Well, yes I do have an archiving system but really i'm only interested in keeping my University mail and a few interesting mails from mailing lists that I know i will want to refer back to but I ensure the mail I want to keep is flagged and archived monthly (usually) and so keeps my current mailbox usage free from large amounts of it. I use mutt macros and other external tools to archive mailboxes on disk etc. like i'm sure most people do. I recall someone mentioned they have the best part of 200,000 emails. For me, I can't imagine why I would want to keep a large number like that. I am sure people have perfectly valid reasons for keeping such large amount, it was just out of curiosity.
