I note that my server is different from https://doxfer.webmin.com/Webmin/Let%27s_Encrypt
let say my server host.fqdn was server1.adam.com
hostnames for cerfticate on my system = server1.adam.com
Website root directory for validation file = other directory "adam/public_html"
Also, I dont understand Months between automatic renewal. Is the first option "only renew manually" or is that the second option?
In what way will my changing my system to match the tutorial affect existing domains and email on my system?
Also, When i Run SSL tests on email accounts on my server for various domains, they are all showing the same (incorrect expired) certificate for Usermin. The certificate shown is for a billing.adam.com (that no longer is even on this server). I dont actually know how it ended up like this, anyway...it needs to be changed.
what is the safest method of fixing the above problems for webmin and Usermin SSL without adversely affecting other domains on the system?
