[Dovecot] Links on MainConfig wiki page not working
by Matthijs Kooijman 29 Apr '09

29 Apr '09

Hi all, while looking through the wiki page MainConfig, I noticed a lot of wannabe-links, for example: <doc/wiki/SSL> This looks like it should have been converted to a wiki link automatically, but apparently isn't. Would be good to have this fixed? Gr. Matthijs

[Dovecot] Quota/Dict Postgres Trigger
by Warren Volz 29 Apr '09

29 Apr '09

I posted the trigger for v1.1 versions of Dovecot on the Wiki (http://wiki.dovecot.org/Quota/Dict ) and while I understand the comment posted about two process inserting at the same time, I'm not sure I understand how this is fixed in v1.2 other than via the revised trigger in the Wiki. Does someone have a known working trigger that will handle a double insert correctly? Also, out of curiosity why wasn't the code for dict written to do an update first and then an insert if this failed? That would eliminate the need for this trigger. Thanks. -Warren

[Dovecot] Mail statistics
by Timo Sirainen 29 Apr '09

29 Apr '09

I just committed a mail statistics gathering patch to v1.2: http://hg.dovecot.org/dovecot-1.2/rev/fdaf0bda70d5 It keeps track of: struct mail_private { .. /* open(), stat(), .. */ unsigned long stats_dentry_lookup_count; /* fstat() mostly */ unsigned long stats_attr_lookup_count; /* number of files we've opened and read */ unsigned long stats_files_read_count; /* number of bytes we've had to read from files */ unsigned long long stats_files_read_bytes; /* number of cache lookup hits */ unsigned long stats_cache_hit_count; So it's possible to write a plugin that does whatever with those values. You can get them per-command or even per-single-mail-access. Any thoughts on if those are good variables? Like would it be useful to split dentry lookups to opens and stats?

[Dovecot] Virtual mailbox plugin, 4 days of struggling
by Brandon Lamb 28 Apr '09

28 Apr '09

Hello, I finally got an INBOX to work, but is virtual mailbox plugin only meant to create a virtual inbox, or should I be able to have an Allmails virtual folder that is viewable in my imap client? if ~/virtual/ is my location, would I create an Allmails directory in the virtual/ or virtual/INBOX/Allmails. Im fairly confused on how this is suppose to work. I was trying to duplicate the gmail-like setup on the wiki but I cant get it work. Per the wiki, i put in the userdb inbox select, but made swapped pop3 for imap zeus:/etc/dovecot# dovecot -n # 1.2.rc3: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-1-amd64 x86_64 Debian squeeze/sid base_dir: /var/run/dovecot/ log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/info.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap pop3 lda listen: 208.200.251.181 ssl: no disable_plaintext_auth: no login_dir: /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 login_greeting: Hello there. login_log_format_elements: <%u> <%r> login_log_format: %s login_process_per_connection: no login_process_size: 128 login_processes_count: 4 login_max_processes_count: 20 login_max_connections: 128 mail_max_userip_connections(default): 15 mail_max_userip_connections(imap): 15 mail_max_userip_connections(pop3): 1 verbose_proctitle: yes first_valid_uid: 8 last_valid_uid: 8 first_valid_gid: 8 last_valid_gid: 8 mail_access_groups: mail mail_privileged_group: mail mail_uid: 8 mail_gid: 8 mail_location: maildir:~/:INDEX=dovecot-index mailbox_idle_check_interval: 60 mail_debug: yes fsync_disable: yes mailbox_list_index_disable: no 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 virtual autocreate mail_plugins(imap): quota imap_quota virtual autocreate 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 mail_log_prefix: %Ls <%u>: imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): pop3_no_flag_updates(default): no pop3_no_flag_updates(imap): no pop3_no_flag_updates(pop3): yes pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_logout_format(default): top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_logout_format(imap): top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_logout_format(pop3): retr=%r/%b, del=%d/%m, size=%s namespace: type: private separator: / hidden: yes list: yes subscriptions: yes namespace: type: private separator: / prefix: virtual/ location: virtual:~/virtual:INDEX=~/dovecot-index list: yes subscriptions: yes namespace: type: private separator: / prefix: RealMails/ hidden: yes list: no subscriptions: yes auth default: mechanisms: plain login default_realm: pacwebdev.com cache_ttl: 60 debug: yes worker_max_count: 60 passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/run/dovecot/auth-client mode: 438 user: mail group: mail master: path: /var/run/dovecot/auth-master mode: 438 user: mail group: mail plugin: quota: maildir quota_rule: Trash:ignore quota_rule2: Sent:ignore quota_rule3: Spam:ignore quota_rule4: Archive:ignore quota_rule5: Sent Items:ignore quota_rule6: Deleted Items:ignore quota_warning: storage=95%% /etc/dovecot/quota-warning.sh 95 quota_warning2: storage=80%% /etc/dovecot/quota-warning.sh 80 autocreate: Trash autocreate2: Spam autosubscribe: Trash autosubscribe2: Spam auth_socket_path: /var/run/dovecot/auth-master

[Dovecot] Dovecot auth user lookup patch for maildrop
by mr.maX 26 Apr '09

26 Apr '09

Hi, recently I started using maildrop as a MDA doing lightweight filtering in a Postfix/Dovecot mail server combo. Only thing missing was the fact that maildrop couldn't perform user lookups against a user database that was already being served by Dovecot (for smtp auth in Postfix and for imap access obviously) in order to easily determinate proper mailbox location and home directory of my "virtual" users when delivering e-mails. I wanted to avoid having another authentication daemon running (Courier Authlib) that would be serving this data to maildrop, so I've spent some time to write an extension for maildrop that would allow it to do user lookups directly against Dovecot in a similar way how they are done by Dovecot's LDA deliver. For everyone that are using maildrop in a similar setup that may be interested in this extension, a patch against maildrop version 2.0.4 can be downloaded from the following location: http://www.max.rs/ozone/maildrop-2.0.4-dovecotauth.patch.txt When this patch is applied, maildrop will be extended with another command line option "-t", which can be used to specify the location of Dovecot's master auth socket that will be used when performing user lookups. There's a readme file (README.dovecotauth) together with patch with a little bit more information regarding the use of this extension. I hope that some of you may find my modification to maildrop useful. -- Best Regards, Marko Njezic - mr.maX @ MAX Interactive corp.

[Dovecot] Virtual mailboxes, howto, examples, help? =)
by Brandon Lamb 24 Apr '09

24 Apr '09

Using 1.2rc3 maildir format maildir /mail/example.com/j/johndoe/{cur,new,tmp} Is there more documentation and examples on how to configure virtual mailboxes, or maybe more info on what it is suppose to do? From what I could understand on the wiki, i could create a fake/virtual folder under /mail/example.com/j/johndoe/virtual/allmail/ and inside that dir create dovecot-virtual with INBOX all And then in my mail client i would see virtual/allmail and when i click that folder it shows me mail from all my normal maildir folders? Is my thinking of how to use virtual mailboxes totally off, or am I trying to use it for what it is suppose to be used for? So far i have been messing with various values = yes/no using the following namespace private { prefix = virtual/ separator = / # location = virtual:~/virtual location = virtual:~/virtual:LAYOUT=maildir++ list = yes inbox = no subscriptions = yes hidden = no } # The default namespace that is visible to IMAP clients namespace private { prefix = separator = / location = maildir:~/ list = yes inbox = yes subscriptions = yes hidden = no } I dont know if I am retarded in my lack of ability to figure this out or what

[Dovecot] bad maildir location
by denis 23 Apr '09

23 Apr '09

Hi, I use dovecot 1.0.15 on Debian Lenny. In my /etc/dovecot/dovecot-sql.conf, i use user_query = SELECT path, 33 AS uid, uid AS gid FROM mail_users WHERE alias = '%u' The result is something like this /var/alternc/mail/d/denis_collectifs.net and is the correct location (the Maildir is created by an script) But the problem is that dovecot creates (when you log in for the first time) a directory in the form of the exact address. Here for example, /var/alternc/mail/d/denis(a)collectifs.net And so all connections will be on an empty location. How is it possible to resolve this? As mail_location I have this "maildir:/var/alternc/mail/%1u/%u/Maildir" which is not really correct. Thanks Denis PS: For now, I temporarily symlinks /var/alternc/mail/d/denis(a)collectifs.net /var/alternc/mail/d/denis_collectifs.net

hello, i have a problem with my dovecot installation. sometimes, the thunderbird clients on windows machines complains about: "server is not imap4 compatible". on the server, at the same time, i found this error: Apr 20 16:21:17 harlock dovecot: imap-login: Disconnected: Shutting down: rip=192.168.0.194, lip=10.70.0.1, TLS handshake the imap server is behind a dmz which sometimes drops connections. the server ran without problem until i upgraded from 1.0.rc15 to 1.0.15. after the upgrade i was forced to enhance the proc.sys.fs.inotify.max_user_instances = 1024 because i had error messages about "Inotify instance limit for user exceeded" my question is: does the upgrade triggered a new way of communication between clients and server that exacerbates the problem of dropped connections from the DMZ server? p.s. the dovecot configuration is: $ sudo dovecot -n # 1.0.15: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/certs/harlock_digicert_2009.pem ssl_key_file: /etc/ssl/private/harlock_digicert_2009.key login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_max_processes_count: 256 mail_privileged_group: mail mail_location: maildir:/var/mail/vhosts/turboden.net/%n/ mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds(default): tb-extra-mailbox-sep imap_client_workarounds(imap): tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: mechanisms: plain login default_realm: DOMAIN.LOCAL username_format: %Ln@%Ud passdb: driver: pam userdb: driver: static args: uid=5000 gid=5000 socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix

[Dovecot] Mailbox is locked?
by Kyle Wheeler 23 Apr '09

23 Apr '09

Hello, I recently upgraded from Dovecot 1.1.8 to 1.1.14, and I've started to get errors I never got before. Specifically, I'm getting "Mailbox is locked, will abort in xx seconds" errors. My mail client (mutt) will just sit there in the background (presumably in IDLE) and randomly will show this error (I THINK it has something to do with delivering new messages to the folder; I use the dovecot LDA). Nothing else about my configuration has changed, just the version of dovecot. Does anyone know what could be causing these? I assume it has something to do with the index files, but... Nothing interesting shows up in the log files. How do I get rid of these error messages? Or even begin tracking them down? For what it's worth, mail is stored on the server in Maildirs, and the lock_method is fcntl, the mbox_write_locks is fcntl (I don't set mbox_read_locks). ~Kyle -- For to accuse, requires less eloquence, such is man's nature, than to excuse; and condemnation, than absolution more resembles justice. -- Hobbes, Leviathan

[Dovecot] overnight clients causing lockfiles to be converted to root-owned messages on debian lenny
by Brett Dikeman 23 Apr '09

23 Apr '09

Greetings all, After running for more than a year without issue on debian lenny while it was in the testing- we're now experiencing problems under Lenny/Stable. Dovecot now converts some sort of lockfile into messages, and they're owned by root. The result is a mess; clients can't read their mailboxes with the root-owned files, and when the file is changed to be owned by them, many mail clients don't like the zero-length message (Outlook being one major client with this "problem".) This happens to users who leave their email clients open overnight. I haven't found a cronjob that could be responsible for this. Further details- 64 bit machine, we use maildir, /var/spool/mail is on an xfs volume, and we run postfix, procmail, and spamassassin. Dovecot version is 1.0.15; the machine is fully up-to-date with Debian Stable (Lenny.) Sample log entry of the aftermath; please pardon the sanitizing (host/username): Apr 22 00:08:34 host dovecot: IMAP(user): Fixed a duplicate: 1240289413.9181_0.host:2,S.lock -> 1240373314.P6717Q0M159857.host Apr 22 00:08:34 host dovecot: IMAP(user): Fixed a duplicate: 1240356531.15928_0.host:2,S.lock -> 1240373314.P9995Q3.host Apr 22 00:08:34 host dovecot: IMAP(user): open(/var/spool/mail/user/Maildir/cur/1240373314.P6717Q0M159857.host:2,) failed: Permission denied Brett

[Dovecot] expire-tool
by Jeff Rice 23 Apr '09

23 Apr '09

Hi, I'm having some trouble getting the expire plugin to work, and I'm not sure where to turn for troubleshooting. This is on 1.2rc3. To my dovecot.conf, I've added: mail_plugins = expire under the protocol imap and lda sections. I also added: dict { expire = mysql:/etc/dovecot/dovecot-dict-expire.conf } plugin { expire = Trash 30 Trash/* 30 Spam 30 expire_dict = proxy::expire auth_socket_path = /var/run/dovecot/auth-master } /etc/dovecot/dovecot-dict-expire.conf contains: -- connect = host=/var/run/mysqld/mysqld.sock dbname=email user=XXX password=XXX map { pattern = shared/expire/$user/$mailbox table = expires value_field = expire_stamp fields { username = $user mailbox = $mailbox } } -- I created the table and granted all permissions to the user. The socket is the same one used by the auth_socket process, so that should work. Dovecot restarts fine, but the table is empty. A couple questions: First, the mailboxes to expire are stored as user(a)domain/.INBOX.Trash. How should I list them in the conf file? Also, is there any way to have the system come up to date since older emails already exist in those boxes and should be deleted. Will it detect those, or only start to delete old emails that were delivered after the plugin was enabled? Second, should the table be empty if mail has been delivered & deleted since I enabled the plugin? I assumed it would start to fill. Jeff

[Dovecot] Quota for Shared Folders
by Anton Dollmaier 22 Apr '09

22 Apr '09

Good morning list, first of all: dovecot works really great, the performance is overwhelming (especially compared to courier), the configuration flexible as hell, it is good documented - I love this software. But as things get complicated, I think I need some additional help. I'm using dovecot to replace the currently used courier-mailserver in a shared hosting environment based on the control panel Confixx. Confixx uses per default filesystem-users, giving each mailuser a filesystem-quota, mails are stored in ~/Maildir/. The imap-logins are all in the form of "webxpy", being "webx" the customer (prefix 'web', and a increasing number), and "py" the number of the pop account. Because of the filesystem-quota we moved the indexes to another partition. This basic setup with dovecot works great, with auth directly against the confixx-database etc, imap_quota-plugin, quota-plugin working as expected. We now want to implement shared folders for each customer: all mailaccounts of a customer should be able to subscribe to per-customer shared folders in a specified maildir, thus I re-mapped the usernames with a new user_query (and password_query) to the format of "webxpy@webx" - being "webx" the virtual domain and "webxpy" the mailaccount, but still using "webxpy" as the imap-login (no need for customers to change the login). This also works, we even can control with ACL-vfiles the permissions of specified users, to enable or disable specific folders. The shared folders are specified as a new public namespace and the "domain" is part of the storage-path (see configuration at the end of this mail). To allow easier quota-management (no need to create a new system-user), the quota of the shared folders is maildir-based, with a mysql-quota-dictionary (later, all accounts will be migrated to a virtual-user-mailstorage, with only maildir-quota and no fs-quotas). But when things come to the shared quota, I currently don't know how to solve the wishes of the customer: The current solution for shared folders (at the customer's local site) is based on mdaemon, every shared folder (of a customer, not a single mail-account) has a quota assigned. This quota cannot be exceeded by the users, no more mails can be saved into the shared folders if used space exceeds the hard quota-value. As my tests have shown, dovecot uses a different approach to the quota-issue: users can always move their mails from local folders to the shared namespace, regardless of the shared quota. The quota itself is only checked when receiving new mails, where the combined quota (local + shared) may not be exceeded. If it is, the mail is not delivered to the mailbox. Our quota-config is this: > quota_rule: *:storage=50M:messages=1000 > quota_rule2: Trash:storage=50M:messages=100 > quota_rule3: shared*:storage=100M:messages=1000 (also being altered by user_query, but the scheme is the same) As of dovecot-wiki, this means: Users can save "50M + 50M + 100M" of mails in all specified Folders, so the storage-value for the "shared*"-folders works additionally to the "*"-storage-value. Different from this, we want the following to happen: If the customer exceeds the shared folders-quota, his mail-users may not move mails from INBOX to shared, this move-operation should fail with a reasonable error-message. If the local quota of a mail user is exceeded, new mails should be rejected/delayed, regardless of the shared quota-value (e.g., shared quota exceeded, but no local mails [new mail-account], mails should be delivered to INBOX). Sieve-filters are not a problem, we do not allow user-specific sieve-rules (managesieve is disabled). Hopefully, I could explain my issues to you. Our current dovecot-configuration is attached to this mail, any help would be gladly appreciated. If additional configuration-values/information is needed, I'll happily provide them, if possible. best regards, Anton Dollmaier > # 1.1.13: /etc/dovecot/dovecot.conf > # OS: Linux 2.6.26-1-686 i686 Debian 5.0.1 > log_timestamp: %Y-%m-%d %H:%M:%S > protocols: imap imaps pop3s pop3 > listen: *, [::] > ssl_cert_file: /etc/dovecot/dovecot.pem > ssl_key_file: /etc/dovecot/dovecot.pem > disable_plaintext_auth: no > login_dir: /var/run/dovecot/login > login_executable(default): /usr/lib/dovecot/imap-login > login_executable(imap): /usr/lib/dovecot/imap-login > login_executable(pop3): /usr/lib/dovecot/pop3-login > mail_max_userip_connections(default): 25 > mail_max_userip_connections(imap): 25 > mail_max_userip_connections(pop3): 10 > first_valid_uid: 249 > mail_access_groups: poponly > mail_privileged_group: poponly > mail_location: maildir:~/Maildir:INDEX=~/index:CONTROL=~/control > mail_debug: yes > mail_executable(default): /usr/lib/dovecot/imap > mail_executable(imap): /usr/lib/dovecot/imap > mail_executable(pop3): /usr/lib/dovecot/pop3 > mail_plugins(default): quota imap_quota acl > mail_plugins(imap): quota imap_quota acl > mail_plugins(pop3): quota acl > mail_plugin_dir(default): /usr/lib/dovecot/modules/imap > mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap > mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 > imap_client_workarounds(default): netscape-eoh > imap_client_workarounds(imap): netscape-eoh > imap_client_workarounds(pop3): > pop3_client_workarounds(default): > pop3_client_workarounds(imap): > pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh > namespace: > type: private > separator: . > inbox: yes > list: yes > subscriptions: yes > namespace: > type: private > prefix: INBOX. > hidden: yes > subscriptions: yes > namespace: > type: public > separator: . > prefix: shared. > location: maildir:/var/mail/shared/%d/:INDEX=~/shared > list: yes > auth default: > verbose: yes > debug: yes > debug_passwords: yes > passdb: > driver: sql > args: /etc/dovecot/dovecot-sql.conf > userdb: > driver: sql > args: /etc/dovecot/dovecot-sql.conf > socket: > type: listen > client: > path: /var/spool/postfix/private/auth > mode: 432 > user: postfix > group: postfix > master: > path: /var/run/dovecot/auth-master > mode: 432 > user: vmail > group: vmail > plugin: > quota: dict:::proxy::quotadict > quota2: dict::%d:proxy::quota2dict > quota_rule: *:storage=50M:messages=1000 > quota_rule2: Trash:storage=50M:messages=100 > quota_rule3: shared*:storage=100M:messages=1000 > acl: vfile > expire: Trash 7 Spam 30 > expire_dict: proxy::expire > dict: > quotadict: mysql:/etc/dovecot/dovecot-dict-quota.conf > quota2dict: mysql:/etc/dovecot/dovecot-dict-quota2.conf (the two quota-dicts could probably be merged into one) /etc/dovecot/dovecot-sql.conf: > driver = mysql > connect = host=localhost dbname=confixx user=confixx password=p4ssw0rd > default_pass_scheme = CRYPT > password_query = SELECT CONCAT(account, '@', kunde) as user, longpw as password FROM pop3 WHERE (account='%u' and gesperrt='0' > user_query = SELECT CONCAT('/var/mail/vmail/', p.kunde, '/', p.account,'/') as home, 249 as uid, 249 as gid, CONCAT('*:storage=', p.maxkbhard) AS quota_rule, CONCAT('shared.*:storage=', k.shared_maxkb) as quota2_rule FROM pop3 AS p, kunden AS k WHERE k.kunde = p.kunde AND CONCAT(p.account, '@', p.kunde) = '%u' (quota-values in kilobytes) /etc/dovecot/dovecot-dict-quota.conf: > connect = host=localhost dbname=confixx user=confixx password=p4ssw0rd > table = dovecot_quota > select_field = current > where_field = path > username_field = username /etc/dovecot/dovecot-dict-quota2.conf: > connect = host=localhost dbname=confixx user=confixx password=p4ssw0rd > table = dovecot_quota_shared > select_field = current > where_field = path > username_field = username (tables are exactly as specified in dovecot-wiki)

