Quoting Алексей Сундуков <public-m...@alekciy.ru>:
But I can't understand what encoding use dovecot for keywords? I set "тест" (number 5) keyword: cat dovecot-keywords 0 &bcienqrbbeiepgqybdaetw-_&bdwenqrcbdoema- 1 test 2 $label1 3 $label2 4 $label3 5 &beienqq6beeeqg- but "&beienqq6beeeqg-" do not convert to "тест". Why?
Because only mailboxes are encoded in Modified UTF-7. There is no equivalent encoding for keywords. Keywords are *not* meant to be directly viewable by an end-user. Converting between a keyword and the representation displayed to the user is the job of the MUA. michael
