Decentralized SMTP is for the greater good
- SMTP is the way computers exchange e-mails
- it is a decentralized protocol meaning that ANYONE can run a node and be independent
- it is being centralized at companies that have a history of abuse
- it is being centralized in a country that has a history of abuse
Blacklisted by the big mail providers, yes.
I contact the users that I have problems reaching and I explain the situation, and I offer them an account on one of the mail servers that I operate. That works in approx 50% of all cases, and these people are happy to leave the GMails and Yahoo.
We need more "community" ISPs that provide essential Internet services (mail, web, chat, social media) for their communities and are run by people from these communities.
@cstrotm I feel called out by this (since it's what we had been doing 20 years ago), but every time I bring up the topic nowadays I'm blocked by the likes of "email is dying anyway" and "the cloud providers are better at running services, why even bother"...
>I can reach almost any port 25 in Germany

> Outbound Email Policy of Deutsche Telekom AG for this IP range:
> Deutsche Telekom advises against accepting e-mail from dialup IPs. We provide these IP addresses dynamically to our customers for internet access. Proper e-mail delivery should use dedicated servers, which is why attempts of e-mail delivery from dialup-ranges generally can be traced to compromised computers or other misuse.

Yeah but its a pain in the ass to convince your ISP to create new reverse DNS records :/. Which also means both Google and Microsoft simply blacklisted my fqdn and my ip in the meanwhile
