Note to Chinese Users

Our domain name iredmail.org has been blocked in mainland China for years (since Jun 04, 2011), please run command below to finish the installation:

IREDMAIL_MIRROR='http://42.159.241.31' bash iRedMail.sh

Additional variables are:

• EPEL repo: IREDMAIL_EPEL_MIRROR='http://mirrors.aliyun.com/epel'

• SOGo repo: SOGO_PKG_MIRROR='http://42.159.241.31/SOGo'

经过苦苦寻觅，解决方法为：

编辑 vi /etc/yum.repos.d/iRedMail.repo 文件，将org改为com,如下

[root@mx iRedMail-0.9.4]# vi /etc/yum.repos.d/iRedMail.repo 
[iRedMail]
name=iRedMail
baseurl=http://iredmail.com/yum/rpms/6/
enabled=1
gpgcheck=0
#exclude=postfix*
exclude=postfix*

baseurl=  改为 baseurl=http://iredmail.com/yum/rpms/6/
