postfix之maildrop详解

maildrop

    安装：
        0.安装依赖库、头文件、库文件
             # ln -sv /usr/local/courier-authlib/bin/courierauthconfig   /usr/bin
             # ln -sv /usr/local/courier-authlib/include/*   /usr/include
             # yum -y install pcre-devel

        1.添加vmail用户和组，id大于1000：
             # groupadd -g 1001 vmail
             # useradd -g vmail -u 1001 -M -s /sbin/nologin vmail

        2.编译安装：
             # tar xf maildrop-xxx.tar.bz2
             # cd maildrop-xxx
             # ./configure \
                 --enable-sendmail=/usr/sbin/sendmail \
                 --enable-trusted-users='root vmail' \
                 --enable-syslog=1 --enable-maildirquota \
                 --enable-maildrop-uid=1001 \
                 --enable-maildrop-gid=1001 \
                 --with-trashquota --with-dirsync
             # make
             # make install

            编译选项详解：
                --enable-sendmail=/usr/sbin/sendmail
                --enable-trusted-users='root vmail' 启用信任用户为root和vmail
                --enable-syslog=1 启用日志
                --enable-maildirquota  启用邮件地址队列
                --enable-maildrop-uid=1001 启用maildrop的组id，即vmail
                --enable-maildrop-gid=1001 启用maildrop的用户id，即vmail
                --with-trashquota 启动传输队列
                --with-dirsync 启动目录同步


        3.检查安装结果，请确保有"Courier Authentication Library extension enabled."一句出现：
            # maildrop -v
            maildrop 2.6.0 Copyright 1998-2005 Double Precision, Inc.
            GDBM/DB extensions enabled.
            Courier Authentication Library extension enabled.
            Maildir quota extension are now always enabled.

        配置文件：
            /etc/maildroprc

             # vim /etc/maildroprc
                logfile "/var/log/maildrop.log" 指定日志文件

             # touch /var/log/maildrop.log
             # chown vmail.vmail /var/log/maildrop.log

    配置Postfix支持maildrop
        1.编辑master.cf
            # vim /etc/postfix/master.cf
                maildrop  unix  -       n       n       -       -       pipe
                    flags=DRhu user=vmail argv=/usr/local/bin/maildrop -d ${recipient}

            注意：定义transport的时候，即如上两行中的第二行，其参数行必须以空格开头，否则会出错。
     

        2.编辑main.cf，将投递代理由vitrual改为maildrop
             #vim /etc/postfix/main.cf
                virtual_transport = maildrop
                virtual_uid_maps = static:1001
                virtual_gid_maps = static:1001


        3.编辑/etc/authmysqlrc，更改mysql连接的用户
            #vim /etc/authmysqrc
                MYSQL_UID_FIELD  '1001'
                MYSQL_GID_FIELD  '1001'

            注意：没有此处的修改，maildrop可能会报告 “signal 0x06”的错误报告。

    配置extman和extmail支持maildrop：
        1.编辑/etc/httpd/httpd.conf，修改extmail和extman的用户身份。推荐第一种
            #vim /etc/httpd/extra/httpd-vhosts.conf
                SuexecUserGroup vmail vmail

            或：

            #vim/etc/httpd/httpd.conf
                User vmail
                Group vmail



        2.将用户邮件所在的目录/var/mailbox和extman的临时目录/tmp/extman的属主和属组指定为vmail
            #chown -R vmail.vmail /var/mailbox
            #chown -R vmail.vmail /tmp/extman

        3.修改extman的主配置文件中的默认用户ID和组ID，确保其为类似如下内容
            #vim /var/www/extsuite/extman/webman.cf
                SYS_DEFAULT_UID = 1001
                SYS_DEFAULT_GID = 1001

        4.验正配置：
            接下来重新启动postfix和apache，进行发信测试后，如果日志中的记录类同以下项，则安装成功
