We have enabled an auto reply message for one of our recipient address. Issue is if the sender has similar configuration, the emails are looped. How do we exclude such emails based on header? Say, if the email as X-AutoResponse-Suppress under header, there shoulnd't any response sent by our IronPort

You autoreply function should check if the following headers are present in the emails:
Auto-Submitted
Precedence
X-Auto-Response-Suppress
and of course NOT to generate autoresponse when these are in original message.
Then your autoreply message should have following headers set:
insert-header("Auto-Submitted", "auto-generated")
insert-header("Precedence", "bulk")
insert-header("X-Auto-Response-Suppress", "All")
The problem is that not every "autoresponder" application honors those headers. So, some of the autoresponders are using null envelope sender email address - like non-delivery-reports - to avoid loops.
