[anti-abuse-wg] Abuse contact of 85.95.235.0 - 85.95.235.255 not working (emails bounce)

Abuse email contact of 85.95.235.0 - 85.95.235.255 not working (emails bounce):

The abuse contact email address of the the following RIPE member
isn't functioning for more than 3 weeks now as all mails to that address bounce:
"
SMAIL SMTP-Send MX = "mail.atalaybilisim.com." SMTP = "mutluit.com" From = "security at mutluit.com" To = 
"dns at atalaybilisim.com" Failed !
SMTP-Error = "550 Requested action not taken: mailbox unavailable or not local"
SMTP-Server = "mail.atalaybilisim.com."
"

Additionally, they have given their IP 85.95.235.101
the DNS hostname "localhost.mail.localdomain" .
The same with their second IP 85.95.235.102.

Is this legal? Isn't that an indication for a "mail server hacker collective"?

The above said two IPs are among the bounced abuse reports.
