On one of my domains I have two email accounts. And now the one guy wants to be able to track what the other guy is doing. So I have used the ISP Config forwarding option where it sends a copy to another address. But now I cant figure out how I can make all the emails that guy sends to also be forwarded. Thanks in advance!
I think you have to try MTA functions, for example Postfix do have such things. For example: sender_bcc_maps = hash:/etc/postfix/bcc_maps recipient_bcc_maps = hash:/etc/postfix/bcc_maps -- GreetZ .:JbRaVo:.
