Gmail and POP3

Hi everyone, I'm new to this ML. I have some issue with GMail import settings... I run a dovecot server (2.3.4.1) on Debian10 and I try to connect to my accounts from GMail. It's work fine from thunderbird in pop3,pop3s, imap, imaps... Submission work too... But it won't work on GMail except if I set ssl=yes and disable_plaintext_auth = no... Then GMail connect without SSL or TLS... And in plaintext.... Very unsecure... I can send mail with submission from GMail and ssl=require, that's ok. If I try to connect with SSL activated I've got : pop3-login: Disconnected: Too many bad commands And If I try to connect on port 995 with SSL GMail say that I have some SSL error, and the log says : auth: Debug: auth client connected (pid=21831) pop3-login: Debug: SSL: where=0x10, ret=1: before SSL initialization pop3-login: Debug: SSL: where=0x2001, ret=1: before SSL initialization pop3-login: Debug: SSL: where=0x2002, ret=-1: before SSL initialization pop3-login: Debug: SSL: where=0x2001, ret=1: before SSL initialization pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3/TLS read client hello pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3/TLS write server hello pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3/TLS write change cipher spec pop3-login: Debug: SSL: where=0x2001, ret=1: TLSv1.3 write encrypted extensions pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3/TLS write certificate pop3-login: Debug: SSL: where=0x2001, ret=1: TLSv1.3 write server certificate verify pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3/TLS write finished pop3-login: Debug: SSL: where=0x2001, ret=1: TLSv1.3 early data pop3-login: Debug: SSL: where=0x2002, ret=-1: TLSv1.3 early data pop3-login: Debug: SSL: where=0x2002, ret=-1: TLSv1.3 early data pop3-login: Debug: SSL: where=0x2002, ret=-1: TLSv1.3 early data pop3-login: Debug: SSL: where=0x2002, ret=-1: TLSv1.3 early data pop3-login: Debug: SSL: where=0x2001, ret=1: TLSv1.3 early data pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3/TLS read finished pop3-login: Debug: SSL: where=0x20, ret=1: SSLv3/TLS write session ticket pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3/TLS write session ticket pop3-login: Debug: SSL: where=0x2001, ret=1: SSLv3/TLS write session ticket pop3-login: Debug: SSL: where=0x2002, ret=1: SSL negotiation finished successfully pop3-login: Debug: SSL error: Connection closed But as I say, all is working fine from Thunderbird... For the SSL problem this is maybe because GMail doesn't like this configuration in debian for openssl ? [system_default_sect] MinProtocol = TLSv1.2 CipherString = DEFAULT@SECLEVEL=2 Maybe should I try to set MinProtocol = None CipherString = DEFAULT But this make a lot of security change on my opinion... Do someone have any tips or suggestion about my problem ? Thx Yannick

Suddenly sieve no longer working
by Heiko W. Rupp 16 Dec '19

Hey, I have a successful setup with dovecot and sieve and since a few days sieve is all of a sudden no longer working. I am on OSX and my mta is an older version of postfix (apple supplied). Has anyone gone through that and has some hints on how to best debug (and fix) that? Thanks a lot Heiko -- hwr(a)pilhuhn.de m:0179/207 4919 b:http://pilhuhn.blogspot.com

Set up fts_xapian over the weekend and re-indexed. https://github.com/grosjo/fts-xapian Tried to search my INBOX and got: > dovecot: indexer-worker: Panic: file charset-iconv.c: line 83 (charset_to_utf8_try): assertion failed: (srcleft <= CHARSET_MAX_PENDING_BUF_SIZE) What could I possibly have lurking in my INBOX to cause that ?? -- Yarema

dovecot full text search
by Wojciech Puchar 16 Dec '19

16 Dec '19

what FTP module should i use instead of squat that is probably no longer supported or no longer at all? i want to upgrade my dovecot installation. it currently uses squat but i found it often crashes on FTS on large mailboxes. i found "xapian" addon for dovecot but while it works excellent AFTER database is created, i found it need like 20 or so minutes to index less than 10GB of mails and while doing this - generate many tens of megabytes/s constant write traffic on it's database files. Excellent way of killing SSD. something must be broken. my config is plugin { plugin = fts fts_xapian fts = xapian fts_xapian = partial=2 full=20 verbose=0 fts_autoindex = yes fts_enforced = yes # fts_autoindex_exclude = \Junk # fts_autoindex_exclude2 = \Trash } any ideas?

