The message was forwarded so many times that the indentations / quoting of the original text really built up, leaving basically no room for original text.
You can see what I mean if you rotate the phone to landscape.
And then the default left/right indents on BLOCKQUOTE tags (default - baked into Android) are rather large.
I made a change to use smaller indents (by default, if not explicitly specified in the HTML), this will be present in the next "official" Play update, hopefully tonight.
Re: "but it displays correctly in Outlook and web mail".
A "Hey, it's different in app A and app B" trumps any reasoning, every time.
How about "app C"?
A little known mail app called Thunderbird shows your message with same enormous margins.
And "app D"?
Web mail, Mail.ru (one of Russia's largest Internet and e-mail companies) same thing.
"App E"?
Yahoo web mail. Same huge margins.
Not to mention that the "correctly" (in "displays correctly in Outlook") implies that Aqua's display of this message is somehow "incorrect".
Nope, it's exactly what is there in the message's HTML code.
