    Nobody prohibited for example to load netfilter module, which
    will accept _all_ the packets to port 6666 as destined locally. :-)

    However, the statement is wrong: SIOCGIFCONF really returns
    all the addresses which are local "officially". If MTA
    fails to deliver mail to "unofficial" address, it is problem
    of adminstrator, which either should not create such addresses
    or use proper MTA, which has enough reach set of rules, controlling
    delivery, sendmail, for example.
