[Mailman-Users] How to config sendmail on FC5

[Daniel.Li]

Dear Hand,
Thanks in advance.
But i'm afraid that I still have some questions about this. Well, I
don't have much experience on this, any help on this is really
appreciated. :)

Yes, It works with a simple MUA.

Yes. I understand this part. And I have added.

Well, I didn't know much about this. Maybe it's difficult for me to
understand right away. But my case is as below:
a) I have set up server in local network (192.168.58.*). 
b) My router will dial (PPPoE) to the internet, and get a internet IP. 
c) All ports is pointed to my server on the router. 
d) So palfocus.oicp.net is diverted from Peanut server and jump to my
router's IP address, which is loging though DDNS method.

I have found this line in configuration.
But it can't work, see bleow.
