Return to sender (after 500 miles)
We can't send mail farther than 500 miles (2002)
Legendary email glitch returns: nostalgia, memes, and “I can’t believe this” vibes
TLDR: A famous 2002 story about emails failing beyond 500 miles resurfaced, sparking nostalgia, memes, and debate over whether such bizarre glitches could still happen today. The community calls it a timeless classic while arguing old ghosts still haunt modern tech—making this legend feel oddly relevant now.
The internet just dusted off a beloved spooky tech campfire story: the 2002 tale of the campus that couldn’t send email more than ~500 miles. In the story, an admin tests cities like a detective with a map—New York works, Boston fails—until a cryptic clue appears: an old Sun server banner. Cue the goosebumps.
But the real show is the comments. Hacker News veterans chant “classic” like it’s Rocky Horror, with throwback links to giant past threads from 2023 and 2020. One line has become pure meme fuel: the imaginary switch to flip, “FAIL_MAIL_OVER_500_MILES.” Users are still quoting it like it’s Seinfeld.
Nostalgia dukes it out with practicality: Old‑guard sysadmins swap war stories about ancient email software and weird network gremlins, while younger devs gasp that anything could break by “distance.” The drama spikes when people ask if this could still happen—and someone drops a fresh thread, “Can an email go 500 miles in 2025?”. Half the crowd says modern tools would catch it; the other half insists today’s corporate firewalls could absolutely make the same spooky magic happen.
Meanwhile, the joke machine never stops: quips about putting email on a 500‑mile diet, mapping the “blast radius” with geostatisticians, and needing airmail for anything past 520 miles. Verdict from the community court: this isn’t just a bug story—it’s a timeless vibe, a meme, and a reminder that tech’s weirdest failures make the best legends.
Key Points
- •A statistics department reported outbound email failing beyond roughly 500–520 miles from their location.
- •Harris verified the issue with tests: nearby cities worked; farther destinations (e.g., Memphis, Boston, Detroit, Providence) failed.
- •A geostatistician mapped a radius of successful email delivery with sporadic exceptions inside the radius.
- •The server’s sendmail.cf matched Harris’s known configuration, suggesting no obvious config change caused the problem.
- •Connecting to SMTP revealed a SunOS sendmail banner; at that time Sun shipped Sendmail 5 despite Sendmail 8 being mature.
