New SSL Cert now showing up for Postfix in browser (Ubuntu, Namecheap)

Solution 1:

I figured it out. I was on the right track. My /etc/ssl/certs/wc2_mydomain.com.combined.crt file was simply out of order. I discovered the correct order in this article (at the bottom)

It states:

and the correct way is this:

SSLCertificateFile /etc/apache2/ssl/certificate.crt
SSLCertificateKeyFile /etc/apache2/ssl/private.key
SSLCACertificateFile /etc/apache2/ssl/intermediate.crt

I simply had my certs out of order! :D My browser interface works, and the cert shows expiring 2022. Thanks for the nudges in the right direction friends. Another crisis averted.
