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?
