A Tour of Domain Records for Email

There are growing concerns, in the circles that I travel in, about the use of “free” email services like Gmail, that lock you into a service that may not have your whole interest in mind. The remedy for this is to use an email address with a domain that you control.

Those setting up their own mail server fall beyond the scope of this post, although the general aspects will probably be applicable here as well.

So, without further ado, here are the domain records you’ll need for email.
