[Dovecot] doveadm altmove to gzipped-mdbox
by Claus 20 May '13

20 May '13

Hi, im wondering if it's possible to store old messages in a compressed mdbox on alternate storage. The main storage is uncompressed mdbox. I tried something like: doveadm -Dv -o "plugin/zlib_save=gz" altmove -u testuser sentbefore 8d Could someone tell me if it's possible and give me a hint how this can be done? I tried this with dovecot-2.2 Claus

[Dovecot] Empty file in maildirs
by Roel Wagenaar 20 May '13

20 May '13

I am cleaning up some old users, and found that in every maildir folder there is an empty file called maildirfolder, created at the time the original dovecot was installed. Is this empty file necessary for dovecot, or is it left there in an upgrade proces and can it be removed?

[Dovecot] v2.2.2 released
by Timo Sirainen 20 May '13

20 May '13

http://dovecot.org/releases/2.2/dovecot-2.2.2.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.2.tar.gz.sig It's been a while since v2.2.1. I think all of the bad bugs in v2.2 series should be fixed by now, so here's a new release. I think there are still some small URLAUTH bugs left though, so you might want to wait before enabling it in production (imap_urlauth_host is empty by default, which disables it). + zlib: Keep the last mail cached uncompressed in a temp file. This fixes performance when doing small partial fetches from a large mail. + acl: If plugin { acl_defaults_from_inbox = yes } is set, get the default ACLs for private and shared namespaces from the user's INBOX. (This probably will become default in v2.3.) + pop3: Added pop3_deleted_flag setting to switch POP3 deletions to only hide the messages from POP3, but still be visible via IMAP. - ACL plugin: Mailbox creation wasn't actually checking any ACLs and always succeeded (due to some v2.2 API changes). The created mailbox couldn't have been accessed though, so this couldn't have caused any data leak. - IMAP: Various URLAUTH fixes. - IMAP: Fixed a hang with invalid APPEND parameters. - IMAP LIST-EXTENDED: INBOX was never listed with \Subscribed flag. - mailbox_list_index=yes still caused crashes. - maildir: Fixed a crash after dovecot-keywords file was re-read. - maildir: If files had reappeared unexpectedly to a Maildir, they were ignored until index files were deleted. - Maildir: Fixed handling over 26 keywords in a mailbox. - Maildir++: Fixed mail_shared_explicit_inbox=no - namespace { prefix="" list=no } was listing mailboxes. - imap/pop3-login proxying: Fixed a crash if TCP connection succeeded, but the remote login timed out. - Case-insensitive search/sort didn't work correctly for all unicode characters, as specified by i;unicode-casemap comparator. If full text search indexes were used, they need to be rebuilt for old mails to be handled correctly. (This bug has existed always in Dovecot.)

Hello everyone. I have dovecot version 1.2.8 installed from source. This morning I installed the sieve plugin to sort emails, and though the install reported no errors, the plugin doesn't seem to function, and no mention of it is made in the logs when I turn on verbose logging. dovecot --version 1.2.8 dovecot -n # 1.2.8: /usr/local/etc/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.0 base_dir: /usr/local/var/run/dovecot/ log_path: /dev/stderr info_log_path: /dev/stderr log_timestamp: protocols: imap imaps pop3s listen(default): 127.0.0.1:143 listen(imap): 127.0.0.1:143 listen(pop3): * ssl_listen(default): 192.168.1.1:993 ssl_listen(imap): 192.168.1.1:993 ssl_listen(pop3): 192.168.1.1:995 ssl_cert_file: /var/qmail/control/servercert.pem ssl_key_file: /var/qmail/control/servercert.pem ssl_cipher_list: ALL:!LOW verbose_ssl: yes login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login verbose_proctitle: yes first_valid_uid: 89 last_valid_uid: 89 mail_location: maildir:~/Maildir mail_debug: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %v-%u namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)mail.domain.com hostname: mail.domain.com mail_plugins: sieve mail_plugin_dir: /usr/local/lib/dovecot/lda deliver_log_format: msgid=%m: %$ sieve: /home/vpopmail/domains/%d/%n/sieve sieve_global_path: /usr/local/etc/default.sieve log_path: /var/log/qmail/sieve/dovecot.log info_log_path: /var/log/qmail/sieve/dovecot.log auth default: user: vpopmail passdb: driver: vpopmail userdb: driver: vpopmail plugin: quota: maildir Here is the config.log from sieve root@myplace:/usr/local# head dovecot-1.2-sieve-0.1.19/config.log This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake.

