I use Google apps for business.
I am essentially trying to find a way to redirect all my emails from Google apps to go through an external SMTP server.
There is a small catch though.
My SMTP server requires authentication. (Similar to a service like Sendgrid etc.).
The inbound email would still come in untouched.
Please see the attached image to understand the scenario better.
I didn't find a setting to specify the username and password for outbound smtp server in google apps.
If you can help me figure out a way to accomplish that, that'll be awesome.
