Sieve replication - Debian 9.11 - Dovecot 2.2.7 - script changes not replicated
by Daniel Botting 14 Oct '19

14 Oct '19

Hi, I am trying to setup Sieve replication, it is almost working: 1/ Create a script - sync'd across 2/ Activate/de-activate a script - change sync'd 3/ Delete a script - change sync'd But if I make a change to a script it is not replicated, unless I de-activate and activate again. I am seeing in the logs the below during this process (de-activating/activating): Oct 9 17:01:39 hostname dovecot: dsync-local(a_user): Debug: doveadm-sieve: Iterating Sieve mailbox attribute: vendor/vendor.dovecot/pvt/server/sieve/files/0910-active-1640 Oct 9 17:01:39 hostname dovecot: dsync-local(a_user): Debug: doveadm-sieve: Value missing for key `vendor/vendor.dovecot/pvt/server/sieve/default' (last change: 2019-10-09 17:01:37) # 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.16 (fed8554) # OS: Linux 4.9.0-3-amd64 x86_64 Debian 9.11 auth_debug = yes auth_debug_passwords = yes auth_verbose = yes default_vsz_limit = 0 doveadm_password = # hidden, use -P to show it first_valid_gid = 8 first_valid_uid = 8 last_valid_gid = 8 last_valid_uid = 8 lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes mail_debug = yes mail_gid = 8 mail_location = maildir:~/Maildir mail_plugins = " notify replication" mail_uid = 8 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 editheader imapflags 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 = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { mail_replica = tcps:replication_server_url:port_number sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +editheader +imapflags } protocols = " imap sieve pop3" replication_max_conns = 4 service aggregator { fifo_listener replication-notify-fifo { user = mail } unix_listener replication-notify { user = mail } } service auth { unix_listener /var/run/dovecot-exim-bridge { mode = 0660 user = Debian-exim } } service doveadm { inet_listener { port = 12345 ssl = yes } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } process_limit = 512 process_min_avail = 4 service_count = 1 } service imap { process_limit = 1024 } service managesieve-login { inet_listener sieve { port = 4190 } process_min_avail = 1 service_count = 8 vsz_limit = 256 M } service managesieve { process_limit = 1024 } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0666 } } ssl = required ssl_cert = </path/certs/a_domain/fullchain.pem ssl_client_ca_dir = /etc/ssl/certs ssl_key = # hidden, use -P to show it userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap override_fields = home=/var/mail/%u uid=mail gid=mail } verbose_ssl = yes protocol lda { mail_plugins = " notify replication sieve" } protocol imap { mail_max_userip_connections = 32 mail_plugins = " notify replication" } protocol sieve { mail_max_userip_connections = 10 managesieve_logout_format = bytes=%i/%o managesieve_max_line_length = 65536 } Kind regards -- Daniel Botting

Password issue
by ＠lbutlr 13 Oct '19

13 Oct '19

One of my accounts was having login failures when trying to send mail, but was able to check mail. I tried everything I could think of to see what the issue might be, but eventually went in and reset the password in the sql database (I knew the password, so I reset it to the same password). {SHA256-CRYPT}$5$VuS… {SHA256-CRYPT}$5$VI7… So the password was updated properly. Clients can still login to check mail, but are failing to send mail, so the password was not the issue. First, logins in to check mail and succeeds > Oct 09 16:02:16 imap-login: Info: Login: user=<myuser(a)covisp.net>, xx.xx.xx.xx, PLAIN, TLS Sends device MUA info > Oct 09 16:02:16 imap(myuser(a)covisp.net)<84553><bP4acIGUJttJDqGg>: Info: ID sent: name=iPad Mail, version=17A860, os=iOS, os-version=13.1.2 (17A860) Fails to send mail > Oct 09 16:02:50 imap-login: Info: Aborted login (auth failed, 5 attempts in 33 secs): user=<myuser(a)covisp.net>, xx.xx.xx.xx, PLAIN, TLS Postfix logs "Client host rejected: Access denied” but as I said, other accounts can submit and there’s nothing special in the submission service in master.cf. Passwords are all copied/pasted so identical in both IMAP (p993) and SMTP (p587) settings. Settings for the SMTP server are identical to the other accounts using the same server. I don’t know how to login to IMAP via the openssl command line interface, but this is what happens when I login to the submission port.  % openssl s_client -connect mail.covisp.net:587 -starttls smtp … auth login 334 VXNlcm5hbWU6 base64(username)= 334 UGFzc3dvcmQ6 base64(pasword)= DONE (Same results without the terminating ‘=‘) I’m sure I am missing something really obvious? -- Lithium will no longer be available on credit

