    Challenge Response

    Well this is my first post so I hope you can all help me out a little!!

    I am interested in setting up challenge response, in a bid to overcome the huge amount of spam that we seem to accumulate everyday. Has anybody had any experience with setting up and using this?

    Any information would be much appreciated.

    TMDA is one way to do this.

    That being said, please don't. Challenge-response email systems (and more generally, anything that automatically sends a response to email messages) are obnoxious, as has been demonstrated to everyone with an email address by the MyDoom worm.

    I can only agree with dan_erat - please don't do it. It adds to the email load and you run the risk of getting yourself on a blacklist by being reported for sending out emails in response to worms that forge email headers.
