1) Search the boards to see if this question has been asked before.
2) Please post what version of PHPFormMail you are using.
3) If your mail is not being sent, please list what type of server you are using (Unix/Windows)
4) Please try to post a link to the form that is sending the data to PHPFormMail.
5) Please remove any redirects (to thank you/error pages) in your form. It's a lot easer to find the problem when we can see the native formmail.php errors.
6) Do not post the same question more than once.
