I would like to use a shared IMAP account, with multiple users accessing it simultaneously. The users would take ownership of messages by first attempting to MOVE the messages from the Inbox, into their private IMAP folder, still within the same account. Now, since there will be multiple users competing for the same messages, I naturally want only ONE of the simultaneous moves to be successful at a time.
So far, this isn't working. If I do the move from two clients, simultaneously, the messages can go to *both *destination folders - duplicates can result.
Is it possible to configure Dovecot and/or an IMAP client to behave the way I want it to? If the answer to this is YES, then I'll offer my config details. If the answer is NO, the next question is - do any email systems at all behave the way I want? (I tried a hosted Exchange/OWA service - it has the same problem)
Thanks & regards, Greg.
