RedHat, Enterprise Linux, Version 5, External SMTP Sendmail Configuration
Hi !
We have a Redhat Linux Enterprise version 5.0 webserver hostname zzz at www.xxx123.com. We also have an email server mail1.xxx123.com located at a different location. We are running a PHP application which uses sendmail to send out email from a feedback page. Some email servers check the message header which states apache@zzz.xxx123.com. The foreign mail servers find that zzz.xxx123.com is not a vaild DNS name.
For reasons which I cannot explain here I cannot create a DNS entry for zzz.xxx123.com.
I would like the webserver to send out emails using the mail server mail1.xxx123.com so that message headers only bear the name mail1.xxx123.com
All help apreciated
Thanks

Hi mwcomputers
Will check with the developers. Was told that this can be set only in the PHP windows version and not the linux version

The link you sent also states that it is applicable only for Windows

Hi Fosiul01
The Mail server is a different server mail1. running a Windows OS with mdameon
The webserver is a Redhat Linux Enterprise server 5.0 which has the PHP application. Visitors to the site can submit a feedback form and the PHP app sends an auto-reply to them. When the visitors mail server receives the mail it shows as being received from the webserver whereas we want the header to show that the mail is coming from the mailserver.

ok , if your webserver and mailserver is in same network then you need to change sendmail.mc configuration to like this :
define(`SMART_HOST',`mail1
and MASQUERADE_AS(`mydomain.co
let me know what is outcomes from this
define(`SMART_HOST',`mail1
and MASQUERADE_AS(`mydomain.co
let me know what is outcomes from this
sorry you dont need this line
and MASQUERADE_AS(`mydomain.co
and MASQUERADE_AS(`mydomain.co

Hi fosiul01
I have tried that but i did not add the dnl at the end. I will try it with the dnl at the end. Does sendmail.cf need to be recompiled with the m4 command or can we just restart sendmail.
Secondly the two servers are not on the same LAN. In fact they are at different locations but both can be reached through a public IP

Thanks fosiul01.
I undertsand the problem fully but think there shoudl be a solution as this is possibel in a Windows environment as suggested bymwecomputers. I am not sure how to do it in Linux.

you mean, changing the return path is not it ??
i was doing some investigation
check the bollow code :
<?php
$message =" Hi";
$to="fosiul@yourdomain.com
$subject="return path";
mail($to,$subject,$message
?>
by using this simple code, you would be able to change the return path what ever you want
but chagne your /etc/hosts to zzz zzz.yourdomain.com
