[ILUG] Mailman problems

[Fergal Moran]

I have just set up mailman on a box here.  The installation appeared to
go fine - I can setup new lists and administer them through the web
interface - however the mailing part does not work.  When I try to
subscribe to any of the lists using any of a number of email accounts -
the confirmation email never arrives - and the following mail gets sent
to root at mailman-host

To: root@<mailman-host>
Subject: sendmail-localhost unknown

sh: safe_finger: command not found

safe_finger is installed 
-rwxr-xr-x    1 root     root         6248 Sep 20  2001
/usr/sbin/safe_finger

Symlinking this to somewhere executable by the mailman user does not fix
the problem - however the mail sent to root then becomes
Subject: sendmail-localhost unknown

Sendmail is configured correctly on this machine in that I can send mail
externally from it - and I can receive mail sent to it no problems.  The
only syslog entry that is produced is

Thanks for listening
