Is it possible to prepare an email (From, To, Subject, Body, Attachements) in PHP and, instead of directly sending it with PHP, open it with the client's email program (Thunderbird / Outlook / ...)?
My context is :
- in a form, the user select the "To" contact and a file to send (the body is a predefined text)
- on submit, I would like the prepared email to be displayed in his favorite mail client, so that he can modify it (add CC, modify body, ...)
If possible, how to do that?