Bug: icu linking issue in fts plugin
by Martynas Bendorius 15 Dec '19

15 Dec '19

FTS plugin seems not to be linking dynamic libraries correctly: [root@server ~]# ldd /usr/lib/dovecot/lib20_fts_plugin.so linux-vdso.so.1 => (0x00007ffd2eb95000) libicui18n.so.64 => not found libicuuc.so.64 => not found libicudata.so.64 => not found libc.so.6 => /lib64/libc.so.6 (0x00007f1cb5566000) /lib64/ld-linux-x86-64.so.2 (0x00007f1cb5b73000) ICU is in custom directory /usr/local/icu, it's not set in ld.so.conf, so, the linker would need to get this added automatically (that's how it's handled in PHP, for example): -Wl,-rpath=/usr/local/icu/lib Thank you! -- Best regards, Martynas Bendorius

Solr commit and optimize: which user?
by John Gateley 15 Dec '19

15 Dec '19

Hi, I have Solr FTR working with dovecot, and need to do the commit and optimize recommended here: https://wiki.dovecot.org/Plugins/FTS/Solr Should this run as root, or as each mail user. The documentation above implies, but doesn't state, that it is root. The docs here are similar: http://grimore.org/networking/dovecot/full_text_search But the docs here say it has to be done for each user: http://www.unixsamurai.com/dovecot-full-text-search-jetty-solr/ I don't know Solr well enough to answer. Which is correct? Thanks John

Parsing variables in config files
by Eudald Valcàrcel Lacasa 15 Dec '19

15 Dec '19

Hello, I'm trying to set up a mailbox for a bunch of domains. To do so I'm running some docker containers (I know I can use multidomain set up and I'm doing so, but I need to have some domains on different containers for specific reasons). In order to keep it all clean, I want to use different PostgreSQL databases for each container, and I'm running the container with an environment file containing database parameters, such as: DB_USER DB_HOST DB_NAME I've been trying to pass these parameters to dovecot's configuration, but they don't get parsed and I end up with messages like: dovecot: auth: Error: pgsql(%{env:DB_HOST}): Connect failed to database %{env:DB_NAME} I've tried to pass variables alone, using import_environment = DB_HOST DB_NAME DB_USER, but I'm stuck at the same errors. Is there anything I could do to fix this? Thank you! Eudald

Doveadm HTTP API and CORS
by Peter Chiochetti 13 Dec '19

13 Dec '19

While toying around with Doveadmin HTTP api I noticed, there is not much hype around it. Let's change that. Doveadmin REST API so to speak provides a web server. When doing /ajax/ requests, modern browsers block that, unless the response comes with a specific CORS header. Here how to work around with a proxy: > # /etc/dovecot/local.conf > doveadm_allowed_commands = fetch > doveadm_api_key = secret > service doveadm { > inet_listener http { > port = 8084 > } > } > # secret64 = echo -n secret | base64 > # /etc/apache/.../some-site.conf > ProxyVia Block > <Location /doveadm/v1> > RequestHeader set Authorization "X-Dovecot-API secret64" > ProxyPass http://localhost:8084/doveadm/v1 retry=0 timeout=5 > ProxyPassReverse http://localhost:8084/doveadm/v1 > </Location> Intranet only this might be good enough, TLS with username/password Basic-Authentication passthrough might be used for better security.

