As of yesterday, Jan. 26th 2009 shortly before midnight (CET), we reached 50’000 active network entries in our database. According to some rough estimate we are halfway there!
Just kidding — it is of coure an illusion to hope to be able to list every mailserver in existence. Already today it is somewhat of a challenge to keep up with daily, regular changes to the existing data (and we are building tools to make that more efficient).
However, I would like to thank all contributors and supporters of the dnswl.org project for their past (and hopefully future :-) ) effort.
