Reliable's remailer-conf includes the sections
  SUPPORTED CPUNK (TYPE I) REMAILERS
  SUPPORTED MIXMASTER (TYPE II) REMAILERS
That is quite convenient to check remailers holding incorrect keys
 or detect those referencing unknown (probably dead) remailers.
Because latest versions of Mixmaster remailer-server now include the feature,
 I wrote a little proggy to analyse those data

My Thesaurus collects, stores and analyses remailer-xxx replies
  http://frogadmin.yi.org/Thesaurus/

Here comes some result,
The remailer-conf replies are checked
 against *Arbitrary_Ping_Leaders*' keyrings: PGP (RSA+DH/DSS) and MIX (LIS/MIX) 

'N/A'       means that the remailer-server software does not supply the information
'INCORRECT' *should* trigger some action from the remop holding a wrong key
              there is *serious* risk of mail loss
'UNKNOWN'   may mean a test remailer, a nymserver or a dead corpse
              some cleanup is suggested

Some remailers are in some 'twilight zone' and will show as 'UNKNOWN'
 because *both* Arbitrary_Ping_Leaders decided *not* to reference them:
      notatla   test
      nutshell  test
      listman   unannounced
      starwars  unannounced 
      narnia    supposedly dead (quotas -> 'mailbox full')
