我无法访问他们的机器，和所有的测试在本地运行正常。我试图用日志中提到的使用smtp服务器发送电子邮件，但我无法访问，也许是因为我在我的开发机器中，而不是他们的。从我的本地机器连接，我得到以下异常：

它们是相似的，但不相同。在本地我无法连接，但在客户端应用程序已连接，但无法读取响应。有人可以帮忙吗？谢谢！！！
在这里我可以提供我的邮件发件人的连接部分的细节：
input = MailSmtpSender.class.getResourceAsStream("/config/properties/mail.properties");
prop = new Properties();
prop.load(input);
prop.setProperty("mail.smtp.connectiontimeout", "5000");
prop.setProperty("mail.smtp.timeout", "5000");
prop.put("mail.smtp.starttls.enable", "true");
prop.put("mail.debug", "true");
Session session = Session.getInstance(prop);
MimeMessage message = new MimeMessage(session);
....(build message)
Transport t = session.getTransport(prop.getProperty("mail.smtp.protocol"));
try {
t.connect(prop.getProperty("mail.smtp.user"), prop.getProperty("mail.smtp.pass"));
t.sendMessage(message, message.getAllRecipients());
} catch (Exception e) {
...
} finally {
t.close();
}
mail.properties:(snippet）
mail.smtp.starttls.enable=true
mail.smtp.protocol=smtp
mail.smtp.useTSL=false
mail.smtp.auth=false
mail.smtp.port=25
mail.smtp.host=smtp-a.cm.es //this is what client need. I test locally with other servers and works fine.
感谢您的回复！也许我们会去他们的办公室查看，但离我的办公室很远。假如我不能在那里，我怎么检查他们的邮件服务器是否在侦听端口25？我本地尝试telnet，也是失败。和STARTTLS的一部分，我想我必须问他们的管理权吗？并感谢开发Javamail！太奇妙了。 – FaithReaper
是的，问问他们的管理员。也许你可以通过ssh或vpn访问他们的网络，以便测试而不必去那里。 –
