Yes, I meant deferring.  But in my case, it was continually defering until
I bothered to check the logs, which to a newbie looks like rejecting.  After
I commented the line out and restarted exim, the mail came through fine.

Maybe.  But I know some list maintainers that get cranky if they notice email
that is stuck in their queue ;).

That's just it.  I _did_ ask for spam checking.  I started spamassassin and
then uncommented that line.  What I didn't expect is for it to defer email
when I don't even have a virus checker installed.  Call it a newbie mistake.

Sure, adding that to the comments would be fine IMHO.  That way newbies will at
least know what happens when they don't have spamassassin or a virus checker
running, and how to work around it if they don't want to do one or the other.
