Hi! Does the duplicate sieve plugin do any locking to avoid duplicate parallel delivery of the same message? I sometimes experience duplicate mail delivery of messages with the same message-id, despite the use of a sieve duplicate filter. According to the log files, those messages are delivered in the same second by two parallel dovecot-lda processes. (Duplicate filtering works fine in all other

I know there is a new lmtp_user_concurrency_limit setting, but there is not much documentation apart from the commit message: https://github.com/dovecot/core/commit/42abccd9b2a5a4190bd3c14ec2dcc10d51c0f491 There are possibilities from within the MTA as well I expect.
