I have configured squid at RedHat Linux 5.4 and all my Windows networks use 192.168.5.100 and port 3128 as proxy for accessing Internet.

But while sending and receiving emails at Microsoft outlook email client I am not connected to Internet

iptables -t nat -A POSTROUTING -p TCP --dport 25 -j MASQUERADE
iptables -t nat -A POSTROUTING -p TCP --dport 110 -j MASQUERADE`iptables -P INPUT DROP  
iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A INPUT -i 192.168.5.100 -p tcp -m tcp --dport 22 -j ACCCEPT
iptables -A INPUT -i 192.168.5.100 -p tcp -m tcp --dport 3128 -j ACCCEPT
iptables -A INPUT -i 192.168.5.100 -p tcp -m tcp --dport 25 -j ACCCEPT
iptables -A INPUT -i 192.168.5.100 -p tcp -m tcp --dport 110 -j ACCCEPT
iptables -A INPUT -i lo -j ACCEPT
iptables -t nat -A POSTROUTING -i 192.168.5.100 -o 192.168.1.100 -j MASQUERADE
`

while iptables -L gives

enChain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination
ACCEPT     all  --  anywhere             anywhere

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

Am I missing something? What am I missing at configuring outlook with squid
