Ive just done a clean install to Buster/ISPConfig3.1.14p2 using the pefect server method (https://www.howtoforge.com/perfect-server-debian-10-buster-apache-bind-dovecot-ispconfig-3-1/) Theres a few things im not certain about. On my previous older 3.1 install there were cronjobs for letsencrypt to auto renew certs and i had the option of adding hooks to restart services. On this install ive enabled LE and its successfully created certificates for the sites needed and they work fine. Ive got a few issues though:- (i) But i cant see what mechanism it uses to test and renew these certs? Am i missing cronjobs or does some other script handle this somewhere now? (ii) in the letsencrypt log i see: WARNING:certbot.cli:You are running with an old copy of letsencrypt-auto that does not receive updates, and is less reliable t han more recent versions. The letsencrypt client has also been renamed to Certbot. We recommend upgrading to the latest certbot-auto script, or using native OS packages. This confuses me as i installed a fresh server using LE from source as in the guide above on the command line. How do i go about fixing this? (iii) i assume i need to manually add hooks to restart apache, dovecot, postfix on cert renew. Previously i had these in a cron job. How do i go about doing it now as i cant seem to find any jobs running to hook them onto?
