Wow, that's immensely ugly and runs contrary to every content scanning
tutorial out there, including the examples in the Exim manual.
Dean, is your config unusual in any way or, at a glance, are many people
likely to hit the case of having an undefined $spam_score_int in the
same way you have?
While Exim is very flexible (Turing-complete IIRC?), it's not supposed
to be a programming language per se, so I think the old ("buggy")
behaviour of implicitly equating null/undefined and zero was helpful in
the context of writing readable configs. I think conditionals are
complicated enough to beginners without having to explain the above
abomination...Philip?
