Dovecot Version: 2.3.2.1 Hello Mailing List, We are having a random issue in a couple of our production servers, where one of the child processes randomly dies with an out of memory error (see below): Nov 26 11:58:17 config: Fatal: pool_system_malloc(8192): Out of memory Nov 26 11:58:17 pop3-login: Fatal: Error reading configuration: read(/var/run/dovecot/config) failed: EOF Nov 26 11:58:17 config: Fatal: master: service(config): child 29696 returned error 83 (Out of memory (service config { vsz_limit=2048 MB }, you may need to increase it) - set CORE_OUTOFMEM=1 environment to get core dump) We only use dovecot for internal application POP3 mail access from a mailbox, and there is under 10 connecting applications. Have have gradually increased the vsz_limit from the default of 256mb up to 2GB now. Is there anything else that should/could be changed instead of continuing to through memory at it? # dovecot -n # 2.3.2.1 (0719df592): /etc/dovecot/dovecot.conf # OS: Linux 3.10.0-862.11.6.el7.x86_64 x86_64 CentOS Linux release 7.5.1804 (Core) # Hostname: <Internal host name here, removed> doveconf: Warning: please set ssl_dh=</etc/dovecot/dh.pem doveconf: Warning: You can generate it with: dd if=/var/lib/dovecot/ssl-parameters.dat bs=1 skip=88 | openssl dhparam -inform der > /etc/dovecot/dh.pem auth_cache_size = 10 M auth_verbose = yes base_dir = /var/run/dovecot/ default_vsz_limit = 2 G instance_name = EMX Pop Mailstore listen = <Internal ethernet Name Here, removed> log_path = /var/log/dovecot-echo.log login_greeting = Pop3 MailServer Ready. login_trusted_networks = <IP Addresses Here, removed> mail_location = maildir:~/Maildir 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 = cache_key=%u driver = pam } protocols = pop3 ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { driver = passwd } verbose_ssl = yes Thanks, Kevin

Hello list. I am running dovecot v2.2.13 on debian 8.8; I tried to add a "address =" statement for only localhost and one private IP, but then I got a complaint from system: dovecot[20515]: Error: systemd listens on port 143, but it's not configured in Dovecot. Closing. What is the proper way to resolve this? TIA & Regards, Dudi

LDAP login fails after LDAP server restart
by Dag Nygren 25 Nov '18

25 Nov '18

Hi! Just udated my Fedora dovecot to version 2.2.36 and found that after the update dovecot will fail all LDAP logins after slapd has been restarted during the logrotate. Restarting dovecot fixes the problem. Is there a bug preventing dovecot to reopen the LDAP session when it fails? Best Dag

Installing on Mojave, with Homebrew and mysql
by James Brown 25 Nov '18

25 Nov '18

I’m using Homebrew to install Dovecot on Mojave, but have to modify the formula to add ‘--with-mysql’. Unfortunately compiling always fails with: checking for mysql_config... NO checking for mysql_init in -lmysqlclient... no configure: error: Can't build with MySQL support: libmysqlclient not found I added: ENV['LD']="-L/usr/local/opt/mysql(a)5.7/lib" to the ‘def install’ section of the formula, but it still fails. config.log shows: … KRB5_LIBS='' LD='-L/usr/local/opt/mysql(a)5.7/lib/' LDAP_LIBS=‘' … And mysqlclient is here: $ locate mysqlclient /usr/local/Cellar/mysql(a)5.7/5.7.24/lib/libmysqlclient.20.dylib /usr/local/Cellar/mysql(a)5.7/5.7.24/lib/libmysqlclient.a /usr/local/Cellar/mysql(a)5.7/5.7.24/lib/libmysqlclient.dylib /usr/local/Cellar/mysql(a)5.7/5.7.24/lib/pkgconfig/mysqlclient.pc I changed the formula to: ENV['LD']="-L/usr/local/Cellar/mysql(a)5.7/5.7.xn--24/lib/-236c And still get the same thing. Any suggestions? Thanks, James.

Is there any information on using dovecot on Mojave? I have been using Mac OS Server for a few years and looking for the preferred way to move to Mojave since dovecot and postfix admin support has been dropped by Apple.

