Mark Emails from Certain Addresses as Spam in WebMail

For Web Hosting customers with a 1&1 IONOS email address

Do you often receive unsolicited spam or promotional emails from a specific email address? With the blacklist function of 1&1 IONOS WebMail, you ensure that these emails are filtered directly into the spam folder and no longer appear in your inbox.

 

Step 1

Log in to 1&1 IONOS WebMail.

Step 2

Click the menu icon (System Menu) and then click Edit Settings.

Step 3

Click on E-Mail > Anti-SPAM, then under "Personal lists" under "Blacklist" on Display and then on Add.

Step 4

Enter the email addresses you want to blacklist and click Add. Repeat the process for additional email addresses. The changes are saved automatically.

Hint: You can also define complete address ranges here. For example, if you want to filter all emails in the @domain.com address range as spam, enter this in the *@domain.com format. The asterisk serves as a wildcard.
