It's always people self-hosting mail on a shared server in Moldova (because they think it makes them cool) that are complaining.
Which with cheap models like Jev as spam classifiers, this can now become a reality.
The problem is, Google and Microsoft have monopolized the entire email market, so their esoteric deliverability mysticism from 2007 still persists (basically blanket bans on entire IP spaces, locking out anybody trying to send emails on their own).
Email naturally followed this evolution.
Switch Moldova to almost any country (or even a state that isn't California or Washington), and it's the same story everywhere
You shouldn't own your car or your house, give them to all the corporations as well.
As soon as you want to do business with Outlook's customers, you play by their rules.
"They're allowed to do it" is one of those things that doesn't really bear saying so much because that's already been implicitly established. Nobody is claiming what they're doing is illegal, so how does this add anything of value? Who is still unaware that corporations will use their size and market control to their benefit?
"Their rules" seems to be turning into "you spend money to another corporation that we trust".
I've never even had the key to mine. I've lived here over a decade.
With LLMs on the other side trying to make spam less detectable by cheap models like Jev?
It's funny when people assume benefits from some tech go one way and baddies will surely never use it...
