当客户通过我们的（Magento CE 1.8.1.0）网站下订单时，该订单的副本应该密送给我们的销售经理。我说“应该”是因为这是一个有效的功能在老管理员离开之前。
我最近在一家小公司找到了一份网页开发人员的工作。他们在雇佣我时没有告诉我的是，除了其他日常工作外，我还将负责管理服务器。说实话，我对这些事情并不陌生，但这是我第一次使用机架服务器/控制台。
不过，我相信我能够解决您提供的任何解决方案。
详细描述：
我开始工作后不久，我们的服务器崩溃了，需要重新启动服务器。重新启动后，我们注意到我们网站上的一些功能无法使用，但除了这个之外，其他所有功能都已清理干净。我不得不在我们的服务器上创建一个帐户以获得 root 访问权限。
当客户下订单时，我们的网站软件（Magento CE 1.8.1.0）配置为将客户订单电子邮件密送给我们的销售经理。我们使用 Microsoft Exchange 2007 Server 来处理邮件，该服务器托管在另一台机器（内部）上，我无法访问 ATM，但我确信如果需要我可以访问。据我所知，所有其他外部电子邮件都可以正常工作。只有内部电子邮件地址无法发送。我知道这一点是因为我也通过我们的网站测试了我自己的内部地址。我使用内部电子邮件建立了一个帐户，下了测试订单，但从未收到电子邮件。我将该帐户的电子邮件更改为外部 GMail 帐户，并按预期收到了电子邮件。让我们深入了解日志和配置。
出于隐私/安全原因，名称已更改为以下：
domain.com = Our Top Level Domain.
email.local = Our Exchange Server.
example.com = ANY other TLD.
OLDadmin = Our previous Server Administrator.
NEWadmin = Me.
SALES@ = Our Sales Manager.
Customer# = A Customer.
