Relay mail to a backend server?

[fluoline]

I've a domain configured in Plesk but I woud like to relay to mail for this domain via the Plesk server to an exchange server.

Is it possible to relay the mail for a specific domain to a specific server.

It's important that the mail is passing by the Plesk server, because I would like to use the Spam and Virus scanning.

If anyone has any clue?!
