Hello!

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.
