   I have written and installed a remailer pinging script which
collects detailed information about remailer features and reliability.

   To use it, just finger remailer-list at

   There is also a Web version of the same information, at:

   Please let me know about any other remailers which I missed. I've
only included remailers which can mail to arbitrary addresses, so I
already know chop and twwells are missing.

   This information is used by premail, a remailer chaining and PGP
encrypting client for outgoing mail, which is available at:

   For the PGP public keys of the remailers, as well as some help on
how to use them, finger at

This is the current info:

                                 REMAILER LIST

   This is an automatically generated listing of remailers. The first
   part of the listing shows the remailers along with configuration
   options and special features for each of the remailers. The second
   part shows the 12-day history, and average latency and uptime for each
   remailer. You can also get this list by fingering
   remailer-list at

$remailer{"chaos"} = "<remailer at> cpunk hash ksub";
$remailer{"vox"} = "<remail at> cpunk oldpgp. post";
$remailer{"avox"} = "<anon at> cpunk oldpgp post";
$remailer{"extropia"} = "<remail at> cpunk pgp special";

$remailer{"alumni"} = "<hal at> cpunk pgp hash";
$remailer{"bsu-cs"} = "<nowhere at> cpunk hash ksub";

$remailer{"wien"} = "<remailer at> cpunk pgp hash nsub";
$remailer{"c2"} = "<remail at> eric pgp hash";
$remailer{"soda"} = "<remailer at> eric pgp. post";
$remailer{"penet"} = "<anon at> penet post";
$remailer{"ideath"} = "<remailer at> cpunk hash ksub";
$remailer{"usura"} = "<usura at> cpunk pgp. hash latent cut post";
$remailer{"leri"} = "<remail at> cpunk pgp hash";
$remailer{"desert"} = "<remail at> cpunk pgp. post";
$remailer{"underdog"} = "<lmccarth at> cpunk pgp hash latent cut post";
$remailer{"nately"} = "<remailer at> cpunk pgp hash latent cut";
$remailer{"efrias"} = "<efrias at> cpunk pgp hash";
catalyst at is _not_ a remailer.

   Options and features

          A major class of remailers. Supports Request-Remailing-To:

          A variant of the cpunk style. Uses Anon-Send-To: instead.

          The third class of remailers (at least for right now). Uses
          X-Anon-To: in the header.

          Remailer supports encryption with PGP. A period after the
          keyword means that the short name, rather than the full email
          address, should be used as the encryption key ID.

          Remailer does not like messages encoded with MIT PGP 2.6. Other
          versions of PGP, including 2.3a and 2.6ui, work fine.

          Supports ## pasting, so anything can be put into the headers of
          outgoing messages.

          Remailer always kills subject header, even in non-pgp mode.

          Remailer always preserves subject header, even in pgp mode.

          Supports Matt Ghio's Latent-Time: option.

          Supports Matt Ghio's Cutmarks: option.

          Post to Usenet using Post-To: or Anon-Post-To: header.
          Accepts only pgp encrypted messages.

   History key

   If you've got a Web page, please feel free to include a link to
this page. If you think your Web page is relevant to the subject of
remailers, let me know and I'll link it in.

   Comments and suggestions welcome!

   Note to remailer operators: this script generates hourly ping
messages. If you don't want that, let me know and I will take your
mailer off the list, or increase the interval between pings.
