Different network gear I have has had many problems trying to get email alerts working. I thought I would document them. All of these systems use a service gmail address I made on free/public gmail to send alerts to me.
Sophos, and LibreNMS gave me no problems; if you have issues with them drop a comment below and I can post my settings.
The trick to getting Ruckus Unleashed, I used “smtp.gmail.com” and port 587. The issue I ran into is the service email I use to send emails had a long password. Ruckus Unleashed v200.8 supports a maximum of 32 character passwords. I would also mention it dumps the password raw into the logs, so make an account you dont care much about.
After digging through logs and getting lots of “There was an error sending the test email to firstname.lastname@example.org. Failed to send email for unknown reasons.”, I found one post that mentioned a fix for the console log of “fail to send email: api.err.SmtpSendFailed”. You need to once again use smtp.gmail.com, and port 587, but since its TLS, you need to counter intuitively UNCHECK “Enable SSL”.
