root@/deb73:~> ed /etc/exim4/update-exim4.conf.conf
    #dc_local_interfaces='127.0.0.1 ; ::1'
    dc_local_interfaces='127.0.0.1'
root@/deb73:~> update-exim4.conf
root@/deb73:~> service exim4 restart
    now exim4 NOT listening on ::1:25 only 127.0.0.1:25
root@/deb73:~> ed /etc/sysctl.conf
    net/ipv6/conf/all/disable_ipv6 = 1
root@/deb73:~> sysctl -p

Sent myself emails through my ISP both as root and mike.
Rebooted just to double check and am able to retrieve mail
so I think the problem is really solved and Iceweasel won't be slowed
down by checking for nonexistant ipv6 traffic.

Thanks again to you friendly helpers,
Mike
