What Server Am I Using

I don't know which server I am using for newsletters sent from my site. I receive emails to service@primequalityproducts.com which is the web mail and forwarded to my comcast account. When I send the newsletter I don't know if it goes directly to a web mail server or thru Comcast server. How can I find this info.



Not an expert but would say is being sent from where your site is (server).

As a side note visited your site and at bottom (footer) there is a smarty error which I will PM to you.
