    登入postfixadmin設定，參考之前寫的文章中，postfiadmin 設定的部分，主要就是修改 setup password

    [http://wp.cowbay.org/2016/01/27/%e7%ad%86%e8%a8%98-centos-6-6-iredmail-0-9-4-%e5%ae%89%e8%a3%9d%e7%ad%86%e8%a8%98/](http://wp.cowbay.org/2016/01/27/%e7%ad%86%e8%a8%98-centos-6-6-iredmail-0-9-4-%e5%ae%89%e8%a3%9d%e7%ad%86%e8%a8%98/)

    在完成設定後，會取得setup_password 的hash值，像是這樣
    <pre><span class="hljs-variable"><span lang="EN-US">$CONF</span></span>`<span lang="EN-US">[</span>`<span class="hljs-string"><span lang="EN-US">'setup_password'</span></span>`<span lang="EN-US">] = </span>`<span class="hljs-string"><span lang="EN-US">'fd16d423a537fa766a501d089823c8be:a23d10bad95c883c98c817ea37afaeae1d186624'</span></span>`<span lang="EN-US">;
    修改 config.inc.php 把得到的值替換掉原本的設定
    開啟 http://IP_ADDR/pfa/login.php
    用剛剛建立的管理者帳號、密碼登入，並新增網域、帳號 測試看看

UPDATE

要發信的時候會發生錯誤

要在 main.cf 裡補上這一行
&gt; mailbox_command = /usr/libexec/dovecot/deliver
這樣才可以

* * *

接下來要弄 RoundCubeMail  / Letsencrypt

yum install roundcubemail

修改安裝路徑的目錄擁有者和權限 (所以我說嘛，為啥一開始要把 httpd 的執行者改成 vmail ? )

開啟 roundcubemail 登入會發生錯誤

LOG裡面有提示

PHP Error: Access denied for new user  'auto_create_user' is disabled in /usr/share/roundcubemail/program/include/rcmail.php on line 622 (POST /roundcubemail/?_task=login?_task=login&amp;amp;_action=login)

打開這個選項就可以了！
