BL test wanted in New Feature Request Posted April 5, 2006 For example, spamhaus.org has such test. This isn't difficult to release, the price is losing one IP only. It will help to avoid many messages from users like "I have set the BL up, but it doesn't work!". Really if I still get a spam, what is a reason? The sender's relay was not listed at receiving time, or maybe something is wrong in my setup? Hard to diagnose.
