Trying to wrap my head around how bulk email providers (Salesforce, etc) would operate in this? I guess you could give them a subdomain of your main domain and have a separate MX2 record. This might help silo off newsletter, transactional, and actual person to person messages like many already do in the current environment.
- gjsman-1000 2y agoIt's a little confusing, but my idea is that there would be multiple MX2 records for every authorized sender's key. One of those MX2 records would have a marker on it for incoming mail.
- thecosas 2y agoAh, gotcha. Feel like I've got the existing MX stuck in my mental model. Honestly with all of the existing DNS record based "authentication" with SPF, DKIM, DMARC its already a mess for bulk senders too lol. Thanks for putting these thoughts together :-)
