邮件系统是Linux网络应用的重要组成，一个完整的邮件系统包括三个部分：底层操作系统（Linux Operation），邮件传送代理（Mail Transport Agent，MTA），邮件分发代理（Mail Delivery Agent，MDA），邮件用户代理（Mail User Agent，MUA）。 Postfix是一个非常优秀的MTA，她素以高效、安全的特点而著称。Postfix是作者在UNIX上所见过的MTA中在反垃圾邮件（Anti- Spam或Anti-UCE）方面做得最好的一个，甚至有很多公司在Postfix代码的基础上进行二次开发而推出反垃圾邮件网关产品。MTA的反垃圾邮件功能，实际上就是在MTA处理过程中对会话进行过滤。这个过滤不但过滤了发往自身的垃圾邮件，而且还防止了自身被恶意利用发送垃圾邮件。Postfix 实现了目前所有主要的MTA过滤技术。postfix是Wietse Venema在IBM的GPL协议之下开发的MTA（邮件传输代理）软件。和Sendmail相比Postfix更快、更容易管理、更灵活、更安全。

FLASH文件系统的源码，Flash memory is a nonvolatile memory, which allows the user to electrically program (write) and erase information. The exponential growth of flash memory has made this technology an indispensable part of hundreds of millions of electronic devices. Flash memory has several significant differences with volatile (RAM) memory and hard drive technologies which requires unique software drivers and file systems. This paper provides an overview of file systems for flash memory and focuses on the unique software requirements of flash memory devices.

The source code for this package is located in src/gov/nist/sip/proxy. The proxy is a pure JAIN-SIP application: it does not need proprietary nist-sip classes in addition of those defined in JAIN-SIP 1.1, you can substitute the NIST-SIP stack by another JAIN-SIP-1.1 compliant stack and it should interoperate. he proxy can act as presence server and be able to process NOTIFY and SUBSCRIBE requests. If this parameter is disabled, the proxy will simply forward those kind of requests following the appropriate routing decision.
