MIME is completely independent from SMTP.  Actually, that's kinda the 
whole point.  The MIME encoding happens entirely within the DATA portion 
(body and headers) so it looks just like a regular text message to the 
servers.

If you want to see what a MIME encoded email looks like, send yourself 
an email with attachment and then hit Ctrl-U on the message (I see you 
are using Thunderbird).
