I'm running SpamAssassin 2.60 on a public IP (not NATed) and none of the
-notfirsthop rules (including RCVD_IN_DYNABLOCK) have worked correctly for
me, either.  For reference I'm also running Sendmail and Spamass-milter
0.2.0.  Here are the headers from an email that *should* have matched the
rule:

When querying Dynablock:
katie> host 0.27.46.68.dynablock.easynet.nl.
0.27.46.68.dynablock.easynet.nl is a nickname for
dsl-cable-dhcp-dialup.ip.dynablock.easynet.nl
dsl-cable-dhcp-dialup.ip.dynablock.easynet.nl has address 127.0.0.2

While in this case it fails to detect that the email originated from a
dynamic IP, I have other cases where mail sent through Earthlink's SMTP
servers are falsely detected:

Any thoughts?

This could be an example of bug 2537... note that his IP is a non-routable
one..

Pedro, did you set your trusted_networks variable in your local.cf? since
your localhost is using a 192.168.*.* IP address SA cannot automatically
infer which relays are trusted.. this causes the unexpected side-effect of
causing SA to check _every_ IP address against dynablock.


http://bugzilla.spamassassin.org/show_bug.cgi?id=2537

add this to your local.cf and see if it fixes your problem:
         trusted_networks 192.168.2.125/32
