I had something out of the ordinary come up and was wondering if the IronPort would be able to handle something like this.
Receive messages from partner smtp server destined to public email domains. However, we want the sender (from: ) to be an address with our domain name. Of course if they were to send the message from their smtp server out directly the customer with our domain name, the security on their end should pick it up as a spoofed sender address because the domain name doesn't match the sending email server via dns and mx lookups.
Is there way I can instruct the partner to send directly to my ironport and I setup a content filter/listener or something that will grab the message from their specific IP.
My ironport would then ignore any RAT inspection but send the message out it's external interface to the recipient as if were coming from my environment?
Thanks in advance, kind of a time sensitive issue.
