    Hi Christoffer,


    I tried to get more information regarding your question and for this, "Outbound" policy route need to be updated (empty by default): add the IP addreses of the SMTP sender host into policy route (System > Policy Routes).


    Once you have defined the policy route, edit the rule and use "Restrict processing to selected policy routes" and/or to "Disable processing for selected policy routes" option to include or exclude the rule for specific users or groups.



    Restrict processing to selected policy routes: outbound

    Disable processing for selected policy routes: default_inbound

  • Hi.
