Whenever I subscribe to a mailing list, I set up a majordomo list on our
machine here and send the subscribe to that list name. This allows me to
provide local distribution and local archives easily.
How is the majordomo program supposed to check to see if the user-supplied
address is valid, particulary if VRFY and EXPN are turned off at the
subscribing site? It could never check in cases where e-mail goes through
Real-time verification of e-mail addresses probably wouldn't work more
often than it would given the variety of methods of mail delivery.

Government spending? I don't know what it's all about. I don't know
any more about this thing than an economist does, and, God knows, he
doesn't know much.
