Fighting spam

How Horizon Hosting helps keep unwanted email out of your inbox.

What can I do to combat spam?

Most of the work is already done for you. Horizon Hosting checks incoming email on our mail servers, before it reaches your phone, tablet or computer.

Our filtering combines three established protections:

DNS blocklistsChecks known sources of unwanted mail.
GreylistingChallenges suspicious automated senders.
SpamAssassinAssesses message patterns and content.

How do I turn it on?

Spam filtering is included with every Horizon Hosting subscription. Open your control panel, select your mailbox and enable the spam filter.

  1. 1
    Enable filtering

    Start by marking suspected spam rather than deleting it.

  2. 2
    Review your results

    Check that legitimate messages are still arriving normally.

  3. 3
    Choose what happens next

    When you’re comfortable with the results, you can automatically delete identified spam.

Our recommendation

Don’t enable automatic deletion straight away. Marking spam first makes it easy to spot any false positives—legitimate email mistaken for spam.
