It used to be spammers came from far off countries, or all via infected PC's, trojans and viruses, but now the dreaded 'You have opted in for 3rd party offerings' is now King. The major source of abusive email sources being blocked by ISP's is from 'legitamte' email marketing. Users who sign up for a 'free newsletter' or survey are now finding that all of a sudden they get inundated with junk mail. And the worst offenders are from just a few small networks, mostly located in the US, and almost all claiming to be CanSpam compliant. From statistics at several major ISP's it is now obvious that more mail is blocked from US marketing companies than from traditional blacklists. Some of these marketers send 10-40 messages per day, of so called 'legitimate' marketing email. And of IP's being blocked becuase of abusive levels, the majority are coming from local US marketing companies. Most of the traditional spamming techniques now can be stopped at the source, but the companies hiding behind CanSpam and 'opt-in' are now the biggest single source of overhead at ISP's and Telcos'. A new listing of such offenders has been made available, at MIPSPACE and ISP's who have chosen to use this list are finding it the only way to protect their users from the abusive level of email marketing. What ever happened to being able to call the post office and just saying, 'No More Junk Mail Please'"
