[Plugin: Contact Form 7] From field doesn't work

No matter what I put in the From field of the contact form, I get my WordPress admin address there.

I’d like to have the default “[your-name] <[your-email]>”, which works perfectly in the message body (and in the from on my other sites). Is this perhaps caused by some limitation forced by my hosting, and is there a way to get around it?

I’m using version 2.4.4 of Contact Form.
