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
