I have Exchange 2007. I have been tasked with allowing a external program to relay through the Exchange server , for marketing email blasts. The reason for the relay is that the blast will say it is sent from my email domain. Currently we are sending these through a 3rd party company but some of the emails are being caught in spam filters due to the header being spoofed (to make it look like it comes from my server).
The blast is usually to around 500 recipients.
Here are my questions:
1)What do I need to check on Exchange to make sure that it can support the added volume? CPU and mem look fine on it but I am scared that when a email blasts happens , that it will prevent email from being sent/received in a timely matter.
2)Would this cause the company to get black listed?
3)Are copies of relayed emails , stored in the message stores?
Thank you very much for your time and help.
