Date: 2015oct12 Product: Postfix Q. How can I use a Godaddy certificate with Postfix? A. You get a .zip with MYDOMAIN.crt and gd_bundle.crt from Godaddy. In /etc/pki/godaddy:

cat MYDOMAIN.crt gd_bundle.crt > server.pem cp MYDOMAIN.key applications.pem

In /etc/postfix/main.cf:

smtpd_tls_cert_file = /etc/pki/godaddy/server.pem smtpd_tls_key_file = /etc/pki/godaddy/applications.pem

And restart postfix
