Some problems but im not sure if these would actually cause a failure, unless the receiving end thinks it looks like spam.
You end header lines with \n not \r\n
If the name in your from line has spaces you must quote the name.
You dont put a line break after the last header
The proper way:
Code:
$headers = "MIME-Version: 1.0\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\n";
$headers .= "From: \"Radio Bounce\" <>";
Please try send to a different address such as yahoo or gmail and turn off spam filters.
