问题描述

我有以下问题.我有一个Seam Web应用程序，该应用程序具有电子邮件撰写和使用Javamail发送功能.该应用程序可以在我的本地JBoss应用程序服务器中正常发送邮件，但不能在myhosting.com VPS中安装的JBoss服务器上运行.我读到该问题可能是因为我要连接的Web服务器或URL没有来自授权CA的有效证书，但是我运行了一个实用程序(

I have the following problem. I have a Seam web application which features e-mail composition and sending using Javamail. The application sends mail just fine in my local JBoss application server, but it doesn't work on the JBoss server installed in my myhosting.com VPS. I read that the issue may be because the web server or the URL to which I'm trying to connect does not have a valid certificate from an authorized CA, but I run an utility (http://cold-caffein.blogspot.com/2011/07/looks-like-article-no-more-unable-to.html) that lets me verify the certificates and they appear to be fine (I'm connecting to Gmail).

设置会话属性的相关代码如下:

The relevant code for setting Session properties follows:

props.put("mail.smtp.auth", "true");
props.setProperty("mail.smtp.starttls.enable", "true");

我了解到导致此问题的另一个原因可能是将mail.smtp.starttls.enable设置为true，但是如果我省略了第二行，则该代码根本不起作用(在我的本地服务器或VPS中)或将属性设置为false.

I read that another cause for the issue could be using mail.smtp.starttls.enable set to true, but the code doesn't work at all (in my local server or in the VPS) if I omit the second line or set the property to false.

我不知道问题是否与myhosting提供的mail2web邮件服务有关(请看下面我提供的两个日志中的第9行，这是事情开始有所不同的地方).这是本地Javamail日志和VPS的服务器日志(后者显示了我遇到的错误):

I don't know if the problem has something to do with the mail2web mail service that myhosting offers (look at line 9 in both logs I'm providing below, it's where things start going different). Here are the local Javamail log and the VPS' server log (the latter shows the error I'm getting):
