Sendmail Help

[Anish Mathew <nedumannilanish yahoo co uk>]

Hi,
I want  to run sendmail as a client mail server.Is it
possible to do so..

The reason why i want to do this is we dont have a
public ip .. and for security reasons only one mail
server is allowed in each state, ours is a district
centre.

Well i tried these things
I edited the sendmail.mc file to add 

define('SMART_HOST','mail.myserver')

after that i can send mail from my local system.

is it the right way to do it.. anybody pls explain the
what's actually happening when a mail server is
started.. how it actually works .

well on more question...

i want to pull the mails received at my main mail
server to the client mail server also i want to do
this automatically.. is it possible? dose sendmail can
handle this..?

Thanks in adv 

Anish
