Two Different Service Emails

Hey guys, we just recently implemented the latest version of ServiceDesk, and we're quickly getting used to the program.

I guess this could fit under multiple forums, but I picked Tips and Tricks just to play it safe. Is there a way we can have multiple emails for the service desk creating tickets? Right now, it's setup so that all emails come from HelpDesk@domain.com, but we have email configured so that all mail sent to HelpDesk automatically opens a new ticket.

So, I guess that's really two questions:
1) Can we configure anything in ServiceDesk so that emails coming into two different accounts can generate tickets?
2) Can we configure anything in ServiceDesk so that there will be different auto responder for different email accounts. Like if tickets come in through HelpDesk@domain.com, auto-responder1 will be sent and for tickets through TechAdmin@domain.com, auto-responder2 will be sent.

Any help would be super awesome. Thanks!
