BCC is a header so why you put it in the mail-body?
Because:
"Email header lines are not SMTP commands per se. They are sent in the
DATA stream for a message. Header lines appear on a line by themselves,
and are separated from the body of a message by a blank line."
http://tools.ietf.org/html/rfc5321#appendix-B says the following:
It is recommended that the UA provide its initial ("submission
client") MTA with an envelope separate from the message itself.
However, if the envelope is not supplied, SMTP commands SHOULD be
generated as follows:
1. Each recipient address from a TO, CC, or BCC header field SHOULD
be copied to a RCPT command (generating multiple message copies
if that is required for queuing or delivery). This includes any
addresses listed in a RFC 822 "group". Any BCC header fields
SHOULD then be removed from the header section. Once this
process is completed, the remaining header fields SHOULD be
checked to verify that at least one TO, CC, or BCC header field
remains. If none do, then a BCC header field with no additional
information SHOULD be inserted as specified in [4].
From that I assume the behaviour I expected in my first email is
correct. i.e. Adding email addresses to a "bcc:" header in the DATA
section which postfix then translates into "rcpt to:" commands, whilst
stripping the addresses in bcc.
Although "should" in RFCs mean "recommended".
