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

[quote author="bretticus" date="1253666248"][quote author="codex" date="1253663874"]I'm wondering how some sites, for instance Flickr, 'know' from what device (iPhone, Blackberry) an email was sent. I don't see that information in an emailheader. So how do they know?

EDIT: Hmm, something tells me I have to take a look at EXIF data...[/quote]

I doubt there's EXIF data in the email itself, but they look at the email headers no doubt. Do you have access to the headers via SMTP transaction? What headers are you looking at?[/quote]

My bad. I was confusing the image attachments (that contains the EXIF data) with the actual email.

I get the headers via IMAP. For instance, an email that was sent from an iPhone contains this:

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?