[Dovecot] Segfault in ACL Plugin + user shared folders
by Markus Werner 21 Apr '09

Hi Timo, I have another problem, this time with user shared folders: User "markus" shared the folder "ForTest" to test: SETACL "INBOX/ForTest" test akxeilrwts dovecot-acl and shared-mailboxes.db have been successfully updated. As user "test" the folder (and "#User" namespace) is not visible. When I configure the shared namespace with "list = yes", the namespace and folder became visible and accessible, but lines like this are logged: Apr 7 22:08:58 asterix dovecot: IMAP(test): acl vfile: reading file /var/spool/dovecot/users/test/Maildir/.Shared/dovecot-acl Apr 7 22:09:03 asterix dovecot: IMAP(test): Invalid namespace prefix %u/ vs % Apr 7 22:09:03 asterix dovecot: IMAP(test): auth input: uid=2000 Apr 7 22:09:03 asterix dovecot: IMAP(test): auth input: gid=2000 Apr 7 22:09:03 asterix dovecot: IMAP(test): auth input: home=/var/spool/dovecot/users/markus Apr 7 22:09:03 asterix dovecot: IMAP(test): maildir: data=/var/spool/dovecot/users/markus/Maildir:INDEX=~/Maildir/index/shared/markus Apr 7 22:09:03 asterix dovecot: IMAP(test): maildir++: root=/var/spool/dovecot/users/markus/Maildir, index=/var/spool/dovecot/users/markus/Maildir, index=/var/spool/dovecot/users/test/Maildir/index/shared/markus, control=, inbox=/var/spool/dovecot/users/markus/Maildir Apr 7 22:09:03 asterix dovecot: IMAP(test): acl: initializing backend with data: vfile Apr 7 22:09:03 asterix dovecot: IMAP(test): acl: acl username = test Apr 7 22:09:03 asterix dovecot: IMAP(test): acl: owner = 0 Apr 7 22:09:03 asterix dovecot: IMAP(test): acl vfile: Global ACL directory: (null) Apr 7 22:09:03 asterix dovecot: IMAP(test): acl vfile: reading file /var/spool/dovecot/users/markus/Maildir/.ForTest/dovecot-acl Apr 7 22:09:08 asterix dovecot: IMAP(test): Invalid namespace prefix %u/ vs markus When I try to access the folder directly with "list = children" set, then dovecot segfaults.

[Dovecot] Dovecot -> Gmail (via POP Mail Fetcher)
by Neil 20 Apr '09

I'm trying to move my entire email store from my Dovecot installation (which I normally access via IMAP) into Gmail using Gmail's Mail Fetcher (which functions over POP); and I'm running into two problems: 1. Gmail only imported 78 out of 1000+ mails in my inbox, which I'm taking to mean that Dovecot is reporting only those 78 as new. How can I get Dovecot to send all mail over as new? 2. I can't be sure of this yet (since, due to #1, Gmail doesn't seem to be downloading everything), but I'm pretty sure Dovecot is only reporting my Inbox emails over POP; is there a way I can get all my mail, from all my folders, to stream in over POP? Thanks, Neil PS. I'm not leaving Dovecot entirely, I just need to have my mail in another place in case something happens to my server...

[Dovecot] Strange behaivour with extended characters
by Armando Soto Baeza 20 Apr '09

20 Apr '09

Hi there. I am using dovecot in almost all the mail servers I configure, but I have not noticed some problems till now, when I configured a server for a japanese language based customer. Now I know, the problem is not about this customer, but it seems to be a constant in all my servers (for some reason we did not noticed that before). The situation is like this. When receving mail with extended (not only japanese) characters in the subject, Outlook Express does not recognize them. Most of our users do not use OE, but most of the japanese do. This is not all. When extended chars are also in the body, they look well when the maqil still arrives, but if forwarded to another account, or when mail is an answer to another, extended characters are not well displayed. In some tests we have done, I found more or less the same is happening when using squirrelmail. The funny thing is that the problem dos not appear when using Evolution or Outlook (the MS Office component). I move some pamrs in dovecot.conf and get some results (before moving them, the problem extended to attachements), but still remains as described. Somebody has seen such a behaivour and solved it? I was thinking to change dovecot for another agent, but will be happier using dovecot. Any suggestion? Thanks in advice.

[Dovecot] [SIEVE: Redirect] Double ">" in forwarded envelop sender address => Gmail syntax error
by Toorop 20 Apr '09

20 Apr '09

Hi, Plateform: gentoo + qmail My deliver line is in a .qmail-USER file: |/var/qmail/bin/preline /usr/libexec/dovecot/deliver -f ${SENDER:-<>} -d user(a)domain.tld I notice that sieve implementation in Dovecot use double ">" for the envelop sender when there is a redirect command in sieve script. (i've tried preline -f, without -f ${SENDER:-<>},... but nothing change for the the envelop sender syntax, alway the double ">") And that fact breaks forwardin to Gmail. Gmail reply that there is a syntax error probably due to the double "<<" (<<address>> and not <address>) as we can see in the log behind: Dovecot logs: deliver(stephane@XXXX): Apr 20 16:06:44 Info: Sending a forward to <XXXX(a)gmail.com> with return path <<stephane@XXXXXX>> deliver(stephane@XXXXX: Apr 20 16:06:44 Info: msgid=<49EC816D.9090403(a)XXXXX.com>: forwarded to <XXXXX(a)gmail.com> qmail-send logs: 2009-04-20 16:06:44.877793500 info msg 14815541: bytes 1290 from <<stephane(a)XXXXX.com>> qp 17780 uid 89 2009-04-20 16:06:44.892303500 starting delivery 6356: msg 14815541 to remote XXXXX(a)gmail.com 2009-04-20 16:06:44.982424500 delivery 6356: failure: Connected_to_209.85.219.1_but_sender_was_rejected./Remote_host_said:_555_5.5.2_Syntax_error._1si7169155ewy.101/ 2009-04-20 16:06:44.982502500 status: local 0/10 remote 0/80 Is there something to do to fix that probleme ?

[Dovecot] 0 mails available even if mails in mailbox
by Raphael Thoma 20 Apr '09

20 Apr '09

Hello We are currently facing the problem, that dovecot doesn't return any messages (Pop3: +OK 0 messages) even if there are messages in the cur and new directory (maildir format). The logfile does not contain any information other than login/logout. After I deleted the dovecot.index file, all messages are available and everything works as expected. According to the wiki page [1] the main index file should be synchronized when the cur and new timestamps changed. I suppose this synchronization doesn't work correctly because the problem still existed after I changed the timestamps manually. Dovecot version: 10.0.14 Operating System: FreeBSD 7.0-RELEASE-p1 CPU Arch: amd64 Filesystem: NFS Clients: The problem exists on Pop3 and IMAP. It doesn't matter which client. I could reproduce the problem on outlook, thunderbird and even on telnet. Reproduced: +OK Dovecot ready. user user(a)domain.com +OK pass password +OK Logged in. list +OK 0 messages: After deleting dovecot.index: +OK Dovecot ready. user user(a)domain.com +OK pass password +OK Logged in. list +OK 20 messages: It seems to be a problem with the index-file from dovecot which doesn't seem to be synchronized. What could be the reason for this behaviour? How can we fix this issue for all customers? Kind regards Raphael Thoma [1] http://wiki.dovecot.org/IndexFiles

[Dovecot] dovecot deliver with sieve: Corrupted index cache file (in-memory index).cache: Broken fields for mail UID
by Mathias Gug 19 Apr '09

19 Apr '09

Hi, Running dovecot deliver 1.1.11 with a sieve script (dovecot-sieve 1.1.6 + changeset b9567e94b897) the following messages started to show up in the mail logs for some (spam) messages: deliver(mathiaz): Apr 18 19:03:06 Error: Corrupted index cache file (in-memory index).cache: Broken fields for mail UID 1 deliver(mathiaz): Apr 18 19:03:06 Error: Couldn't fix broken header unfolding deliver(mathiaz): Apr 18 19:03:06 Info: msgid=<01c9548a$f1666dfe$6c822ecf@pillarsx6>: saved mail to INBOX How serious are these? Without changeset b9567e94b897 applied deliver would actually crash and the message would be lost.

[Dovecot] Suggestion: deliver should honor mail_log_prefix
by Mike Abbott 19 Apr '09

19 Apr '09

I can set the log prefix for imap/pop3 processes using mail_log_prefix but the log prefix for deliver is hard-coded. (I'm using 1.1.13.) Deliver should either honor mail_log_prefix or have its own setting (deliver_log_prefix?). What do you think?

[Dovecot] Released Sieve v0.1.5 and ManageSieve v0.11.4 for Dovecot v1.2.rc3 and ManageSieve v0.10.6 for Dovecot v1.1.14
by Stephan Bosch 18 Apr '09

18 Apr '09

Hello Dovecot users, This is a simultaneous release of new versions of Sieve-related software for Dovecot v1.1 and v1.2. Only the Sieve implementation itself has seen significant development. The ManageSieve packages only have small fixes and the ManageSieve patches are updated as usual to match the new Dovecot releases. Changelog Sieve v0.1.5: * Ported the implementation of the Sieve include extension to the latest draft. This means that the import and export commands are replaced by a new command called global. The import and export commands are now DEPRICATED and are mere aliases for the global command. The new specification also adds the :once modifier to the include command. The also newly specified global.* variable namespace is not implemented yet as support for variable namespaces is currently missing. * Did a major rework of the multiscript support for better error handling and made sure that persistent global scripts (sieve_before/sieve_after) are always executed, even when the user does not have a script of his own and a global default is missing. + Provided basic support for the environment extension. Currenly, the name, version and host items are useful. Others are pending. + Improved error message that is presented when an unknown Sieve extension is provided as argument to the require command. It now notifies the user that Sieve core commands do not need to be specified in require. - Fixed bug in includes at levels deeper than one. - Fixed bug in address matching that was caused by the failure to handle group specifications. In Dovecot, these are marked by address items with NULL elements, which causes a segfault if not considered. The group 'undisclosed-recipients:;' in particular triggered this bug. Bug reported by Bernhard Schmidt. Changelog ManageSieve v0.11.4 (Dovecot v1.2.rc3): * Adjusted to changes in the Dovecot signal handler API. Changelog ManageSieve v0.10.6 (Dovecot v1.1.14): - Fixed small problems in the login proxy support. -- The releases are available as follows: Sieve for Dovecot 1.2: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.5.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.5.tar.gz.sig ManageSieve for Dovecot v1.2 (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.4.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.4.tar.gz.s… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.rc3-managesieve-0.11.4.diff… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.rc3-managesieve-0.11.4.diff… ManageSieve + patch for Dovecot v1.1 (package + patch): http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.6.tar.gz http://www.rename-it.nl/dovecot/1.1/dovecot-1.1-managesieve-0.10.6.tar.gz.s… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.14-managesieve-0.10.6.diff.… http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.14-managesieve-0.10.6.diff.… -- Have fun testing the new releases and don't hesitate to notify me when there are problems.

[Dovecot] Mail replication
by Renaud Allard 18 Apr '09

18 Apr '09

Hello, I am running an asynchronously replicated mail setup. 2 servers are each running an smtp server which uses dovecot as the LDA. I am using unison to replicate mail files between servers. Before, I was using Maildir format and after reading so much good papers about the very good performance of dbox format, I decided to switch to dbox. However, I now have a very annoying problem, as mails are created with names like u.1234 and numbers are following each others. So, if there is for example a mail stored as u.1001 on both servers, and now 2 mails arrive at about the same time, 1 on each server. Then, they will both be created as u.1002, that means unison will encounter a conflict as both files are different. So my question would be, is there a way to tell the servers to increment by 2 instead of 1 and have each an offset (like you can do with mysql with auto incrementing tables for example)? That way, with former example, one mail would be stored as u.1002 and the other as u.1003. Thanks

[Dovecot] Logging to see exactly all IMAP commands?

[Dovecot] Feature Request: Control over IMP IDLE 'OK Still Here' message timings
by Robert Goldsmith 18 Apr '09

18 Apr '09

Hi all, I would like to make a feature request regarding IMAP Idle support. Currently when a client triggers Idle support, Dovecot then sends 'OK Still Here' messages every 2 minutes. This is apparently to prevent NAT systems killing the tcp connection and disconnecting the client. However, while this may be fine for desktop clients, this rapidly drains the battery life of mobile clients such as phones. Unfortunately, the timing control on this behaviour is a c define at the top of cmd-idle.c and is only adjustable at compile-time. I have experimented with this define and find a timeout of 20 minutes between 'OK' messages is perfectly adequate for my system setup and results in a significant battery saving for my Nokia 6120c (increasing from ~ 6 hours to ~ 55 hours from full charge to low battery warning). Therefore, can you please make the timeout changeable from the config file, even if it defaults to the current 2min timing, so admins supporting mobile users can balance battery life with a need to prevent killed tcp connections. Thanks Robert Goldsmith --- GnuPG public key: http://www.Far-Blue.co.uk

[Dovecot] Shared folders and subscriptions
by Markus Werner 18 Apr '09

18 Apr '09

Hi, I've got a problem with user shared folders and subscriptions. When I try to subscribe a folder, dovecot returns "OK Subscribe completed", but the newly subscribed folder is not listed with LSUB: a1 login test(a)example.com ******* a1 OK [CAP..... a2 list "" "*" * LIST (\HasChildren) "/" "INBOX" * LIST (\Noselect \HasChildren) "/" "#User" * LIST (\Noselect \HasChildren) "/" "#User/markus(a)example.com" * LIST (\HasNoChildren) "/" "#User/markus(a)example.com/ForTest" a3 subscribe "#User/markus(a)example.com/ForTest" a3 OK Subscribe completed. a4 lsub "" "*" * LSUB (\Noselect) "/" "#User/markus(a)example.com" Dovecot is 1.2-rc3, namespace configuration as follows: namespace private { separator = / prefix = INBOX/ inbox = yes subscriptions = yes } namespace public { separator = / prefix = "#Shared/" location = maildir:/var/spool/dovecot/sharedfolders:INDEX=~/Maildir/index/public:CONTROL=~/Maildir/control/public subscriptions = yes } namespace shared { separator = / prefix = "#User/%%u/" location = maildir:%%h/Maildir:INDEX=~/Maildir/index/shared/%%u:CONTROL=~/Maildir/control/shared subscriptions = yes list = yes } I tried without CONTROL= directory in the shared namespace, but that made no difference.

[Dovecot] Sieve "redirect"
by James Butler 18 Apr '09

18 Apr '09

Is there an alternative to the "redirect" Sieve capability? For example: if header :contains "Subject" "Listserv" { redirect "list-user1(a)example.com"; redirect "list-user2(a)example.com"; redirect "list-user3(a)example.com"; stop; } How can I do the above without using "redirect"? Unfortunately, "redirect" seems to be unsupported by Dovecot. Thank you. James

[Dovecot] Address Extensions with System Users
by Jeff Grossman 18 Apr '09

18 Apr '09

I am using Dovecot 1.2RC2 with Postfix 2.5.5. Everything is running fine. I would like to start using address extensions and have e-mail automatically filtered into folders based on the folder name after the "+" in the e-mail address. I only use system users, no virtual users. I have Deliver configured in main.cf as: mailbox_command = /usr/local/libexec/dovecot/deliver Everything I can find about setting this up applies to virtual users which I do not have. How do I get Deliver to recognize the address extension. I am sure it is easy, and I apologize for not finding the answer out myself. Here is a copy of my dovecot -n output: # 1.2.rc2: /usr/local/etc/dovecot.conf # OS: Linux 2.6.29-1-amd64 x86_64 Debian squeeze/sid base_dir: /var/run/dovecot/ protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/certs/stikman-godaddy.crt ssl_key_file: /etc/ssl/private/stikman-godaddy.key ssl_cipher_list: ALL:!LOW:!SSLv2 disable_plaintext_auth: no login_dir: /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 mail_location: maildir:~/Maildir 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_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 auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd plugin: sieve: sieve

[Dovecot] Setup Question
by Jeff Grossman 17 Apr '09

17 Apr '09

I really want to try and get this plus addressing working correctly with Dovecot and Postfix. After doing some reading I think I am going to change my Postfix setup from mailbox_command to mailbox_transport. I have a few questions to make sure I am thinking correctly. All of my users are system users. Their mail is delivered directly to their "/home/<user>/Maildir" directory. Everything works great and I have no problems. Here is what I am thinking of doing. 1. Create a new vmail user and group. 2. Have all mail delivered for each user to the "/home/vmail/<user>/" directory. All mail will be owned by vmail, but that is okay since Dovecot is the only thing touching the mail files anyway. 3. Change the mail_location setting in dovecot.conf to "mail_location = /home/vmail/%u 4. Uncomment the auth_socket_path = /var/run/dovecot/auth-master setting in dovecot.conf 5. Switch Postfix's main.cf to use "mailbox_transport = dovecot" and put the following line in master.cf: 1. dovecot unix - n n - - pipe flags=DR user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient} -n -m ${extension} 6. Copy the current users mail to the new vmail location. What is the best way to copy it preserving date and time stamps on the mail? Did I cover all of the steps are am I missing something? Here is a copy of my current dovecot -n output. Thanks for any help you can offer me. # 1.2.rc3: /usr/local/etc/dovecot.conf # OS: Linux 2.6.29-1-amd64 x86_64 Debian squeeze/sid base_dir: /var/run/dovecot/ protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/certs/ssl.crt ssl_key_file: /etc/ssl/private/ssl.key ssl_cipher_list: ALL:!LOW:!SSLv2 disable_plaintext_auth: no login_dir: /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 mail_location: maildir:~/Maildir 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_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 auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd plugin: sieve: sieve

[Dovecot] Active Directory LDAP authentication fails after a time
by noahisaac 17 Apr '09

17 Apr '09

Hi - I've got Dovecot version 1.0.7 running on a CentOS 5.2 machine. It's serving pop, imap and imaps and authenticating against an Active Directory machine. This all works fine at first, but after about two weeks or so, dovecot's authentication against AD starts to fail. All of dovecot's authentication attempts time out. I also have postfix on the same machine authenticating against the same AD, and it does not seem to experience this issue. If I restart dovecot, the authentication starts working again. I've gone over /var/log/maillog, but I don't see anything particularly useful. The only thing I really see is: dovecot: IMAP(noah): Disconnected for inactivity Here's some of the relevant portions of my configs: dovecot.conf auth default { mechanisms = plain passdb ldap { args = /etc/dovecot-ldap.conf } passdb passwd-file { args = /etc/dovecot/passdb master = yes } userdb static { args = uid=vmail gid=vmail home=/home/vmail/%u } user = root } dovecot-ldap.conf hosts = admachine.domain.com base = dc=domain,dc=com ldap_version = 3 auth_bind = yes auth_bind_userdn = DOMAIN\%u Does anybody have any ideas about why this is happening, or maybe just an idea about how to better troubleshoot it? If you need any more info, I'll be happy to provide it. Can I tell dovecot to be a little more verbose with it's log entries (I've already got auth_debug set to yes, but I'm not getting very much info)? Thanks!

[Dovecot] SELinux and "i_stream_read() failed: Permission denied"
by James Butler 17 Apr '09

17 Apr '09

Not a problem ... sharing a solution (this time)! Please correct my understanding of the process, if required. "i_stream_read() failed: Permission denied" is an error message generated when a large-ish file (>128kb in my case) is attached to a message that has been passed to Dovecot's deliver program when SELinux is being enforced. In my case, these messages are first run through Spamassassin, then passed to deliver, however the SELinux policy that is being violated relates to deliver, and not to Spamassassin, even though I do NOT generate the errors WITHOUT running Spamassassin. I'm not going to guess as to why that is. The policies below resolve the issue, and now large-ish (even LARGE) attachments come through without a whimper with Postfix+Spamassassin+Dovecot. The problem is that deliver is not running with the correct SELinux policy to be able to write to the global /tmp directory (in my case, after receiving the big attachment from SA), even if that directory's permissions allow it. (Bless you, SELinux!) Small-ish file attachments do not trigger this deliver functionality. Here's a complete error message, and its subsequent errors in the course of delivering a large-ish message+attachment: =================================================== deliver(user): unlink(/tmp/dovecot.deliver.. \ 1239836047.9469.46242b1037005551) failed: Permission denied deliver(user): copy: i_stream_read() failed: Permission denied deliver(user): read(mail, uid=1) failed: Permission denied deliver(user): read(mail, uid=1) failed: Permission denied deliver(user): msgid=: save failed to INBOX: Internal error occurred. \ Refer to server log for more information. [2009-04-15 17:54:07] =================================================== This is the final error series received before the policies were finally updated, and shows an error during deliver's attempt to "unlink()" (remove) the temporary file. Previous errors occurred during attempts to "stat()" and "creat()" (sic) the temporary files. Basically, the "dovecot_deliver_t" context needs to be able to create, read, write and remove files in the /tmp directory ("tmp_t" context). Below, I am pasting my "local_postfix.te" SELinux policy file. It includes instructions for using it, and for figuring out how to do other SELinux policy adjustments on your own. This is my COMPLETE Postfix+Dovecot SELinux policy group. I also have policies for Spamassassin, if anyone wants them. If you are running Sendmail or another MTA instead of Postfix, you can build on what you find below and establish your own policies. I hope this proves useful. Again, please feel free to correct any misunderstandings I may be promoting with this message. Use at your own risk, please! No guarantees ... it just worked, for me.

[Dovecot] UW-IMAP migration to namespaces
by Jernej Porenta 17 Apr '09

17 Apr '09

Hello, I am trying to migrate existing UW-IMAP installation to dovecot 1.1.14 and I am having troubles with namespaces. As you know UW-IMAP allows full system access to home directory of a user and you can set up dovecot to do that as well, but I would like to use namespaces. If I set my namespaces like this: namespace private { separator = / prefix = inbox = yes location = mbox:~/:INBOX=~/.mailbox hidden = yes list = yes } namespace private { separator = / prefix = mail/ location = mbox:~/mail prefix = mail/ hidden = yes } Everything is working fine, but I am seeing also all other files in home directory of a user, but this is annoying if you have users with public_html folder with millions of files in it. Dovecot indexing makes index.log file for every file seen in namespace, so you have several million index files for files that are not mailboxes. So I was wondering is there a way to skip certain directories in namespaces or a way to setup namespaces in a way, that you would have: - INBOX in home directory - some folders in home directory (via .subscriptions) - some folders in %h/mail/ directory - and not seeing all other files/directories in home dir Thanks in advance, regards, Jernej

[Dovecot] Multiple instances and/or separate certificates per email address
by Simon L Jackson 17 Apr '09

17 Apr '09

Hi, We have a mail server with multiple instances of Postfix each listening on a different IP address to create a set of virtual mail servers. There are various reasons why separate instances of Postfix seems to work best to achieve this goal, but I wont divert into that discussion here. I would like so match this with Dovecot. The listening side isn't a problem as Dovecot can listen on multiple explicit IP addresses. However, we would prefer a separate SSL certificate for each virtual mail server i.e. for each IP address. Would it be better to have multiple instances of Dovecot on the server (not sure what the issues might be with this) or would it be better/easier to be able to specify separate SSL certificates for each listen address, since there isn't any other reason I can see to have multiple instances. Any thought? Is there a way to do this now or would this be a new feature request?

I was already going to report a bug with rc2 where the server crashed when a client tried to access a Maildir folder with wrong permissions. After installation of rc3 the server correctly reports the wrong permissions and keeps running: IMAP(user1): stat(/var/spool/mail/user1/Maildir/tmp) failed: Permission denied (euid=12807(user1) egid=200(grp1) missing +x perm: /var/spool/mail/user1/Maildir) Great work, thanks Timo! -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

[Dovecot] v1.1.14 and v1.2.rc3 released
by Timo Sirainen 17 Apr '09

17 Apr '09

http://dovecot.org/releases/1.1/dovecot-1.1.14.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.14.tar.gz.sig http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc3.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc3.tar.gz.sig Fixed lots of bugs in v1.2 related to shared mailboxes and virtual mailboxes. Keep on testing and sending bug reports and hopefully we'll get v1.2.0 release out soon. :) Also v1.3 branch has started and it's coming along nicely. Multi-dbox is working and looks like its performance is very nice. LMTP server is basically implemented, except master process doesn't start it. Adding the master code started becoming so annoying that I think I'll finally finish the master process rewrite, or at least the most important parts of it. So looks like v1.3 might become v2.0 after all. v1.1.14 2009-04-16 Timo Sirainen <tss(a)iki.fi> * IMAP: Don't allow APPEND to specify INTERNALDATE more than 2 hours into future. With Maildir future INTERNALDATEs may mess up incremental backups. - Date: header was always being added to cache file when saving messages, even if clients didn't really want it. This caused POP3-only users to have dovecot.index.cache file unneededly. - Character set conversion in specific mails may have caused Dovecot to allocate all the available memory (in default configuration dying after having allocated 256 MB). This happened only while searching messages. - Message address parser didn't handle empty group:; correctly. - imap/pop3-login: Don't crash when shutting down and destroying clients. - deliver wasn't using mail_access_groups setting. - mbox: When doing autodetection, if mbox didn't find an existing mail directory it just went and created it anyway, instead of failing the storage creation. - Fixed some error handling in maildir and index code. v1.2.rc3 2009-04-16 Timo Sirainen <tss(a)iki.fi> * IMAP proxy no longer simply forwards tagged reply from remote authentication command. It's now done only if the remote server sent a [resp-code], otherwise all failure strings are converted to Dovecot's "Authentication failed." to make sure that if remote isn't using Dovecot it won't reveal user's existence. + Quota roots can now specify which namespace's quota they're tracking. This is probably the most useful for giving public namespaces a quota. + Added imap_idle_notify_interval setting. - Fixes to shared mailbox handling - Fixes to virtual mailboxes - Fixed compiling with some FreeBSD and NetBSD versions - THREAD REFS still might have returned one (0) at the beginning. - deliver wasn't using mail_access_groups setting. - Fixed some error handling in maildir and index code.

[Dovecot] Postfix, Dovecot SASL and Entourage smtps authentication fails.
by Mart Pirita 17 Apr '09

17 Apr '09

Tere. Recently just migrated from Sendmail 8.14.3 to Postfix 2.5.6 and switched from Cyrus-sasl 2.1.22 to Dovecot 1.1.13 sasl, all are compiled from source and I have used Dovecot for a long time, since alpha versions. Everything worked well for Outlook Express, Outlook and Thunderbird clients, but Microsoft Entourage 2004 or 2008 clients smtps fails - "Authentication failed because Entourage doesn't support any of the available authentication methods." Similar case like - http://archives.neohapsis.com/archives/postfix/2008-09/thread.html#145 I tried everything, the config is like described in Postfix and Dovecot sites - http://wiki.dovecot.org/HowTo/PostfixAndDovecotSASL I also tried in main.cf smtpd_sasl_security_options =forward_secrecy like described in http://www.postfix.org/postconf.5.html#smtpd_sasl_security_options But none helped. So I switched back to Cyrus-sasl and Entourage works well like before with sendmail. I started to search what may be the reason, and seems with Dovecot sasl Postfix wont advertise needed stuff in ehlo: With Cyrus: telnet localhost 25 Trying 127.0.0.1... Connected to localdomain.localhost. Escape character is '^]'. 220 my.host.ee ESMTP EHLO example.com 250-my.host.ee 250-PIPELINING 250-SIZE 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN starttls 220 2.0.0 Ready to start TLS With dovecot: telnet localhost 25 Trying 127.0.0.1... Connected to localdomain.localhost. Escape character is '^]'. 220 my.host.ee ESMTP EHLO example.com starttls 220 2.0.0 Ready to start TLS Setting with Cyrus in main.cf smtpd_tls_auth_only = no gives even more but still nothing with Dovecot: telnet localhost 25 Trying 127.0.0.1... Connected to localdomain.localhost. Escape character is '^]'. 220 my.host.eeESMTP EHLO example.com 250-my.host.ee 250-PIPELINING 250-SIZE 250-ETRN 250-STARTTLS 250-AUTH PLAIN LOGIN 250-AUTH=PLAIN LOGIN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN So is this a Entourage or Dovecot or Postfix bug? I really like to drop the Cyrus and use only Dovecot sasl. Any hint is welcome. -- Mart

[Dovecot] public folders question
by Xueron Nee 17 Apr '09

Hi, Shared folders is ok now. and when I create a public folder follow the doc http://wiki.dovecot.org/SharedMailboxes/Public, I can not get the boxes listed. namespace: type: public separator: / prefix: public/ location: maildir:/home/data/public:INDEX=~/Maildir/public list: children # ls /home/data/public/ -a . .. dovecot-shared .test1 .test2 .test3 And then, I checked the shared folders created by 'setacl' command, and add a dovecot-acl-list file in the root public folder, ok, I got it. # cat /home/data/public/dovecot-acl-list 1239108915 test1 so, 'dovecot-acl-list' should be created manually or any other methods?

[Dovecot] Is there any more detailed docs about dict configuration
by Xueron Nee 17 Apr '09

17 Apr '09

Hi, I am looking for some help on dict configration. I'm trying to config shared and public mailbox, and use sql as acl backend. Here is my config: table: CREATE TABLE `shared_dict` ( `id` int(10) NOT NULL AUTO_INCREMENT, `from_user` char(50) NOT NULL, `to_user` char(50) NOT NULL, `status` int(10) NOT NULL DEFAULT '1', PRIMARY KEY (`id`), KEY `from_user` (`from_user`), KEY `to_user` (`to_user`) ) dovecot-dict-sql.conf map { pattern = shared/shared-boxes/user/$from/$to table = shared_dict value_field = status fields { from_user = $from to_user = $to } } dovecot.conf acl_shared_dict = proxy::shared_dict It works, and when i use 'setacl', it can add a record. All I want are some more detailed docs about the `pattern' line, and such as how to add a `group' function. :) Detailed on quota/expire dict configration are welcome, too. :) Thanks! -- Xueron Nee http://www.xueron.com

[Dovecot] Public mailboxes configuration to receive mails
by Didier Faugeron 17 Apr '09

17 Apr '09

Hello, I would like to know how to use Public mailboxes in my Dovecot environment (dovecot 1.2.beta4) Currently my dovecot server is only used for mailbox user. The Postfix master.cf is configured with the following line: "dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -d ${user}" Both dovecot and postfix use LDAP requests for authentication and users data retrieving. However I don't use userdb database to get the users home directory but an userdb static instruction : "args = uid=vmail gid=vmail home=/data/maildir/%1Lu/%Lu allow_all_users=yes" I have configured my dovecot.conf to create a namespace Public, and it works fine: an user who have read/write access(ACL) to a public mailbox can subscribe to it and read/copy mails. My problem is to deliver mails in this public mailbox. I don't know how to do it. Therefore, first question: is it possible to deliver mails to a public mailbox through the LDA/Postfix ? If yes, please could you tell me how to configure LDA/Postfix and Dovecot in order to accept and deliver mails to users mailboxes and to public mailboxes ? I assume that the main modifications should be done in the master.cf of Postfix. Could you please specify and clarify what modifications are required ? Find below my dovecot -n output and dovecot-ldap.conf. Thank you in advance for your help and your feedback.

