使用 Cmdlet Extension Agents 自动发送用户欢迎邮件




论坛上经常有朋友会问到，如何在创建新邮箱的时候，同时发一封欢迎邮件呢？在Exchange 2010之前，通常的做法是:
1. 写一个邮件发送脚本，然后利用scheduler task 定期调用脚本。
2. 存一份 .msg 文件，然后手工或者利用脚本来做。
3. 利用Word 的mail merge 功能

进入Exchange 2010 时代，终于可以实现自动化了。前两天看到一老外写的关于Cmdlet Extension Agents的使用，觉得蛮有意思的，自己测试了下，果然不错。下面是一些分享。

首先，我们需要创建一个Receive connector 来接受从特定IP地址段来的 free relay。命令行中的IP地址段可自行修改，请注意此处的安全隐患。
  1. New-ReceiveConnector -Name "Internal Relay" -Bindings 0.0.0.0:25 -RemoteIPRanges 127.0.0.1,192.168.100.1-192.168.100.255 -AuthMechanism None -Enabled $true -Fqdn "ex2010cas01.mcmhost.com" -PermissionGroups AnonymousUsers -Server ex2010cas01 | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "ms-Exch-SMTP-Accept-Any-Recipient"
复制代码
第二步，创建一个脚本来发送欢迎邮件到特定邮箱。我们为这个脚本取名为send-mail.ps1, 命令行参数为:
  1. send-mail.ps1 –mailboxname <邮箱名>
复制代码
代码如下, 请修改变量定义中的邮件地址，请注意邮件中会自动插入出用户的用户名，邮件地址等信息，另外，可自行修改声明。第三步之前，可先行运行此脚本，保证脚本能正常工作。

第三步, 去到C:\Program Files\Microsoft\Exchange Server\V14\Bin\CmdletExtensionAgents　目录下（如果不是缺省安装路径，可自行修改）。创建一个XML文件ScriptingAgentConfig.xml 。

XML文件内容如下,其作用是当完成new-mailbox这个命令后，自动调用c:\temp\send-mail.ps1脚本发送欢迎邮件，并且禁止邮箱的IMAP和POP3访问。这里的功用可无限引申出去(注意，在某些时候script agent的优先级需要比provisionagent的优先级高，比如对database做操作的命令，此处就不赘述了)。

  7.                                                                 c:\temp\send-mail.ps1 -mailboxname $newmailbox
  8.                                                                 Set-CASMailbox $newmailbox -IMAPEnabled $false -POPEnabled $false
  9.                                                 }

第四步，关闭所有服务器上目前打开的EMS和EMC。然后拷贝该XML去您环境中的每一个Exchange 服务器。别怪我没告诉你噢，等下跟我说你打不开EMC了。

第五部，使用下面命令创建一个新用户（也可用界面创建）。请自行修改 OU路径和用户名等参数。
  1. New-Mailbox -Name 'Exchange 2010 user08' -Alias 'exchange2010user08' -OrganizationalUnit 'MCMHost.com/MCM/Users' -UserPrincipalName '[email protected]' -SamAccountName 'user08' -FirstName 'Exchange 2010' -Initials '' -LastName 'user08' -Password 'System.Security.SecureString' -ResetPasswordOnNextLogon $false

第六步，登录OWA, 查看效果:
