Dovecot doesn't care if you use msgnums of UIDs. They both work fine. Your problem has to be something else. What exactly do you mean by "Dovecot started reindexing"? Dovecot's normal indexes or full text search indexes? How have you configured everything? Does Dovecot log anything (especially any errors/warnings about anything)?
