REMAIL: remailer tech

Thanks for the note, L.Detweiler!

Let's see, I added a bunch of files to the gopher site, and I'll do
more maintenance next weekend.

I sent out remailing requests, and got responses from these remailers:

Remailed-By: Remailer <catalyst-remailer at netcom.com>
X-Remailed-By: Anonymous <remailer-admin at chaos.bsu.edu>
X-Remailed-By: Anonymous <nowhere at bsu-cs.bsu.edu>

                                    insufficent funds message

The following errors were received:

"|/u50/sameer/.myfilt"  (unrecoverable error)
    (expanded from: <sameer at netcom.com>)

550 <remail at tamaix.tamu.edu>... User unknown

So that's hearing from 18 out of 21, and maybe some more will drift in
shortly :-)  I'll test again in a while.

Yes, this is what the remailer at menudo does, all incoming mail is
just filed away, and then remailed at midnight.  I beleive I changed
the mailout script to pause for 5 or 10 seconds in between mailing.
Hopefully this will guard against massive onslaught attacks.
