MArch

MArch (march-20130520.src.tbz), pronounced as the month, is a daemon program that saves email going through a mail server into a database. It plugs in the Sendmail mail delivery system as a milter. Messages can then be recovered, searched, read, forwarded via an HTML interface. flowers in a forest

Some of its features:

Here are some snapshots of the web interface (new versions of MArch may look slightly different):
[search screenshot] The search results page.
[search screenshot w/legenda] The hot-spots show:
  1. Query entries with constraints on sender, recipient, subject, month, and category. The list order can be by date, subject, or sender. By default the search page shows today's messages, but you can choose another day, month or week.
  2. Menu bar that appears on every page. This includes some shortcuts to get to the list of all messages of this month/week/day and the one before.
  3. A navigation bar to move back and forth days/weeks/months.
Below is the list of messages satisfying the query.

  1. Smile icon, when message is in the ham category (not spam).
  2. Devil icon, when message is in the spam category.
  3. Balloon icon, when message is neither in the spam nor in the ham category. That is, the Bayesian filter was unsure about the quality of the message contents.
  4. Outgoing icon, when message has been leaving the domain.
  5. Incoming icon, when message has been entering the domain.
  6. Number of messages satisfying the search query.

  1. Navigation bar to quickly jump to the most used pages.
  2. Some summary data, including information from the message headers (sender, subject, receiver, date), the internal MArch ID, the list of categories it belongs to and the spam score (normally not shown).
The rest is the message body.

  1. Thumb down button to change the rank of the message to spam.
  2. Magnifying lens button to get to the raw message (including headers).
  3. Input box to forward the message to someone.
  4. Current position in the discussion thread.
In the blue box you see the discussion thread.
[unsure sample screenshot] A non-spam message which the Bayesian filter hasn't been able to asses with certainty.

[general statistics screenshot] Statistics page about some general facts of the database and the type of traffic sen by MArch since it was started.
[hourly statistics screenshot] Today's statistics of the database contents, divided per hour. Included is a line chart of the frequencies per hour and a pie chart of the overall contents divided per ham (green), spam (red), unsure (grey).
[daily statistics screenshot] Statistics for the current month, divided per day. Included is a line chart of the frequencies per day and a pie chart of the overall contents divided per ham (green), spam (red), unsure (gray).
[spam statistics screenshot] Two tables showing the top keywords (features) currently stored in the Bayesian table. The one on the left is the list of keywords with the highest spam rank. The one on the right is the list of most frequent keywords. On the top you see some figures regarding the overall spam table and the cache used by MArch to speed up their access.

To compile MArch you need SCLF, CLOT, demyltify, MIME4CL, HTML-sugar, and CLiconv, all from this page, plus a handful of other external packages/libraries. See the README for further details.

MArch has been developed and tested on FreeBSD running CMUCL. It should be rather portable, though.
