Hello, I’ve had a look on those posts, and i’ve pretty much used the same config that i’ve posted above.

How to send email alerts using Gmail

Sending email alerts Because I know it’s not obvious from the interface and the documentation is vague, I’m writing this tutorial to document the process for configuring the email settings for Graylog and for configuring alerts to be sent via email. I’m using CentOS7 as a base, so instructions will differ if you’re using the OVA or another distribution. Configuration is also for Gmail as that is our email provider, so adapt to your own service where necessary. Configure graylog server Firstly…

Non of them seems to work. The logs aren’t much use either, as I can’t see any email related logs.
Any further advise would be much appreciated
