I just finished setting up a Nagios server and configured it.  I installed Postfix and setup relaying to the exchange 07 box.  But I followed the instructions outlined in here http://msexchangeteam.com/archive/2006/12/28/432013.aspx
and I could not still send messages.  How do I forward messages from root on Postfix to a particular user on exchange?  What do I specify?

Can you tell us whether or not if the postfix queue is holding the email messages?
Is there any indication of errors or otherwise in the logs?

http://www.postfix.org/BASIC_CONFIGURATION_README.html#syslog_howto

Also, can you test using telnet?
telnet <ip of E2K7> 25
HELO 1234

does it connect to your Exchange server? Or is it blocked?

I do see them coming in the queue but seems like they dont really go anywhere
PS I can telnet into exchange just fine on port 25

add americanriskins.com to /etc/postfix/local-host-names and restart Postfix?

~~~

check your main.cf file...
Is your "smtpd_use_tls" set to "yes"? set it to "no" and save

" Whenever you make a change to the main.cf or master.cf file, execute the following command as root in order to refresh a running mail system:
    # postfix reload
"
http://www.postfix.org/BASIC_CONFIGURATION_README.html

~~~

When using the telnet test from your server, were you able to generate a test email to "cjameson@americanriskins.com"?

use the following to test...
telnet <ip> 25
helo 1234
mail from: cjameson@Monitor.DomainServer.net
rcpt to: cjameson@americanriskins.com
data
"test test test"
.
quit

~~~
in general, if you make a mistake on a line during telnet 25 test, don't use backspace to correct it; just start another line and try again

let us know

I do not have a file called  /etc/postfix/local-host-names
Is there another file I need to edit?

How do I send a message to a certain email address to an exchange server.  I know the sending part works fine from the Postfix end...but do I need to setup an alias from the root user? Or how does that work?  Basically I just want anything from the nagios alert box to send directly to my email address.

Ok I answered my own question ...
550 5.7.1 Unable to relay (in reply to RCPT TO command))

The thing is I setup custom connectors on my exchange server 07 already...not sure why they wouldnt be working.  Do I need to set this up on the default connnector?  We have like 3 or 4 of them.  I just dont want to open it all up (the default connector) and allow spam in thats all.  Any suggestions?

You would create a new connector and set it to relay only for your specified linux server.
