is there a way to set up a hook of some sort, either at the whatnow

don't succeed?
i use a wrapper script for my editor in mh, and the script
prints warnings regarding the draft when the editor exits.
If that script exits with non-zero status, then comp, etc.,
should not send, and terminate with a message.
it checks for things like a missing To: header at all, or if the
From: header looks like my home address but the To: header looks
like a work address -- that sort of thing. when vi exits,
and i'm back at whatnow, i get this:
WARNING: missing or empty 'To:' header....
What now?
and that's great, when i'm fully caffeinated and am actually paying
attention to what's on the screen.
i'd like to elevate at least some of those warnings to fatal errors --
i'd like to not be able to send the message until i fix the problem.
how might i do that?
If I understand correctly, you're doing something like:
comp -editor sanitychecker
where sanitycheck is of the form below. Or do you get
to whatnow some other way?
David
#! /bin/sh
<sanity checks>
if <sanity checks succeeded>; then
exec whatnow -editor $EDITOR "$mhdraft"
else
echo sanity checks failed
exit 1
