Hi, I have a linux machine connected to the internet and to an internal network. I am running Sendmail and Ipchains. I have the following rules for Ipchains on port 25: # SMTP server (25) # ---------------- ipchains -A input -i $EXTERNAL_INTERFACE -p tcp \ --source-port $UNPRIVPORTS \ -d $IPADDR 25 -j ACCEPT ipchains -A input -i $LOCAL_INTERFACE_1 -p tcp \ --source-port $UNPRIVPORTS \ -d $LOCAL_IPADDR 25 -j ACCEPT ipchains -A output -i $EXTERNAL_INTERFACE -p tcp ! -y \ -s $IPADDR 25 \ --destination-port $UNPRIVPORTS -j ACCEPT ipchains -A output -i $EXTERNAL_INTERFACE -p tcp ! -y \ -s $LOCAL_IPADDR 25 \ --destination-port $UNPRIVPORTS -j ACCEPT The only other ports I also ACCEPT are 53 and 113. I can send and receive mail inside my network, but can´t receive or send E-mail to the internet. After examining the Messages log there are many lines with (Connection refused by server) when sendmail tries to connect to smtp servers on the internet. What am I missing here? Thanks in advance. __________________________________________________________________________ AcessoBOL, só R$ 9,90! O menor preço do mercado!
