Good day, since update from 4.2.0 (now on 4.2.2) we're unable to receive notifications from Jira, neither agents or customers. The notifications inspectors show that notifications are working well, but on email queue sent emails from Jira are stuck in with errors.
We didn't make any change in the email sending account and is working well. How can we make this feature work again? This feature is very important for us.
