Postfix 邮件发送服务器

Postfix 是一种电子邮件服务器，它是由任职于IBM华生研究中心（T.J. Watson Research Center）的荷兰籍研究员Wietse Venema为了改良sendmail邮件服务器而产生的。最早在1990年代晚期出现，是一个开放源代码的软件。

Postfix 稳定版 3.0.3 发布，同时发布遗留版本 2.11.7, 2.10.9 和 2.9.15。

Postfix 2.9.15 改进：

• The postmulti command produced an incorrect error message.

• The postmulti command now refuses to create a new MTA instance when the template main.cf or master.cf file are missing. This is a common problem on Debian-like systems.

• False alarms while scanning the Postfix queue. Fixed by resetting errno before calling readdir().  This defect was introduced 19970309.

• The Postfix Milter client aborted with a panic while adding a message header, after adding a short message header with the PREPEND action. Fixed by invoking the header output function while PREPENDing a message header.

Postfix 2.10.9 改进：

• Turning on Postfix SMTP server HAProxy support broke TLS wrappermode. Fixed by temporarily using a 1-byte VSTREAM buffer to read the HAProxy connection hand-off information.

Postfix 2.11.7 改进

• Compile error with AIX. The AIX 6/7 resolver(5) API defines RES_USE_DNSSEC without defining the "ad" bit. Fixed by disabling DNSSEC support for AIX 7x and earlier.

• The xtext_unquote() function did not propagate error reports from xtext_unquote_append(), causing the decoder to return partial ouput, instead of rejecting malformed input. The Postfix SMTP server uses this function to parse input for the ENVID and ORCPT parameters, and for the XFORWARD and XCLIENT commands.

Postfix 3.0.3 改进：

• The COMPATIBILITY_README text and HTML files were not installed.

• The uxtext_unquote() function had the same problem as xtext_unquote(), because one was created by copying the other.  The Postfix SMTP server uses this function to parse input for the ORCPT parameter with SMTPUTF8.

• Unreported bug: Postfix smtpd_mumble_restrictions could report an incorrect reason for failed DNS lookups.  Fixed by saving and restoring h_errno while evaluating the result from multi-query DNS lookups.
