The gitea user settings have a “hide email address” tickbox. Then it suggests using username@noreply.gitea-instance.tld as the email address for commits.

What happens when someone uses the address? It seems a gitea admin could have an mail server on noreply.gitea-instance.tld, which could do anything the admin wants, such as:

• forward the mail to the users secret address (though the “noreply” string would be deceptive in this case)
• refuse all msgs on connect
• accept msgs then auto-reply with a msg
• accept then blackhole msgs
• have no mail server at all

Is that the case? There is no universal expectation of what happens with email in that case?

This bug report shows the initial discussion.. though it does not answer my question.
