EECG : Email mailing-list Blocking

On 30 January 2006, ECE staff installed a mail filter (milter-regex) on our mail servers to prevent outsiders from sending e-mail to our local mailing-lists. Here are some interesting statistics:
- put into "production" on mail server: 30 January 2006
- first message caught: 30 January 2006
- most caught in one day (since installation): 5927
- most caught in one day (last two weeks): 160
- total caught since installation: 1165309
- total caught today (since this morning at 4:15): 47

Here's a plot of the data for the last 14 days, updated automatically at about 45 minutes past every hour (unless a manual update is done).
