This module periodically checks your certificate to see if it is about to expire soon. The time before expiry is printed in the logs. About a week before a certificate expires, reminder messages will be sent to admins.


Simply add the module to the modules_enabled list. You can optionally configure how long before expiry to start sending messages to admins.

modules_enabled = {
checkcerts_notify = 7 -- ( in days )
