我在网上搜索过，但找不到有效的解决方案。我收到以下异常：
Authentication failed; nested exception is javax.mail.AuthenticationFailedException: 535 5.7.3 Authentication unsuccessful
下面是我的输出：

我正在使用 Spring 3.0 来使用 JavaMail API，如下所示：
<bean id="mailSenderBean" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host" value="NB-EX10-1.example.com"></property> <!-- localhost-->
<property name="username" value="myusername"></property>
<property name="password" value="password"></property>
<property name="javaMailProperties">
<props>
<prop key="mail.smtp.port">25</prop>
<prop key="mail.smtp.auth">true</prop>
<prop key="mail.smtp.starttls.enable">false</prop>
<prop key="mail.transport.protocol">smtp</prop>
<!-- <prop key="mail.smtp.auth.ntlm.domain"></prop>-->
<prop key="mail.debug">true</prop>
</props>
</property>
</bean>
我们使用的是 Microsoft Exchange Server 2010。我只需要使用 NTLM 进行连接。
任何帮助，将不胜感激。
