Unless I'm very wrong here mail clients (including KMail) do not use the
message-id to determine if it should download a message from a pop server or
not since this is part of the message. Instead they use the UIDL function to
retrieve a list of message ids that are on the server. This number is specific
to each server and hence the local cache will be invalid when the server
changes.

For your specific case to work the change needed would make all users who use
pop and "leave mail on server" functionality download the headers and the first
10 lines of each message on the server on every mail check.

With this in mind I'm closing this as wontfix.
