By default, sendmail only listens on the localloop:
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
But by default to allow sendmail to even work the iptables entry is:
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 25 -j ACCEPT
Without this, sendmail can't even connect to localloop. But should I handedit this line to something like:
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp -d 127.0.0.1 --dport 25 -j ACCEPT
And once you handedit iptables, you can't use the gnome firewall applet, I suspect...
