BCC to Boss Function - Postfix
Postfix provides three mechanisms:
always_bcc = address
Deliver a copy of all mail to the specified address.
sender_bcc_maps = type:table
Search the specified "type:table" lookup table with the envelope sender address for an automatic BCC address.
recipient_bcc_maps = type:table
Search the specified "type:table" lookup table with the envelope recipient address for an automatic BCC address.
These features are implemented in postfix 2.1 and later versions.
always_bcc
Add the following entry in /etc/postfix/main.cf to forward all mails in the server to administrator@example.com.
always_bcc = administrator@example.com
sender_bcc_maps and recipient_bcc_maps
You can setup these functions as follows.
[root@postfix ~]# touch /etc/postfix/sender_bcc
[root@postfix ~]# touch /etc/postfix/recipient_bcc
[root@postfix ~]# postmap sender_bcc
[root@postfix ~]# postmap recipient_bcc
Then, open /etc/postfix/main.cf and add the following lines in it.
sender_bcc_maps = hash:/etc/postfix/sender_bcc
recipient_bcc_maps = hash:/etc/postfix/recipient_bcc
verify the following files are generated once the above steps are finished.
/etc/postfix/recipient_bcc.db
/etc/postfix/sender_bcc.db
You can add entries as like follows in sender_bcc and recipient_bcc. This will forward mails from user@domain.com to other@example.com.
[root@postfix ~]# cat /etc/postfix/sender_bcc
user@domain.com other@example.com
[root@postfix ~]# cat /etc/postfix/recipient_bcc
user@domain.com other@example.com
Finally reload postfix,
[root@postfix ~]# postfix reload
