Hello, I'm using DekoBoko plugin to create contact form at my blog. The form works perfectly (including recaptcha etc) - the only problem is that when I fill in all information and press submit, I get this error: I've taken a look into DekoBoko plugin file and I found out that it is using wp_mail() function to send the email instead of ordinary php mail(). I've also tried replacing wp_mail() with mail() but I get the same error. I am trying to send emails through this form to email account which is on my VPS and is fully functional so there's no problem. I'm using Wordpress 2.5.1. Here is the contact form: http://seowebtips.com/contact/ Please take a look at it and please suggest me what might be a problem.
