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 so you assume they do this out of pure revenge? I had this in the past and wondered what was happening. But I never reported anything, I think 🤔

@heine I've been in the business of spam fighting since more than 20 years. Yes, this is how they act. Childish shit to annoy people like me.

@jwildeboer @heine
i didn't report any spam and i think nearly all Domains on my Mailserver get this "spam"
One time when i got bombed with that stuff, there was one paypal-email and an order in it, which used my Name and bank details (50€ for honey).
You can pay with a PayPal guest account using a bank account nr.
I had to cancel the order and deal with PayPal.

How do you block it?
