RFC 821 is very old, and does not describe today's world very well. The
revision thereof is in the last stages of the IETF process and may (at
last!) see the light of day this year. However, in the matter of return
codes it hasn't changed much, but personally I am quite happy to use

554 Transaction failed

for errors after DATA. After all, that's what happened!
