julianbraintly on "[Plugin: Postman SMTP Mailer/Email Log] Possible error / fix for attachments with sendgrid"

in PostmanSendGridMailEngine.php line 189
$this->email->addAttachment ( basename ( $file ) );
As far as i dug (for hours)
should be:
$this->email->addAttachment ( $file );
else the send fails

cheers, hope someone finds this useful
