Lovely, running my own email server could be punishable by jail time. And people bitch about the continuing consolidation and centralization of the Internet ...
You're welcome to run your own insecure email server, but don't expect other mail servers to connect to it, or accept connections from it.
Also, don't allow other people to send or receive email from that server unless they have given you their informed consent that it does not meet the basic industry standards for security.
Sure, and servers should refuse to connect and deliver mail to gmail.com addresses without consent from the recipient that their email can be read by Google employees and any government with the jurisdiction to compel them since they don’t offer email encryption.
Your definition of “basic industry standards for security” is not the same as others who are serious about security and it’s not the same as people slinging birding newsletters.
The fact that legal action to fit your taste is being suggested is pretty tone deaf.
First, the parent said nothing about jail time. Unlike what many Americans think, incarceration is not the only penalty that can be imposed by the government.
Second, there are already legal penalties for certain types of misconfiguration. For example, if you run an open proxy, or public file server, you could already be punished for transmitting or storing illegal content. However, most governments worldwide have at least a modicum of sense, and do not mete severe punishment (e.g. incarceration) for obvious mistakes.
