Activate Anti-SPAM Settings in Webmail

For Mail Basic and Mail Business

With Anti-Spam you can prevent or limit the delivery of spam emails. Anti-Spam automatically scans all incoming emails in your mailbox. Depending on the configuration you choose, spam emails are either moved to the Spam folder or they are sorted into the Inbox with the note [SPAM?] in the subject.

This article explains how to:

  • If you have an email box set up at IONOS, then you can configure Anti-Spam directly through Webmail.

Open Anti-Spam settings

To open the Anti-Spam settings:

  • Log in to Webmail.

  • Click on the cogwheel symbol in the blue main navigation at the top right.

  • Click Anti-SPAM in the navigation bar on the left under Email.

  • Now you have the option to choose predefined spam protection levels or to configure custom spam protection settings.

Configure Custom Spam Protection Settings

When you configure custom spam protection settings, you should enable the following options to ensure maximum protection against spam emails:

Letterhead Analysis:  Letterhead analysis allows you to choose the sensitivity of spam detection according to your needs.

The detection mechanism checks the headers of the received emails. If a received email contains flags that indicate spam, points are awarded for this. These points form the SpamScore. Based on the SpamScore, your received emails are classified as spam or not spam. Criteria are e.g. certain words, a wrong date or an IP address known to send spam.

You can choose between Low, Medium and High settings.

  • Low: Emails sent or forwarded from IP addresses that have been conspicuous for spam activity are marked as SPAM.

  • Medium: In addition to the criteria of the Low level, static rules are applied, additional block lists are queried and checksums are created and checked.

  • High: In addition to the Low and Medium level criteria, a lower threshold is set to classify spam.

Text Pattern Profiler: The text pattern profiler analyses emails located in the spam folder and can improve the spam detection rate.

Enable Anti-SPAM For Known Spam Servers: This setting appears when you select the Custom spam protection level. If you enable this option, typical spam servers will be detected. In addition, all emails sent to your mailbox from these spam servers will be moved to the Spam folder.

Enable Anti-SPAM For Bulk Mail: This setting appears when you select the Custom spam protection level. If you enable this option, bulk mails with identical content will be detected and moved to the Spam folder.

Safe Senders: In this section you can specify any email addresses from which you want to receive emails.

Blocked Senders: In this section you can specify any email addresses from which you do not want to receive emails.
