When setting up email initially, how does one send and track the results of sending a test email?

Also, the authorization process is rate-limited to 3 emails per hour, preventing me from using that to send an additional test email that way

Have you already seen this page? maybe useful?

Nice trick for you: to register a new identity try adding +something after your email username. Example: smith+test1@example.com. That is a secret feature of mailboxes.

That sends me to my inbox here -- do you mean, on my own instance?

Indeed :)

Once I get back to working with that instance, I suppose I'll go to my inbox -- where (you seem to be implying) it will show me errors from when the system sent me the initial authentication email? That seems like an odd location, but ok.

Sorry for the confusion. I mean that the /mail/ page is the Mail Dashboard that allows to see both Inbox and Outbox (visible from the left sidebar menu). For example this is the exact Outbox sub-page:

What issues did you run into when using ./bin/mail send-test?
