postfix之maildrop詳解

maildrop

    安裝：
        0.安裝依賴庫、頭文件、庫文件
             # 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用戶和組，id大於1000：
             # groupadd -g 1001 vmail
             # useradd -g vmail -u 1001 -M -s /sbin/nologin vmail

        2.編譯安裝：
             # 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

            編譯選項詳解：
                --enable-sendmail=/usr/sbin/sendmail
                --enable-trusted-users='root vmail' 啓用信任用戶爲root和vmail
                --enable-syslog=1 啓用日誌
                --enable-maildirquota  啓用郵件地址隊列
                --enable-maildrop-uid=1001 啓用maildrop的組id，即vmail
                --enable-maildrop-gid=1001 啓用maildrop的用戶id，即vmail
                --with-trashquota 啓動傳輸隊列
                --with-dirsync 啓動目錄同步


        3.檢查安裝結果，請確保有"Courier Authentication Library extension enabled."一句出現：
            # 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" 指定日誌文件

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

    配置Postfix支持maildrop
        1.編輯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：定義transport的時候，即如上兩行中的第二行，其參數行必須以空格開頭，否則會出錯。
     

        2.編輯main.cf，將投遞代理由vitrual改爲maildrop
             #vim /etc/postfix/main.cf
                virtual_transport = maildrop
                virtual_uid_maps = static:1001
                virtual_gid_maps = static:1001


        3.編輯/etc/authmysqlrc，更改mysql連接的用戶
            #vim /etc/authmysqrc
                MYSQL_UID_FIELD  '1001'
                MYSQL_GID_FIELD  '1001'

            注意：沒有此處的修改，maildrop可能會報告 “signal 0x06”的錯誤報告。

    配置extman和extmail支持maildrop：
        1.編輯/etc/httpd/httpd.conf，修改extmail和extman的用戶身份。推薦第一種
            #vim /etc/httpd/extra/httpd-vhosts.conf
                SuexecUserGroup vmail vmail

            或：

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



        2.將用戶郵件所在的目錄/var/mailbox和extman的臨時目錄/tmp/extman的屬主和屬組指定爲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認用戶ID和組ID，確保其爲類似如下內容
            #vim /var/www/extsuite/extman/webman.cf
                SYS_DEFAULT_UID = 1001
                SYS_DEFAULT_GID = 1001

        4.驗正配置：
            接下來重新啓動postfix和apache，進行發信測試後，如果日誌中的記錄類同以下項，則安裝成功
