RFC 0000: The Null Exchange

mxnull.com Visit website

Editorial interest 85/100 Selection signal · not a rating of the site

A satirical RFC-style document describes a mail exchanger that accepts messages and sends nothing back.

Landing page captured for the 2026-09-26 issue.

For: Readers of internet-protocol jokes and deadpan technical satire
Worth noticing: Its retention clause offers 7, 14, 30 days—or the heat death of the universe, whichever the recipient selects.

Field notes

The page uses linked RFC sections and familiar standards language, including BCP 14, as the frame for its joke. Its requirements, FAQ, and author address keep the deadpan format going: the author is listed as “Nowhere in particular,” with an email address of “yes.” The extracted page establishes the document’s contents, but not whether any mail-server behavior described in it is implemented.
