Fix a secured mailserver

[Copernicus365]

Hi
I have successfully installed some things so that my Debian 10 is a mailserver. I have followed this guide: https://www.tecmint.com/install-postfix ... in-debian/
Everything works.

Now I wonder if it is possible to make the e-mails encrypted (I think it is port 993) with this Debian setup?
