send email from local mail server to my gmail account

Thanks for the reply.
If I understand what you suggest, this configuration will send the mail from my gmail account...

This is not what I wanted.
I want to send the email from codeigniter via a local mail server (this is a link to it: http://www.toolheap.com/)
And I want the mail to be sent to a gmail account.
I'll fill the "To" field and "From" field in the code with $this->email->from() and $this->email->to().

I thought I can fill any email in the "From" field (I don't care if google will send this mail to the spam folder)

Thanks.
