Maybe, maybe not.  Why can't listserv just check to see if all message
lines are valid listserv commands?  If just one line is found that is
not a valid listserv command, then the whole thing is mail.  This
would take care of 99% of the bogus things that are posted to lists by
ignorant (read, uneducated) users.  (I can hear the objection now...
"it'll mean having to scan the message body twice."  Only seldom.
Normally, the command files will go directly to listserv, not a list,
mail files will usually be detected as such on the very first line.)
 
Of course, if any change of this type were to be made to listserv, I
think listserv should send an admonishment back to the sender telling
the right way to do it.
