[SOLVED] Copy inbound mail from one domain

[KatyComputer]

I want all messages from the gmx.com domain to be copied to copygmx@localdomain.com, it seems like this should work, but does not:

In /etc/pmg/templates/main.cf.in :
sender_bcc_maps = hash:/etc/postfix/bcc_maps

In /etc/postfix/bcc_maps
*@gmx.com copygmx@localdomain.com

Any idea what I am doing wrong? Is there a better way?

Why not set filter rules to bcc the email?
