Updated 2 weeks ago by Theo Chu

Spam is everywhere nowadays and it seems impossible to escape from it. While you can't prevent spam entirely, here are some solutions to reduce the spam oyu may be receiving in your inbox.

Spam Assassin

One of the easiest solutions, Spam Assassin analyzes and identifies spam based on message headers as well as the content in the emails using it's automated filtering system. Each email is scored by an algorithm to decide if the incoming email is legit or spam. If you're scared of losing important emails that could potentially be improperly marked as spam, you can opt to move all your spam mail into a spam/junk folder. This way you can sort through it yourself to make sure no crucial emails were tossed away. To enable Spam Assassin, simply go to the Mail section of cPanel, and click on the SpamAssassin icon.

Setting Up Email Authentication

There are two ways to set up email authentication. The first is a DKIM (Domain Keys Identified Mail), the second is the SPF (Sender Policy Framework). Both authentication features are essentially used to determine whether or not the email was sent by a trusted user.

How To Enable DKIM

DomainKey's main function is to insert digital signatures that can be verified via public keys published by the DNS. This way, you know for sure that the emails are reaching the listed senders and have not been modified during its transit to them. To enable DKIM:

  1. Click on the Mail section.
  2. Click on Email Authentication.
  3. Click enable under the DKIM section.

How To Enable SPF

One of the main functions of the SPF feature is to prevent any spammers from impersonating you, and forging messages that appear to come from your domain. This is more commonly known as spoofing. This functions adds IP addresses to a list that are authorized to send messages from your domain. To enable SPF:

  1. Click on the Mail section.
  2. Click on Email Authentication.
  3. Click enable under the SPF section.

If you would like to have more control over who is able to send mail from your domain, you can add or remove additional IP addresses or mail servers to your liking. You can do this through these following steps:

  1. Click on the Mail section. Click on Email Authentication
  2. Pick from the options such as adding additional hosts, servers, IP addresses, or include lists to the SPF configuration. Click Add.
  3. Pick from the options such as removing hosts, servers, IP addresses, or include lists to the SPF configuration. Click Remove.
  4. Click Update.
