When the following is true:
- User attempts to create an account
- Instance has "require registration application" enabled
- Instance's email is not working/unavailable
the application seems to get lost, the user never receives an email (even after email functionality is restored), nor can that email/username be used going forward to re-submit the account creation request.
Additionally, since the user never verifies their email, the instance admin never gets a registration application.
It's not currently an issue for me, however, would it be possible to delete these ghost users? If you lookup the profile/username in the database, you can view it via the web UI, but the only options appear to be either blocking the user or banning them. It might be good to be able to completely delete the accounts, no?
If you use a local postfix relay it should queue messages and retry to send on failures.
I feel like that doesn't really resolve the issue at all... it is merely a workaround.
My email is broken since the 0.18 upgrade and its not postfix related that I can tell. The lemmy app/container itself is tossing errors before it ever hits postfix.
