Dear Martin. Welcome to our daily world, we are sending all spamming ips to the blackhole in our router. Kind regards.

It seems to be hosting a customer who sends spam and uses one of my domains as sender. I got the information via DMARC, RFC 7489 with several mails. This provider has an abuse email address. After I contacted them, they analyzed my domain, complained about the header of the automatic DMARC e-mail from mail.ru [http://mail.ru], because there an internal host distributes it and uses an internal IP address 10/8 according to RFC 1918 and so on. Apparently one does not want to do anything and requests one of these e-mails classified as spam sent to @mail.ru. But this is not provided for in the DMARC protocol, which the provider does not 'believe’. This means I continue to receive emails from Russia telling me that my domain is being used by their host to send spam. And the provider writes me many e-mails telling me that I have to provide correct facts and that nothing else will be done. Because DMARC emails are not facts and cannot be used as evidence. Do you have any idea how to deal with this? I have received 11 DMARC emails from mail.ru [http://mail.ru] regarding this host. I have attached last one here with header: Return-Path: <dmarc_support at corp.mail.ru [mailto:dmarc_support at corp.mail.ru]> Delivered-To: mnin at mnin.de [mailto:mnin at mnin.de] Received: from mail.mnin.de ([xxxx]) by mail.mnin.de with LMTP id yedWJNMKx14sDAAAuS6XVA (envelope-from <dmarc_support at corp.mail.ru>) for <mnin at mnin.de>;
