Hello,

What is the proper way to add the following to all emails? We need this fix for compatibility with Outlook.

We need to add an XML namespace to our <html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:v="urn:schemas-microsoft-com:vml" xmlns:o="urn:schemas-microsoft-com:office:office">

3 Correct DPI for Images (PPI)
This piece of Microsoft Office code goes right before the closing </head> tag, and allows us to force the DPI setting that we want.

We tried to create a plugin, but is not working.

class plgAcymailingMyHeaders extends JPlugin
{

function acymailing_replaceusertags(&$email,&$user,$send = true){

$email->addCustomHeader( "");
}

}

Please advise a way to add the 2 above Outlook compatibility to emails.

Thank You.
