I think there is no easy and convenient way to prevent address spoofing.
So one have to take the risk to copy a "wrong" mail.

Perhaps you can modify your system filter so that it parses the mail
header for mail addresses in mail_backup_users. If an address appears in
a "From:"-Line the you have an outgoing mail, if it appears in a "To:"-
or "Cc:"-Line the it in an incoming mail.
