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.
I do expect that any client supporting SPECIAL-USE honors the server setting (first time it connects to the server or everytime, but at least once) and creates the mailboxes it uses itself.
Otherwise, Dovecot can autocreate the mailboxes regardless of its use: https://wiki2.dovecot.org/MailboxSettings
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.
E.g.:
Outlook clients would see/use 'Sent Items'
Thunderbird would see/use 'Sent'
But both would be mapped to a single mailbox 'Sent' (or whatever you had defined as the actual mailbox).
Personally I would love to see this implemented.
