Hi Mike, I tried to send you an email twice yesterday to report this issue, and I got an error when I tried to send. So that’s why I started this thread. To answer your question, I have “WordPress” set for “Send E-mail function”. I’ve always had that. I sent test emails to myself using the contact form when I’m logged in WP and when I’m logged out. And both emails I received have Reply-To pointing to my domain email, and not the sender email I used on the form. I set the “Send E-mail function” to “PHP” and the same thing happened when I sent a test message. The Reply-To says my domain email.
