[Dovecot] German Umlauts in folder name and sieve
by Christian Rößner 27 Dec '13

27 Dec '13

Hi, I had created an imap folder that has German Umlauts in it: „RA Rößner - Merle“ When finished, the result looks like this on filesystem: drwx------ 3 vmail vmail 4096 Dec 27 11:02 RA Ro&AwgA3w-ner - Merle/ I wrote this sieve script (with SOGo): if anyof (address :regex "from" "@.*\\.ra-roessner-merle\\.de") { fileinto "RA Ro&AwgA3w-ner - Merle"; stop; } That creates a new IMAP folder with exactly this strange name. Can I change this somehow? # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 3.11.2-hardened x86_64 Gentoo Base System release 2.2 auth_master_user_separator = * auth_mechanisms = plain login cram-md5 digest-md5 ntlm auth_verbose = yes default_vsz_limit = 512 M hostname = mail.roessner-net.de imap_client_workarounds = tb-extra-mailbox-sep tb-lsub-flags lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c %k mail_access_groups = vmail mail_attachment_dir = /var/mail/virtual/copymail/attachments mail_gid = vmail mail_location = mdbox:~/mdbox mail_plugins = quota acl fts fts_lucene zlib mail_log notify mail_privileged_group = mail 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 mdbox_rotate_size = 128 M namespace { list = children location = mdbox:%%h/mdbox prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = mailbox Archive { auto = subscribe special_use = \Archive } mailbox "Deleted Messages" { special_use = \Trash } mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk-E-Mail { auto = subscribe special_use = \Junk } mailbox Junk { special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } mailbox junkmail { special_use = \Junk } prefix = separator = / type = private } passdb { args = /etc/dovecot/master-users driver = passwd-file master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = file:/var/mail/virtual/shared-mailboxes.db fts = lucene fts_autoindex = yes fts_lucene = whitespace_chars=@. quota = dict:User quota::file:%h/mdbox/dovecot-quota quota_grace = 10%% quota_rule = *:storage=300M:messages=20000 quota_status_nouser = DUNNO quota_status_overquota = 552 5.2.2 Mailbox is full quota_status_success = DUNNO quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u quota_warning3 = -storage=100%% quota-warning below %u sieve = ~/.dovecot.sieve sieve_dir = ~/sieve zlib_save = gz zlib_save_level = 6 } protocols = imap pop3 lmtp sieve service auth-worker { extra_groups = ssl-cert unix_listener auth-worker { mode = 0600 user = vmail } user = vmail } service auth { extra_groups = ssl-cert unix_listener auth-userdb { mode = 0600 user = vmail } user = vmail } service config { unix_listener config { mode = 0600 user = vmail } } service dict { unix_listener dict { mode = 0600 user = vmail } } service lmtp { unix_listener /var/spool/postfix/private/lmtp-dovecot { group = postfix mode = 0666 user = postfix } } service quota-status { client_limit = 1 executable = quota-status -p postfix inet_listener { port = 12340 } } service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = vmail } ssl_cert = </etc/ssl/certs/mail.roessner-net.de.pem ssl_key = </etc/ssl/private/mail.roessner-net.de.key.pem userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } verbose_proctitle = yes protocol lmtp { mail_plugins = quota acl fts fts_lucene zlib mail_log notify sieve } protocol lda { mail_plugins = quota acl fts fts_lucene zlib mail_log notify sieve } protocol imap { mail_max_userip_connections = 50 mail_plugins = quota acl fts fts_lucene zlib mail_log notify imap_quota imap_acl imap_zlib } Thanks in advance -Christian Rößner -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Axel von der Ohe, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

[Dovecot] Question re: indexes
by Charles Marcus 26 Dec '13

26 Dec '13

Hi all, On the old/current dovecot server, I have disabled on disk indexes: mail_location = maildir:~/:INDEX=MEMORY On the new server, I removed the 'INDEX=MEMORY' part, and I now see some new index related files, but what I don't see is the main dovecot.index file... I only have: dovecot.index.cache and dovecot.index.log So... where is the main dovecot.index file? -- Best regards, */Charles/*

[Dovecot] SHA512-CRYPT scheme fails password verification

Hello, If I try to use the crypt schemes provided by libc.

I have dovecot version 2.2.9 on Linux 3.11.0-14-generic x86_64 Ubuntu 13.10 and I get the same results on 32-bit Debian as well. Does anyone have idea what's wrong? Thanks in advance, Jouko Nikula

[Dovecot] Patch for Dovecot's quota policy daemon
by Peer Heinlein 24 Dec '13

24 Dec '13

Hi Timo, we wrote a simple Patch for the Dovecot quota policy daemon. If a user is over quota, I prefer blocking the user sending e-mails, so I need a policy daemon, that's able to use the envelope or sasl sender as lookup key. I'd be happy if that patch can become part of the normale Dovecot releases.

[Dovecot] Eliminate legacy INBOX namespace - how?
by Charles Marcus 24 Dec '13

24 Dec '13

Hi all, Our mailstore was converted from a Courier-IMAP system last year, but I am planning a migration to a shiny new VM, and would really like to clean things up and do away with the legacy INBOX namespace. My goal is to simplify IMAP client setup - no special 'INBOX' namespace needed, they just enter the server info and credentials. Also important because I will be rolling out SOGo, which has a nice web interface, and I want the mailstore to be as close to default dovecot settings as possible - although I do plan on converting from maildir to mdbox when I do the conversion I also don't want other folders to show up as subfolders of the Inbox in IMAP clients, they should all show up on the same level as the Inbox. I've read http://wiki2.dovecot.org/Migration/Courier, but I don't see anything about how to eliminate this stupid legacy INBOX. namespace, so that new IMAP clients won't show all folders as subfolders of the INBOX unless/until they add the INBOX namespace prefix in the advanced settings. I've also been reading http://wiki2.dovecot.org/Namespaces, but I'm still confused as to how to go about this. Currently I have: 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 = . } The wiki recommends avoiding the 'alternative' of having two different namespaces, so I don't want to do that. Also - it would be ok if existing clients had temporary issues displaying folders properly until the INBOX prefix was removed (I would give everyone plenty of advance warning). Anyone ever done this before? Any suggestions Timo? Note: I am planning a migration to a new mail server (VM), so could make any filesystem layout changes when I do this if necessary. Thanks, -- Best regards, */Charles/*

[Dovecot] Is the users password available from a mail_filter?
by martijn.list 23 Dec '13

23 Dec '13

Hi, I'm working on a Dovecot encryption module which uses the mail filter plugin to encrypt/decrypt the message "on the fly". I was wondering whether it is possible to access the password (or a hashed password) of the user. It seems that only the user (using the %u parameter) is available to the mail_filter plugin. Any idea how to get hold of the (possibly hashed) password? Kind regards, Martijn Brinkers

[Dovecot] [dovecot-2.2.5] Duplicates in mdbox
by radek 23 Dec '13

23 Dec '13

Hi I have strange situation with one of mailboxes in mdbox format. Some messages are duplicated, not all. I am sure that is not sieve or another mail client issue, because access is via roundcube without sieve plugin. In maillog I have not found any suspicious information about this problem and i can see that from postfix do dovecot-lda was piped only one copy of message. Radek
