You are confusing terminology. Yes, ASSP sends a "message" back to the sending server, but its not an email. Its an SMTP Reply code (3 digit number) with a verbose description following it. The sending server will then send a boilerplate email message to the sending user based on the reply code it received when attempting to send the email. The boilerplate email to the sending user is called a DSN - Delivery Status Notification. The receiving server should not be sending the *email* message. That should be done by the local sending server. Anything else is easily abused as backscatter. ASSP handles all of this correctly and does not contribute to backscatter. http://www.asspsmtp.org/wiki/SMTP_Status_Codes#Example_DSN ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
