I think DMARC is missing email address with IPv[46] literals support. As being self-hosted, without paying the DNS mob, I am still blocked to send email to gmail.com because such email addresses do throw out of whack gogol code.
Email addresses with IPv[46] literals are intrinsincly stronger than SPF. If in the envelope or any of the 'from' headers (if my memory does not fail me, there are few more headers to scan), the IPv[46] literal does not match the actual and real IP of the SMTP server, the email is dropped, not even going into any spam folder.
Conspiracy mode: they know and are careful not to support that, in order to create a walled garden of internet messaging for them and their friends.
- inigyou 2mo agoWasn't this removed from the email standards?
- lxgr 2mo agoArguably, missing IP literal domain support is pretty far down the list of things creating today's actual mail delivery walled garden.
- kube-system 2mo agoIt is not a conspiracy theory that it is hard to maintain reliable delivery with self-hosting email. It is primarily because email filters are in part based on trust relationships, and huge amounts of spam come (or at least, did) from relatively unknown originating servers.
- sylware 2mo agoSpam does not work with email addresses using IP literals.
- kube-system 2mo agoBecause, as I just said, it's unlikely to be deliverable.
- sylware 2mo agoSpam relies on trust the user gives to the domain name in the email address of the from header, you dumb dumb.
- PunchyHamster 2mo agoMost people don't own their IP range so it's moot point to support it.
- drdexebtjl 2mo agoI think DMARC is missing support for homing pigeon characteristics such as the markings and colors on its crest and plumage. As being self-hosted, without paying the IANA and ISP mob, I am still blocked to send email to gmail.com.
- sylware 2mo agoRegulation on small tech interop is exactly for guys like you.
- inigyou 2mo agoI thought it was a joke, that Gmail should be mandated to support receiving by carrier pigeon.
- drdexebtjl 2mo agoYou could even say the joke flew right over their head :) —- Sent from my pigeon
