Hi I created a form and I need send the results that people fill in the form by email, but when the submit button is clicked, this message is displayed:

Unable To Send E-Mail
We're sorry but we were unable to send your e-mail. If you are sure that you entered all your email addresses properly, you should contact your server administrator.
PHP Version: 5.2.10
Sendmail Path: /usr/sbin/sendmail -t -i
Sendmail From:
SMTP: localhost
SMTP Port: 25
MySQL: Installed
File Uploads: On
File Uploads Max Size: 2M
Post Max Size: 2M
Software Version: 8.0

Script Version: 5.0

Everything in the form is well configurated, because it works in another server, but not here in zxq.net. Please, any ideas of what is happening?

you have to pay $10 for the mail() function enabled on your account

OHHHHHHH THANK YOU VERY MUCH!!!
