Hi, I have installed isync to synchronize my home computer's mailboxen with IMAP server in the university (IMAP is not officially supported there -- kidn of policy: "use it, but do not ask us for any help"). isync can well download all messages from IMAP, however it doesn't seem to be able to distinguish messages already downloaded with the new ones (so, it downloads old messages again) and it doesn't seem to delete on the server messages I have deleted in my local box. Any suggestions? Thanks in advance. Matej Cepl
