无法弹出配置向导，应该是对光驱的检测不对导致的。
进入你安装好的系统，看下光驱的设备名是什么，然后就可以有对应的方案。

DNS解析设置好了，可是好像还没有用耶！pop3&imap还是无法正常使用！
升级建议：
我的iRedMail安装的是 0.3.2，到目前的 0.4.1 也发生了很多变化，我也断断续续的手工升级过部份组件，如postfix，clamav等，觉得这不是比较好的方法，最好的方法还是应该用yum update 来对所有的组件进行升级，并提示更新每个组件的配置文件中的相关改变和加强参数进行补充说明。
很抱歉，我不赞同这个建议。
理由：
对roundcube的建议，希望对里面的功能保持一致的升级，如0.1.1中的“自动转发”和“自动回复”。对于主要的主题（addon ）也进行保持。不然，在生产环境中是不能贸然升级组件。
这个我们一直都会保证大家可以使用相同的功能的，放心好了。只有更好。
列在成功案例页面是鼓励大家以这种最简单的方式来帮助我们宣传和推广。
如果大家连这点简单的事情都不愿意，只有索取没有贡献，这个项目就无法良性循环。最终结果是迫使我放弃维护这个项目。
做出点东西之后大家自然会跟踪这个线索的，加油 :loveliness:
“让所有人都可以看到”是什么意思呀？全局地址簿？如果是的话，只有使用 LDAP 存储虚拟用户，就会自动在写地址的时候弹出下拉框。

protocols = imap imaps pop3 pop3s
listen=*
disable_plaintext_auth = no
ssl_disable = yes
mail_location = maildir:/var/spool/mail/%d/%n
auth default {
mechanisms = PLAIN LOGIN CRAM-MD5 DIGEST-MD5
passdb sql {
args = /etc/dovecot-mysql.conf
}
userdb sql {
args = /etc/dovecot-mysql.conf
}
socket listen {
client {
path = /var/run/dovecot/auth-client
mode = 0660
user = postfix
group = postfix
}
}
}

dovecot-mysql.conf 配置如下：
driver = mysql
connect = host=192.168.1.2 dbname=postfix user=root password=123456
default_pass_scheme = MD5
password_query = SELECT password FROM mailbox WHERE username = '%u'

iRedMail 里有 /etc/sysconfig/iptables 文件的。
cron 里的信息是说中国区镜像无法访问。但是它还是会自动搜索可用的镜像的。所以这个消息可以乎略掉。
最新的 clamav-0.95 有问题，在论坛里有回复了。搜索一下吧
邮箱很慢，到底系统哪里不正常？
看看 top 命令的输出，是否有什么异常进程，比如占用大量的 CPU/内存 资源。
看看网络流量是否正常。
不需要。:L
这份不是 iRedMail 官方的升级文档，请大家不要照着这份文档进行升级。
补丁是给 roundcube 0.1.1 的。
iRedMail-0.4.0 不需要。
iRedMail 是开源的，自行打包的软件也都有源码：
http://www.iredmail.org/yum/srpms/
你要的补丁也在里头
邮件列表里给了相关的链接的
Hi, all.
iredmailsupport@ 技术支持邮件列表中已经发布了用于修正 roundcube-0.1.1 的两个安全问题的补丁，请大家及时打上补丁以修正问题。

用哪个功能的时候慢？
看看系统的日志，是否有不正常情况。例如 apache 日志，dovecot 日志，邮件日志。
php 里的 mail 函数，是不是和使用系统上的 mail 命令是一样的效果？如果是的话，那就应该是被处理了两次了。
我对 PHP 不熟悉，所以帮不上忙，很抱歉。:L
不要用 php 的 mail 函数来发送，这个之前有网友测试过，有问题。
你用标准的 SMTP 验证的方式来发送试试。
