Maildir: ACLs/Unix perms and unable to see content of specific mailbox
by Olaf Marzocchi 10 Oct '15

10 Oct '15

Dear Dovecot users, hello. I will merge two issues I have into a single email because they may be related. I used dovecot on a OmniOS server since 2014 (currently OmniOS r151014) with the following configuration (it shows 2.2.18 because I recently updated dovecot, skipping only the PostgreSQL plugin): # 2.2.18: /etc/dovecot/dovecot.conf # OS: SunOS 5.11 i86pc zfs mail_location = maildir:/tank/home/%u/Maildir mail_privileged_group = mail namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = imap ssl = required ssl_cert = </etc/dovecot/certs/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = passwd } You can see that I set the Maildir folder inside the shared home folders of my server (it is only one user, anyway). It always worked perfectly, but one-two months ago I changed the permissions of my whole home folder, recursively, to add proper ACLs. I needed them because the clients started using illumos kernel SMB (relying on ACLs) instead of Netatalk/AFP (relying on Unix perms only). I didn't realise I applied the ACLs also to the Maildir folder. Dovecot worked for several weeks fine, I noticed the issue only yesterday when a mailbox (see below) appeared in Thunderbird completely empty even if the "cur" subfolder on the server still contains all the mails. Dovecot was throwing some errors like: dovecot: [ID 583609 mail.error] imap(olaf): Error: rename(/tank/home/olaf/Maildir/.&A6k- Mailing Lists.Log/dovecot.index.cache) failed: Permission denied (euid=501(olaf) egid=501(olaf) UNIX perms appear ok (ACL/MAC wrong?)) dovecot: [ID 583609 mail.error] imap(olaf): Error: rename(/tank/home/olaf/Maildir/.&A6k- Mailing Lists.Log/dovecot.index.tmp, /tank/home/olaf/Maildir/.&A6k- Mailing Lists.Log/dovecot.index) failed: Permission denied dovecot: [ID 583609 mail.error] imap(olaf): Error: unlink(/tank/home/olaf/Maildir/subscriptions.lock) failed: Permission denied dovecot: [ID 583609 mail.error] imap(olaf): Error: rename(/tank/home/olaf/Maildir/subscriptions.lock, /tank/home/olaf/Maildir/subscriptions) failed: Permission denied I will post here the current permissions of the folder containing Maildir, of the Maildir itself, of its contents, and of the folder that appears empty when browsed with a client (Thunderbird). /tank/home/olaf $ ls -lV .. drwx------+ 16 olaf olaf 17 Sep 19 01:52 olaf user:olaf:rwxpdDaARWcCos:fd-----:allow group:2147483648:rwxpdDaARWcCos:fd-----:allow everyone@:rwxpdDaARWcCos:fd-----:deny /tank/home/olaf $ ls -lV drwxrwx--- 348 olaf olaf 359 Sep 19 01:51 Maildir owner@:rwxp--aARWcCos:-------:allow group@:rwxp--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow /tank/home/olaf $ ls -lV Maildir/ drwxrwx--- 2 olaf olaf 2 Jan 30 2014 cur owner@:rwxp--aARWcCos:-------:allow group@:rwxp--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow -rwxrwx--- 1 olaf olaf 21 Jan 30 2014 dovecot-keywords owner@:rwxp--aARWcCos:-------:allow group@:rwxp--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow (ALL THE SAME PERMISSIONS FOR THE OTHER FILES EXCEPT...) -rwxrwx--- 1 olaf olaf 13735 Jan 24 2015 subscriptions owner@:rwxp--aARWcCos:-------:allow group@:rwxp--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow -rw-rw---- 1 olaf olaf 13709 Sep 19 01:51 subscriptions.lock owner@:rw-p--aARWcCos:-------:allow group@:rw-p--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow The folder that appears empty: /tank/home/olaf $ ls -lV Maildir/.Generiche/ total 513 drwxrwx--- 2 olaf olaf 949 Sep 18 01:42 cur owner@:rwxp--aARWcCos:-------:allow group@:rwxp--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow -rwxrwx--- 1 olaf olaf 46 May 18 2014 dovecot-keywords owner@:rwxp--aARWcCos:-------:allow group@:rwxp--a-R-c--s:-------:allow everyone@:------a-R-c--s:-------:allow (ALL THE SAME PERMISSIONS FOR THE OTHER FILES) I really hope you will have the time to help me because I already applied the permissions recursively and I removed the ACLs, almost as it was before my mistake. I specified "almost" because originally (I checked the backups) the Maildir folder had an ACL that gave access permissions also to the group "mail": drwxrwx---+349 olaf olaf 359 Feb 16 2014 Maildir group:mail:rwxpdDaARWcCos:fd-----:allow owner@:rwxpdDaARWcCos:fd----I:allow group@:rwxpdDaARWcCos:fd----I:allow everyone@:rwxpdDaARWcCos:fd----I:deny Yesterday I haven't replicated it because from the documentation I understood it was not necessary. My questions, in short: - what are the permissions I need to give to the Maildir folder? I understood from the documentation it's 700, with my user/group (the one of the user accessing the mail). What about ACLs? and what about group "mail"? - the (only!) subfolder which appears empty in Thunderbird, may it depend on the permissions? maybe due to them the index was not updated and UIDs don't match. If after applying the correct permissions I still cannot see its contents, is there a way to recover the mails? the files are all still there. Sorry for the long email, but after several tries yesterday I exhausted my ideas. Regards, Olaf

