Re: How can I view the Bcc line in a received message?

I wish to view the Bcc line in some received messages; perhaps also other
hidden information. How can I do this?

Unless the sender's e-mail client is broken or modified, and unless your
receiving mail server doesn't deliberately strip it out if it exists, there
is no BCC header for you to see. The To, Cc, and Bcc headers are *DATA*
within the sender's copy of their message are are *NOT* used to designate
the recipients of their message. The sender's e-mail client compiles an
aggregate list of recipients from the To, Cc, and Bcc headers and presents
that list of recipients in the RCPT-TO commands that it issues to the SMTP
server. You never get to see the list of recipients specified by the
RCPT-TO header issued by the sending e-mail client because that was a
command to the SMTP server, not part of the message. The fact is, the To,
CC, and Bcc headers are optional (and only a screwed up e-mail client would
include the Bcc header): they may appear zero or one times in the headers -
and the headers are just the first part of the *DATA* of the sender's
message, not the commands used to route the message.

In short, you don't get to spy on what other recipients were included by the
sender. The sender didn't want you to know, perhaps to prevent recipients
from spamming the other recipients. There may be cause and justification
for the communication between the sender and a recipient but not for
communication between the recipients.
