@stefano Adoption of #IPv6 isn't a widespread problem any more... (there are some dinosaur #IPv4-only networks, but they're slowly dying...)

But: I'm not fine with what I get from an #ISP as a private consumer. I want the option to have a fixed prefix, I want to be able to get #RDNS delegation for that prefix.

That's why I currently ignore what my ISP gives me and instead use #HurricaneElectric's #Tunnelbroker for my IPv6 connectivity. It's free and offers the features I want 🙄

@murodegrizeco y'know what else is funny?

somebody reverted some (not all! but some!) of our NS ADDITIONAL records at the root servers _apparently_ so people have been getting outdated IP addresses from _two_ years ago for some of our _current_ nameservers even though everything _we_ have direct control over is correct.

this has been a funny day. it's been fuckin hilarious in fact

OH GOOD the reason we're getting a zillion rDNS hits on our not-owned-by-us-for-15-years antique Class C is because the current owners PUT THE OLD INFINITY INTERNET PTR RECORDS BACK UP

Generally speaking, yes.

Here's s great 1 minute script to install #Postfix, #Dovecot, #OpenDKM, #SpamAssassin, etc., Complete with copypasta keys, Etc., And use the MXToolbox .com tools to check your MX RRs, #SPF, #rDNS, and you should be fine sending even to that shithole gmail:

It's a pretty awesome install. Waaay better than all that bloated moocow stuff.

I hope that helps!
