I just spotted a strange mailop message... it had no FROM and no SUBJECT
line in the message header. (not even a blank subject line in the
header, just no subject line at all) If the sender has been having
problems - if their system is doing stuff like that, maybe that is part
of their problem. (I don't know... just speculating) Or could that have
been a mailop list server malfunction?
NOTE: In the content of the message, it discussed another message, and
gave an example of a header. I'm NOT talking about that message being
discussed - I'm talking about the actual message received from mailop.
