What about the following SPAM illimitating email procedure idea:
Have a user and/or central (MTA) automated mail reply service which does
- incoming email from unknown senders (stored in a database) is replied with
a unique number in it. Or if the email sender address is in the
it is forwarded to the recipient. If not the sender has to reply (push
reply button/send) on
this email with the unique number (in e.g. Subject field).
- if the auto answered email with the unique number is replied within a week
the original email is forwarded to the meant original recipient(s).
If not the email is "discarded".
- the email users will have the possibility to add sender addresses to the
SPAM avoidence email sender address database.
This email intermediate (filter) could easily be put in e.g. procmail or MTA
Is this a feasible idea to avoid spam?
