[Dovecot] Separate auth for pop and imap

Hi.

Is it possible to set up separate authentication backends for POP and IMAP for a single Dovecot instance?

Or does this require two separate dovecot instances with separate config files?

Specifically, I want to have one database query for IMAP and one for POP so that I can let these be separate features that I can flag in a database.
