My favorite part: “I diffed it against the sendmail.cf in my home directory. It hadn't been altered--it was a sendmail.cf I had written. And I was fairly certain I hadn't enabled the "FAIL_MAIL_OVER_500_MILES" option.”
3ms "connect timeout" would be round-trip, right? So are the calculations at the end of the article incorrect?
