login_access_sockets

Hi I've used Dovecot for a long time but I never stop learning about the depth of features I've never used.... I just discovered the login_access_sockets setting when reading this page: https://doc.dovecot.org/admin_manual/login_processes/ The compilation using --with-libwrap configure setting was not immediate, since on Fedora which I am using there is no tcp_wrappers-devel package so tcpd.h wasn't installed in /usr/include and the library name libwrap.so that was expected by … [View More]

IMAP login-logout cycle performance with performance mode seems slow/limited and cause cannot be found
by m＠maltris.org 03 Jul '24

03 Jul '24

Hello, I am running a test setup in a docker stack with Dovecot (2.3.21). Basically as a test to see whats possible. The whole thing works okay, but I noticed that with imaptest (latest version) somewhere between 230 and 270 requests per second on a login+logout cycle it cannot go further. However, this is a 384G memory, 48 core, dual-cpu setup that is pretty much idling (utilization somewhere around 6-12%). The ssds are not loaded at all. The memory usage is low. For testing purpose I set … [View More]nopassword=y and allowed all logins, the users just require a small mysql db lookup which is done once before the cache is filled. If I copy that exact same stack to my local machine, I yield around 450 cycles per second. And the only difference I somehow see is that my local machine has a faster cpu-memory connection and only one cpu with less cores. Is it possible memory speed is a limiting factor because of the cpu-memory-mapping on the server and the slower memory? What performance should I expect? Asking because I am planning to run a stateless client at a later point and the limited login-performance really seems to make that difficult at scale. doveconf -n: # 2.3.21 (47349e2482): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.21 (f6cd4b8e) # OS: Linux 6.8.0-36-generic x86_64 Debian 11.7 ext4 # Hostname: 4e83f0e9d630 auth_cache_negative_ttl = 0 auth_cache_size = 50 M auth_cache_ttl = 5 hours auth_cache_verify_password_with_worker = yes auth_debug = yes auth_debug_passwords = yes auth_failure_delay = 0 auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = yes auth_worker_max_count = 500 default_vsz_limit = 2 G disable_plaintext_auth = no doveadm_api_key = # hidden, use -P to show it doveadm_password = # hidden, use -P to show it doveadm_port = 2425 log_debug = event=* log_path = /var/log/dovecot-debug.log login_trusted_networks = 10.0.0.0/8 127.0.0.0/8 mail_debug = yes mail_fsync = never mail_gid = 1000 mail_location = maildir:/data/vmail/%d/%1n/%n mail_uid = 1000 managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = nopassword=y driver = static } protocols = " imap lmtp sieve pop3 submission" service anvil { chroot = empty client_limit = 75100 idle_kill = 4294967295 secs process_limit = 1 unix_listener anvil-auth-penalty { mode = 00 } } service auth-worker { client_limit = 1 process_limit = 6000 user = $default_internal_user } service auth { client_limit = 91000 } service doveadm { inet_listener { port = 2425 } inet_listener http { port = 8080 } } service imap-login { process_limit = 15000 process_min_avail = 48 service_count = 0 vsz_limit = 2 G } service imap { client_limit = 1 process_limit = 15000 } userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol doveadm { passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql name = override_fields = port=2425 ssl=no starttls=no } } protocol imap { mail_max_userip_connections = 250 } Best regards [View Less]

AW: AW: AW: IMAPSieve plugin will not run rspamd script
by postfix_dovecot＠gmx.de 02 Jul '24

02 Jul '24

Hi John, the prefix is just a sign of my desperation - I tried all sorts of variations yesterday and now forgot to undo it. There’s a very detailed tutorial available (German language) with Debian 10. Just the sieve scripts are little different. I spend the time to raise a Debian 10 with this tutorial – and with exact the same result as with my up to date configuration. So it would be interesting for me to know if there is anyone here who has managed to get this to work on Debian? … [View More] Jens Von: John Fawcett <john(a)voipsupport.it> Gesendet: Montag, 1.

Jens Hi Jens I meant the same type of logging you already posted (i.e. as below) for exactly the same test case, but where the rules use the mailbox name that includes the prefix you set for the namespace (i.e.INBOX/Spam). There is probably a good reason why you have configured a prefix for your namespace, but my suspicion is that the example imapsieve config you copied assumes no prefix set (it was not part of the example so we cannot see it). I personally tried the settings from the example and they work fine and I have no prefix. I also did the opposite test and I get the behaviour you reported when I have prefix set. In order to solve it (without changing the prefix) I had to state the full mailbox name including the prefix in the imapsieve rules. In that case it worked. What I'd like to check in your logging is if there is a clue why it didn't work for you when yu used INBOX/Spam in the rules.

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 … [View More]– 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.

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 &… [View More]

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" "… [View More]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 [View Less]

by Austin Witmer 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

Oauth2 remote IP address
by Scott Q. 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
