details of the *-subscribe function

Hi people,	(first post to this list)

I have a few email lists and none of them seem to honor the address:

<list-name>[email protected]

And I can't figure out why.  My first question is how do I go about
diagnosing this problem in an efficient manner.  Currently I send an
email and wait a week for qmail to give up.  The more specific question
is what is wrong?  I get this back:

        Hi. This is the qmail-send program at host.domain.tld.
        I'm afraid I wasn't able to deliver your message to the following addresses.
        This is a permanent error; I've given up. Sorry it didn't work out.
        
        <list-name>[email protected]
        /bin/sh: 060: command not found
        I'm not going to try again; this message has been in the queue too long.
        
        --- Below this line is a copy of the message.
        ...

I do not have a shell in /bin/sh but I have a shell in /bin/bash and a
symbolic pointer from /bin/sh -> /bin/bash so it should work shouldn't
it?  Although it looks like bash is looking for the command "060" and
that makes even less sense.  How can I check for this?

Is the command that is failing qmail-local?  

How do I trace a message through the system?  I really don't need
baby-sitting, just a pointer to a good tutorial please.  

Should there be a .qmail-<list-name>-subscribe file?

Thanks in advance,
Tres
