At a guess, your problem is you have not configured the internal_networks and the trusted_networks options in your local.cf file, and Spamassassin is guessing these values (it will if you have DNS available), and your server is behind NAT, which makes the guessing code work poorly. Either: Set score ALL_TRUSTED 0 in your local.cf to disable the test (do not edit the files in /usr/share/spamassassin/ or else you will lose the changes in an upgrade.) or else: man / perldoc Mail::SpamAssassin::Conf and configure the internal_networks and trusted_networks settings accordingly in your local.cf. From memory, something like: internal_networks 127.0.0.1 192.168.1.0/24 trusted_networks 127.0.0.1 192.168.1.0/24 There are still a couple of bugs open against the ALL_TRUSTED issues which you may care to read as well http://bugzilla.spamassassin.org/buglist.cgi?query_format=specific&order=relevance+desc&bug_status=__open__&product=&content=ALL_TRUSTED Regards Daniel
