Re: [GTALUG] Aggressive and Underhanded?
by D. Hugh Redelmeier 13 Jun '18

| From: ac via talk <talk(a)gtalug.org> | I was wondering whether I am the only one noticing that Google and | Microsoft has become increasingly aggressive and underhanded in their | email operations? No, I haven't. But then there is no reason why I would. I run my own mail server but only for my family. Can you be more explicit about what I would notice and what they are doing that is wrong? Note: I'm not challenging the correctness of what you are claiming, I'm just trying to understand it. Remember I, and probably most other list, members don't have your level of knowledge about this. I understand that Google and Microsoft are very very dominant in email. This is so very different from when I started -- every little group ran their own server. I guess that the main driver is SPAM. The above-board reason is that SPAM detection is a balance between hard and imperfect. I'm willing to live with imperfect but many folks are not. My amateur act spam handling: SPAM Assassin (uncustomized) + some custom procmail rules + each user gets do delete what comes through. I understand the G&M do much better SPAM detection. To the extent that they've forced all mailing lists (including this one) to change in an unpleasant way. Or maybe that was just Yahoo. I think that you are saying that G&M are now pushing the burden onto other providers, but I don't understand how. Is it a matter of forwarding or of originating? I thought that very little forwarding (except internally) happens these days. I kind of think you only need to judge the last hop. Your complaints about IPv6 aren't clear. Is that about internal forwarding? Is the problem that those internal nodes don't accrue "reputation"? Why would IPv6 be worse than IPv4? (I've had internal IPv4 forwarding at times. Those IP addresses happened to be routable addresses, with forward and reverse DNS entries, but that was kind of accidental.) (Aside: although not currently the case, I used to and intend to use forwarding to provide for secondary mail servers. I.e. sometimes my power goes down or my internet connectivity goes down and I want my mail to go to a secondary server and then flow to my main one when it comes back. I haven't put the time in to figure out how I can handle inbound DKIM correctly in that case.) | I noticed the trend a few years ago already and have been watching for | new patterns and collecting millions upon millions of spam emails | | Microsoft and Google is dominating email relay and their market share | in the geo areas where they dominate, has steadily increased each year. So it seems to be relaying. But I thought that relaying is broken by DKIM so it is no longer done. In other words, DKIM is kind of end-to-end with no provision for relaying. There ought to be support for trusted relaying. What I mean is: a last hop that you trust to not lie about what it is forwarding so you can look at the headers it passed to you with as much trust as normal last-hop headers. Without this, your mail system can only really look at the last hop. Is there any formal mechanism for trusted relaying? | Both monopolies are now using more and more complex email headers. I'm guessing that you are trusting the last hop, if it is Google or Microsoft, and want to be able to look through their header transformations to see what they actually got so you can filter on that. So your complaint is that they are making it more and more difficult to look through those header transformations. Am I correct? I guess that there is another problem. If each trusted forwarder has to be handled differently, there is a limit on how many can be trusted. Then Google and Microsoft probably make the cut and our servers probably don't. | The result of this new aggressive push is declining quality of email | service for smaller providers - as ham is marked as spam more | frequently. | | They (Microsoft and Google) are using their sheer size to bully out | more market share and if the trend continues there will be no more | 'independent' email providers in the near future as more and more | providers are forced to run their email services through one of the two | monopolies. So are you saying that they've "accidentally" made it harder for providers to "look though" their forwarding when trying to filter? | Anyone else noticed the more aggressive system designs, more aggressive | non responsiveness to abuse complaints and other non ethical behaviors? | And, is there anything that general society can even do? "Aggressive" seems like a leap. How about "designed to not interoperate well"? | If there are only two email providers in the future, how long will it | take before there is just one? An oligopoly is of the same nature as a monopoly. So what we have is already a monopoly regime. But reducing the number of players would almost certainly make things worse. [RANT] I truly believe that monopolies are the scourge of our era. Political "free marketeers" don't seem to understand that a free market requires constraints on monopolies. Look at the Republican Party in the US. It seems to be willful blindness because they don't even get it when it is explained to them (eg. FCC and Network Neutrality) - there are only a few ways of dealing with natural monopolies (often caused by the network effect). They should be used in combination. + public ownership (i.e. government ownership or co-ops). Not intrinsically better than private monopolies, but with care can operate with a better mandate + regulation + forcing the monopoly to operate in the narrowest possible domain (i.e. without doing anything other than the function subject to the natural monopoly). A good example would be separating electricity generation from transmission (a natural monopoly) Monopolies generate a lot of "rent". This rent is used to corrupt governments in various ways (many tacit and unrecognized by the participants). This seems to be too hard for the electorate to understand so nothing gets done. It looks as if the next area of big change is going to be with autonomous vehicles. There seems to be no planning done with the public interest in mind. What happens is probably going to be determined by corporate competition. The outcomes are likely to be determined by the wrong objective function. [END RANT]

I guess it depends on what you consider "email relay" For LPI's outgoing mail. we use mailman and OpenEMM for anything other than one-to-a-few personal communications. For the SMTP relay we use Sparkpost. This is a combination of self-hosted open source solutions combined with a trusted cloud service owned by neither G nor M nor A. - Evan On Tue, 12 Jun 2018 at 02:05, ac via talk <talk(a)gtalug.org> wrote: > Hey Everyone, > > I was wondering whether I am the only one noticing that Google and > Microsoft has become increasingly aggressive and underhanded in their > email operations? > > I noticed the trend a few years ago already and have been watching for > new patterns and collecting millions upon millions of spam emails > > Microsoft and Google is dominating email relay and their market share > in the geo areas where they dominate, has steadily increased each year. > > recently there has been more changes > > Both monopolies are now using more and more complex email headers. > > Both Microsoft and Google have become more aggressive, more dominating > and seemingly less ethical in their behaviors. > > Google has apparently moved their back end mail servers to private ipv6 > ranges and are pumping emails out, spam and ham, through ipv4.