by Marco Giunta 13 Dec '19

13 Dec '19

Hi, I'm using Dovecot 2.2.33.2 on a RHEL 7, new installation. When I use fs:posix as dict for acl_shared_dict, like in Dovecot wiki (https://wiki.dovecot.org/SharedMailboxes/ClusterSetup) doveadm-server crash with error: # doveadm acl set -u USERNAME FOLDER user=DEST_USERNAME lookup read write-seen doveadm(USERNAME): Panic: file dict-fs.c: line 127 (fs_dict_iterate_init): assertion failed: ((flags & DICT_ITERATE_FLAG_RECURSE) == 0) doveadm(USERNAME): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x9f3de) [0x7f0e4a4b23de] -> /usr/lib64/dovecot/libdovecot.so.0(default_fatal_handler+0x2a) [0x7f0e4a4b244a] -> /usr/lib64/dovecot/libdovecot.so.0(i_fatal+0) [0x7f0e4a44377c] -> /usr/lib64/dovecot/libdovecot.so.0(+0x31688) [0x7f0e4a444688] -> /usr/lib64/dovecot/libdovecot.so.0(dict_iterate_init_multiple+0x4d) [0x7f0e4a47cadd] -> /usr/lib64/dovecot/libdovecot.so.0(dict_iterate_init+0x29) [0x7f0e4a47cb89] -> /usr/lib64/dovecot/lib01_acl_plugin.so(acl_lookup_dict_rebuild+0x3e1) [0x7f0e49a40371] -> /usr/lib64/dovecot/lib01_acl_plugin.so(acl_backend_vfile_acllist_rebuild+0x488) [0x7f0e49a3dd18] -> /usr/lib64/dovecot/lib01_acl_plugin.so(acl_backend_vfile_object_update+0x3c7) [0x7f0e49a3e867] -> /usr/lib64/dovecot/lib01_acl_plugin.so(acl_mailbox_update_acl+0x68) [0x7f0e49a41e28] -> /usr/lib64/dovecot/doveadm/lib10_doveadm_acl_plugin.so(+0x2c11) [0x7f0e48da1c11] -> /usr/lib64/dovecot/doveadm/lib10_doveadm_acl_plugin.so(+0x3060) [0x7f0e48da2060] -> doveadm(+0x2b41c) [0x556f1280b41c] -> doveadm(+0x2c01a) [0x556f1280c01a] -> doveadm(doveadm_cmd_ver2_to_mail_cmd_wrapper+0x23b) [0x556f1280ce7b] -> doveadm(doveadm_cmd_run_ver2+0x50c) [0x556f1281c73c] -> doveadm(doveadm_cmd_try_run_ver2+0x37) [0x556f1281c7d7] -> doveadm(main+0x1e4) [0x556f127fb944] -> /lib64/libc.so.6(__libc_start_main+0xf5) [0x7f0e4a071c05] -> doveadm(+0x1bd35) [0x556f127fbd35] Aborted Attached coredump and configuration.

13 Dec '19

Hi,I have a troble and can not resolve it. Please help me. I updated dovecot from 2.1.16 to 2.2.36.4. As a result, I had a client who could not access via imap. The client showed his logs (- folder not exists:INBOX ) I did not change dovecot config files. So I searched a difference between 2.1.16 and 2.2.36.4, I discovered . Please refer below results. [2.1.16] a03 list "" "*" * LIST (\HasChildren) "." "INBOX" * LIST (\HasNoChildren) "." "INBOX.Drafts" * LIST (\HasNoChildren) "." "INBOX.Sent" * LIST (\HasNoChildren) "."

INBOX.Sent * LIST (\HasNoChildren) "." INBOX.Spam * LIST (\HasNoChildren) "." INBOX.Trash For example, I noticed INBOX and "INBOX". 2.2.36.4 dovecot is no [""]. What should I do?

Lightweight LMTP daemon to avoid overkill MTA
by William Edwards 12 Dec '19

12 Dec '19

Hi, My situation is as follows. -An internet-facing spam filter relays email to destination mail server (Dovecot) with SMTP. - Dovecot should take email and deliver it to user's mailboxes. I guess I'd need LMTP for this. - An external SMTP relay is already in place. I am thinking of using Dovecot submission to relay to the external relaying cluster. So, both relaying and routing are done externally - the Dovecot machine should only store mail. Of course, there should also be a mechanism that takes care of local delivery to Dovecot, like LMTP. Usually, I would use an MTA like Exim to take care of local delivery. I feel like a fully-featured MTA is overkill, though, as all other roles such an MTA would fulfill - relaying and spam filtering - are fulfilled on external servers. Q: Does anyone know of a lightweight LMTP daemon that can take care of local delivery to Dovecot without the need for a full MTA? With kind regards, William Edwards T. 040 - 711 44 96 E. wedwards(a)cyberfusion.nl

Submission config being ignored
by William Edwards 12 Dec '19

I'm having trouble setting up submission with Dovecot proxy. The submission config seems to be getting ignored, but I'm probably doing something wrong. Expected behaviour: have messages sent to submission ports (25, 465) relayed to `submission_relay_host`. -- root@imapproxy1:~# cat /etc/dovecot/conf.d/20-submission.conf submission_logout_format = in=%i out=%o submission_relay_host = smtp.prorelay.nl submission_relay_port = 587 submission_relay_ssl = starttls submission_relay_ssl_verify = no service submission { } service submission-login { inet_listener submission_25 { port = 25 } inet_listener submission_465 { port = 465 ssl = yes } } -- What happens instead: Dovecot is attempting to send mail to the host specified in the passdb file: root@imapproxy1:~# cat /etc/virtual/xalys.nl/passwd test:$password.:8:8::/home/test.nl/test:/bin/false:userdb_quota_rule=*:bytes=0 proxy_maybe=y host=$ipaddr How do I get Dovecot to relay mail sent to submission ports to 'submission_relay_host'?

