    Hi guys,

    I downloaded the latest, but couldn't get it to run. So I rewrote it as an inetd/xinetd client instead. But that is not my worry....

    I think that there are several types of spammers, and at this point I am catching close to 98% correctly of the 300+ emails I get every day.

    However I find this approach intriging, hence the interest.
    I would like to know your statistics on why you are not forwarding the initial emails.
    I have only been running for 12 hours or so and the 2 emails I have received so far indicates solid tests for open relay. Not just a blind poke.

    As I see it there are several types of spammers:
    1) those with a blind machine just using an open relay
    2) as 1), but using real relay tests
    3) those using their own MTA

    In my spam approach, I actually connect to the remote MTA to asses if it is a SMTP server of some kind. And some of the spammers do use this approach, which can not be caught using honeypot approach. But that is beside the point.

    I really think it is necessary to forward the initial test emails, but you seem to have statistics for that. Enlighten me please.

    Merry Christmas,
    Karsten
