Extinguishing rule
(infosec.pub)
Be sure to follow the rule before you head out.
Rule: You must post before you leave.
Email is not independent and hasn't been for a while. Go ahead. Try to run a mail server of your own. If you aren't paying one of the big companies, your email won't get delivered.
it's not that bad, really
like 80% of US ISPs block port 25 outbound. you're not gonna be sending emails without going through some additional commercial entity forwarding that traffic.
sure, find a VPN provider that provisions PTR records correctly, and it's not too hard to get your mail delivered if you read the docs. it's also true that that's notably more restrictive than any other "open" communications protocol i'm accustomed to.
