I see a contradiction here: Cyrus IMAP server is designed to support multiple connections but it does not work with a client that actually uses them. > one file (i.e. unix mbox format).

Is it possible to force Cyrus IMAP server to use some kind of locking mechanism? For some unknown reason most users are running OE as a IMAP client and only way to solve their problems is to do something at the server side. I haven't familiar (yet :)) with internals of the Cyrus IMAP server design, so could somebody explain the background of the multiple connection support? This seems to be handy only for situations when same user is accessing imap folders using different clients. BTW, Thanks for your OE hints! heiki
