forward copies of all incoming and outgoing mail to a single mail box

Hoping someone can help,

The security team of one of you clients has requested that we intercept and forward a copy of every incoming email for a domain and every sent email from that domain to a specific mailbox. That said mailbox could be either in the same domain or external.

Can anyone help here

 

if you're using postfix as your MTA check out recipient_bcc and sender_bcc directives
