The 'fast' as in low-resource and highly predictable way is simpler and
requires
less 'logic':
In the remote_smtp (or equivalent) transport, add/include:
headers_remove = Received
CAVEATS:
- Violates spirit if not letter of RFC.
(But not as badly as filtering on the wrong headers!)
- Wise to have an *unaltered* copy archived for troubleshooting. We store two -
one by originator, the other by destination - for quicker findingness.
;-)
HTH,
