You could inherit from the SimpleMembershipProvider and just override the ValidateUser method like this.

public class ExtendedSimpleMembershipProvider : SimpleMembershipProvider
{
    public override bool ValidateUser(string login, string password)
    {
        // check to see if the login passed is an email address
        if (IsValidEmail(login))
        {
            string actualUsername = base.GetUserNameByEmail(login);
            return base.ValidateUser(actualUsername, password);
        }
        else
        {
            return base.ValidateUser(login, password);
        }

    }

    bool IsValidEmail(string strIn)
    {
        // Return true if strIn is in valid e-mail format.
        return Regex.IsMatch(strIn, @"^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$");
    }

}

This is just one approach. You could write your own MembershipProvider but if you only need to change the ValidateUser method this should work.

Add the following configuration to the web.config to setup the provider.

That should get you going in the right direction.
