Need bundle to install email certificate on web server

I have an Apache web server, and got a free email cert to use on it in order to support SSL connections to the server.

I have already provided the .pfx file and password to my web host support, but they also need a CA bundle from Comodo.

I cannot find this bundle file, or any information on obtaining one, on the site. Please help. Thanks!

Wrong certificate type:

Server is SSL
Email is S/MIME
