Hi 怀守昆,
A quick look at the MX records for cn.ibm.com shows the following: -
cn.ibm.com mail exchanger = 10 e23-mx1.au.ibm.com.
cn.ibm.com mail exchanger = 10 e23-mx2.au.ibm.com.
cn.ibm.com mail exchanger = 10 e23-mx3.au.ibm.com.
cn.ibm.com mail exchanger = 5 e28-mx1.in.ibm.com.
cn.ibm.com mail exchanger = 5 e28-mx2.in.ibm.com.
cn.ibm.com mail exchanger = 5 e28-mx3.in.ibm.com.
The IP address James used corresponds to one of three assigned to
e28-mx2.in.ibm.com
These addresses don't respond to pings but if I run the telnet command I
get the expected response: -
$ telnet 122.248.162.1 25
Trying 122.248.162.1...
Connected to 122.248.162.1.
Escape character is '^]'.

Perhaps you should try the same telnet command from your server to see
if you get the same. Port 25 is the standard port you would expect to
be used for email so I don't think they would be using another one. If
telnet doesn't work then it is likely a firewall is blocking your
attempt somewhere and you may have to perform a trace command to see
where the packets stop.

It seems james always try to connect SMTP server's port 25, can james
connect to other port?