Testing validity of Dovecot config in a script
by Ralph Seichter 24 Nov '18

24 Nov '18

While trying to determine a given configuration is valid from within a script, I found that the following works with Dovecot version 2.3.2.1: #!/usr/bin/env bash doveconf -n >/dev/null || echo "Config is invalid" However, the return code is not documented in the doveconf manual page, and I wonder if the observed behaviour can be relied on? Is this the recommended method to test configuration validity? Personally, I'd like to have a dedicated call available. Something like # Proposal: "-t" for "test config" doveconf -t [-c config-file] with documented return codes would be ideal. -Ralph

Problems after upgrading to 2.3.2.1
by Joel Dahl 23 Nov '18

23 Nov '18

Hi, I've just upgraded dovecot from 2.2.35 to 2.3.2.1 on my mail server and noticed something odd. My mail clients (mutt and Apple mail) both stopped seeing new mail in my mailboxes. For example, ~/Maildir/mailinglist1/new has 5 new mails. In mutt, vieweing the list of mailboxes mutt reports 0 new mail for "mailinglist1". Opening up the actual mailbox in mutt reveals the 5 new mails. Going back to the list of mailboxes, mutt now correctly reports 5 unread mails. Waiting a few hours, and about 10 new mails have arrived, but mutt still says 5 unread. This is the same for every mailbox. As a test I deleted the index files for a specific mailbox and restarted dovecot. But it didn't help. I use procmail to deliver my mail into the Maildir folders, if that matters. Any ideas? I haven't changed my dovecot configuration in a long time, except for adding ssl_dh after the upgrade. My config is below: auth_mechanisms = plain login imap_client_workarounds = delay-newmail tb-extra-mailbox-sep tb-lsub-flags info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_location = maildir:~/Maildir mail_privileged_group = mail maildir_very_dirty_syncs = yes passdb { args = session=yes dovecot driver = pam } protocols = imap service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } ssl = required ssl_cert = </path/to/cert.pem ssl_dh = # hidden ssl_key = # hidden userdb { driver = passwd } -- Joel

doveadm dsync-server doesn't use user parameter?
by Harald Leithner 23 Nov '18

23 Nov '18

Hi, I tried to migrate my dovecot 2.2 to a new server with a other storage configuration and dovecot 2.3. New (and old) Server uses mysql for user information I use the following storage settings mail_home = /storage1/vmail/%{userdb:path} mail_location = mdbox:/storage1/fast/%{userdb:path}:FULLDIRNAME=iTrNiCs-DBOx-mAiLs:INDEX=/storage1/indexes/vmail/%{userdb:path}:ALT=/storage1/slow/%{userdb:path}:VOLATILEDIR=/tmp/%{userdb:path} userdb:path is generated by the mysql query and ends in something like "2000/6" SQL: CONCAT(u.idAccount, '/', u.idUser) AS userdb_path If I login with imap dovecot is creating the INBOX on the correct path /storage1/fast/2000/6/mailboxes/INBOX btw. it creates a link to dbox-alt-root but without creating the target directory is this expected? Now if I start doveadm backup -u <username> remote:mailstore2 it ignores it seams that dsync-server doesn't make a database query and doesn't use the userdb_path field. It only uses /storage1/fast/mailboxes/INBOX as path. Is this a problem with my configuration? thx --- doveconf -n # 2.3.3 (dcead646b): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.3 (f018bbab) # OS: Linux 4.15.18-7-pve x86_64 Debian 9.6 zfs # Hostname: mailstore2 auth_cache_negative_ttl = 1 secs auth_cache_size = 10 M auth_cache_ttl = 1 secs auth_master_user_separator = * auth_mechanisms = PLAIN LOGIN APOP auth_verbose = yes default_client_limit = 600 default_vsz_limit = 512 M dict { lastlogin = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext sqlacl = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no first_valid_gid = 1001 first_valid_uid = 1001 hostname = mailstore2 imap_hibernate_timeout = 1 mins imap_id_log = * imap_id_send = * imap_idle_notify_interval = 10 mins imap_logout_format = bytes=%i/%o instance_name = mailstore2 last_valid_gid = 1001 last_valid_uid = 1001 lda_original_recipient_header = X-LDA-Original-To lmtp_rcpt_check_quota = yes login_greeting = ITronic Mail Store login_trusted_networks = 172.22.14.0/24 mail_cache_min_mail_count = 5 mail_gid = vmail mail_home = /storage1/vmail/%{userdb:path} mail_location = mdbox:/storage1/fast/%{userdb:path}:FULLDIRNAME=iTrNiCs-DBOx-mAiLs:INDEX=/storage1/indexes/vmail/%{userdb:path}:ALT=/storage1/slow/%{userdb:path}:VOLATILEDIR=/tmp/%{userdb:path} mail_plugins = lazy_expunge acl quota mail_log notify mail_prefetch_count = 100 mail_server_admin = mailto:postmaster@example.com mail_server_comment = Mail System mail_shared_explicit_inbox = yes mail_uid = vmail 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 vacation-seconds mdbox_preallocate_space = yes namespace { hidden = yes list = no location = mdbox:/storage1/fast/%{userdb:path}:MAILBOXDIR=expunged:LISTINDEX=expunged.list.index:FULLDIRNAME=iTrNiCs-DBOx-mAiLs:INDEX=/storage1/indexes/vmail/%{userdb:path}:ALT=/storage1/slow/%{userdb:path}:VOLATILEDIR=/tmp/%{userdb:path} prefix = "#EXPUNGED/" subscriptions = no type = private } namespace { list = children location = mdbox:%%h/mdbox prefix = "#Users/%%u/" separator = / subscriptions = yes type = shared } namespace inbox { hidden = no inbox = yes location = mailbox Archvie { special_use = \Archive } mailbox Drafts { special_use = \Drafts } mailbox Sent { special_use = \Sent } mailbox Spam { special_use = \Junk } mailbox Trash { special_use = \Trash } prefix = separator = / subscriptions = yes type = private } passdb { args = /etc/dovecot/master-users driver = passwd-file master = yes result_success = continue-ok } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile acl_shared_dict = proxy::sqlacl last_login_dict = proxy::lastlogin last_login_key = #

