Cyrus 2.4 and vacation problem (smtputf8)

[Josef Karliak]

   Good morning,
   I upgraded servers to new Postfix versions, we had some issue with 
bounced vacation with czech characters. But postfix has smtputf8 support 
enabled :
smtputf8_enable = yes
smtputf8_autodetect_classes = sendmail, verify

   and the issue with emails (vacation) persists.
   After some checking I've found that thereis not postfix that bounce 
the message - it is cyrus'es LMTP, listenning on TCP/24:
Sep 13 08:08:12 postman11 postfix/cleanup[2916]: 59F2A280DB7:

host postman.domain.cz[1.2.3.101])
Sep 13 08:08:12 postman11 postfix/qmgr[2885]: 59F2A280DB7: removed

   So do I need to set something in cyrus config ? What did I missed ?
   Thanks and best regards
