[creewribE]

I encounter a very strange problem with ixwebhosting.I am able to send email using the php mail() function with $subject = "test";But if $subject = "testing of information send"; then i won't be able to receive any emailBut actually "Mail sent!" was displayed in the php page.\[code\]if (!mail($email, $subject, $body, $from)) { echo "Error Sending Email!"; }else{ echo "Mail sent!"; }\[/code\]
