I am a newbie to ubuntu servers & i installed iRedmail with perfect installation. i can simply send emails internally through the server, but have difficult sending to other domains, e.g. google/yahoo etc.

Please help me with simple steps and i am new to this.

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
