[support] Contact Exposing Destination Addresses?

[Luke]

Hello

It may be that I just never noticed this before, but in contact 5.12 
running on Drupal 5.12, it seems that addresses provided to contact as the 
destination for categories, are being shown to the user as the From: and 
Reply-To: of the auto response.  To-wit:

>X-Mailer: Drupal
>Errors-To: my_site_return at address
>Sender: my_site_return at address
>Reply-To: category at destination_address
>From: category at destination_address
>Subject: [category] message_subject

I thought that the site return address should be the address provided in 
all cases.
The whole point of using the contact module for a site wide contact form, 
is so that addresses such as the category destination addresses are _not_ 
revealed to communicants.
I am 99% sure that this behavior is new to 5.12, and did not appear in 
5.7, which is what I am running on other sites.

Might this be a configuration error somewhere?

Thanks and regards,

Luke
