I was wondering if anyone thought of applying filters to email post delivery, pre-read.

Basically the idea would be to head off Spam, Malware or Phishing for already delivered email. Malware would probably be the least likely target, as (knock on wood) user workstations would be updated, but a targeted phishing scam would not create a public signature that would be downloaded, yet an admin may have a regex that could be used to remove that email before it left the server.

I used to run find and grep on my Maildirs, but that's no longer practical. I think maybe an 'on connect', or 'on read' might be an option.

Thoughts?
