postfix sender_bcc

[maclenin]

Hello!

Given the following configuration within plesk 12.0.18 (centos7):

/etc/postfix/sender_bcc
# contents
a@same.com backup_a@same.com
b@same.com backup_b@same.com
c@same.com backup_c@same.com

/etc/postfix/main.cf
# at the end of the file
sender_bcc_maps = hash:/etc/postfix/sender_bcc

# run after set-up
postmap /etc/postfix/sender_bcc
postfix reload

# confirm creation of
/etc/postfix/sender_bcc.db

Questions:

1. Will emails sent from a@same.com to b@same.com be blind copied to backup_a@same.com?

2. Or will only emails sent from a@same.com to b@different.com be blind copied to backup_a@same.com?

3. I have forwarding set up in plesk using the same logic. Will forwarding in plesk conflict with the sender_bcc configuration? Should I set up both sender_bcc and recipient_bcc in postfix and switch off forwarding in plesk?

3.a. Do the same rules apply to incoming / recipient_bcc and sender_bcc (as in 1. and 2.)?

4. What happens to this configuration when plesk updates?

5. If plesk updates break it, is there a way to make this configuration "permanent"?

Thanks for any guidance!

It works. I will edit the OP (in the body of this post) to clarify:

Plesk version 12.5.30 / CentOS 7

All actions performed as root:

1. nano /etc/postfix/main.cf
# sender_bcc
sender_bcc_maps = hash:/etc/postfix/sender_bcc

2. nano /etc/postfix/sender_bcc
a@same.com backup_a@same.com

3. postmap /etc/postfix/sender_bcc

4. Restart postfix as root <---- or reload (need to clarify - both seem to work)
postfix restart

The only unanswered question (thus far) involves what happens to the sender_bcc configuration in the face of plesk updates or upgrades....

I have kept (recipient) forwarding within plesk "ticked" (and functional).

More, anon!
