Wie kann ich verhindern, dass unerwünschte Mail auf meinem Computer landen?

In principle, the Internet now unites good and bad people…

Most likely, you prevent mail from being sent to your own computer by not using a local mail client (such as Outlook or Thunderbird), but by running your mails directly on the provider server. Each client first uploads mails to the computer, only there they sort out the spam filter, i.e. into another folder.

Spam filters are flawful, but important mails can already land in the spam folder.

A better, though more complicated, solution would be to use several mail addresses, e.g. do not use its “right” address for orders, etc.
