[GTALUG] Messages are bouncing

[ac]

mailmain includes the receiving IP number, irrespective of whether it
is ipv6 or ipv4, it is not an ipv6 or ipv54 issue :)

it is because 2600:3c03:e000:173::1 is in an abuse range. (probably
because of the snowshoe from linode) 

if mail.flamy.ca was an ipv4 that was also abusive or non responsive to
abuse - the problem would be the same...

the list should probably also be using the spamhaus 'drop' rbl..
but you are not because your range is listed? :)

the list ipv4 is nice and clean:
http://multirbl.valli.org/lookup/69.164.222.247.html - and the specific
ipv6 (2600:3c03:e000:173::1) is also clean, the range is in a 'drop'
range.... - as ipv6 starts becoming more common, many ipv6 email
servers would have to get better hosting / ip ranges, if they want to
send email reliably - as the ipv6 spectrum is too large to function
easily on the same basis as ipv4...
