Exchange 2007 Receive and send mail from a program on local pc

Hello,

The client uses Outlook 2007 and Exchange 07. They have a custom program on their desktop that sends mail to many people, many local and many outside. It quit working when the server was replaced. The program says it uses port 25. Do I simply need to enable pop3 on exchange? Or do I need to make receive connectors? The program has an option to authenticate but it doesnt not work with her AD info so I am unssure if thats needed or not. Thanks

The program require 25 port - is SMTP service.
If your SMTP service on Exchange requires authentication - setup auth. parameters in your custom "mass mailer" software, for example: username and password for your e-mail account in AD.

I tried that earlier, and it starts making the list then says either "unable to communicate" or invalid username / password. The software is on the same lan as the exchange server.

Make sure that the SMTP Service is enabled on the Exchange
Test the Exchange SMTP by doing a telnet from another machin
telnet exchange.ip 25
if you get a response, then the SMTP is working.
Now to skip all that auth issue, give that mass mailing machine a static IP and configure the SMTP Service on the Exchange to allow relay from that ONE particular LAN IP.   That way, it won't care of authentication or anything else and just accept the mail.

Where can I check the status of the SMTP Service? I cant seem to find it under Windows Services or under Exchange Console. I have set customer receive connectors before. The machine is already static so it should be easy.

"Start" -> "Run"
Type "cmd" or "command"

And do from Richard post:

Test the Exchange SMTP by doing a telnet from another machin

telnet exchange.ip 25

if you get a response, then the SMTP is working.

Yes it connects. I assume I need to make a new "Receive Connector" and list just that machines ip? Then I should be able to turn off all authentication settings in the program?

Well, enable relay: http://blogs.techrepublic.com.com/networking/?p=373
And turn off auth. settings in the program.

Your problem sounds similar to allowing a Printer / Scanner / device that does not have built in authentication to scan and e-mail documents. The following link should assist you with your query:

You will have to add the required "receive connectors" in the Hub transport section. (if you open your Exchange Management Console and navigate to the Server Configuration - Hub Transport)
Hope this helps

Just create a receive connector on your server - HUB.
Tabs:
  general: FQDN: give it a name like relay.internaldomain.local
  Permissions: configure it to allow anonymous connections.
  Network: on the bottom, best to limit it to the IP address or IP range of the workstation which has to send the e-mails.
  Authentication: Don't check anything on the tab authentication.
Don't forget to create in your DNS the name relay.internaldomain.local and point it to your HUB server
