Table of Contents
1. Create the file
/etc/postfix/recipient_bcc
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)
recipient_bcc_maps = hash:/etc/postfix/recipient_bcc
4. Edit "/etc/postfix/master.cf"
⇒ line 9 (smtp inet) by adding a new line under it with
-o receive_override_options=no_address_mappings
# 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
postmap /etc/postfix/recipient_bcc
6. Initialize the new config
postfix reload
Each time you add a new BCC you have to run steps 5 and 6
