The headers you get to see in a received email are only part of the
story. When an email is submitted to a mail server for delivery the mail
server is also being told separately whom to deliver it to and from
where the message originated. This must not necessary be the same
address that appears in the headers you get to see. This information is
handled separately in what is commonly referred to as 'the envelope'.

Yet, some more sophisticated mail servers are so helpful to put this
additional information in the actual lines that you get to see. This
facilitates tracking down the intended recipient and the originator
(which in the case of spam is faked most of the time anyway). The mail
server over which your sample spam originated was not one of the
sophisticated kind. :(

Sending mail via BCC uses the envelope to tell a mail server who the
mail should go to. The actual address will not show up in the mail
headers. (Unless it is a badly configured mail server.)

I hope this clarifies the matter.

Regards,

Markus
