it works perfect.

Also   i check from

https://www.sslshopper.com/ssl-checker.html web page i can see all correct
ceritificate paths

but i try to this command

openssl s_client -connect mail.mydomain:pop3s -starttls imap

it says CONNECTED and hang. second command is correct?

also my thunderbird client doesnt work with 143 port and STARTTLS. is this
general issue or have we config error?

thanks in advance

You are connecting to pop3 ssl port and attempt STARTTLS. Try

openssl s_client -connect mail.mydomain:imap -starttls imap

Check logs for possible errors.
