I am new to mailcow and a noob with linux but managed to install a fresh mailcow on debian 9 on a vps with my domain email.xxx.com. this morning. and everything “seems” OK.
I have been reading about the SSL certificate and my undertanding is that it is valid for 90 days. I am not sure to understand what I have to do in 90 days when it expires:
1) acme-mailcow client automatically renews it without any intervention
2) acme-mailcow needs intervention: I need to relaunch it with “docker-compose restart acme-mailcow” and it will see the certificate has expired and will renew it
3) acme-mailcow can create it but can ’t renew it and I have to force renewal as explained here : https://mailcow.github.io/mailcow-dockerized-docs/firststeps-ssl/#force-renewal
4) Something else
It would be great if you could enlighten me.
