Wrong email headers on contact form

I just noticed that is not possible for a listing owner receive an email from a potential customer and reply directly to him.

The problem is that the email header doesn’t get the email entered on the contact form as the one that should be used for reply. In other words, when using the listing contact form, the listing owner become the email, but when he reply, the email used is from the admin.

This results on the site admin being flooded with reply’s that are directed to the listing owner, since all users (listing owners) will hit the reply button without noticed that they replying to the admin email.

Now, from my point of view, this should be a must on a theme with these characteristics but I need to know if there are any known “workaround” or if Mark will correct this?
