When spammers don't like you reporting their spam, they will:

- set up a forwarding email address on one of their servers with good DKIM/SPF/DMARC, typically on a domain that will expire soon
- Run a script that spams hundreds of support addresses/web forms with nonsense content using that forwarding address
- Forward all the confirmation receipts to your email address

That stuff is easy to block, but can be quite a nuisance to the affected support teams.

@jwildeboer @homelab That is sad indeed. One email address per service might be good to avoid the problem and just shut that one down but... scary to organise , right?
Why can one not set up email with a key system so if sender does not have the public key it goes into spam?
