about mail server

[Jessica Chou]

please help!
At what kind of situation that some certain mail servers can not receive mails from my mail server?
When I sent mails out, no matter if I sent it through a client-side email software(SMTP) or directly telnet to my email server to sent it with "sendmail", I couldn't get it.
First, I got warning message as:

Warning: message still undelivered after 4 hours
Will keep trying until message is 3 days old

after few more warning emails being sent to me, I got the "Returned mail: Cannot send message within 3 days" which contained:

But I can receive mails from "pchome" or "ethome".

Any configuration I need to check?
Thank you very much for your help.

My best suggestion is that you install and use the Webmin package. It's a web based administration utility that handles sendmail and many other system functions. It usually has enough dignostics to determine how things are currently configured and provides most of the necessary fill-in boxes to make it run correctly. Many unix flavors are supported but Linux is particularly well supported. I'm not a sendamil expert, but webmin has come to my rescue to perform the configurations that are usually needed.
