Exchange - 拆分通讯组

Question

我想向通讯组发送电子邮件，并确保收件人会收到特别发送给他们的电子邮件。意思是：在“收件人”字段中，我希望他们只能看到他们的电子邮件地址，而不是粗体字母的组名。

我正在为Exchange构建一个主题路由器DLL，我需要将发送到组的电子邮件分成单独的电子邮件消息。我正在研究Exchange 2010.任何想法？

我想做这样的事情：

messageEventArgs.MailItem.Message.To = messageEventArgs.MailItem.Recipients

但不幸的是messageEventArgs.MailItem.Message.To是只读的......

还有其他想法吗？

以下是一些请求的示例代码：

       void ownRoutingAgent_OnResolvedMessage(ResolvedMessageEventSource   source, QueuedMessageEventArgs messageEventArgs)
 {
      bool forwardToSeg = false;

      if (true) EventViewerLogger.WriteInfo("FromAddress: " + messageEventArgs.MailItem.FromAddress.ToString());
      if (true) EventViewerLogger.WriteInfo("SecureSenders: " + m_SecureSenderAddress);

      distGroupList = generateDistGroupList();

      // Change origional Sender EMail Address to a random sender from the list of SEG users
      foreach (string senderAddr in m_SecureSenderAddress.Split(','))
      {
          //Check if sender equals to a secure sender
          if (senderAddr.ToUpper() == (messageEventArgs.MailItem.FromAddress.ToString().ToUpper()))
          {
                 Random rnd = new Random();
                 int numOfUser = rnd.Next(0, senderAddresses.Length);
                 messageEventArgs.MailItem.FromAddress = new RoutingAddress(senderAddresses[numOfUser]);

                 forwardToSeg = true;

     //Check if recepient is a distrebution group

                 // run over all recipients list
                 //foreach (EnvelopeRecipient recp in messageEventArgs.MailItem.Recipients)
                 //{
                     // run over excluded members list
                     foreach (MyClass disGrp in distGroupList)
                     {
                         // Checks if Recipients contain an  e-mail group),
                         // if yes, does not route to seg.
                         if (messageEventArgs.MailItem.Message.To.ToString().ToUpper() == disGrp.emailAdress.ToUpper())
                         {
                             messageEventArgs.MailItem.Message.To.Add*******
                                 = messageEventArgs.MailItem.Recipients
                             //create a method that extracts group members and saves them in an array
                             //delete group address from mail-recipients

                             //messageEventArgs.MailItem.Recipients;
                             return;
                         }
                     }
                 //}
           }
      }

您可以从该组中获取电子邮件列表，然后发送邮件。以下代码段将获取单个邮件ID。

    string groupName = "somegroup";
    string domainName = "somedomain";

    using(PrincipalContext ctx = new PrincipalContext(ContextType.Domain, domainName))
    {
        using(GroupPrincipal grp = GroupPrincipal.FindByIdentity(ctx, IdentityType.Name, groupName))
        {
            var sams = from x in grp.GetMembers(true) select new {x.SamAccountName, };
            var users = from sam in a.Distinct()
                let usr = UserPrincipal.FindByIdentity(ctx, IdentityType.SamAccountName, sam)
                select new { usr.SamAccountName, usr.DisplayName, usr.EmailAddress};
            //users is now populated with the e-mail IDs
        }
    }

此外，您仍然可以使用单个邮件并将电子邮件地址保留在BCC字段中。不确定要求是什么..
