ubuntu-qmail安装配置详解（step by step)(4)

邮件已经可以正常收发了，我们再接再厉，安装反垃圾邮件系统和杀毒系统

1、安装反垃圾邮件系统

root@ubuntu-sdp:/usr/tmp#cpan

cpan[1]>install Mail::SpamAssassin

最后会提示错误，因为有些模块没有安装

再依次安装

REQUIRED module missing: Net::DNS
REQUIRED module missing: NetAddr::IP
optional module missing: Digest::SHA1
optional module missing: Mail::SPF
optional module missing: IP::Country
optional module missing: Razor2
optional module missing: Net::Ident
optional module missing: IO::Socket::INET6
optional module missing: IO::Socket::SSL
optional module missing: Mail::DKIM
optional module missing: Encode::Detect

warning: some functionality may not be available,
please read the above report before continuing!

在以下安装过程，所有问题一律回车

cpan[2]>install Net::DNS

cpan[4]> install NetAddr::IP

cpan[1]> install Digest::SHA

 

cpan[2]> install Mail::SPF

cpan[3]> install IP::Country

cpan[4]> install Razor2

cpan[5]> install Net::Ident

cpan[5]> install IO::Socket::INET6

cpan[8]> install IO::Socket::SSL

cpan[8]> install Mail::DKIM

cpan[8]> install Encode::Detect

What email address or URL should be used in the suspected-spam report
text for users who want more information on your filter installation?
(In particular, ISPs should change this to a local Postmaster contact)
default text: [the administrator of that system]

NOTE: settings for "make test" are now controlled using "t/config.dist".
See that file if you wish to customise what tests are run, and how.

checking module dependencies and their versions...

***************************************************************************
NOTE: the optional Razor2 module is not installed,
minimum required version is 2.61.

  Used to check message signatures against Vipul's Razor collaborative
  filtering network. Razor has a large number of dependencies on CPAN
  modules. Feel free to skip installing it, if this makes you nervous;
  SpamAssassin will still work well without it.

  More info on installing and using Razor can be found
  at http://wiki.apache.org/spamassassin/InstallingRazor .

***************************************************************************
NOTE: the optional Net::Ident module is not installed.

  If you plan to use the --auth-ident option to spamd, you will need
  to install this module.

***************************************************************************
NOTE: the optional IO::Socket::SSL module is not installed.

  If you wish to use SSL encryption to communicate between spamc and
  spamd (the --ssl option to spamd), you need to install this
  module. (You will need the OpenSSL libraries and use the
  ENABLE_SSL="yes" argument to Makefile.PL to build and run an SSL
  compatibile spamc.)

***************************************************************************
NOTE: the optional Mail::DKIM module is not installed,
minimum required version is 0.31, recommended version is 0.37 or higher.

  If this module is installed and the DKIM plugin is enabled,
  SpamAssassin will perform DKIM signature verification when DKIM-Signature
  header fields are present in the message headers, and check ADSP rules
  (e.g. anti-phishing) when a mail message does not contain a valid author
  domain signature. Version 0.37 or later is needed to fully support ADSP.

optional module missing: Razor2
optional module missing: Net::Ident
optional module missing: IO::Socket::SSL
optional module missing: Mail::DKIM

warning: some functionality may not be available,
please read the above report before continuing!

Checking if your kit is complete...
Looks good
Warning: prerequisite Mail::DKIM 0.31 not found.
Writing Makefile for Mail::SpamAssassin
Makefile written by ExtUtils::MakeMaker 6.42

root@ubuntu-sdp:/usr/tmp/Mail-SpamAssassin-3.3.0#make

root@ubuntu-sdp:/usr/tmp/Mail-SpamAssassin-3.3.0#make install

root@ubuntu-sdp:/usr/local/bin#cd /usr/local/bin

root@ubuntu-sdp:/usr/local/bin# sa-update

root@ubuntu-sdp:/usr/local/bin# nano /etc/init.d/spamd

  GNU nano 2.0.9                          File: /etc/init.d/spamd                                                           

#!/bin/sh
/usr/local/bin/spamd &

然后将/etc/init.d/spamd加入自启动名单中（使用rcconf，这一步不详述了）

可以先手工运行

root@ubuntu-sdp:/usr/local/bin# spamd &

 安装程序需要damontools中的setuidgid这个程序，因为我们的damontools是手工安装的，所以拷贝这个东东过来
root@ubuntu-sdp:/usr/bin# cp /var/daemontool/command/setuidgid /usr/bin/setuidgid

root@ubuntu-sdp:/usr/bin# cd /usr/tmp/qmail-scanner-2.08加到/etc/enviroment

先手工增加，最好把这个/usr/local/clamav/bin加到/etc/environment中的PATH

Finished installation of initial directory structure for Qmail-Scanner
under /var/spool/qscan and qmail-scanner-queue.pl under /var/qmail/bin.

Finished. Please read README(.html) and then go over the script
(/var/qmail/bin/qmail-scanner-queue.pl) to check paths/etc.

"/var/qmail/bin/qmail-scanner-queue.pl -r" should return some well-known virus
definitions to show that the internal perlscanner component is working.

That's it!
