Is it possible to get the device type/name from which an email was sent?

As you can see there's the Mime versio and X-Mailer that both contain iPhone. But is this so with for example a Nokia N97 or other type of phone?[/quote]

Honestly I don't know but I would assume that each type of phone or mobile email service sends something similar. Perhaps google will shed some light. If headers are not consistent you may have to look at originating mail server or have a failover default.
