mailbox_list_index and maildir_very_dirty_syncs are in conflicts?
by Alessio Cecchi 06 Dec '15

06 Dec '15

Hi, I’m running Dovecot 2.2.19 with Maildir as storage and LDA for delivery. I noticed that if I set mailbox_list_index=yes and maildir_very_dirty_syncs=yes when I login via IMAP the STATUS command don’t “see” new messages in sub-folders (like Spam). Example, a new message as arrived in Spam folder (I can see in Maildir/new/) but IMAP STATUS don’t see it: . STATUS Spam (MESSAGES UNSEEN) * STATUS Spam (MESSAGES 139 UNSEEN 0) (in this case the date of “dovecot.list.index” files is not updated) If I comment out mailbox_list_index=yes or maildir_very_dirty_syncs=yes I can see the new message: . STATUS Spam (MESSAGES UNSEEN) * STATUS Spam (MESSAGES 140 UNSEEN 1) (in this case the date of “dovecot.list.index” files is updated after the STATUS command) Instead the SELECT command works fine always. An importante note, my dovecot LDA configuration (on MX servers) don’t update index files: protocol lda { mail_location = maildir:~/Maildir:INDEX=MEMORY mail_plugins = quota acl expire fts fts_solr zlib sieve } These because I need to filter incoming email via Sieve but since I cannot use LMTP (and Director) on MX (but I have Director for POP/IMAP access) the only way for not corrupting dovecot.index files is not update their on delivery emails. But reading http://wiki2.dovecot.org/MailLocation/Maildir this shouldn’t be a problem (Optimizations “maildir_very_dirty_syncs=yes” … It's still safe to deliver new mails to new/ …) since MX deliver new emails in new/. Is a Dovecot limit or is a problem of my configuration? Thanks my configuration: # 2.2.19 # Pigeonhole version 0.4.9 auth_cache_negative_ttl = 5 mins auth_cache_size = 10 M auth_cache_ttl = 20 mins auth_master_user_separator = * auth_worker_max_count = 50 deliver_log_format = msgid=%m, from=%f, subject="%s": %$ dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext expire = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no first_valid_gid = 89 first_valid_uid = 89 imap_client_workarounds = delay-newmail tb-extra-mailbox-sep tb-lsub-flags imap_idle_notify_interval = 29 mins imap_logout_format = in=%i out=%o session=<%{session}> last_valid_gid = 89 last_valid_uid = 89 lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes listen = 10.96.3.156 login_trusted_networks = 10.0.0.0/24 mail_fsync = always mail_location = maildir:~/Maildir mail_plugins = quota acl expire fts fts_solr zlib mailbox_list_index = yes maildir_very_dirty_syncs = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate vnd.dovecot.duplicate mmap_disable = yes namespace { list = children location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = shared/%%n/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Spam { auto = subscribe special_use = \Junk } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / } passdb { args = /etc/dovecot/dovecot-deny-sql.conf.ext deny = yes driver = sql } passdb { args = /etc/dovecot/extra/master-users driver = passwd-file master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile acl_shared_dict = proxy::acl antispam_backend = mailtrain antispam_mail_notspam = --ham antispam_mail_sendmail = /usr/bin/sa-learn antispam_mail_spam = --spam antispam_spam = Spam antispam_trash = Trash expire = Trash expire2 = Spam expire_dict = proxy::expire fts = solr fts_solr = url=http://10.0.0.1:8983/solr/ quota = maildir:UserQuota quota2 = dict:Quota Usage::noenforcing:proxy::sqlquota quota_grace = 10M quota_rule2 = Trash:storage=+100M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u sieve = ~/.dovecot.sieve sieve_before = /etc/dovecot/sieve/before.sieve sieve_dir = ~/sieve sieve_extensions = +vnd.dovecot.duplicate -vacation zlib_save = gz zlib_save_level = 6 } pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_fast_size_lookups = yes pop3_logout_format = top=%t/%p, retr=%r/%b, del=%d/%m, size=%s, bytes=%i/%o, session=<%{session}> protocols = imap pop3 sieve sendmail_path = /var/qmail/bin/sendmail service auth { client_limit = 6524 unix_listener auth-userdb { group = vchkpw mode = 0660 user = vpopmail } } service dict { process_limit = 500 unix_listener dict { group = vchkpw mode = 0660 user = vpopmail } } service imap-login { process_min_avail = 4 service_count = 0 } service imap-postlogin { executable = script-login /etc/dovecot/scripts/imap-postlogin.sh unix_listener imap-postlogin { group = vchkpw mode = 0660 user = vpopmail } user = vpopmail } service imap { executable = imap imap-postlogin process_limit = 5000 service_count = 100 vsz_limit = 384 M } service managesieve-login { inet_listener sieve { port = 4190 } } service pop3-login { process_min_avail = 4 service_count = 0 } service pop3-postlogin { executable = script-login /etc/dovecot/scripts/pop3-postlogin.sh unix_listener pop3-postlogin { group = vchkpw mode = 0660 user = vpopmail } user = vpopmail } service pop3 { executable = pop3 pop3-postlogin process_limit = 1024 service_count = 100 } service quota-warning { executable = script /etc/dovecot/scripts/quota-warning.sh unix_listener quota-warning { user = vpopmail } user = vpopmail } ssl_cert = </etc/dovecot/ssl/wildcard.pem ssl_key = </etc/dovecot/ssl/wildcard.key ssl_protocols = !SSLv2 !SSLv3 submission_host = 127.0.0.1 userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } verbose_proctitle = yes protocol lda { mail_location = maildir:~/Maildir:INDEX=MEMORY mail_plugins = quota acl expire fts fts_solr zlib sieve } protocol imap { mail_max_userip_connections = 25 mail_plugins = quota acl expire fts fts_solr zlib imap_quota imap_acl imap_zlib } protocol sieve { mail_max_userip_connections = 2 } protocol pop3 { mail_max_userip_connections = 5 } -- Alessio Cecchi Postmaster AT http://www.qboxmail.it http://www.linkedin.com/in/alessice

