这样一个项目，希望把后三项删掉。

ExtMail是何智强同学的个人作品，GPL授权。装了一套，感觉还不错，有很多值得借鉴的地方：

• 使用cur而非new来保存parse过的邮件
• 保存邮件信息到cache

等等。

Today, Wietse Venema has announced postfix 2.2.0-RELEASE. To quote him:

The official Postfix 2.2 release adopts widely used third-party patches and a bunch of new functionality that was developed over the past year.Below is a summary of the changes. These and more are detailed in the RELEASE_NOTES document, which also describe the incompatible changes that you should be aware of BEFORE upgrading from Postfix
2.1 or earlier.

• TLS and IPv6 support are now built into Postfix, based on code
  from third-party patches.

• Extended query interface for LDAP, MySQL and PostgreSQL with free
  form SQL queries, and domain name filters to reduce unnecessary
  lookups.
