Hi there, I don't think offlineimap will be of much help here. It never
really looks at the content of mails or headers. (with one exception)
I think your best bet would be a small python script that walks through
your mails, slurps them in with the "email" module, sets the header
correspondingly and saves the mail again.

good luck