[Dovecot] Could sharing a folder with other users cause a loss of emails?
by Alfred Nutile 17 Apr '09

17 Apr '09

we are trying to figure out how and email box is not empty. All we did was /mail/user1 /mail/user2 /mail/shared ln -s /mail/shared /mail/user1/shared ln -s /mail/shared /mail/user2/shared Perms are fine and people where dropping emails in here fine. We added a third one and the user also right clicked in their IMAP client and added a subfolder. It was around that time they where gone. Could any of these actions cause that? PS it is not a mbox layout. Thanks!

[Dovecot] Coredump using virtual folder.
by Matthias Rieber 17 Apr '09

Hi, I'm using dovecot 1.2rc2 and I have the following issues with the virtual folder: 1. The virtual folders are flagged with \Noselect and at least thunderbird does not offer to select them. Adding them to the subscriptions file works fine and the folder can be used after that. 2. Two basic virtual work just fine like: $ cat virtual/all/dovecot-virtual INBOX INBOX.Ordner.work.archive.* all and $ cat virtual/unseen/dovecot-virtual INBOX unseen But the third one does not work: $ cat virtual/talk/dovecot-virtual virtual.all inthread x-references2 x-mailbox INBOX The IMAP Client says Unkown server error, the server logs look like this: ... dovecot: Info: IMAP(matthias): virtual: data=~/Maildir/virtual dovecot: Info: IMAP(matthias): fs: root=/home/matthias/Maildir/virtual, index=, control=, inbox= dovecot: Info: IMAP(matthias): Namespace INBOX.: Using permissions from /home/matthias/Maildir: mode=0700 gid=-1 <access happens here> dovecot: Info: IMAP(matthias): Loading modules from directory: /usr/local/lib/dovecot/imap dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib20_fts_plugin.so dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib20_virtual_plugin.so dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib21_fts_squat_plugin.so ... kind regards, matthias

[Dovecot] virtual domains with SQL auth + ntlm (winbind) auth for one of them...
by Tomasz Lutelmowski 16 Apr '09

16 Apr '09

Hello ! Is it possible to configure dovecot so it can use SQL authentication for set of domains, and ntlm authentication for one domain? In other words, I would like to authenticate all users (with user(a)domain.com as login) in SQL server, and if not found, then strip @windomain.com from login and fallback to pam->winbind authentication. So far i have in my dovecot.conf: auth_default_realm = windomain.com mechanisms = plain passdb sql { args = /etc/dovecot/dovecot-sql.conf } passdb pam { } passdb passwd { } userdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb passwd { } userdb prefetch { } in pam.d/dovecot : auth required pam_nologin.so auth include system-auth-winbind account include system-auth-winbind session include system-auth-winbind With this configuration I can authenticate all users for virtual domains with logins user(a)domain.com - ok, then it fallbacks to pam - ok, but then it returns error (winbind uses only "user" or "DOMAIN\user" as login). After I set auth_username_format = %n I get opposite situation - I can authenticate users with pam, but I can't with SQL (it requires user@domain as login field). Unfortunately auth_default_realm = windomain.com is a must have (and most of the windows clients uses user(a)windomain.com as login anyway). Please help, I'm banging my head against keyboard since 3 days but still no idea how to do it. Best regards, Tomek

[Dovecot] dovecot SASL + Postfix no IMAP or POP3
by Roderick A. Anderson 16 Apr '09

16 Apr '09

A customer is suffering with an older version of a Windows "Mail Server" software that does not permit connections to _other_ ports (25 only). Several of the domains they host have users who's ISPs block port 25 so they can not send mail. They'd like to set up an outbound (relay?) SMTP server for those customers using per user(a)domain.tld authentication. Since I personally use Postfix with dovecot SASL I'd prefer doing the same for them. The only issue I see is how to "disable" IMAP and POP3 and use only the SASL authentication feature. I read that Timo is thinking to _someday_ :-) separate the SASL authentication from the rest of Dovecot, but in the mean time can I just leave out the IMAP and POP3 stuff from dovecot.conf, or is there a disable option? Of course I'll clamp the IMAP and POP3 ports down with iptables but it would be nice knowing Dovecot would just say go away or ignore those connections. Is anyone doing this or have any suggestions, thoughts, or ideas about it? \\||/ Rod --

[Dovecot] INBOX lost in virtual namespace
by Xueron Nee 16 Apr '09

16 Apr '09

Hi, I have set a virtual namespace to create Virtual POP3 INBOX follow: http://wiki.dovecot.org/Plugins/Virtual dovecot.conf: mail_location = maildir:~/Maildir # default namespace namespace private { separator = / prefix = list = yes hidden = no subscriptions = yes } # virtual mailbox, for pop3 namespace private { separator = / prefix = virtual/ location = virtual:~/Maildir/virtual:LAYOUT=maildir++ list = no hidden = yes } # Copy of the default namespace. We'll use this in dovecot-virtual file. namespace private { separator = / prefix = secret/ list = no hidden = yes subscriptions = no } # cat ~/Maildir/virtual/.INBOX/dovecot-virtual secret/* all but, the INBOX lost in secret/ namespace :( When list in IMAP: a1 list "" "*" * LIST (\HasNoChildren) "/" "Sent" * LIST (\HasNoChildren) "/" "Spam" * LIST (\HasNoChildren) "/" "Junk" * LIST (\HasNoChildren) "/" "Draft" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "INBOX" a1 OK List completed. a1 list "secret/" "*" * LIST (\HasNoChildren) "/" "secret/Sent" * LIST (\HasNoChildren) "/" "secret/Spam" * LIST (\HasNoChildren) "/" "secret/Junk" * LIST (\HasNoChildren) "/" "secret/Draft" * LIST (\HasNoChildren) "/" "secret/Trash" a1 OK List completed. INBOX lost, So, the virtual namespace for POP3 cannot see the messages in IMAP's INBOX. Am I doing anything wrong? Thanks.. -- Xueron Nee http://www.xueron.com

[Dovecot] help with ldap config

Hi, I've been using courier with ldap and I'm trying to configure dovecot to do the same. I'm not exactly sure how to setup the ldap binds and filters...

Oh, that was fun. Making the change below resulted in mail getting deferred with "Fatal: destination user parameter (-d user) not given" ... which apparently is caused by running deliver as 'root'! (http://archive.netbsd.se/?ml=dovecot-general&a=2008-02&t=6558196) So I am back to: -rwxr-xr-x 1 root dovecot 4044835 2009-04-03 13:52 deliver which doesn't produce the error and delivers the mail. Still no joy with Postfix+Spamassassin+Dovecot. This is unbelievably hard to get going. I started with the default installations of everything on a brand new system. I only made minimal changes as indicated by the docs. Then I made small changes as indicated by this and other mailing lists. I always reverted back to the original defaults between each effort. Now I'm just stumped. I'm not a newbie ... I've been administrating public servers for over 10 years, and using and working on the Internet since 1968! This is just the first time I've tried to use Postfix+Spamassassin+Dovecot. Previous installations have all used Sendmail+Spamassassin+Dovecot with zero issues. I want the benefits of using the Maildir storage system, but the past two weeks of trying to get this going are making me question whether that benefit is worth it. Can anyone please post their successful Postfix+Spamassassin+Dovecot setup for me to learn from? I would really appreciate it.

[Dovecot] auth-master: Permission denied [sigh]

I've been messing with this for too long, now, and I'm blind to whatever's wrong. Or I'm simply being dense. Either way, I need help with a common issue. I'm trying to get Postfix+Spamassassin+Dovecot going on Fedora 10. (I'll get back to the global Sieve thingy soon, but I need to get this going, first.) When using the simple: mailbox_command = /usr/local/libexec/dovecot/deliver everything is cool, except there's no Spamassassin involvement, obviously. The problem shows itself when the Spamassassin user hands off to the recipient user and Deliver + the recipient user tries to access /var/run/dovecot/auth-master. Thank you for any insight you can provide. /var/run/dovecot: 755 root:dovecot /var/run/dovecot/login: 750 root:dovecot /var/run/dovecot/auth-master: 750 root:dovecot (I think. auth-master is a temporary file?

[Dovecot] uw-imap to dovecot conversion tool
by Joe Pruett 14 Apr '09

14 Apr '09

i plan to switch from uw-imap to dovecot on a couple of medium size systems and so i have written a conversion tool that understands mbox, mbx, and mix formats and converts to maildir format while trying to preserve uid info, keywords, flags, subscriptions, etc. it seems to work for me now, but i think some feedback might be useful. so if you have some files to convert and a desire to help, please download: http://www.spiretech.com/~joey/uw2dovecot.pl and give it a whirl. it is very sparsely documented right now but isn't too complex (yet). by default it copies your INBOX, mail dir, and .mailboxlist info into Maildir. those filenames can be overridden. i'd suggest running with -v to watch it. it requires that the output directory not exist before starting, so it should be relatively safe. it doesn't lock any files being read, so an active uw tree could cause it indigestion. it's designed to run while inbound mail and pop/imap sessions are disabled. it uses a few perl modules, but they should be standard with perl itself. it does do everthing in memory, so the largest message you have will be in memory and will be duplicated at least once as crlf pairs are replaced. also, this assumes you'll change the uid format in dovecot.conf to %08Xu%08Xv so that it doesn't change uids for the clients. send feedback to me and cc the list if you feel it useful. once this is stable, i'll get it added to the dovecot wiki.

[Dovecot] Handling ENFILE
by Mike Abbott 14 Apr '09

14 Apr '09

My mail server consumed all of its configured file table slots and started returning ENFILE ("Too many open files in system") for many operations. This wreaked havoc with dovecot-1.1.13. Here are some areas where dovecot should detect and more gracefully handle ENFILE error returns: 1. Deliver should report an error more helpful than "Unknown internal error" when fdatasync_path fails: deliver(user): Apr 10 14:53:20 Error: fdatasync_path(/Volumes/MailData/ user/new) failed: Too many open files in system deliver(user): Apr 10 14:53:20 Info: msgid=<...>: save failed to INBOX: BUG: Unknown internal error 2. Index files should not be fscked when they could not be opened due to ENFILE: Error: IMAP(user): open() failed with index file /Volumes/MailData/ user/.Deleted Messages/dovecot.index: Too many open files in system Warning: IMAP(user): fscking index file /Volumes/MailData/ user/.Deleted Messages/dovecot.index 3. Dovecot should not crash when mail transaction logs become corrupt, or appear to have become corrupt due to ENFILE.

[Dovecot] Issue with converting users from cyrus user.domain.com
by Preston Lord 13 Apr '09

13 Apr '09

I have been using cyrus for the past 6 years, but it is a pain to config. So ... I just installed dovecot 1.0.15 on a new debian 4r7 box. In cyrus we were using usernames as "user.domain.tld". In dovecot I realize I can: auth_username_translation = .@ But this converts user.domain.tld to user@domain@tld which of course fails. Is there a regex or something I can apply to pull this off? I also tried auth_username_format = %n.%d But I think this does the opposite of what I need. Any help is GREATLY appreciated. Thanks in advance P.

[Dovecot] deliver vs lda
by Timo Sirainen 12 Apr '09

12 Apr '09

deliver is the binary name. but it's configured inside protocol lda {} section. This is getting annoying, any thoughts on what would be a good unifying name? a) deliver binary, protocol deliver {} b) lda binary, protocol lda {} c) dovecot-lda binary, protocol lda {} d) mda binary, protocol mda {} e) dovecot-mda binary, protocol mda {} f) something else? In any case protocol lda {} would work for a while longer for backwards compatibility. c) and e) choices also makes me think if e.g. imap and imap-login should be called dovecot-imap and dovecot-imap-login instead. People have had trouble finding them since ps|grep dovecot doesn't find them..

tonight dovecot 1.2beta4 crashed for the first time with an assertion failed. See attached log file. Around that time nobody was logged in into dovecot and there were no other mail deliveries going on.

[Dovecot] Postfix + Dovecot + Sieve + SpamAssassin
by Sascha Scandella 10 Apr '09

10 Apr '09

Hello Until now I used Postfix in combination with Procmail and Dovecot. I am convinced that the Dovecot Sieve plugin is a much more elegant solution. So I changed to Postfix + Dovcecot Deliver + Dovecot + Sieve. If I understood correctly I cannot call other applications within a Sieve script. Until now I used Procmail to filter Spam Messages with SpamAssassin. Is there a possibility to filter spam messages before/after Dovecot deliver. I want to use the users .spammassassin user_prefs located in their home folder. I suppose if I use a content filter in Postfix this is to early, since the user is not known at that moment. Or am I wrong? Any help is highly appreciated. Best regards, Sascha

[Dovecot] dbox problem
by Xueron Nee 09 Apr '09

09 Apr '09

Hi, I have just tested the dbox format mailbox, it works fine. But when I create dir through imap with `create` command, it only creates the dir onder ~/dbox/mailboxes, such as ~/dbox/mailboxes/newfolder. There was no `dbox-Mails` dir created. So the newfolder was 'noselect'. But the new folders created by `autocreate` plugin was correct. -- Xueron Nee http://www.xueron.com

[Dovecot] Indexing of mails to speed up the IMAP SEARCH command
by Tassilo Horn 09 Apr '09

09 Apr '09

Hi all, I use a local dovecot server which is synchronized with my two imap accounts using OfflineIMAP. This works very nice and is highly usable. But one thing I'd like to improve is the slow IMAP search. When I search for a string in the subjects of all messages in a mailbox using some mail client, dovecot seems to grep all the messages in there. Is there a way to let dovecot index more informations which are then used to speed up the SEARCH command? Bye, Tassilo

[Dovecot] Moving IMAP folders to NFS volume.
by Frank Bonnet 09 Apr '09

09 Apr '09

Hello Due to lack of disk space on local disks I need to move all our imap folders to a NFS volume ( NetAPP filer ) I have a question about Dovecot indexes , is it better to remove all of them before copying folders to the NFS volume and let Dovecot rebuild all indexes when users restart to access to their imap folders ? Thanks a lot.

[Dovecot] Strange behavior of header_filter_callback
by Konstantin Lepa 09 Apr '09

09 Apr '09

Hello. I asked about the problem in http://markmail.org/message/zsry62fcig5hqka3 . And I created simple example plug-in for deliver. It is attached (I don't want to paste so much code) For compile in command-line run: # DOVECOT=<path to dovecot> gmake ...send mail... ...view dovecot lda log... # gmake clean # WITH_ONLY_HEADERS=1 DOVECOT=<path to dovecot> gmake ...send mail... ...view dovecot lda log...

[Dovecot] Upgrade from 0.99.x to 1.1.x
by Wolfram Schlich 09 Apr '09

09 Apr '09

Hi! I want to upgrade a Dovecot installation from 0.99.14 to 1.1.15, so I had a look at the following wiki article: http://wiki.dovecot.org/Upgrading?action=show&redirect=UpgradingDovecot The article http://wiki.dovecot.org/Upgrading/1.0 says something about .customflags -> dovecot-keywords and .subscriptions -> subscriptions change/conversion: http://wiki.dovecot.org/Upgrading/1.0#Subscriptions http://wiki.dovecot.org/Upgrading/1.0#Keywords Do I understand it correctly that when directly upgrading from 0.99 to 1.1, Dovecot does the subscriptions renaming but not the keywords renaming and conversion, but that when I manually rename all .customflags files to dovecot-keywords, it does the format conversion of that file automatically? Is there anything else what's important to note for such an upgrade? The system is using Maildir as the mailbox format and only local storage (no NFS etc.). -- Regards, Wolfram Schlich <wschlich(a)gentoo.org> Gentoo Linux * http://dev.gentoo.org/~wschlich/

