问 :
Some of my vendor in mainland china sent email to me but failed, pls check the reason.

答 :
About xxx" <xxx@xxx.com.cn> can not receive vendor's email

I have check your email system and have information as below

1 now Shenzhen office is still using Exchange Email server in HongKong (server name xxx--192.168.101.10)

2 xxx.com.cn email receiver address(MX mail.xxx.com.cn) have been change from Beijing to Germany ip address 193.xxx.xxx.xxx, this is email server of German office which running Postfix emailserver software

3 when people in Shenzhen office sending email to outside , that email send as below Shenzhen office pc -> Hongkong Email server -> Germany office email server -> outside address

4 when outside people send email to xxx.com.cn, as below outside -> Germany office email server -> Hongkong email server -> Shenzhen office pc

So as description above , outside people send email to xxx.com.cn will first goto Germany email server, then forward to Hongkong server then people receive email from hongkong server, because China <-> Germany internet speed if not same fast and stable as send between china's two address, sometime maybe internet connection between China and Germany have problem for a short time cause email fail send to Germany.

Another reason maybe because Germany server have some problem cause that server can not receive email , Because China and Germany is not same time, Maybe vender in china send email to germany is not working time in Germany, So if this not work time Germany email server have problem,nobody know and nobody fix that problem, cause email send to xxx.com.cn at that time period will not deliver successfully.

People in Shenzhen will continue to see if that problem happen again, espically when people send some big email to check how long to take to got that big email or if  that email just can not received.

Hontonet can provide solution of that email system, We make 2 or more Mx email server put in different ISP make email server load banlance and high availability, If one emailserver'shardware or internet connection have problem. email still can work normally. Client can see exchange or other email server and do not need static internet ip address(In china static internet ip address is about 10-20 time fee as dynamic ip address such as adsl).

问：
今天早上发现我的服务器无法发信给xxx.com,我看了好像昨天就有问题了，现在在我的服务器上堆积了很多发给xxx.com的邮件。

回答：
这个是对方邮件系统的域名。应该是对方的邮件服务器出问题了，上次我记得我这边发现很多xxx.com发到服务器的病毒邮件。

问：
我公司一经理的邮件账号有问题，现在用WEBMAIL不能进入，请帮我查查，急。谢谢。
账号：XXX
密码：XXX

回答：
有时候会有某些邮件主题有怪字符导致webmail无法显示，这时候用outlook把服务器上邮件收下就可以了，或者在设置webmail语言的时候都设置为英文也可以避免这个现象。我改变了XXX webmail中的设定为英语现在可以进入了。
