1。
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;public class MailAuthenticator extends Authenticator {
    public MailAuthenticator() {
    }    private String mUser;
    private String mPass;    public MailAuthenticator(String userName, String passWord) {
        super();
        mUser = userName;
        mPass = passWord;

        }        this.getSession().getTransport("smtp").send(mailmsg);
        this.getSession().getTransport("smtp").close();
        return true;
        /*
             }
             catch (Exception ex) {
               logger.debug(this.getUserId() + "发送邮件失败了" +
                           System.currentTimeMillis());
               ex.printStackTrace();
               logger.debug("error",ex);
             }*/

    }    /**
     * test

Answer 1

props.put("mail.smtp.host","qzsoft.cn");
我设置的服务器是qzsoft.cn
为什么只有[email protected]的邮件能发送其它的则不行呢如163,126等
