1.exchange郵件
微軟的Exchange郵件服務不同與一般的郵件server，他不能簡單使用SmtpClient等組件實現郵件收發的功能。
那么怎么通過Exchange服務發送郵件呢?
微軟的Exchange服務都有webservice接口, 通過其提供的webservice發送郵件也是最簡單的方法。
驗證Exchange服務的webservice是否正常：https://xx.xxxxx.com/ews/exchange.asmx， 能打開就是正常。可能須要登錄。
可是這個webservice不同於普通的webservice，不能簡單的加入web引用來調用。
首先我們須要下載一個Microsoft.Exchange.WebServices.dll，然后引用到我們的項目里邊，是個msi，安裝好之后就有那個dll，然后就能夠開始了。。
以下是一個發送郵件的樣例：
using Microsoft.Exchange.WebServices;
using Microsoft.Exchange.WebServices.Data;
private void SendEmail()
{
ExchangeService service = new ExchangeService();
// 獲取身份驗證, 能夠嘗試你的郵箱名, 域用戶ID等
// user: 登錄username，郵箱登錄ID或者域登錄ID
// password：你懂的
// domain：域，不是域名，域用戶的的話就得填這個，選填
service.Credentials = new NetworkCredential("user", "password", "domain");
service.TraceEnabled = true;
service.AutodiscoverUrl("zhangsan@yuming.com"); // 這個是發件然的郵箱地址，完整的(xx@dd.com).
EmailMessage message = new EmailMessage(service);
message.Subject = "Email的主題";
message.Body = "Email的內容";
message.ToRecipients.Add("收件人的郵件地址");
message.Save();
message.SendAndSaveCopy();// 發送
}
2.smtp 郵件
