Webtolead Response with info@ email?

HI - any thoughts on how we can make the web-to-lead response use generic "Thank you" email addresses (ie info@abc.com) instead of from a specific user?  

We have a number of different sites / use cases, and it doesn't make sense to have a uwer license for each instance when we only need the email sent.   

Thanks ...
