Well, some mail providers act like complete idiots. That has nothing to do with E-Mail as a technical thing.
Want a real word example that happened to me a week ago?

T-Online (Telekom) blocked my personal locked down (accessible only to me and a couple of people I know in person) mail server because I didn't send a mail to t-online addresses for a long time. That made them conclude my address was dialup. This was their "reason" for blocking me.

Sending too much mail -> blocked. You are a spammer.
Sending too little mail -> blocked. You are a dialup even though obviously you aren't.

I do implement every technique needed for modern mail delivery on my system.
That and explaining and proving to them that my system was not dialup and was private and low volume did not help.
They forced me to disclose my private home address in public to fulfill their idiotic corporate processes.

This has nothing to do with E-Mail being problematic.
This is purely caused by idiots doing idiotic things.
Just like AI crawler responsible persons do.

They also now want you to host a website on the domain in your server IP's reverse DNS entry that has some sort of redirect to a website with a contact form for them to use in case of abuse.

I am certainly not going to run a webserver on every single server I run under the server's hostname (which is deliberately chosen to not be any of the services it hosts to make migrating those services easier) just because the T-Online mail admin team is too incompetent to use the abuse@ addresses like everyone else.

T-Online? Germany?

If you start getting spam to that address file a formal complaint under your equivalent of the GDPR, that they leaked your private email address.

Dunno how many legs it has, but given the circumstances any reasonable regulator *should* conclude that they clearly breached the regs.

(Although whether said reasonable regulator actually has sufficient brain cells to *understand* the complaint is another matter...)
