spamassassin not using IPv6

[Spacedust]

I got tons of these:

Aug 31 15:20:31 online spamc[25595]: connect to spamd on ::1 failed, retrying (#1 of 3): Connection refused

Maybe related to your issue is http://www.linuxquestions.org/questions/linux-server-73/spamassassin-trouble-4175503795/

See:

[root@online sysconfig]# telnet 2a01:4f8:151:7453::3 783
Trying 2a01:4f8:151:7453::3...

How to install these ?

Preferably a perl module IO::Socket::IP is used (if it is available) for
network communication regardless of a protocol family - for DNS queries,
by spamd server side, and by a client code in Mail::SpamAssassin::Client.
As a fallback when the module IO::Socket::IP is unavailable, an older
module IO::Socket::INET6 is used, or eventually the IO::Socket::INET is
used as last resort.

If spamd fails to start with an 'Address already in use' message, please
install perl module IO::Socket::IP, or deintall IO::Socket::INET6, or
specify a socket bind address explicitly with a spamd --listen option.
See bug 6953 for details.

This is a trick to install perl modules. Let say module is IO::Socket::IP and try install this module with 'yum install perl-IO-Socket-IP'.

Summary     : Family-neutral IP socket supporting both IPv4 and IPv6
Description :
This module provides a protocol-independent way to use IPv4 and IPv6
sockets, intended as a replacement for IO::Socket::INET. Most constructor
arguments and methods are provided in a backward-compatible way. For a
list of known differences, see the IO::Socket::INET INCOMPATIBILITES
section below.
