    Hi all,
    I tried installing a third party security certificate using the guide at

    I am now experiencing issues with my email. I can connect to the mailbox via IMAP using TLS (port 143), but when I try and send email I get the following error (from Outlook) when using TLS:
    * On port 465 - "The connection to the server was interrupted"
    * On port 25 - "Establishing an encrypted connection to your outgoing (SMTP) server failed"

    I'm at a bit of a loss as to how to resolve this as my postfix conf appears okay:


    Any and all help much appreciated.

    what does server log say?
    Also, I use LetsEncrypt certs for dovecot and postfix and wrote a little script to auto-renew those certs.
