Make a secret copy of sent email in Postfix

I have a business need. I need to send automatically generated email from a specific business address to my customers. Postfix does not help you to save it to “Sent” mailbox. Although I have mail logs telling me that emails have been sent to the correct email addresses but I really don’t know what is being sent.

Because I setup my own mail server, this is going to be really easy. There is no need to change my business code to BCC a secret address, which is not very nice.

The steps are simple.

Add the line to /etc/postfix/main.cf

sender_bcc_maps = hash:/etc/postfix/sender_bcc

Write your sender_bcc file

[email protected]  [email protected]

Generate the hash.

cd /etc/postfix
postmap sender_bcc

This will generate a .db file.

Reload postfix

postfix reload

Then all your email sent from [email protected] will automatically bcc’d to [email protected].

  1. Is it also possible to make exceptions so that the email would only be forwarded if the recipient of an email is not a specific email address?
