Hi all, I am currently having a weird issue with my osticket installation.
OS: Ubuntu 20.04.4 LTS
Apache2
Php 7.4 

I am ingesting emails via pipe (with postfix). Inbound emails are working, tickets are being created and "New ticket alert" are being sent. What is not working are "New Message Alert" for the messages sent by email, if the user adds a comment via web, the assigned agent gets the email notification, but if the user replies via email the update gets to the ticket but no alert is sent to the agent.
 
Is there any difference in the configuration for New message alerts between web updates and email (pipe) updates? I also reviewed email configuration deeply, the php mail function and the smtp options works. No error in the logs either.
 
Alerts and notices settings:
