I am running Outlook 2010 connected to an Exchange 2003 server. Often times, the spam that I received is sent to "undisclosed-recipients". I'm guessing that's because my email address (or an email address for a group I am part of) is in the BCC field.
Is there a way to find out what BCC address was used to reach me? I looked at the Internet Headers for the message, but am not seeing "Envelope-to", described in a similar question.
