Is it possible through logs, property fields, or debugging to determine the original target (from the receiving server's point of view) of an incoming mail from the internet?
For example, a mass email comes in from some big vendor's SMTP server. They send it to a domino group's internet address (which has several aliases), as a BCC. The receiving domino SMTP server receives the email and the router delivers it to the proper mailboxes. How can the administrator of the receiving domino server determine which alias of that domino group was used by the sending SMTP server with the receiving server?
