It's well worth 90 euros. You get a permanent site license to use on all
systems on you site and free updates :) I haven't fond anything else with
the same features and as reliable for free.
If you bought Milter-ahead 1.0, 1.1 is now available for free download for
the Snertsoft site www.snertsoft.com
