    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 πŸ™‚

            @jwildeboer It's probably not related to you reporting them. Most often I'm too lazy to do that and I still get the same kind of spam recently.

              @julian I tracked deep enough to make the connections between reports I made, the sending domains of that spam, the domains used for these support tickets etc. I am 90+% confident it is more causation than correlation.

                @julian But I also wanted to document in the open how these support ticket spams work. Regardless of the why. The forwarding address is in all cases a google account, so it comes in via google mail servers. I report these domains to google and that's all I can do. The spammers know that Google typically doesn't care, especially when the domains used expire in a few days/a week.

                  @jwildeboer Google Account as in Gmail? I'm getting lots of spam forwarded through Google Groups (maybe I should just start filtering that).

                    @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?
