Hi I added a auto_bcc in my postfix config, and now I don't know how to remove it.

This is what I did:

Per user bcc for Zimbra

in /opt/zimbra/postfix/conf, create a file called sender_bcc and added the user you wanted to copy/send to:

in /opt/zimbra/postfix/conf/main.conf, add:

sender_bcc_maps = hash:/opt/zimbra/postfix/conf/sender_bcc

then run as zimbra user

postmap /opt/zimbra/postfix/conf/sender_bcc

And restart all the stuff:

postfix reload
postfix stop
postfix start

How do I remove that? it seems like it created a database entry or something like that.

If you just want to disable the functionality, remove or comment out the line you added to

The postmap command you ran generated a .db file, which lets Postfix do more efficient lookups than if it were to parse the text file every time. Both the sender_bcc and sender_bcc.db files are safe to remove after you remove the sender_bcc_maps line from and reload or restart Postfix.
