I deleted a message by storing the \Deleted flag and called expunge. The message was deleted then, but in the file dovecot-uidlist the filename of that message is still listed, even after logging out and in again, doing select and check. When will this file be updated?

It's only used for figuring out UIDs for existing files, so entries for expunged mails are just ignored. It's updated whenever new messages are written there, the old entries are removed then.
