No, it's not always a room filled with wires and glowing blue lights. It's probably not even the size of your furnace. The personal email server used by Hillary Rodham Clinton during her time as secretary of state was probably about the size of your office desktop computer and could have been tucked quietly in a corner somewhere.
She's come a long way since 1997, when Clinton's staff bought the then-first lady a copy of the book "E-Mail for Dummies."
Setting up your own email server is something only the geekiest of tech geeks do because of the serious hassles involved, including spending every waking hour fending off spam. Like brewing your own beer, it's typically done just for fun — a way to challenge your smarts and fill the time. It also appeals to those who fear the government is sniffing around and could compel companies like Google or Yahoo to release customer data.
"It's not trivial to do it, but if you understand how all this works, you can certainly do it yourself," said Carole Fennelly, a New York City-area information security consultant who once operated her own mail server and has set them up for clients.
Setting up your own email server might only cost a few hundred dollars. A common and inexpensive solution might be to take an old computer running Windows; replace the guts of the machine with a free Linux operating system like Ubuntu; and install mail server software that lets you send and receive emails without the help of companies like Google or Yahoo.
Before you get any ideas, Fennelly and other tech experts say there are so many headaches involved with "homebrew" email servers that it's almost never worth it. The cable companies that provide most people their Internet connections don't like them and will often block them because homebrew email servers tend to spew out lots of spam. So you'd have to buy a business-class connection or pay a hosting service. Even then, servers can crash and power outages occur, requiring backup generators and constant maintenance.
"It's a huge, huge headache," said Christopher Soghoian of the American Civil Liberties Union.
As the ACLU's principal technologist and a vocal opponent of government surveillance, Soghoian is exactly the type you'd expect to operate his own email server. But he says he's not comfortable with his technical ability to keep sophisticated hackers out and wonders what risks Clinton was taking. You could probably work around the clock to fend off spam and teenage hackers, he says. But what about the Chinese military?
"What may be a fun activity for a 20-year-old tech whiz is probably a bad idea for the secretary of state," Soghoian said.
So what's the point? In one word, control.
Think of computer servers a bit like post offices. Every time you send an email, that message is stored on a server physically located at a facility owned by Yahoo or Google, for example. That server connects with other networks on the Internet and sends a copy to the intended recipient. At work, your employer probably runs its own email server, storing and sending copies from a computer system maintained by tech support staff.
Either way, every time you write something online, a third party — Yahoo or Google or your employer — has a copy.
