director_username_hash = %d and doveadm director map
by Ralf Becker 30 Nov '20

30 Nov '20

Our directors hash by domain (director_username_hash = %d), as some of our users share folders with other users of the same domain. We now started using director tags to map domains to their backends. Unfortunately doveadm director map seems no to work with director_username_hash = %d user hash mail server ip expire time <unknown> 432784257 10.44.88.1 2020-11-23 13:10:55 <unknown> 4244233328 10.44.88.1 2020-11-23 13:13:55 <unknown> 1913982503 10.44.88.1 2020-11-23 13:15:40 How can I check to which backend / IP a domain is maped, aka how is that hash calculated? doveadm director move seems also not to do anything meaningful for %d, or at least I have not found out how to use it to move a domain to a different backend.

A probably dumb question, but I'm stumped
by Christy S 30 Nov '20

30 Nov '20

Hi folks, I'm stumped on an error we're getting in dovecot after upgrading ubuntu. I will say up front that I'm far from a linux expert. I'm helping my husband by managing a virtual private server to handle his domain, including its email. We set this up two years ago and once I finally got the mail working, it's been humming along just fine since, until two days ago when I performed the ubuntu upgrade. Now, when we try to send mail through his domain thunderbird gives this error: Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. Note that it says this, but the mail isn't actually sent at all. We are using SSL and have been since the beginning which might be part of our problem, but I'm not positive. A google search suggested adding two lines to the 10-ssl.conf file. ssl_dh = </usr/share/dovecot/dh.pem ssl_cipher_list = HIGH:!DH:!aNULL I did both of these things and restarted the server completely, but no luck. looking in /var/log/mail.err I see this. Nov 29 14:08:56 kylesmith-music dovecot: imap-login: Error: Failed to initialize SSL server context: Can't load SSL cert ificate: error:140AB18F:SSL routines:SSL_CTX_use_certificate:ee key too small: user=<>, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx, session=<t4qrdkS1kPNLFhL4> What's interesting is that last line only showed up after I added the two lines to the config file. My guess is I need to do something with SSL, update it maybe? But I don't want to go fiddling around purely on a guess and potentially break things even more. So, any of you much more linux familiar types want to point me in the right direction? Thanks! Christy

Repo for ubuntu focal 20.04 LTS
by Sébastien Riccio 27 Nov '20

27 Nov '20

Hello Dovecot, As the new ubuntu LTS 20.04 seems to be out, I would like to ask if there are any plans to add a repo like it already exists for 18.04 LTS. We planned to upgrade our 18.04 LTS boxes to 20.04. It has it’s own dovecot packages (2.3.7 at the time of writing this), but I would prefer we use your repositories like we do with 18.04. Kind regards, Sébastien

Dovecot alternatives with good i18n support?
by David Bürgin 26 Nov '20

26 Nov '20

Hello! I’m interested in exploring alternative IMAP servers that have good support for internationalised email, such as support for SMTPUTF8, IDN mail domains, Unicode local-part, etc. etc. If you used to use Dovecot, and found an alternative that does such things well, I would very much like to hear it. Thank you, -- David

Panic: file istream-seekable.c: line 226
by Eric Mauger 26 Nov '20

26 Nov '20

Hi, I have a lot of Panic in my logs. They happen almost every day and never on the same user. When it happens, the mail is not distributed (it's always lda). I discovered it because my Sympa server had a lot of users in error. The last error (below) was a local user sending a mail to 10 users : 3 of them never get the email. I've looked into my logs and discovered it started after the upgrade from 2.2.27 to 2.3.4 in february. I'm on Debian. This week, I installed the dovecot repo and upgraded to the very last and same thing. The error below happened after the latest upgrade. An example : Nov 25 11:33:07 mx.igf.cnrs.fr dovecot: lda(username_hidden)<4653><A3S4MuIyvl8tEgAAmSH/vg>: Panic: file istream-seekable.c: line 230 (read_from_buffer): assertion failed: (*ret_r > 0) Nov 25 11:33:07 mx.igf.cnrs.fr dovecot: lda(sebastien.granier)<4653><A3S4MuIyvl8tEgAAmSH/vg>: Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(backtrace_append+0x3d) [0x7f49a56d4eed] -> /usr/lib/dovecot/libdovecot.so.0(backtrace_get+0x1e) [0x7f49a56d500e] -> /usr/lib/dovecot/libdovecot.so.0(+0xf465b) [0x7f49a56de65b] -> /usr/lib/dovecot/libdovecot.so.0(+0xf46c1) [0x7f49a56de6c1] -> /usr/lib/dovecot/libdovecot.so.0(+0x514a6) [0x7f49a563b4a6] -> /usr/lib/dovecot/libdovecot.so.0(+0x53cfb) [0x7f49a563dcfb] -> /usr/lib/dovecot/libdovecot.so.0(+0x1074a1) [0x7f49a56f14a1] -> /usr/lib/dovecot/libdovecot.so.0(+0x1078f6) [0x7f49a56f18f6] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_stat+0x34) [0x7f49a56eaab4] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0xb1396) [0x7f49a5852396] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0xb1472) [0x7f49a5852472] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_get_physical_size+0x38) [0x7f49a57ef0c8] -> /usr/lib/dovecot/libdovecot-lda.so.0(+0x4005) [0x7f49a5907005] -> /usr/lib/dovecot/libdovecot-lda.so.0(mail_deliver_init+0x141) [0x7f49a5908101] -> /usr/lib/dovecot/deliver(main+0x879) [0x562d1c0e6f99] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xeb) [0x7f49a543e09b] -> /usr/lib/dovecot/deliver(_start+0x2a) [0x562d1c0e76ea] My configuration : dovecot -n # 2.3.11.3 (502c39af9): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.11 (6c69c917) # OS: Linux 4.19.0-9-amd64 x86_64 Debian 10.6 # Hostname: mx.igf.cnrs.fr auth_username_format = disable_plaintext_auth = no lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes mail_location = maildir:~/maildir mail_plugins = fts mail_privileged_group = mail 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 Ads { auto = subscribe } 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 = separator = . type = private } passdb { driver = pam } plugin { sieve = file:~/sieve;active=~/.dovecot.sieve sieve_after = /etc/dovecot/sieve.d } protocols = " imap sieve pop3 sieve" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } service imap-login { process_min_avail = 16 service_count = 0 } service managesieve-login { inet_listener sieve { port = 4190 } } service stats { unix_listener stats-reader { group = dovecot mode = 0666 user = root } unix_listener stats-writer { group = dovecot mode = 0666 user = root } } ssl_cert = </etc/dovecot/ssl/certs/mx_igf_cnrs_fr_with_CA.crt ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it syslog_facility = local2 userdb { driver = passwd } verbose_proctitle = yes protocol lda { mail_plugins = fts sieve syslog_facility = local2 } Thanks, -- Eric Mauger | Administrateur système et réseau IGF UMR5203 | https://www.igf.cnrs.fr

