title: How to suppress email validation when using SmtpClient and MailMessage
body: <p>When sending out emails using the SmtpClient and a MailMessage (.net 3.5) the "To" email address(es) get validated prior to sending. I've got a big stack of email addresses which have a dot (.) before the at-sign, causing a FormatException when you attempt to send the message using the SmtpClient. This is actually a good thing, because by specification a dot before the at-sign is invalid. Unfortunately, those emails exist in the real world and they get delivered, if you send them out using your preferred email client. </p>
  
  <p>My question is, can email validation through the SmtpClient/MailMessage be suppressed?</p>