Duplicate e-mail with Dovecot and Sieve
by Claudio Corvino 12 Dec '19

12 Dec '19

Hi everyone, we have a duplicate e-mail problem with Dovecot 2.2.13 (LMTP as MDA) on a Debian 8 server. Our users are on external LDAP. We just need to setup a vacation responder (with Sieve) for our employees with a redirect to an alias (a distribution list), let's call it /LIST(a)domain.com/, that comprehends even the user that just activated the out of office. This generates a loop: when someone write to LIST(a)domain.com every user of the aforementioned distribution list receives a duplicate e-mail generated from the sieve script of the user with vacation responder active that contains the redirect to LIST(a)domain.com. We just tried activating the duplicate extension into sieve script but the redirected e-mail has a different MSG-ID and it's not recognized as a duplicate by the server. Our dovecot conf is: /# 2.2.13: /etc/dovecot/dovecot.conf auth_mechanisms = plain login default_vsz_limit = 512 M disable_plaintext_auth = no dotlock_use_excl = no info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_fsync = never mail_location = maildir:~/Maildir mail_max_userip_connections = 50 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 ihave duplicate mmap_disable = yes passdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } passdb { args = /etc/dovecot/dovecot-ldap-archive.conf driver = ldap } plugin { sieve = file:/var/www/html/ooo/%n/script sieve_dir = /var/www/html/ooo/%n/ sieve_duplicate_default_period = 1m sieve_duplicate_max_period = 1d sieve_extensions = +vnd.dovecot.duplicate +notify +imapflags +vacation-seconds sieve_global = /etc/dovecot/sieve/ sieve_max_redirects = 10 sieve_user_log = file:/var/www/html/ooo/%n/sieve_error.log sieve_vacation_default_period = 1d sieve_vacation_max_period = 90d sieve_vacation_min_period = 5s } protocols = imap pop3 lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = vmail mode = 0660 user = vmail } user = root } service imap-login { process_limit = 200 } service lmtp { executable = lmtp -L process_min_avail = 5 unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0666 user = postfix } user = vmail } service managesieve-login { executable = /usr/lib/dovecot/managesieve-login inet_listener sieve { port = 4190 } process_min_avail = 10 service_count = 1 } service managesieve { executable = /usr/lib/dovecot/managesieve } ssl_cert = </etc/ssl/*xxxxxxxxxxxxxxxxxxxxxxxx* ssl_cipher_list = ALL:!LOW:!aNULL:!eNULL:!SSLv2:!RC4:!MD5:!DES:!EXP:!SEED:!IDEA:!3DES ssl_key = </etc/ssl/private/*xxxxxxxxxxxxxxxxxx* userdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } userdb { args = /etc/dovecot/dovecot-ldap-archive.conf driver = ldap } protocol lda { auth_socket_path = /var/run/dovecot/auth-master hostname = *xxxxxxxxxxxxxxxxx* info_log_path = /var/log/dovecot-lda.log log_path = /var/log/dovecot-lda-errors.log mail_plugins = " autocreate sieve quota" } protocol lmtp { info_log_path = /var/log/dovecot-lmtp.log log_path = /var/log/dovecot-lmtp-errors.log mail_plugins = " autocreate sieve quota" postmaster_address = postmaster@*xxxxxxxxxx* } protocol sieve { info_log_path = log_path = mail_max_userip_connections = 10 managesieve_implementation_string = dovecot managesieve_logout_format = bytes=%i/%o managesieve_max_compile_errors = 5 managesieve_max_line_length = 65536 }/ An example of user sieve script is: /require ["vnd.dovecot.duplicate","copy","fileinto","vacation-seconds"]; # rule:[Outofoffice] if true { vacation :addresses "xxxxxxx(a)domain.tld" :subject "Automatic Reply" text: / /<Text here> . ; fileinto "INBOX";/ / redirect "LIST(a)domain.com";/ /}/ Please could someone give us support on the matter?

