So many people believe that spam filtering is "simple" but we all know it's anything but.
There's blacklisting and whitelisting, each of which are pretty straightforward, but it's the feedback loops between the major email service providers when they think they've trapped something that comes from, say, an email subscription service that's hard to concisely describe.
I'd love to have something reasonably comprehensible, even if overly simplified, that makes it clear that the email service providers use very sophisticated methods, some of which will think something is spam, but will then communicate back with the service that sent it and where that preliminary classification might be reversed.
A good example of this is the "You're being bounced" message members can receive from the Groups.io subscription service. Based on what I know of these, they seem to be notifying the recipient that messages being sent to a member from Groups.io are bouncing back. They always contain a link that you can activate to "unbounce" yourself, which restores email flow, at least until the next cycle occurs. This suggests to me that when the user uses that link, that a feedback loop is established where the user is telling their email provider, and Groups.io, that email received from Groups.io is not considered spam by them. Maybe I'm entirely wrong about what's going on behind the scenes.
But if there's a place to ask about the arcane aspects of email spam trapping/filtering, this is it!
