Logging of mails that could not be delivered.

[maisen20]

Describe the feature you'd like

An entry should be added to the logs if an e-mail could not be delivered during registration.

Describe the benefits this would bring to existing BookStack users

In my case, I had mistakenly entered an invalid / non-existent e-mail address when registering. The application then showed a message/toastr after registration that the e-mail could not be sent.

After a few adjustments in EmailConfirmationService.php, I was able to see that I had entered an email address that did not even exist for my domain.

It would be good if this were visible in the logs.

Can the goal of this request already be achieved via other means?

No
