@jimcarroll @molly0xfff That’s right. I worked on supporting others a couple of years ago and even submitted a code change for it. That didn’t fit their standards and was rejected. https://github.com/TryGhost/Ghost/pull/14984
I didn’t pick it back up because Mailgun has a free plan up to 5,000 emails per month, and I use that.
I also use SES at work and Mailgun is a nicer product to use.
