Actually, no. The sender-blacklist-* and recipient-blacklist-* filters operate
on different data from the header-blacklist-* filters. The reason is because
the sender and recipient addresses are given during the SMTP protocol and
aren't part of the message itself -- the addresses you see in your mail client
are the From and To entries from the message header. The first paragraph here
explains in a little more detail:
http://www.spamdyke.org/documentation/README.html#REJECTING_SENDERS
Put another way, the sender address doesn't have to match the "From" address
visible in the mail client -- well-behaved mail clients make them the same, but
that's a courtesy and not a requirement. The Reply-To address is part of the
message header and, again, is only a convention used by well-behaved clients.
If you've ever been Bcc'd on a message, you've seen this in action -- the
sender's mail client gave your address as a recipient but didn't put your
address on the "To" line in the message header.
