What is it for?
It is used to reliably sending emails from your server to your customers and it only works for outgoing email.
Why do I need it?
Public IPs in cloud servers change hands lots of time and can be in blacklist in some cases (depending on the usage someone did before). This means the email you send from your server to your customers can end up in the Spam folder. Using Gmail as a relay for your outgoing email will ensure that this doesn’t happen as emails are delivered from the Gmail SMTP on behalf of your server.
Who needs this add-on?
Anyone sending emails to their users or customers from his or her servers.
