Hi all,
First I would like to Thank you all, it is such a responsive and wonderful community here.
I started to debug the issue by streaming logs and figured that EHLO was being sent when I click "Re-Test" button on thunderbird, another issue I encountered I was not able to connect ports 465/993, It was not blocked by firewall cause I could see live streaming logs, I think it's more on postfix side which I have sent for help.
here are my logs
You issue has nothing to do with dovecot.
From the log it is to be seen that Postfix rejects the attempt on sumissions port 465 because from client side not SMTP AUTH info is being sent. Because you properly configured "smtpd_recipient_restrictions=permit_sasl_authenticated,reject" within Postfix's master.cf
and config ( postfix, dovecot) https://pastebin.com/M3XG9DXA
In case someone could help, I can pay a small amount for figuring out this issue.
Thanks again
Alexander
