Login to server as root
$ letsencrypt renew
Change directory to Zimbra Letsecnrpyt SSL folder
# cd /opt/zimbra/ssl/letsencrypt/
Copy new SSL files to Zimbra Letsencrypt folder then change owner to Zimbra.
# cp /etc/letsencrypt/live/yourdomain.com/* . # chown zimbra:zimbra /opt/zimbra/ssl/letsencrypt/*
Add X3 root certificate to our chain.pem as described in here https://letsencrypt.org/certs/trustid-x3-root.pem.txt at the bottom of chain.pem

Now let’s check our certificates are verified via Zimbra certificate manager
# su zimbra $ /opt/zimbra/bin/zmcertmgr verifycrt comm privkey.pem cert.pem chain.pem
If you see done message in your console, first make a backup of course…
# cp -a /opt/zimbra/ssl/zimbra /opt/zimbra/ssl/zimbra.$(date "+%Y%m%d")
Before deploying the SSL Certificate, you need to move the privkey.pem under the Zimbra SSL commercial path, like this:
# cp /opt/zimbra/ssl/letsencrypt/privkey.pem /opt/zimbra/ssl/zimbra/commercial/commercial.key
We are ready to deploy new certificates, run deploycrt command via zmcertmgr.
# su zimbra $ /opt/zimbra/bin/zmcertmgr deploycrt comm cert.pem chain.pem
At last, restart.
# su zimbra $ zmcontrol restart
