[imp] Question of Firewall + IMP on Fedora Core 1 / Redhat 7.x Linux System

[edwardspl at ita.org.mo]

Dear All,

I'm using IMP 3.2.3 :
protocol : imap/notls , pop3/notls
port : 143 , 110

System : Fedora Core 1 / Redhat 7.x

Firewall ( iptables rules ) :

/sbin/iptables -P INPUT DROP
/sbin/iptables -A INPUT -i eth0 -s 0/0 -p tcp --dport 143 -j ACCEPT

error message from horde/imp :

server="Public_IP_Address" user="edward"
mailbox="{Public_IP_Address:143/imap/notls}INBOX"
array(1) {
[[0]=>
string(59) "Connection failed to Public_IP_Address: Connection timed
out"
}

Many thank for your help !

Edward.
