Hello,
my systems get attacked from several IPs from Georgia (Countrycode=GE, RIR=RIPE).
My Abuse Reports to the abuse address (ib(a)caucasus.net) of the
responsible ISP for the attacker IPs (caucasus.net) just bounce:
#ID: <SCC9B>
#Mail From: <security(a)mutluit.com>
#Rcpt To: <ib(a)caucasus.net>
#Server: <mail.caucasus.net> [62.168.168.131]
#
#[<02>] The reason of the delivery failure was:
#
#550 5.7.1 <security(a)mutluit.com>: Sender address rejected: Blocked by postmaster
What to do in this case?
