mailman on ubuntu server 10.04

[Eric Alan Solo]

Hello

I've been trying to setup mailman on my server but it's just not working.
I've tried so many thing's i've searched that I have become totally confused.
This is what happened...

At first, I was getting the error:
--------------------------------------
Mailman CGI error!!!
The Mailman CGI wrapper encountered a fatal error. This entry is being
stored in your syslog:
Group mismatch error.  Mailman expected the CGI
wrapper script to be executed as group "www.-data", but
the system's web server executed the CGI script as
group "ftpgroup".  Try tweaking the web server to run the
script as group "www-data", or re-run configure,
providing the command line option `--with-cgi-gid=ftpgroup'.
-------------------------------------

ftpgroup is the user group that my apache runs as.
Then one of the hundreds of things I tried ended up getting it to
work, and I added some lists.

But the mails were not being sent. So i tried a few hundred more
things and now I'm getting this error:
-------------------------------------
Forbidden

You don't have permission to access /cgi-bin/mailman/ on this server.
Apache/2.2.14 (Ubuntu) Server at intertron.net Port 80
-------------------------------------

I've tried messing with chown and chmod for hours but nothing helps.
Is there anyone who can help me through this?

Cheers,
Eric
