hi,
ive got a setup problem and im now on my 9th attempt at setting up 
mailman with exim4 :(

im using debian sarge with kernel 2.6.8-2-386 on a firehol box with 
ipmasq etc
(exim4 , mailman & apache2 from apt-get sources)
i ran "update-exim4.conf -o /etc/exim4/exim4.conf" to make my exim4.conf 
file then added the instructions as in 
http://www.exim.org/howto/mailman21.html#roconf

the problem i have is that i can see the web pages ..subsrcibe with test 
accounts...unsubscribe etc, but posts allways come back with this email :-

& logcheck mails me this :-

System Events=-=-=-=-=-=-=Oct 13 15:02:28 irc-mail-firewall Mailman 
mail-wrapper: Group mismatch error. Mailman expected the mail wrapper 
script to be executed as group "daemon", but the system's mail server 
executed the mail script as group "mailman". Try tweaking the mail 
server to run the script as group "daemon", or re-run configure, 
providing the command line option `--with-mail-gid=mailman'.

apart from the group errors i dont suppose im missing something like 
firewall am i??
all help is much appreciated..thanx
