My SpamAssassin daemon is not flagging as much spam as I would like (but it is flagging some), so I took a sample message which had not been flagged, and ran it thru SpamAssassin at the command line. The results are entirely different for the same message (see below).

  • What should I look for in the configuration which might cause this?

  • How can I temporarily enable debug for spamd (Ubuntu 16.4, not using amavis)

Results via spamd:

X-Spam-Checker-Version: SpamAssassin 3.4.0 (2014-02-07) on myhost
X-Spam-Status: No, score=-1.1 required=2.0 tests=BAYES_00,RDNS_NONE,
    SPF_HELO_PASS,URIBL_BLOCKED autolearn=no autolearn_force=no version=3.4.0

Results via command line:

Without the actual configuration it's hard to say what could be wrong. This might be some permission issue, for example if the spamd is running as a user that doesn't have permissions to read ~/.spamassassin/user_prefs and, therefore, only runs the tests and scores configured in /etc/spamassassin/local.cf.

How can I temporarily enable debug for spamd?

Run it with spamd -D (i.e. --debug for printing debugging messages). You can compare the output to the output of spamassassin -D to see what's the difference.
