Comments
in other news, the sky is blue.
I assumed you reported this already to their abuse team.?
ok
team email-alias
There's very few companies that have a dedicated abuse employee let alone a team..
Nothing new. What I expect is those emails are sent from IPv6 addresses.
Optimistic of you to think they properly action any reports.
That's impossible, considering Colocrossing doesn't have IPv6 and actively seems to avoid any question related to it.
That is what they promised all those years ago. Nothing is impossible. Our future generations will see it.
My postfix will check if it is from colocrossing network,all send to quarantine.
If it is from hostwinds,then 100% reject mode.
I reported to hostpapa abuse (from whois info got hostpapa email).
Then contacted colo via abuse form and they blocked within 1 day
Last time I reported they blocked very fast
All those
.cnaddresses -- this doesn't help against the negative stereotypes, unfortunatelypeople call them ColonCrossing for a reason.
All these CN domain same persion

I confirm that abuse works. But you need to contact them directly from their site.
Now colo's ips have hostpapa listed there. Do not contact hostpapa, endless useless conversations like "we are working on the problem", despite they just do nothing.
So why don't you report the abuse to the domain registrar Aliyun as well?
all from [email protected]
