Question
What files should be used to configure custom SpamAssassin rules in Plesk for Linux?
Answer
Custom SpamAssassin configuration can be set in the following files:
/etc/mail/spamassassin/local.cf - for the server-wide configuration.
/var/qmail/mailnames/example.com/john_doe/.spamassassin/user_prefs - for individual users configuration.
For more information on advanced SpamAssassin configuration, refer to the Advanced Administration Guide, Spam Protection for Linux, and SpamAssassin documentation.
Note: Adding custom configurations in these files can be overwritten by Plesk update and other actions related to these files.
For example, changing settings at Tools & Settings > Spam Filter page.
