Commons 전자 메일이 올바른 호스트에 연결되지 않았습니다.

Question

원격 메일 서버에 연결하려했지만 어떻게 든 전자 메일/JavaMail은 항상 localhost에 연결을 시도합니다. 왜???

Email email = new SimpleEmail(); 
    email.setHostName("mailserver.com"); 
    email.setSentDate(new Date()); 
    email.setAuthentication("admin@mailserver.com", "password"); 
    email.setSubject("testing using simple mail"); 
    email.setMsg("test email"); 
    email.setFrom("*******@gmail.com"); 
    email.addTo("*****@gmail.com"); 
    email.setDebug(true); 
    email.send(); 

은 항상 다음과 같은 예외를 얻을 :

Answer 1

나는 문제가 썬/오라클은 JavaMail 릴리스 중 하나에 있다는 것을 기억하는 것 같다.

어떤 버전의 javamail (즉, mail.jar) 및 어떤 commons-email 버전을 사용하고 있습니까?

두 버전의 최신 버전으로 업그레이드하면 작동 할 수도 있습니다.
