While you are thinking about code/concept review, perhaps you
consider the sanity(?) checks for hostnames.  You have documented
the importance of unique hostnames etc for message-id creation and
that should be enough to warn users.

If they choose to manually add a hostname to the config, then so be
it.  The leafnode server shouldn't bork just because it gets checked
several different ways.

Hmm.  I hadn't noticed that IP.  Weird.  This machine does have 2
interfaces - one for the connection to router (192.168.1.10) and one
for LAN (192.168.0.1).  The armadillo hostname has never been
manually associated with 192.168.1.0 network.  I had it in hosts as
192.168.0.1!  Must be the /etc/hostname playing up?

$ cat /etc/hosts.allow

leafnode: 127.0.0.1 192.168.0.1

Anyway, changed /etc/hosts to the armadillo entries on 127.0.0.1 and
it's working now.

Thankyou so much for your time and advice Matthias.  Your quick
responses and patches etc are much appreciated, and I am sure by
others (not just me).
