SMTP ain't dead, it just smells funny.


There is a simple way to make spam a thing of the past. It only requires two things;

  1. Mailservers should only accept mail which is 100 % RFC compliant. All other mail should be rejected (not bounced).
  2. The use of MS Windows in networks (incl. the internet) should be banned.

A note on the use of blacklists

WARNING! The quality of DNS-based and other blacklists varies a lot!
DUL-lists for instance, are supposed to list dynamic IP addresses, but often list static IP addresses as being dynamic. So it's best not to use DUL-lists.
Some lists publish entire /24's instead of individual IP addresses. Don't use these blacklists either (it is OK to list entire IPv6 /64's though).
Some lists delist automatically. Others require manual delisting. The latter will result in more false positives.

These may include snail mail spam, sneaker spam (sales / market droids calling at your door), phone spam (telemarketing) and horizon spam (over the top billboards).
