Problems with mail address validation

Hi

This is an awesome plugin!

I do have a couple of problems, though. One of them being that email address validation does not work properly, which means that either the user does not get a mail or else the user is prompted to enter a valid email address (even if the address is perfectly valid).

Scenario 1:
Mail is considered invalid if user enters upper case letters in email address

If a user enters an email address (e.g. to have the result of a quiz sent to his/her email), then the user gets an error: “You must specify an email address.”

The error only occurs in case of a capital letter anywhere in an email address (e.g. [email protected] or [email protected] etc.).

Workaround is to ask the user to enter the email in lower case, but I’d rather that it worked in all cases 🙂

Scenario 2:
Mail that ends with a ‘blank space’ is accepted in interface, but no mail is sent to the user.

This scenario probably occurs mostly on mobile phones, where a users email address is auto-completed. Then a ‘blank space’ is added to the end of the email address.

The user is not notified about this. The result is that the user has entered an email address (which is valid, apart from the trailing space) and is expecting a mail in his/her mailbox. But a mail is never sent…

Is it possible to have these issues fixed (soon)? 🙂

Thanks and regards
Johnny
