    Thanks Dominik, that fits with the way it worked best during my
    experimentation.
    The unix socket is a good idea, I had wondered how to get round that.

    It turns out that my issue was a complete newb one - I used tcpdump from
    within the guest and found the packets were reaching the OS after all.
    I had used the CLI to add rules to iptables on the guest for the mail
    server, not realising that it was dumb and was appending the rules AFTER
    the default-supplied REJECT rule. After re-writing and reloading the
    ruleset, all is now well.

    Thanks for the assistance and the tips.
