    Ubuntu 10.04, running Postfix, smarthost via Comcast.

    The following solution fixed my Postfix problem:

    nano /etc/hosts

    REMOVE localhost from IPv6 section

    # The following lines are desirable for IPv6 capable hosts
    ::1 localhost ip6-localhost ip6-loopback
    fe00::0 ip6-localnet
    ff00::0 ip6-mcastprefix
    ff02::1 ip6-allnodes
    ff02::2 ip6-allrouters
    ff02::3 ip6-allhosts

    Restart the networking
    /etc/init.d/networking restart

    Now I am able to send emails outside my local network.

    Same problem here, is there a drawback to this solution?
