dovecot-lda: timeout for external scripts called by sieve
by Meinhard Schneider 28 Jul '24

28 Jul '24

Hello, I have a small problem with dovecot-lda. I am using Debian 12 Bookworm: root@lnxmail01:~# dovecot --version 2.3.13 (89f716dc2) Historically grown (probably still from sendmail times, long time ago) I always used procmail for local e-mail delivery. This also included the call for spamc for SpamAssassin. I have now changed this and set up a route via sieve. There is a small script for this: root@lnxmail01:~# cat /usr/lib/dovecot/sieve-filter/spamc-filter.sh #!/bin/bash /usr/bin/spamc My sieve configuration says (in extracts): root@lnxmail01:~# head -12 ~meini/.dovecot.sieve ## Generated by Roundcube Webmail SieveRules Plugin ## require ["body","comparator-i;ascii-numeric","copy","envelope","fileinto","imap4flags","include","regex","relational","spamtestplus","vacation","variables","spamtest"]; include :global "spamc"; # rule:[Spam] if spamtest :value "ge" :comparator "i;ascii-numeric" "5" { fileinto "Spam"; stop; } In general, this has been working for many months without any problems. But sometimes the whole thing fails due to a timeout: Jul 7 22:00:13 lnxmail01 dovecot: lda(meini)<766014><G9l7JcPzimY+sAsAmbNf3A>: Error: program exec:/usr/lib/dovecot/sieve-filter/spamc-filter.sh (766016): Execution timed out (> 10000 msecs) Jul 7 22:00:13 lnxmail01 dovecot: lda(meini)<766014><G9l7JcPzimY+sAsAmbNf3A>: Error: program exec:/usr/lib/dovecot/sieve-filter/spamc-filter.sh (766016): Forcibly terminated with signal 15 Jul 7 22:00:13 lnxmail01 dovecot: lda(meini)<766014><G9l7JcPzimY+sAsAmbNf3A>: Panic: output stream (temp iostream in /tmp/dovecot.lda. for (program client seekable output)) is missing error handling Jul 7 22:00:13 lnxmail01 dovecot: lda(meini)<766014><G9l7JcPzimY+sAsAmbNf3A>: Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(backtrace_append+0x42) [0x7ff00aee04e2] -> /usr/lib/dovecot/libdovecot.so.0(backtrace_get+0x1e) [0x7ff00aee05fe] -> /usr/lib/dovecot/libdovecot.so.0(+0xfc49b) [0x7ff00aeec49b] -> /usr/lib/dovecot/libdovecot.so.0(+0xfc501) [0x7ff00aeec501] -> /usr/lib/dovecot/libdovecot.so.0(+0x53aee) [0x7ff00ae43aee] -> /usr/lib/dovecot/libdovecot.so.0(o_stream_unref+0x5e) [0x7ff00af1003e] -> /usr/lib/dovecot/libdovecot.so.0(program_client_destroy+0x8e) [0x7ff00ae6ee6e] -> /usr/lib/dovecot/modules/sieve/lib90_sieve_extprograms_plugin.so(sieve_extprogram_destroy+0x18) [0x7ff00aacd8f8] -> /usr/lib/dovecot/modules/sieve/lib90_sieve_extprograms_plugin.so(+0x556d) [0x7ff00aacb56d] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_interpreter_continue+0xea) [0x7ff00ab4c9ba] -> /usr/lib/dovecot/libdovecot-sieve.so.0(ext_include_execute_include+0x2c7) [0x7ff00ab72e17] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_interpreter_continue+0xea) [0x7ff00ab4c9ba] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_multiscript_run+0x82) [0x7ff00ab62b32] -> /usr/lib/dovecot/modules/lib90_sieve_plugin.so(+0x37a3) [0x7ff00abd47a3] -> /usr/lib/dovecot/libdovecot-lda.so.0(mail_deliver+0x176) [0x7ff00b11f906] -> /usr/lib/dovecot/dovecot-lda(main+0x879) [0x55ef085e4fb9] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xea) [0x7ff00ac3ad0a] -> /usr/lib/dovecot/dovecot-lda(_start+0x2a) [0x55ef085e56ea] The worst thing is that the entire mail is lost (/dev/null)! Then I tried to set the timeout higher (than the current 10 seconds): root@lnxmail01:~# doveconf | grep -A 12 ^plugin plugin { sieve = file:~/sieve;active=~/.dovecot.sieve sieve_execute_exec_timeout = 60s sieve_extension_exec_timeout = 60s sieve_extensions = +vnd.dovecot.filter +spamtest +spamtestplus sieve_filter_bin_dir = /usr/lib/dovecot/sieve-filter sieve_filter_socket_dir = sieve-filter sieve_global = /usr/lib/dovecot/sieve-global sieve_plugins = sieve_extprograms sieve_spamtest_max_value = 5 sieve_spamtest_status_header = X-Spam-Level sieve_spamtest_status_type = strlen } I have set both the values for "sieve_execute_exec_timeout" and "sieve_extension_exec_timeout" to 60 sec, but according to the log, this does not seem to affect the 10000 msec mentioned therein. The SpamAssassin daemon has enough child processes to handle the requests (most of them were idle at the time of the error). How can I configure that the external script gets more time for execution? And what can I do so that - should the script terminate contrary to expectations or be killed in the timeout - the mail is not lost but simply processed further? Many thanks & best regards Meinhard

Looking for Some Help with Dovecot Configuration for IMAP Access
by Selena Thomas 27 Jul '24

27 Jul '24

Hi everyone, I am having a bit of trouble setting up Dovecot for IMAP access. I’ve installed Dovecot and configured the main configuration file,, but I am not sure if I missed something important. Here’s what I have so far ::- 1. Dovecot Version: 2.3.11 2. OS: Ubuntu 20.04 3. Configuration Files: - `/etc/dovecot/dovecot.conf` - `/etc/dovecot/conf.d/10-ssl.conf` - `/etc/dovecot/conf.d/10-auth.conf` I can connect to the server, but I’m having issues with mailbox access and authentication. Does anyone have any tips or common pitfalls I should check: ?? Any guidance would be greatly appreciated..... Thanks in advance...