Lmtp redirection to other backend server
by Marc Roos 11 Dec '19

11 Dec '19

I have currently a working local delivery working ok on 2 backend servers. The backend servers use slapd/nslcd/nscd for local accounts. If I enable proxy=yes in the lmtp config section, I am getting this error 'auth: Debug: passdb out: FAIL#0111#011reason=Configured passdbs don't support credentials lookups' which is obvious because I do not have a passdb. I am not sure if it is possible to get this value from the system environment eg. nslcd/nscd, without the need to configure some separate ldap lookup in dovecot? Or do I really need to configure a ldap lmtp lookup just for this host attribute? What would be an efficient solution?

What we could provide now would be the XML-Response from Solr. The corresponding search query sometimes causes this error. But Solr's answer seems to always remain the same - in my opinion this already indicates a bug of Dovecot?

The certificate are NOT self-signed but signed the legit authorities. So I'm not sure why dovecot could not establish the connections. > > > > > > > > >

OAuth2 mail client
by mizuki 10 Dec '19

10 Dec '19

Hi all, I'm wondering if there are any IMAP client software alternative to Thunderbird who can handle OAuth2 other than using gmail, yahoo etc (ex, talk to local auth provider)? Thunderbird does not seem to support well at the time being so I'm wondering what other choices we may have for our user communities. Thank you very much. Mizuki

Problem With Quota Dovecot
by Gter Marcelo 09 Dec '19

09 Dec '19

Hi Dears, I have one problem with Dovecot in My mailserver. Dovecot Quota setting is not working fine. plugin { quota = dict:User quota::file:MAILDIR/dovecot-quota quota_rule = *:storage=1GB } For example if i put the limit in 1GB, i have accounts in my mailbox with size of maildir in 3gb,4gb for exemple and if i running the command doveadm quota get -u ACCOUNT_MY_USER The user with 2GB should be return 100% or some number bigger , but return 45% used only, If i force running one force-resync, the quota-get return the size correct showing more than 100% Someone can Help me ?

[whishlist] new option for 'doveadm purge'
by Michael Grimm 09 Dec '19

09 Dec '19

Hi, I do store mail in mdbox format of 150m in size (dovecot 2.3.9). Once in a while I do experience mdbox files of smaller size, even after applying 'doveadm purge' and previous expunges by the users. like: -rw------- 1 vmail dovecot 104854595 Feb 9 2019 /var/mail/.maildirs/userX/storage/m.22 -rw------- 1 vmail dovecot 29088478 Mar 8 2019 /var/mail/.maildirs/userX/storage/m.31 -rw------- 1 vmail dovecot 98210890 Mar 20 2019 /var/mail/.maildirs/userX/storage/m.39 (Currently the counter is at file number 129.) Well, I never experienced missing mail or alike, but these "holes" in filesize irritates me, and yes, it is more or less a cosmetic issue. Nevertheless, I do sometimes want to get rid of these "holes" by backing up all mail and re-injecting the backup into a vanilla account of that user. And I used this approach when I wanted to store all mail messages in larger mdbox files; again, rather a cosmetic issue. BUT that takes a very, very long time contrary to the speed of 'doveadm purge'. Unfortunately, that command starts somewhere with more recent mdbox files and never from scratch (oldest mdbox file). Whishlist: Would it be much of an effort to implement an option like: 'doveadm purge -f' and '-f' standing for 'force' or 'from scratch' or 'from the very first message found' or 'you name it'? Thanks in advance and thanks for Dovecot and with kind regards, Michael

bash script hook lda_mailbox_autocreate for generate mail-crypt user encrypted private key with user password
by uxqex4efpu＠elude.in 09 Dec '19

