This sounds more like a general networking problem, particularly to do
with name resolution.  Starting CUPs needs name resolution to work, so
does X, and many applications that'll use X, and particularly a mail
client.

The iptables message sounds like something I see at every boot related
to IPv6, which I don't expect to work because my router, and I think my
ISP, don't support it.  I can trigger the same error message like this:

# service ip6tables restart
Flushing firewall rules:                                   [  OK  ]
Setting chains to policy ACCEPT: filter                    [  OK  ]
Unloading ip6tables modules:                               [  OK  ]
Applying ip6tables firewall rules: Warning: never matched protocol: 51. use extension match instead.
                                                           [  OK  ]

I will, fairly confidently, say that this is unimportant for most
people.

For your issue I strongly suspect that you need to check whether your
machine name resolves.  Look into your hosts file, your resolv.conf
file, and the addresses applied to your network interfaces.

I think you're chasing a red herring.  Anyway, you cannot remove
SELinux, there was a long thread about this not long ago.  You can put
it into permissive mode, where it's *supposed* to not stop anything,
just log it.  Or you can put it into disabled mode.
