i need help with drupal webform basically when someone fills the form it dosent send it to my email can someone help me please asap thank you
Do you mean the http://drupal.org/project/webform module ? Or are you using the default contact form ? The default contact form has Categories. Have you added the categories correctly ? Its hard to provide any solution without seing the site, but it could also be issue with your email settings on your server that prevents it from sending mail. Check the server logs too.
+1 on what nmridul said. In addition, have you checked Drupal's logs, too? Those might show what's happening. Also, try registering a new account - is an email sent out? (Assuming you've configured Drupal to send an email upon account creation.) If one isn't sent out and you've configured Drupal to send one, then this is a good indicator it's a mail setup issue on your hosting.
I agree with ryan_uk, if you're running Cpanel, make sure the email address that you set as the sender email in Drupal exists in Cpanel else it might be sending the email and going to the SPAM folder of the receiver and therefore not show up in the Inbox. Hope this makes sense. Good luck!
