Also, I found this snipped in the postix documentation, that seems to  
explain it, and explains why you cannot reproduce it (you seem to run  
exim from some bounce messages I've got):

"When the Postfix SMTP server receives a message WITHOUT the SMTPUTF8  
request, Postfix handles the message as it has always done (at least  
that is the default, see autodetection below). Specifically, the  
Postfix SMTP server does not accept UTF-8 in the envelope sender  
domain name or envelope recipient domain name, and the Postfix SMTP  
client does not issue the SMTPUTF8 request when delivering that  
message to an SMTP or LMTP server that announces SMTPUTF8 support  
(again, that is the default). Postfix will accept UTF-8 in message  
header values and in the localpart of envelope sender and recipient  
addresses, because it has always done that."

The two first sentences seem to be the problem.
