PHPMailer With Attachment Never Received - php

Question

I am tying to send an email with an attachment using phpmailer.
include_once('/home/site/PHPMailer/class.phpmailer.php');
$mail = new PHPMailer();
$body = $mail->getFile('contents.html');
$body = eregi_replace("[\]",'',$body);
$mail->IsSMTP(); // telling the class to use SMTP
$mail->Host = "smtp.free.fr"; // SMTP server
$mail->IsSendmail(); // telling the class to use SendMail transport
$mail->From = "name#sub.fr";
$mail->FromName = "name";
$mail->Subject = "subject";
$mail->AltBody = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test
$mail->MsgHTML($body);
$mail->AddAddress("sub#sub.net", "name");
$mail->AddAttachment("mylist.csv"); // attachment
if(!$mail->Send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else {
echo "Message sent!";
}
I receive a "Message sent !" on execution, but no email is ever received.

Answer 1

It is very possible the user you sent the email to did not recieve it due to the fact a lot of mail providers such as AOL and Yahoo block massive amounts of Ip addresses related to email spam. So if the server you are running this php script from is on their blacklist the user will not even receive it to the spam folder.
Check your php email logs.

Also, if this is not the case, try making sure the file your trying to include exists, and you are passing the correct path to the file. Like #Waygood said, try seeing if it sends without the attachment.
