Hi, on one of my ISPConfig 3.2 Servers, mail clients complain about expired SSL-certificates. The Let's encrypt certificate was renewed today, and it worked out fine for ISPConfig itself but it seems, the mailsererver did not get the new certificate. Any Idea how to fix this?
How does this trigger look? I set up the server, using one of the HowTos here for Debian stretch, back in 2017 and updated it to buster last year...
I believe this article should no longer be used, but this is the way it was set up previously: https://www.howtoforge.com/tutorial...ote-this-shouldnt-exist-together-with-courier ISPConfig 3.2 should know how to restart services when certificate is renewed, I think it uses systemd to detect changes in certificate files. Have you tried ispconfig_update.sh --force and let it reconfigure services? Try to find whether you server uses certbot or acme.sh (the common issues script shows this), then figure out why services do not restart when certificate renews.
@kommid likely uses a manual LE setup due to the age of his setup. I guess it might be the safest way to keep it like that and just configure a restart of required services as described here: https://www.howtoforge.com/securing...server-with-a-valid-lets-encrypt-certificate/
