I know, many advise against it. But it does not matter, I just want to try, not (yet) host my important e-mails.

So it seems that by default port 25 is blocked by the internet service provider(s?). So I asked my provider to open it, and they answered that as per Trafi rule, port 25 is reserved for the ISP and the ISP only, not to be used by private consumers.

The customer service could only give me this link, which does not explain why this port or the others are blocked. I also lack the technical background to understand this decision.

Can someone explain to me? And are there ways around it without using a VPS? What is/are an association for the defense of digital rights here, that would have content in English?

Thank You!

Having an extra VPS is not going to be cheaper since I already have email capable infrastructure. And I have read in Lemmy of people self-hosting email without issue. So it must be a reasonable expectation that it might be possible.

A VPS is usually cheaper than a business ISP subscription and you'll also have to already have a company or register a new one with PRH. I have a company and do most of services out of my home. You can't get any pricing without contacting sales, but for the same home even on the same DNA or Elisa or whatever their business side is going to be more expensive.

I'm not saying it's good. I'm in the same boat of paying for a VPS just for email and hosting everything else at home. Just knowing it's not right doesn't make it not be like that.

That's some valuable info. I would still like to know more about who took that decision, when and why, and what I can do about it / how can I express my concern.

Could be summarized by e.g. who should someone NOT vote for and is there a digital right association people can subscribe to.
