Zucca100 on "[Plugin: Contact Form 7] Wrong Email address in From:"

I've just upgraded the Contact Form 7 to 3.3.3
When I receive a form that the clients have filled, the sender's email address is replaced with codes, as below:
From: XXX <[your-email]@xxx.xxx.co.uk>
Would anyone know how to fix this.
I'm not a developer and the simplest resolution would be appreciated.
