Our servers support using custom Spam Assassin configuration files, you can use this tool to generate the new config file. Once you generate it, save it as /home/cpuser/.spamassassin/user_prefs on your account.
You can also manually edit this file, a few of the operatives are:
- required_score - Defines the required score for Spam Assassin, 5 is default, 1 is the most strict (lets the least amount of spam though, may filter too much), 10 is the least strict (lets the most amount of spam though, may filter too little).
- whitelist_from - Allows email from this address or domain, syntax is "whitelist_from user@domain.com"
- blacklist_from - Denys email from this address or domain, syntax is "blacklist_from user@domain.com"
