A lot of places and mailers _do_ check the inbound address for
correctness, but there's nothing stopping me from being on the machine
I claim I am, but asking for mail that the other end hasn't gotten
around to delivering yet -- if the load is high enough on ucbvax, and
mail comes in that needs to go to xx.lcs.mit.edu, it will get queued
...  in the interim, i go to xx.lcs.mit.edu and telnet to port 25 on
ucbvax and give a turn ... sendmail on ucbvax says "oh, ok -- here's
your bloody mail" and I get it all ... I repeat -- not _too_ cool.
