accept email on Exchange from internal smtp server
Posted on 2009-07-07
I have a monitoring program that sends out email through the smtp server built into Windows 2003. I have changed over to an internal Exchange server and now the email from the monitoring program is not longer received. It is probably a very easy to solve.
I just need the Exchange server to be able to accept mail from this SMTP server. The DNS MX records are correct and point to the front end mail server internally. The email is being sent from firstname.lastname@example.org. I am guessing that it is being denied since reverse DNS does not work and there is now spf record. How do I solve this? can I set up the exchange server as a smart host so it will relay the mail back to itself?