[Dovecot] Multiple use of the same LDAP attribute
by Bernhard Schmidt 09 Apr '09

09 Apr '09

Hi, we've found a weird bug (?) in Dovecot 1.1.11. Since day and age we've been running dovecot for our student mailserver, getting the location of the mailbox from a LDAP directory. We allow login and LDA with both full mail address and an internal username, so the mailbox directory is based on a LDAP attribute user_attrs = xxxMailbox=mail=maildir:/home/mailstore/%U$/Maildir:INDEX=/home/mailstore/indexes/%1U$/%U$, uidNumber=vmail, gidNumber=vmail, xxxMailQuota=quota_rule2=*:storage=%$B this worked just fine until we introduced sieve, which made us realize we did not have the home directory set at all. The obvious and easy fix (we thought) was to set the home directory based on the xxxMailbox variable as well: user_attrs = xxxMailbox=mail=maildir:/home/mailstore/%U$/Maildir:INDEX=/home/mailstore/indexes/%1U$/%U$, uidNumber=vmail, gidNumber=vmail, xxxMailQuota=quota_rule2=*:storage=%$B, xxxMailbox=home=/home/mailstore/%U$ unfortunately, after this trivial change hell froze over, because suddenly the mail variable was not set at all anymore, and since we had set mail_location = maildir:/home/mailstore/%Uu/Maildir:INDEX=/home/mailstore/indexes/%1Un/%Un (based on username) it was suddenly delivered into the wrong folder (based on the supplied username, not on the LDAP attribute). Debug from after the change: Apr 8 13:53:39 lxmhs23 dovecot: auth(default): ldap(username(a)xxx.de): user search: base=<deleted> scope=onelevel filter=<deleted> fields=xxxMailbox,uidNumber,gidNumber,xxxMailQuota,xxxMailbox Apr 8 13:53:39 lxmhs23 dovecot: auth(default): ldap(username(a)xxx.de): result: xxxMailQuota(quota_rule2=*:storage=%$B)=*:storage=1073741824B xxxMailbox(home=/home/mailstore/%U$)=/home/mailstore/1636D8B1D7916DEA/ [...] Apr 8 13:53:39 lxmhs23 deliver(username(a)xxx.de): maildir: data=/home/mailstore/USERNAME@XXX.DE/Maildir:INDEX=/home/mailstore/indexes/U/USERNAME As you can see the mail variable wasn't set by LDAP at all. We did some more tests and found a workaround, when using another LDAP (mwnid) attribute that contains the same information it works just fine user_attrs = xxxMailbox=mail=maildir:/home/mailstore/%U$/Maildir:INDEX=/home/mailstore/indexes/%1U$/%U$, uidNumber=vmail, gidNumber=vmail, xxxMailQuota=quota_rule2=*:storage=%$B, mwnid=home=/home/mailstore/%U$ Apr 8 14:18:06 lxmhs23 dovecot: auth(default): ldap(username(a)xxx.de): user search: base=<deleted> scope=onelevel filter=<deleted> fields=xxxMailbox,uidNumber,gidNumber,xxxMailQuota,mwnid Apr 8 14:18:06 lxmhs23 dovecot: auth(default): ldap(username(a)xxx.de): result: xxxMailQuota(quota_rule2=*:storage=%$B)=*:storage=1073741824B xxxMailbox(mail=maildir:/home/mailstore/%U$/Maildir:INDEX=/home/mailstore/indexes/%1U$/%U$)=maildir:/home/mailstore/1636D8B1D7916DEA//Maildir:INDEX=/home/mailstore/indexes/1/1636D8B1D7916DEA/ mwnid(home=/home/mailstore/%U$)=/home/mailstore/1636D8B1D7916DEA Apr 8 14:18:06 lxmhs23 deliver(username(a)xxx.de): maildir: data=/home/mailstore/1636D8B1D7916DEA//Maildir:INDEX=/home/mailstore/indexes/1/1636D8B1D7916DEA/ So, it looks like there is an issue using the same LDAP attribute (xxxMailbox in this case) twice in variable expansion. Is this a known issue? Of course there are several viable workarounds (base mail location on home directory, use the second attribute), but this problem was pretty surprising. Bernhard

[Dovecot] Trying nonplaintext mech with LDAP password-hash
by dovecotlist＠encambio.com 09 Apr '09

09 Apr '09

Hello List, The only passdb block in /pfx/etc/dovecot/dovecot.conf is: passdb ldap { args = /pfx/etc/dovecot/dovecot-ldap.conf } In /pfx/etc/dovecot/dovecot-ldap.conf: auth_bind = no dn = cn=mymgr,dc=host,dc=tld dnpass = ******** default_pass_scheme = LDAP-MD5 In /pfx/etc/openldap/slapd.conf: password-hash {MD5} If I try: $ /pfx/bin/ldapsearch <...> \ | grep '^userPassword' \ | sed -e 's;.*:: $.*$$;\1;' \ | mimencode -u ...I get the correct password (MD5 hashed.) According to wiki.dovecot.org/AuthDatabase/LDAP/PasswordLookups this should work, and indeed when starting dovecot it does not complain about: 'CRAM-MD5 mechanism can't be supported with given passdbs' Instead it starts right up, but when a thunderbird client connects and tries authenticating with CRAM-MD5 it fails. In the wiki page 'PasswordLookups' it mentions: Supports non-plaintext authentication mechanisms (if returning plaintext/properly hashed passwords). I've already verified that this works correctly with plaintext (CLEARTEXT in slapd.conf), but I really want to store the passwords in LDAP using some hash. Why doesn't LDAP-MD5 work as advertised? What did the author mean by 'properly hashed passwords'? Thanks. -- Eduard

[Dovecot] Dovecot 1.1.11 failing to accept SSL/TLS connections
by Mike Brudenell 08 Apr '09

08 Apr '09

Greetings - We are running Dovecot 1.1.11 on our servers and have been gradually migrating people off our old (UW-based) systems onto the new (Dovecot-based) ones. As a result the new systems are seeing more connections from more people. We have started seeing problems reported by users of our webmail service that they are getting an error indicating the webmail software (Prayer) has failed to establish an IMAP connection using TLS to Dovecot. Investigations show it is not just the webmail service that is affected but all mail clients: it's just other clients retry the connection, whereas Prayer fails the login and shows the error message: TLS/SSL failure for username.imap.york.ac.uk: SSL negotiation failed It seems to be related to one of Dovecot's imap-login processes getting a lot of file descriptors in use. We initially spawn off 10 imap-login processes and have each handling 256 connections. Full "dovecot -n" at the end of the message, but the relevant settings here are: login_process_size = 64 login_process_per_connection = no login_processes_count = 10 login_max_processes_count = 128 login_max_connections = 256 We have grown to suspect it is to do with one of the imap-login processes having a large number of files open. Killing the process seems to get rid of the problem. For example currently we have 11 imap-login processes running, one of which has 518 open files -- process 12436 in the list below. I suspect that, as in previous times we've encountered the problem, killing this process will alleviate the problem. (I'll be doing this later on this evening.) It is slightly odd that the imap-login processes have a very skewed distribution of open files, almost as if the algorithm for allocating connections to a process favours some over others. For example the current counts of open files are: Pid = Open files count 12430 = 42 26818 = 237 12431 = 90 12433 = 12 12438 = 304 12437 = 106 12435 = 190 12432 = 14 12436 = 518 12434 = 32 12429 = 12 Process 12436 was one of the 10 imap-login processes initially created back on March 3rd. (Process 26818 was the additional imap-login process spawned a little later on March 4th.) I don't believe the problem lies with the available file descriptors on the system: in the script which starts Dovecot I do date >/var/run/dovecot-limits ulimit -Sa >>/var/run/dovecot-limits echo "----------" >>/var/run/dovecot-limits ulimit -Ha >>/var/run/dovecot-limits ulimit -Sn 10128 echo "==========" >>/var/run/dovecot-limits ulimit -Sa >>/var/run/dovecot-limits echo "----------" >>/var/run/dovecot-limits ulimit -Ha >>/var/run/dovecot-limits $DOVECOT >>/var/run/dovecot-limits 2>&1 (The magic 10128 number came from Dovecot 1.1.11 itself, complaining that the number I had originally was too low.) Likewise the output of the pfiles command on process 12436 (which is the one I believe to be problematic) indicates its limit still has some available -- I'm guessing Dovecot has reduced the limit down to 533 from the 10128 set in the startup script: Current rlimit: 533 file descriptors We originally saw this problem with Dovecot 1.0.3 which we were running up until a couple of weeks ago. From there I upgraded first to 1.0.15 and then to 1.1.11. I'd hoped that upgrading would fix the problem: I see it has been mentioned before on the list, but not for a year or two. Can anyone give any help, please?

[Dovecot] Prohibit removing INBOX
by floss＠pbartels.info 08 Apr '09

08 Apr '09

Hello list, I'm using dovecot 1.1.11 and I'm going to prohibit users to remove their INBOX and some other directories in the mailbox root. I used Access Control Lists (http://wiki.dovecot.org/ACL) to do this: protocol imap { mail_plugins = acl } plugin { # With global ACLs in /etc/dovecot/acls/ directory: acl = vfile:/etc/dovecot/acls } /etc/dovecot/acls/.DEFAULT: owner lrwstie /etc/dovecot/acls/INBOX/.DEFAULT owner lrwstiekxa Actually - its not possible to create/remove directories under the mailbox root - its possible to create directories under INBOX - its NOT possible to remove directories under INBOX (This is my problem.) I tried symlinks like: /var/mail/.../INBOX/dovecot-acl -> /etc/dovecot/acls/INBOX/.DEFAULT /var/mail/.../dovecot-acl -> /etc/dovecot/acls/.DEFAULT But I think the symlink won't help because they doesn't change anything. And even with the symlinks its not possible to remove directories under IBOX. The documentation says: > If a mailbox has both global and per-mailbox ACL file, both of them > are read and the ACLs are merged. If there are any conflicts: > * v1.0 and v1.1: The per-mailbox ACL file overrides global ACL file. As far I can see it the documentation says nothing about merging ACLs of subdirs. But it seems the given behavior is not wanted by the dovecot design, because it seems it should be possible to override ACLs for subdirs, also give more permissions than the upper dirs. Is this a dovecot failure, do I miss something or is it really wanted by dovecot this way? My MUA (Evolution) says: > Cannot delete folder "INBOX/test". > Because "IMAP command failed: Permission denied". It unsubscribes the folder but it not able to remove it.

[Dovecot] Dovecot, LVS and the issues I have with it.
by neil 08 Apr '09

08 Apr '09

We run around 5 dovecot (debian etch 1.0.rc15) POP/IMAP 'nodes' using the LVS load balancer and an NFS based SAN. it works pretty well. I love the robustness of load balancing POP/IMAP. We do a reasonable amount of throughput through these especially at peak times pushing our SAN to around 1.5k IOP/s We currently have two issues with this setup. One of which is NFS index corruption issues we get due to NFS/dovecot locking. Basically the UUID list or a .index gets corrupt. This causes a full re-indexing of the mailbox / broken mailbox until i delete the indexes. In the UUID lists case the symptom tends to effect use who use POP rather than IMAP and insist on keeping messages on the server. Because it's corrupt it gets rebuilt one way or the other and the users email client proceeds to redownload the entire mailbox again until he remarks them to be saved. This tends to annoy the user a lot. After a bit of testing we do however expect this to be fixed by version 1.1. However if anyone has any comments on this I would certainly be interested. The other issue is a little tricky to describe or even log effectively. Occasionally a node basically receives more connections than it is able to handle. The connection count goes through the roof for that node. It will go up way beyond 150 dovecot authentication threads and 100 or so active POP/IMAP dovecot threads. The IO_wait/cpu and memory usage also tends to be spiking at this point. The server gets to the tipping point where it can no longer serve it's POP/IMAP requests fast enough compared to the number of connections it's getting. I'd be fine with this but this creates some less than desirable symptoms: 1. We obviously reach the auth thread cap eventually so any new auth requests basically get refused by the server. To the user this is a seen as an outlook/mail client re-auth pop-up request. This annoys them. Ideally if the server stops accepting auth requests it should fall off our load balancer until it can consistently accept them again. Since the LVS detects a node fail by whether the tcp port is still open this doesn't happen, since dovecot keeps the port open. This is obviously more an LVS issue and not for this mailing list I expect unless anyone has any config tweaking tips here? 2. Now here's my real gripe. Dovecot does not handle running out resources very gracefully at all in our setup. It does start killing threads after a while. I get multiple *"dovecot: child 17989 (login) killed with signal 9". *I'm not exactly sure what's going on here because after this all I can see is the machine totally out of memory and the kernel starts killing absolutely everything. All services are killed (including ssh etc..) and I plug a monitor into the server and find the last few lines of the console listing init and other rather important things having just been killed. At this point it is a case of power cycling the server and all is back to normal again. I imagine there's not a huge amount of people using dovecot in this way. But anyone got any recommendations here? I really like using dovecot in this setup it handles it pretty well and the redundancy and functionality options it provides have been invaluable. Neil

[Dovecot] Global Sieve File
by James Butler 08 Apr '09

08 Apr '09

Is anyone here using a global Sieve file that handles messages for an entire server with many users? I understand and use local Sieve files, but I would like to learn more about how to set up Sieve to filter ALL incoming messages using a single file. I would love to read about how you managed to get it working. I'm running Fedora 10 with Postfix 2.5.5 and Dovecot 1.2.rc2. Thanks for any insight! James

[Dovecot] Compiling v1.3 on different OSes
by Timo Sirainen 08 Apr '09

08 Apr '09

I was hoping to finally get shared libdovecot.so and libdovecot-storage.so libraries for v1.3, so Sieve (and maybe others) could link against them. But I'm running into trouble getting it to compile in Solaris 10. Could you non-Linux users test if this compiles with you? http://dovecot.org/tmp/dovecot-1.3.UNSTABLE.tar.gz Or if anyone has ideas why this happens, I'd like to know: libtool: link: gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -Wstrict-aliasing=2 -I/home/cras/include -o .libs/rawlog rawlog.o ../lib-dovecot/.libs/libdovecot.so -lrt -lsocket -lsendfile -Wl,-rpath -Wl,/usr/local/lib/dovecot ../lib-dovecot/.libs/libdovecot.so: undefined reference to `dlerror(a)SUNW_1.22' ../lib-dovecot/.libs/libdovecot.so: undefined reference to `dlopen(a)SUNW_1.22' ../lib-dovecot/.libs/libdovecot.so: undefined reference to `dlsym(a)SUNW_1.22' ../lib-dovecot/.libs/libdovecot.so: undefined reference to `dlclose(a)SUNW_1.22' If I disable plugins (so dl*() functions aren't used) it compiles, so it's only those functions that are problematic. pvs -s /lib/libc.so lists the dl* functions under SUNW_1.22 so I'd think that should have worked..

[Dovecot] v1.3 plugin locations
by Timo Sirainen 07 Apr '09

07 Apr '09

It's getting more and more annoying to have separate plugin directories for lda, pop3 and imap. Currently all the plugins are installed into $lib/dovecot/ and then symlinked to the lda, pop3, imap directories. The original reason was that v0.99 just loaded everything in those directories since there was no mail_plugins setting. But then there are things like expire-tool and convert-tool (and the upcoming doveadm) that don't load plugins at all, even though they probably should. Adding just more directories to them seems to be pointless. Also SQL plugins are shared by dovecot-auth and dict and those would need symlinking.. And in future you might want to load SQL plugins to e.g. imap process. So, I was planning on just putting everything into $lib/dovecot/. expire-tool etc. would use mail_plugins setting that wasn't inside protocol {}. So for example: mail_plugins = quota protocol lda { mail_plugins = quota sieve } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { # defaults to mail_plugins=quota above, no need to set it explicitly } That leaves auth and dict.. I was considering adding new auth_plugins and dict_plugins settings, but that might make it more difficult to start using distro-compiled Dovecot where sql, ldap, etc. are in plugins. So perhaps the auth/ and dict/ directories can stay and contain symlinks. But the $lib/dovecot/sql/ directory could go away and the sql plugins be stored just in $lib/dovecot/ among everything else. Any thoughts?

[Dovecot] Compile and configure Solr plugin
by Rui Carneiro 07 Apr '09

07 Apr '09

Hi all, I'm having some kind of troubles on Solr's integration. I configured Dovecot with the Solr argument (--with-solr) and everything proceeded just fine. But, when I started Dovecot I got this error: Plugin fts_solr not found from directory /usr/lib64/dovecot/modules/imap Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot/dovecot.conf In fact, there is no Solr plugin in that directory. So I tried to make a symbolic link from where the compiled Solr plugin was to this directory: ln -s /usr/local/lib/dovecot/lib21_fts_solr_plugin.so And now I have the following error: dlopen(/usr/lib64/dovecot/modules/imap/lib21_fts_solr_plugin.so) failed: /usr/lib64/dovecot/modules/imap/lib21_fts_solr_plugin.so: undefined symbol: mailbox_get_virtual_box_patterns Couldn't load required plugins Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot/dovecot.conf I'm missing some steps in this installation for sure, do anyone have any clue? Thanks, Rui Carneiro

[Dovecot] Modified websieve for use with dovecot
by Wolfgang.Friebel＠desy.de 07 Apr '09

07 Apr '09

In order to let users construct a sieve filter using a GUI I have taken websieve.pl from Alain Turbide (for use with Cyrus) and modified it to work with dovecot. In order to get it working quickly I have removed all the code I did not need (e.g. ldap support, password authentication) and coded Kerberos5 auth (via GSSAPI or SASL) in. I understand that this makes the work mostly useless to others. As however the dovecot adaptations were done by removing internally used perl packages by ones on CPAN such as Mail::IMAPClient and Net::Managesieve that part of the code should be of a broader interest. If someone is interested to have a look or even wants to help make it again a more universal tool I have put the code on ftp://ftp-zeuthen.desy.de/pub/unix/mail/websieve.pl Current status: I have tested the creation and modification of sieve rules, inspecting and setting ACL's (dovecot 1.2), displaying quota and creating folders. All the other code (e.g. the part that deals with an administrative user) is untested and probably not compatible yet with the new perl modules used. -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

[Dovecot] Script to install dovecot 1.2 plus Managerootsieve to CentOS5.2
by Bruce A. Mallett 07 Apr '09

07 Apr '09

I have no idea if this is of interest to anyone but it might save you some work .. I created a script that will install Dovecot 1.2-rc2 (currently) to a CentOS5.2 installation complete with Stephan Bosch's Managesieve, postfix, virtual users, LDAP, and LDAP personal address books. Oh right! .. and Squirrelmail plus various plugins (change LDAP password, LDIF import, Avelsieve). Also self-signed certificates are created from data supplied in a configuration file. I've stuck the required files here: http://www.nightstorm.com/~bam/CentOS5.2/ I did an install to a 32 bit CentOS so it has worked at least once on that architecture. It *should* work on a 64 bit as well (I provide the RPM) but I've not personally tested it. I am by no means an expert on any of this stuff (particularly the security aspects), so I'd certainly welcome any suggestions for ways to improve on the installation, the script, life, the universe, ... ;-) - Bruce

[Dovecot] v1.2: can't access other users shared INBOX

Why is it listed with "\Noselect"? 2) "user/A(a)example.com/INBOX" does not exist, so the error message is correct, but why does it appear in the listing in the first place? cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] Implementation of editheaders in dovecot
by Konstantin Lepa 06 Apr '09

06 Apr '09

Hello. I wrote the hook function for deliver. I want to add support of editheaders in the plug-in for dovecot. For this purpose I wrote the function rarules_get_stream. Remover of headrs works properly, but adding does not work. I took Timo Sirainen's advice from http://markmail.org/message/skb6arnll5gaopdr . Do I use a correct way of creation of a message? I give backtrace and a part of my code.