Error: SSL_accept() syscall failed

In setting up my new mail server, I am getting the following in the logs: Oct 11 07:10:59 kumo dovecot[5704]: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=24.53.79.10, lip=172.26.12.90, *TLS handshaking: SSL_accept() syscall failed: Success*, session=<B9OokqCUD+UYNU8K> I have tried various ssl_protocols entries, but for now have defaulted back to ssl_protocols = !SSLv3 (the "out of the box" setting).

Using maldet
by Ignacio García 10 Oct '19

10 Oct '19

Hi there. Sometimes I notice that some malware gets through amavis+clamav+postfix and lands in the user's maildir files. I wonder if it would make sense, or even if it would be advisable to scan and clean those files using a program as maldet Thanks for your help. Ignacio

Case sensitivity in :addresses in sieve vacation scripts
by Julian Kippels 10 Oct '19

10 Oct '19

Hi, I have recently updated from Dovecot 2.2 to 2.3. Since I have noticed that vacation responses from sieve are not working the same anymore. For example, my sieve script looks like this: vacation :days 1 :addresses ["Kippels(a)hhu.de","julian.kippels(a)hhu.de"] it used to be that I got a vacation response if I sent a mail to kippels(a)hhu.de and Kippels(a)hhu.de. Now I only get a response for Kippels(a)hhu.de, not for kippels(a)hhu.de. I cant say for sure, but I suppose this behaviour changed with the update. If not, why could this have happened? And in any case, how can I enable case insensitivity? Thanks Julian

Dovecot core debug
by MediumDave 10 Oct '19

10 Oct '19

Hi all, I have a Dovecot core that I am trying to track down, in an attempt to replicate so I can log a bug report, and am hoping others might be able to help me as I’m reaching my limit. My working theory is that two user sessions are active at the same time, one of the sessions is “mid-search” (or perhaps in idle state) on a virtual folder where the number of results is zero (due to a null results array), when another session either performs an append or perhaps a new message arrives in the virtual view and qualifies for the search. It seems that the current list of UID’s in the search results is zero (null), and new messages are being appended to the search results, which results in a divide by zero. But I have not been able to create a scenario to replicate this on my test box, but is occurring regularly (every hour or so) on my mail server. I have been able to replicate on my test box using a single account by performing many random operations over and over again, with multiple sessions, but took over 24 hours and I can’t isolate the action that caused it. Dovecot version is 2.2.36 (1f10bfa63) as shipped with Centos 7 (latest update). If I can reproduce, I can then test the latest 2.3 and see if this is still a problem in that version. Here is the full back trace: #0 0x00007f8d40636e58 in array_count_i (array=0x557be80cc168) at array.h:155 No locals. #1 array_get_i (count_r=<synthetic pointer>, array=0x557be80cc168) at array.h:209

Recommendations for shared storage
by Dan 09 Oct '19

09 Oct '19

Hello all, This email is by no means an "Educate me step by step" query, But more of an inquiry about which direction to go based on your experience. I've been working with Dovecot for some years now, so the configuration of that piece is no stranger. However, Choosing the right style of shared storage has proven to be somewhat of a challenge. A bit of background of what I need to provide service for: ~80,000 users, that will potentially grow throughout the future ~100 unique domains Ability to scale horizontally. As resources grow, adding a node (or group of nodes) with the exact configuration as the other nodes. Director should be able to send the connection to a node that has the same data as it's neighbors, Allowing high availability. What I've experimented with so far: _Server pairs, using dsync to replicate data between the nodes - Director to send users to a specific pair (director_tag returned from passdb) _ Pros: - Easy way to replicate data, without the need for external tools Cons: - Limited to one pair of nodes - dsync doesn't replicate all sieve files, for example, one file that tracks out of office replies has not been replicated in my experience _NFS storage managed by corosync and pacemaker - Director to send users to any backend _ Pros: - One location for all data. New nodes that get stood up will be easy to configure Cons: - Complex to set up In your experience, what did you choose for mail storage? Thanks.

