Hi, Russell.
If you check the rule itself in 20_dnsbl_tests.cf you'll notice the
-notfirsthop part of the argument to check_rbl_txt().  This tells
SpamAssassin to check all hops except the first one for this match.  As a
result it shouldn't match people sending email through their ISP's mail
server, though I too am seeing a problem with some emails matching the
DYNABLOCK rule despite being sent through their ISP's mail server.  I had to
go ahead and rescore the rule down to .1 because it was causing too much
trouble (but I do want to see when it matches for diagnostic purposes).

Subject: [SAtalk] RCVD_IN_DYNABLOCK

I just upgraded to 2.60, and have noticed an increasing number of
false-positives because of a RCVD_IN_DYNABLOCK match.  I've double checked
the headers, and the mail servers delivering the mail are not in dynablock.

Perhaps I'm not seeing this correctly, but wouldn't this mean that anyone
sending mail out through their ISP's mail server that keeps the Received:
headers would also end up being tagged?  That doesn't seem to be very
useful, especially with a default weight of 2.5points.
