Zenwalk: problem enabling ports 25 & 110 for users to use thunderbird's webmail ext.

Hi All!
I have just installed webmail extension ( for Thunderbird and I am having a problem. When I was configuring the server option, I noticed that port 110 and 25 generated error message. In other words, these two ports are not open. I verify this with nmap. I noticed on that configuration screen that it said "some OS's block ports below 1024". I am running this at the user level, so certainly some ports will be blocked.

How do I open these two ports for the user? I have done the iptables at the root level, but it doesn't seem to solve the problem.

iptables -A INPUT -s 0/0 -p tcp -m state --state NEW -m tcp -d --dport 25 -j ACCEPT
iptables -A OUTPUT -s -p tcp -m state --state NEW -m tcp -d 0/0 --dport 25 -j ACCEPT
iptables -A INPUT -s 0/0 -p tcp -m state --state NEW -m tcp -d --dport 110 -j ACCEPT
iptables -A OUTPUT -s -p tcp -m state --state NEW -m tcp -d 0/0 --dport 110 -j ACCEPT
I am running Zenwalk 4.6.1 and I am not running any servers. I am just using it as a desktop OS.