Double Dots
by Ken Mandelberg 09 Oct '15

09 Oct '15

I've noticed lately that Dovecot seems to be inserting an extra dot in some url's contained in html email. The most consistent example I see is in the newsletters from the Washington Post. For example, if I look at the raw email on the mail server I see text that starts <http://link.washingtonpost.com/click But if I look at what Thunderbird shows it starts http://link..washingtonpost.com/click/ I don't think its Thunderbird adding the dot, since K9 mail on my Android phone shows the same issue. It's only after the IMAP delivery that the extra dot appears. We are running dovecot 2.0.12 Incidentally, the newsletter is full of these link.washington post url's. For each article it appears 3 times, once on title, once on a "read full article" link, and one on a picture. Its only the one on title, that gets the extra dot after its been through dovecot. Furthermore, it only happens from the second article on. Any ideas?

Dovecot plugin and Push Mail
by Steffan Cline 08 Oct '15

08 Oct '15

I’m posting this here and will in a couple other places to see if anyone has any experience with this and knows what I can do. My setup is CentOS 6 with postfix, procmail and dovecot administered via Virtualmin. Postfix of course receives the email. Procmail uses it’s hooks to run the email through spam assassin and clamd. After than procmail hands it off to dovecot/deliver to drop it in the user’s mail box. I use the following plugin for dovecot with the daemon to provide Apple push mail for iPhones. https://github.com/st3fan/dovecot-xaps-daemon https://github.com/st3fan/dovecot-xaps-plugin For the most part, this works awesome but have run into a bit of a race issue with notification of mail in a particular instance. On my computer I use Outlook for Mac which says it supports IDLE but is broken. When an email comes in, I ALWAYS get the notification via the dovecpt plugin for a push since Outlook is checking IMAP every 2 minutes. On a buddy’s setup, he uses Apple Mail which supports IDLE that actually works. When his email client is connected from his laptop, it does actually maintain a persistent connection and NEVER receives a notification from the dovecot plugin because I’m guessing dovecot/deliver sees that the email was received by the desktop client. I’m not sure how to make the plugin ALWAYS give a push. Is it a dovecot config? A bug in the plugin? I’m not sure. Suggestions? Thank you, Steffan Cline 602-793-0014

how to treat synonymous domain names as one
by Nikolai Krot 08 Oct '15

08 Oct '15

Hallo List Users, I am curious if there is a way to rewrite domain name to another domain name. My goal is to provide authentication and mailboxes for the synonymous domains in a single source while keeping all other domains separate. I have setup: auth_username_format = %Lu mail_location = /var/vmail/%d/%u/Maildir in userdb/passdb (passwd-file): /etc/dovecot/%d/users Say I have two synonymous domain names my-domain-1.com my-long-named-domain-1.com I want both to resolve to my-domain-1.com when %d variable is used in Dovecot configs, so that passwd-file is /etc/dovecot/my-domain-1.com/users mailbox is /var/vmail/my-domain-1.com/user/Maildir while keeping other domains unchanged my-other-domain-2.com should resolve to: passwd-file is /etc/dovecot/my-other-domain-2.com/users mailbox is /var/vmail/my-other-domain-2.com/user/Maildir thanks, Nikolai

