I have found that many "abuse" email addresses indicated in WHOIS databases actually are fake e-addresses.

One of them is gestionip@TELEFONICA.NET.PE (because my company has received many many spams originated from its network so I wrote a spam complaint to this e-address but the mail was rejected for non-existent mailbox!)

What can we do in this case?

Thanks

$ whois -h whois.ripe.net -- "-B -G -r -i abuse-mailbox gestionip@TELEFONICA.NET.PE"
