Teergrubbing sounds silly to people who know that some spamware uses
illegal SMTP command pipelining. Some spammers send send the entire
client SMTP transaction including the ending TCP FIN before the STMP
server has finished doing the reverse DNS lookup to decide whether to
post its banner. Whether the STMP server delays 10 ms or 10 hours is
of no concern to them.
Ah but you don't understand, 182% of spam is sent through open relays.
So the teergrubbing encourages people to close the open relays - NOT.
The teergrubbing idea sounds to me to be clueless, particularly if let
loose on the general population where we will see folk using it on the
most flimsy of pretexts.
There are people who are aggressively pushing these ideas and we should
address them for that reason alone, even if it is highly unlikely we
would ever endorse them.
I don't think that any of the bulk sender stuff would be caught by
teergrubbing, they must have checks in there to stop them being held up
by slow sites. Heck you have that in most mailing list software.
