I'd like to switch MULTIVERSE to require registration approval, at least temporarily during periods of lower staff availability, but I don't think anyone on our instance is receiving emails at the moment, and notifying users that their application has been approved is something I want to get working before requiring applications. I haven't received My verification email.

Is there a way I can send a dummy email to a specific user? And, do I need to do any steps to get emails working? I didn't configure any email server, is that required?

I there is a /email route for testing email. It's been a while since I read the install doc, but there was a way to test it mentioned in there when I set up my instance.

From the install doc:

Test email sending by going to https://yourdomain/test_email. (after setting the FLASK_DEBUG environment variable to 1). It will try to send an email to the current user's email address. If it does not work check the log file at logs/pyfedi.log for clues.

In the extra info section 😁

Thank you! I was able to send test emails, but didn't receive them, and there's nothing in the logs about the emails

They're probably being blocked by anti spam filters. Ensure you have SPF and DKIM set up on the domain.

Thanks!
