Your post prompted me to try this in a redirect router, since it
sounded trivial (no need for the exiscan patch). I must be missing
something obvious, since I can't get it to work. I added this router
definition above the normal alias and local delivery routers:

check_exe:
  driver    = redirect
  no_verify
  data        = ${if match { $message_body } \
        { "TV[nopqr][A-Z]...[AB]..A.A....*AAAA...*AAAA" } \
        {exe} fail }


I left off the ^ since in $message_body newlines have been converted
to spaces. message_body_visible is set to 2000, which is more than
enough to include the first few lines of the attachment in the test
message I tried. pcretest says the pattern matches the text
cut&pasted from the message (with newlines converted to spaces).

But the router doesn't handle the message. I feel stupid, what am I
missing?
