Webmail实现源理,有三种。1、使用POP、IMAP Socket实现,2、通过直接访问物理文件实现,3、使用语言的开发包API实现。





  1. 下载SquirrelMail,解包后复制到Apache目录下

    [root@linuxas3 src]# wget http://heanet.dl.sourceforge.net/sourceforge/squirrelmail/squirrelmail-1.5.0.tar.gz

    SquirrelMail attempts to set the language in many ways.  If it
    can not figure it out in another way, it will default to this
    language.  Please use the code for the desired language.

    Command >> 2
    This option is obsolate. Default charset depends on language
    you have selected in "Default language" option.

    special key 'all' - all languages available in SquirrelMail will be
    listed. If you enter special key 'none' - user won't be able to changelanguage and interface will use language set it "Default language" option.

    While we have been building SquirrelMail, we have discovered some
    preferences that work better with some servers that don't work so
    well with others.  If you select your IMAP server, this option will
    set some pre-defined settings for that server.
    Please note that you will still need to go through and make sure
    everything is correct.  This does not change everything.  There are
    only a few settings that this will change.
    Please select your IMAP server:
        cyrus      = Cyrus IMAP server
        uw         = University of Washington's IMAP server
        exchange   = Microsoft Exchange IMAP server
        courier    = Courier IMAP server
        macosx     = Mac OS X Mailserver
        mercury32  = Mercury/32
        quit       = Do not change anything
    Command >>
  15. 配置webmail虚拟主机

    <VirtualHost xxx.xxx.xxx.xxx>
        ServerAdmin webmaster@example.org
        DocumentRoot /var/www/html/squirrelmail
        ServerName webmail.example.org
        ErrorLog logs/SquirrelMail-error_log
        CustomLog logs/SquirrelMail-access_log common
    [root@linuxas3 squirrelmail]# service httpd restart
    Stopping httpd:                                            [  OK  ]
    Starting httpd:                                            [  OK  ]
