[SOLVED] If I setup External DNS do I still have to route through MIAB?

Like another poster, I am using sendy.co via amazon ses for my newsletter. I am setting up an External DNS version of MIAB so I can still use Sendy. Will this still cause sendy messages to be flagged as spam if it has dkim and all that jazz set up too?

If you set up SPF and DMARC properly (or not at all), then it should be fine. But I can’t help with that.
