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.

I guess they will also use the support forms to try to subscribe me to whatever marketing stuff from there.

So I look forward to interesting messages from Bavarian restaurants, Austrian doctors and swiss lawyers :)

So I guess for the next few days you can send an e-mail to [email protected] and it will reach me ;)

@jwildeboer I didn't report any spamming, still one of our email addresses started receiving all those autoresponders directed at
[email protected]
I saw that this domain shall expire at the end of the month; hopefully theses emails will stop soon after!?

@Tatone Yep, they will. And then they will set up these forwarders again on another domain that will soon expire. And the next one. And the next one.
