I don't see this. envelope-from is not a message header. It is the
argument of the SMTP MAIL FROM: command. Some MDAs will expose it as
Return-Path:. It is allowed to be empty if you don't want DSNs returned
to the sender.
In any case, what I see in MailScanner is notices to email senders have
a null envelope sender, but notices to the Mailscanner admin have an
envelope sender with the admin address. However, both kinds of notices
have a To: header with the recipient's address and a From: header like
From: MailScanner <admin at example.com>
where admin at example.com is the value of the `Local Postmaster` setting.
Have you set that?
