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?
