With Posteo, the user sets up their account anonymously and also pays anonymously. Posteo even implements two-factor authentication 2FA, a security feature anonymously.
Berlin company Posteo has this Monday presumably become the first email provider in the world to implement modern DANE technology, which ensures encrypted transport of emails.
Posteo is not merely a commercial project. Its absolute commitment to privacy shows that communications providers can also think and act politically.
Posteo works with all current encryption methods. Above all else, it collects as little data as possible from its customers. There are many email providers, but Posteo stands out from the crowd.
The small Berlin company not only operates with optimum security and privacy, but also has an especially sustainable philosophy. Certificate pinning is a relatively new standard, which works towards restoring trust in encryption on the web.
Posteo is now the first larger German provider to test this concept in practice. As an alternative to the main email providers, WDR internet expert Jörg Schieb recommends an account with the German service "Posteo", which is completely ad-free and highly values the privacy of data and personal information.
To establish trust in the company's integrity, Posteo in May became the first German email provider to publish a transparency report on requests from authorities.
The former Greenpeace activists at Posteo comply with applicable laws with more discipline than the investigative authorities prefer to.
Posteo is one of the most unusual German start-ups: The email provider declines to use advertising and wants to collect as little data from its users as possible.
Posteo, on the other hand, impressed. The small email provider was the only German email service to offer encryption with Forward Secrecy for all email protocols.
Berlin-based provider Posteo offers a lot of comfort, great features and a high security standard, for little money. Posteo operates with green energy, its own capital and permanent employee contracts in order to offer secure email accounts.
The Berlin company is up with the times. Crypto mail storage provides Posteo customers with personalised encryption of their entire email data at the click of a button.
Well before the NSA scandal, a small team in Berlin had already thought about secure — and above all else, truly private — email communication, founding the email service Posteo in Most reports and articles concentrate almost exclusively on Posteo's stance on privacy and data security.
The plan to establish an alternative email provider originally arose out of an ecological motivation. The transparency report presented today by Posteo levels fierce criticism at the practice of requests from authorities.
One distinctive feature is that with Posteo, address books and calendars added online can be encrypted by the user.
An account with 2 GB storage space costs 1 EUR per month — for that fee it is ad-free, the servers are run using green energy from Greenpeace Energy, and support by email is free of charge.
One special feature is that Posteo allows its users to save their complete email, address book and calendar data in encrypted stores. The account costs 1 EUR per month, for which the customer receives 2 GB storage space and the assurance of being with a company that uses green energy and an account with the GLS Bank.
This means we can hire people with ease, that already know the technology that we use. Then what happens if we use a super fast custom framework and then the "hacker" that wrote it leaves the company?
Who will maintain his code? And then your suggestion about moving to another framework sounds nice in theory, but do you know how many months of development could take to port the site code to another framework?
We also have to pay for our developers salaries which most of the time is more expensive than one of this blade servers.
So as I said in an answer before, companies do business decisions, not just choose this or that framework because is fast.
So please, don't blame the number of servers on symfony, because while yes is heavier than plain PHP code, is not the reason why we use so many.
If not then why do you use PHP? Alvaro, i'm in no way questioning your infrastructure since you know it better than anybody else here, especially some of those 'armchair system architects.
Thanks for you insights. I agree with you. Is not that you go and throw money at hardware, there should be an equilibrium.
We also try to improve our code when we can, i. We are working on a lightweight solution for SQL queries, which according to our benchmarks will reduce quite a lot of load from the site since we can remove the ORM that we use, which is quite heavy.
Our site is evolving and we are learning from our mistakes as everyone should do. Regarding the load average statement, I said that because for some commenters it look like we have 28 completely overloaded machines.
Besides that we have those machines in place because we are planning for future growth, by future we mean imminent if everything goes as planned.
About APC vs. We have to ponder more that. Sometime we discuss the same as what you just said. I have no experience related to that to give an opinion.
Also APC cache is not shared, we have to ponder if that is a problem too. We do cache several computations into APC too.
Thanks for a great article! I have one question about your nginx and memcached. You wrote that many requests doesn't even hit PHP, because Nginx gets the cached content from memcached - can you describe it a little bit more?
Do you cache HTML pages? Erlyvideo is developed very rapidly. Several months ago you could see previous generation of it, that couldn't do anything.
So, if you are interested, better to communicate via email. Alvaro, I think you should try Erlyvideo - it's wrotten in Erlang, and it develops very fast.
What I found most interesting is how they manage to sucessfully blend a little of the old with a little of the new. No, they didn't manage to successfully blend old and new.
It's nearly never really fast, also every few weeks extra slow for at least a few hours, often for weeks. The current slow-period is on since about 6 weeks, and still no end in sight.

Toolbox Nginx All our site is served via Nginx. Memcached We use Memcached heavily. Graphite We use Graphite to collect real time information and statistics from the website.
Red5 Our site also serves video to the users. Tsung Tsung is a distributed benchmarking tool written in Erlang.
Lessons Learned While Buzz Oriented Development is cool, look for tools with an important community behind them. Documentation and a good community are invaluable when there are problems to solve, or when you need to incorporate people to your team.
CouchDB and RabbitMQ also have good support from their developers, with active mailing list where questions are answered in time.
We learned a lot from symfony. Where it could be tweaked and what could be improved. Another example is Nginx, several problems that we had were already solved by the Nginx community, like what we explained about the image storage cache.
Extend the tools. If they are working well there's no need to introduce new software into the current stack.
We have written several Nginx modules that have even been tested by the Nginx community. In this way you contribute back. D on't be conservative with what doesn't matter.
Graphite seemed to be a cool tool for running in production, but there wasn't so many reports about it. We just had to give it a try.
If it hadn't worked, we could have just disabled it. Nobody will cry if we couldn't get a nice graph of Unix Load in our systems.
Today even our Product Managers love it. Learn to interpret those metrics. Create tools that let you react to problems as fast as possible. If you have to rollback a deployment, you don't want to spend more than a second doing that.
Create tools that let you profile the site live. In the lab most tests give optimistic information, but then fail to cope with production load.
The Future Build a new more scalable Message System, since the current version is quite old and wasn't designed for such an amount of messages.
Move more and more processing tasks to the queue system. Add more Erlang applications to our system. We are looking for a replacement for Red5, probably the Oneteam Media Server which is written in Erlang.
While at the moment we are using open source Erlang products, we may start writing our own applications with the language because now we have experience with it.
Improve our log visualization tools. Reader Comments 21 Let's do the math. I know of sites that serve this number of requests with PHP using servers.
This means that we will have concurrent updates to the users table, to store the user last login time No that does not mean you have concurrent updates.
