Sendmail smarthost

[BL4CKFIRE64]

Hi, I have two servers, one of them is my web server, and one of them is my mail server. On my web server I have php scripts that are looking at my php.ini and calling on sendmail with /usr/sbin/sendmail -t -i

I want sendmail to relay the mail to my mail server where it will do the actual sending, instead of trying to send the mail itself from my web server. I have already tried this tutorial Smarthost and it appears to be ignoring my additions to the config file or syntax is wrong. I am running postfix on my mail server box if this makes any difference.

Also right now my mail is working sending from my web server although I don't want it to and it's sending this information in the email headers Received: (from www-data@localhost). Is there any way I can remove this since it's giving away the username my webserver is running under?

I did the same kind of stuff with sendmail few months before,

This is good link
Quick HOWTO : Ch21 : Configuring Linux Mail Servers - Linux Home Networking

And this is how i did:

Mail sent from Local Linux machine to Remote Linux
Mail Server which will sent the mails to outside world.


Local Linux machine:10.232.13.99
Remote Linux Server machine:12.167.43.117

Things done at remote machine (12.167.43.117)
==============================================
1)First login to that destination machine as root.
ssh root@12.167.43.117

2)Then go to mail directory.
#cd /etc/mail

3)change access file -(Access file -- controls which hosts are allowed to use sendmail)
#vi /etc/mail/access
connect:12.167	RELAY

4)type make command,
#make

5)open sendmail.mc file and make sure following line is commented.Only then sendmail will listen for connections from other machines on port 25.
dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

6)creat new configuration file using following command,
#m4 sendmail.mc > sendmail.cf

7)Restart the sendmail program.
#service sendmail restart

Things done at local machine (10.232.13.99) 
==========================================

1) Make sure local sendmail port 25 is not blocked  & Add ip address of remote machine in /etc/hosts file
#vi /etc/hosts
12.167.43.117   xxxcomdev.xxx.com       xxxcomdev

2) In sendmail.mc provide your sendmail server name and make sure DAEMON_OPTIONS is commented,

#vi /etc/mail/sendmail.mc

define(`SMART_HOST',`xxxcomdev.xxx.com') 

dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

3)creat new configuration file using following command,
#m4 sendmail.mc > sendmail.cf

4)Restart the sendmail program.
#service sendmail restart
