I was wondering if there is some way to force an imap client to 're-download' all the messages from the inbox. I can remember in the 'old days' that when the connection was dropped during a pop download, the whole inbox was re-downloaded, resulting in quite a lot of duplicates. I am looking for such action.
You can change the UIDVALIDITY of the mailbox. This invalidates the client cache which would cause a (well-behaving) client to rebuild that mailbox from current server state.
