I'd like to configure my dovecot service to use the IMAP SPECIAL-USE

well, in my experience SPECIAL-USE is just a suggestions to clients. Check RFC 6154 for MUSTs, you'll find only few. Hence, how the client (or the server) behaves in a special case is implementor-defined.

In other words, expect the unexpected. I'm especially curious what happends when you have multiple mailboxes with the same special-use.

There was a similar discussion about this on list some time ago, about whether or not Dovecot could utilize special use 'aliases' that your clients may want to use by default, and Dovecot would automatically map those requests to a single mailbox. ... Personally I would love to see this implemented.

Yeah, that would be cool. For an existing installation, though, an admin might have merge all existing mailboxes into the one actual mailbox to keep the confusion down.
