AFAIK the Bcc: address list is never found in the MIME headers at it is a
list of _blind_ addresses - i.e. addresses that do _not_ show up in the
messages, but whom the
mail is delvered to as well. They do show up in the SMTP envelope, as RCPT
TO: addresses during SMTP conversation.
This is an example of how such a conversation could look like:
S: 220 mail.mydomain.com; ESMTP Tue, Mar 25 2003, 00:49:12
C: HELO bluebear.mydomain.com
S: 250 mail.mydomain.com Hello bluebear.mydomain.com Pleased to meet you
C: MAIL FROM: [EMAIL PROTECTED]
S: 250 2.1.0 [EMAIL PROTECTED] Sender ok
C: RCPT TO: [EMAIL PROTECTED]
S: 250 2.1.5 [EMAIL PROTECTED] Recipient ok
C: RCPT TO: [EMAIL PROTECTED]
S: 250 2.1.5 [EMAIL PROTECTED] Recipient ok
C: DATA
S: 354 Enter mail, end with "." on a line by itself
C: From: [EMAIL PROTECTED]
C: To: [EMAIL PROTECTED]
C: Subject: Test message
C:
C: Dear Saundra, this is only a test, please disregard.
C: .
S: 250 2.0.0 h2ONqQm26855 Message accepted for delivery
C: QUIT
S: 221 2.0.0 mail.mydomain.com closing connection
You see the main recipient is listed in the MIME header ("To:"), but the
Bcc recipient ([EMAIL PROTECTED]) is not; it only shows up during the SMTP
conversation (the "envelope" part).
AFAIK it's a feature of the mail client; be it an email program or a mailer
class.
