IF(A73X) {TRUE;}

Step 1: Install certbot-auto tool

wget https://dl.eff.org/certbot-auto
chmod +x certbot-auto

Move the script to directory in your PATH.

sudo mv certbot-auto /usr/local/bin

Confirm it working.

sudo certbot-auto --version

Step 2: Stop Zimbra Proxy Service

We need to stop the jetty or nginx service services before we can configure it to use Let’s Encrypt SSL certificate.

$ sudo su - zimbra -c "zmproxyctl stop"
Stopping proxy...done.
$ sudo su - zimbra -c "zmmailboxdctl stop"
Stopping mailboxd...done.

Step 3: Obtain Let’s Encrypt SSL Certificate
Once the Zimbra proxy and mailboxd services are stopped we can proceed to request for Let’s Encrypt in auto mode. Make sure you pass all the hostnames used by your Mail Server.

# export EMAIL="[email protected]"
# certbot-auto certonly --standalone 
  -d mail.computingforgeeks.com 
  --preferred-challenges http 
  --agree-tos 
  -n 
  -m $EMAIL 
  --keep-until-expiring

You can find all your files under /etc/letsencrypt/live/$domain

$ ls -lh /etc/letsencrypt/live/mail.computingforgeeks.com
