IMAPSieve plugin will not run rspamd script

Host: VMware Workstation 14.1.8 OS: Debian 12 (Bookworm) Dovecot: 2.3.19.1 Postfix: 3.7.10 Mailclient: Outlook 2016 Hello, I am currently working on a new mail server to replace my Debian 10 mail server. For preparation, I use VMware Workstation to learn and test the installation steps. When I'm eventually done, I'll rebuild my root server from scratch. This time, my problem is getting the IMAPSieve plugin working to trigger rspamd if mail gets moved to the junk folder. Sieve runs well – if rspam recognizes a spam mail, it will be transferred to the junk folder. For me it looks like the IMAPSieve plugin recognizes the move but will not running the script behind. I can see some actions in the log but nothing happens on the rspamd side where the log is also open to view. Moving a mail with Outlook produces the following log entry: imap(mail(a)test.example)<1797><a/FKmgIcqKvAqB4a>: Debug: Module loaded: /usr/lib/dovecot/modules/lib95_imap_sieve_plugin.so imap(mail(a)test.example)<1797><a/FKmgIcqKvAqB4a>: Debug: imapsieve: mailbox INBOX/Spam: APPEND event imap(mail(a)test.example)<1797><a/FKmgIcqKvAqB4a>: Debug: sieve: Pigeonhole version 0.5.19 (4eae2f79) initializing imap(mail(a)test.example)<1797><a/FKmgIcqKvAqB4a>: Debug: sieve: include: sieve_global is not set; it is currently not possible to include `:global' scripts. imap(mail(a)test.example)<1797><a/FKmgIcqKvAqB4a>: Debug: sieve: Sieve imapsieve plugin for Pigeonhole version 0.5.19 (4eae2f79) loaded imap(mail(a)test.example)<1797><a/FKmgIcqKvAqB4a>: Debug: sieve: Sieve Extprograms plugin for Pigeonhole version 0.5.19 (4eae2f79) loaded imap(mail(a)test.example)<1797><a/FKmgIcqKvAqB4a>: Debug: imapsieve: Static mailbox rule [1]: mailbox=`Spam' from=`*' causes=(COPY APPEND) => before=`file:/usr/lib/dovecot/sieve/report-spam.sieve' after=(none) imap(mail(a)test.example)<1797><a/FKmgIcqKvAqB4a>: Debug: imapsieve: Static mailbox rule [2]: mailbox=`*' from=`Spam' causes=(COPY APPEND) => before=`file:/usr/lib/dovecot/sieve/report-ham.sieve' after=(none) imap(mail(a)test.example)<1795><iC6JmQIcnqvAqB4a>: Debug: imapsieve: mailbox INBOX: FLAG event (changed flags: \Deleted) imap(mail(a)test.example)<1795><iC6JmQIcnqvAqB4a>: Debug: sieve: Pigeonhole version 0.5.19 (4eae2f79) initializing imap(mail(a)test.example)<1795><iC6JmQIcnqvAqB4a>: Debug: sieve: include: sieve_global is not set; it is currently not possible to include `:global' scripts. imap(mail(a)test.example)<1795><iC6JmQIcnqvAqB4a>: Debug: sieve: Sieve imapsieve plugin for Pigeonhole version 0.5.19 (4eae2f79) loaded imap(mail(a)test.example)<1795><iC6JmQIcnqvAqB4a>: Debug: sieve: Sieve Extprograms plugin for Pigeonhole version 0.5.19 (4eae2f79) loaded imap(mail(a)test.example)<1795><iC6JmQIcnqvAqB4a>: Debug: imapsieve: Static mailbox rule [1]: mailbox=`Spam' from=`*' causes=(COPY APPEND) => before=`file:/usr/lib/dovecot/sieve/report-spam.sieve' after=(none) imap(mail(a)test.example)<1795><iC6JmQIcnqvAqB4a>: Debug: imapsieve: Static mailbox rule [2]: mailbox=`*' from=`Spam' causes=(COPY APPEND) => before=`file:/usr/lib/dovecot/sieve/report-ham.sieve' after=(none) imap(mail(a)test.example)<1795><iC6JmQIcnqvAqB4a>: Debug: imapsieve: mailbox INBOX: FLAG event (changed flags: \Seen) My /etc/dovecot/local.conf looks like this: ## dovecot.conf # Mailuser im Log mit Namen darstellen verbose_proctitle = yes protocols = imap lmtp sieve ## 10-auth.conf # Disable LOGIN command and all other plaintext authentications unless # SSL/TLS is used (LOGINDISABLED capability).

