I have the same problem. Since yesterday I’ve recived around 50 empty emails from WordPress.
I also use ContactForm 7 but I think that sth else is cuasing this and those empty emails are send just to administrator email.
I think its some kind of spam but I have no idea how to block it (I have comments posting disable).
I will apreacite any help.
Hello gordonek
I ‘think’ I have figured out how to fix my problem so will explain what I did in the hope it can help you.
First of all, the issue was related to the email subscription form which was created using the Campaign Monitor addon. There is no captcha on the form which means that spam bots can invade.
The emails were blank because I had no information entered in the Mail fields (except the clients email). As soon as I entered information such as [your-name] <[your-email]> in the from field and something in the Subject field the spammy emails had a from name… still no subject.
I then set up Askismet which I think is what has actually solved the problem.
In your case, if you are experiencing problems with the contact form only it might be because you don’t have the captcha enabled.
Also, check to see what information you have entered in the Mail fields (group of fields below the form fields). If you don’t have [your-name] <[your-email]> in the From field any enquiries you get will say they are from wordpress.
Am still not 100% that the problem has been fixed – still monitoring the situation.
Hi,
Thanks for answer but think that in my case its sth else.
I have just recived 20 more blank emails. I think its not connected with contact form because Im getting this spam to my admin email not to one which I put in contact form.
I will install Akismet howewer and check if it will help.
Looks like installing Akismet plugin solve the problem. I havent recived blank emails for 3 days.
Thanks for the tip Calicosun 🙂
