You can't do this with a single instance, but you can run parallel 
instances of dovecot on the same machine.  Create a second 
dovecot_mumble.conf with the alternate config and start the second 
instance with -c /path/to/dovecot_mumble.conf.  Each instance needs its 
own .conf (they can share sql/ldap config files), base_dir and auth 

I run multi-instance setups in production--it makes it possible to take 
down the imap service without breaking postfix since postfix smtpd will 
have fatal startup errors unless dovecot is running.
