Unfortunately I am ignorant about all those things you ask in your four points.
Does using SNDSMTPEMM provide for those things?

Almost certainly not.

DKIM, DomainKeys, & DMARC require configuration on the mail server and
DNS (to publish public keys).

One other thing I forgot to mention was publishing SPF DNS records.

Here's a pretty good explainer for those concepts:

RDNS can be set up with your ISP, assuming you have a static IP.

I had to jump through hoops with Amazon to get RDNS setup for the
midrange.com list server.

In a nutshell: Sending email, and getting the mail delivered, used to
be very straight forward ... but isn't anymore.
