      Using http://www.checktls.com/ it seems to show the cert is validated and OK and was able to use TLS 1.2 successfully for the connection.

      Master.cf

      smtp      inet  n      -      n      -      -      smtpd -v

      submission inet n      -      n      -      -      smtpd -v
        -o smtpd_tls_security_level=encrypt
      #  -o smtpd_tls_security_level=may
      #  -o smtpd_sasl_auth_enable=yes
      #  -o smtpd_client_restrictions=permit_sasl_authenticated,reject
      #  -o milter_macro_daemon_name=ORIGINATING
      smtps    inet  n      -      n      -      -      smtpd -v
        -o smtpd_tls_wrappermode=yes
      #  -o smtpd_sasl_auth_enable=yes
      #  -o smtpd_client_restrictions=permit_sasl_authenticated,reject
      #  -o milter_macro_daemon_name=ORIGINATING

      Using 25 or 465 with no SSL/TLS or STARTTLS option checked works

        It doesn't matter what any thing else thinks of the cert.  pfSense has to trust it.

          Ok, then how will I know as the cert and postfix settings have not changed since my last alert email, i see nothing in the logs showing cert issues with pfsense 192.168.1.1

          pfsense logs show this error over and over

          php-fpm /system_advanced_notifications.php: Could not send the message to gmail.com – Error: could not start TLS connection encryption protocol

            The two places I know of for the CA to be located in pfSense are:

            1. System / Certificate Manager / CAs
            2. /usr/local/share/certs/ca-root-nss.crt

            This is not to say there couldn't be some other location.  These are just the two I'm aware of.
            I am also not sure in which of the locations it is required to be for notifications.  Mine is in both.  But I'm thinking it probably has to be in ca-root-nss.crt.

              Did you have to hand edit ca-root-nss.crt to add the CA?

                Yes, I just added it below all the other CA's and incremented the number of certificates.

                Mine is a self signed, so I have to added it.  I wish PHP curl could use it from the one that is in config (System / Certificate Manager / CAs) so it would survive upgrades and I wouldn't have to remember to add it to the file.

                Here are the results of notification test message with and without and with my CA added to the ca-root-nss.crt file.

                  According to a kdiff comparison it appears this certificate was present in 2.3 but is absent in 2.3.2.  If that is the CA for your cert then that would likely be why it quit working.

                    Great! Thank you all for your help! I will add the CA for the current cert from the mailserver and post if the issue is resolved.

                    @NOYB - another thing I noticed that the standard web interface cert is shown as OK in firefox while chrome throws the caution error, any way to correct this as I have not had any luck getting a cert for just the IP anymore, used to but have not be able to recently. Alt would be to use the domain name, but I find the IP more reliable.

                        I imported my own self-signed cert and the CA for it  (System / Certificate Manager / …).  Then configured Admin Access to use that cert for SSL and installed the CA in my browsers trusted roots.
