I'm trying to setup/config Postfix on RH73 (one small step at a time); I can sent mail out from the host, but, am struggling to make it recieve anything external;
from command line on the server itself , I can see Postfix is waiting: # telnet myserver.sbt.net.au 25 Trying 127.0.0.1... Connected to myserver.sbt.net.au. Escape character is '^]'. 220 myserver.sbt.net.au ESMTP Postfix ehlo roman.sbt.net.au 250-myserver.sbt.net.au 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-XVERP 250 8BITMIME quit 221 Bye Connection closed by foreign host. BUT, If i try to telnet from another host on same LAN, I get 'connection refused' I am not sure if it's my ipchains firewall ? or, Postfix setup ? is this ipchains OK for smtp ? :input ACCEPT :forward ACCEPT :output ACCEPT -A input -s 0/0 -d 0/0 3306 -p tcp -y -j ACCEPT -A input -s 0/0 -d 0/0 10000 -p tcp -y -j ACCEPT -A input -s 0/0 -d 0/0 25 -p tcp -y -j ACCEPT -A input -s 0/0 -d 0/0 80 -p tcp -y -j ACCEPT -A input -s 0/0 -d 0/0 21 -p tcp -y -j ACCEPT -A input -s 0/0 -d 0/0 22 -p tcp -y -j ACCEPT -A input -s 0/0 -d 0/0 23 -p tcp -y -j ACCEPT -A input -s 0/0 67:68 -d 0/0 67:68 -p udp -i eth0 -j ACCEPT -A input -s 0/0 67:68 -d 0/0 67:68 -p udp -i eth1 -j ACCEPT -A input -s 0/0 -d 0/0 -i lo -j ACCEPT -A input -p tcp -s 0/0 -d 0/0 0:1023 -y -j REJECT -A input -p tcp -s 0/0 -d 0/0 2049 -y -j REJECT -A input -p udp -s 0/0 -d 0/0 0:1023 -j REJECT -A input -p udp -s 0/0 -d 0/0 2049 -j REJECT -A input -p tcp -s 0/0 -d 0/0 6000:6009 -y -j REJECT -A input -p tcp -s 0/0 -d 0/0 7100 -y -j REJECT Voytek Eymont -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
