        @Mike-Davis I found this: http://giantdorks.org/alain/fix-for-postfix-untrusted-certificate-tls-error/ but yeah. Should be more or less the same

          @Mike-Davis Mine seems easier. Might want to try it before you get into yours. Could be just that simple

            I do have /etc/ssl/certs, but not /var/spool/postfix/etc/ssl/certs/
            In /etc/postfix/main.cf, it has the line:

            smtp_tls_CAfile = /etc/postfix/cacert.pem
            

            I thought this command was supposed to fix that:

            cat /etc/ssl/certs/Thawte_Premium_Server_CA.pem | sudo tee -a /etc/postfix/cacert.pem
            

            under /etc/ssl/certs they are all from 2008. Could that be the problem?

              @Mike-Davis Possibly? We're reaching the end of my knowledge unfortunately.

                Ran:

                update-ca-certificates 
                

                and that updated the dates on all the files under /etc/ssl/certs

                Then:

                cat /etc/ssl/certs/Thawte_Premium_Server_CA.pem | sudo tee -a /etc/postfix/cacert.pem
                sudo /etc/init.d/postfix reload

                  @Mike-Davis Did that end up fixing your issue?

                    I have to have them send a test fax through. Given that it's 2016 it might be a while before we can find someone with a fax service....

                      @Mike-Davis I have a fax.. but you could setup a test fax service with any online provider and see if it receives the fax they send to it.

                        Test failed. Same error as before. I'm going to see if it's because a CNAME was set up for the receiving mail server and the name doesn't match the cert or something.

                          Instead of testing emails with a fax, get the email working itself first. Work on sending emails directly, once that is working, add in the fax piece. That will make this a ton easier to test.
