Mail2.ecloud.global does not work with freenet.de

[tcecyk]

Problem with sending mails to e.g. freenet: 550-Inconsistent/Missing DNS PTR record (RFC 1912 2.1)

the ptr really is inconsistent. The subnet address d00b within 2a01:4f9:4b:5387::2/64 is pointing to mail.ecloud.global instead of mail2, where the first address within that /64 range is pointing. I think it’s an oversight. Depending on product, it isn’t easy to decleare a ptr for a whole cidr. I guess I’d fix the mis pointer at :d00b::2 if its a stable address. You can forward your mail response to postmaster@ecloud.global - very likely it directly reaches a person doing mail+dns

@arnauvp I think you’d need to review the ipv6 ptr on mail2

@Aki if nothing happens, either the postmaster mail in the linked answer or forward this forum link to helpdesk@e.email
