since iOS 8 I can't configure mail for not download full content. With previous iOS I note that you can read mail in text mode and it doesn't download attached documents. You can get a good reader in iPhone screen because the text looks big. Then you can choose download full mail and attached files
Nowadays Mail in iOS work downloading full format of content even the documents. So you begin reading the mail and in seconds it get the mode, sometimes it transform the big text in a formatted text that you need to zoom for reading and move right/left following the sentences because it doesn't fit in the screen
Consequences of this in my case is that I eat rapidly my mobile data when I refresh my work account. Even as its a exchange account the system can't monitoring good your consumes. If you check mail usage it doesn't count Exchange accounts, it is counting in System usage. So if I turn off mobile data in Mail settings I can't get any saves of data consumes
