Aki,

yes all mailboxes are in a nfs share. Concurrent access could be
possible as I have several MUA (my desktop and my mobiles). Although
only the client on my desktop (evolution) is currently doing something.
My mobiles are "sleeping" atm.

Do you think the nfs share could be the culprit?

Cheers

Concurrent access to mailboxes on different backends is not supported and is
considered dangerous. You need to use something, e.g. dovecot director, to
ensure all sessions for a user end up in same backend.
