If you are getting .bdr files in the badmail folder, this means the mail could not be sent for some reason. You might see an error like this, if you open up one of the .bdr files:
Unable to deliver this message because the following error was encountered: This message is a delivery status notification that cannot be delivered. Specific error code was 0xC00402C7 |
The most common cause is that you've either omitted the address in the From or To properties, or included an invalid e-mail address (see

You've reinstalled the IIS SMTP service (see
