yes, there must be something wrong with the construction of the message with attachment... right now i'm trying to look at this
wish me good luck
edit: solved
the html portion of the message wasn't closed with the correct boundary, so the receiving client thought that the whole attachment was part of the html portion of the mail
to solve this issue, edit includes/vbms_class_mail_message.php, search for
PHP Code:
if (!$hasattachments) { $headers .= VBMS_CRLF . "--$delim--" . VBMS_CRLF; }
and change it to
PHP Code:
$headers .= VBMS_CRLF . "--$delim--" . VBMS_CRLF;
