Of course you can see that on the SENDING end ... Not on the receiving end though ... -----Original Message----- From: Nico Golde [mailto:nion () gmx net] Sent: donderdag 26 februari 2004 14:36 To: full-disclosure () lists netsys com Subject: Re: [Full-disclosure] a question about e-mails Hallo Chris, * Chris Smith <chris.rs () xtra co nz> [2004-02-26 13:50]:
I have a question for it experts. I want to learn if there is any way of understanding/finding the e-mail addresses at BCC part on an e-mail that
is
send to you. Thanks for your consideration.Um, AFAIK the headers are stripped by the MTA on delivery to recipients (except perhaps the recipient who was listed in the BCC field, but I'm not
sure and will most likely vary between MTA). I'm sure the SMTP RFC would probably help out on this.
I tested it on my system. i send a mail to nico and bcc root. here is the mail header: From nion () gmx net Thu Feb 26 14:28:30 2004 Return-Path: nion () gmx net Received: by via sendmail from stdin id <m1AwLZ0-001n35C () ngolde de> (Debian Smail3.2.0.114) Thu, 26 Feb 2004 14:28:30 +0100 (CET) Date: Thu, 26 Feb 2004 14:28:30 +0100 From: Nico Golde <nion () gmx net> To: nico Bcc: root ^^^^^^^^^ here is the bcc line Subject: test Message-ID: <20040226132830.GA829 () ngolde de> [...] regards nico -- Nico Golde nico <at> ngolde <dot> de public key available on: http://www.ngolde.de/gpg.html echo "[q]sa[ln0=aln256%Pln256/snlbx]sb729901041524823122snlbxq"|dc =========================================================== De informatie opgenomen in dit bericht kan vertrouwelijk zijn en is alleen bestemd voor de geadresseerde.