Dovecot+Solr+Tika segmentation fault
by Manuel Josupeit-Walter 25 Nov '20

25 Nov '20

Hi all, I am running a mail server for family and friends based on Dovecot and Docker. Today I made a weird observation which I must have overlooked for a long time so far because they logs were written to the journal. However, I am usually only investigating the Docker logs. It seems that some e-mail indexing leads to segfaults and it seems to be related only with Solr and Tika. I have auto-indexing turned on so sometimes the indexer-worker crashes when moving mails from one folder to the other or searching for mails otherwise. Also, if I try to manually reindex using doveadm index, the doveadm process quits with a segfault. I am always running the most recent Dovecot version, in this case 2.3.11.3, but I am not neccessarily up-to-date with Solr or Tika. I am on Solr Version 7.4 and Tika 1.24.1. On the console I am receiving Tika errors and on the Solr Webinterface I see a couple of Ealry EOFs as well. I am not a Linux expert from a dev perspective, but it seems to me that the client (Dovecot) closes the connection prematurely. Does anyone have a hint? I am happy to provide more information if required. I need to know how to collect them, though. Best, Manuel The following can be found in the journald logs during the attempt to reindex my Sent mailbox with doveadm index: Nov 24 16:59:49 server.name tika[988]: INFO tika/ (application/pdf) Nov

Dovecot authentication hangs when ldap_start_tls_s() fails for invalid certificate
by sebastiano degan 19 Nov '20

19 Nov '20

On a Debian10 I've installed postfix 3.4.14 and dovecot 2.3.4.1. I've configured multiple passdb sources and I expect that if one fails the other ones are tested. This is usually the case, except when the failure is due to an invalid certificate from the ldap server. In that case all authentication attempts from that moment on will fail. I've trimmed down the configuration as much as possible (see below), and this is the syslog output of my tests: TEST 1 - Everything is configured correctly: No output on syslog TEST 2 - Wrong hostname as a ldap server: Auth attempt 1: Nov 19 11:25:29 debian dovecot: auth: Error: LDAP /etc/dovecot/dovecot-ldap-passdb.conf.ext: ldap_start_tls_s() failed: Can't contact LDAP server Nov 19 11:25:29 debian dovecot: auth: Error: LDAP /etc/dovecot/dovecot-ldap-userdb.conf.ext: ldap_start_tls_s() failed: Can't contact LDAP server Nov 19 11:25:29 debian dovecot: auth: Error: LDAP /etc/dovecot/dovecot-ldap-passdb.conf.ext: ldap_start_tls_s() failed: Can't contact LDAP server Nov 19 11:25:35 debian dovecot: auth: Error: LDAP /etc/dovecot/dovecot-ldap-passdb.conf.ext: ldap_start_tls_s() failed: Can't contact LDAP server Auth attempt 2: Nov 19 11:25:57 debian dovecot: auth: Error: LDAP /etc/dovecot/dovecot-ldap-passdb.conf.ext: ldap_start_tls_s() failed: Can't contact LDAP server Nov 19 11:25:59 debian dovecot: auth: Error: LDAP /etc/dovecot/dovecot-ldap-passdb.conf.ext: ldap_start_tls_s() failed: Can't contact LDAP server Auth attempt 3: Nov 19 11:26:28 debian dovecot: auth: Error: LDAP /etc/dovecot/dovecot-ldap-passdb.conf.ext: ldap_start_tls_s() failed: Can't contact LDAP server Nov 19 11:26:30 debian dovecot: auth: Error: LDAP /etc/dovecot/dovecot-ldap-passdb.conf.ext: ldap_start_tls_s() failed: Can't contact LDAP server TEST 3 - Invalid certificate: Attempt 1: Nov 19 11:21:20 debian dovecot: auth: Error: LDAP /etc/dovecot/dovecot-ldap-passdb.conf.ext: ldap_start_tls_s() failed: Connect error Nov 19 11:21:20 debian dovecot: auth: Error: LDAP /etc/dovecot/dovecot-ldap-userdb.conf.ext: ldap_start_tls_s() failed: Connect error No output on other attempts...