09 Dec '19

What it is way most best for causing bash script run (as root) of time mailbox created (lda_mailbox_autocreate)? I use dovecot 2.3.4.1 in Debian 10. And I use of mail-crypt-plugin https://doc.dovecot.org/configuration_manual/mail_crypt_plugin/ I setup mail-crypt for requiring user encrypted EC key (mail_crypt_require_encrypted_user_key = yes). I want for passphrase encrypt EC key using client plaintext password. There is credential no stored on server. But for user with use password too bad, I concatenate user plaintext password with random salt. And then string to SHA512() hash and use as decryption key (mail_crypt_private_password) for EC private key. For above I have plugin config > mail_plugins = $mail_plugins mail_crypt > plugin { > mail_crypt_curve = secp256k1 > mail_crypt_require_encrypted_user_key = yes > mail_crypt_save_version = 2 > } And for returning userdb_mail_crypt_private_password, I have sql query > password_query = SELECT username, password, \ > SHA2( CONCAT('%w',salt), 512 ) AS userdb_mail_crypt_private_password \ > FROM virtual_users WHERE username='%u'; But how I generate key of user automatically? Note for generating key of user, I need user password plaintext. I never save plaintext password of user of the server. Also user of note creates in PHP of web of the server. And for security I do not allow PHP exec shell (php.ini disabled_functions). Definitely not leaving PHP doveadm access! For solving subject to generate user key encrypted, I do imap of call of the service 'imap-postlogin' the service likes document "Post-login scripting' write https://doc.dovecot.org/admin_manual/post_login_scripting/ And 'imap-postlogin' execute my custom script with 'script-login' binary https://github.com/dovecot/core/blob/8606e1abb90a1c91357b84bf547a89564d0535… Here it is config for above > service imap { > executable = imap imap-postlogin > } > service imap-postlogin { > executable = script-login /usr/local/bin/generateKeys.sh > unix_listener imap-postlogin { > } > } And generateKeys.sh it is script simple for generating keys with sha256() hash product mysql. Variable of note ${MAIL_CRYPT_PRIVATE_PASSWORD} automatically put of 'userdb_mail_crypt_private_password' return of mysql field of query when documented https://doc.dovecot.org/admin_manual/post_login_scripting/running-surroundi… > Fields returned by userdb lookup with their keys uppercased > (e.g. if userdb returned home, it's stored in HOME). Here generatekeys.sh > #!/bin/bash > if [ `/usr/bin/doveadm mailbox cryptokey list -u "${USER}" -U > /dev/null | wc -l` -lt 2 ]; then > /usr/bin/doveadm -o "plugin/mail_crypt_private_password=${MAIL_CRYPT_PRIVATE_PASSWORD}" mailbox cryptokey generate -u "${USER}" -U > /dev/null > fi > exec "$@" This work! But I want more good. By why execute each login? Possible has generateKeys.sh execute in the times only of dovecot create mailbox (lda_mailbox_autocreate) instead?

Execute a script from dovecot when authentication fails
by nb 09 Dec '19

09 Dec '19

Hello, My name is Noury, and I’m new here. I’ve been using dovecot IMAP for years, but I want to do now some extra things. I want to call a script from within dovecot, to build a suspicious IP addresses list when authentication fails. I have tried the PostLoginScripting technic. It works fine but it doesn’t suit my needs. The script executes only after a successful login. I want to execute my script only when auth fails. If I can execute a script and check into it if auth failed, I would be nice too. A kind of « PreLoginScript" Is there a way to achieve this? I’m reading now auth.log file, but I would like to have a realtime processing. Thanks in advance. Noury

Shared namespace is empty after migration to new Dovecot installation
by Peter Reinhold 09 Dec '19

