[Dovecot] simultaneous access to folder
We have for many years been a UW-IMAP site, with users having their own traditional, private, mbox-format INBOX and folders: almost (but not quite) no complications of shared or simultaneous access. We have just completed a transparent transition to dovecot (official 1.0.0 release). But we have one residual issue affecting one important user account. UW-IMAP specifically only allows single access to mbox folders. If different IMAP connections are attempted to such a folder, the latest attempt kills off earlier connections. (That's just the way it works, which was mostly fine for us.) On this particular account we had explicitly set two folders to UW-IMAP's different mbx format, so that a group of staff could simultaneously access that folder and delete messages. This is by a single, common, id/pw account. But dovecot doesn't support mbx format. Is there a way for us to set up such a group-access folder under dovecot? I've checked wiki pages such as http://wiki.dovecot.org/SharedMailboxes; but that doesn't seem to be clear on the particular matter of which formats are suitable for such simultaneous access. It talks about different users accessing a folder; in our case it is multiple instances of the the same user. Under dovecot, can we simply let it be mbox format? And can dovecot (unlike UW-IMAP) then handle the simultaneous access? [Background: this is just two folders (amongst many) on one username; the overall service successfully handles over 15,000 usernames. And the solution (work-around) will only need to last a few months until that whole account is Exchange-ified (but let's not digress...!)] If I've missed something on the wiki which addresses this matter, point me in the right direction... -- : David LeeI.T.

We have just completed a transparent transition to dovecot (official 1.0.0 release). Congratulations! We did this nearly two years ago and now I'm using Dovecot proxying to move users transparently to Exchange (against my better judgement/prejudices) :( But we have one residual issue affecting one important user account.

We converted all our similar mbx-format files back to mbox when we migrated.
