My apologies for adding to the confusion. I see now that
Yesod.Auth.Email handles database interactions, generates
verify URLs for new accounts to use, and provides forms to
embed in HTML. It doesn't actually create email messages or
handle any kind of email delivery.

I saw the mime-mail dependency, and then forgot
where I had seen Network.Mail.Mime.renderSendMail actually
being called.

My understanding is that none of the plugins included in
yesod-auth are magic in any way. New ones can be created
outside of the official package as long as their associated
AuthPlugin has a Text value unique among any others being
used. Is this all correct?
