Haproxy and Dovecot auth
by Giuseppe Civitella 26 Oct '15

26 Oct '15

Hi all, I'd like to use Haproxy to balance an auth service on a couple of Dovecot directors to have a redundant sasl service for my Postfix instances. While I configure the Postfixes to use, as smtpd_sasl_path, a direct connection to one of the directors I notice no errors. When I redirect the smtpd_sasl_path through an Haproxy balanced connection, I receive an error the first time I try to sen an email. The error is: SASL PLAIN authentication failed: Connection lost to authentication server If then I send more emails I receive no errors. If I do not send emails for a few minutes, the error appears again. The relevant Haproxy configuration is the following: listen auth *:12345 mode tcp balance source log global option tcplog option log-health-checks stick-table type ip size 200k expire 30m stick on src default-server inter 1000 fall 3 rise 1 server dovecot-director01 dovecot-director01:12345 check Do anyone have an idea about what it's missing? Thanks a lot Giuseppe -- Giuseppe Civitella gcivitella(a)entermail.it

Memory leak or misconfiguration: Repeated allocation of very large block
by Sebastian Wolfgarten 25 Oct '15

25 Oct '15

Dear all, I am using Dovecot 2.2.19 and I keep on getting the following warnings in my mail.log file on FreeBSD 10: Oct 24 10:45:28 server1 dovecot: imap: Error: GC Warning: Repeated allocation of very large block (appr. size 20480): Oct 24 10:45:28 server1 dovecot: imap: Error: May lead to memory leak and poor performance. I am wondering whether this is a configuration issue (i.e. a mistake in my current config) or whether I am hitting a bug. What’s the best way of figuring this one out? I tried increasing the verbosity of the logs but it did not really provide me with further information. Any ideas? Here is my config: -- [root@server1 ~]# dovecot -n # 2.2.19: /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.4.9 (357ac0a0e68b+) # OS: FreeBSD 10.1-RELEASE amd64 zfs auth_cache_size = 50 M auth_mechanisms = plain login default_vsz_limit = 512 M disable_plaintext_auth = no first_valid_uid = 1008 last_valid_uid = 1008 login_greeting = Ready. mail_gid = 1008 mail_location = maildir:/var/mail/vdomains/%d/%n mail_max_keyword_length = 128 mail_max_userip_connections = 20 mail_uid = 1008 maildir_stat_dirs = yes 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 passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf driver = sql } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = sebastian(a)wolfgarten.com protocols = imap pop3 lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { group = vmail mode = 0666 user = vmail } user = $default_internal_user } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } process_min_avail = 3 service_count = 0 vsz_limit = 512 M } service imap-postlogin { executable = script-login /usr/local/etc/popafter.sh user = $default_internal_user } service imap { executable = imap imap-postlogin process_limit = 1024 vsz_limit = 512 M } service lmtp { unix_listener lmtp { mode = 0666 } } service managesieve-login { inet_listener sieve { port = 4190 } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service pop3-postlogin { executable = script-login /usr/local/etc/popafter.sh user = $default_internal_user } service pop3 { executable = pop3 pop3-postlogin process_limit = 1024 } ssl_ca = </etc/postfix/ca.pem ssl_cert = </etc/postfix/server1.wolfgarten.com.crt.chain ssl_cipher_list = ALL:!LOW:!ADH:!SSLv2:SSLv3:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!SRP:!DSS:!RC4:+HIGH:+MEDIUM ssl_key = </etc/postfix/server1.wolfgarten.com.key ssl_protocols = !SSLv2 !SSLv3 userdb { driver = prefetch } userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf driver = sql } userdb { driver = prefetch } userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf driver = sql } protocol lda { mail_plugins = " sieve" } -- Many thanks.

