Is it possible to have multiple MX records pointing to multiple mail servers for a single domain? Must all mail accounts be identical on each of those servers, or is it possible to have email@example.com set up only on one mail server, and firstname.lastname@example.org set up only on the other mail server?
The reason for this is the need to use two different email service providers but still keep everything at a common domain.
My understanding of MX record functionality tells me this scenario won't work, that each server will respond with "mailbox not found" errors for the accounts not on that particular server. Help?
