tldr:
I want to be able to stick a filter / milter AFTER smtp(8) so I can
save the remote server response code and associate it with an email
that was sent so my PHP application can display the status of a
notification sent to a user.
Looking for docs on how to do this.
Long story / background / additional info:
I have an automated bug tracker that sends email notifications to
users when something they are working on needs their attention.
Sometimes, people complain they don't get the messages. So, I end up
going through mail.log to see what the problem is, and invariably, I
see the email was sent to their address with a "250 OK Queued as..."
response, which means it's not my problem.
So, here's the question:
I would like to add a python script that would be able to read /
store the remote server responses for a given message. I will stuff
an X-Header into the mail before I send it so that the Python script
can associate the exact email with the exact notification that goes
out.
The point here, is that if a message with X-Header XYZ 1234 was
sent, and we received a 250 OK back from the remote server, we know
we've done everything we can to deliver the message. It's now
outside our network.
if, on the other hand, I get something like a 551 5.7.1, we know
that something is wrong and we've been classified as spam. Or, as I
recently saw with one of our users: 550 5.1.1 user unknown because
the user in question is unable to type their own email address
properly... .twice. (The form requires you confirm it, so they
really had to try to fail).
*If I can insert the python script as a filter (or milter?) AFTER
smtp(8), that would be perfect. I could read the X-header injected
by the PHP application to get the message ID as the PHP application
knows it by, and then read the response code to find out the
disposition of the message.*

Where in the docs can I find information on doing this?
