Hi Aki, Oops; I did not think carefully enough about your instructions.

Request: Pigeonhole - strip CWFS from message-id logs
by Lee Maguire 20 Jan '19

20 Jan '19

Normally for a log line containing the contents of a Message-Id, it is logged like the following Nov 29 11:41:27 xxx dovecot[211]: lmtp(lee)<30167><XXXXX>: sieve: msgid=<xxxx(a)example.net>: stored mail into mailbox 'Notifications' However, if there is CFWS other than a space, it changes the format of the log line (potentially making the logs harder to process - eg via “logcheck" rules) Nov 29 11:50:09 xxx dovecot[401]: lmtp(lee)<55724><XXXXX>: sieve: msgid=? <xxxx(a)example.com>: stored mail into mailbox ‘Notifications' A message-id line broken up is valid per RFC 5322 and header whitespace shouldn’t be significant for logging purposes https://tools.ietf.org/html/rfc5322#section-3.6.4 https://tools.ietf.org/html/rfc5322#section-3.2.2

Feature request: client bind address for replication
by John Fawcett 20 Jan '19

20 Jan '19

Hi would it be possible to consider a new parameter for replication: doveadm_local_ip which allows the source ip address to be set when connection to a remote dovecot for replication? It could be useful when the network interface has multiple ips and a specific one is used for mail services. See attached proposal. I tested against 2.2.36 only. It applies correctly against 2.3.4 with a warning,. John

auth-worker service failed since recent MariaDB upgrade

Hello, I have started having issues with auth-worker.

The package was rebuilt from our package maintainer due to bumping MariaDB from 10.1.x to 10.3.x. Before that, I did not have any issues at all. However, I don't see any impact from this error too, at least not for now.

Can you try with valgrind? It will slow down the logins a bit though. service auth-worker { executable = /usr/bin/valgrind -q --vgdb=no /usr/lib/dovecot/auth -w } At least one good thing about this crash is that it seems to happen only at deinit, so it's not impacting users.

Sieve: reject certain mime-types and notify recipient

I have to reject office files for a certain domain plus notifying the original recipient about the rejection too. require ["fileinto","reject","body","enotify","variables"]; if allof (address :contains ["To","TO","Cc","CC"] "@example.org", body :content "application/msword" :contains "") { set "to" "${1}"; # :matches is used to get the value of the Subject header if header :matches "Subject" "*" { set "subject" "${1}"; } # :matches is used to get the value of the From header if header :matches "From" "*" { set "from" "${1}"; } notify :message "Rejected Office Datei ${from}: ${subject}" "${to}"; reject text: Aus Sicherheitsgründen nehmen wir keine Office Dateien mehr an. Bitte senden Sie uns ein PDF. . ; } A manual sievec call gives not error and if I remove everything but the reject line it works.