Released Pigeonhole v0.4.10.rc1 for Dovecot v2.2.20.rc1
by Stephan Bosch 05 Dec '15

05 Dec '15

Hello Dovecot users, Here's the Pigeonhole RC that goes with the Dovecot RC. There is a conflict with the t_str_trim() function. To be able to quickly release Dovecot, Timo has reverted the involved change so that 0.4.9 will still compile with the final Dovecot v2.2.20 release. This Pigeonhole RC will therefore not compile against the final Dovecot release (only against v2.2.20.rc1), which I will mend quickly once Dovecot v2.2.20 is released. Changelog v0.4.10.rc1: + Implemented the Sieve mime and foreverypart extensions (RFC 5703). These are fully implemented. The interaction with the editheader extension needs some work, but this should not influence most uses; i.e., changes by the editheader extension are not always visible using foreverypart/mime. + Sieve body extension: Properly implemented the `:text' body transform. It now extracts text for HTML message parts. + Sieve enotify extension: mailto method: Implemented the sieve_notify_mailto_envelope_from setting. This allows configuring the source of the notification sender address for e-mail notifications. This is similar to what already can be configured for redirect. + Added a sieve_enabled (defaults to 'yes') setting that allows explicitly disabling Sieve processing for particular users. This used to be possible by setting `sieve=', but ever since the sieve_before, sieve_after and sieve_default settings were added, this method was not reliable anymore. - variables extension: Fixed handling of empty string by the `:length' set modifier. An empty string yielded an empty string rather than "0". - Fixed memory leak in the Sieve script byte code dumping facility. Extension contexts were never actually freed. - Fixed handling of implicit keep when the last Sieve script is a global one. In that case the implicit keep action was executed in global context, which could mean that trivial (quota) errors ended up in the system log file, rather than the user log file. - doveadm sieve plugin: Fixed crashes caused by incorrect context allocation in the sieve command implementations. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.10… http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.10… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release candidate and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

Content-Enconding

Hi, With Apache one may use "mod_deflate" in order to reduce bandwidth by using e.g. gzip to compress the http traffic. I would like to use something similar for email traffic between mail clients to dovecote and postfix. My questions are: a) Is this established well enough in most mail clients? b) Can you recomment a good tutorial for this? Thank you very much

Interpreting keywords
by Mark Foley 04 Dec '15

04 Dec '15

I've marked several messages in Thunderbird using tags. Tags used are: 0 Important 1 Work 2 To Do 3 Personal 4 Later The messages so tagged appear to have the flag fields set in the IMAP Maildir: cur/1449002162.8993_0.mail:2,Sb cur/1449001929.28087_0.mail:2,Sad I've looked in dovecot-keywords and find: $ more dovecot-keywords 0 $label1 1 $label2 2 $label3 3 $label4 I assume these "$label" values are macros that possibly refer to "Important", "Work", etc., but where are these $label's defined? Are they defined in the dovecot configs somewhere or does the mail client just "know" what these correspond to? --Mark
