Every EMail will have a Message-ID, but the rules for generating the 
Message-ID (must be globally unique) tends to mean that its construction 
will reveal a bit about the source (very likely a domain connected to 
the sender). It might just indicate that they send via gmail, and that 
doesn't tell you much, but with some mail systems it might actually leak 
out the email of the poster. (Yes, you could say just don't use those, 
but it is helpful to build the system to keep anonymity without people 
understanding this level of details).

To totally anonymize a message, you want to replace the Message-ID with 
one generated by the list, thus every message will have the same sort of 
Message-ID, removing its ability to trace back (somewhat) to the poster.
