This is my first post here so please be gentle.
I'd like to set up an email router to achieve the following:
1. Email sent to email@example.com
gets routed to email server 1
2. Email sent to firstname.lastname@example.org
gets routed to email server 2
All email for domain.com hits a firewall and would then be NAT'd to the email router. It's at this email router that I want to be able to split email for user 1 and user 2.
I'm sure this is possible and probably quite simple to achieve but I honestly don't know where to start.
Any advice would be greatly appreciated.
Please let me know if you need any further info.
