161.84.252.211.in-addr.arpa     name = mail.kbsoft.co.kr

84.252.211.in-addr.arpa nameserver = rev1.kornet.net

84.252.211.in-addr.arpa nameserver = rev2.kornet.net

rev1.kornet.net internet address = 211.216.50.170

rev2.kornet.net internet address = 211.216.50.180

"ptr" 등록은 데어 있는데 어떡해 조치해야 되는지요 ?

검색해 보니

해외 차단 "BarracudaCentral.org - Technical Insight for Security Pros" 에서 해제 신청있는 것 같은데

다른 방법이 있나요 ?

수고하세요.
