Squirrelmail and IPTables

Hello all,

I just reconfigured IPTables to accept connections for all known mail ports. My
problem is when sending through squirrelmail it says temporary problem.  Now it
worked before I implemented IPTable rules so I am assuming it is a IPTables
entry that is needed.

Basically it needs to except from localhost, am I right??

Is this what I need to enter into IPTables so that squirrelmail can send mail?
iptables -A INPUT -p udp -m tcp -s 0/0 -d 0/0 --sport 25 -j ACCEPT

Thanks,
Will
