How to set up a Mail Server that uses GMail as the backend, on Ubuntu/Apache with Multiple Domains on Virtual Hosts
I have multiple domains set up on multiple virtual hosts (Ubuntu 14 with Apache).
I want to create a simple email send and receive system that uses GMail accounts as POP3 mailboxes.
I don't need WebMail, or Spam filtering or Virus filtering, etc., because GMail will do that. I don't need IMAP.
Each domain needs a single email address, no more.
What's is a simple recipe to achieve this? (Note that I have virtual hosts, and I would like each domain to get its own email address using that domain).
Step by step instructions will be most helpful!
