[OT] automatic mail bash script

hi all,
I have a problem...I need that my postfix send me ( on gmail account ) an
email after the server started up. Can I use the same account on gmail to
send it?
I've tryed with

mail -s test [email protected] < mail_text

the cat of mail_text is

test test test
.

but the answer is: Mail Delivery Status Report will be mailed to <root>

Could anybody help me? What really i need to change in main.cf?

thanks a lot
