After I posted, I finally pulled the thumb out, and did a google
search - one hit on the search term "Millions CD" (which might be some
spammer's trademark - I dunno) returned a site selling 15 million "Fresh"
addresses on a CD for US$249. I imagine the price is justified by the
'de-munging' (really, anyone who knows 'sed' can eliminate a lot of
the common stuff), checking domain validity, and then removing addresses
of those anti-spam activists - whatever that might mean. Thus, it
appears that these harvesting services might be ignoring old, but unused
names. But yes, I remember the "good old days" - when things like Rob
Clark's 'Winmodems' web page (referenced in the Modem-HOWTO) used to have
working addresses so you could contact someone who had actually gotten
some particular model of modem to work. I was listed on about 8 models,
and used to get a couple of mails a week asking how I got this or that
modem to work. That was a useful service the spammers killed.

The only catch-all accounts I still have are 'abuse', 'hostmaster', noc'
and 'postmaster' (per RFC2142), and even they are filtered - postmaster
less so, but still.

Like you, I haven't heard of any false positives, but I don't bother to
keep track of numbers. I don't even turn on the logging that often.

There was a very interesting post to news.admin.net-abuse.blocklisting
in a thread titled 'Effectiveness of DNSBLs declining?' from Matthias Leisi
on Saturday evening (Message-ID: <d6oh43-b2r.ln1@msgid.astrum.ch>) with a
pointer to a paper he wrote analyzing a spam run. Some of the conclusions
are not new, but the insights are quite interesting.

I still can't imagine why people think that might be ordinary. Likewise
the crap claiming to come from eBay, PayPal, or "my" ISP.

Mine originally was even signing the advertising and information bulletins
they were sending out - then they wised up and provided an 'opt-out' to
that stuff, shifting it to 'standard' mail (the definition now used by
the US Post Office for what used to be "bulk mail"), or 'first class'
mail if it's important. Using snail-mail costs real money, so they are a
lot more selective of what they send out.

If they can't get the hash off the backup tapes... (you can tell the
plishers have no central authentication system experience - wonder if
their windoze box is using one of those passwords the 'deloder' worm was
testing for in March of 2003)
