-Yarn and Bcc (Blind Carbon Copy) -

With Yarn 0.91 for DOS.
After finding this neat feature with Yarn, I thought it
would be best to pass it on to the List ... and if
someone can explain why it happens - that would be grand.

We want to send a Bcc (Blind Carbon Copy) to a List of
people.

Advantage of Bcc: No one else knows who also receives
the email. We will send mail to the Originator because
the TO: line must have an address. Thus we end up
with the TO: and FROM: line as the same person (the
sender) [We will use me in the examples dw@dw.on.ca]

Example 1: Basic Bcc.

C:\YARN\YARN\ADDRBOOK
David_Wilson: dw@dw.on.ca
The_Team: joe@abc.ca,\
matt@ibm.com,\
bev@company.org

Sender
To: dw@dw.on.ca
From: dw@dw.on.ca
Bcc: The_Team

Receiver
To: dw@dw.on.ca
From: dw@dw.on.ca
Bcc: -

The above example #1 is normal Bcc. The List receives
the Email with no idea as to who else got it. The only
odd item with Example #1 is the Sender sent it to
themselves. Now Look at example #2 ....

Example 2: A twist. Edit the Address Book file with
an ASCII text editor and add at line 2 the following.

dw@dw.on.ca (David_Wilson)

Note that this entry is backwards!
We now have ....

C:\YARN\YARN\ADDRBOOK
David_Wilson: dw@dw.on.ca
dw@dw.on.ca (David_Wilson)
The_Team: joe@abc.ca,\
matt@ibm.com,\
bev@company.org

Sender
To: dw@dw.on.ca
From: dw@dw.on.ca
Bcc: The_Team

Receiver
To: -
From: dw@dw.on.ca
Bcc: -

Thus with example #2 the TO: line is now Blank! and the
Bcc is still Blank like it should be. A nice feature
of the Yarn Address Book.

Questions:
1) Are other getting this result?

2) What is the reason?

3) Where can one find the rules for the Yarn Address Book?
C:\YARN\YARN\ADDRBOOK

4) What site defines RFC 822 ?

I trust this helps others on the list ...
Cheers!
