Hi all. 8/21/2024 and I’m successfully using a secure (smtps) variation of Vladislav’s solution above. To reiterate, you need to enable 2FA on the Google account in order to create an app password for the RocketChat mailer, which you’ll use as the password, below:
Protocol: smtps
Host: smtp.gmail.com
Port: 465
IgnoreTLS: off (forced off by choice of smtps protocol)
Pool: off
Username: Username@GoogleWorkspaceDomain.com (your google email address)
Password: **** **** **** **** (Google App password)
From Email: (same as Username)
