I'm a newbie trying to wing it after our Sys Admin left. I needed to update our wildcard certificate and copy it onto our mail server.
I renewed the cert at Namecheap, downloaded it, and installed it on our webservers. Everything is showing up fine in a browser for websites. However, when navigating to the browser portal of our mail server, it is still showing the old cert. I have restarted Postfix, but nothing has changed.
In my /etc/postfix/main.cf:
# TLS parameters
smtpd_tls_cert_file = /etc/ssl/certs/wc2_mydomain.com.combined.crt
smtpd_tls_key_file = /etc/ssl/private/wc2_mydomain.com.key
smtpd_use_tls=yes
However, in the browser, it still shows the old expiration date even after postfix reload
(it should be 2022):

What am I missing? It's going to be very bad if this doesn't show up correctly come Saturday at 6:00pm.
