Like I expected ... there are external images loaded. Only they are not 
loaded by javascript but by standard HTML:

| <img class=3D"header_logo_size" width=3D"75" height=3D"30"
| src=3D"http://ww=
| w.gstatic.com/youtube/img/email/email_logo.png" border=3D"0"
| style=3D"displ=

| <img class=3D"avatar-size" src=3D"https://lh3.googleusercontent.com/

| heigh=
| t=3D"20" border=3D"0">

Well, those were only two, maybe there are more - it is no fun reading 
ugly HTML code and therefore I stopped after finding two. So the email 
was certainly downloaded completely but the external references were not 
downloaded as well, which is a good thing IMHO. After all spammers use 
such external images to verify email addresses. And probably youtube 
also verifies with these images that you have read the mail.