You lost me. How did you "set up maildir to somewhere else"? You ought to supply configurations (output of dovecot -n), and log entries of the problem. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Quota not working with dict proxy
by Chris Richards 16 May '13

16 May '13

Hello all, I'm sure this has been covered somewhere before, but my googlefu is not up to the challenge. Basically, I'm trying to configure quota plugin to use a dictionary service (specifically proxy with mysql) so that I can store the quota usage in a database and use that information in a lookup for postfix to reject mail if over quota. I'm doing this because postfix+avamis+dovecot setup with amavis re-injecting into postfix results in mail being effectively accepted before dovecot lmtp knows if mailbox is full. I'm currently using quota maildir: quota = maildir:User quota and this works; doveadm -Df tab quota get -u 'user@domain' Quota name Type Value Limit % User quota STORAGE 55388 204800 27 User quota MESSAGE 4883 - 0 When I use quota dict: quota = dict:User quota:%u:proxy::quota I get this: "doveadm -f tab quota get -u user@domain" Quota name Type Value Limit % User quota STORAGE 0 204800 0 User quota MESSAGE 0 - 0 So far so good. But manually setting database entry to values retrieved above with maildir quota results in this: Quota name Type Value Limit % User quota STORAGE 54 204800 0 User quota MESSAGE 4883 - 0 I'm guessing this is returning values in KB, so that makes sense, I guess. Attempting to recalc quota on one account using command: "doveadm -f tab quota recalc -u user@domain" returns with nothing, and when I repeat 'quota get' command, it says: doveadm(user@domain): Fatal: User doesn't exist Err............what?! Indeed, looking in the database shows the account in question was actually DELETED! Obviously, I've got something messed here, but I don't know what. I need some guidance here. Dovecot version is 2.1.12 Here is my config: # 2.1.12: /etc/dovecot/dovecot.conf # OS: Linux 3.7.5-hardened-r1 x86_64 Gentoo Base System release 2.1 ext4 auth_master_user_separator = * auth_mechanisms = plain login auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@& auth_verbose_passwords = plain default_process_limit = 200 dict { quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no login_greeting = Awaiting command... mail_location = maildir:/home/vmail/%d/%n/Maildir mail_plugins = " quota" mail_privileged_group = 100 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 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 = INBOX. separator = . type = private } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { expire = Trash 7 expire2 = Trash/* 7 expire3 = Spam 7 quota = dict:User quota:%u:proxy::quota quota_rule = *:storage=200M quota_warning = storage=99%% quota-warning 99 %n %d quota_warning2 = storage=95%% quota-warning 95 %n %d quota_warning3 = storage=80%% quota-warning 80 %n %d quota_warning4 = -storage=95%% quota-warning 'less than 95' %n %d sieve = ~/.dovecot.sieve sieve_default = /home/vmail/dovecot/sieve/default.sieve sieve_dir = ~/sieve sieve_global_dir = /home/vmail/dovecot/sieve } protocols = imap pop3 sieve lmtp service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = dovecot mode = 0666 user = dovecot } user = $default_internal_user } service dict { unix_listener dict { mode = 0600 user = vmail } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service quota-warning { executable = script /etc/dovecot/quota-warning.sh unix_listener quota-warning { user = vmail } user = dovecot } ssl_cert = </etc/ssl/dovecot/server.pem ssl_key = </etc/ssl/dovecot/server.key userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lmtp { mail_plugins = sieve quota postmaster_address = postmaster@domain } protocol lda { mail_plugins = " quota sieve quota" } protocol imap { mail_max_userip_connections = 20 mail_plugins = " quota quota imap_quota" } protocol pop3 { mail_plugins = " quota quota" } >From dovecot-dict-sql.conf.ext: connect = host=localhost dbname=maildb user=dbuser password=dbpass # CREATE TABLE quota ( # username varchar(100) not null, # bytes bigint not null default 0, # messages integer not null default 0, # primary key (username) # ); map { pattern = priv/quota/storage table = email username_field = address value_field = quota_bytes } map { pattern = priv/quota/messages table = email username_field = address value_field = quota_messages } # CREATE TABLE expires ( # username varchar(100) not null, # mailbox varchar(255) not null, # expire_stamp integer not null, # primary key (username, mailbox) # ); map { pattern = shared/expire/$user/$mailbox table = email value_field = expire_stamp fields { address = $user maildir = $mailbox } } Other than some guesswork, I've not got the FOGGIEST idea what the settings in the file actually mean; it doesn't seem to be documented anywhere. Also, the quota plugin settings, at least with respect to using a proxy service, don't seem to be real explanatory either, e.g. the reason I'm using %u for the user is because I stumbled across a post suggesting that leaving it blank would result in just getting the username instead of the username@domain. This is not at all obvious from the documentation, IMO. The docs would benefit greatly from some example use cases (no, I'm not volunteering; I'm TERRIBLE with documentation ;) ). Anyway, if someone could proffer some help or at least guidance here, I'd be very grateful.

