I've added a wish list item to our project tracker for a way to resend the confirmation.

I do not think it is a good idea to disable the requirement that emails are verified. If the user is a site member and is already validated then it is not needed and will not be sent, but in any other case if we are allowing anonymous users to subscribe then they should be verified otherwise bots may come along and subscribe a bunch of email addresses that do not belong to them and once you get a few people reporting you for spam it is very difficult to undo the damage and the sender email and ip address will get added to all kinds of spammer black lists and then your messages will land in the spam box for most people. Protecting the reputation of your email sending account is very important in order to have success with a newsletter. So I don't think I should build it in a way that invites you to do it wrong. For those who want to do it anyway you can update it in the database to verified in the mp_LetterSubscribe table.

Best,

Joe
