构建反病毒反垃圾邮件系统(八)

  把用户添加到邮件列表里测试一些,建一个文本文件,比如members.txt,一行一个邮件地址,然后执行如下命令就可以了:


  # /usr/local/mailman/bin/add_members -n members.txt mailman


  3、postfix相关配置


  还需要修改postfix的配置文件才能使mailman工作正常,修改main.cf,加上:


  owner_request_special = no
  recipient_delimiter = +
  unknown_local_recipient_reject_code = 550


  修改alias_maps和virtual_maps为:


  alias_maps = hash:/usr/local/mailman/data/aliases,
  mysql:/etc/postfix/mysql-aliases.cf
  virtual_maps = hash:/usr/local/mailman/data/virtual-mailman,
  mysql:/etc/postfix/mysql-virtual.cf


  单单这样还是不行的,我测试还需要把main.cf里myorigin改为:


  myorigin = lists.test.org


  然后在transport表里添加一个记录:


  insert into transport set domain=’lists.test.org’,destination=’local:’;


  重启postfix和mailman,现在可以试试给mailman这个邮件列表发邮件是否都正常了?


  4、python处理中文的问题


  如果邮件都是中文gb2312编码的就有问题,查看/usr/local/mailman/logs/error会发现如下的错误:


  Jul 16 17:40:09 2003 (392) Uncaught runner exception: unknown encoding

  这是由于python不支持gb2312的缘故!在linuxforum找到一篇关于如何使python支持gb2312的文章:

  我就用了作者提供的http://bbs1.nju.edu.cn/file/gb2312.rar,其实它也是从http://sourceforge.net/projects/python-codecs/来的。把gb2312目录的gb2312.py文件拷贝到/usr/lib/python2.1/encodings/目录下,chinesecn目录也拷贝到该目录下,然后修改/usr/lib/python2.1/encodings/aliases.py文件,在最后的}前加上:


  # gb2321_cn codec
  ’gb2312′: ‘gb2312’,
