I don't know. I don't use readonly folders myself, and they seem to be implemented differently from server to server anyway. I'm hesitant to touch that code too much. > I assume this is the cause: > > Wed Jul 4 09:19:06 EDT 2007 John Goerzen <[EMAIL PROTECTED]> > * Correct readonly handling > Upstream imaplib now issues EXAMINE when readonly != None > offlineimap/imaplib.py's version always used SELECT The root cause is probably switching to the imaplib.py built in the Python. I think I had to adjust this because of that, but I can't remember exactly right now. > It's compliant with the RFC and I can see some practical reasons for > this; you have asked Courier to open the folder read-only, so there is > nowhere that it can save the UIDVALIDITY value without writing to the > folder. Down that path lies madness. Opening a folder read-only should refer to the ability of the client to modify things in it, not to the ability of the server to present consistent metadata. Consider this: On Monday, you connect to a Courier IMAP server and SELECT folder foo. UIDs are set and a uidvalidity is established. You disconnect and don't make any further connection attempts until Tuesday. On Tuesday, you EXAMINE the folder. Courier returns the same UIDVALIDITY as on Monday, but 50 new messages have arrived. If Courier interprets EXAMINE to mean "don't open anything writable", how will Courier store the UIDs that have been assigned to these messages, so that when you EXAMINE again on Wednesday, you get the exact same UIDs for the same 50 new messages messages? I would think that Courier would *have* to write to disk in that situation. -- John -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
