Has anybody claimed that post-processing within the SMTP-server is
better than postprocessing done elsewhere? The issue was
in-line-processing vs post-processing.

No information you can collect from the SMTP-session or elsewhere can
ever compete with the accuracy in notification gained if you reject the
message in-line and leave the responsibility for sender-notification
with the sending MTA.
