There is no way I will let some third-party online tool access my inbox. Privacy and security are much more important to me than some fancy gimmick visualisation.

I would love to do this kind of analysis on my mails. Any chance for a local offline tool?

I wrote software which scans a hard disk for email in any of 6 formats, converts them to Mbox (eg, standard, with emails one after another in plaintext), creates 2 indexes (full-text and SQL) then lets you search all your emails with a Lucene query (full text of email bodies) or an SQL query (MySql or PostGres or SQLite - SQL database of common email headers). It doesn't run on 'the cloud'; it's a Windows application.

An example search is 'All emails from "geocities.com" between March 2009 and April 2009, with attachments.

I haven't found anyone who wants such a program. Anyone here interested?

For Linux users there is "notmuch" for full-text searching. http://notmuchmail.org

Uses the excellent Xapian library to perform just about any search you'd need.

Why mbox instead of, say, Maildir? The irreversible mangling mbox requires makes me reluctant to use it as an archive format.

It can output single emails to folders named after months (eg, 2011_10_18), which I think is MailDir.

I'm interested too... Jeremy@Zawodny.com (since I've considered writing such a beast myself like a dozen times)

Absolutely. It fits my usage nicely.

If you're interested, we could talk over email.

Do you have an email address or do you want me to post my email address? Or not? ;-)

I updated my profile to show it, I think.

Something like this was featured on HN a while ago: http://sluggish.homelinux.net/wiki/Emailgraph

The article says the tool runs locally.

If you click on "Other accounts" at the top then you can point it at an mbox folder, if that's what you mean by "local offline".

MUSE is a Java applet that runs locally.
