I don't need to create a full blown email implementation.I don't need to receive emails from anybody.I just want to be able to to send emails from no-reply@mydomain.com for password resets, email address verifications, things like that.And I would like to at least make an attempt to have the emails I send pass through a basic spam filter. So I assume at the very least I need to setup DKIM and SPF records.Is it as simple as following  and  ?(That is the route I am taking right now, will report back here what I find out in a few hours!)
