case test

2004-05-26 05:44:29
Hi,

I've read some threads in this ml and browsed the web to understand how some 
projects and company think to stop the SPAM problem.

I'd like to know something about a special case I had in my mind.


Alice uses her mail client to write a message to Cindy and wants Bob to 
receive the same message without telling Cindy.

From: alice(_at_)alice(_dot_)dom
To: cindy(_at_)cindy(_dot_)dom
BCC: bob(_at_)bob(_dot_)dom

However Bob is using a forwarding account, so mails sent to 
bob(_at_)bob(_dot_)dom will 
be forwarded to bob(_at_)forwarded(_dot_)dom

So we'll have 4 SMTP sessions:

(1)....... Alice's mail client -> Alice's outgoing mail server ...............

Mail From: alice(_at_)alice(_dot_)dom
RCPT TO: cindy(_at_)cindy(_dot_)dom
RCPT TO: bob(_at_)bob(_dot_)dom


(2a)......... Alice's outgoing mail server  ->  Cindy's MX ..................

Mail From: alice(_at_)alice(_dot_)dom
RCPT TO: cindy(_at_)cindy(_dot_)dom


(2b)......... Alice's outgoing mail server  ->  Bob's MX .....................

Mail From: alice(_at_)alice(_dot_)dom
RCPT TO: bob(_at_)bob(_dot_)dom


(3)......... Bob's MX  -> Bob's forwarded.dom MX .....................

Mail From: alice(_at_)alice(_dot_)dom
RCPT TO: bob(_at_)forwarded(_dot_)dom


I've 2 questions:

1) Is this BCC forwarding supported by any of proposed methods ?

2) If so, how is it handled ? Reading headers ?


Thanks.


        Ed