Notify plugin doesn't send mailbox_create notifications
by Lukas Mika 25 Oct '15

25 Oct '15

Hi there, I'm running dovecot 2.2.13 on my debian jessie server. When installing my own dovecot plugin, I noticed that there are no notifications coming from the notify plugin. I checked back with the mail_log plugin, but also this plugin doesn't log any notifications when a new mailbox is created; the mail is saved to the new inbox never the less. I ran dovecot 2.2.9 before on my Ubuntu Trusty (14.04) server, where with the same settings the plugins worked. Can you reproduce this issue and does anybody know a fix to this? Here are the relevant bits of my config: 20-lmtp.conf: protocol lmtp { mail_plugins). mail_plugins = $mail_plugins sieve mail_log notify } 10-logging.conf ... plugin { mail_log_events = mailbox_create mail_log_fields = uid box } ... Cheers

Question about dovecot replication
by Urban Loesch 25 Oct '15

25 Oct '15

Hi, last week I installed 2 servers with two dovecot nodes and replication in active/active mode located in different datacenters. Based on the howto from wiki "http://wiki2.dovecot.org/Replication" it works great. According to the wiki it is recomended to run "doveadm purge" on both systems continously, because "doveadm purge" will not be replicated by the replication service. No problem so far. But I have one doubt: is it also reccmended (for keeping maildata in sync) to run "doveadm replicator replicate '*'" continously on both nodes? Or is it enough on only one node? Or should I run "doveadm sync -A tcp:anotherhost.example.com" in regular intervalls? Perhaps once a day on both nodes? Thanks Urban Loesch

help filtering messages
by James 23 Oct '15

23 Oct '15

Hello, I'm attempting to use sieve-filter on a local mailbox. I've defined mail_location as follows: % grep mail_location /etc/dovecot/conf.d/10-mail.conf mail_location = maildir:~/Mail I have a large number of mailboxes / mail in ~/Mail: ~ % find Mail | wc -l 63158 There are definitely a few messages in INBOX: ~ % find Mail/INBOX/cur | wc -l 5 I must admit, I'm completely new to sieve and have just begun experimenting with it. Based on a super helpful blog post[1], I quick set up the following ~/.sieve: % cat ~/.sieve require ["fileinto"]; # rule:[TEST] if header :contains "Subject" "Test Email" { fileinto "TEST"; stop; } As mentioned, there are numerous emails in INBOX. This email is located in ~/Mail/INBOX/cur/<blah> and, for verbosity (and to ensure I'm not making a foolish mistake), I've displayed it here: From: Test Account <test(a)test.com> To: "Me" <me(a)test.com> Subject: Test Email Date: Mon, 19 Oct 2015 14:55:06 +0000 This is a test email. Looking at the sieve filter recipe and email message, it appears that I should have a match, no? sieve-filter appears to disagree: % sieve-filter -C ~/.sieve INBOX sieve-filter(test_user): Debug: Effective uid=1000, gid=1000, home=/home/test_user sieve-filter(test_user): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Mail sieve-filter(test_user): Debug: maildir++: root=/home/test_user/Mail, index=, indexpvt=, control=, inbox=/home/test_user/Mail, alt= Thinking this was because sieve will only filter on new messages, I moved the file from cur to new. No change. Any thoughts on why this may be happening? Thanks! 1 https://mebsd.com/configure-freebsd-servers/dovecot-pigeonhole-sieve-filter…

Hibernation disabled when mailbox selected
by Joseph Tam 20 Oct '15

20 Oct '15

After setting imap_hibernate_timeout to 60s, I could not find any hibernated connections after a few hours. I tested hibernation and made an observation: IDLE'd imap sessions only hibernate if they don't have a mailbox SELECT'd, otherwise they never hibernate. Is this the way it's supposed to work?

