reloading postfix after certificate-renew

[pmf]

is there a smart way to reload postfix after the certificates have been renewed? i understand that pve-daily-update.timer starts pve-daily-update.service which runs /usr/bin/pveupdate. but there is no renew-hook-option like in certbot (as far as i can see).

so change pve-daily-update.service and use something like ExecStartPost and reload postfix daily? or are there better ways to do this?

thanks in advance.

This works as long as the unit file isn't updated. Maybe a separate cronjob/systemd-timer with a small script might help.
