Hashcash Advice Requested

I would be grateful for advice about the best way to
configure the hashcash for Reliable.
At present, if an exit message does not contain a
valid hashcash token, it is set to hand the message
to a randomly chosen remailer rather than send it
to the m2n gateways.
I would prefer to drop the message, since this would
keep floods from being passed on to other remailers,
but I seem to recall there were objections to that
when Panta (I think) wanted to do it that way.
The only objection I can think of is that somebody
who lets QS or JBN choose his exit remailer and
doesn't use hashcash, may have eelbash chosen and
lose his message.
If I have that right, it seems like an insuperable
ojbection, but maybe it isn't, or maybe I don't
have it right, and hope you experts can advise me.

There is no capstring within Type-I or Type-II to say that a remailer
requires Hashcash. Users who randomly select Eelbash as an Exit will
lose their postings. We've been through this once before when you asked
all the ping operators to de-list you. A week later you asked them
to put you back.
These sort of changes are particularly nasty as stats report remailer
reliability on email delivery, not news. You can drop 100% of usenet
postings and still users will randomly select you.

I don't imagine you mean the use of hashcash in general, but only if
it is
set up to drop non-hashcash exit posts altogether.

Thanks. I don't want to do anything to impede the flow of legitimate
mail
and news posts, so I guess I better stick with simply forwarding
non-hashcash exit posts to a randomly chosen remailer the way Panta
does.
I guess the effect will be to lengthen the chain, which shouldn't be
a
problem, given the high reliablity these days, and to remove any
custom
- From header the user had in the header.
That seems piddling compared to blocking the spam and discouraging
the
predatory individuals who tend to batten on last-hop remailers.

There are various issues with Hashcash in general, but the only one
specific to remailers is the lack of hashcash capstring. As a general
rule, if a function doesn't have a capstring then don't offer it.

No real problem, just that you (and users) need to remember that you are
not lengthening the chain by one, but rather creating a new chain of one
remailer. The original message is fully decrypted at Eelbash and then
resent to another remailer which you select.

Couldn't echolot be modified to also send pings to a testing newsgroup?
