For Web Hosting customers with a IONOS email address
Do you often receive unsolicited spam or promotional emails from a specific email address? With the blacklist function of IONOS WebMail, you ensure that these emails are filtered directly into the spam folder and no longer appear in your inbox.
Log in to IONOS WebMail.
Click the menu icon (System Menu) and then click Edit Settings.
Click on E-Mail > Anti-SPAM, then under "Personal lists" under "Blacklist" on Display and then on Add.
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.
