To make it easier to obtain PCI Compliance, I need to separate our Web Site/ECommerce Site from the email and certain database driven programs. Can I do this by just setting up 2 separate servers each with it's own ISPCONFIG3 or would it be better to do a Master Server with only 1 ISPCONFIG3 containing the web site setup on it and a 2nd server with the email and other services? Will emails leave the web site server and go to the mail server for our own domain? Will it require the web server to have it's own DNS with records pointing to the email server? The Web Site will need the ability to send emails generated from forms like Contact Forms and Order Forms to people in our domain.
