Lets's encrypt SSL certificate, issues with mail clients.?

Hi All,
Just wondering if the LE SSL certificate for the server name is/was a good decision as I have imported cPanel accounts and nearly everyone get the message that the SSL certificate is not trusted.[SIZE=10px]https://showbox.bio/ https://tutuapp.uno/ https://vidmate.cool/[/SIZE] It doesn’t matter if it are Apple devices or Windows based clients. Anyone experience with this or advice?

Hi EdgarIsmael

welcome to IW forums

This has been covered before a few times, and for the moment,the best advice is to use the FQDN of the server for MX for clients, which LE would have created the SSL on

eg FQDN server domain, myserver.url mail server uses mail.myserver.url to clients connect to mail.myserver.url

There will be no issues on encryption as the SSL Cert is correct

This applies even though on siteworx accounts LE can set SSL cert for their MX record (if pointed at your server)

The mail is changing from qmail which AFAIK, the new mail software should include SNI for mail clients, but it is on the roadmap

Many thanks

John
