PHPMailer and 100K file limit for attachments? - php

Question

I'm trying to send a file as an email attachment, but for some reason if the file is > 100k then the email doesn't go through, even though I get the email sent message.
It may also be a limit on the attachments in IIS smtp setting, but when I unchecked the Limit session size and limit message size options, it didn't change anything. I may have to restart the server tonight...
I don't know if it's a php.ini setting, or what.
<?
$path_of_attached_file = "Images/marsbow_pacholka_big.jpg";
require 'include/PHPMailer_5.2.1/class.phpmailer.php';
try {
$mail = new PHPMailer(true); //New instance, with exceptions enabled
$body = $message; //"<p><b>Test</b> another test 3.</p>";
$mail->AddReplyTo("admin#example.com","Admin");
$mail->From = "admin#example.com";
$mail->FromName = "Admin";
$mail->AddAddress($to);
$mail->Subject = "First PHPMailer Message";
$mail->AltBody = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test
$mail->WordWrap = 80; // set word wrap
$mail->MsgHTML($body);
$mail->IsHTML(true); // send as HTML
if($attach){
$mail->AddAttachment($path_of_attached_file);
}
$mail->Send();
echo 'Message has been sent.';
} catch (phpmailerException $e) {
echo $e->errorMessage();
}
?>

I might be wrong because I don't use IIS but the code you provided would actually use a native MTA not SMTP. As far as I know you have to use the IsSMTP() method to let PHPMailer know that you intend to use SMTP.
Something like this:
<?
$path_of_attached_file = "Images/marsbow_pacholka_big.jpg";
require 'include/PHPMailer_5.2.1/class.phpmailer.php';
try {
$mail = new PHPMailer(true); //New instance, with exceptions enabled
$body = $message; //"<p><b>Test</b> another test 3.</p>";
$mail->IsSMTP(); // telling the class to use SMTP
$mail->Host = "mail.yourdomain.com"; // SMTP server
$mail->SMTPDebug = 2;
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->Host = "mail.yourdomain.com"; // sets the SMTP server
$mail->Port = 25; // set the SMTP port
$mail->Username = "yourname#yourdomain"; // SMTP account username
$mail->Password = "yourpassword"; // SMTP account password
$mail->AddReplyTo("admin#example.com","Admin");
$mail->From = "admin#example.com";
$mail->FromName = "Admin";
$mail->AddAddress($to);
$mail->Subject = "First PHPMailer Message";
$mail->AltBody = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test
$mail->WordWrap = 80; // set word wrap
$mail->MsgHTML($body);
$mail->IsHTML(true); // send as HTML
if($attach){
$mail->AddAttachment($path_of_attached_file);
}
$mail->Send();
echo 'Message has been sent.';
} catch (phpmailerException $e) {
echo $e->errorMessage();
}
?>

Your code is not actually checking if the message was sent or not.
You need to change your code to check the return of the send method
if ($mail->Send())
echo 'Message has been sent.';
else
echo 'Sorry there was an error '.$mail->ErrorInfo;
This should give you the error message saying what is up if it does go wrong.
