How to fix this issue in WordPress (Developer) 6.1.1

mail goes properly if I manually check

[nebulon]

On Cloudron one should use the SMTP settings which the app is preconfigured with, or also if other WordPress plugins are used, you can find the SMTP credentials in the app's shell environment. For this open the webterminal and run env.

So basically sendmail is not installed and also the php mail() is not configured and thus not working.

BTW, once configured to use Cloudron mail, you can track the activity in the mail server event log - https://docs.cloudron.io/email/#event-log
