Choose a suitable envelope sender address:
$ sendmail -f sender -bv recipient
The result is returned to the sender address. With a suitable
transport mapping to route this address to a pipe + script, you can
parse the DSN which is in RFC-standard form.
Success looks like this:
Final-Recipient: rfc822; u...@example.com
Action: deliverable
Status: 2.1.5
Remote-MTA: dns; ...
Diagnostic-Code: smtp; 250 2.1.5 Ok
All other cases are "undeliverable".
Final-Recipient: rfc822; u...@example.com
Action: undeliverable
Status: 4.4.4
Diagnostic-Code: X-Postfix; connect to host[addr]:25: Operation timed out
In these cases you need the Status field to decide if the error is
permanent or temporary.
