OK, I'm a newbie, and I hope this hasn't been covered too many thousand times before. What I want to do is generate html emails that get generated within the default mail application on the client side. I want to it this way rather than use something like phpmailer so that the users can utilise system address books, personal address books etc.
As this is for an intranet and everybody uses Outlook, then this is what it should open into to.
So far I've tried sending the following header
header("Content-type: message/rfc822");
But this results only in Outlook Express starting, which is definitely not the default email client.
Any clues??
