IPhone 4 spontaneously sends old emails to others (HUGE privacy concern)

Question

Still trying to get my head around how this happened:
1. I took a photo of something using the Camera app.
2. I went to send it to a friend by hitting Email Photo.
3. I put in their address, filled out the Subject line, hit Send, picked my resolution, the usual.
Then I go to my Send folder to make sure it sent okay, and I see something very strange: instead of the photo I was trying to send, the body of the email is actually *an exact email I sent to someone else over four years ago.*
I was puzzled. Why was such an old email appearing on my iPhone out of NOWHERE? And why did Mail send THAT as the body instead of the picture I was trying to send? At no point did I ask it to go into my email and attach anything else but the photo in question.
As it turns out, the email itself was the VERY FIRST email I sent using my .Mac account, as it was then known. But I've only had my iPhone for six months! It simply makes no sense for that email to be even IN my phone, as I haven't set it to store messages that far back (because it would be absolutely pointless to do so). Just to be sure, I went to the very end of my iPhone's Sent folder -- and it stops at a month ago, just as I set it to. So I ask again: how did it fetch this text? And more importantly: why?
Somehow, my iPhone grabbed the body of this ancient email (presumably from the MobileMe server), pasted it into the new message I was trying to send, and did all of this covertly while I thought I was just sending a simple pic?? Remember I saw NO evidence of this in the Send window -- or else I wouldn't have sent it! "Wait, that's not my picture...that's an old email from 2006! What the **** is THAT doing there??"
Please someone explain what's going on here? If this is a bug, I would say it's massive. A mail client that randomly sends old emails to people who were never meant to see them??
And it gets weirder: when I check Mail on my laptop AND through the MobileMe web portal, neither show the message in my Sent folder. But on my iPhone, it's right there. So did it actually send or not?
I'm currently waiting to hear back from my friend to see if this was the case, so who knows. But I'm freaked out enough just seeing it there!
Thankfully none of the email was especially private or scandalous, but what if it had been? Apple cannot afford to have their products going haywire and accidentally sending messages to the wrong people. This is enough to make me not want to use Mail through my iPhone ever again. I don't want to be wondering what else it's digging up every time I go to hit the Send button, ready to ship off to some other acquaintance. Brutal!
I would love to know if anyone else has had this experience, and I'd especially like to hear from Apple staff on this potentially serious security bug.
I'll update once I find out if it actually sent or not.
So bizarre!

Update:
My friend claims he never got such an email, so perhaps it's just a glitch? It's still there in my Sent folder, however, although just on the iPhone and nowhere else.
Still curious to hear from Mac officials on this!
