$remailer{"sinkhole"} = "<sinkhole@lousyroad.com> mix middle remix inflt50 rhop5 reord klen1024 testing";

Here is the Mixmaster key:
Use only one mixmaster key per remailer unless your client can handle multiple.
A key length of '258' in this file means 1024-bit RSA as y=(x-2)*4.
1024-bits offers inferior security to the larger keys that require at least version 3.0.2.
