Your message cannot be saved: Javascript or iframe detected
Since version 8, Mailpro detects the presence of javascripts or iframes in your message. You have to suppress the javascript in your message to be able to save your message as the scripts are very detrimental for the deliveries of your message.
To do so, select the script menu in your message editor to show the HTML code and use the research function of your navigator. Search for "javascript" and/or "iframe" and erase the line with the scripts or iframe.
