Error sending email for non-existent user

Hi everyone analyzing the email log file, I noticed that the neth server continues to send notification messages to the asterisk user that no longer exists. I previously removed the freepbx package but evidently there is something left on the configuration level in the system.

Do you have something in /var/spool/cron/asterisk ?

Maybe @thorsten can help you:

related: Asterisk removal and notifications

yes ihave this :

If you no longer make use of freepbx/asterisk it should be safe to remove /var/spool/cron/asterisk directory.

Fully removing freepbx is a bit more daunting, you can read some experiences searching the forum.

So can I erase the asterisk folder that is in the spool?

If you don’t use asterisk, yes.