09 Dec '19

Hi all, I've used most of this weekend finalizing my migration from an old server running Dovecot 2.2.22 to a brand new installation running 2.3.8. In general, the migration was painless, everything just clicked, but checking up on the finer details post migration i've found out that user shared folders does not seem to work anymore, and I simply can't get it to work. The setups are more or less identical, biggest change is probably the addition of a Solr search index, and i've done very little changes in the configuration files. The acl_shared_dict file is being created and updated when I share a folder In the user thats sharing the folder, the dovecot-acl and dovecot-acl-list files are created and look the same. But, the user that should be reading the shared folder can not see it, the Shared namespace is simply empty, which it is not on the old installation, and namespace setup is identical across the two servers. (Except for the CaSiNg of the location of the index and indexpvt) Logging in and doing an IMAP command : A1 LIST "Shared/" "*" yields this on the old server. (I've replaced the sharing users e-mail to user(a)sharer.dk and the reading users to user(a)reader.dk) A1 LIST "Shared/" "*" * LIST (\HasNoChildren) "/" Shared/user(a)sharer.dk A1 OK List completed (0.000 + 0.000 secs). and this on the new A1 LIST "Shared/" "*" A1 OK List completed (0.006 + 0.000 + 0.005 secs). Log output from the new server below (i've only included the events happening during the LIST account) -- New, non-working log start -- Namespace : type=shared, prefix=Shared/%u/, sep=/, inbox=no, hidden=no, list=children, subscriptions=no location=maildir:/data/mail/%d/%n/maildir:INDEX=~/maildir/shared/%u:INDEXPVT:~/maildir/shared/%u shared: root=/var/run/dovecot, index=, indexpvt=, control=, inbox=, alt= fts: Indexes disabled for namespace 'Shared/%u/' acl: initializing backend with data: vfile acl: acl username = user(a)reader.dk acl: owner = 0 acl vfile: Global ACLs disabled acl vfile: file /data/mail/reader.dk/user/maildir/dovecot-acl not found acl vfile: file /data/mail/reader.dk/user/maildir/.Junk/dovecot-acl not found acl vfile: file /data/mail/reader.dk/user/maildir/.Trash/dovecot-acl not found acl vfile: file /data/mail/reader.dk/user/maildir/.Sent/dovecot-acl not found auth-master: userdb lookup(user(a)sharer.dk): Started userdb lookup auth-master: conn unix:/var/run/dovecot/auth-userdb: Connecting auth-master: conn unix:/var/run/dovecot/auth-userdb (pid=1636,uid=0): Client connected (fd=16) auth-master: userdb lookup(user(a)sharer.dk): auth USER input: user(a)sharer.dk uid=120 gid=129 home=/data/mail/sharer.dk/user auth-master: userdb lookup(user(a)sharer.dk): Finished userdb lookup (username=user(a)sharer.dk uid=120 gid=129 home=/data/mail/sharer.dk/user) Namespace Shared/: Using permissions from : mode=0700 gid=default -- New, non-working log end -- and here from the old, working installation -- Old, working log start -- Namespace : type=shared, prefix=Shared/%u/, sep=/, inbox=no, hidden=no, list=children, subscriptions=no location=maildir:/data/mail/%d/%n/maildir:INDEX=~/Maildir/shared/%u:INDEXPVT=~/Maildir/shared/%u shared: root=/var/run/dovecot, index=, indexpvt=, control=, inbox=, alt= acl: initializing backend with data: vfile acl: acl username = user(a)reader.dk acl: owner = 0 acl vfile: Global ACLs disabled auth input: user(a)sharer.dk uid=118 gid=126 home=/data/mail/sharer.dk/user namespace/default/inbox=yes maildir++: root=/data/mail/sharer.dk/user/maildir, index=/data/mail/sharer.dk/user/Maildir/shared/user(a)sharer.dk, indexpvt=/data/mail/sharer.dk/user/Maildir/shared/user(a)sharer.dk, control=, inbox=/data/mail/sharer.dk/user/maildir, alt= acl: initializing backend with data: vfile acl: acl username = user(a)sharer.dk acl: owner = 1 acl vfile: Global ACLs disabled maildir++: root=/data/mail/sharer.dk/user/maildir, index=/data/mail/reader.dk/user/Maildir/shared/user(a)sharer.dk, indexpvt=/data/mail/reader.dk/user/Maildir/shared/user(a)sharer.dk, control=, inbox=/data/mail/sharer.dk/user/maildir, alt= acl: initializing backend with data: vfile acl: acl username = user(a)reader.dk acl: owner = 0 acl vfile: Global ACLs disabled acl vfile: reading file /data/mail/sharer.dk/user/maildir/dovecot-acl acl: Mailbox not in dovecot-acl-list: Shared/user(a)sharer.dk/Junk acl: Mailbox not in dovecot-acl-list: Shared/user(a)sharer.dk/Trash acl: Mailbox not in dovecot-acl-list: Shared/user(a)sharer.dk/Sent acl: Mailbox not in dovecot-acl-list: Shared/user(a)sharer.dk/Drafts acl: Mailbox not in dovecot-acl-list: Shared/user(a)sharer.dk/Junk acl: Mailbox not in dovecot-acl-list: Shared/user(a)sharer.dk/Trash acl: Mailbox not in dovecot-acl-list: Shared/user(a)sharer.dk/Sent acl: Mailbox not in dovecot-acl-list: Shared/user(a)sharer.dk/Drafts -- Old, working log end -- The two logs are quite different, the new one seems to do user lookups via the auth socket, which the old one does not, and then just stops there.

director option
by soumitri＠iitk.ac.in 09 Dec '19

09 Dec '19

Hi, I think option-2 below seems better or am I missing something with director concept. 1. As director and back-end in same server (broken) not recommended, I need minimum 4 servers (2 for director, 2 back-end IMAP). Indexes and mail must be in NFS shared storage(not optimal), as a user may land on any of the back-end servers (assuming no static mapping of user from pass DB). 2) Proxy_may in passDB (static mapping of users to servers makes balancing little partial but can be admin optimized) can achieve the above setup with 2 servers without director. Here indexes can be on their local disk (efficient) and mail on shared storage (NFS). Both case I can use RR DNS to get users IMAP traffic to front end. Any guidance on this is appreciated. -- Sincerely, Soumitri Mishra

