Follow steps below to complete
mkdir /root/certs # place the cert files in there
rename gd_bundlxx.crt (given by GoDaddy when downloading certificate) to commercial_ca.crt.
mv gd_bundlxx.crt commercial_ca.crt
verify the certificate
cd /root/certs /opt/zimbra/bin/zmcertmgr verifycrt comm /opt/zimbra/ssl/zimbra/commercial/commercial.key ./843535.crt ./commercial_ca.crt
deploy the cert
cd /root/certs /opt/zimbra/bin/zmcertmgr deploycrt comm ./843535.crt ./commercial_ca.crt
restart the zimbra services
su - zimbra zmcontrol stop zmcontrol start
