By configuring Spam Assassin, you can automatically detect unwanted emails and tag them with a clear subject line. Spam emails can clutter your inbox and reduce productivity.

This guide explains how to set up Spam Assassin spam filters to mark suspicious emails with ***SPAM***.

Steps to Configure SpamAssassin

1. Access SpamAssassin Directory
   Go to the .spamassassin directory of your user:
   cd /home/username/.spamassassin
2. Edit User Preferences

   pico /home/wwwmfm/.spamassassin/user_prefs
3. Set Required Rules
   Add or update the following lines:
   required_hits 1
   rewrite_subject 1
   rewrite_header Subject *****SPAM*****

Please Note:

• required_hits 1 >> Sets the spam score threshold to mark an email as spam.
