I have been using email for 40 years. It used to work.

As an (independent) academic researcher, I need to contact new people, primarily in universities, to ask questions.

I refuse to use Google, Microsoft or the other American IT giants.

But they are increasingly preventing refuseniks from sending email at all.

I know what RFC, DNS, MX, SPF and DMARC mean. My email goes through small British companies with intelligent, friendly and helpful staff.

mxtoolbox.com says that I must have DMARC to send email to M$. So I set it up. I now get a dozen copies of the same report from G or M$ for each email that I send out.

They show that my email gets to G and M$ sites, but then it is marked as spam.

The stupid senior management of numerous universities has surrendered their staff email to M$.

Web searches and AIs preach about spam. I don't send spam - I want to contact my colleagues.

Rumour has it that previously unknown senders are treated with suspicion and their emails are sent to spam. In other words, it is impossible to **initiate** communication with someone.

Let's be blunt about this. They are a mafia that is enforcing an **oligopoly**. It's got nothing to do with reducing spam --- I have no doubt that they let through emails from "trusted partners", ie companies that bribe them enough to send their spam.

The result of this is that it will only be possible to send emails by paying M$ to do it, and then it will only be allowed to express "approved" opinions.

What can we do about this?

At the very least, those of you with senior positions in universities can tell your management to revert to competent standards-based email systems hosted on Linux systems.

@Paul_Taylor I run a self hosted mail server. It's kinda hard to get right, but the requirements seem absolutely reasonable and you can fulfil them.
I don't really see them abusing their market power there ... just yet. (I think they are just waiting for email to die the natural death)
@helge @Paul_Taylor no, they're actively taking steps to strangle it. we fulfil the requirements but none of our mail gets through because we aren't big enough to register any reputation in their system.
@atax1a @Paul_Taylor That seems weird, I didn't have issues so far. If the DNS is setup right, trust is essentially granted?
@helge @atax1a @Paul_Taylor sometimes yes, sometimes no. basically the problem is that in order for your mail to have a high chance of not being flagged, you must have a good reputation. to get a good reputation, you must prove yourself by sending a bunch of not spam, slowly ramping up the rates.

this doesn't work for small, personal servers because you simply just don't have that much mail to send.

if you get lucky, you might be fortunate to have an ip with good reputation and not have to deal with that
@stag @atax1a @Paul_Taylor My feeling is that for getting a bad reputation you really have to be on a very fishy provider.
In the particular case of the original poster it seems to be a clear miss on the DKIM requirement (which is reasonable). Nothing reputation related.
@helge @atax1a @Paul_Taylor generally from my experience big tech's spam filters will always reject any email from residential ips and reused cloud ips (like those you would find from aws or gcp)

i've had better luck with other providers like hetzner, but it really is a hit or miss
