Table of Contents

1. Create the file

<cli> /etc/postfix/recipient_bcc </cli>

2. Populate it by using the syntax

existing_address <TAB> <forward_destination_address>

3. Edit "/etc/postfix/main.cf"

and add (I'd suggest at the end) <cli> recipient_bcc_maps = hash:/etc/postfix/recipient_bcc </cli>

4. Edit "/etc/postfix/master.cf"

⇒ line 9 (smtp inet) by adding a new line under it with <cli>

  1. o receive_override_options=no_address_mappings

</cli> # This avoids duplicates when the mail is re-injected. If you don't add it, every BCC is sent twice!

5. Create the .db-File by running

<cli> postmap /etc/postfix/recipient_bcc

</cli>

6. Initialize the new config

<cli> 

postfix reload

</cli> Each time you add a new BCC you have to run steps 5 and 6

7. Addendum

If is not working (version > 1.0.3) skip step 4 and in step 3 use:

<cli> sender_bcc_maps = hash:/etc/postfix/recipient_bcc </cli>
