Trying to send nagios messages to my exchange

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?
I am running on Ubuntu

Also the telnet test worked
Took a few minutes but ya worked ok...

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.

Can anyone tell me why sending an email its never getting to the destination seems it goes nowhere

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.
