alerting – how to stop a service who crashed to spam all terminals

when a category of failures called “fatal” happen the service spam all terminals with the failure message every second. This is very annoying and disturbed the work on the server.

in the past this was only for kernel critical things, but today even postfix alerts “fatal” because a spam mail does not reach the victim ..

fatal: file /etc/postfix/main.cf: parameter myhostname: bad parameter value: <your hostname here>

Is there a way to stop this?