Re: LDAP stored quota
by Aki Tuomi 23 Nov '18

23 Nov '18

I noticed that you sent replies to me directly... Anyways, seems the problem was that the LDAP user_attrs is missing commas, and the mailRoutingAddress is used wrong, so the correct syntax would be: user_attrs = \ mailRoutingAddress=user, \ =uid=vmail, \ =gid=mail, \ =home=/var/mail/%d/%n, \ =quota_rule=*:bytes=%{ldap:departmentNumber} Aki > On 22 November 2018 at 15:29 Vincent Seynhaeve <vlamsdoem(a)gmail.com> wrote: > > > doveadm quota recalc -u test doesn't give anything. > Bellow the ouput of the `doveconf -n` and `doveadm user test` > > doveconf -n > # 2.2.10: /etc/dovecot/dovecot.conf > # OS: Linux 3.10.0-862.11.6.el7.x86_64 x86_64 CentOS Linux release 7.5.1804 > (Core) xfs > auth_debug = yes > auth_mechanisms = plain login > auth_verbose = yes > mail_debug = yes > mail_gid = mail > mail_home = /var/mail/%d/%n > mail_location = maildir:/var/mail/%d/%n/Maildir > mail_plugins = " quota" > mail_uid = vmail > 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 > mbox_write_locks = fcntl > 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 { > quota = maildir:User quota > quota_grace = 10%% > quota_rule2 = Trash:storage=+100M > quota_status_nouser = DUNNO > quota_status_overquota = 552 5.2.2 Mailbox is full > quota_status_success = DUNNO > sieve = ~/.dovecot.sieve > sieve_dir = ~/sieve > } > protocols = imap pop3 lmtp sieve > service auth { > unix_listener /var/spool/postfix/private/auth { > group = postfix > mode = 0666 > user = postfix > } > unix_listener auth-userdb { > group = mail > mode = 0600 > user = vmail > } > } > service imap-login { > inet_listener imap { > port = 0 > } > } > service managesieve-login { > inet_listener sieve { > port = 4190 > } > } > service pop3-login { > inet_listener pop3 { > port = 0 > } > inet_listener pop3s { > port = 0 > } > } > ssl = required > ssl_cert = </etc/pki/tls/certs/imap.example.com.crt > ssl_key = </etc/pki/tls/private/imap.example.com.key > userdb { > args = /etc/dovecot/dovecot-ldap.conf.ext > driver = ldap > } > protocol lda { > mail_plugins = " quota sieve" > } > protocol imap { > mail_plugins = " quota imap_quota" > } > > > > > doveadm user test > field value > uid vmail > gid mail > home /var/mail//test > mail maildir:/var/mail//test/Maildir > mailRoutingAddress user =uid=vmail =gid=mail =home=/var/mail//test > =quota_rule=*:bytes=1M > > > Le jeu. 22 nov. 2018 à 14:18, Aki Tuomi <aki.tuomi(a)open-xchange.com> a > écrit : > > > Can you provide output of `doveconf -n` and `doveadm user test`?
