Hi, I see the following post.
How To Relay Postfix mails via smtp.gmail.com on Ubuntu 14.04.1 https://community.runabove.com/kb/en/instances/how-to-relay-postfix-mails-via-smtp.gmail.com-on-ubuntu-14.04.html But the problem is that all users on the same ubuntu server will be able to use the same google account to send emails. Is there a way to configure postfix so that each Ubuntu user will use his/her own google account to send emails? Thanks. -- Regards, Peng
