Our email is hosted by Google Apps. Do you have documentation on setting this up?
The settings should be via the SMTP server settings. Google's SMTP server requires authentication, so here's how to set it up: https://www.digitalocean.com/community/tutorials/how-to-use-google-s-smtp-server SMTP server (i.e., outgoing mail): smtp.gmail.com
SMTP username: Your full Gmail or Google Apps email address (e.g. email@example.com or firstname.lastname@example.org)
SMTP password: Your Gmail or Google Apps email password
SMTP port: 465
SMTP TLS/SSL required: yes
In order to store a copy of outgoing emails in your Gmail or Google Apps Sent folder, log into your Gmail or Google Apps email Settings and:
Click on the Forwarding/IMAP tab and scroll down to the IMAP Access section: IMAP must be enabled in order for emails to be properly copied to your sent folder.
if you are have existing domain/gmail like we do @dsync.com, I would just put that email address in with my password and the above settings for the SMTP
