    Gregory,

    there is a vulnerability in your solution... (sorry, couldn't resist :)

    I have that guy on my filter list as well. However, when people reply,
    those messages are still received. (I'm not filtering on Bipin anywhere
    in the message since I don't want to risk false positives..... perhaps I
    should try it for a while).

    Luckily there is the option to filter a certain subject temporarily. And
    I guess that means I won't see my reply either...lol...

    Cheers,
    Frank
