Dearest Spammer,
Sending a message to all cpan.org addresses will not get you customers. Even if you are pushing a perl related product and not penis enhancement drugs. You are now blacklisted by us and hopefully listed in spamcop and other blacklists. Do not expect it to be removed unless you bribe us in a big way. I only wish I had caught your spam before you sent it to over 600 addresses.
Sincerely,
me.
