Hi Lucas, I know that your post is old, but I found it several minutes ago. There is one big disadvantage of the mentioned e-mail authentication — the unsecured e-mail transports and unsecured (unencrypted) mail in general. Every mail server administrator can steal your access if it is fast enough. It is definitely not a good solution unless all users will have certificates/PGP and an S/MIME or PGP encryption is regularly used. I will be glad for your response because I can not imagine that you miss looked it.
