[plug] Mail help

[Joong Cho]

Hello,

Whenever I said a mail to webmaster at startreklibrary.com, I get the following 
error message:

<webmaster at startreklibrary.com>: Host or domain name not found. Name service 
error for name=joongcho.com type=A: Host found but no data record of 
requested type

How do I prevent this type of message from occuring or what do I need to do 
in order to prevent this message?

Also, whenever I send mail to info at joongcho.com or info at startreklibrary.com, 
I get the following postfix message.

< info at joongcho.com > : unknown user: "info"

How do I add user's in postfix?

Thanks and have a Merry Xmas and New Year's everyone.
