Are they errors? if so, What they mean?*netset: cannot include 0:0:0:0:0:0:0:1/128 as it has already been included netset: cannot include 0:0:0:0:0:0:0:1/128 as it has already been included*it means that the ipv6 localhost address has already been included.Ignore this, these are not the droids you are looking for.
I think this is also a bug in NetAddr-IP... See https://issues.apache.org/SpamAssassin/show_bug.cgi?id=6681 and "Avoid versions 4.034 to 4.035 and 4.045 to 4.054". Regards, KAM
