Your Name Here spam filters are designed to be configurable to match the needs of your individual mailbox. As well as blocking email senders, you can also add them to white list to ensure you receive emails from them, set a tolerance level and decide exactly what to do with emails that are recognised as spam.

The steps below will help you make the most of your spam filter:

Step 1.

Log in to your control panel and click on the mail tab:



Step 2.

Step 3.

Click on the Spam Filter tab and this will give you your spam filter options.Ensure the tick box is checked to switch on the spam filtering. Then you can choose how to handle spam. The above option moves the spam into a spam folder. As mentioned, using an IMAP account you can further train the spam filter to make it pick up on all emails you want treated as spam.



Step 4.

Click on ‘Show Advanced Settings’ and this allows you to enter safe email addresses into a ‘Whitelist’ and spam addresses into a ‘Blacklist’ It also explains the Filter Sensitivity setting which you can make more sensitive or less sensitive depending on whether or not all spam mail is being flagged:

Make the most of your Spam Filter

The fight against Spam is a significant challenge that you face daily, and it continues to be  one of the biggest problems on the Internet. Spammers are clever and they will continually conjure up new ways to bypass spam filters, so unwanted email will always be there, but you can dramatically reduce the amount of spam you receive if you use your Spam filter correctly.

Spam Assassin     spam

At Your-Name Here our choice of default Spam Filter is Spam Assassin.

SpamAssassin uses a variety of spam-detection techniques, that includes sophisticated scoring filters, Bayesian statistics, external programs, blacklists and online databases.

Used correctly, it can be a very effective deterrent against unwanted email.

How to configure Spam Assassin.

  1. Firstly login to your Plesk control panel.
  2. Click on the Mail icon under Services.
  3. Click on the email address you would like to configure settings for.
  4. Then click on the Spam Filter icon in the Tools section.
  5. In the Preferences section, you firstly set the score/tolerance level that email must hit before it is recognised as Spam. Each email is  scored between 1 and 10 . As an example, if you were to receive an email with the subject ‘Buy Viagra Now’ that would score 8 or 9 as it is obviously Spam. The default setting is 7, which is usually a good place to start, but if you feel Spam is not being recognised enough, you just lower it to 6 or 5 and see how it goes.
  6. The What to do with Spam section gives you the choice to remove Spam automatically when it comes to the mailbox, or still deliver the email and mark it as xxxSpamxxx. If you want to include into the subject line the number of points that messages score, type _SCORE_ in this box. This will help you determine the best score setting to have.
  7. Next is the Blacklist section which allows you block specific addresses or domains that you do not want to receive mail from. You can add muliple entries, seperated by a tab, a colon or a comma. If you do not want to receive anything from any address at a particular domain you can use * as a wildcard. Just type * and any user at that domain will be blacklisted.
  8. Similarly there is also a Whitelist section. If you want to be sure you do not miss any emails from specific senders, you can add multiple entries to your Whitelist in the same way.
  9. Click on the Training tab to improve accuracy of spam detection by training the spam filter on the e-mail messages that you have in your mailbox. Simply highlight an email and click on ‘It’s Spam’ or ‘Not Spam’  Once finished with training, you can remove spam e-mails from your mailbox using your e-mail program or Horde IMP Webmail interface.
  10. Once finished with your spam filter settings, remember to click the ‘Switch On’ icon, and then click OK.

That’s it! Your Spam filtering is now enabled and set to your specific requirements. The settings can be modified at any time in the same area of your Plesk control panel.
