[Mailman-Users] Unknown Mailer Error 2

[Chris Wilhoit]

After replying to the "confirmation of subscription" I receive returned
mail with:

----- The following addresses had permanent fatal errors -----
"|/home/mailman/mail/wrapper mailcmd test"
        (reason: 2)
        (expanded from: <test-request at penguin.kelin.net>)

Thanks
Chris