[Dovecot] is it possible to recover files from a dovecot.inboxe.cache file?
by Alfred Nutile 06 Apr '09

06 Apr '09

I found this file in the mail boz and noticed it had 20 emails in it (though you can only read really the header the body is cryptic cause it is a bin file?) Just not sure if I can and how to use this to restore the lost emails in that inbox. Thanks

[Dovecot] Segfault in Sieve 1.2
by Bernhard Schmidt 06 Apr '09

06 Apr '09

Hello, two days ago I've upgraded to 1.2rc2 and the new sieve implementation (version 0.1.4). Today I got the first mail that got stuck in the postfix queue because deliver was dying with a segfault. The mail is spam, thus I don't have any issues sharing it: http://users.birkenwald.de/~berni/temp/deliver-segfault.mail It happens with this small sieve script (my normal one is larger, but this is the part that triggers the segfault): http://users.birkenwald.de/~berni/temp/deliver-segfault.sieve Note that I've been running this script unaltered for months, first with Dovecot 1.1 and CMUSieve and now with various versions of Dovecot 1.2 and the new sieve implementation for about three weeks, this is the first mail that got stuck. I got a coredump, but without debugging symbols it doesn't tell that much. If you can't reproduce it I'll compile it with debugging symbols and try again.

[Dovecot] THREAD X-REFERENCES2 index bug?
by Nathan Kinkade 04 Apr '09

04 Apr '09

Hi all, $ sudo dovecot --version 1.2.beta3 I just started using Dovecot a few weeks ago, and my client is also using the X-REFERENCES2 thread algorithm. The client is misbehaving when trying to list messages in my INBOX, but only when a threaded message exists. I have tracked it down to the thread index that Dovecot is returning, but the problem is only extant when using the X-REFERENCES2 thread algorithm. Here is a snippet of transcript from imap client that comes with Dovecot: $ export MAIL=maildir:~/Maildir:INBOX=~/Maildir/INBOX $ /usr/lib/dovecot/imap <snip> 1 SELECT "INBOX" <snip> 2 THREAD X-REFERENCES2 UTF-8 ALL * THREAD (0)(2)(1 3)(4) 2 OK Thread completed. There are, in fact, only 4 messages in my INBOX, and the reference to (0) seems spurious. When I do the same test, but passing REFERENCES instead of X-REFERENCES2 Dovecot returns an index which I believe to be correct: <snip> 2 THREAD REFERENCES UTF-8 ALL * THREAD (1 3)(2)(4) 2 OK Thread completed. <snip> Is this the normal and expected behavior of X-REFERENCES2 that the client just needs to take into account, or is the reference to thread index (0) an error? Thanks! Nathan

http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc1.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc1.tar.gz.sig I think it's time to get v1.2.0 out soon. Shared mailbox code is beginning to look like it's working and other features should work fine also. I don't really see any reasons to delay it, so please start testing and let's get the last bugs found and fixed quickly. I'm also going to start v1.3 branch soon with configuration rewrite and multi-dbox support. Changes since beta4: * Renamed THREAD X-REFERENCES2 to THREAD REFS (from INTHREAD draft) + When a process is killed, show the signal code and the sending process's pid and uid. + quota-fs: Added support for NFS group quota. - Several fixes to shared mailboxes and ACLs - Removed umask setting. We're nowadays creating practically all files with proper umasks. - acl: Dropped default ACL cache timeout from 5 minutes to 30 seconds. - fts-solr fixes - virtual mailbox fixes - Write to main index file less often.

[Dovecot] Missing mail_max_userip_connections setting
by Thomas M Goerger 03 Apr '09

03 Apr '09

Hi, I'm having a problem with a webmail client trying to open multiple IMAP connections with dovecot, and hitting a cap. I see from the error logs from this program that it's hitting the mail_max_userip_connections cap, but I'm not seeing this value as defined in the dovecot.conf file. Would this automatically get set to a certain value by default if it's not present?

[Dovecot] Maildir files with mtime in the future
by Holger Weiss 03 Apr '09

03 Apr '09

If Maildir storage is used, the mtime of a given Maildir file is set to the message's INTERNALDATE. Now, when a client APPENDs a message to an IMAP mailbox, the client may optionally specify the INTERNALDATE: | If a date-time is specified, the internal date SHOULD be set in the | resulting message; otherwise, the internal date of the resulting | message is set to the current date and time by default. [ ftp://ftp.fu-berlin.de/doc/rfc/rfc3501.txt (6.3.11. APPEND Command) ] However, if the client does so, Dovecot will set the mtime of the Maildir file in question to the date specified by the client even if it's in the future. Since files with an mtime in the future can cause all sorts of trouble (e.g., they might get backed up repeatedly by incremental backups), it would be nice if Dovecot would (optionally?) use the current time if the client specifies a time in the future. For example, we use the following patch: ---------- 8< ---------------------------------------- 8< ---------- diff --git a/src/imap/cmd-append.c b/src/imap/cmd-append.c index 0b22fd5..b7e42b9 100644 --- a/src/imap/cmd-append.c +++ b/src/imap/cmd-append.c @@ -319,6 +319,12 @@ static bool cmd_append_continue_parsing(struct client_command_context *cmd) return cmd_append_cancel(ctx, nonsync); } + if (internal_date != (time_t)-1 && internal_date > time(NULL)) { + /* the client specified a time in the future, set it to now. */ + internal_date = (time_t)-1; + timezone_offset = 0; + } + if (ctx->msg_size == 0) { /* no message data, abort */ client_send_tagline(cmd, "NO Can't save a zero byte message."); ---------- 8< ---------------------------------------- 8< ---------- Holger

Dear all, I am trying to setup Dovecot with GSSAPI support. For testing purposes gssapi is the only method allowed for login. As I cannot login to my mailbox, I'vo got two questions about the following log entries: dovecot: Info: auth-worker(default): passwd-file /dovecot/store/db/test-userdb: Read 3 users dovecot: Info: auth(default): new auth connection: pid=3915 dovecot: Info: auth(default): client in: AUTH 1 GSSAPI service=imap lip=131.169.*.* rip=131.169.*.* lport=143 rport=35779 dovecot: Info: auth(default): gssapi(?,131.169.40.218): Obtaining credentials for imap(a)my.host.name dovecot: Error: imap-login: Timeout waiting for handshake from auth server. my pid=3918, input bytes=0 1. I am puzzled about the credentials "imap(a)my.host.name" being obtained; shouldn't this be something like "imap/my.host.name(a)MY.REALM" ? 2. what does "Timeout waiting for handshake from auth server." mean? Who is trying to handshake with whom? Any ideas?

[Dovecot] Time moved backwards errors
by Bloke 03 Apr '09

03 Apr '09

Hello, I am experiencing a number of 'Time moved backwards errors' such as: Mar 27 11:38:20 host-78-129-239-60 dovecot: imap-login: Time just moved backwards by 729 seconds. This might cause a lot of problems, so I'll just kill myself now. http://wiki.dovecot.org/TimeMovedBackwards Mar 27 15:20:10 host-78-129-239-60 dovecot: Time just moved backwards by 4214 seconds. This might cause a lot of problems, so I'll just kill myself now. http://wiki.dovecot.org/TimeMovedBackwards Mar 29 11:08:59 host-78-129-239-60 dovecot: imap-login: Time just moved backwards by 4341 seconds. This might cause a lot of problems, so I'll just kill myself now. http://wiki.dovecot.org/TimeMovedBackwards on my Centos 5.2 openvz - based VPS I have raised the issue with my VPS provider, who are responding that 'the jury is still out' as to whether this is a system, or Dovecot problem. Reading the TimeMovedBackwards article on the Dovecot wiki, and the kernel mailing list thread referred to on it, it would seem quite apparent that this is caused by a failure of the gettimeofday() function to reliably return the correct value. If anyone has any advice as to how I could proceed to fix this (I currently have a watch on the Dovecot service which restarts it after any failures) or how I should best phrase this to get it resolved 'upstream' by the VPS provider, I would be very grateful. Thank you, Patrick Vale

[Dovecot] dbox benchmarks
by Timo Sirainen 03 Apr '09

03 Apr '09

http://hg.dovecot.org/dovecot-dbox-redesign/ Looks like multi-dbox scales pretty nicely. Even after 100k messages the peak saved msgs/sec is the same as the initial saved msgs/sec, even if the average slows down somewhat. I tested this by first deleting mailbox, then running "imaptest" for a second to get saving to start writing several fields to dovecot.index.cache file. Then ran imaptest for 60 seconds that did nothing but save messages using IMAP APPEND commands. The summary is that multi-dbox is almost 10x as fast as maildir when fsync is disabled and 2,5 faster with fsyncing: fsync_disable=yes: multi-dbox : ~1700 -> ~1500 msgs/sec, 90842 msgs/60 sec single-dbox: ~1700 -> ~1400 msgs/sec, 86149 msgs/60 sec maildir : ~330 -> ~110 msgs/sec, 9789 msgs/60 sec fsync_disable=no: multi-dbox : ~220 -> ~170 msgs/sec, 10113 msgs/60 sec maildir : ~100 -> ~70 msgs/sec, 4123 msgs/60 sec Also I just noticed that saving messages with two clients gets a peak of 2200 msgs/sec, most likely because two CPU cores can be used then. Hmm. I guess if there were no locking it should have reached 3400 msgs/sec, but it's better than no performance increase. And the raw data: multi-dbox, fsync_disable=yes imaptest clients=1 secs=1;imaptest clients=1 msgs=1000000 - logout=0 append=100,0 secs=60 Logi Sele Appe 100% 100% 100% 1 1 1759 1/ 1 0 0 1424 1/ 1 0 0 1734 1/ 1 ... 0 0 1701 1/ 1 0 0 1640 1/ 1 0 0 778 1/ 1 0 0 1305 1/ 1 0 0 1598 1/ 1 Totals: Logi Sele Appe 100% 100% 100% 1 1 90842 multi-dbox, fsync_disable=no imaptest clients=1 secs=1;imaptest clients=1 msgs=1000000 - logout=0 append=100,0 secs=60 Logi Sele Appe 100% 100% 100% 1 1 209 1/ 1 0 0 227 1/ 1 0 0 208 1/ 1 ... 0 0 203 1/ 1 0 0 145 1/ 1 0 0 156 1/ 1 0 0 180 1/ 1 0 0 162 1/ 1 Totals: Logi Sele Appe 100% 100% 100% 1 1 10113 maildir, fsync_disable=yes Logi Sele Appe 100% 100% 100% 1 1 331 1/ 1 0 0 311 1/ 1 0 0 288 1/ 1 ... 0 0 96 1/ 1 0 0 119 1/ 1 0 0 111 1/ 1 Totals: Logi Sele Appe 100% 100% 100% 1 1 9789 maildir, fsync_disable=no Logi Sele Appe 100% 100% 100% 1 1 77 1/ 1 0 0 101 1/ 1 0 0 45 1/ 1 ... 0 0 52 1/ 1 0 0 67 1/ 1 0 0 89 1/ 1 Totals: Logi Sele Appe 100% 100% 100% 1 1 4123 single-dbox, fsync_disable=yes imaptest clients=1 secs=1;imaptest clients=1 msgs=1000000 - logout=0 append=100,0 secs=60 Logi Sele Appe 100% 100% 100% 1 1 1765 1/ 1 0 0 1715 1/ 1 0 0 1764 1/ 1 ... 0 0 1722 1/ 1 0 0 1679 1/ 1 0 0 1678 1/ 1 0 0 828 1/ 1 0 0 1467 1/ 1 0 0 1469 1/ 1 0 0 1149 1/ 1 0 0 1135 1/ 1 Totals: Logi Sele Appe 100% 100% 100% 1 1 86149

[Dovecot] An issue of I login my mail server from webmail client
by Alan Zheng 03 Apr '09

03 Apr '09

Dear all: I have a really strange issue, that is when I login my mail server from webmail client (I used SquirrelMail, by the way, I have modified squirrelmail's timeout value, that means not since squirrelmail timeout), I will got timeout issue when I login about 5PM ~ 10PM everyday (it works fine on other time, I also check my cron, that looks no problem), and during this time, I also cannot connect my 993 port with openssl like this: openssl s_client -connect myDomainName:993 But when I use mail client (such as outlook) to access dovecot, that works fine, and during 5PM ~ 10PM, my web site also works fine, and once I restart computer if I can not login during 5PM ~ 10PM from webmail client. that will work fine. can you try to help me? below is my configure of dovecot. *dovecot -n # 1.0.7: /etc/dovecot.conf log_path: /var/run/dovecot/maillog info_log_path: /var/run/dovecot/maillog protocols: imaps ssl_parameters_regenerate: 0 verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: maildir:~/Maildir mail_debug: yes auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix plugin: convert_mail: mbox:~/Mail:INBOX=/var/mail/%u* -- Best Regards Alan Zheng

[Dovecot] Dovecot ACLs
by dovecot＠corwyn.net 03 Apr '09

03 Apr '09

Running Dovecot 1.1.8 using Virtual users, multiple domains. My file structure is /var/spool/mail/<domain>/<user>/Maildir/ (cur, new,tmp,.Spam) What I'd like to do is add an ACL such that all users can read/delete/move mail that's in the spam folder, but not delete it. Am I going to have to create an entry for every single user, or is there a way to do it once, for all .Spam folders? I've read through http://wiki.dovecot.org/ACL and can't quite get this as the last step. Thanks rick Rick Steeves http://www.sinister.net "The journey is the destination"

Hello, I'am following the beginning tutorial on the Wiki, but actually, I can't even start the server correctly so far. The imap-login child dies immediately. What I can guess from the log is that it tries some unpermietted operations on some files but I can't find out which files are concerned. Google is not my friend at all either on this matter. How can I know which files are concerned ?

[Dovecot] Squat memory usage
by Ryan 02 Apr '09

02 Apr '09

I've been reading about using Squat with Dovecot on large mailboxes. I was wondering if some of the memory usage during searching and indexing could be reduced by using a berkeley db? I've used this in the past for something similar and in BTREE mode it was very fast for millions of keys. I havent had time to look at how squat is implemented, but I thought I'd throw it out there... -Ryan

Hi Timo, I'm playing with Dovecot v1.2.beta2 currently. When the dict process was started via deliver(?) and Dovecot is killed (kill $PID_OF_DOVECOT) after delivering only one message, it logs: Fatal: io_loop_handle_add: epoll_ctl(1, 10): Bad file descriptor If the dict process was not started or deliver has delivered more than one message, the error doesn't occur.

[Dovecot] quota-fs: get nfs GROUP quota (patch)
by fandorin＠rol.ru 02 Apr '09

Hi all. Unfortunately, the existing quota-fs does not know how to get GROUP quota with NFS storage. But there is a tool for Linux quota-tools (http://slackware.rol.ru/slackware/slackware-12.2/source/a/quota/) This patch is made on the basis quota-tools. The patch was successful alpha testing.

[Dovecot] File and group permissions for incoming mails
by Sascha Scandella 02 Apr '09

02 Apr '09

Hello I am using Dovecot 1.1.1 together with Postfix (and for some users Procmail for Spam Filtering). Until now I didn't have to use shared mailboxes. Now I want to use simple simlinking to grant other users of the same group access to my mails. The problem is that new incoming mails have always file permissions set to 0600. I have also a file called dovecot-shared (0660) in the Maildir folder. No success. Why doesn't this work? I also tried to use UMASK in the procmailrc. No success. Any help is appreciated! Best regards Sascha

[Dovecot] dbox - how to awaken the monster
by Odhiambo Washington 02 Apr '09

02 Apr '09

Hello people, Since the invention of this storage called dbox, I have never quite gotten round to understanding it, nor getting to use it. It seems so strange to me and I must ask a few stupid questions about it. I use the MTA to deliver mail to Maildir, either in ~/Maildir or /some/path/%d/%n/Maildir. It has always beat me how dbox comes into play under such circumstances. From the wiki, I see the following: "dbox supports a quick migration from Maildir format" - now this leaves me hanging. How? Suppose I migrate from Maildir to dbox, what changes do I make to the MTA to understand that I use dbox? Ok, I use Exim as my MTA. I hope someone can explain to me what I need to do to Exim and what to do th Dovecot so that I can test this dbox thing. And suppose I want to transfer userA's mail to UserB, what do I do? With Maildir, I can simply do something like mv ~A/Maildir ~B/Maildir chown -R B ~b/Maildir Suppose I am using dbox, howdy? Thank you in advance. I know those sound dumb, but I simply haven't understood dbox. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ "The only time a woman really succeeds in changing a man is when he is a baby." - Natalie Wood

[Dovecot] Dovecot in OSCON 2009?
by Timo Sirainen 02 Apr '09

02 Apr '09

Hi, I'm thinking about attending OSCON 2009 with some other people from Mailtrust and having some kind of an informal Dovecot meeting nearby. We could for example talk about what Dovecot would need to work better in your system, like missing features or if some things are annoyingly difficult etc, or just general talking and socializing. If you're interested in joining, send me a mail (privately, unless you have something else to say besides "yes").

