Activating Spam Filtering for Your Account
Spam filtering is turned on by default for accounts created after April 1st, 2008 but not on older accounts.
You can turn mail filtering on by running the follow command (from a terminal window) on ms:
activate-mail-filter
Alternatively, you can edit your .procmailrc file manually and add this line at the top:
INCLUDERC=$RHPCS_MAIL_CLEANER/procmailrc-clean
All filtering activity will be recorded in the file .procmail-log in your home directory.
