企业邮箱配置
<EmailAccount
                account="xx@xxx.com.cn"
                password="xxxxxxx"
                sendname=""
                useFullNameSignIn="0"
                
                protocol="imap"
                host="邮箱IP"
                port="143"
                
                protocol_send="smtp"
                host_send="邮箱IP"
                port_send="25"
                
                appendHTML="0"
        />
按此设置Live mail能收到，配置移到语盒上就出了上面的提示。
