  Okay, I won't.  But I will point out that it seems really silly.
Why bother with the whole user-identification scheme involving passwords
and whatnot, if the system really only cares about the e-mail address in
the "From:" field?

  And a follow-up question: What if I send e-mail from
"ajo@andrew.cmu.edu" instead of "ajo+pbmserv@andrew.cmu.edu"?  Will it
still get eaten, or will it be okay?  And simply for curiosity's sake,
what if I send e-mail with "gobbledygook@google.com" in the "From:" field?

  I don't know what that means.
