what might be causing this? Further debugging I can do?
Thanks

Is it possible to exempt one sender from receiving non-delivery
notifications? We have a DMARC policy that forces DKIM headers on all mail
and when Postfix sends a non-delivery notification to this bulk mail sender
(a fake e-mail alias) it fails because of our DMARC policy.
I have set notify_class
setting.
After making several tweaks from suggestions in this thread I saw much
better performance last night.

Hello,
We use a Postfix installation on Debian 9 in our network to serve as a
send-only SMTP server for a very large application in our school district.
This application does not have its own built-in SMTP server and requires a
relay to send notification e-mails to students, teachers, and parents
