"Run Your Own Mail Server" by M.W.Lucas

You could be a nasty proxy
Yeah, or an alien from outer space.

Lots of things "could be". The interesting thing is the amount of collateral damage that is accepted to achieve... btw, to achieve exactly what?

You remember gold and oil? People aquiring a claim and starting to dig or drill? If anybody else would step on your claim, you would just shoot them, no questions asked. Exploitation is everything.

So that's the same now, exploitation is everything, and anybody else might be a "thief" and can be shot without asking. A shark's pool.

The main difference is, what is the thing to be exploitet here? What is the produce? Answer: the produce is now YOU, the users. YOU are to be exploitet.

US America is built on the foundation that it can only exist by exploiting others. Traditionally it was other people, other cultures, or mother earth. Now it is us.

(This is, btw, the reason why D.Trump is such a dangerous man: he endangers this very foundation, because he wants America to care for it's own people instead of exploiting others.)
 
I simply stated that a fixed IPv6 could be a nasty proxy. Nastie proxies could alter google's search results. That's why you are getting the annoying captcha. Think how many fake searches I could conduct using a /64

I don't know what You think a "fake proxy" is. But a search is a read-only operation, it does not alter anything. And if google fears they get too many queries, then the could simply limit them, instead of doing prophylactic harassment.
 
FWIW, in the video linked MWL suggests getting a /64 IPv6 address block to make life easier for self-hosting email as a way to reduce getting stuck with an IP in a blacklisted block.

That's true - but then where do you get reverse DNS for the IPv6? (Except from HE, which do not allow port 25)
 
I'll let you know once I've received the book and had time to read it. :)
That's cool.
I thought there were some experiences about how far we get setting up mailservers. Or, we might even share these experiences, like we did in the old times.

Instead, there is now only sharing about which things (clothes, cars, books, ...) one is supposed to buy. But that is indeed very much to the point - why you should watch advertisements in a 24/7 fashion, why you should receive your mail at a place where you can get sufficient advertisements, or why you should have your discussions where there is ample advertisements.

When I set out to run my first unix machine in 1989, I went to the bookstore and tried to get a book (the software was stolen, there were no docs). But there were no books either.
Then, people started to meet at my place every friday evening, and we shared our proceedings and how far we had gotten.
 
"... But a search is a read-only operation, it does not alter anything..."
This is rather naive imho. If you google something, and I google the same thing, we get different results, different ads, different marks in our google profiles and the keywords searched get updates too, it alters things a lot.

With IPv6, the whole /48 or /64 will simply get blacklisted. Not the single IPv6 address as it initially would for IPv4, but mess around with that and you'll see your IPV4 block getting banned, listed etc.
 
Comcast/Xfinity is my ISP, and no servers allowed on their wire, unless paying ludicrous "business" rates.
Years ago, I hosted my own mail server (still own the domain).
I got endless spam, and wound up blocking entire continents (Europe, Asia, Africa, etc)
It was a giant PITA.

For blocking there are blacklists accesible with DNS (DNSBL). Spamhaus offers such lists:


There is for example the sbl, xbl, pbl, sbl-xbl, and zen list.

If your IP is for example 178.215.236.107 (a spammer attacking my server), you can consult zen list manually with
drill 107.236.215.178.zen.spamhaus.org

Well, sendmail may consult a list and act accordingly with a config like:
FEATURE(dnsbl, `zen.spamhaus.org')dnl

With zen, I cannot use a mail client at home to send a mail with smtp to my server, I just downgraded to sbl-xbl,
but look:

A lot of people are using our SBL and XBL lists to guard their mail infrastructure against the incoming floods of spam. While we encourage all SBL-XBL users to switch to ZEN to check the connecting IP, the SBL-XBL combination still has a very powerful, but lesser-known application area: use it against spamvertized URLs in the message content.


UPDATE:
I discovered that I can still use zen list and my client if I whitelist the IP of my client in sendmail's /etc/mail/access with
something like

Connect:178.215.236.107 OK

(Do not do it with that IP, it is a spammer!!!)
 
This is rather naive imho. If you google something, and I google the same thing, we get different results,

Ups. If you and I ask the same question, then absolutely and naturally I expect there to be the same answer! That is what's called honesty.
Is it now "naive" to expect honesty?

different ads, different marks in our google profiles and the keywords searched get updates too, it alters things a lot.
But that is then intentional manipulation, that is designed brainwash! That is NOT providing honest information about what resources are there on the Internet. It is rather steering and controlling the people by feeding them manipulatively crafted input!