Hello List, I have to install a "new" system, what is the best way for this. I like to install a CentOS System but I only found dovecot for CentOS 7 is this compatible for CentOS 8 or have I to setup a CentOS 7 System ? The onboard dovecot is 2.2.36-5 :-( Thanks for a answer, -- mit freundlichen Grüßen / best regards Günther J. Niederwimmer

ITERINDEX not showing subfolders.
by Erik de Waard 08 Oct '19

08 Oct '19

# 2.3.4.1 (f79e8e7e4): /etc/dovecot/dovecot.conf Hello, we're using mail on NFS and the indexes on localdisk, with a director setup. (18K+ users) now to get more performance i thought to use the ITERINDEX option. however this has the side-effect on some mailboxes that it doesn't show the subfolders under INBOX. they seem 'disappeared'. Removing the ITERINDEX option fixes this again. Deleting the local indexes to be recreated doesn't solve the problem. What could cause this? and how to fix it. # 2.3.4.1 (f79e8e7e4): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.4 () # OS: Linux 4.9.0-11-amd64 x86_64 Debian 9.11 # Hostname: somemail.host.domain auth_cache_negative_ttl = 0 auth_cache_size = 10 M auth_cache_ttl = 1 days auth_username_chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@#" default_client_limit = 1500 default_vsz_limit = 1 G disable_plaintext_auth = no info_log_path = /dev/null listen = * log_timestamp = "%Y-%m-%d %H:%M:%S " login_trusted_networks = 10.0.10.0/24 mail_fsync = never mail_max_userip_connections = 100 mail_prefetch_count = 10 mail_privileged_group = mail mailbox_list_index_include_inbox = yes mmap_disable = yes 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 = INBOX. separator = . type = private } passdb { args = username_format=%{rip} /etc/dovecot/passdb default_fields = noauthenticate=y driver = passwd-file } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { sieve_execute_bin_dir = /etc/dovecot/sieve-executables sieve_global_extensions = +vnd.dovecot.execute sieve_plugins = sieve_extprograms } protocols = imap lmtp service anvil { unix_listener anvil-auth-penalty { mode = 0600 } } service auth { user = root } service imap-login { client_limit = 6000 process_limit = 4 process_min_avail = 4 service_count = 0 vsz_limit = 600 M } service imap { client_limit = 1 process_limit = 1024 service_count = 50 } service lmtp { inet_listener lmtp { port = 24 } } ssl = no ssl_cert = </etc/dovecot/dovecot.crt ssl_key = # hidden, use -P to show it userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } verbose_proctitle = yes protocol lmtp { mail_fsync = optimized mail_plugins = " sieve" plugin { sieve = ~/filters.sieve sieve_after = /etc/dovecot/sieve/after.sieve sieve_before = /etc/dovecot/sieve/before.sieve } userdb { args = /etc/dovecot/dovecot-sql-lmtp.conf driver = sql name = } } dovecot-sql.conf driver = mysql connect = host=10.0.10.150 dbname=maildb user=mail password=5ecret! default_pass_scheme = SHA password_query = select login as user, crypt_sha1 as password, home as userdb_home, uid AS userdb_uid, gid AS userdb_gid, concat('maildir:',maildir,':INDEX=/data/indexes/',login,':ITERINDEX',':VOLATILEDIR=/data/indexes/',login) as userdb_mail from mailbox left join aliases on aliases.systemid = aliasid where login = '%u' and inactive = 0; user_query = select home, maildir as mail, uid, gid from mailbox left join aliases on aliases.systemid = aliasid where login = '%u' and inactive = 0; iterate_query = select distinct login as user from mailbox;

Is imap "list" required before imap "select" for shared folder?
by Gene Smith 08 Oct '19

