I am using nms formmail for the "contact us" page which collecting first name, last name, address, phone number, email and comment.  The recipient is set to "ABC@DOMAIN.COM"

When I test the form, it works fine. My email "ABC@DOMAIN.COM" receive all the info from the form but the weird thing is the email showed that it's sent from my own email address so it's like:

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------
From: ABC@DOMAIN.COM
Sent: Tuesday, March 15, 2011 11:15 AM
To: ABC@DOMAIN.COM
Subject: Customer Inquiries

Below is the result of your feedback form.  It was submitted by (ABC@DOMAIN.COM) on Tuesday, March 15, 2011 at 14:15:17
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------
So if I want to reply to the customer, I can't click the "reply" but have to copy and paste the email info from the form.

Any idea how to fix that? Appreciate it!!
