscriptions (and, specifically, some folders to which
you are not subscribed) a terrible abuse of IMAP? What is non-portable
about subscriptions? The IMAP protocol supports them directly.
