phpmailer - The following SMTP Error: Data not accepted

Question

I\'m trying to figure out this issue for 6 hours. But there is nothing to make sense. Here is the scenario; There is a well formatted HTML template.

<         


        

Answer 1

I was using just

$mail->Body    = $message;

and for some sumbited forms the PHP was returning the error:

SMTP Error: data not accepted.SMTP server error: DATA END command failed Detail: This message was classified as SPAM and may not be delivered SMTP code: 550

I got it fixed adding this code after $mail->Body=$message :

$mail->MsgHTML = $message;
$mail->AltBody = $message;
