Maildrop permission problems

[Sam Varghese <sam@gnubies.com>]

I have been trying to get a script to run on
a server which runs potato. I've checked the
script using perl -cw <script_name> and it checks
out okay.

The script has been put in /usr/local/bin and
to test it out I have created a user called
testuser. In this user's home directory I have 
made a forward file containing one line:

"|/usr/bin/maildrop"

This file is set to 0644.

I have made a file called .mailfilter in the home
directory with the following:

DEMIMEFILTER="/usr/local/bin/demime -"

if (/^Content-Type:.*html/   ||    \
    /^Content-Type:.*rtf/    ||    \
    /^Content-Type:.*multipart/)
{
    xfilter $DEMIMEFILTER
}

again, the file is set to 0644.

When I send mail to testuser from one of the workstations
on the LAN, the mail bounces with the following error message:

------ |/usr/bin/maildrop ------

usr/bin/maildrop: Unable to create a dot-lock.

------ This is a copy of the message, including all the headers. ---

The maildrop version is 0.75-2.1. The permissions on the
maildrop files are as under:

 -rwxr-xr-x    1 root     root        23576 Aug 12  2000 dotlock
 -rwxr-xr-x    1 root     root         4312 Aug 12  2000 maildirmake
 -rwxr-sr-x    1 root     mail       139448 Aug 12  2000 maildrop
 -rwxr-xr-x    1 root     root        36376 Aug 12  2000 reformail
 -rwxr-xr-x    1 root     root        31228 Aug 12  2000 reformime

What am I doing wrong?
