Quota clone plugin - initial population of data
by John Fawcett 15 Jan '24

15 Jan '24

Hi while responding on a previous thread, I noticed in the documentation: https://doc.dovecot.org/configuration_manual/quota_clone_plugin/ "For example you might want to access everybody’s quota via Redis ... but you don’t store the Redis database permanently so it could become empty once in a while. " It aslo seems that the quota clone plugin propagates only quota changes. Putting both of these points together, you'll going to have missing quotas in redis if it is restarted. It will gradually get populated but only on basis of mailbox changes. Maybe there should be an initial load of all the quotas when dovecot starts, or could that be a performance issue? Maybe even doveadm quota recalc should propagate or contain an option to propage quotas so that even if it can't be done on dovecot startup, at least it can be done on demand by the administrator.

ARM support
by Brad Koehn 15 Jan '24

15 Jan '24

Hey there, I was wondering if you’re planning to support ARM in your packages and/or Docker images. Right now I’m stuck on whatever ships with Debian for ARM64 architectures. Otherwise, suggestions how would I go about building them myself? In a modern build world, it’s fairly straightforward, especially with Docker to handle all the emulation. Thanks for such a great product! I’ve used Dovecot on my little server for over twenty years. — Brad Koehn Hey there, I was wondering if you’re planning to support ARM in your packages and/or Docker images.

Custom map for quota
by Matt 15 Jan '24

15 Jan '24

Hi, I'm trying to setup quota with the following layout CREATE TABLE "domain" ( "id" INTEGER, "name" TEXT, "active" INTEGER DEFAULT 0, PRIMARY KEY("id"), UNIQUE("name") ) CREATE TABLE "address" ( "id" INTEGER, "localpart" TEXT NOT NULL, "domain_id" INTEGER NOT NULL, PRIMARY KEY("id"), UNIQUE("localpart","domain_id") ) CREATE TABLE "mailbox" ( "id" INTEGER, "address_id" INTEGER, "active" INTEGER DEFAULT 0, "password" TEXT, "quota_bytes" INTEGER DEFAULT 0, PRIMARY KEY("id") ) As I like to update the quota and I like to use a dict/map I'm not sure if I can update this following: map { pattern = priv/quota/storage table = maibox value_field = dummy fields { value_field = quota_bytes id = mailbox_id } mailbox_id will be queried using password_query using: "mailbox.id as mailbox_id" Using such map I hope to be able to use: SELECT quota_bytes FROM mailbox WHERE id = '$mailbox_id' INSERT INTO mailbox (quota_bytes) VALUES ('$value') ON DUPLICATE KEY UPDATE quota_bytes='$value' Can someone help me with this ?

Unconfigurable 500 ms debounce on IMAP IDLE notifications
by Alex 14 Jan '24

14 Jan '24

Hello all, I have been investigating the reason for high end-to-end email delivery delay (>1 second to send a message to echo bot and receive a reply back) on a Postfix+Dovecot email server setup used to run the tests for Delta Chat core [1]. It appeared that most of the time was spent between the submission SMTP service accepting the mail for delivery and receiving an IDLE wakeup on the other side. Looking into the Dovecot source code, I found that all notifications from the storage to callbacks set up by IDLE are delayed by a debounce constant NOTIFY_DELAY_MSECS [2]. It appears to have been added in 2009 [3], but even before that Dovecot was only delivering notifications when a second-resolution timer is changed by at least 1, so IDLE notifications probably were delayed by half a second on average even before that. Commit message says "If the notification is done immediately, IDLE may not notice the change because it's not finished yet." This sounds like a workaround for some internal Dovecot bug. I have nevertheless tried to compile Dovecot with this constant reduced from 500 ms to 1 ms [4] and it resulted in exceptionally fast delivery without any problems caused to the Delta Chat core online test suite which is using this Postfix+Dovecot server accounts. We are running all the tests against this server and it appears to work fine. Round trip time for sending a message to an echo bot and receiving a reply back is reduced from 1.1 s to 0.2 s, which is easily visible in a chat app [5]. I wonder if this debounce delay was added as a workaround for an internal Dovecot bug or a client bug and is not necessary anymore. It does not seem to be useful for well-behaving clients because if necessary the client may debounce notifications on its side and postpone interrupting IDLE with "DONE". I would actually like to disable this delay completely on our server setup [6], as for chat it is common to receive multiple messages in a short period of time, e.g. when sending a message to a group and receiving multiple read receipts from currently active users.

Lots of "dovecot: auth: Error: auth client 0 disconnected with 1 pending requests: EOF" errors in error.log

I've recently upgraded to dovecot 2.3 and now my error.log is full of this message: dovecot: auth: Error: auth client 0 disconnected with 1 pending requests: EOF In earlier versions, this error was logged at a warning level. What is the rationale behind the elevation to error log level? May I suggest to revert this change? (fyi: the code in question is in /src/auth/auth-client-connection.c) static void auth_client_disconnected(struct auth_client_connection **_conn) { struct auth_client_connection *conn = *_conn; unsigned int request_count; int err; *_conn = NULL; if (conn->input->stream_errno != 0) err = conn->input->stream_errno; else if (conn->output->stream_errno != 0) err = conn->output->stream_errno; else err = 0; request_count = conn->request_handler == NULL ? 0 : auth_request_handler_get_request_count(conn->request_handler); if (request_count > 0) { e_error(conn->event, "auth client %u disconnected with %u " "pending requests: %s", conn->pid, request_count, err == 0 ?

Redirects 550'd So why no SRS method
by Laura Steynes 05 Jan '24

05 Jan '24

Happy New Year! Now to Aki, Timo, Corr, why, when setting up mail forwarding, is sieve not automatically configuring rules for SRS, it has this ability for long time, yet dovecots sieve based forwarding just creates a plain old redirect "forward" resulting in,in 2024, 99% of forwarded emails getting rejected for failing SPF because it's not enabling the require or the rules needed for successful sender rewriting. Is this an oversight? and I suppose the bigger question is, when is it planned to be corrected to using SRS method? Happy New Year!

Piegonhole behaviour when redirect fails
by Aubry Jaquier 04 Jan '24

04 Jan '24

Hello, I noticed an unusual behavior of the implicit keep from pigeonhole when a redirect fails in a sieve script. For instance, with the sieve below, if the relay host is unavailable, dovecot will not accept the email and will respond with a tempfail. redirect "myaddress(a)domain.com"; stop; But if my sieve script has a fileinto inside (see the example below), dovecot will accept the message, copy the email in the INBOX and in the folder from the fileinto and write the following log "Execution of script filter.sieve failed, but implicit keep was successful" fileinto "Folder"; redirect "myaddress(a)domain.com"; stop; According to the RFC 5228, section 2.10.2 Implicit keep, the last example should not trigger an implicit keep but act like the first example. An implicit keep is performed if a message is not written to a mailbox, redirected to a new address, or explicitly thrown out. That is, if a fileinto, a keep, a redirect, or a discard is performed, an implicit keep is not. Does it look like a bug to you, or is this the intended behaviour ?
