Aaaarrrghhh. I suspect I'm shouting into a void here, and it's been said
many times, but if there happen to be any lurkers using either Exim 3 or
4, with Nigel's "block executable attachments" filter, please stop, now!
You are generating spam to the entire world (I see your spam every day),
and almost certainly giving Exim an undeserved bad name into the bargain.
And aside from that, it's unreliable and "bad" mail WILL slip through it.

Please don't. The script is old and generates spam. There are much better
solutions with Exim 4. Use Exiscan instead.
http://duncanthrax.net/exiscan/ . You can do attachment blocking,
reliably, reject at SMTP time and *much* more, such as easily hooking in
SpamAssassin or a proper virus scanner. Read this if you need some help
getting started:
