Modifying the main.cf file

[LostinIT]

O.K. I believe this is about as basic a question as they get...

I am brand spanking new to Linux and have set up a test server to mave all my mail hosting services from Exchange 2000 to a Linux based network.
I downloaded and installed Postfix (current stable release) via yum with no problems. Now I get into configuring basic parameters.

My Question:

When modifying the main.cf file to my parameters, do I remove the pound '#' sign before that parameter?
Example:

The main.cf default values for the 'Sending Mail' parameter are as follows:

#myorigin = $myhostname
#myorigin = $mydomainname

Since only 1 can be set, would I use the following and remove the '#' sign from the beginning:

#myorigin = $myhostname
myorigin = $mydomainname

My gratitude ahead of time...

The # is a comment sign; if you remove it you change the line from an ignored comment to a live parameter.

You can of course edit the file to suit your installation - add and delete lines, change values, reorder lines, etc. The parameters are described in the Postfix manual.