Any help is very appreciated! Thanks Jens

Oauth2 introspection mode bug(?)
by Scott Q. 01 Jul '24

01 Jul '24

Here goes another oauth2 question, hoping it won't be ignored like all the others. I want to use get/auth on tokeninfo_url but post on introspection_url but dovecot doesn't let me. It doesn't add the auth header on tokeninfo_url whenever introspection_mode == post so, if introspection_mode = post, then dovecot no longer sends auth header to tokeninfo_url . Is this by design, is it a bug ? as can be seen in src/lib-oauth2/oauth2-request.c if (add_auth_bearer && http_client_request_get_origin_url(req->req)->user == NULL && set->introspection_mode == INTROSPECTION_MODE_GET_AUTH) { http_client_request_add_header(req->req, "Authorization", t_strdup_printf("Bearer %s", input->token)); }

Sieve Symlink Error
by Benjamin Rose 01 Jul '24

01 Jul '24

Hello, I'm in the process of moving our mail server from RHEL 6 to RHEL 9. We will be moving to: # dovecot --version 2.3.16 (7e2e900c1a) My issue is that sieve does not appear to work on the new setup, where it does work on the old one. I made a simple filter rule: # cat /u/mail0test/.sieve/ingo.sieve # Sieve Filter # Generated by Ingo (http://www.horde.org/apps/ingo/) (06/28/2024, 11:14:52 PM) require "fileinto"; # Test if header :comparator "i;ascii-casemap" :contains "Subject" "filtertest" { fileinto "Fun"; stop; } Upon sending an email to this test account, the following appears in /var/log/maillog: Jun 29 23:19:56 mail5 dovecot[3066980]: lda(mail0test)<3066980><FA8fFtzOgGZkzC4AuM9lWg>: Warning: sieve: file storage: Active sieve script symlink /u/mail0test/.dovecot.sieve is broken: Invalid/unknown path to storage (points to /u/mail0test/.sieve).

I've set the following directives in /etc/dovecot/conf.d/90-sieve.conf via puppet: augeas { "dovecot_sieve_settings": context => "/files/etc/dovecot/conf.d/90-sieve.conf", changes => [ "set plugin/sieve_dir ~/.sieve", "set plugin/sieve_user_log ~/.sieve/log" ], require => Package["dovecot"], notify => Service["dovecot"]; } The full configuration dump is attached. /u in our environment is the path for user homedirs, which is an NFS mount to a NetApp. The OS is Springdale Linux 9.2, a clone of RedHat from before the IBM license change. It will soon be RHEL 9.4 as we have obtained a license, but for all intents and purposes, Springdale 9.2 and RHEL 9.2 should be considered bug-for-bug compatible. The arch is x86_64 with both machines mail5 and mail6 (replicated) having Intel(R) Xeon(R) Gold 6244 CPU @ 3.60GHz and 768gb of memory. I have the same issue with SELinux in both enforcing and permissive modes, so this is not a permissions error due to SELinux. Am I doing something wrong, or is this a bug? I've seen that there have been some previous issues similar to this that ended up being bugs in pigeonhole, so here I am. Thanks, Ben

Glean all from addresses from a users mailbox?
by Austin Witmer 01 Jul '24

01 Jul '24

Hello all! Is there a quick and easy way to search through an entire mailbox for a user on my dovecot server and glean all the “from” email addresses? This user would like a record of all the email addresses who have contacted him. Thanks in advance for your ideas. Austin Witmer