Hello everyone, For this installation I am using passdb against AD, userdb with MySQL and nfs storage but using simultaneously the vfile acl backend and the shared mailbox dictionary I get the following panic: Oct 19 12:34:51 server dovecot: imap-login: Login: user=<user04>, method=PLAIN, rip=10.112.99.52, lip=10.113.63.50, mpid=7538, session=<NKsDsnIiU7YKcGM0> Oct 19 12:34:51 server dovecot: dict(7540): Panic: file dict-sql.c: line 670 (sql_dict_iterate): assertion failed: ((ctx->flags & DICT_ITERATE_FLAG_ASYNC) != 0) Oct 19 12:34:51 server dovecot: dict(7540): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0() [0x31826800ca] -> /usr/lib64/dovecot/libdovecot.so.0() [0x3182680136] -> /usr/lib64/dovecot/libdovecot.so.0() [0x31826299ea] -> dovecot-mailbox/dict() [0x406abc] -> dovecot-mailbox/dict() [0x4047aa] -> dovecot-mailbox/dict() [0x404f32] -> dovecot-mailbox/dict(dict_command_input+0xab) [0x4050bb] -> dovecot-mailbox/dict() [0x40425b] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x5b) [0x3182692deb] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0xb7) [0x31826943c7] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x25) [0x3182692e95] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x3182693038] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x318262e953] -> dovecot-mailbox/dict(main+0x165) [0x405295] -> /lib64/libc.so.6(__libc_start_main+0xfd) [0x303be1ed5d] -> dovecot-mailbox/dict() [0x403da9] Oct 19 12:34:51 server dovecot: dict(7540): Fatal: master: service(dict): child 7540 killed with signal 6 (core dumps disabled) am I missing something obvious or this is a dovecot bug? # 2.2.19: /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.9 (357ac0a0e68b+) # OS: Linux 2.6.32-573.1.1.el6.x86_64 x86_64 Red Hat Enterprise Linux Server release 6.7 (Santiago) auth_master_user_separator = * auth_username_format = %Ln dict { acl = mysql:/etc/dovecot/dovecot-dict-acl.conf.ext } disable_plaintext_auth = no instance_name = dovecot-mailbox lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes listen = * lmtp_rcpt_check_quota = yes lmtp_save_to_detail_mailbox = yes mail_fsync = always mail_gid = vmail mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = " mail_log notify acl mailbox_alias quota listescape" mail_uid = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex im ap4flags copy include variables body enotify environment mailbox date index ihave duplicate imapflags notify mbox_write_locks = fcntl mmap_disable = yes namespace { list = children location = maildir:%%h/Mail:INDEX=~/shared/%%u:INDEXPVT=~/shared-pvt/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } 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 } mailbox sent_mail_folder { special_use = \Sent } mailbox trash_folder { special_use = \Trash } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-pass_db-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = proxy::acl mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename flag_change append mail_log_fields = uid box msgid from subject size flags sieve = file:~/sieve;active=~/.dovecot.sieve sieve_extensions = +notify +imapflags sieve_max_actions = 32 sieve_max_redirects = 25 sieve_max_script_size = 1M sieve_quota_max_storage = 10M } protocols = imap pop3 lmtp sieve service auth { unix_listener auth-userdb { group = vmail } } service dict { unix_listener dict { group = dovecot mode = 0660 user = vmail } } service lmtp { inet_listener lmtp { port = 24 } } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } service_count = 1 } service managesieve { process_limit = 1024 } ssl = no userdb { args = /etc/dovecot/dovecot-user_db-sql.conf.ext driver = sql } verbose_proctitle = yes protocol lmtp { mail_plugins = " mail_log notify acl mailbox_alias quota listescape sieve" } protocol lda { mail_plugins = " mail_log notify acl mailbox_alias quota listescape sieve" } protocol imap { mail_plugins = " mail_log notify acl mailbox_alias quota listescape imap_acl imap_quota" } protocol sieve { managesieve_implementation_string = Dovecot Pigeonhole managesieve_logout_format = bytes=%i/%o managesieve_max_compile_errors = 1 managesieve_max_line_length = 65536 } protocol pop3 { mail_plugins = " mail_log notify acl mailbox_alias quota listescape" }

TLS communication director -> backend with X.509 cert checks?
by Heiko Schlittermann 19 Oct '15

19 Oct '15

Hello, using Dovecot 2.2.9 and a setup with directors and backends. The communication between directors and backends needs to be TLS secured. The director config contains a list of hostnames for the backends. (implicit list because of multiple A/AAAA records for a single hostname or explicit list of several host names) On connection setup from a client the director connects to the selected backend. But it seems (not checked in the source yet), that for SSL certificate verification the director doesn't know the original host name anymore. The certificate's CN gets compared to the IP address the director connects to. Oct 12 23:56:51 director2 dovecot: director: Error: director(2001:683:921:f33::5:1:9090/out): connect() failed: Connection reset by peer Oct 12 23:57:53 director2 dovecot: imap-login: Error: proxy: hostname doesn't match SSL certificate at 2001:683:921:f33::5:fe:993: user=<foo>, method=PLAIN, rip=2001:638:912:f33::1:1, lip=2001:638:912:f33::5:2, TLS, session=<fLrUa+8hggAgAQY4CRIPMwAAAAAAAQAB> In 10-directors.conf I've: director_mail_servers = backend1.<domain> backend2.<domain> Should I create certificates with IP address in SAN? (Any hint about the correct syntax for the openssl.conf is welcome). Or is there any chance that this is fixed already or will be fixed in the near future or even better, that it's my fault?
