i agree that this can taken up at a different level (read as catbert), i
also think that poor passwords are also responsible for sender spoofing.
We had a case a year back, where a "secure" SMTP server was used for UBE
(via a korean IP), using authentication that was quite easy to guess
(password = username). Now we now enforce stricter passwords ;-)
