I keep some old emails. I clean up randomly when I have nothing better to do. Other than a few reg emails, most of it is valueless. Keep many more in my business account, "just in case". I have to admit that I use Mail/Entourage (personal/work) as a hack database in that I will often search for a person's name or product name to find associated info (contact data, etc.). So that can lead to keeping more email than I probably should.
