I'm having an issue with a contact form running on WP 3.0.1 and GF 1.4.3.1. The notification emails are sent correctly BUT they always show as being from the main WP site. So instead of showing up as being sent from webmaster@clientsite.com, they show up as being from no-reply@mainsite.com. The GF settings are correct and I've tested with various combinations of reply to and from email addresses but nothing seems to affect it. Any thoughts?
