Relay Exchange Server 2003
Help:
My exchange server will not send out emails from a internal server. I have a applicataion that converts our invoices to a PDF and then send them using SMTP. THis was working but recently I updateed our firewall and now my exchange server is rejecting these emails. I have added the server IP address that is converting the invoices to a PDF in my exchange server to allow rellay from this IP address, but it is still rejecting these emails.
IE
Error: Sending to SMTP Server Failed: (48): Setting TO failed.
550 5.7.1 Unable to relay for penni@blue.edu
Invoice No 0905793 BLUE CLIFF CAREER COLLEGE
Error: Sending to SMTP Server Failed: (48): Setting TO failed.
550 5.7.1 Unable to relay for penni@blue.edu
I need a bit of direction, if someone can chime in and present outside point of view....
I this rejection becasue of the server the email is sending to or my exchange server.....?

What firewall are you using - when you say updated did you change rules for your Exchange?
What are the updates you did on the firewall ? are the two servers hosted in the same network subnet ?
This does not looks like an Exchange generated NDR.
Try to do a telnet from the IP address from where your application is submitting an email to the Exchange server on port 25.
try giving the following commands.
ehlo
mail from: test@test.com
rcpt to: <one of your external email address like yahoo adress or gmail address>
data
Subject: test
Test.
.
Check if the above commands is getting accepted by the Exchange server. - If it is accepted, your Exchange is fine.
If it is accepted, log on to your Exchange box and do a telnet to the MX record of the domain for which you are submitting the email to from your application.
Try following the same set of commands except that in the rcpt to: provide the email address to which the application sends emails to.
Check what is going on with it.

I have done this test and it works from every server.....Any other ideas?

PS I have a SonicWall firewall solution...
Could you track your messages being sent from the Application through your server and see what is the stage at which the message is getting an NDR? I am pretty sure that the server is not generating it, but could you confirm?

My server is hung...It seems that I am relaying emails and have worked today to stop them but I still find that I am comming up as a relaying email server.
I used DNSGoodies to test and the results are:
220 BIOMAIL.corp.biotone.com Microsoft ESMTP MAIL Service, Version: 6.0.3790.4675 ready at Thu, 8 Sep 2011 14:33:38 -0700

My solution fixed the problem.
How many Exchange servers you have?
How you delivery the emails to the Internet, do you use an equipment or are they delivery directly from the Exchange server?