Dovecot don't erase mails from storage.

Hi, I have a dovecot installation with a strange problem: all the mails stays in storage after deleted from users mailbox. If user logon after the mails are deleted, they don't receive them any more, but the m.## files aren’t deleted. This happens with pop3 (default for this installation) and/or imap.

Compiling v2.2.19 - internal compiler error: segmentation fault (test-timing.c -> int64_t issue?)

Hi, I am trying to compile a 64-build of the latest dovecot v2.2.19 on my SuSE Linux Enterprise Server 10 (x64) system.

Released Pigeonhole v0.4.9 for Dovecot v2.2.19
by Stephan Bosch 04 Oct '15

04 Oct '15

Hello Dovecot users, Here is the definitive 0.4.9 release. Only a few minor fixes were done since RC1. Changelog v0.4.9: * Properly implemented checking of ABI version for Sieve interpreter plugins, much like Dovecot itself does for plugins. This will prevent plugin ABI mismatches. + Implemented a vnd.dovecot.environment extension. This builds upon the standard environment extension and adds a few more environment items, such as username and default mailbox. It also creates a variables namespace so that environment items can be accessed directly. I am still thinking about more environment items that can be added. + Sieve extprograms plugin: Made line endings of the input passed to the external programs configurable. This can be configured separately for each of the three extensions. + ManageSieve: Implemented proxy XCLIENT support. This allows the proxy to pass client information to the back-end. - ManageSieve: Fixed an assert failure occurring when a client disconnects during the GETSCRIPT command. - doveadm sieve plugin: Fixed incorrect initialization of mail user. This caused a few memory leaks. - sieve-filter command line tool: Fixed handling of failure-related implicit keep when there is an explicit default destination folder. This caused message duplication. - lib-sieve: Fixed bug in RFC5322 header folding. Words longer than the optimal line length caused empty lines in the output, which would break the resulting message header. This surfaced in References: headers with very long message IDs. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.9.tar… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.9.tar… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

v2.2.19 released
by Timo Sirainen 03 Oct '15

03 Oct '15

http://dovecot.org/releases/2.2/dovecot-2.2.19.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.19.tar.gz.sig * pop3_deleted_flag has been broken since v2.2.10. Using it would cause buffer overflows, which could be exploitable. However, this bug would have become visible quite soon after users had deleted some POP3 mails, because the pop3 processes would have started crashing all the time even in normal use. * "doveadm director flush" command has a changed meaning now: It safely moves users to their wanted backends, instead of simply forgetting the mapping entirely and leaving the existing connections untouched. Use -F parameter to get the original unsafe behavior. + Added imap-hibernate processes (see imap_hibernate_timeout setting). IDLEing IMAP connections can be hibernated, which saves memory. + Optimized tracking mailboxes' vsizes (= sum of all messages' sizes). If mailbox_list_index=yes, it's also stored in there. This makes it very efficient to look up vsizes for all mailboxes. + Added a quota "count" backend, which uses the mailbox vsizes to get the current quota usage. It requires using the new quota_vsizes=yes setting, which tracks the messages' "virtual sizes" rather than "physical sizes". Their distiction is minor and mostly irrelevant nowadays (if mail sizes should be counted with LF or CRLF newlines). + "doveadm director up/down" commands added. The monitoring script should be using these commands instead of changing the vhost count. This allows admin to manually disable a server by changing the vhost count to 0 without the monitoring script changing it back. + Added support for HAProxy protocol: http://wiki2.dovecot.org/HAProxy + Added push-notification plugin framework, which can be used to easily implement push notifications to various backends. Implemented "ox" backend for notifying Open-Xchange via HTTP/json. + imap_logout_format supports more variables now, e.g. number of deleted messages. + pop3: Added pop3_delete_type setting (related to pop3_deleted_flag). + plugin { fts_enforced=yes } setting now fails body searches unless it can be done via the full text search engine. + Added %{passdb:*} and %{userdb:*} variables to various places + auth: Added ":protected" suffix for passdb and userdb fields. If used, the field doesn't overwrite an existing field. + IMAP/POP3 proxy: If a backend server dies, avoid client reconnection spikes by slowly disconnecting clients over time. This is enabled by setting login_proxy_max_disconnect_delay=secs passdb extra field. + imap: Added new read-only METADATA entries: /private/specialuse, /shared/comment, /shared/admin + imap: If client disconnects in the middle of a command, log how long the command had been running. - mdbox: Rebuilding could have caused message's reference count to overflow the 16bit number in some situations, causing problems when trying to expunge the duplicates. - Various search fixes (fts, solr, tika, lib-charset, indexer) - Various virtual plugin fixes - Various fixes and optimizations to dsync, imapc and pop3-migration - imap: Various RFC compliancy and crash fixes to NOTIFY

