Hi iRedmail team,

For let's encrypt cert renewal, I see there is a service "service certbot status" and I also see a folder "/etc/letsencrypt/renewal-hooks/post" which is empty after fresh iRedMail-1.7.2 install.

Also I see this line "1 3 * * * certbot certificates; certbot renew --post-hook 'ln -sf /etc/letsencrypt/live/<domain>/privkey.pem /etc/ssl/private/iRedMail.key; /usr/bin/systemctl restart postfix dovecot nginx' " in "https://docs.iredmail.org/letsencrypt.html".

Question:
Instead of setting up a cron job, is it possible to setup a bash script in "/etc/letsencrypt/renewal-hooks/post" as below?

#!/bin/bash
/usr/bin/systemctl restart postfix dovecot nginx

I believe this will work as post-hook to restart "postfix dovecot nginx" after certificate renew.

Anyone tried this and worked or should we still use the CRON as in the "https://docs.iredmail.org/letsencrypt.html"?
