Apache James是最好用的開源java郵件服務器之一，在配置smtp服務過程中，有些步驟不對的話郵件就發(fā)送不出去。

0.打開james-2.2.0\apps\james\SAR-INF\config.xml文件

1.transport

注釋掉

<!--mailet match="RemoteAddrNotInNetwork=127.0.0.1" class="ToProcessor">

<processor> relay-denied </processor>

<notice>550 - Requested action not taken: relaying denied</notice>

</mailet-->

使用smtp認證方式

2.dnsserver

輸入服務器的DNS IP，例如：

<server>202.96.134.133</server>

<server>202.96.128.110</server>
<server>202.96.128.68</server>
設置autodiscover為false
如果設置為自動探測的話，在我的機器上會報錯：
James.Mailet: RemoteDelivery: Temporary exception delivering mail (Mail1098776398187-0-to-somedomain.com: javax.mail.MessagingException: There are no DNS entries for the hostname somedomain.com.  I cannot determine where to send this message.

at org.apache.james.transport.mailets.RemoteDelivery.deliver(RemoteDelivery.java:398)
 
at org.apache.james.transport.mailets.RemoteDelivery.run(RemoteDelivery.java:912)
 
at java.lang.Thread.run(Thread.java:534)

3.修改root口令。account login="root" password="mypassword"

4.smtpserver

打開smtp認證

<authRequired>true</authRequired>

5.重新啟動James

6.telnet server-name 4555,增加用戶

7.就可以用outlook等發(fā)送郵件了。
