Postfix: SASL local relay vi Gmail relay (with @domain forwarding)
I'm setting up a new droplet, Ubuntu 14.04 LAMP stack. I'm looking to x-fer over my primary domain, but ran into a snag when looking at email forwarding -- essentially, now I'm having to do this myself...
In my searches, I found a great configuration which I really like, but I'm worry on reliability (i.e. Google going no-no): I've setup Postifx @domain.com foward to my @gmail account, using smtp.gmail.com STMP relay host. The idea is postfix would accept the message, and then immediately relay it through to Gmail.
Local email, using sendmail / mail, does work. But, I hadn't tested remote yet (given the dependency of my @domain email working).
My question is: is this option viable? Is there any possibility Gmail could cut off my relay? (using my login on the relay) While I have a basic understanding of SMTP, I don't fully understand how mail relays through mail servers.
