[cobalt-security] email list error - help needed pls

["Mez" <mez@xxxxxxx>]

I have had an email list setup for my customers on my Cobalt Raq3 for some
time now, has been working fine no problems.
But today i send an email to the list and the email was returned with the
following error:

----- The following addresses had permanent fatal errors -----
"|/usr/local/majordomo/wrapper -v site4 -f list.wherever.co.uk  resend -l cm
cm_site4-list"
    (expanded from: <cm@xxxxxxxxxxxxxxxxx>)

   ----- Transcript of session follows -----
/usr/adm/sm.bin/wrapper: error getpwnam failed errno
2/usr/adm/sm.bin/wrapper: error: Not running with proper UID and GID.
    Make certain that wrapper is installed setuid, and if so,
    recompile with POSIX flags.
554 "|/usr/local/majordomo/wrapper -v site4 -f list.wherever.co.uk
 resend -l cm cm_site4-list"... Internal error

Anyone have any ideas what has caused this problems and how i resolve?

Thanks in advanced
