Problem Install Sentora 2.0.1

[franmm25]

In the end, different results were received regarding the ports, because different providers were not providing clean images for the installation and in some cases they even had php pre-installed, what I do note is that those ports remain closed on 443 and 587. , 443 is released when using SSL and 587 I don't know if Sentora has any procedure to obtain the certificate, if so let's see if you can tell me how to obtain the certificate for postfix and dovecot, greetings and thank you for your help and happy that Sentora continues to evolve, I have been working on the Zpanel project for many years and I use it in all types of projects, thank you very much
