Actually, if you restore from backup to another Cyrus instance and can log in it's very easy using search-extended:
telnet restoreserver 143 . login username password . select INBOX . UID SEARCH RETURN () UNSEEN * ESEARCH (TAG ".") UID ALL 1015337,1015340:1015366,1015378:1015379,1015381,1015384 . logout telnet productionserver 143 . login username password . select INBOX . uid store 1015337,1015340:1015366,1015378:1015379,1015381,1015384 -flags \Seen . logout And you're done :) Repeat the search for any other mailbox.
