I am using the user creation wizard in asp.net 2.0 and using it to send the
user an email message when their account is created, well this works great
if the address is a valid mailbox, but when it is not it throws an exception
(shown below) how do i prevent this?
Description:

For most users, this new feature is actually very convenient. If you want to control the update process,...
