    Thank you in advance for your assistance.

    I have a simple problem that I am having trouble fixing.
    I have a web app that sends mail through a postfix server as, however the actual Postifix server is
    When the app sends the email that appears to come from to the real it is seen as spoofing and is rejected.
    Whitelisting is on is not an option so my thought was I could use Header_Checks to replace * with [email protected].

    I have tried several examples seen around the internet but none are working:

    /From: *$/ REPLACE From: [email protected]

    Would this be a viable solution? This server is used ONLY to send email to and for internal alerting on server health (which I control those servers).

    Any help or suggestions are greatly appreciated.
