I was recently at an anti-spam conference. I met an e-mail admin
who ran a domain that had been inactive for two years. That is, for
two whole years, the domain "xxx.ca" had NO published MX records, and any
e-mail to anyone at xxx.ca would fail. (xxx.ca is not really the domain;
I obscured it for privacy reasons.)
Out of curiosity, the admin published an MX record for that domain.
He was *immediately* flooded with 100,000 spams/day.
I believe this settles the discussion as to whether spammers clean
their lists.
Regards,
David.
