Also is this coming to F12 or just F13?
Only Rawhide (F14) at the moment. I doubt that it will appear in F13 as
it's not there yet (I'm not the maintainer btw) and the configuration
has changed from /etc/dovecot.conf to /etc/dovecot/dovecot.conf +
/etc/dovecot/conf.d/*.conf and some of the directives have changed too.
