Cyrus IMAP complains about chars outside 0-127 range (chars from 128-255 range).
Cyrus has no idea which charset should be used to represent them.
[ e.g. Koi (russian), ISO-8859-2 (central european), ... ]

You sending php script should properly encode headers to explicitly
declare charset used in every header. How to do it easily in PHP is a
PHP question, not a Cyrus-IMAP question  :-)
