How can I set utf-8 as folder names ? my $LANG is ru_RU.UTF-8 now.
I might misunderstand something, but why client created folder name in mUTF-7 and sieve fileinto internally converted mUTF-7 name are not the same ?

/usr/libexec/dovecot/imap-utf7 -r "тест"
&BEIENQRBBEI-				// this is like clients create mail

/usr/libexec/dovecot/imap-utf7 "&BEIENQRBBEI-"
тест					//this decoding fine

/usr/libexec/dovecot/imap-utf7 "&-BEIENQRBBEI-"
&BEIENQRBBEI-				//this is like sieve created folder looks in the mail-client programs.
