Unable to send email

[futureshocked]

Hi all,

I'm testing Commento++, but having trouble getting started because outgoing emails are not working.

Other apps in the same Cloudron installation are working fine in terms of outgoing emails, so I think it is a Commento++ issue.

For example, when I try to register a new account in Commento++, the registration email seems to be stuck in the queue, with new send attempts every few minutes.

Please see screenshot of one such email in the queue below: (https://app.screencast.com/V438iDq57fFof)

How can I fix this?

It seems that the problem is that Hetzner (my VPS) is blocking port 25.

It took me a while to understand that problem because email on other applications on the same host (like Discourse) are working properly.