Sieve duplicate detection not working as expected
by Rosario Esposito 26 Jul '24

26 Jul '24

Hi, On a dovecot server (2.3.21) I have a simple sieve script: require ["duplicate"]; # rule:[duplicate] if duplicate { discard; stop; } I use virtual users with mail aliases on a LDAP backend. I have user "resposit" having 2 mail aliases: - resposit(a)na.infn.it - rosario.esposito(a)na.infn.it If I send a single message to both aliases I still receive 2 copies as you can see from the attached log. Is the "duplicate" sieve extension supposed to work this way ? Any help would be much appreciated ! -- Rosario Esposito

SMTPUTF8 support
by Dāvis Mosāns 26 Jul '24

26 Jul '24

Hi, I'm interested in SMTPUTF8 support in Dovecot. It seems it's still not implemented? Any plans on implementing it? How much work would it be? I couldn't find any mention of this functionality. Postfix has support which is enabled by default but it's not usable if Dovecot doesn't support it. Thanks! Best regards, Dāvis

Re: [EXT] Re[8]: Sieve Filters with MySQL

It's OK to hide it to the mailbox table as sieveFilterID. Then you can do map { pattern = priv/sieve/name/default table = mailbox username_field = email value_field = sieveFilterID } Aki > On 26/07/2024 10:14 EEST Adam Miller <adam(a)ardaemail.com> wrote: > > > ------ Original Message ------ > From "Aki Tuomi via dovecot" <dovecot(a)dovecot.org> > To "Adam Miller" <adam(a)ardaemail.com>; "Adam Miller via dovecot" > <dovecot(a)dovecot.org> > Date 7/23/2024 10:06:38 PM > Subject Re: Re[6]: Sieve Filters with MySQL > > >Hi! > > > >Usually how the "isActive" stuff is done is bit different. > > > >fwiw i would do the schema differently, and have two tables > > > >table 1: > > > >CREATE TABLE sieve_name_id ( > > id INT, > > email VARCHAR(255), > > name VARCHAR(255), > > PRIMARY KEY(email, name) > >) > > > >table 2 > > > >CREATE TABLE sieve_scripts ( > > id INT, > > content TEXT > >) > > > >Then you can map 'default' to the active script id, or leave it missing when there is no script enabled.

sieve mail date change
by Marc 24 Jul '24

24 Jul '24

I am a bit rookie with sieve. Some time ago I created a sieve pipe that would sometimes alter alter the subject and move a message to a different mailbox. Currently this results in that a date changes of this message while I don't see anything in the source altering a date. What could be causing this and how to work around this?

Sieve Filters with MySQL
by Adam Miller 24 Jul '24

24 Jul '24

Me again! I am trying to get sieve filters working with a MySQL backend but same to be coming up short. Right now, the error I am getting received is: ------------------------------------------------------------------------------------------------------------------ "User has no active script in storage dict:proxy::sieve;user=username@domain.com" ------------------------------------------------------------------------------------------------------------------ The “username(a)domain.xn--com-9o0a is obviously the email address of the receiving mailbox.

When I run manually queries, everything works fine though I am not entirely sure what the queries are that Dovecot is executing. Any help is appreciated! Also, if I could use the “isActive” field, that would be great as well. My plan to start here is to only have one record in the table per mailbox which would contain all Sieve filters. Eventually, it would be nice if I could adjust the configuration to allow for more than one that returns concatenated so any help there would be great as well! Thank you!

Key metrics to monitor for dovecot at CloudWatch
by Sivakumar Vadivel 24 Jul '24

24 Jul '24

Hello Team, Configured dovecot mail server and SES will receive and forward to SNS topic. Lambda subscribed to the topic and it will receive the mail and write to the EFS volume. EFS volume mounted on both dovecot and lambda. Also enabled AWS Cloudwatch to monitor overall infra. I'm going to enable anomaly detection at Cloudwatch and I want to know the list of key metrics to monitor. I'm thinking of the following metrics. 1. No of bounce 2. PublishFailed & Success 3. EFS disk storage Please suggest the other key metrics, so that I can enable anomaly detection to understand and create the cloudwatch alarm.

Dovecot Stats Plugin
by Adam Miller 23 Jul '24

23 Jul '24

Hello again everyone! I am trying to get the “doveadm stats dump” command to work and even though it does not error, there are no stats. When I try to enable the stats, I get the following error: “Error: Plugin 'stats' not found from directory /usr/lib/dovecot/modules” which is correct, the “stats” plugin does not exist. I do have “/usr/lib/dovecot/stats”.

Dovecot proxy/director/replicator upgrade path
by Andrea Gabellini 23 Jul '24

23 Jul '24

Hello, I manage a Dovecot installation version 2.3.4.1 with a pair of proxy/director in front and two backends that use the replicator plugin to synchronize emails between them. I would like to update all 4 machines and would like to understand if I can directly jump to the latest version 2.3.21 and if there is a logical sequence to follow, such as updating the backends first and then the frontends or vice versa.
