Subject: The case of the 500-mile email (was RE: [SAGE] Favorite impossible task?)

Here’s a problem that *sounded* impossible… I almost regret posting the story to a wide audience, because it makes a great tale over drinks at a conference. 🙂 The story is slightly altered in order to protect the guilty, elide over irrelevant and boring details, and generally make the whole thing more entertaining. I was working in a job running the campus email system some years ago when I got a call from the chairman of the statistics department.

“We’re having a problem sending email out of the department.”

“What’s the problem?” I asked.

“We can’t send mail more than 500 miles,” the chairman explained.

I choked on my latte. “Come again?”

“We can’t send mail farther than 500 miles from here,” he repeated. “A little bit more, actually. Call it 520 miles. But no farther.”

    This deserves to be a classic.

    It took me a while to appreciate just how subtle networking problems (and the solutions to them) at OSI Layer 2 can get – this subtle interaction between Layer 1 and sendmail to produce a weird problem, not gives the lie to the only semi-joking assertion that “any problem in computing can be solved by adding another abstraction layer”.
