I agree with everyone here that self-hosting email is never easy, but if you still decide to go down this route then here are two tips that I personally found very helpful, especially when you decide to host it at home:

The first is to get an SMTP relay server. That’s just another mail server that yours can log into to actually send its mail, just like an email client would. That way you don’t have to worry about your IP’s sending reputation, because everyone will only see the relay’s reputable IP.

Second is to configure a Backup MX. That’s an additional MX DNS entry with lower priority than the primary, and it points to a special mail server that accepts any mail for you and tries to deliver it to the primary server forever (or something like an entire week). So when your primary server is unreachable other sending servers will deliver mail to the backup, and it delivers the mail to the primary as soon as that’s back online.

You can get these as separate services, but some DNS providers (like Strato for example) offer both with the base domain package. It makes self-hosting an email server much simpler and more reliable in my experience.

Welcome to the Linux community. :)

You will probably never understand everything about Linux and all of its included and associated systems. That’s completely fine, no one does! That’s why we are many, and it’s what asking for advice or help is for. You can just learn whatever interests you at your own pace, and know that there will always be interesting things you haven’t seen yet.

I’m transcoding everything to 320kbps MP3s. It’s much much smaller than flac, and I can’t hear the difference even if I try.

Fedora, I usually wait 1-2 weeks for the last bugs to be found+fixed and extensions to catch up, and then just upgrade in-place. Haven’t had a major upgrade problem for years now, it’s mostly as smooth as any other offline update. And I don’t feel like I have to reinstall the OS every few years on Linux either.

united, indivisible republic

So no federalism anymore, just one centralized state power.

All baronial and other feudal estates, all mines, pits etc. shall be converted into state property

The mortgages on peasant farms shall be declared state property

All private banks will be replaced by a state bank

All means of transport: railways, canals, steamships, roads, posts etc. shall be taken in hand by the state

So the state owns and manages all land, all finances, all infrastructure, and all means of mass transportation, on top of all the things the state controls already.

Idk what you think centralization of power looks like, but imo this is it.

Because that’s what creating an all-powerful government leads to. Imo the key is splitting up and balancing the power, not concentrating it in one easily corruptable entity.

One of us One of us One of us! :)

No! I prefer ______, and you are WRONG for thinking otherwise!

No, it really doesn’t. That’s like creating a bot that buys and sells company shares automatically, and saying the stock exchange has a vulnerability because your bot makes bad decisions.

I just set up a Vouch-Proxy for this yesterday. It uses the nginx auth_request directive to authenticate users with an SSO server, and then stores the token in a domain-wide cookie, so you’re logged in across all subdomains. Works pretty well so far, you don’t even notice it when you’re logged in to your SSO provider.

But you do have to tell the proxy where you want to redirect a request somehow, either by subdomain (illegal.yourdomain.com) or port (yourdomain.com:8787) or path (yourdomain.com/illegal). I’m not sure if it works with raw IPs as hosts, but you can add additional restrictions like only allowing local client IPs.

In my special case I’m using the local Synology SSO server, and I have to spin up an additional nginx server because the built-in one doesn’t support auth_request.

What’s absurd is this crypto maximalist take.

You can’t just make up your own permission and punishment system, and then expect the legal system to just step aside and let it handle all disputes, especially when it comes to fraud. That’s like founding your own city in an existing country, and declaring all existing law obsolete. I know some people think this is a real possibility, but the real world doesn’t work like that.

IANAL and all, but bad/unfavorable contracts and literal deception/fraud are two different things, at least in the legal system. Not everything that’s technically possible is also allowed, obviously.

Compare it to using a security flaw to hack into a system. Technically you’re only using the official API, maybe in unusual ways, but still. But you’re doing it in bad faith and causing harm, maybe pretending to be someone you’re not or injecting fake data into the system, and that can make a difference.

It’s not. They tricked some MEV-Boost bots into doing bad trades.

Here is a more detailed explanation of the exploit.

The Pepaire-Bueno brothers exploited a bug in MEV-boost’s code that allowed them to preview the content of blocks before they were officially delivered to validators, according to the indictment.

The brothers created 16 Ethereum validators and targeted three specific traders who operated MEV bots, the indictment said. They used bait transactions to figure out how those bots traded, lured the bots to one of their validators which was validating a new block and basically tricked these bots into proposing certain transactions. […]

So hardly an attack on any core system of cryptocurrencies.

Why stop half way? All you need is a benevolent dictator, shouldn’t be too hard to find, right?

Some of these points are good, some are just absurd. Letting “the state” handle everything and hold all the cards, and then actually believing that it won’t be coerced and corrupted or that there won’t be strong disagreements about how to handle things is just delusional and wishful thinking on a grand scale imo.

I agree that most modern countries need to strenghen the public sector, but you still need checks and balances between powers, individual responsibilities and freedoms, real-world economic feedback and incentives, and so on.

I hope at that point we have enough capable alternatives. Like, hopefully around the time they add ads is also the time when open-source models and apps have caught up again.

You have to provide the user, group and file name as the next three guesses, just trust me!

They could just choose someone to send to the debate, doesn’t have to be a candidate for the presidency.

I’m no fan of the right, but some of the rules only exist to prevent smaller alternatives from getting traction, especially in the media.

It’s a group therapy called !linux@lemmy.ml, we always have free seats!

This is pretty impressive and hella creepy!
