[BBLISA] Mail forwarding providers?

[dean.anderson71 at yahoo.com]

That's a flaw in spf, dkim. They don't anticipate forwarding.  But spam is just a scam by "antispammers" and always has been. While there are some naive people who try to fight spam and aren't ripping people off, I discovered ORBS abusing open relays in the 1990s (before SMTP auth invented). When I reported this to the antispam community, well, let's say it wasn't well received.  I was blacklisted from nanog.  I thought that was a strange reaction, so I started digging and thinking about spam.

I discovered that information theory prohibits a solution to spam. Spam is always a whack-a-mole problem. Communication systems can't be made free of a covert channel. Spam is a kind of covert channel one tries to suppress.  

Then I discovered that Vixie and John Levine were partners in a spam company that offered "list washing" services--that is, they would take spam-trap addresses off their mailing list.  That information was even more badly received, and I was blacklisted from ietf. 

Then I found Vixie running things at ARIN, without getting election quorums. And trying to sell "protection" to legacy holders. I found myself blocked from Arin member lists.

So, it's a scam. Antispammers send the spam and charge protection fees.
