You can't do it with one passwd-file, you'd have to use multiple per-protocol passwd files.. For example:

userdb passwd-file {
  args = /etc/dovecot/passwd.%s
}

Yeah, passwd-files aren't very flexible for things like these. Maybe you should look into using sqlite? It probably allows some if() or case() in the query (I haven't used sqlite).
