I've kept email since I switched from Hotmail to POP3 in about 1998. The wonderful bit is I wrote a desktop application which scans any number of hard drives and finds all mail in the main 5 formats (Mbox, Kmail files, Outlook <2003, Outlook 2003, Outlook Express, Eudora). Then you can search it with SQL.

I haven't been able to find a customer for it but I love using it.

But the point is "Don't throw away all that old email, put it in a database so you can search over 100,000 messages for just a few results to look at".
