you could use imapsync or rsync

Make sure you know what you're doing so as not to delete files on the production server.

Hi Eric,

Thanks for the update.
I have shutdown standby server and only running production server, now everything is working without change or rsync from standby server. So as of now no changes and transfer certificate from standby server to production server.

If any issue comes then will follow your above steps.


Another help required from you.
One week emails are in standby server, any possible way  to transfer those emails to live production server while running the production server without affect any existing emailboxes.
Need the commands.

Appreciated your help.

    you could either re-run certificate or rsync the most recent
    certificates over to the production server from standby

    Here's how I rsync (assume production server is 192.168.1.2):

    On standby server (if the most recent keys):

    # sshpass -p "`cat /root/rsyncpass`" rsync -zv -are ssh
    /etc/letsencrypt/ [email protected]:/etc/letsencrypt
    <mailto:[email protected]:/etc/letsencrypt>

    On production server

    cp -p /var/qmail/control/servercert.pem
    /var/qmail/control/servercert.pem.bak

    cat /etc/letsencrypt/live/mydomain.com/privkey.pem
    <http://mydomain.com/privkey.pem>
    /etc/letsencrypt/live/mydomain.com/fullchain.pem
    <http://mydomain.com/fullchain.pem> >
    /var/qmail/control/servercert.pem

    restart dovecot

    stop/start qmail

    Hi Eric,

    my standby server is down now, but still the website and
    certificate is not working in ssl,
