Oracle Relay mail server
Hi,

I have a postfix mail server on centos 6. (mailserver.mydomain.com )


I want to send mail through my mail server from other linux server ( server1 ), so that it will use mail server IP address.

I have tried.
Code:
myhostname = server1.mydomain.com 
relayhost = mailserver.mydomain.com

in client server ( say server1 ) postfix configuration. and restarted postfix.

but when i am sending mail form server1.

It is going but when i am checking full path of mail, it is showing
Code:
Received: from server1.mydomain.com

rather then
Code:
Received: from mailserver.mydomain.com

Can some one please let me know what is wrong in my configuration.


MY CONF on Client side.

Code:
queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
mail_owner = postfix
inet_interfaces = localhost
inet_protocols = all
mydestination = $myhostname, localhost.$mydomain, localhost
unknown_local_recipient_reject_code = 550
myhostname = server1.mydomain.com 
relayhost = mailserver.mydomain.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases


debug_peer_level = 2
debugger_command =
         PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
         ddd $daemon_directory/$process_name $process_id & sleep 5
sendmail_path = /usr/sbin/sendmail.postfix
newaliases_path = /usr/bin/newaliases.postfix
mailq_path = /usr/bin/mailq.postfix
setgid_group = postdrop
html_directory = no
manpage_directory = /usr/share/man

LEARN ABOUT NETBSD

mailer.conf

MAILER.CONF(5)						      BSD File Formats Manual						    MAILER.CONF(5)

NAME

     mailer.conf -- configuration file for mailwrapper(8)

DESCRIPTION

     The file /etc/mailer.conf contains a series of lines of the form

     name program [arguments ...]

     The first word of each line is the name of a program invoking mailwrapper(8).  (For example, on a typical system /usr/sbin/sendmail would be
     a symbolic link to mailwrapper(8), as would newaliases(1) and mailq(1).  Thus, name might be ``sendmail'' or ``newaliases'' etc.)

     The second word of each line is the name of the program to actually execute when the first name is invoked.

     The further arguments, if any, are passed to the program, followed by the arguments mailwrapper(8) was called with.

     The file may also contain comment lines, denoted by a '#' mark in the first column of any line.

     The default mailer is postfix(1), which will also start by default (unless specifically disabled via an rc.conf(5) setting) so that locally
     generated mail can be delivered, if the ``sendmail'' setting in /etc/mailer.conf is set to ``/usr/libexec/postfix/sendmail''.

FILES

     /etc/mailer.conf

EXAMPLES

     This example shows how to set up mailer.conf to invoke the postfix(1) program:

	   sendmail	   /usr/libexec/postfix/sendmail
	   mailq	   /usr/libexec/postfix/sendmail
	   newaliases	   /usr/libexec/postfix/sendmail

     This example shows the use of the mini-sendmail package from pkgsrc in place of postfix(1):

	   # Send outgoing mail to a smart relay using mini-sendmail
	   sendmail	   /usr/pkg/sbin/mini-sendmail -srelayhost
	   send-mail	   /usr/pkg/sbin/mini-sendmail -srelayhost

     Note the use of additional arguments.

SEE ALSO

     mail(1), mailq(1), newaliases(1), postfix(1), mailwrapper(8)

     pkgsrc/mail/sendmail, pkgsrc/mail/mini_sendmail

HISTORY

     mailer.conf appeared in NetBSD 1.4.

AUTHORS

     Perry E. Metzger <perry@piermont.com>

BUGS

     The entire reason this program exists is a crock.	Instead, a command for how to submit mail should be standardized, and all the ``behave
     differently if invoked with a different name'' behavior of things like mailq(1) should go away.
