    Back in the dark ages of email delivery the only thing that really mattered to get your email into the inbox was having a good IP reputation. If your IP sent good mail most of the time, then that mail got into the inbox and all was well with the world. All that mattered was that good IP reputation. Even better for the people who wanted to game the system and get their spam into the inbox, there were many ways to get around IP reputation.

    Every time the ISPs and spam filtering companies would work out a way to block spam using IP addresses, spammers would figure out a way around the problem. ISPs started blocking IPs so spammers moved to open relays. Filters started blocking open relays, so spammers moved to open proxies. Filters started blocking mail open proxies so spammers created botnets. Filters started blocking botnets, so spammers started stealing IP reputation by compromising ESP and ISP user accounts. Filters were constantly playing catchup with the next new method of getting a good IP reputation, while still sending spam.
