Step 2 . Download the certificate from Let's Encrypt Certificate.
To download certificate execute following command

Step 3. Install the Certificate.
Copy the privkey.pem to the directory as written in command.
[root@mail ~]# cp /etc/letsencrypt/live/mail.linuxworldwithgk.in/privkey.pem /opt/zimbra/ssl/zimbra/commercial/commercial.key
[root@mail ~]# chown zimbra:zimbra /opt/zimbra/ssl/zimbra/commercial/commercial.key
Next, you need to edit chain.pem file and append root CA to it. To get the IdenTrust root Certificate execute following command.
[root@mail ~]# wget -O /tmp/ISRG-X1.pem letsencrypt.org/certs/isrgrootx1.pem.txt

Step 4. Verify your certificate.
Now create a directory /opt/zimbra/ssl/letsencrypt and copy all the certificate files.
[root@mail ~]:~# mkdir /opt/zimbra/ssl/letsencrypt
[root@mail ~]# cp /etc/letsencrypt/live/mail.yourdomain.com/* /opt/zimbra/ssl/letsencrypt/
Next change the ownership of files.
[root@mail ~]# chown zimbra:zimbra /opt/zimbra/ssl/letsencrypt/*
[root@mail ~]# ls -la /opt/zimbra/ssl/letsencrypt/
After that switch to zimbra user and change working directory.
[root@mail ~]# su zimbra
[zimbra@mail root]$ cd /opt/zimbra/ssl/letsencrypt/
Step 5. Now, it’s time to verify and deploy the certificate.
[zimbra@mail letsencrypt]$ /opt/zimbra/bin/zmcertmgr verifycrt comm
[zimbra@mail letsencrypt]$ /opt/zimbra/bin/zmcertmgr deploycrt comm cert.pem chain.pem
At last, just restart the Zimbra services to reload newly installed cerificate
