We have problem with SMTPS configuration on Palo alto Firewall
so we have the SMTPS Certificate and already inject to the firewall
Our users says that the certificate is the certificate CA and when we test the email connection, the firewall shows error 'SSL Connect Error', we try on port 465 and using TLS 1.2
We have another brand network device, and the tac support on that brand said their device require the parameter 'extended key usage server authentication' in the certificate to setup the SMTPS.
Are in the palo alto firewall need this too in the certificate so we can config the SMTPS?
or is there any docs about how to troubleshoot the certificate like this?
