We won't have the entire message to make a proper
assessment. Reputation-checking only works with known
senders. Recipients expect zero spam and instant delivery of their emails. :-)
TBR assumes a direct path to retrieve the message. That's not always
the case for Internet mail. There may also be HTTP proxies in
between which may affect message retrieval.
The main problem these days is not storage. Email may be seen as
fire and forget. I gather that your draft attempts to reverse
that. That may not have that much impact on "questionable" senders
as they have unlimited resources and a propensity to overcome the hurdles.
