Working for a company which has Hosted Exchange. The internal domain name is the same as the email domain name (eg, mycompany.com). The MX records point the the 3rd party provider.
My goal is in this project is to generate alert messages from a couple network devices. Unfortunately when specifying the Hosted Exchange SMTP server, I can not provide authentication information (user/password) to the network device. All of the popular public SMTP require authentication for obvious reasons. This lead me to set up an internal IIS server with SMTP on a 2008 R2 machine.
My problem in using the internal SMTP server to generate emails. Any emails with the company domain (mycompany.com) will get queued and will not deliver. Basically I want to be able to send emails to known email account for our company. Will provide more information if requested.
Thanks
