It does, but the source of my problem was that I forgot that it was tested
twice (address, then host name).  So when the address is
[EMAIL PROTECTED], [EMAIL PROTECTED] doesn't match the address
(good), but it /does/ match the host name (oops).  So the rule fires anyway.

Hmmm.  OK, thanks for that - I'll go and do some more reading and pondering.
