Exchange 2010 Send Connector

Hi

We currently have Exchange 2010 sp2 with all roles and another Exchange 2010 sp2 in Edge mode. We use Exchange to send all emails, including emails sent from the software we sell (sent over 1 millions email last month sent from 1 account).

We are going into online archiving and there are some limitation in terms of usage.

Is it possible in exchange to route all emails from user abc@abc.com to use send connector1  and then all other accounts to use send connector2?

THanks for your help.
