Using the send mail function, can I send email from a second email address, not just the zoho.adminuserid?

I'm thinking of creating a form with a dropdown list asking if you have problem A, B or C. Can I customise the send mail comfirmations so that A queries receive a response from a@mywebsite.com, B queries from b@mywebsite.com etc?
