Email Notification "Communication error"

Hi,

I just set up traccar on digital ocean 2 days ago, and I am trying to set up email notification on my traccar server, but I keep getting the error "communication failure".

I have tried entering the details in the configuration file and as user attribute, smtp for yandex mail, zoho mail and outlook. Still no luck.

I have tried SMTP for yandex mail on the demo server, and it works just fine.

This is what i see in the log

Anyone can point me in the right directions?

There is nothing related to SMTP in your log. Communication error usually means that server hasn't replied.

Ok. After further searching online, I realise that digital ocean blocks SMTP ports for new users.
