Hi Bernhard
Is AS21494 known to be irresponsive to abuse complaints? Does anyone know some way to get in contact with them?
I got the same issue a time ago
I'm seriously considering blackholing the whole ASN,
I didn't go that far but the nets 80.253.80.0/24 80.253.81.0/24
and the hosts matching /zux(\d+-)(\d+-)\d+.adsl.green.ch$/
are blocked by all our mailservers...
Any input is appreciated.
Thanks, Bernhard
Regards André
