Have you sampled those other 2000 messages to see how many of their sender addresses are of free providers, perhaps by checking my list of free providers implicated in spam sent my direction? I bet that if you did, you'd find that many of those 2000 are other free providers. The 823 messages in your top 11 domains involve free providers. If I'm wrong and none of the 2000 other messages involve free providers, you still have 25% of your sample of 3300 coming from 7 domains that share a common characteristic. Judging from your top 11, those other 2000 messages cannot involve fewer than 76 domains, so 25% of your sample is coming from at most 8% of the sampled domains. I bet you have more than 500 domains among those 2000 messages, so that the 7 free providers are about 1%. What are the odds that is a coincidence? I'm far from unique in blocking free provider mail. If you need to pick a domain to forge for spam, a free provider is a terrible choice. What explanation is there except that spammers prefer free providers for good reason? What can the reason be that except that many spammers are not forging free provider names? > Your are incredibly hypocritical to be blocking those free domains that RMX > could make usable again.

Why don't you install the standard hack that blocks mail that violates the primary RMX criterion? Why wait for the free providers to change their T&C and install RMX RRs? I don't recall any contributor to this list admitting a shred of ignorance or doubt about spam, so like all of us spam experts, you must be familiar with the standard, many years old advice to block free provider mail that does not come from the free provider's MTAs. It does have a high false positive rate except in trivial situations like mine, but it does not block any mail except what you term "spoofed." My vague recollections are that the hack is easy with postfix (which you seem to use). It's bound to be quicker and easier than RMX. I'm sure that practically all free provider users are innocent of spam, but that's none of my business. They are free to send mail however they want without any criticism from me if they follow their ISPs' terms and conditions. It's simply that they can't send mail to my domains....well, I do urge friends to not use the free providers. Some of them ignore my advice and force me to add whitelist entries if I want to receive their mail. I usually do, but not always. I don't use the hack of the standard advice mostly because simply blocking the free providers is easier and just as good for my situation. The observed probability that an message with a free provider sender address sent to my MTA is spam is more than 99.9%. I do not expect anyone else to do that blocking for me. I also do not expect the free providers to change their T&C so that they could use RMX or to eventually use RMX, or do anything else. I think demanding that free providers change to fit my model of how they should run their businesses to suit my convenience would be wrong.
