无法使用EWS Java API发送电子邮件

Question

我正在使用EWS在Exchange 2010上发送电子邮件，如下所示：

ExchangeService service = new ExchangeService();
ExchangeCredentials credentials = new WebCredentials(email, password);
service.setCredentials(credentials);
service.setUrl(new java.net.URI("https://" + host
    + "/EWS/Exchange.asmx"));
service.setTraceEnabled(true);

EmailMessage msg = new EmailMessage(service);
msg.setSubject("Hello world!");
msg.setBody(MessageBody.getMessageBodyFromText("Sent using the EWS Managed API."));
msg.getToRecipients().add("email");
msg.send();

邮件未发送到收件箱，我不知道问题出在哪里。在我启用跟踪之后，我得到了以下信息：

<Trace Tag="EwsRequestHttpHeaders" Tid="1" Time="2012-10-14 11:13:46Z">

请建议如何解决此问题。

Answer 1

exchange服务器正在响应一切正常：

<?xml version="1.0" encoding="utf-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header>
    <h:ServerVersionInfo MajorVersion="14" MinorVersion="1" MajorBuildNumber="218" MinorBuildNumber="14" Version="Exchange2010_SP1" xmlns:h="http://schemas.microsoft.com/exchange/services/2006/types" xmlns="http://schemas.microsoft.com/exchange/services/2006/types" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"/>
  </s:Header>
  <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <m:CreateItemResponse xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">
      <m:ResponseMessages>
        <m:CreateItemResponseMessage ResponseClass="Success">
          <m:ResponseCode>NoError</m:ResponseCode>
          <m:Items/>
        </m:CreateItemResponseMessage>
      </m:ResponseMessages>
    </m:CreateItemResponse>
  </s:Body>
</s:Envelope>

您应该在Exchange端进行检查，或者向Exchange服务器管理员询问正在发生的事情(例如，一些垃圾邮件过滤或其他任何情况)，因为从代码的角度和SOAP请求/响应的角度来看，没有任何问题。

          <t:Message>
            <t:Subject>Hello world!</t:Subject>
            <t:Body BodyType="HTML">Sent using the EWS Managed API.</t:Body>
            <t:ToRecipients>
              <t:Mailbox>
                <t:EmailAddress>adamb@fabrikam.com</t:EmailAddress>
              </t:Mailbox>
            </t:ToRecipients>
          </t:Message>

请检查adamb@fabrikam.com的收件箱或与交换管理员交谈，以查看邮件队列、筛选器、许多其他可能阻止电子邮件发送的内容等。您发布的代码没有任何问题。
