Abstract

When mail is sent to a recipient who is listed in the BCC field, he will not receive the reply when and if the other recipients listed in that mail (any other person listed in the TO and CC field) reply back to the original sender. The definition of Blind carbon copy is sending a message to multiple recipients in such a way that what they receive does not contain the complete list of recipients. It is common practice to use the BCC: field when addressing a very long list of recipients, or a list of recipients that should not (necessarily) know each other, e.g. in mailing lists. However, if the sender wants to add a person to BCC in such a way that this person recieves any responses to the mail sent it is not possible. This is a limitation since the BCC list is not saved anywhere and in such scenarios users end up forwarding all the responses to the people who were in the BCC list.

Method and System for permanent blind carbon copy for mails

How mail routes in a Domino system

These steps describe how mail routes in a Domino mail system.

1. Using a mail client, a user creates and addresses a mail message to a recipient.

2. The user sends the message.

3. The user's mail client does one of the following:

- Uses Notes protocols to deposit the message into the MAIL.BOX database on the user's Domino mail server.

- Uses SMTP to send the message to the user's Domino mail server, which must be running the SMTP listener task. The SMTP listener task deposits the message into MAIL.BOX (Lotus Notes, IMAP clients, POP3 clients).

- Uses HTTP to send the message to the user's Domino mail server, which must be running the HTTP task. The HTTP task deposits the message into MAIL.BOX (Web clients).

4. The Router finds the message in MAIL.BOX and determines where to send the message for

each recipient. The Router checks its routing table to calculate the next "hop" for the message on the path to its recipients and determines the appropriate protocol -- either SMTP or Notes routing -- to transfer the message.

- Using SMTP routing, the Router connects to the destination server -- the recipient's mail server, a relay host, a smart host, or one of the servers in the recipient's Internet domain -- and transfers the message.

- Using Notes routing, the Router moves the message to the MAIL.BOX database on the server that is the next hop in the path to the recipient's mail server. The Router on that server transfers the message to the next hop, until the message is deposited in the MAIL.BOX database on the recipient's home server.

5. The Router on the recipient's server finds the message (in MAIL.BOX on a Domino server) and delivers it to the recipient's mail file.

6. Using a mail client, the user retrieves the message from the mail file. Depending on the type of mail client, one of the following protocols is used:

Notes remote procedure calls,

In the diagram above, we are describing the working of Permanent BCC(PBCC), when the sender adds a user in the PBCC field (This field can be added in the e-mail client) the mail uses normal SMTP,

Notes protocols to route the mail to the Mail.box of the sender. Router finds the

message in MAIL.BOX and determines where to send the message for each recipient. The Router checks its routing table to calculate the next "hop" for the message on the path to its

IMAP, POP3, or HTTP.