[Dovecot] dovecot 2.2.0 corrupts mailboxes?
by manu＠netbsd.org 16 May '13

16 May '13

Hi On april 17th, I upgraded from dovecot 2.1.13 to 2.2.0. Since that time, I had two different users that reported received three incident of messages that disapeared from their mailboxes. The mailbox format is mbox on local FFS filesystem (no NFS), and I use filesystem quotas (but both users are far from filling their quotas). When the message disapeared, it was always a whole rand of dates. On the last incident reported, the user also saw some message being duplicated many times. There is something interesting in the logs: May 4 20:16:30 volanges dovecot: imap(jdoe): Error: Cached message size smaller than expected (2000 < 8063) May 4 20:16:30 volanges dovecot: imap(jdoe): Error: Corrupted index cache file /mail/indexes/jdoe/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 141869 May 4 20:19:48 volanges dovecot: imap(jdoe): Error: Cached message size smaller than expected (9711 < 16248) May 4 20:19:48 volanges dovecot: imap(jdoe): Error: Corrupted index cache file /mail/indexes/jdoe/mail/.imap/Arxiv/dovecot.index.cache: Broken physical size for mail UID 4383 May 4 21:14:35 volanges dovecot: imap(jdoe): Error: Cached message size smaller than expected (1878 < 8066) May 4 21:14:35 volanges dovecot: imap(jdoe): Error: Corrupted index cache file /mail/indexes/jdoe/mail/.imap/CNRS/dovecot.index.cache: Broken physical size for mail UID 290 May 4 21:15:17 volanges dovecot: imap(jdoe): Error: Cached message size smaller than expected (17285 < 24440) May 4 21:15:17 volanges dovecot: imap(jdoe): Error: Corrupted index cache file /mail/indexes/jdoe/mail/.imap/Commandes/dovecot.index.cache: Broken physical size for mail UID 680 Does that ring a bell?

[Dovecot] [PATCH] example-config: fix to also distribute auth-dict.conf.ext in

Hi, When trying to patch the dovecot 2.2.1 release with latest upstream patches I generated out of the repository, the patch fails to apply, because 'doc/example-config/conf.d/auth-dict.conf.ext' is not distributed within the release tarball. Attached patch should fix the issue. Cheers, Chris
