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.

There is no such thing as a "BCC field"; BCC in email is performed by adding the recipient to the envelope but not the headers, which means that they are undetectable unless the email server is explicitly configured to reveal them somehow.
