problems sending mail() with php

I have a SuSE Server with a domain.ro and some subdomains.domain.ro
When I use function mail() to send emails from my domain and subdomains the From : looks like

From : www daemon apache <[email protected]>
From : www daemon apache <[email protected]>

Does anyone now what changes to make to have only email address in header(I don't want to use from header in php script).
Thanks

 

not from php script

I dont want to use php script .

 

maybe I was not very clear

I dont want to use From : in my php script
I put in php.ini sendmail_path = /usr/sbin/sendmail -t -i [email protected]
Or in main.conf in postfix i made a
sender_canonical_maps = hash:/etc/postfix/sender_canonical
In sender_canonical i put
[email protected] [email protected]

The result is the same the from looks like
From : www daemon apache <[email protected]>
I dont want to see www daemon apache only <[email protected]>

 

solved

I solved my problem.Now default (without from in php script) from server configuration
From : [email protected] for my domain
From : [email protected] for my subdomains

Thanks anyway
