Setting up the Google Apps for Business Outbound Email Gateway
If you’re a Google Apps for Business Email customer, setting up the email service to direct outbound email to Brand and Sign is literally a 1 minute job.
In the My Accounts section of the Brand and Sign app, copy the SMTP Server name (usuallysmtp.brandandsign.com) and then login into your Google Apps Management Dashboard for your domain.
Your’re done, and now all your outbound email will route through Brand and Sign’s servers.
To stop routing email through Brand and Sign’s servers, simply clear the server name from the Outbound Gateway and save changes again.
