Hi Mnemonic,
I have just seen your message and think this is something I can help you remedy.
I work for a company called Cryoserver who make an email archiving solution which does exactly what you want your program to do. We can help rectify your storage problems as well as making your email repository easy to navigate through and simple to search. We have the ability to de-duplicate emails thus saving on storage, as well as creating email stubs to elevate your mail server storage burden. Also, we can move save your current repository and allow that to be easily searched.
If you wish for me to pass on more details please either PM me on here or email me on jclayton@cryoserver.com and I will show you what we can do.
Many thanks,
James
