Did downgrading help? I've still no ideas why it would have been doing that with v1.1.. On Tue, 2008-09-23 at 08:24 +0100, Yates Ian Mr (ITCS) wrote: I'm confused by this as well.

[Dovecot] Mailbox consistency with multiple clients
We're experiencing a problem with a shared account, where multiple users are accessing it at the same time there seems to be a problem where the view one user sees is not the same as the other users. This includes experiences such as deleted mail reappearing, moved mail not arriving at a destination. I'm running the latest release of dovecot (1.1.3) with the following settings. Any help would be appreciated.
