iptables + mail

Привет всем !! Возникла большая трабла с постой.
Стоит Debian +Squid+ядро 2.6.8+iptables Вообщем пользователи могут ходить в Инет но не могут забирать и отсылать почту. Своего почтового сервера нет! 
smtp 83.149.205.222 
POP3 193.124.133.208 
Ниже iptables-save/
Да еще один вопрос надо прокинуть машину из инета внутрь сети по всем портам.
