--with-quarantine-agent=PROG 默认情况是，在其内部用户隔离箱里DSPAM会自动隔离垃圾。要是您不想使用默认的方式，您就得指定您自
己的隔离代理。--with-delivery-agent选项也是同理。任何时候当某个邮件被认为是垃圾邮件时，隔离代
理将被调用。
--enable-broken-mta
要是您的MTA（报文传送代理）被破坏了，您就可以用此命令，用CTRL-M把邮件传到DSPAM中。
--enable-broken-return-codes
如果是垃圾邮件则使DSPAM返回99（退出码：exitcode），不是垃圾邮件则返回0，其他的返回值则表示有
错误发生。默认方式下不会考虑结果怎样，只要操作成功，就返回0。只有用这种方式您才能明白您在做什么。
--with-quarantine-agent=PROG
By default, DSPAM automatically quarantines spams in its internal
user quarantine box. If you wish to override this default behavior,
however, you may do so by specifying your own quarantine agent. The same
notes from the --with-delivery-agent option apply here. The quarantine agent
will be called whenever a message is believed to be spam, with the message
provided as stdin into the tool.
字串3
--enable-broken-mta
You should enable this if your MTA is broken and passes messages into DSPAM
with CTRL-M's (^M) in them.
--enable-broken-return-codes
Causes DSPAM to return an exit code of 99 if a message is spam, 0 if
innocent, and any other code if an error has occured. The default is to
return 0 whenever the operation is successful, regardless of outcome. Only
use this if you know what you're doing!
--with-storage-driver=DRIVER
指定一个可选择的存储驱动。这个驱动是特地为DSPAM来写存储记号，签名数据，以及其他的私有操作。
通常默认的驱动是libdb4_drv,可以和Berkeley DB v4结合。下面给出了一些驱动：
libdb4_drv: Berkeley DB4 Library
libdb3_drv: Berkeley DB3 Library
mysql_drv: MySQL Drivers
ora_drv: Oracle Drivers (BETA)
pgsql_drv: PostgreSQL Drivers (BETA)
您也许要用到某些特定的驱动来配置标记（以后讨论）。
--enable-client-compression
在用存储驱动之处（目前只有mysql_drv），使客户机数据源能够压缩。中导致数据源和其客户机的数据均被压缩。 字串1
如果您的数据源为了节约带宽而在一个与DSPAM代理分离的机器上时，您应该用此选项，但是这样会花费占
用一些CPU。
--disable-trusted-user-security
管理员们可以用此配置标识来使trusted user security 不可用。这样会使DSPAM对每一位用户都很“信任”，允许他们在服务器里通过DSPAM潜在执行任意的命令。
由此，管理员应该只用此于服务器关闭时，或是将其DSPAMbinary配置成只有可“信任”用户执行的形式。
这个选项绝对不应该用来当作解决MTA授权优先于调用DSPAM的办法。相反，请查看本文的TRUSTED SECURITY部分。
--with-storage-driver=DRIVER
Specify an alternative storage driver. A storage driver is a driver
written specifically for DSPAM to store tokens, signature data, and
perform other proprietary operations. The default driver is libdb4_drv,
which incorporates Berkeley DB v4. The following drivers have been provided:
libdb4_drv: Berkeley DB4 Library
libdb3_drv: Berkeley DB3 Library
mysql_drv: MySQL Drivers
ora_drv: Oracle Drivers (BETA)
pgsql_drv: PostgreSQL Drivers (BETA)
You may also need to use some of the driver-specific configure flags
字串7
(discussed later).
--enable-client-compression
Enables data source client compression for storage drivers where it is
available (presently only mysql_drv). This causes data between the
data source and its clients to be compressed. You should use this option
if your data source is on a separate machine from the DSPAM agent(s) as it
conserves bandwidth, but at the expense of a few CPU cycles.
--disable-trusted-user-security
Administrators who wish to disable trusted user security may do so by
using this configure flag. This will cause DSPAM to treat each user as
if they were "trusted" which could allow them to potentially execute
arbitrary commands on the server via DSPAM. Because of this, administrators
should only use this option on either a closed server, or configure their
DSPAM binary to be executable only by users who can be trusted. This
option SHOULD NOT be used as a solution to your MTA dropping privileges
prior to calling DSPAM. Instead, see the TRUSTED SECURITY section of this 字串9
document.
--enable-homedir-dotfiles
如果选择可用（enabled）,DSPAM将在用户的主目录里检查.nodspam|.dspam文件，而不是检查
$DSPAM_HOME/$USER/opt-in/ $USR[.nodspam |.dspam]。这两个dotfiles用来过滤opt-out或opt-in。
--enable-opt-in
使DSPAM为只有.dspam dotfile的文件过滤邮件。默认方式是opt-out,它需要一个有.nodspam 文件回避过滤。
--enable-homedir-dotfiles
When enabled, instead of checking for $DSPAM_HOME/$USER/opt-in/
$USER[.nodspam|.dspam], DSPAM will check for a .nodspam|.dspam file in the
user's home directory. These two dotfiles are used for opt-out or opt-in
filtering.
--enable-opt-in
Causes DSPAM to filter mail only for users with a .dspam dotfile. The
default is opt-out, which requires a .nodspam file to exist to bypass
filtering.
