@paul2009 I receive a lot of, what seems to be, automated spams even though the site uses Captcha. I've added a screenshot of the emails I get. All the emails are exactly the same: the name is repeated twice, and there are arbitrary words in the form fields. Any idea how they're able to send this? I receive multiple emails every day. I don't know how I could filter these away... I wish Gmail filters supported regex. 🙂
