That command is missing -starttls imap? or are you using port 993?

Excellent, thank you again.
The openssl command I have tried (that used to work with Dovecot 2.2)
is:
openssl s_client -connect mail.privustech.com:143
I have also tried
        openssl s_client -connect mail.privustech.com:143 -servername
mail.privustech.com
I've posted the full output from this to  https://pastebin.com/eUSarQdx

I've posted te full output from dovecot -n to  https://pastebin.com/F8Ra

Thank you again, Andy

Hi,

that error above typically means to connect with SSL to STARTTLS or
vice 
versa.

Please provide the complete command you issue using "openssl
s_client" 
together with the corresponding dovecot logging. As well the output
of 
"doveconf -n" would be useful to help you further.
