I just read an email on hotmail of about 129K. There was actually no message, just a white space.

Looking at the source of the page I noticed this:

ChangeIfUtf8("0");
</script>
<title>MSN Hotmail - Message</title>
<link rel="stylesheet" href="/cgi-bin/dasp/EN/hotmail___906000056.css">
<script language="JavaScript" src="/cgi-bin/dasp/EN/hotmail___906050002.js"></script>
<script event=onload for=window language=vbscript>
on error resume next
dim MsngrObj
set MsngrObj = CreateObject("MSNMessenger.HotmailControl")
If Err.Number <> 0 Then

this part may be nothing, but I'm sure there's something strange about the email. Can anyone explain this?
