True, but besides the point. The problem is users are conditioned to think that personal addresses don't exist beyond the big e-mail providers. "Not GMail or Yahoo? You, sir, are a liar, such e-mail address can not possibly exist!" (that is an exaggerated version of what I get with firstname@lastname.com: "so, firstname.lastname@gmail.com?" "no, firstname, at, lastname, dot, com." "so, firstname, dot, lastname, dot, com, at, gmail, dot, com?" ...)
