Are you able to see the incoming message in the Postal UI? That should confirm whether or not Postal was able to identify a match for what it was a reply to

[jzapater]

Yes, in Postal is the correct in_reply_to and references.
The problem is that these fields (which are the same) are not passed to the HTTP Endpoint.

if Postal knows which email the incoming message refers to, it should link to it in the UI. If you can't see that link then Postal doesn't know for whatever reason.
