Java mail test

mail局域网Exchange服务器测试代码，仅限发送到domain内用户，发送外网需要exchange设置白名单， ref:
解决方案：

Exchange 2003:
Open the Exchange System Manager
Go in Administrative Groups -> Administrative group name -> Server -> Server name -> Protocols -> SMTP
Right click on Default SMTP Virtual Server -> properties
Access tab -> Relay button
Select "only the list below" and add the domain and\or IPs of your JIRA server
Exchange 2007:
For Exchange 2007, create a second receive connector for external addresses as described in 2007[url=https://confluence.atlassian.com/display/JIRA/How+to+Set+Up+SMTP+Relay+in+Exchange+2007]How to Set Up SMTP Relay in Exchange [/url].
