Spam Assassin is an intelligent email filter that uses a diverse range of tests to identify unsolicited bulk email, more commonly known as spam. These tests are applied to email headers and content to classify email using advanced statistical methods. Spam Assassin is developed by Apache; the makers of the #1 web server software on the internet with almost complete market share control in the Linux website hosting market.

Go to the webmail control panel (instructions in the box below):

• Click on mail
• Click in Mail Filters on the sidebar
• Click on Spam Filtering  to view the settings.
• Check the box labeled subscribe
• Choose the level of spam filtration you want. The preset filters are great for basic spam protection.

Email that is identified as span is filed into a "Junk Email" folder.   HotDoodle will empty this folder from time to time if it fills up.

Blacklists/Whitelists

Blacklists keep unwanted email addresses from sending mail to you. Whitelists do the opposite. They always allow mail from the addresses listed, regardless of spam rating. Rules, or addresses set in whitelists always work, before blacklists, so if an email address is listed in both the white and black list, it will still deliver the mail.

• In the “whitelist” section, simply type in an email address you want to bypass the mail filters and click Add to whitelist. You can also remove an address from the whitelist by checking the box next to the address and click Remove from whitelist.
  
  
• In the “blacklist” section, type in an email address you want to block and click Add to blacklist. You can also remove an address from the blacklist by checking the box next to the address and click Remove from blacklist.   Do not bother trying to list ordinary spammers in blacklists, they change email addresses very frequently. Instead use blacklists for ordinary but confused organizations such as a school newsletter that will not let you unsubscribe.
