Hi Alain, > Are you sure the cache of the imap client you are using is really in > sync with both client ? I've checked from both Outlook and Thunderbird, Vista and Centos. Anyway, I know the drill so between the runs a "dm user.xxx" and then a "cm" was performed AND the accounts deleted and created again on the client(s); I'm sure the client cache is out of the question. ... Wait, here's the final argument against the client cache: a simple ls *. | wc -l shows the number of files to be different in the respective folders. > Are you sure the source mailbox in not corrupted?
