그누보드5 메일알림 관련 질문합니다 호스팅 마다 되는곳 있고 안되는곳있네요..

기존에 주문알림 , 상담신청 알림 , 문의 알림, 관리자에 받을 이메일 각각 지정해놓으면

카페 24 또는 가비아 한국 호스팅 쪽에다가 그누보드 셋팅 하면  메일이 오는데

해외 호스팅어쪽 셋팅 했을시 메일이 오지가 않습니다.

한국 호스팅쪽은 다음 지메일 네이트 네이버 다 잘 들어오는데 호스팅어만 그렇습니다.

PHP 버전 5.1 그누보드 5.0.38 PHP 메일러 2.0.4 입니다 .  호스팅어는 php5.2~7.1 지원 ,

아래 사양 첨부와 / 메일 소스 코드 첨부합니다.
