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
