postmap the file. test by postmap -q "<mailto:1...@1234test.com>1...@1234test.com<mailto:1...@1234test.com>" /path/to/transport Taken from http://www.postfix.org/transport.5.html look under table search order -- Med venlig hilsen / Best Regards Christian Ejlertsen Lytzen IT A/S Tlf: +45 88328788 Dir: +45 88328707 On Wed, 2020-12-02 at 18:04 +0000, Chu, Uy wrote: Hi, I currently have 2 postfix servers as our gateway servers hosting our domain. It is currently configure to receive internet email bound for our domain and then send it to our ProofPoint servers for hygiene scrubbing. This is all working great right now, but our Cyber team wanted us to implement a journaling mailbox/server and bcc all inbound and outbound to/from the internet emails to this mail...@server.com<mailto:mail...@server.com>. How can I create that route so that when I use the always_bcc = mail...@server.com<mailto:mail...@server.com> that it will not go through my normal route to our ProofPoint servers. Thank you for your help.
