AFAIR we've had this before and the (Tim Jacksons?) remedy was to set
the SA code and ACL to something a spammer wouldn't reckon with. Like
X-Wibble-Wobble or whatever.
However, as long as I've been following this list, no-ones ever
mentioned any spammer actually having done this. Their spam software (up
to now) simply isn't made for every eventuality in every anti-spam utility.
Best,
Tony
