OT: _spam_ (Fred N. van Kempen)

Two things.

[0] I'm still working on that ol' web site thing for ClassicCmp. One thing
    I'm looking at now is integrating the old archives with the new
    archives, which I've found *is* possible. More importantly, I now know
    how to spam-protect _every_ address in an archived message -- not just
    the poster's address. DUH, it's called *sed*!

        sed -Ee '
        s/([^[:space:]]+)_at_([^[:space:]]+.[^[:space:]]+)/\1 [at] \2/g
        ' < bad_file > good_file

    That replaces the '_at_' in email addresses with ' [at] '. Is that
    sufficient to fool a harvester, or should a more sophisticated
    replacement be made? What replacement would that be?

[1] I've written a procmail script that makes unknown senders go through a
    confirmation process similar to subscribing to a mailing list. I
    established backdoor, unfiltered addresses that I will hand out to
    companies, one for each business that wants one. That way, if spam
    starts coming to a particular address, I'll know exactly who is
    responsible and take appropriate steps.
