Getting programatic feedback from an smtp server

Hi,
I have an application which sends emails.
Currently we use the mailenable web server.
If an email is not sent successfully then we want to update the email
address in our database as unreacheable automatically.
In other words we want a mail server that when it gives up sending an
email will do an http post, or will somehow communicate with our
software so that we can update our database.

Does anyone know if ther is a mailserver which will do this?

Many Thanks
Simon

I'm not familiar with 'mailenable' however this functionality is built in to
SMTP. If a SMTP server is unable to deliver a message it uses the address
provided in the MAIL FROM command to send a delivery status notification
message.

Failures ought to be arriving at the mail box specified in the from address.
If you don't want failure reports being delivered to the you applications
from address you can add a Return-Path header to the message to contain a
mailbox address which you can then monitor programattically and update your
database.
