The application installed painlessly on my Macintosh, and was fairly easy to set up.
I REALLY like the addition of being able to lookup Japanese abuse addresses.
I really like the ability to customize the message that I send to the ISPs with the abuse complaint.
I like that it also includes the other domains involved/listed in the message header to alert the admins of these domains about open relays, and spammers spoofing their domains. That combined with the customized message I think will help get the domain admins involved.
I want my buttons back.
I'm guessing in the release version you'll have automated processing turned on??
