Yes. You are absolutely correct regarding SMTP. However I suspect many people will switch to Letsencrypt for everything (web and mail).
I for one set up a self signed email certificate with a 10 year lifetime because this is work. That isn't really a good plan. Letsencrypt, once it works, seems like the way to go.
