if I have communications with someone through the internet with a homeserver. I would inevitably give out my IP address. Is that a bad thing? In my country they don’t have services like that, RTCing would be a bit sluggish using available euro servers.
Many ISP block the necessary ports outright to prevent someone sending spam. But even if not, rDNS is usually not supported and in general it is almost impossible to avoid being sorted out as spam by the large email providers.
So the only issue is that you can’t send emails to people using those providers?
In the best case yes. Although there are some providers that allow you to proxy outgoing SMTP connections through their highly trust rated servers. But that at point you might as well get a cheap email with your domain provider and only host other stuff from home. Less hassle.
This and also you end up leaking your IP
And? isn’t this entire thread about “leaking” IP being not such a big deal for most people? You can always run a VPN on your home server if you want to “hide” it when not at home.
If you have a dynamic IP is your IP leaking even a problem?
That doesn’t really make a difference I think.
I’ve been wondering about this on-and-off for years.
What if I didn’t give a shit? Like, maybe 1% of my gmail emails are complete garbage. Of those 1%, absolutely all of them are responses to account signups or online ordering off of big websites. For those, I could continue to use my gmail account.
But, at this point, email’s almost worthless for real communication. If I wanted it to be for real communication, why could I not set up my own email server that is configured such that it blocks all non-encrypted emails received? Just bounces them outright. This means that it instantly becomes a zero-spammable service for me. And the dozen or so friends/family I might want to receive emails from can just get accounts on it.
I understand (and want) it to be isolated from the greater email system. Is this possible?
And if others wanted to (for shits and giggles? dunno) become part of it, it’d be as simple for them to set up similarly configured email servers. You could even test them automatically that they were following the rules… send an unencrypted email to it, and if it doesn’t bounce just blacklist them.
I guess there’d have to be some sort of public key infrastructure for it, no idea how to do that.
I actually very seriously considered setting up a one way email to xmpp forwarder with a generic auto-reply informing people to just stop sending me email :-/
Other then for work, which is basically also not real email anymore, but something that looks like it, but is mostly contained to the MS-Teams / Exchange world, I basically never send any emails anyways.