Then the actual problem is that Google treats the people like they were cattle in Google's possession, and Google fears somebody might, by issuing queries, somehow disturb their cattle (which they think they own, and therefore only they have the right to manipulate - just like any stock farmer does).

So lets get around here. In the recent years there was a lot complaints by the establishment (to which Google certainly belongs) about certain people distributing what is called "fake news". But what You have just explained, is, that Google's business is based on the distribution of crafted manipulative information, or in short, fake news. So the problem with these fake news is in fact not that they get distributed, but that they are not in accordance with those fake news that the establishment wants distributed (by Google et al).

Now if You think this is all fine and normal and anybody who expects more honest practices is "naive", then that is your part. I for my part know that there is a proper word for such proceedings - that is feudal socialism (which is practically the same as national socialism, but on a global scale).
 
Do you not see a problem with IPv6 here? Also
If You see a problem there, then that is fine with me. I don't see problems with privacy, at all (we get to that, soon below).

I for my part am happy that IPv6 gives me back what did exist in the early days, when every coffee maker on the campus had it's IP and was globally reachable. So now each and every of my gadgets is globally reachable again. And I am not using EUI-64 anywhere, I'm just starting to count addresses from 1 and then up thru the next 2^64-1 numbers - as simple as that.
Having an address like fd00::35 is a lot easier to type that lengthy EUI64 stuff.

Now about privacy. It just doesn't exist anymore. It has gone 25 years ago. Back in the 80s/90s we went to the street for privacy, we went to the street against governmental census. It made sense back then, because we did care for our own stuff and didn't want or need the government to interfere.

This whole new concern about privacy nowadays is simply orchestrated: the conductor tells you cattle to in-chorus moo about privacy, in order for you to meanwhile ignore that 1) there is no privacy anymore, and 2) the real concern wouldn't be privacy, but rather systemic manipulation and instrumented brainwash.
To put the well known stance "what use is a phonecall if you cannot speak?" a bit differently: "what good is privacy if you're remote controlled?"
 
For blocking there are blacklists accesible with DNS (DNSBL). Spamhaus offers such lists:
In theory, it should be possible to get off such a list - if for instance you have aquired some IP, and find it on a list.

In practice, in my experience, that went flawlessy with the 0spam.org list - but others do not react at all, or apparently even try to extort ransom for being put off the list.
 
Do you not see a problem with IPv6 here? Also
BTW, what is also wrong in that article:

Back in 2007, IPv6 privacy extensions were proposed to randomize the host portion of the address. And ISPs got into the habit of rotating IPv6 address prefixes as an additional privacy defense.

Thats bogus. They rotate them in order to charge a premium for not rotating them, i.e for so called "business plans" where you can run a server. For the sake of "privacy" they would need to rotate these network prefixe rather often, probably daily, but that's not even possible, because every such rotation would interrupt the ongoing voice-calls. In fact for instance my provider rotates it twice per year - which has nearly no benefit for privacy, but still makes it unfavourable to operate servers.
 
I simply stated that a fixed IPv6 could be a nasty proxy. Nastie proxies could alter google's search results. That's why you are getting the annoying captcha.
There is actually scientific research that tends to the conclusion that these captcha have in fact no benefit whatsoever in protecting from any abuse. They are rather a means of extracting unpaid labour from the users, the results of which can then be sold.
Also, the fact that the captch consists mostly of detecting traffic lights, crosswalks, bicycles and motorcycles lead to a strong suspection that they can be used in teaching machines to drive autonomously.

This would then explain why these captcha are inserted as often es possible: because Google wants to extort (and profit from) as much unpaid labour as possible.

Unfortunately yes, it's naive to expect honesty in most cases, certainly in any situation where one party has a big financial potential gain. But to stay somewhat on topic il limit it to big IT, you wrote it quite good, the big companies treat us like cattle. Another nice recent example is for example twitter learning grok on all of twitters data via an opt out, not opt in. We are 'content creating cattle' for them mainly. And the only way this changes, is if enough people complaint about it at their governments, or even better when people simply stop using their services.

And even more on topic, Gmail is free for a reason, they read your email, tailor ads based on email content, update your 'commercial profile' based on what you email about and so on. But it is really hard convincing people to stop using good working, and free services. "Oh my information is not important, I dont mind" "Oh its not so bad" "But its free.." is things hear frequently when talking with people.

Data is the new gold.

And if you setup a new mail server, you'll be marked just because you dont have a history of sending email to gmail. They'll make you read and apply what they consider best practices, but then still you have issues getting your mail in the inbox of a user at gmail. Yet they have tons of spammers creating gmail accounts and sending out spam. If you want to setup a mailserver to is _allowed_ to send email to gmail, you'd have to set it up 2 years ago and sending 10 - 50 email gmail addresses to 'learn' the gmail ecosystem your mail server is okay.