08 Oct '19

I set up a shared mailbox with dovecot and it basically works. However, before I can imap SELECT or STATUS the shared mailbox I have to first do an imap LIST, i.e, . list "" * If list is not done first, the imap select or status command on the shared mailbox results in a "NO" response with "mailbox doesn't exist" response text. I can provide more information if this is not expected behavior. -gene

Dovecot proxying to some backend using LOGIN proxy_mech
by Sébastien Riccio 06 Oct '19

06 Oct '19

Hello list, I am currently testing a setup for a PoC wit this configuration. - 1 x Frontend dovecot for proxying IMAP/POP3/LMTP/ManageSieve/Submission - 2 x Backend dovecot with local mail storage The frontend does the user authentification and communicate with the backends using a master password The fronted accepts PLAIN and LOGIN auth mechanisms and talk with backends using PLAIN auth mechanism (with the master password). This works very well, it's cool. Then, I've added to this setup an existing mail server (running another mailserver software) as a 3rd backend, and would like the frontend to also proxy for this, but this time not using master password. This is working for IMAP/POP3 when it uses PLAIN auth, but not for Submission. The backend server in this case only accepts LOGIN auth and not PLAIN on port 587. So I found out there is a field in the passdb we can add (proxy_mech), and I've set it to LOGIN. The frontend seems to now use LOGIN auth mech to talk to this 3rd backend, but the authentication still fails. According to the backend logs, tt seems dovecot proxy is now using LOGIN auth, but sends garbage as username and/or password. Also IMAP that was working when using PLAIN doesn't work anymore with LOGIN. Might this be a bug or this setup shouldn't be supported at all ?

imapsieve administrator scripts are not executed in the order they are defined
by frankagainstthemachine＠gmx.de 06 Oct '19

06 Oct '19

Dear dovecot developers, I have an issue with the Pigeonhole IMAPSieve Plugin and the order in which administrator scripts are executed. Although I cannot find anything about the order in which the scripts are executed, I would expect they are executed in the order they are defined: the one defined by imapsieve_mailbox1_* before the one defined by imapsieve_mailbox2_* in case both match. I defined several administrator scripts; among them one that should be executed when copying a mail to mailbox "Inbox", and one that should be executed when copying a mail from a mailbox "*.Spam" to any other mailbox. No matter in which order I define the two scripts, the one related to "Inbox" is always executed first when I move a mail from "blah.Spam" to "Inbox", see the snipped from my logs below. I guess there might be a bug in file imap-sieve-storage.c, function imap_sieve_mailbox_rules_match(...): The comment in this function states "Insert sorted by rule index", but in case the index of the rule to be inserted is higher than any index already in the "rules" array, the rule is inserted in position 0 instead of being appended to the end, because "insert_idx" is initialized with 0. Since the rule for "*.Spam" is a pattern rule, it is the first rule to be inserted into "rules" (in imap_sieve_mailbox_rules_match_patterns(...)). Afterwards the rule for "Inbox" is always inserted at position 0 (in imap_sieve_mailbox_rules_match(...)), no matter if its rule index is higher or lower than the index of the other rule. The following change could fix this: - unsigned int insert_idx = 0; + unsigned int insert_idx = array_count(rules); Best regards, Frank ----- log ----- [...] Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: imapsieve: mailbox INBOX: MOVE event Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: sieve: Pigeonhole version 0.5.7.2 (7372921a) initializing Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: sieve: Sieve Extprograms plugin for Pigeonhole version 0.5.7.2 (7372921a) loaded Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: imapsieve: Static mailbox rule [1]: mailbox=`*.Spam' from=`*' causes=(COPY) => before=`file:/usr/lib/dovecot/sieve/spamassassin-learn- spam.sieve' after=(none) Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: imapsieve: Static mailbox rule [2]: mailbox=`*' from=`*.Spam' causes=(COPY) => before=`file:/usr/lib/dovecot/sieve/spamassassin-learn- ham.sieve' after=(none) Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: imapsieve: Static mailbox rule [3]: mailbox=`INBOX' from=`*' causes=(COPY APPEND) => before=`file:~/.dovecot.sieve' after=(none) Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: imapsieve: Matched static mailbox rule [2] Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: imapsieve: Matched static mailbox rule [3] Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: sieve: file storage: Using Sieve script path: /var/spool/mail/ user/.dovecot.sieve Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: sieve: file script: Opened script `.dovecot' from `/var/spool/mail/ user/.dovecot.sieve' Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: sieve: file storage: Using Sieve script path: /usr/lib/dovecot/sieve/ spamassassin-learn-ham.sieve Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: sieve: file script: Opened script `spamassassin-learn-ham' from `/usr/ lib/dovecot/sieve/spamassassin-learn-ham.sieve' Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: sieve: Opening script 1 of 2 from `/var/spool/mail/user/.dovecot.sieve' Oct 4 23:51:12 somehost dovecot[22918]: imap(user)<22927><oLq3sRyU0t/AqLwV>: Debug: sieve: Loading script /var/spool/mail/user/.dovecot.sieve [...] ----- dovecot -n ----- #