[Dovecot] Slightly OT : Maildir format (silly) questions
by Thomas Hummel 02 Apr '09

02 Apr '09

Hello, I was asking what was the motivation for not having the envelope From in the Maildir format, as defined in the qmail spec : "The message is delivered without an extra UUCP- style From_ line, without any >From quoting, and without an extra blank line at the end." which may sound silly since we lose an important piece of information. Same question about the motivation in Courrier (Maildir++) for emulating a hierarchy for subfolders (like in .folder.subfolder.subsubfolder) instead of (note : I know about layout=FS, I'm not talking about that) implementing a real filesystem hierarchy. I understand dovecot kept those for compatibility reasons but I'd like to know what was the authors of thoses specs thinking when deciding this.

[Dovecot] Informations in LDAP and Database
by Etienne MAYNIER 02 Apr '09

02 Apr '09

Hi everybody, I'm installing an application using LDAP and I want dovecot to use LDAP too. The problem is that they don't use the same schema (especially because we want per-user quotas). I think the best solution is to have the authentication by LDAP and others datas (like quotas) in a database. Is it possible with dovecot ? and How ? Thanks Etienne

[Dovecot] postfix + dovecot

[Dovecot] courier-dovecot-migrate.pl issue
by Louis-David Mitterrand 02 Apr '09

02 Apr '09

Hi, I'm testing migration from courier to courier-0.57.0 to dovecot-imap-1.1.12 on a debian/sid box. When running the migration script, non of the active users' "courierimapsubscribed" and "courierimapuiddb" files seem to be detected: ZENON:~# ./courier-dovecot-migrate.pl --to-dovecot --recursive /home Testing conversion to Dovecot format Finding maildirs under /home /home/XXXX/Maildir: No imap/pop3 uidlist files /home/XXXX/CB: No imap/pop3 uidlist files /home/XXXX/Maildir/subscriptions already exists, not overwritten /home/XXXX/Maildir: No imap/pop3 uidlist files /home/XXXX/Maildir: No imap/pop3 uidlist files /home/XXXX/Mail: No imap/pop3 uidlist files /home/XXXX/Maildir: No imap/pop3 uidlist files /home/XXXX/Maildir: No imap/pop3 uidlist files Total: 0 mailboxes / 0 users 0 mailboxes / 0 users 0 errors No actual conversion done, use --convert parameter (the /home/XXXX users are old, non-active users) However when trying the courier-dovecot-migrate-1.0.pl I get plenty of mailbox matches, but since I am installing 1.1.12 it is useless to me. Dis I miss something? Thanks, -- http://www.critikart.net

[Dovecot] ampersand in local-part

I have a new email server (postfix/dovecot/mysql) with accounts migrated from another server (different platform) and email addresses with ampersands like "r&d(a)domain.com" that worked on my old email server are not working now.

[Dovecot] dbox with non-dovecot LDA
by Justin Krejci 01 Apr '09

01 Apr '09

Aside from the code is there any documentation on using dbox with a non-Dovecot LDA? We have our own MTA and currently use Dovecot with Maildir only for message retrieval and just have our MTA write the message files to our own directory structure (Dovecot per user mailbox locations stored in mysql) but I am interested in looking at moving to dbox if it is better for performance and other things like static filenames. One thing we'd like to do is not use the Dovecot LDA so as to control the entire inbound email delivery process all the way to verifying the actual message is 100% written to disk. Certainly we can use the Dovecot LDA if it came to it but we'd like to retain control over this entire process if possible.

[Dovecot] Virtual user folder configuration
by Daniel L. Miller 31 Mar '09

31 Mar '09

Since I'm going to make a change to my folder structure, what would be recommended so I can avoid the need in the future? All my mail users are virtual - they have no existence in /etc/passwd, nor do they have folders under /home. At this time, all mail is being delivered to maildir:/var/mail/%d/%n - and the home is the same (which is becoming more of a problem). As I see it, I have the choices of: 1. Place mail underneath home, as in /var/mail/%d/%n/mailbox Probably the simplest, but adds a level to the folder hierarchy. Does that matter in any way? 2. Place home underneath mail, as in /var/mail/%d/%n/home (unless THAT poses a problem as well, with a non-mail folder visible to the mail system) Leaves mail alone - but means the home folder is visible from within the mail system. 3. Relocate home totally outside mail, as in /var/mail/home/%d/%n Would provide isolation - but more difficulty in administration, particularly adding/deleting users. Any suggestions? -- Daniel

[Dovecot] CMUSieve with virtual users
by Guillaume HILT 31 Mar '09

31 Mar '09

Hi, I'm using dovecot 1.1.7 on Gentoo with Postfix and PostfixAdmin to manage my virtual users. I'm trying to use sieve (which has been compiled with Dovecot) but it doesn't work. I added cmusieve in the lda protocol : mail_plugins = cmusieve mail_plugin_dir = /usr/lib/dovecot/lda My maildir scheme is : /home/vmail/%d/%n/.maildir The sieve file is in /home/vmail/%d/%n/.dovecot.sieve (i'm using the sieve variable in the plugin section). I also tried in /home/vmail/%d/%n/.maildir/.dovecot.sieve. Then I tried in /var/sieve-scripts/%u.sieve. None of these solutions worked :x I enabled all the debug options in dovecot, and i can't see anything about sieve in my logs. I'm using the same configuration without virtual users on another server and it's working fine. I'm out of ideas. Could someone has managed to use sieve scripts with virtual users ? Thanks :) Guillaume

[Dovecot] Sieve Rule for Folders
by Gerhard Wiesinger 31 Mar '09

31 Mar '09

Hello! Is it possible with sieve to do the following: When a new message is added to a folder (e.g. dovecot folder and not INBOX) then an action like forwarding it per E-Mail should be triggered. Is this possible? If yes, how does the sieve script look like? If possible, can a shell script also be triggered as action? Thanx. Ciao, Gerhard -- http://www.wiesinger.com/

[Dovecot] Empty To: Header and message_address_parse
by Wolfgang.Friebel＠desy.de 31 Mar '09

31 Mar '09

Using dovecot 1.2beta (but earlier versions should behave similarly) we have a problem in conjunction with empty To: headers and the RT request tracker. RT sends mail out using Bcc: and no To: header at all. To make some mailers happy one can configure to send a dummy To: header, which we do. Our To header looks like: To: "AdminCc of rt Ticket #123456":; The message_address_parse function called with the TRUE flag (triggers add_fixed_address) in dovecot changes that to To: AdminCc of rt Ticket #123456: MISSING_MAILBOX@MISSING_DOMAIN ; and then at least alpine does use that invalid address as Cc: address when replying. If the mail is stored in a local folder, i.e. does not get fetched via IMAP then the To: line is displayed as is and a reply does not result in an errorneous Cc: This behaviour is at least inconsistent from a user point of view. Is there some advice other than change the RT mail header generation? (other mailers seem to copy the To: line unaltered which results in an invalid address as well, therefore I admit that the real problem is with RT) -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

[Dovecot] Convert from maildir to dbox
by Daniel L. Miller 31 Mar '09

31 Mar '09

Ok...I made the leap. Compiled a copy of 1.2b4 (very pleasant compile BTW - almost no warnings, nice code Timo!)...tweaked a config...had a few false starts... 1.2b4 seems to working quite nicely. Now...for my next magical trick... I would like to migrate from maildir to dbox. I've tried using the convert plugin, but it kept failing during the conversion. I should mention my paths: home (old & new) = /var/mail/%d/%n old mail = maildir:/var/mail/%d/%n new mail = dbox:/var/mail/%d/%n/dbox Note that "home" was defined as the same path as "mail" in my old config - I'm looking to fix that as well during the migration. I found entries in my mail log after the convert execution similar to: Mar 30 19:00:52 bubba dovecot: IMAP(sfox(a)amfes.com): rename(/var/mail/amfes.com/sfox/.dovecot.convert.lock/cur, /var/mail/amfes.com/sfox/dbox/mailboxes/dovecot/convert/lock/dbox-Mails) failed: Not a directory Mar 30 19:01:41 bubba dovecot: IMAP(sfox(a)amfes.com): Mailbox conversion failed for mailbox dovecot.convert.lock Now that I'm staring at that line...I'm wondering if that "home=mail" configuration is part of the problem. I currently have about a dozen users on this box - but with very large mailboxes (I still have archived mailing lists in mine!). If there's a few manual steps I need to perform to "condition" this setup prior to conversion please advise. Should I manually shift the mailboxes into a "/var/mail/%d/%n/maildir" folder? -- Daniel

[Dovecot] MAILBOXDIR question
by Stewart Dean 31 Mar '09

31 Mar '09

I'm unclear about where and how this is to be used. I gather it is to be a new standard, but I didn't seem to find anything about it in the Dovecot Wiki Mail Location page. There are some words about it in the 1.1.12/3 release notes, but perhaps I'm thick, but they're meta-ambiguous to me. Is it meant to be used like this: mail_location = mbox:MAILBOXDIR=~/mail:INBOX=/var/mail/%u instead of the current mail_location = mbox:~/mail:INBOX=/var/mail/%u ??? Sorry to be so dense. -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors. Now it's like an apartment in Bed-Stuy: you need three heavy duty pick-proof locks, one of those braces that goes from the lock to the floor, and bars on the windows.... ==== Stewart Dean, Unix System Admin, Bard College, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Panic: Trying to allocate 2147483648 bytes
by David Halik 30 Mar '09

30 Mar '09

Hi all, I recently upgraded from courier to dovecot 1.1.12 on a Solaris 9 system with about 100 users. We have been testing dovecot for sometime in a mixed Linux/Solaris environment and are aware of the index endianess issue with multiple archs. To solve this, we run with INDEX=MEMORY (as seen in the docs) so that only Linux clients have anything to do with the indexes. We generally have much more of them anyways. So far everything is working smoothly, but when someone does a search through directory with a large number of emails, dovecot dies and prints the following message: [ID 107833 mail.crit] Panic: Trying to allocate 2147483648 bytes I googled around and saw this same issue elsewhere, with NFS indexes usually being the problem. However, we have indexes turned off, so I don't understand why the same problem is still happening. Just to be sure, I ran with: mmap_disable = yes dotlock_use_excl = no mail_nfs_storage = yes But there has been no change, I can still reproduce it at will. Setting mail_nfs_index = yes caused my connections to stop working, so that didn't help either. Besides, I wouldn't think that would be the answer considering we set INDEX=MEMORY. This thread also seems to be related, but we're definitely running with this code in 1.1.12, yet it still happens: http://dovecot.org/list/dovecot/2008-September/033615.html I grabbed a backtrace if it is helpful: http://pastebin.com/f5f3d282c Also, here is dovecot -n: # 1.1.12: /usr/local/etc/dovecot.conf # OS: SunOS 5.9 sun4u protocols: imap imaps pop3 pop3s ssl_cert_file: /usr/local/ssl/certs/nbcs.key+crt.pem ssl_key_file: /usr/local/ssl/certs/nbcs.key+crt.pem 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 login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no mail_location: maildir:~/Maildir:INDEX=MEMORY mmap_disable: yes mail_nfs_storage: 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 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): UID%u-%v namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes auth default: passdb: driver: pam args: * userdb: driver: passwd plugin: quota: fs Any help would be appreciated!

[Dovecot] Upgrade from 1.0 to 1.1, plus migration from Maildir to dbox
by Daniel L. Miller 30 Mar '09

30 Mar '09

Ok - I gave up on trying to get CIFS to work - there's obviously stuff going on I don't understand. So - instead of trying to get a virtual server to work, I next tried a chroot. That worked...but imapsync error'ed out trying to handle one of my large mailboxes. I was trying to setup a "new" server, migrate all my mail over, verify everything worked - maybe even leave the virtual server operating for a while. But the fates are consipiring against me. So - time to make the leap. I want to upgrade a live version 1.0 server to version 1.1 (from Ubuntu repositories, using version 1.0.10 to 1.1.4). What special steps do I need to take to have this go smoothly? At least I have some semi-tested configs for 1.1 that I can use. Do I just stop the server, upgrade, upgrade the configs, start - and pray? Or is there another step? Also, my legacy installation was using maildir - I'd like to try shifting to dbox. Do I just need to change the prefix on mail_location and the conversion will magically happen? -- Daniel

[Dovecot] dovecot: auth(default): ldap(...): Authenticated user not found
by Stas SUSHKOV 29 Mar '09

29 Mar '09

Hi, I'm trying to set up dovecot together with postfix and experience some problems. Here's in details what I have and what I want to get. I have a ldap server on localhost, a working setup of dovecot to serve sasl, imap using ldap, a working setup of Postfix for (s)smtp (I can authenticate which uses dovecot's sasl). What i wan't to get is a completely working email server for ldap users with their email forwardings (so far they have only 1 forwarding). The porblem I stuck on is the following: when sending mail through (s)smtp, after passing authentication, I get my email dropped. And I see this in logs: http://ciorne.softwareliber.ro/index.php/view/raw/aaf3eb42 ***Authenticated user not found!!!*** My dovecot conf is this: http://ciorne.softwareliber.ro/index.php/view/raw/f8696531 And my dovecot-ldap is this: http://ciorne.softwareliber.ro/index.php/view/raw/698dc851 (I'm using prefetch) Can somebody point me where's my problem. *Any* advices are welcomed!!! Thank you in advance. P.S.: Environment is a vanilla installation of Ubuntu 8.04.02 with latest updates. -- () Campania Panglicii în ASCII /\ http://stas.nerd.ro/ascii/

Hi, I was wondering if I can make sendmail use dovecot's SASL implementation...maybe I should somehow compile it against dovecot's SASL ?

Hi, Is there a way for dovecot to use a pool of sql (mysql) servers and load balance queries between these? Also fallback to next available sql server if connection to previous one fails. Can dovecot do such things currently? (If not this is feature request). -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

[Dovecot] Making changes to dovecot log levels
by Thomas M Goerger 27 Mar '09

27 Mar '09

Hi Timo, Not sure if you saw this yet, or if you're still working on a response. Awhile back I'd written about making changes to some of the log levels that dovecot writes to to stop the process from writing these to monitor. I wanted to run a few changes by you for this, just to make sure these won't cause problems somewhere else. And to send this to the list, in case anyone else wants to make similar changes in the future. In the file src/lib-index/mail-index.c: duplicate the function mail_index_set_error to mail_index_set_warning and call this function in /src/lib-index/mail_cache.c instead int mail_index_set_error(struct mail_index *index, const char *fmt, ...) { va_list va; i_free(index->error); if (fmt == NULL) index->error = NULL; else { va_start(va, fmt); index->error = i_strdup_vprintf(fmt, va); va_end(va); i_error("%s", index->error); } return -1; } changing the line : i_error("%s", index->error); to i_warning("%s", index_error); and for the file src/lib-storage/index/mbox/mbox-sync.c changing this code if (rec == NULL && uid < sync_ctx->idx_next_uid) { /* this UID was already in index and it was expunged */ mbox_sync_set_critical(sync_ctx, "mbox sync: Expunged message reappeared in mailbox %s " "(UID %u < %u, seq=%u, idx_msgs=%u)", sync_ctx->mbox->path, uid, sync_ctx->idx_next_uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; } else if (rec != NULL && rec->uid != uid) { /* new UID in the middle of the mailbox - shouldn't happen */ mbox_sync_set_critical(sync_ctx, "mbox sync: UID inserted in the middle of mailbox %s " "(%u > %u, seq=%u, idx_msgs=%u)",sync_ctx->mbox->path, rec->uid, uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; from mbox_sync_set_critical( etc... to mail_storage_clear_error(storage) i_warning("Error text"... mail_storage_set_internal_error(storage) to clear and set the storage pointer Hopefully that's all clear.

[Dovecot] outlook problem if TLS mailsettings are off

Dear List, I dont know if its a config problem or its an outlook 2007 issue. Behaviour: If I set /etc/dovecot/dovecot.conf: Following is valid with IMAP mailboxes only: disable_plaintext_auth = yes # outlook 2007 with TLS in/out enabled) can show index of mails and klick on mail does preview / doubleklick opens mail PERFECT AS INTENDED disable_plaintext_auth = no # outlook 2007 with TLS/SSL OFF can show index of mails, but (double)-/klick on mail gives me "sandwatch"-mouspointer and I've to restart outlook again (and enable TLS again to get it work again) with POP3 mailbox both variants are working smoothly.

