Exim configuration for no-reply

Hello, I've added the following router in the Exim configuration (WHM - Exim Configuration Manager - Advanced Editor): Section: ROUTERSTART

# Router to disable no-reply addresses reception
noreply:
  driver = redirect
  local_parts = no-reply
  allow_fail
  data = :fail: Sending only address

This should disable e-mail reception of 'no-reply' accounts for all domains hosted on the server, meaning all messages received by no-reply@anyhosteddomain.com account should be discarded with an error message. This no-reply accounts then could be used for sending only. no-reply local part accounts hosted externally should not be affected, so we should be able to receive e-mails from them. But now a client is claiming 'lost messages' sent from a no-reply@... external account (3rd party hosted) and when I search the logs I find this:

2021-06-14 16:43:11 H=(UYITAEXCH01.xxx.com) [x.x.x.130]:9172 X=TLS1.2:ECDHE-RSA-AES256-SHA384:256 CV=no F= rejected RCPT : Sender verify failed

2021-06-14 16:47:34 H=(UYITAEXCH01.xxx.com) [x.x.x.130]:9529 sender verify fail for : Sending only address

Is there something wrong with my Exim config snippet? Thank you in advance

Hey there! I've been looking at this for a bit now and doing some research, and I'm not seeing anything obviously wrong on my end. If you have a second server, you could create an account and then create an email address called "no-reply" to see if you can reproduce the issue on demand. This level of customization to Exim isn't something I'm intimately familiar with, so I can't say for sure how that is supposed to behave when it's working, since we don't do much tweaking on our end with that here at cPanel.

Hey cPRex, I did the test you suggested with a second server and I could determine... This router config is crap! I really appreciate your help!!

Ha! There might be a way to go about doing that, but you might be better served by reaching out to the Exim users list directly for more advanced configurations with that software.
