Issues with Let's Encrypt certificates

Hi,

Everything works on my new server which is running for almost 2 months now. Getting a license is good and works too.

But.

When clients connect/configure their account in their mailsoftware, they get waings about the certs which is 'invalid' since it's from my server hostname and not from ex. mail.theirdomain.com

When connecting with Filezilla, so I connect to ftp.clientwebsite.be - ssl is also showing invalid since i see my srv.jerrixhosting.be (hostname where DA runs ons/server hostname).

How is this possible and furthermore, how to fix this?

Hello Jeroen,

You should enable MAIL SNI per this guide: https://www.directadmin.com/features.php?id=2019

As for FTP there is no solution yet, you can use SFTP instead or your hostname.
