I have 2 Edge Transport Server, with Subnet 192.168.1.0/24
I have 3 Exchange Server (HUC, CAS, and Mailbox Server) with Subnet 192.168.2.0/24
I have a legacy application server, it will automatically generation report and supporting that sends out email through exchange server.
It's designed to allow communication between individuals in two separate (program specific, non-Exchange) distribution lists. Both of these distribution lists are populated with seemingly random email addresses (Yahoo, Gmail, Hotmail, etc). we’re configure email relay on exchange server to allow email to outside world.
My application is IP address 192.168.2.10 will sending the email out by using external email address such as firstname.lastname@example.org, email@example.com, firstname.lastname@example.org...etc through the exchange server then edge server to the outside world.
Unfortunately, send email with the header FROM of the individual in the first list, and the TO of a person in the second list. Obviously, we're not authoritative for those domains, so we're dealing with the issue of showing up on email blacklists almost constantly since we appear to recipients as a classic spammer.
I would like to filter on Hub or Edge server all email come from my application server with IP address 192.168.2.10 will rewrite all email to email@example.com.
Is it possible to rewrite outbound headers?
Do you have any idea or solution?
