I am currently rebuilding an old installation on Debian bullseye. Everything works fine so far, except that no messages are sent by mail.
On the old system where mail notifications are working it looks like this when sendeing a manual notification:
[2022-12-31 16:22:13 +0100] information/ExternalCommandListener: Executing external command:  SEND_CUSTOM_SVC_NOTIFICATION;hostname;service;0;icingauser;Test manual Notification
[2022-12-31 16:22:13 +0100] information/Checkable: Checking for configured notifications for object ‘hostname!service’
[2022-12-31 16:22:13 +0100] information/Notification: Sending ‘Custom’ notification ‘hostname!service!service-notification’ for user ‘icingauser’
[2022-12-31 16:22:13 +0100] information/Notification: Completed sending ‘Custom’ notification ‘hostname!service!service-notification’ for checkable ‘hostname!service’ and user ‘icingauser’.
On the new one I only get this line and no mail is sent out:
[2022-12-31 16:26:03 +0100] information/ExternalCommandListener: Executing external command:  SEND_CUSTOM_SVC_NOTIFICATION;hostname;service;0;icingauser;Test notification
I cannot figure out where the issue comes from.
All the notification, user, host, service, command etc. Configuration in the director are exactly the same as in the old installation.
Does anyone have an idea what the problem could be?
Thanks a lot
