curl https://get.acme.sh | sh
yum install socat
cd .acme.sh/

For Zimbra 8.6 and below ( Only in case of zimbra proxy is not running )

./acme.sh --issue --alpn -d mail21c.pahwa.com --pre-hook "su - zimbra -c 'zmmailboxdctl stop'" --post-hook "su -  zimbra -c 'zmmailboxdctl start'"

for 8.7 and Above ( also in case of 8.6 where zimbra proxy is running )

./acme.sh --issue --alpn -d mail21c.pahwa.com --pre-hook "su - zimbra -c 'zmproxyctl stop'" --post-hook "su -  zimbra -c 'zmproxyctl start'"

In case it does not work and give error "Error, can not get domain token entry mail21c.pahwa.com for tls-alpn-01"

./acme.sh --issue --standalone -d mail21c.pahwa.com --server letsencrypt --pre-hook "su - zimbra -c 'zmmailboxdctl stop'" --post-hook "su -  zimbra -c 'zmmailboxdctl start'"

In Case of Renewal , use --renew in place of --issue . You can use --renew --force also .

cd mail21c.pahwa.com/
cp mail21c.pahwa.com.cer mail21c.pahwa.com.key fullchain.cer /tmp
cd /tmp/