Timeout when opening folder
by Entrepreneur AJ 28 Jun '24

28 Jun '24

Hi all, I'm stuck with an issue. Migrating everything to a k0s kubernetes cluster, trying to migrate dovecot and all so far seems to be well with PVC for mail storage, ssl working great, authentication vis PostgreSQL working great. Issue is when trying to look at another folder say Deleted or Spam etc folder I am getting a timeout error with no logs. I disabled apparmour on the nodes the try again and the following error message appears; Jun 24 21:01:55 imap-login: Info: Login: user=<eaj>, method=PLAIN, rip=194.207.0.0, lip=10.244.24.235, mpid=15, TLS, session=<eTNaF6kbzJHCz3qg> Jun 24 21:01:55 imap(eaj)<15><eTNaF6kbzJHCz3qg>: Debug: Added userdb setting: mail=maildir:/srv/vmail/eaj Jun 24 21:01:55 imap(eaj)<15><eTNaF6kbzJHCz3qg>: Debug: Effective uid=1000, gid=1000, home=/srv/vmail/eaj Jun 24 21:01:55 imap(eaj)<15><eTNaF6kbzJHCz3qg>: Debug: open(/proc/self/io) failed: Permission denied Jun 24 21:01:55 imap(eaj)<15><eTNaF6kbzJHCz3qg>: Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:/srv/vmail/eaj Jun 24 21:01:55 imap(eaj)<15><eTNaF6kbzJHCz3qg>: Debug: maildir++: root=/srv/vmail/eaj, index=, indexpvt=, control=, inbox=/srv/vmail/eaj, alt= Jun 24 21:01:55 imap(eaj)<14><3PRZF6kb0JHCz3qg>: Debug: Mailbox INBOX: Mailbox opened Jun 24 21:02:24 imap(eaj)<15><eTNaF6kbzJHCz3qg>: Debug: Mailbox Sent: Couldn't open mailbox in list index: Storage size changed 160 != 396 Jun 24 21:02:24 imap(eaj)<15><eTNaF6kbzJHCz3qg>: Debug: Mailbox Sent: Mailbox opened Jun 24 21:02:24 imap(eaj)<15><eTNaF6kbzJHCz3qg>: Debug: Mailbox Drafts: Couldn't open mailbox in list index: Storage size changed 160 != 396 Jun 24 21:02:24 imap(eaj)<15><eTNaF6kbzJHCz3qg>: Debug: Mailbox Drafts: Mailbox opened Thunderbird keeps showing a timeout error after a few minutes.

Oauth2 remote IP address
by Scott Q. 27 Jun '24

27 Jun '24

Anyone knows how to configure Dovecot to send the real remote ip address of the user to the oauth2 provider ( Keycloak in this case ) ? Right now I see the request as coming from the Dovecot server... Thank you, Scott

sieve comparator i;unicode-casemap RFC5051
by Alexey 25 Jun '24

Hello. Am I right that currently there is no chance to compare non-ascii characters case-insensitive? (UTF-8 strings from inside Subject or Body) I'm looking for :comparator i;unicode-casemap, but can't find it. It is described in RFC5051. Regards, Alexey

logging computer name
by hp＠hungpham.no 25 Jun '24

25 Jun '24

I am running Dovecot 2.3.21. One client has multiple computers in their LAN, connecting to my server with a static IP. One or several computers in that LAN keep logging in with failed password, but the Dovecot log only shows the public static IP, like this Jun 25 10:39:20 server-name dovecot[689]: imap-login: Disconnected: Connection closed (auth failed, 2 attempts in 62 secs): user=<xxxx(a)domainyyy.com>, method=PLAIN, rip=client-public-IP, lip=server-IP, TLS, session=<MCLxoK4bksIO8zXR> I tried to enable debug, but there is no more information about the LAN IP or computer names. Is there any setting which helps me with that purpose? So it will be much easier to locate the failed computers in that LAN? Thank you.

No, I meant Thunderbird's rules and filters. If your mail reader decides to not save the message, IMAP and Sireve will never see it. Joseph Tam <jtam.home(a)gmail.com>

Only some of my sent emails are stored in sent-folder
by Nils 21 Jun '24

21 Jun '24

Lots of the emails I send aren't stored in the sent folder. It seems that it mostly (but not always) work for sent emails where the main email-address (the one that is also used as login name) is used as sender. It never seems to work when an alias is used as sender name. There isn't any entry in the mail.err log and nothing that looks suspicious to me in the regular mail.log. I didn't notice it at first, because I usually don't check my sent folder that much, but I it seems to have started when I migrated to the new server a few weeks ago. Any idea what could be the reason for it?
