Hello, It doesn't look like you can do this in sogo. However, you probably can configure your smtp server to remove this header. Example with postfix:
global: main.cf: header_checks=regexp:/etc/postfix/header_cleanup header_cleanup: /^X-Forward;/ IGNORE could be restricted to submission if added this header_checks in corresponding service (master.cf) Quentin -----Original Message----- From: users-requ...@sogo.nu <users-requ...@sogo.nu> On Behalf Of Frank Richter Sent: jeudi 7 mars 2024 12:51 To: users@sogo.nu Subject: [SOGo] How to disable X-Forward header? Hi, when sending e-mails SOGo writes the IP address of the user in the e-mail header: X-Forward: IP We have to disable it for privacy reasons. Is there a possibility within SOGo?
