폼메일입니다. 알수 없는 오류가 납니다.

안녕하세요.

이곳 Q/A로 올리는것이 분류가 맞는지 모르겠네요.

폼메일로 전체 메일을 발송하는 소스가 있습니다.

mysql DB에서 발송 리스트를 가져와서 센드메일로 보내는것인데요.

이상하게 오류가 나서 메일이 하나도 발송되지 않습니다.

계속 해서

From:
Content-type: text/html; charset =euc-kr

메시지만 나옵니다.

같은 소스를 이용해서 한두개 정도의 리스트에 메일을 발송하게 하면 제대로 나갑니다.

혹시나 해서 속도 때문에 발송이 안되나 해서 100건당 sleep 10를 주었습니다.

그래도 발송이 안되고 오류만 나네요. 발송리스는 3000건 조금 넘습니다. 쩝...

경험해 보신분 있으시면 해결 방법좀 알려주세요.

화이트 도메인은 신청되어 있구요. 서버는 리눅스입니다.

미리 감사합니다.
