Apart from the TLS/SASL bits the main.cf for all these headless
systems is:-
mydomain = zbmc.eu
myorigin = $mydomain
relayhost = [mail.gandi.net]:465
luser_relay = ch...@isbd.co.uk
local_recipient_maps =
#
#
# We don't accept any incoming connections
#
mydestination =
inet_interfaces = loopback-only
So myhostname isn't explicitly set.
Having 'mydomain = zbmc.eu' worked until now because the systems in
question were on a LAN which is zbmc.eu. However I'd now rather like
to use the same main.cf on some systems which aren't on the same LAN.
It does need to be set so that one can tell easily where messages come
from.
