correct email address when sending from exchange 2010

We have an Exchange 2010 server that is accepting email for 3 domains. domain1, domain2, and domain3. We have some users that have an email address of only domain1, some with email addresses from domain1 and domain2, and some with email addresses from all 3. All are receiving mail properly and without issue the problem lies when they try to reply or send on behalf of a specific domain that is different from their "set as reply" address. Is there a way to configure Exchange 2010 to send back out with the domain that it came in on? Can a user select a specific domein/email address that is different than their "set as reply" setting. Thanks

No, you can only send out using the primary smtp address. you would need a separate mailbox that has the second email address, grant send-as permission, and have all messages for that mailbox forwarded to the other.

The only issue with this would be no ability to put in multiple exchange ammounts in Outlook 2007. I would have to configure pop3 accounts for the non default accounts?
no, you wouldn't need anything. the user would just need to ensure they changed the from field to the secondary mailbox. all messages to the secondary mailbox would be delivered to the primary.

Not nayively. You should use a third-party tool to do that. Google for "Exchange send as non-default domain".
