Email supports text.

It's your client that's the problem.

I'm happy in my text only Emacs heaven.

I'm also happy with my custom 5 year old bert based spam detector which hasn't failed me once (unlike whatever gmail at work does).

This post was sent from Emacs.

>Email supports text.

Yes it does. However, I have sent messages to more than a few people who tell me that my message is completely empty. I have my client set to send text-only, no HTML, and apparently the system on the other side drops the HTML version altogether. Something on the other end only processes the HTML part. No HTML, no message.

(I believe these are Outlook/MS based systems, but I don't know for sure. It's certainly not ALL Outlook/MS systems that do this.)

For these people I have to set my client to send HTML. It's all well and good to blame them, but I can't make them do something. They may not even be in a position to do anything. And I don't have an option to tell them "too bad, so sad".

The email situation is really quite bad if you don't conform to the Big Three. I've run my own email infrastructure for a very long time, and it's quite irritating that when we get something good (like DMARC, SPF, etc) it gets forced by the Big Three because along with that we also get things like Google toying with the requirement that you have to have AAAA MX records too.

can you post some details about the spam detector, and just your general setup? I am also an emacs-emailer, using Notmuch, but never looked too deep into the spam story

Have you put this up anywhere for others to use?

Fastmail’s spam filter is not very good.
