前几天自己的电脑老是出一个提示，后来看一篇介绍弄好了。现在把解决方法弄出来供大家参看。

FreeBSD邮件服务Postfix问题：“fatal: open database /etc/aliases.db”

FreeBSD邮件服务Postfix问题："fatal: open database /etc/aliases.db"

E: What does "fatal: open database /etc/aliases.db" mean?
C: "fatal: open database /etc/aliases.db" 意味着什么？

E: DB files are maintained by the Berkeley DB library. The above
message means one of the following things:
C: DB数据库文件由Berkeley DB链接库维护。以上的消息意味着以下的几种情况之一：
E: * The existing file does not have the expected file format. The
cause is one of the following:
C: 已存在的文件没有期望的文件格式。原因为以下情况之一：
E: o The file was created by Berkeley DB version 1 and you
are using version 2 or 3 (or vice versa).
C: 此文件由Berkeley DB版本1所创建，而你正在使用版本2或3（反之亦然）。
E: o The file was written in "btree" format and Postfix
expects "hash" format (or vice versa).
C: 文件以"btree"格式写就，而Postfix需要"hash"格式（反之亦然）。
E: To fix the problem for Postfix execute the following command as root:
C: 欲为Postfix修正此问题，以root用户运行以下命令：
newaliases
E: This creates the aliases.db in the format that Postfix expects.
C: 这将以Postfix所期望的格式创建aliases.db。

E: * Or the problem could be something completely different. If
the result of running newaliases is a zero-length aliases.db file,
then you probably suffer from the following problem.
C: 或许问题恰好完全相反。如果运行newaliases的结果是一个空aliases.db文件，那么你可能遇到的是以下的问题。
E: o Postfix was compiled with #include files for Berkeley
DB version X and was linked against object library files for Berkeley
DB version Y, where X and Y are different versions of the Berkeley DB
library.
C: Postfix编译时包含了Berkeley DB版本X的文件，而为Berkeley
DB版本Y链接为目标库文件，而X与Y为Berkeley DB的不同版本。
E: The fix for this is to properly install the Berkeley DB
library. For example, RedHat version 7.0 uses the Berkeley DB version
3 object library by default, but no /usr/include/db.h file is
installed by default. In order to correctly build Postfix you must
install the db3-devel package.
C: 解决此问题的方法是适当的安装Berkeley DB库。例如，Redhat版本7.0默认使用了Berkeley DB
版本3的目标库，却没有默认安装/usr/include/db.h文件。为了正确的建立Postfix，你必须安装db3-devel文件包。
E: On a properly installed system, including the file <db.h> and
linking with -ldb should access files from the same Berkeley DB
library version.
C: 在一个适当安装好的系统中，包含文件<db.h>并且链接以-ldb选项将会利用Berkeley DB相同版本的库文件。

用着那么烦?
# cd /usr/local/etc/postfix
# postalias aliases
再把main.cf里的修改一下就OK.
alias_maps = hash:/usr/local/etc/postfix/aliases

这是从那边翻译过来的。其实也只是一个命令
