[Mailman-Users] problem with confirming subscriptions

[Todd Shrider]

This is the error that i get when a user tries to subscribe to the list i
have created:

   ----- The following addresses had permanent fatal errors -----
"|/usr/people/mailman/mail/wrapper mailcmd 3dstudiomax"
    (expanded from: <3dstudiomax-request at einsteinium.cin.kascope.com>)
   ----- Transcript of session follows ----- 554
"|/usr/people/mailman/mail/wrapper mailcmd 3dstudiomax"... unknown mailer
error 2


Any ideas?
