There may not be a stoplight in your hometown, but there’s a United States Postal Service® (USPS) post office. Post offices become the hub of many communities because they are reliable. It’s comforting that “neither snow nor rain nor heat nor gloom of night” will prevent letter carriers from delivering the mail. Neither Snow Nor Rain.

The SMTP protocol is responsible for carrying some of users' most intimate communication, but like other Internet protocols, authentication and confidentiality were added only as an afterthought. In this work, we present the first report on global adoption rates of SMTP security extensions, including: STARTTLS, SPF, DKIM, and DMARC. We present data from two perspectives: SMTP server configurations for the Alexa Top Million domains, and over a year of SMTP connections to and from Gmail. We find that the top mail providers (e.g., Gmail, Yahoo, and Outlook) all proactively encrypt and authenticate messages. However, these best practices have yet to reach widespread adoption in a long tail of over 700,000 SMTP servers, of which only 35% successfully configure encryption, and 1.1% specify a DMARC authentication policy. This security patchwork---paired with SMTP policies that favor failing open to allow gradual deployment---exposes users to attackers who downgrade TLS connections in favor of cleartext and who falsify MX records to reroute messages. We present evidence of such attacks in the wild, highlighting seven countries where more than 20% of inbound Gmail messages arrive in cleartext due to network attackers.

Neither Snow Nor Rain Book

“[The] book makes you care what happens to its main protagonist, the U.S. Postal Service itself. And, as such, it leaves you at the end in suspense.” —USA Today Founded by Benjamin Franklin, the United States Postal Service was the information network that bound far-flung Americans together, and yet, it is slowly vanishing. Critics say it is slow and archaic. Mail volume is down. The workforce is shrinking. Post offices are closing. In Neither Snow Nor Rain, journalist Devin Leonard tackles the fascinating, centuries-long history of the USPS, from the first letter carriers through Franklin’s days, when postmasters worked out of their homes and post roads cut new paths through the wilderness. Under Andrew Jackson, the post office was molded into a vast patronage machine, and by the 1870s, over seventy percent of federal employees were postal workers. As the country boomed, USPS aggressively developed new technology, from mobile post offices on railroads and airmail service to mechanical sorting machines and optical character readers. Neither Snow Nor Rain is a rich, multifaceted history, full of remarkable characters, from the stamp-collecting FDR, to the revolutionaries who challenged USPS’s monopoly on mail, to the renegade union members who brought the system—and the country—to a halt in the 1970s. “Delectably readable . . . Leonard’s account offers surprises on almost every other page . . . [and] delivers both the triumphs and travails with clarity, wit and heart.” —Chicago Tribune
