I had that issue and in my case it had nothing to do with cyrus.

In my case there was no correct utf8-encoding by the software which 
created the mail which had to be send, in detail with the name of an 
attachment: An 8-bit character in the name was used without 
utf8-encoding, which lead into the SMTPUTF8-complain by the receiving 
smtpd-server.

I solved the problem with a workaround: my php-routine turned the 8-bit 
character into 7-bit characters.

Johann
