How to send local mail via postfix to another server

Question

I have postfix set up for use as an STMP server to send mail for my domain, but I receive email for the domain via gmail/google apps. The reason I use my own postfix is because I send out a lot of transactional emails to my customers using a web app, and the volume would exceed what google allows with its SMTP servers.

Everything works fine, except cron & system mail gets routed to local users on the server, not to the appropriate accounts at google mail. How can I route this system mail to the respective google mail accounts instead?

In this case the answer was very simple: blanking out the mydestination entry in /etc/postfix/main.cf

So that server thinks it's not the destination for anything? – Nic Cottrell Mar 04 '14 at 08:58

@NicCottrell - yes, that's my understanding, and it works so far in all my initial tests with postfix 3.3.0 on Ubuntu 18.04. – Johnny Utahh Oct 16 '19 at 23:11

Have you tried using the virutal aliases to redirect the email correctly? I am not sure if this will do what you want to do or not.

Note sure, but I believe virtual aliases require me to enter each username and the corresponding email address individually.. I'd prefer a simpler, widespread solution if possible. – scotts Feb 18 '10 at 23:07
