An Anti-Spam gateway #8: MySQL and SpamAssassin

(NOTE: this is part of the “An Anti-Spam gateway” series)

Thought I’d forgotten about this one, didn’t you?

Ready to make SpamAssassin actually use MySQL for the bayes database?

Start by creating the database itself:

mysql CREATE DATABASE bayes; GRANT ALL PRIVILEGES on bayes.* TO bayes@localhost IDENTIFIED BY 'password'; GRANT ALL PRIVILEGES on bayes.* TO bayes@10.0.0.1 IDENTIFIED BY 'password'; EXIT

changing password to something else, of course

Next, I know you’ve already installed SpamAssassin using CPAN, but go to www.spamassassin.org and download it manually; you’ll be needing a file from the distribution, and while it should still be in /root/.CPAN, it’s simpler this way. Uncompress the .tar.gz and go to the sql/ directory. Then type:

mysql -u bayes -p < bayes_mysql.sql

It’ll ask for a password, which is the one you used when creating the database.

Now, edit the file /etc/mail/spamassassin/local.cf. Add the following lines:

bayes_store_module Mail::SpamAssassin::BayesStore::MySQL bayes_sql_dsn DBI:mysql:bayes:localhost bayes_sql_username bayes bayes_sql_password password

(again, replace password with the proper one.)

SpamAssassin is now configured to store bayes data on MySQL. Wasn’t too hard, was it?
