I'm afraid I can't help you debug what's required to get mDNS working
in a Debian chroot jail. The simplest solution is to not chroot the
smtp(8) delivery agent. You might find some help on an appropriate
Debian forum.
Perhaps /var/run/avahi-daemon or similar needs to be bind mounted in
the chroot jail, but that's just wild speculation:
