Problem with "owner"

[Pierre-Etienne Mélet <melet_pierre_etienne@xxxxxxxx>]

Hi all,

  before compiling my own iptables (I'm working with iptables 1.2.7 rpm 
given with Mandrake 9.1), i'd like to be sure i'm not making a mistake:

My purpose is to allow thunderbird only to access internet through pop3:

$IPTABLES -A INPUT -i $EXTERNAL_IF -p tcp --sport pop3 \
       -m state --state ESTABLISHED,RELATED -j ACCEPT

$IPTABLES -A OUTPUT -o $EXTERNAL_IF -p tcp --dport pop3 \
       -m owner --cmd-owner 'thunderbird-bin' \
       -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT


Unfortunately, "thunderbird-bin" is unable to pass the firewall.

What am i doing wrong ?

Best regards.
