Saving SpamAssassin user prefs in database -- Am I missing a step? (solved)

🛈 SYSTEM INFORMATION
OS type and version Debian 10
Webmin version 1.984
Virtualmin version 6.17-3

Edit:

Storing preferences in a database was not the issue.

The problem is that USER_IN_WHITELIST is just another SpamAssassin test with an associated weight rather than an instruction to bypass spam filtering. This is a good thing, because even whitelisted addresses can be forged, so there should still be a threshold above which they can be flagged as spam.

If a user is receiving non-spam messages that nevertheless score high enough that they are not sufficiently offset by the USER_IN_WHITELIST score, then you can either decrease the overall spam score threshold, which may allow more spam through from all addresses, or change the weight of the USER_IN_WHITELIST test, e.g. by inserting something like score USER_IN_WHITELIST -10.0 in either the system-wide .cf file or an individual user’s .cf file.

Keep in mind when testing with GTUBE that SpamAssassin has a specific test for that (named GTUBE) with a weight of 1000!


Original problem:

I’m trying to store SpamAssassin user preferences in a SQL database, but the database preferences seem to be ignored. Here’s what I have done:

  • Created a database for SpamAssassin settings.
  • Created userpref table:
	CREATE TABLE userpref (
		username varchar(100) NOT NULL default '',
		preference varchar(50) NOT NULL default '',
		value varchar(100) NOT NULL default '',
		prefid int(11) NOT NULL auto_increment,
		PRIMARY KEY  (prefid),
		KEY username (username)
	);
  • Configured database in Servers > SpamAssassin Mail Filter > SQL and LDAP Databases.
  • Configured database in Webmin > Usermin Configuration > Usermin Module Configuration > SpamAssasin Mail Filter.
  • Edited /etc/default/spamassassin and added -x -Q to OPTIONS command line.
    • systemctl daemon-reload
    • systemctl restart spamassassin
    • Confirmed with systemctl status spamassassin that the service started with the -x -Q options.
  • Created a mail user in Virtualmin.
  • Logged in to Usermin as new user.
  • Whitelisted an email address in Mail > SpamAssassin Mail Filter > Allowed and Denied Addresses.
  • Confirmed that the whitelist entry exists in the database table.
  • Sent message containing GTUBE test string from whitelisted email address.
  • Message was delivered to user’s Spam folder.

Is there something I’ve missed?

EDIT: I’ve just noticed that user_scores_dsn was not set in /etc/spamassassin/local.cf. I set it appropriately for my system to DBI:mysql:spamassassin:localhost and restarted the spamassassin service, but this made no difference.

EDIT: According to the spamassassin service journal, spamd read scores from SQL and flagged the message as spam, and the spamd result line includes USER_IN_WHITELIST:
