Thank you very much for such wonderful support. Your website is truely amzaing. I had customized and downloaded forms from here. Form is getting feeded in DB but it is not getting mailed. Email is not working. Please give me some solution as soon as possible.

Did you get any error message when you submited the form? Since you didn't write it, I'll assume there were no error messages. Then most likely the form was successfully passed to your mail server but the mail server couldn't pass it to the destination mail server. The problem could be your mail server or the destionation mail server. Normally you would test mail servers in some other ways such as sending emails in command line, but it's ususally beyond casual users. You can try a different mail server to see if it makes any difference. Also try a different destionation email address. It could give some hints about which one is the problem, your mail server or the destionation mail server.
