Tracking blind-copied e-mail
Is there a way for me to know if somebody is being blind copied (BCC:) on an e-mail I receive?
There are two perspectives on this question, namely that of the
recipient and the administrator's perspective. If you are the recipient
--in other words if someone has sent you a message and included someone
else on the Bcc: line prior to sending-- then there's really nothing
about the message that will reveal that it was blind copied. So if you're an
end user with no administrative permissions to your environment, there's
really nothing you can do.
If, however, you're an administrator of an
organization and have been asked to perform a forensic-type audit to
determine if someone received a Bcc: of a specific message, then assuming
you have message tracking enabled in your environment, you may be able
to track the message (either track "by message ID" if you know the
message ID or "by sender" assuming you know the sender). Tracking the
message may reveal that it was sent to two parties in which case you've
found out who was blind copied on the message.
