How can i debug email?

[Stephan-P]

I've made some variations in the SMTP settings, each time restarting VoidAuth. Some of these enable the button 'Send test mail', most of them do not.
When the button Send test mail is enabled, it may send or maybe not. I can't tell, as I do not receive any mails.

So, how do I debug the Sendmail function in VoidAuth, because in not receiving anything?

I think the most that you can debug SMTP would be to set the debugging environment variable ENABLE_DEBUG=true and see if there is anything useful in the error message. VoidAuth uses nodemailer for SMTP internally, so you may be able to trace errors or lookup settings for your mail provider on their documentation.
