Are there any publicly available personal mailboxes except for the Enron corpus?
Doesn't have to be a large corpus, even a single mailbox of a single person will help me (step by step...)
Technically it would be best to have it in mbox format, but I would accept any format.
I am interested in both work and personal mailboxes, in any language. Having said that, I am not interested in mailing lists and forum threads (which are also widely available in the same format - mbox).
To be more specific, I'm looking for mailboxes that are large (50+ outgoing mails, 1000+ will be even better) and not just a single thread of communication with the same person or a handful of mails.
