Hi

we are using dovecot on secure port

when i try to command

openssl s_client -connect mail.mydomain:pop3s 



it works perfect. 

it says ***OK Dovecot ready***

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
