Activate Anti-SPAM Settings in Webmail

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.

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 analyzes 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.

In the following article we describe how to open and move emails that have been classified as spam by Spam Protection.

Opening and Moving Emails Classified as Spam

In the following article we describe how to specify email addresses from which emails should be automatically routed into your inbox:

Always Allow Emails from Specific Senders in IONOS Webmail

If you check your email through IMAP, the Spam folder is automatically displayed in your email program.

If you check your email through POP3, you can only access the Spam folder in Webmail. In this case, access is not possible with an email program such as Microsoft Outlook.

If you check your emails through POP3 and want to access your spam emails in your email program, you can have the spam emails you receive routed into the inbox. To enable this feature, in Webmail, select the Spam Protection setting Custom and in the Filter Settings section, enable the option to Send with note [SPAM?] in subject (does not work at the same time as the Text Pattern Profiler).

To specify the email addresses from which you do not want to receive email, in the Blocked senders: area, click Show. Then click Add. Enter the email address you want and click Add again.

In the following article we desribe how to disable the spam report.

Disable Spam Report and Configure Custom Spam Protection Settings.

If you enable the Spam Protection setting Low, Medium or High, you will receive a daily spam report by email. If you select the Custom option, you can select this option after enabling the Move to Spam Folder setting. To receive the spam report, enable the Send Spam Report Daily option.

The Spam Report lists a summary of a maximum of 20 emails delivered to your mailbox within the last 24 hours.
