[SOLVED] Email notifications not working on Ubuntu

[markus101]

I wonder if it’s a TLS vs SSL issue:

E-mail Notifications Broken

These settings work in NzbDrone to send email through Gmail’s SMTP server: Server: smtp.gmail.com Port: 587 SSL: checked Username: Your Gmail address Password: Your Gmail password Send From Address: Your Gmail address Send To Address: Your recipient address The only difference from most guides online is using port 587 instead of 465. The difference appears to be security protocol related: 465: SMTP with SSL/TLS 587: SMTP with STARTTLS

587 works, but 465 doesn’t, but in Sonarr (and .net) it’s referred to as SSL, not TLS.

Are you connecting to a public SMTP server or your own?

@Ashpool

I wonder mono could be at fault.

I wouldn’t rule it out, easiest way test would be testing the connection from Sonarr running on Windows.
