No need to 'force' Exim. Just nibble the ears gently... - You can add (or remove) headers in the 'aleter' acl's or in router/transport sets. You cannot add headers during initial 'connect', 'helo/ehlo'. 'mail-from', or 'recpt-to' phases because there is not yet a message in the hands of the MTA to hang them on - only a negotiation as to whether a message can be conveyed. In some cases, added headers behave as if they were flags or buffers being carried along for final 'recording' at a later stage, so have a care when taking action on a header that it is/is not actually locked-in yet. Give some thought to using custom X-headers to do whatever you need - then removing them as the last stage of off-box transfer. That keeps messages cleaner, neater, a line or several shorter, reduces risk of conflict with header titles used by others, makes any special steps you are taking less visible.
