Public bug reported:
Hi
We have a number of IPv6 single stacked servers (i.e. they do not have
IPv4 connectivity) running Ubuntu server 12.04 (LTS). It seems that
Nullmailer is not able to send e-mails via IPv6. I have tested it on
Ubuntu 13.10 and it works (same network, configuration and so on).
The log says:

An e-mail address has been configured in the adminaddr file.
It is not a firewall-issue. When I test with tcpdump no packets are
being transmitted from the server to the relay host. As previously
stated it works on Ubuntu 13.10 (Version: 1:1.11-2) on the same network
with the identical configuration.
