Sendmail smarthost
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:
Code:
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
