I modified my anti-spam system to send those notifications, containing
an URL allowing the sender to unlock his message if it was mistakenly
intercepted. That would have been appreciated.
However, I had to see that:
- most of the end-users don't read mail they don't expect. They
won't take the time to read a lengthy explanation about anti-spam.
- you will send e-mail to un-existant addresses, as you said.
- worse: you will send e-mail to existant addresses, but who haven't
really send the spam. You will definitely get complaints from them.
- worse yet: if by misfit you happen to send a notification to a
spam-trap address (ie a spammer collected e-mail addresses from WWW
space, then used some to send spam out so to defeat filtering, such
as mailing-list filtering), you will be (your server!) listed in
ORDB, RBL or similar databases. This happened to me.