Adding Size information to Maildir files
by ＠lbutlr 08 Dec '19

08 Dec '19

I searched on this, but found information only for very very old dovecot versions, and those answers didn’t quite cover what I am asking. All my current mail has the ",S=51489,W=52449:” style tag in the Maildir filename, but I have many messages in Archive mailboxes that have no size information. Is it possible to automate adding the size info to the files without mucking up the mail in various ways? (In my mail spool its about 10:1 with nearly 400,000 mails tagged with a size field and just over 40,000 not tagged, so it is definitely not something I want to do by hand). -- You know, Rick, I have many a friend in Casablanca, but somehow, just because you despise me, you are the only one I trust.

SEARCH=INTHREAD not announced in capabilities
by kael 08 Dec '19

08 Dec '19

Hello, Looking at the SEARCH=INTHREAD extension, Dovecot implements it but the server doesn't announce the extension in its capabilities (at least testing with imap://dovecot.org or looking at https://github.com/dovecot/core/blob/169b1ff42a28cdf2768391d20e8fef13aeae54… ) It does work though: a UID SEARCH INTHREAD REFS HEADER subject "Re: bash script" * SEARCH 106075 106076 106084 a OK Search completed (1.047 + 0.000 + 1.046 secs). I'd have thought that announcing THREAD=REFS would imply SEARCH=INTHREAD, but testing with Fastmail only the former is implemented. Looks like a bug in Dovecot as the client can't discover the SEARCH=INTHREAD capability. Cheers. -- kael

Accessing the -a and -d from dovecot-lda
by Aristedes Maniatis 08 Dec '19

08 Dec '19

I've got exim set up to deliver like this: command = /usr/local/libexec/dovecot/dovecot-lda -a $original_local_part@$original_domain -d $local_part@$domain -f $sender_address If an email to is bob+sales(a)ish.com.au then we should have "-a bob+sales(a)subdomain.ish.com.au -d bob(a)ish.com.au". Now in dovecot, only bob(a)ish.com.au is a real user but I want to be able to use both addresses in different places. For LDAP lookup I need to reference bob(a)ish.com.au. But in sieve, I need to see the original address with plus notation. However, dovecot appears to get the "-a" address into %u and the "-d" address can't be accessed. https://doc.dovecot.org/configuration_manual/config_file/config_variables/ Is what is the point of dovecot-lda having both -a and -d options? Can I get at both bits of data? Thanks Ari

ssl_min_protocol = TLSv1.3 does not work
by Laurens Post 08 Dec '19

08 Dec '19

Hi all, I'm trying to set up my server with support for TLS 1.3 only, but that does not seem to be supported. First off, TLS 1.3 itself does work fine, so it's not the config or ssl library, and 1.3-only works fine with Postfix. The problem is only in disabling TLS 1.2 for Dovecot. On connection, I'm getting an error that 1.3 is an "Unknown ssl_min_protocol setting". Reading the source code, it seems that `openssl_min_protocol_to_options` in `src/lib-ssl-iostream/iostream-openssl-common.c` is simply missing an entry like { SSL_TXT_TLSV1_3, TLS1_3_VERSION, SSL_OP_NO_SSLv3 | SSL_OP_NO_TLSv1 | SSL_OP_NO_TLSv1_1 | SSL_OP_NO_TLSv1_2 } Is this a bug, something intentional, or has it simply not been added yet because nobody has been crazy enough to ask for it? Kind regards, Laurens

Dovecot 2.3.8 - How to force index creation for user/mailbox?
by Tomek Lutelmowski 08 Dec '19

08 Dec '19

Hello, I'm using maildirs, and I have problems with big mailboxes (~ 20000 emails, 30-50GB) - sometimes access to such mailbox takes very long (~10 minutes), I would like to be able to create index for mailbox in background, but I couldn't find any way to do it. So far I tried: *doveadm -D -vvv index -u user 'Folder' * But even if this folder have no dovecot.index* files - I always get: doveadm(user): Info: Wersje robocze: Cache is already up to date It seems that doveadm doesn't actually checks if the index is present. The index is created only when I log with IMAP client and check the folder. So i tried: *doveadm mailbox cache purge -u user 'Folder' * No joy either: doveadm(user): Error: Cache is unusable And command below doesn't actually do anything to index: *doveadm -vvv force-resync -u user 'Folder'* Is there any way to use doveadm tool to create/fix index? Shouldn't the index be updated on each email arrival? Cheers, TomekL
