Hi delpantalone,
Thank you for your feedback.
Unfortunately, it is not possible to create a rule to avoid spam ending in your inbox as they reach the server.
We suggest you to click on “Block” on the top right of the email. That will add the sender to the blocked senders list (in Settings) and transfer the email directly in the trash.
You can also tick the option “Empty trash of all Bluewin email accounts automatically on logout” by clicking on “Settings” > “Email”. Emails from blocked senders in the trash will be automatically deleted.
Hope it helps!
Kind regards,