Hi all, I have a dovecot installation which very suddenly decided to slow to a crawl yesterday after being totally fine for months. IMAP is fine, but POP3 is very painful to use, and frequently times out. here's my config: # 1.0.7: /etc/dovecot.conf log_path: /var/log/dovecot_errors info_log_path: /var/log/dovecot_informational ssl_ca_file: /etc/postfix/ssl/cacert.pem ssl_cert_file: /etc/postfix/ssl/postfix.webworks.ie.crt ssl_key_file: /etc/postfix/ssl/postfix.webworks.ie.key login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_process_per_connection: no login_processes_count: 6 first_valid_uid: 89 mail_location: maildir:/home/vmail/%d/%n mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: passdb: driver: pam passdb: driver: sql args: /etc/dovecot-mysql.conf userdb: driver: sql args: /etc/dovecot-mysql.conf I tried an strace as suggested by some other people. didn't know exactly what to attach it to, so did a "ps aux" (Centos 5.2, btw) and chose the first "pop3" process: [root@postfix cur]# strace -p 1697 Process 1697 attached - interrupt to quit gettimeofday({1238146840, 724484}, {0, 0}) = 0 gettimeofday({1238146840, 724542}, NULL) = 0 poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=2, events=POLLERR|POLLHUP|POLLNVAL}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=1, events=POLLOUT|POLLERR|POLLHUP|POLLNVAL}], 4, 3123) = 0 gettimeofday({1238146843, 847540}, {0, 0}) = 0 gettimeofday({1238146843, 847590}, NULL) = 0 poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=2, events=POLLERR|POLLHUP|POLLNVAL}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=1, events=POLLOUT|POLLERR|POLLHUP|POLLNVAL, revents=POLLOUT}], 4, 10000) = 1 gettimeofday({1238146847, 807077}, {0, 0}) = 0 write(1, "6DEDK02J5VXFQtloRQ/JPgdcCrSmSRXj"..., 2171) = 2171 setsockopt(1, SOL_TCP, TCP_CORK, [1], 4) = 0 pread64(9, "7P8JZloV9g/oYWdnm\nnZ9f+xzkO3fVXr"..., 4096, 102400) = 4096 write(1, "\r\nLhQoxZy+rq1TZXl2ZtrKrZH15dE2PK"..., 4134) = 3669 write(1, "uv69IdP6FDbO0lztPh2sA6Z/wBqIdP9Y"..., 465) = -1 EAGAIN (Resource temporarily unavailable) setsockopt(1, SOL_TCP, TCP_CORK, [0], 4) = 0 gettimeofday({1238146847, 807691}, NULL) = 0 poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=2, events=POLLERR|POLLHUP|POLLNVAL}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=1, events=POLLOUT|POLLERR|POLLHUP|POLLNVAL}], 4, 6040) = 0 gettimeofday({1238146853, 847046}, {0, 0}) = 0 gettimeofday({1238146853, 847095}, NULL) = 0 poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=2, events=POLLERR|POLLHUP|POLLNVAL}, {fd=0, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=1, events=POLLOUT|POLLERR|POLLHUP|POLLNVAL, revents=POLLOUT}], 4, 10000) = 1 gettimeofday({1238146856, 546780}, {0, 0}) = 0 write(1, "uv69IdP6FDbO0lztPh2sA6Z/wBqIdP9Y"..., 465) = 465 setsockopt(1, SOL_TCP, TCP_CORK, [1], 4) = 0 pread64(9, "24\nekSIYgeKr5kpQwrk4iWMqC2+/uvwf"..., 4096, 106496) = 4096 write(1, "\r\nIHaoJDSPFqr4jw9SP8S2yLsWOt2RVx"..., 4134) = 4134 pread64(9, "DUJvKTRdVNxs3JTdRQYqD61EYbg22DLb"..., 4096, 110592) = 4096 write(1, "\r\nbDlx3+0LszvjOrD5+04T8PF39frFpQ"..., 4134) = 1241 write(1, "9Zc/wAr\r\nF1bI22U8dNTIKBc423KFJSO"..., 2893) = -1 EAGAIN (Resource temporarily unavailable) setsockopt(1, SOL_TCP, TCP_CORK, [0], 4) = 0 gettimeofday({1238146856, 547406}, NULL) = 0 poll( <unfinished ...> Process 1697 detached looking forward to you all saving my sanity! thanks, kae

[Dovecot] Preventing IMAP folder deletion?
by dovecot＠corwyn.net 27 Mar '09

27 Mar '09

Hi! I'm running postfix with dovecot using mysql for user accounts, with Outlook being used as the IMAP mail client. I'm using a mail delimiter ("+") and mail automatically goes to a Spam folder as part of spam filtering with amavisd and spam assassin. It's configured so that folders won't automatically create; if the folder isn't there mail delivers to the inbox (so that spam doesn't create extra folders). the problem I ran into today is that a user deleted the Spam folder. While recreating it isn't that hard, is there a way I can prevent them from being able to delete specific folders in IMAP? In squirrelmail I can create "system" folders that the user can't change or delete, but that's client based. Since I don't see that ability in Outlook, can I somehow configure dovecot so the user can't delete specified folders? Thanks Rick Rick Steeves http://www.sinister.net "The journey is the destination"

[Dovecot] Version 2.0 with multiple IP/TLS certificate support.
by Gordon Dickens 26 Mar '09

26 Mar '09

Hello, I sent this email earlier but for some reason it did not go through so I will try again! I am using Dovecot on several servers that require multiple domain SSL certificates. I like Dovecot very much because of its speed and stability. Currently, Dovecot does not support multiple SSL certificates directly although I have gotten around this problem with multiple Dovecot instances running multiple configuration files. However, I would prefer to have one configuration file that supports multiple domain certificates. My understanding is that Dovecot Version 2.0 will have this "multiple SSL certificate" feature. So, my question is, when is version 2.0 projected to be released? Many thanks! Gordon Dickens

[Dovecot] v1.2.beta4 released
by Timo Sirainen 26 Mar '09

26 Mar '09

http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta4.tar.gz http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta4.tar.gz.sig This release fixes a memory corruption bug related to MODSEQ handling in earlier v1.2 releases. Memory corruption means that it's a security bug and possibly exploitable. MODSEQ code is new in v1.2, so v1.1 and older releases are not affected. Other than that, there is an ESORT bugfix and other fixes that were added to v1.1 branch too.

[Dovecot] Missing TMP folder - Dovecot 1.2 Beta3
by Matt Rude 26 Mar '09

26 Mar '09

Recently after upgrading to 1.2 Beta3 from 1.1.13, I started to defer mail. After looking into it deeper, it looks like Dovecot/sieve now asks for a tmp folder in the imap (maildir) folder. Once I added the tmp folder as the logs indicants, the mail was processed normally. I have split my Inbox and imap store to different folder. Looking at what it's trying to do, it looks to me that dovecot/sieve expect the imap directory to be the Inbox. Is this a bug, or intended behaver? # Log output, when requeueing the message in postfix, with mail_debug on ######################################################################### Mar 24 12:02:50 samantha postfix/qmgr[6855]: EB4141237BD: from=<colleen(a)example.com>, size=493284, nrcpt=1 (queue active) Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Loading modules from directory: /usr/local/lib/dovecot/lda Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Module loaded: /usr/local/lib/dovecot/lda/lib10_quota_plugin.so Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Module loaded: /usr/local/lib/dovecot/lda/lib20_expire_plugin.so Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Module loaded: /usr/local/lib/dovecot/lda/lib90_cmusieve_plugin.so Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): auth input: maildir=example.com/jill@example.com/ Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): auth input: uid=1000 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): auth input: gid=1000 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): auth input: quota_rule=*:storage=524288 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Quota root: name=User quota backend=maildir args= Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Quota rule: root=User quota mailbox=* bytes=536870912 messages=0 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Quota rule: root=User quota mailbox=Trash bytes=53687091 (10%) messages=0 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Quota rule: root=User quota mailbox=Junk bytes=107374182 (20%) messages=0 Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): maildir: data=/var/spool/virtualmailboxes/example.com/jill@example.com/imap/:INBOX=/… Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): maildir++: root=/var/spool/virtualmailboxes/example.com/jill@example.com/imap, index=/var/spool/virtualmailboxes/Indexes/example.com/jill@example.com, control=, inbox=/var/spool/virtualmailboxes/example.com/jill@example.com Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): cmusieve: /var/spool/virtualmailboxes/example.com/jill(a)example.com/dovecot.sieve doesn't exist Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): cmusieve: Using sieve path: /var/spool/sieve/dovecot.sieve Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): cmusieve: Executing script /var/spool/sieve/dovecot.sievec Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): Namespace : Using permissions from /var/spool/virtualmailboxes/example.com/jill(a)example.com/imap: mode=0700 gid=-1 ****** Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): creat(/var/spool/virtualmailboxes/example.com/jill@example.com/imap/tmp/tem… failed: No such file or directory ****** Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): copy: i_stream_read() failed: No such file or directory Mar 24 12:02:50 samantha dovecot: deliver(jill(a)example.com): msgid=<85866319ca18bf9cd994e34fe806c4f5.squirrel(a)mail.mattrude.com>: save failed to INBOX: Internal error occurred.

[Dovecot] Dbox Upgrade Problem With MAILBOXDIR
by Alan Swanson 25 Mar '09

25 Mar '09

Hi. Trying to upgrade from Dovecot 1.1.11 to 1.1.13 but having a problem with imap process segfaulting. Backtrace is below.

[Dovecot] selection correct auth with multiple auth methods
by jm 25 Mar '09

25 Mar '09

How do you control which socket or authentication process dovecot's pop3 daemon chooses to use? I've got a user database with two flags one to allow pop3 access and the other to allow the use of auth smtp. There are two authentication instances configed, thus, auth default { .... passdb sql { args = /etc/dovecot-sql-postfix.conf } .... socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = group = } } auth postfix { ..... passdb sql { args = /etc/dovecot-sql-postfix.conf } .... socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } From the logs and testing pop3 is using the postfix authentication instance and not the default as expected. Does anyone out there know how control dovecot's pops daemon authentication choice? This infomation seems to be lacking in the documentation I can find. Jeff.

[Dovecot] Making changes to dovecot log levels
by Thomas M Goerger 24 Mar '09

24 Mar '09

Hi Timo, Awhile back I'd written about making changes to some of the log levels that dovecot writes to to stop the process from writing these to monitor. I wanted to run a few changes by you for this, just to make sure these won't cause problems somewhere else. And to send this to the list, in case anyone else wants to make similar changes in the future. In the file src/lib-index/mail-index.c: duplicate the function mail_index_set_error to mail_index_set_warning and call this function in /src/lib-index/mail_cache.c instead int mail_index_set_error(struct mail_index *index, const char *fmt, ...) { va_list va; i_free(index->error); if (fmt == NULL) index->error = NULL; else { va_start(va, fmt); index->error = i_strdup_vprintf(fmt, va); va_end(va); i_error("%s", index->error); } return -1; } changing the line : i_error("%s", index->error); to i_warning("%s", index_error); and for the file src/lib-storage/index/mbox/mbox-sync.c changing this code if (rec == NULL && uid < sync_ctx->idx_next_uid) { /* this UID was already in index and it was expunged */ mbox_sync_set_critical(sync_ctx, "mbox sync: Expunged message reappeared in mailbox %s " "(UID %u < %u, seq=%u, idx_msgs=%u)", sync_ctx->mbox->path, uid, sync_ctx->idx_next_uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; } else if (rec != NULL && rec->uid != uid) { /* new UID in the middle of the mailbox - shouldn't happen */ mbox_sync_set_critical(sync_ctx, "mbox sync: UID inserted in the middle of mailbox %s " "(%u > %u, seq=%u, idx_msgs=%u)",sync_ctx->mbox->path, rec->uid, uid, sync_ctx->seq, messages_count); ret = FALSE; rec = NULL; from mbox_sync_set_critical( etc... to mail_storage_clear_error(storage) i_warning("Error text"... mail_storage_set_internal_error(storage) to clear and set the storage pointer Hopefully that's all clear. If you have any questions, please let me know.

[Dovecot] Problem with dovecot + imap idle + qmail-local delivery
by Jochen Schug 24 Mar '09

24 Mar '09

Hi, I've recently switched from courier-imap to dovecot. Everything seemed to work fine, but after I while I noticed that dovecot is occasionaly causing problems with delivery of new incoming mails. System: Gentoo Linux, kernel 2.6.19, qmail 1.03, vpopmail 5.4.26 , dovecot 1.1.11, maildir, mail store on ext3. Symptoms: qmail is having trouble with the mail delivery. First I thought it had something to do with vpopmail or dovecot's quota support, but I tracked it down to qmail-local. I tried two different versions, one with Bill Shupp's maildir++ patch and one without. With the patch, I'm getting "User_over_quota._(#5.1.1)" errors. Mail is delivered once and sender is sent a notification about the exceeded quota. Without the patch, I get "Temporary_error_on_maildir_delivery._(#4.3.0)". Mail is delivered, but delivery is tried again and again. This only happens if a MUA is logged in to the mailbox and IMAP IDLE is being used. If the MUA is disconnected: fine. If dovecot is stopped: fine. I tried a couple of different things, all without success: - upgraded dovecot from 1.1.7 to 1.1.11 - compiled a new kernel with inotify support and recompiled dovecot - migrated mail store from reiserfs to ext3 - disabling quota support in dovecot - tried dovecot's various file locking mechanisms Right now I'm working around this by removing IDLE from the capabilities. This solves the problem, but leaves me with a less functional IMAP server. Any help is greatly appreciated.

[Dovecot] Staged migration from mbox to maildir
by Stewart Dean 24 Mar '09

24 Mar '09

So much changes in this migration that the ideal way to do it would be to begin with a few users or a department, then migrate the users affinity group by affinity group: first an institute or so, then the faculty, then the staff, then the students, moving to bigger and bigger groupings as the bugs work out of the migration and the move becomes more assured. We use sendmail and procmail. There's no problem there, as the ~./procmailrc can be changed to over-ride the mbox default until all groups are done and it become the default. The problem comes with IMAP. While dovecot can tell if a folder is mbox or maildir, it has to be pointed to the right place (by namespace definitions in the client, IIRC), and the default of putting the inbox under ~/mail is one I'd like to embrace for various reason...but given that that means moved inbox folders and *that* means either making a global change (there goes staged migration) OR changing the namespace definitions on each PC. I can get to the early few and change the namespaces definition, but there doesn't appear to any equivalent (enlighten me, if I'm missing something) to ~/.procmailrc for imap, so that I don't have to get on the client machine. Is this correct or am I (hopefully) wrong and there *is* a way to change things on the server that allows for staged migration? Oh, I would so like to be wrong!

[Dovecot] Released Sieve v0.1.4
by Stephan Bosch 23 Mar '09

23 Mar '09

Hello Dovecot users, Not much Sieve development was done in the last five weeks, but some important platform-dependent bugs were found and repaired. The main new feature is the addition of a custom Sieve language extension for debugging in the Sieve command line tools. Changelog Sieve v0.1.4: * Started work on the sieve-filter tool. With this command line tool it will be possible to (re-)apply Sieve filters on a mail folder. It is currently undocumented and far from functional. + Added a custom debug extension that provides the possibility to print debug messages from scripts executed by the Sieve tools. - Fixed issue with opening relative paths as a mail file. Bug reported by Ian P. Christian. - Fixed MAC OSX compile problem. Turns out the extern modifier was missing at multiple places. Bug reported by Edgar Fuss. - Fixed Solaris compile problem: removed unecessary and unportable linker flags that caused compile to fail. Bug reported by Andres Yacopino. The release is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.4.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.4.tar.gz.sig Have fun testing the new release and don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Single Instance Storage still on the roadmap?
by Charles Marcus 20 Mar '09

20 Mar '09

Hey Timo, I was curious where Single Instance Storage fits in on the roadmap, now that you are maybe settled in in your new digs... Is it still coming soon? Has it been pushed back by your new employers priorities? Its real high on mine, so if has been back-burnered, I'll need to start looking for alternatives... Thanks, -- Best regards, Charles

[Dovecot] update of current quota usage
by floss＠pBartels.info 20 Mar '09

20 Mar '09

Hello, I use Dovecot 1.1.11 and store the current quota usage in a Database. As far I can see it, the quota usage is updated each time dovecot performs an action on a mail. For example if a new mail is stored in the inbox, the current quota usage is increased. If a mail is deleted the quota usage is decreased. If there are still existing E-Mails in the inbox, before quota is turned on or if I perfom changes on the "mail storage" myself (for example purging trash or spam, or something) the current quota usage is NOT updated automatically by dovecot. For example I copy some mailboxes to my server, then the current quota for this mailboxes is still zero. Is it correct that dovecot can't do this for me? If yes, it seems I have to write my own (simple) update script and run it sometimes croned (because I don't really trust the actual quota implementation) and/or I have to update the current quota usage each time I perform actions myself. This "workaround" is easy by using a DB storage, but what about other implementations? Wouldn't it be nice if dovecot could do this or provide a tool for it? Thank you! Philipp

[Dovecot] ESORT broken in Dovecot 1.2

Looks like ESORT is broken (just compiled 1.2 from hg 10 minutes ago). Here is the command I'm using and the corresponding error message: C: 5 UID SORT RETURN (ALL COUNT) (ARRIVAL) US-ASCII UNSEEN S: 5 BAD Error in IMAP command UID: Invalid sort argument. The corresponding UID SORT command (without the RETURN syntax) works fine: 5 UID SORT (ARRIVAL) US-ASCII UNSEEN * SORT 5 OK Sort completed (0.000 secs). michael
