You can actually get away with one static IP. It's ill advised. But it will function. You can also have external 3rd party secondary DNS servers that pull from your (private) primary DNS server. You might even be able to get this communications over a VPN if the secondary DNS server operator is cooperative. > Once running I'll find a similar bandwidth usage organization and swap > DNS secondary services. That's a nice idea. But I've not bothered with that in about 18 years. I have Linode DNS servers be secondaries for my domains and point the world at them. I'm still in complete control of the domains via my personal primary DNS server. Note: I'm not offering reciprocal secondary DNS service. This is trivial (for Linode) perk that I get by being a customer for other things. I think a single < $5 / month VPS qualifies me. (I don't remember if there is a lower tier VPS or not.) > Now days with all the issue wit CA and others similar/related > issues. that might get complicated. Don't let those features blind you, especially if you don't want to use their features. Also be mindful of ascribing credit them if they are simply front ending something like Let's Encrypt, which you can do on your own for free. > (2) static IPs for (2) dns primary resolvers should get me going. 1 static IP somewhere will get you started. ;-) > Verizon killing its email services: > > https://www.inquirer.com/philly/blogs/comcast-nation/Verizon-exiting-email-business.html I'm not at all surprised. > Well, it's probable not appropriate for me to "finger" specifics.

Sure, they are influencing who they are used with, and in some cases /not/ used with. But, thus far, the underlying technical standards have been the same. > But someone like you (Grant) could help guide and document a gentoo > centric collective that provides for email services, secure/limited > web servers and a pair of embedded/DNS (primary) resolvers so we can > keep email systems alive. A couple of things: 1) Nothing about what I'm suggesting is Gentoo, or even Linux, specific. The same methodologies can be used on other OSs. 2) I don't think that email is going to die. It certainly won't do it faster than Usenet has (not) done. (Usenet is still alive and quite active.) Yes, email is growing and changing. But each and every one of us that thinks about running our own email server has a tiny bit of influence in that through our actions. > Thanks  for your insight and suggestions.
