We have our JSM set up to not accept cases/emails from users it doesn't know.
This means we get the details and messages in the email logs as expected
Sorry, self-signup is disabled for this help center. You need to be invited first.
This is an oddly worded message as it is worded as response but only ever shows up in a log we can see.
Is there anyway we can actually respond to emails to tell them that the email was not accepted ?
Otherwise this is a manual task to check the logs, download the emails and check what needs to be done.
