My bet is:
550, "5.7.1", Our system has detected that this message is likely
unsolicited mail. To reduce the amount of spam sent to Gmail, this
message has been blocked. For more information, visit Why has Gmail
blocked my messages?
Google / Gmail is been ratcheting up the anti-spam measures as of the
last 3+ months, including /requiring/ headers that RFCs may not actually
require; e.g. SHOULD vs MUST.
There has been a lot of noise about this moving target of a change on
Google / Gmail's part, at least in many circles that I travel.
