Create SSL for mail.[domain] [SOLVED]

[curiousclumsy]

Hi,

My server runs on server1.[main domain].com

I have a [second domain].com and an mail.[second domain].com in Cloudflare.

However, I want to issue a lets encrypt to mail.[second domain].com in Keyhelp to allow users to use mail.[second domain].com

Is that possible?

Unless I make use of server1.[main domain].com for email clients, I get this warning:


Thanks

Hallo,

create mail.domain as normal domain in Keyhelp and activate Let's Encrypt for it.
