Project: SpamKilla
Technologies: Cold Fusion, SQL
URL: (Not publically available)
Features:
- Kills 100% of spam
- Makes having an email account an enjoyable thing

Notes:
A whitelisting tool I built which checks my email accounts every few minutes, and compares the sender's email to a "safe list" which I specify. If the sender is not on the list, the email is deleted, stored aside in a database, and then an email is sent back to the sender with instructions on how to automatically add themselves to my safe list. This method eliminates 100% of my spam because spammers won't take the time to follow the directions to be added. Admin area allows me to add or remove individual emails, add entire domains to the safe list, and recover any emails killed within the past 48 hours. Anything older than that is automatically purged nightly.
