[SOLVED] Error - Bad parameters with PHP Mail funtion - please help

I switched web hosting companies and my mail statement worked fine with the old company but with the new company I keep getting this error:

Warning: mail() [function.mail]: Bad parameters to mail() function, mail not sent. in /home/content/h/e/w/hewittm/html/registration.php on line 171

Here is my code, any suggestions would be greatly appreciated:

if (mail($To, $Subject, $Body, $Headers)) {
   print "<meta http-equiv=\"refresh\" content=\"0;URL=thankyou.htm\">";
   } else {
   print "<meta http-equiv=\"refresh\" content=\"0;URL=error.htm\">";
}

what are the values of $To, $Subject, $Body, $Headers ?

Nothing Special......

$To = "user@domain.com";

$Subject = "Test";

$Body = "nothing special";

$Headers = "From: " . $FirstName . " " . $LastName . " <" . $Email . ">\r\n";

$Headers .= "Bcc: user2@domain.com";

Does the new host require certain headers?

I would contact your host and see what is required to get it to work.

Here are some option's.

1.- Check your PHP version.

2.- Mail your hosting company and report it to them.

3.- Try removing the Bcc: Header's and see if that work's.

Try removing the headers all together and add them in line by line to find your problem. My guess is your hosting company doesn't allow a From header that is outside of your domain. This is becoming more and more common among hosting services as a security measure

Along those same lines, the From: address should always be a mail box hosted at the sending mail server and you should use the Reply-to: address for any user entered email address.

Give this a try for your header separators (which are \r\n now) -

Note: If messages are not received, try using a LF (\n) only. Some poor quality Unix mail transfer agents replace LF by CRLF automatically (which leads to doubling CR if CRLF is used). This should be a last resort, as it does not comply with » RFC 2822.

Got it!  Thanks guys

Here's what the problem was, you were right PFMaBiSmAd, I removed all \r\n from the headers info and it works now.

You guys rock!

Have a great day.
