Hi If what you're asking is if we're publishing DMARC records for all our customers domain, then the answer is both yes we do, and no we don't. We publish DMARC if the customers have added DMARC themselves (we're a shared hosting provider. Customers can add the DNS records they wish to have). We do not automatically add DMARC or SPF records to any domain as that will affect email delivery if they use any other servers to send email (as many do). But we do publish DKIM keys and DKIM sign as there are no adverse effects from that.
The domains affected by the "Too many messages" issues we see are exclusively domains that have either: - no SPF records - SPF records that does not include our mail servers - broken/invalid SPF records The defer always comes after the MAIL FROM command. @Andrew: You say "I have confirmed there is no issues with spf" what SPF is that? From my experience the SPF record refered to in the "Too many messages" error is the SPF record of the domain in the MAIL FROM command and nothing else. So the SPF for mimecast.com wouldn't matter if you send from @yourcustomer.tld We've tried contacting btinternet (@postmaster and support) on several occasions as this is a reoccurring issue with them, but the only answer we've been able to get is that the sender address should have SPF. -- BR/Mvh.
