Thats broken all right. Please tell us just what broken piece of
software is generating these so we can laugh at them.

which is probably an interesting comment on the UIDL inplementation. I
don't think thats safe.

No.
The only way I can think of is to detect for this case using a
conditional smartuser director, divert to a specialised transport,
which smtps the message to your own mail server again, stripping the
message-id header with a transport filter. Its not exactly what you
would call clean.
