[enhancement]: Document how RFC6154 special-use mailboxes are created

[mcassaniti]

Which feature or improvement would you like to request?

IMAP supports marking certain mailboxes as special use such as for SPAM, Sent, Drafts and Trash usage. An example from Dovecot is available here which might make a bit more sense. Not only do these special mailboxes automatically get created on first logon for the Dovecot case, they are appropriately annotated so a client supporting special use mailboxes will know what they are used for.

Currently Stalwart does support RFC6154, but I didn't see any documentation noting:

• If these mailboxes are automatically created
• How to create them which might simply be noting that your client needs to send the right data along

If special use mailboxes are not being automatically created I will raise another feature request to add support for it similar to the Dovecot example. It does make a new user setup quite easy.

Is your feature request related to a problem?
