Local, searchable mail archive

Would anyone be able to recommend an approach or software on either Windows or Linux that would enable me to replicate the MonetDB mail archives to my local machine to make it easer to search for answers and study topics before posting questions asked before. Even if I could get an export of the whole thing in some format that be consumed by a mail client. I did read that mailman is capable of such archives, but it seems to require a real administrative user and password to create the archive. I wouldn't expect a frequent completely up to date copy of the archive, just a backup that is closer to now and stays reasonably up to date (few months) Thanks for any suggestions.