Is it possible to create and use some lookup table to replace (for instance) %u in mail_location?
by Gerben Wierda 06 Oct '19

06 Oct '19

Suppose my mail_location is: mail_location = maildir:/private/var/mail/nl.rna.mail/%u But I would like to use a simple lookup table to replace %u with another value, say '8DB4E345-9144-4F92-8C9F-9D47BB61CBF8’ instead of ‘username’. Is there a (simple) way to do this?

Home Directory Creation
by Asai 06 Oct '19

06 Oct '19

Hello, I hate to have to ask this, but... why isn't the home directory being created automatically? Due to legacy compatibility we've had to use this type of home dir config: mail_location = maildir:/vmail/%d/%n mail_home = /vmail/%d/%n/home We're in the middle of upgrading to new hardware, and so I'm migrating configs to the new server, Dovecot 2.3.7 and Postfix 3.4.6 On our old server (Dovecot 2.2, Postfix 2.11) the home directory gets created automatically with a new user, but not on this one. The Dovecot debug logs just say "home dir not found." Can anyone point me in the right direction? Thank you, Asai

UNSEEN flag issues with multiple clients
by John Stoffel 04 Oct '19

04 Oct '19

Hi all, I've been bugged by this issue for a while, and while I see that the \UNSEEN flag is specified in the RFC to be reset once *any* client connects and looks at a mailbox, I was wondering if there's a way to change the behavior so that it's tracked on a per-client basis? Or if there's even some way to turn it off so that both my iPhone mail client and my main emacs viewmail mail client don't stomp over each other when looking at my mail folder counts of unread messages. My mail server is running Debian 9.11, which has dovecot 2.2.27-3+deb9u5 as the version. I'm only running IMAP, no POP at all. Thanks, John

Dovecote IMAPSieve user scripts
by Alexander Mankuta 03 Oct '19

03 Oct '19

Hello, I wonder how to configure IMAPSieve with user scripts. I can't find much information on the internet. I have Sieve and IMAPSieve for spam configured as described in the wiki and it works. Documentation mentions that imapsieve_url has to be set to appropriate ManageSieve server but no further explanation is given. What I want to achieve: let users create their own sieve scripts and execute them each time a message is being moved/copied between their mailboxes. I saw mentions of "association of user scripts with mailboxes" but I'm not sure what that means or if it's supported by Thuderbird Sieve extension (or any other software out there). Please advice. -- Regards, Alex

sieve cli
by Matthew Broadhead 03 Oct '19

03 Oct '19

i am using dovecot-2.2.36-3.el7_7.1.x86_64 on centos 7 is it possible to activate / deactivate a sieve script for a mailbox from the command line? my mailboxes are currently stores in /../vmail/domain.tld/username if i activate / deactivate a filter set using roundcube (webmail system) then it creates or deletes a symbolic link /../vmail/domain.tld/username/dovecot.sieve which points to a file /../vmail/domain.tld/username/sieve/managesieve.sieve. if i create this symbolic link manually it doesn't seem to work

Tool to give information about IP's that logged into the accounts
by Jorge Bastos 03 Oct '19

03 Oct '19

Howdy, I'm looking for a tool that can give me the information about the IP's that have logged in the accounts, for history purpose. Is there something that can grab the logs and create a database and give me this information in some nice web interface or so? Thanks in advanced, Jorge,
