Actually, that's not entirely accurate. The Yesod scaffolding tool generates a site that uses mime-mail and sendmail, but there's nothing inherent in yesod-auth requiring either. 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.
The stock email plugin does not let you disable these features, but it should be easy to write your own.
You could just copy the email module from yesod-auth and make the modifications there. Or even better if you're so inclined: submit a patch to make these features optional. If you are so inclined, feel free to contact me for some guidance.
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?
Yes, that's completely accurate. Michael
