폼메일 발송이 안됩니다.....ㅠ.ㅠ

홈페이지에 제로보드를 사용하고 있습니다.

회원이 새로운 글이나 리플 및 코멘트를 남기면 제로보드상의 관리자에게 메일을 보내도록 설정을 했는데 새로운 글을 남기면 메일이 발송되기는 하는데 리턴되네요..ㅠ.ㅠ

게시판에서 글쓴 사람의 이름을 클릭하면 아웃룩이 아닌 폼메일을 이용하여 자동적으로 이름과 메일 주소가 입력되도록 했지만 그것 역시 "발송되었습니다"라는 메시지만 뜨지 실제로는 도착하지 않고..

서버의 root에게 메일이 리턴이 되요..ㅠ.ㅠ.
리턴 메일의 예를 남길께요 고수님들의 조언 부탁드립니다.
