Email from Another

I need email confirmations to appear to come from someone else rather than me. I thought I might be able to accomplish this by adding a secondary email address to my account, but I don't think I can choose this email in the from spot. When I manually enter the email address in the from spot, the form complains upon clicking save that the mail must have zoho.adminuserid in either the from or to spot.

I understand that this behavior is desirable from a anti-spam position, but is there some way to get around this? I don't want emails appearing to come from me, when the form user really should really be contacting someone else if they have questions.

I see item # 3251000001648037 is in the development roadmap. Does that mean it's in actual development, or is that in some sort of long-range, wish list?
