I have a domain hosted by A2hosting.com which uses "LetsEncrypt" but I have a subdomain using SME Server 9.

The difficulty was that  accessing the subdomain website would be blocked by Google as a self signed site.

Going to Cloudflare.com and selecting the free option it sets up for the domain and subdomains, it creates a https: connection , paid versions cache things like photos for faster speeds but for the moment my concern was getting a https//subdomain.domain site. that Browsers would not put warnings up of self signed certificates.

Domain and Subdomain issue resolved. Mail issue created.

Issue I do use the subdomain for email paying  for a Static IP,  instead of using A2hosting for email I use SME Server (Koozal) as one can increase the email size in SME Server (Koozal) and as well the large emails are sitting locally instead of at a host 1000 miles away. To set the DNS to get the email to work I did have to watch this Cloudflare Video

Mail entries require 2, one in the form of  A record   mail.subdomain.IPAdress  and must have Cloudflare caching turned off so it states DNS as per the Video  which will put a little triangular warning sign beside it as not cached.
MX entries will automatically have the Cloudflare caching turned off, so it states DNS .
Sub domain MX entries are in the form of  mail.subdomain.domain
If you are using the SME server as a domain - omit the subdomain so its mx record is mail.domain and A record is mail.IPaddress.

Note: As certain email clients limit email sending to from 5 to 20 megs I set up a form on the SME server using Open Source software https://sourceforge.net/projects/soupermail/ , one can thus receive form information and attachment up to the size you allowed on SME server (Koozal) 100 megabytes or even 500 megabytes or more.

Maybe in Koozal 10 I will learn how to set up LetsEncrypt on the Koozal server but for now using Cloudflare works.

Great. In the case one has been successful using Letsencrypt my previous mention is still useful if they care to use Cloudflare to reduce loading on their server and still keep their mail server working.
