Tutorial: Email server for a small company – including IMAP for mobiles, SPF and DKIM

For best article visual quality, open Tutorial: Email server for a small company – including IMAP for mobiles, SPF and DKIM directly at NetworkGeekStuff.

email_iconA few months back my wife started a small business. Of course I was the one to build the “IT stuff” here that included a website, some reservation system on it for customers (php programming here), local network in the office and customer area and other things. Most of that was all pretty common tasks for me with the exception of one, building an email system for a company emails. So I built it and since it was new and interesting experience for me, I will share here a quick tutorial (or better call this a cookbook?) to replicate the very minimum system.

Now also let me state here that I really missed somehow in my life running a real email system so far. And it was a little challenge to setup it properly for the first time.

Survey claims New York startup scene is more innovative

A new survey is attempting to kick-start a rivalry between New York and Silicon Valley, claiming tomorrow’s innovative tech companies will pick east over west to set up shop.Out of 318 executives surveyed, more picked New York over Silicon Valley as the superior place to start a business, due to factors such as growing interest from venture capitalists, support from city and state government, and the considerable talent pool from Wall Street firms and Fortune 500 companies in the city.The survey was conducted by a New York-based data analysis company, 1010data, so we should probably take the findings with a grain of salt.

Open Choices In Networking

neo-architect

I had an interesting time at the spring meeting of the Open Networking User Group (@ONUG_) this past week. There were lots of discussions about networking, DevOps, and other assorted topics. One that caught me by surprise was some of the talk around openness. These tweets from Lisa Caywood (@RealLisaC) were especially telling:

After some discussion with other attendees, I think I’ve figured it out. People don’t want an open network. They want choice.

Traditional networking marries software and hardware together. You want a Cisco switch? It runs IOS or NX-OS. Running Juniper? You can have any flavor of OS you want…as long as it’s Junos. That has been the accepted order of things for decades. Flexibility is traded for predictability. Traditional networking vendors give you many of the tools you need. If you need something different, you have to find the right mix of platform and software to Continue reading

Six China residents charged with stealing US mobile phone technology

Six residents of China face economic espionage and theft of trade secret charges for allegedly funneling radio frequency technologies used in mobile devices from U.S. companies to a university controlled by the Chinese government.The defendants facing charges in the U.S. are connected to Tianjin University in China. The U.S. Department of Justice released a 32-count indictment on Tuesday, three days after Tianjin University Professor Hao Zhang was arrested at the Los Angeles airport while trying to enter the U.S. from China. The five other defendants remain at large.The six are charged with stealing thin-film bulk acoustic resonator (FBAR) technology used in mobile phones from two U.S. companies, according to a DOJ press release. FBAR technology filters incoming and outgoing wireless signals so that a mobile phone only receives and transmits the specific communications intended by the user. In addition to consumer applications, FBAR is used in several military and communications technologies.To read this article in full or to leave a comment, please click here

I wrote an entire series on this same topic a while back on Packet Pushers, if you want commentary to go with the slides —

Part 1: Basic Operation
Part 2: Protections Offered
Part 3: Replays, Timers, and Performance
Part 4: Signatures and Performance
