MAAWG have considered this a best practice for residential/dynamic IPs since 2005 - http://www.uceprotect.net/downloads/MAAWGPort25English.pdf The FTC and numerous other government agreed the same year - http://www.ftc.gov/bcp/edu/microsites/spam/zombie/letter_english.pdf (The URL in the pdf no longer works - it's not http://www.ftc.gov/bcp/edu/microsites/spam/zombie/) Anyone not yet past the denial stage on this one needs to get themselves a copy of RFC 5068 and start reading.
