步骤2：数据存储升级
如果您用的是基于SQL的驱动程序，只需作很小的改动即可。这些改变只对基于SQL的驱动程序是必要
的；如果您用的是BerkeleyDB存储驱动则无须作改动。
下面的SQL代码应该更新MySQL和Oracle数据库的3.0版格式。确定用DSPAM进入schema以便能运用这些改动。
alter table dspam_stats add spam_learned int;
alter table dspam_stats add innocent_learned int;
alter table dspam_stats add spam_classified int;
alter table dspam_stats add innocent_classified int;
update dspam_stats set spam_learned = total_spam;
update dspam_stats set innocent_learned = total_innocent;
update dspam_stats set spam_classified = 0, innocent_classified = 0;
alter table dspam_stats drop column total_spam;
alter table dspam_stats drop column total_innocent;
alter table dspam_stats add spam_misclassified int;
alter table dspam_stats add innocent_misclassified int;
update dspam_stats set spam_misclassified = spam_misses;
update dspam_stats set innocent_misclassified = false_positives;
alter table dspam_stats drop column spam_misses;
字串7
alter table dspam_stats drop column false_positives;
步骤3：编译DSPAM V3.0
DSPAM v3.0改动了很多命令行的特征。其他的configure-time参数也有所改动或删除。下面列举了对
configure-timed做的变动：
--with-userdir-* changed 'userdir' to 'dspam-home'
--with-local-delivery-agent changed to --with-delivery-agent
--enable/disable-chained-tokens removed from configure
--enable/disable-bnr removed from configure
--enable/disable-whitelist removed from configure
--enable/disable-toe removed from configure
--enable/disable-tum removed from configure
--enable/disable-spam-delivery removed from configure
--enable/disable-deliver-fp removed from configure
一旦您配置了DSPAM，运行：make && make install
进行编译安装软件。
注：默认的DSPAM路径由changed from /etc/mail/dspam 变为 /var/dspam.如果您想用老的路径，
请用 --with-dspam-home=/etc/mail/dspam 指定。
1.1 INSTALLATION
UPGRADING
------------------------------------------------------
字串2
IMPORTANT UPGRADE STEPS FOR USERS UPGRADING FROM <3 /> ------------------------------------------------------
Version 3.0 incorporates many changes to the user interface, but preserves
the general data structure so that users don't need to re-train in order
to upgrade.
Step 1: Shut down the existing DSPAM installation.
The existing DSPAM installation should be shut down prior to any upgrade
changes. The easiest way to do this is to turn off the MTA and web
server serving the DSPAM CGI. No mail should be processed while the
changes are being made.
Step 2: Data Storage Changes
If you are using a SQL-Based driver, a few minor changes will need to
be made. These changes are only necessary to SQL-Based drivers; no
changes need to be made if you are using the BerkeleyDB storage drivers.
The following SQL code should upgrade both MySQL and Oracle databases to
the v3.0 format. Be sure to log into the schema used by DSPAM to apply
these changes.

alter table dspam_stats add spam_learned int;
alter table dspam_stats add innocent_learned int;
alter table dspam_stats add spam_classified int;
alter table dspam_stats add innocent_classified int;
update dspam_stats set spam_learned = total_spam;
update dspam_stats set innocent_learned = total_innocent;
update dspam_stats set spam_classified = 0, innocent_classified = 0;
alter table dspam_stats drop column total_spam;
alter table dspam_stats drop column total_innocent;
alter table dspam_stats add spam_misclassified int;
alter table dspam_stats add innocent_misclassified int;
update dspam_stats set spam_misclassified = spam_misses;
update dspam_stats set innocent_misclassified = false_positives;
alter table dspam_stats drop column spam_misses;
alter table dspam_stats drop column false_positives;
Step 3: Compile DSPAM v3.0
DSPAM v3.0 has moved many features out to the commandline. Other
configure-time arguments have also been changed or removed. The following 字串3
is a list of configure-time changes that have been made:
--with-userdir-* changed 'userdir' to 'dspam-home'
--with-local-delivery-agent changed to --with-delivery-agent
--enable/disable-chained-tokens removed from configure
--enable/disable-bnr removed from configure
--enable/disable-whitelist removed from configure
--enable/disable-toe removed from configure
--enable/disable-tum removed from configure
--enable/disable-spam-delivery removed from configure
--enable/disable-deliver-fp removed from configure
once you have configured DSPAM, run: make && make install
to build and install the software.
NOTE: The default DSPAM home has been changed from /etc/mail/dspam to
/var/dspam. If you would like to use the old path, specify it using
--with-dspam-home=/etc/mail/dspam.
步骤4：更新CGI
DSPAM CGI必须得更新。许多的调用参数已经被改变了。
步骤5：重行配置MTA
DSPAM的命令行参数已被重写。您应该为所有新的命令行成分的圆满解释，考虑'AGENT COMMANDLINE
