私のラップトップ（Windows 10）または開発サーバー（CentOS）でこのJavaサービスを実行すると、 。私たちのライブサーバー（CentOSの）上でそれを実行したときに、私は次のエラーを取得する：私たちのライブサーバーでは、javax.mail.MessagingException：[EOF]取得devのサーバー上で期待どおりに動作します

は私の電子メールコード：
public void sendEmail(User user) {
to[0] = user.getEmail();
Properties props = new Properties();
props.put("mail.smtp.host", host);
props.put("mail.smtp.user", from);
props.put("mail.smtp.password", password);
props.put("mail.smtp.port", "587");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.debug", "true");
props.put("mail.store.protocol", "imap");
subject = user.getEmailBuilder().getEmailSubject();
try {
Session session = Session.getDefaultInstance(props,
new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(from,
password);
}
});
MimeMessage message = new MimeMessage(session) {
protected void updateMessageID() throws MessagingException {
if (getHeader("Message-ID") == null)
super.updateMessageID();
}
};
message.setFrom(new InternetAddress(from));
InternetAddress[] to_addresses = new InternetAddress[to.length];
for (int i = 0; i < to.length; i++) {
to_addresses[i] = new InternetAddress(to[i]);
}
message.addRecipients(javax.mail.Message.RecipientType.TO,
to_addresses);
String messageHtml = user.getEmailMessage();
message.setSubject(subject);
message.setContent(messageHtml, "text/html;charset=UTF-8;");
message.saveChanges();
user.setEmailMessageId(message.getMessageID());
log.info("Email message ID: " + message.getMessageID());
Transport transport = session.getTransport("smtp");
transport.connect(host, from, password);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
user.setEmailStatus(DistinctNotification.STATUS_SENT);
} catch (AddressException e) {
log.error("An AddressException occurred in EmailSender", e);
user.setEmailStatus(DistinctNotification.STATUS_READY);
} catch (MessagingException e) {
log.error("A Messaging exception occurred in EmailSender", e);
user.setEmailStatus(DistinctNotification.STATUS_READY);
}
}
エラーがこの行で発生します。
transport.connect(host, from, password);
編集：
私が知っている以前のビルドに戻しました事実は、おそらく数ヶ月前に働いた。それはもはや働く、私は同じエラーを取得します。
サーバーにアクセスできる他の同僚は、変更を加えていないと言います。
私はこれとどこに行くべきか全く分かりません。 私はtelnetを使ってgooglesサーバーに接続することに問題はありません。私は、確かに様々な港の点検をさらに進めるつもりですが、それは問題ではありません。 EDIT 2：ここでは
は問題だ：501-5.5.4 Empty HELO/EHLO argument not allowed, closing connection.
しかし、なぜこれが1台のサーバー上でのみ起こることでしょうか？コンソールから
追加のログは：

[JavaMailデバッグ出力]（http://www.oracle.com/technetwork/java/javamail/faq/index.html#debug）の表示内容は何ですか？ライブサーバーにファイアウォールはありますか？ [JavaMail FAQの接続デバッグのヒント]（http://www.oracle.com/technetwork/java/javamail/faq/index.html#condebug）をお試しください。 –
上記のエラーはログ内の唯一の例外です。 JavaMailのデバッグ出力を具体的に表示する別の方法はありますか？私は上記のエラーがそれだと思った。私は、telnetでグーグルメールサーバに接続できるので、ファイアウォールの問題などのようには思えません。また、このメールサービスの古いバージョンも機能しており、私はその点について何か変更したとは思わない。私の最初の考えは、コードが他のサーバーで動作するので、サーバー自体に何かでなければならないということです。しかし、どこに問題があるのか分かりません。 –
あなたは上のリンクの方法以外に別の方法を意味しますか？さて、あなたはjava.util.loggingを設定することができます。ロガーの詳細は各パッケージの[JavaMail javadocs pages]（https://javamail.java.net/nonav/docs/api/）にあります。デバッグ出力が得られない場合は、System.outがどこに行くのか把握する必要があります。これらの[一般的なJavaMailの間違い]（http://www.oracle.com/technetwork/java/javamail/faq/index.html#commonmistakes）も修正する必要があります。これにより、いくつかの問題が修正される可能性があります。 –
