Reply To address in New User Notification

[arretx]

So here's a concern that I have about the system.

When someone registers, I am sent an e-mail to let me know that someone registered. If I try to reply to that e-mail, it replies to me.

I need to be able to send a reply to the notification and have it go to the user who just registered.

Here's why:

My address in Wordpress goes to a pop account that is monitored by a ticketing system which assigns a unique ticket to the request and notifies me. As it stands, I am being sent tickets as though I am the one opening the ticket, because the ticketing system bases the information off of the Reply To information in the e-mail header, and since the new user's reply-to is not there, I end up with a ticket that loops back to me.

Any ideas?
