英文:
java.lang.RuntimeException: com.sun.mail.util.MailConnectException: Couldn't connect to host error
问题
以下是翻译好的内容：
我正在尝试使用Java Mail API从我的公司Outlook发送电子邮件，但是我遇到了连接被拒绝的错误。我已经检查了主机信息和凭据，它们是有效的。我正在使用来自Maven的1.6.2版本的javax.mail。
编辑更新：现在我考虑了一下，因为我是从本地尝试这个操作的，我怀疑这是防火墙问题造成的。我只想听听那些以前遇到过这种情况的人的见解，以及他们是如何解决的。

java.lang.RuntimeException: com.sun.mail.util.MailConnectException: 无法连接到主机，端口：
SMTP.ABC.DEF.COM，587；超时-1；
嵌套异常是：
java.net.ConnectException：连接被拒绝：连接

I am trying to send email from my company's outlook using Java Mail API and I am getting this connection refused error. I checked host information and credentials and they are valid. I am using 1.6.2 version of javax.mail from Maven.
Edit Update : Now I thought about it and since I am trying this from my local and I am suspecting this is because of the firewall issue. I just want some insights from people who have experienced this before and what did they do to resolve.