My mailserver has SPF, DKIM and DMARC setup and sends about 200 - 300 emails per day to gmail addresses yet, I still get this message sometimes. The only 100% way to fix it, would be to send email via gmail. Because trying to contact somebody at google/gmail about this, is impossible. And using gmail to send my email, is of course a step I will never take. I hate google with a passion.
 
I don't know what You think a "fake proxy" is. But a search is a read-only operation, it does not alter anything. And if google fears they get too many queries, then the could simply limit them, instead of doing prophylactic harassment.
It does, a bot can perform searches using certain keywords and then click on a certain result. Anyway, this is getting offtopic from the mail server

Well, it seems You got my point quite precisely!
This one here, yes, it may be naive to expect honesty - but giving up on that expectation seems even more wrong. That is what did happen in the more recent past: people came up with really great (naive) ideals, like love and peace. And then they got "realistic" (where in fact "corrupt" would be the more appropriate term).

But to stay somewhat on topic il limit it to big IT, you wrote it quite good, the big companies treat us like cattle. Another nice recent example is for example twitter learning grok on all of twitters data via an opt out, not opt in. We are 'content creating cattle' for them mainly.
Even the register does state:

You are the product​

Wait, didn't I hear that earlier? "We have a product on the loose" In that case, when the "products" would start to think for themselves, they had to gas them like the Jews...

And the only way this changes, is if enough people complaint about it at their governments, or even better when people simply stop using their services.
The governments don't help, instead they actually force the people into the arms of the big corps.
From a honesty viewpoint, I would expect a government to make sure in the first place that people have no need to use IT as long as they are not comfortable with it. And then to not allow pseudo advantages for needless use of IT (like you get affordable prices at the grocery only if you allow them to sniff you out).

But in fact the ambitions of governments and big corps are coherent: they both want the people under control (see also my tagline at the bottom ;) ) And IT is the perfect enabler for that.

Let me tell a bit about my background: I didn't learn IT at a college. I learned it at the CCC. When I found out about the Internet, around 1987, it immediately became clear that this would change our entire society in most severe ways. And the only group even thinking that far and considering these implications, at that time, was the CCC. It was a great place for all kinds of futurology, at that time.
At about 1995 the CCC had begun being assimilated by the leftists, and was now rather contemplating about correct gender suffixes and similar SJW concerns. It was no longer a place for futurology, instead they picked themes in the way the government wanted them to do - e.g. "privacy" issues (see above). Like most NGOs they had become lapdogs of the establishment, helping to manipulate the masses in the desired direction.

You are absolutely right: the proper approach would be people complaining to their government, and reminding the officials that they have an obligation to serve the people, not the corps.
And to setup and use independent infrastructure.

But I don't see how that might happen.
What we could probably do, is, build an alliance of independent e-mail operators. As an NGO. And as such an organization, we then could complain about censorship, and maybe even get heard.

Data is the new gold.

And if you setup a new mail server, you'll be marked just because you dont have a history of sending email to gmail. They'll make you read and apply what they consider best practices, but then still you have issues getting your mail in the inbox of a user at gmail. Yet they have tons of spammers creating gmail accounts and sending out spam.
Yepp.
 
Does that help against censorship, suppression, exploit and harassment? If so, how?

See, if I switch to IPv6, I cannot use google at all, because every five minutes they force me to solve a very difficult captcha. Since my IP address is constant, they could learn at the first time that I am a human - which shows that they do it not to find that out, but for the sole purpose of harassment.

My ISP allows me only to receive mail from commercial spam distributors (like google, outlook, etc.), they censor mails from private people. So if somebody wants to mail me, they first have to become customers of these spam distributors where they are forced to watch lots of advertisements.
Can IPv6 change that strategy?

No, it doesn't. Having your own AS won't fix that either. That wasn't the point. In fact, setting up shop for yourself opens you up to a whole lot more potential abuse, suppression and harrassment.

I'm on IPv6 and have been for years now. Google works just fine from any of the /48 prefixes I have available.

Seems like you have a major problem with your ISP. That problem isn't the fault of IPv6 but rather your ISP's apparently strange policies and crummy reputation. Complain to them about those or vote with your wallet and get a connection elsewhere.
 
Now about privacy. It just doesn't exist anymore. It has gone 25 years ago. Back in the 80s/90s we went to the street for privacy, we went to the street against governmental census. It made sense back then, because we did care for our own stuff and didn't want or need the government to interfere.
Yeah, well, I'm not ready to give up yet.