Re: dovecot quota service for postfix
by Michael Peter 03 Oct '15

Hello, Thanks for the clarifications plugin { quota = maildir:User quota quota_rule = *:storage=1G quota_grace = 10%% # 10% is the default quota_status_success = DUNNO quota_status_nouser = DUNNO quota_status_overquota = "552 5.2.2 Mailbox is full" } The above configurations is my default for all users. but my mail system is using mbox format and not maildir.... so what should i change in the above configuration to use mbox INSTEAD of maildir ?? Also for the quota paramater, can i use (myquota = maildir:User quota) INSTEAD of (quota = maildir:User quota) ?? or it must "QUOTA =" and not any thing else to work ? same for quota_rule parameter, should i add (_rule) after quota to work ??? can i add for example qouta_restriction INSTEAD of quota_rules ?? i am asking this question to better understand how dovecot work.. also last question when i use the following command to get quota for existing system user called michael , it gives me an error as follow, so why dovecot is not able to get the quota for the system users? doveadm quota get -u michael doveadm(michael): Fatal: User doesn't exist Many thanks >> Incase user is underquota, then the email is returned back to postfix for >> processing and delivering email to user mbox, incase user has no sufficient quota then dovecot will inform postfix to reject email. Please confirm if what i mentioned above is correct and that i >> understand >> correctly how dove-cot policy works with postfix. > Your understanding is mor or less correct, except that postfix never passes the email itself to dovecot when performing the quota check. It simply sends a message to the quota policy service asking if the recipient is over quota.

imap_logout_format improvements / ideas
by Timo Sirainen 03 Oct '15

03 Oct '15

http://hg.dovecot.org/dovecot-2.2/rev/93bba97afb2a http://hg.dovecot.org/dovecot-2.2/rev/e0a17714f0c9 So all in all, you can now add to imap_logout_format: # %i - total number of bytes read from client # %o - total number of bytes sent to client # %{fetch_hdr_count} - Number of mails with mail header data sent to client # %{fetch_hdr_bytes} - Number of bytes with mail header data sent to client # %{fetch_body_count} - Number of mails with mail body data sent to client # %{fetch_body_bytes} - Number of bytes with mail body data sent to client # %{deleted} - Number of mails where client added \Deleted flag # %{expunged} - Number of mails that client expunged # %{trashed} - Number of mails that client copied/moved to the # special_use=\Trash mailbox. Any thoughts on what else would be useful? I was also thinking about separating (deletes and) expunges from Trash vs non-Trash, but I'm not sure how useful that would be (and what would it be called?) It's also a bit annoying that a copy+expunge to a Trash will return expunged=1 trashed=1, but a move to Trash (via IMAP MOVE) will return expunged=0 trashed=1. But trying to fix that would be too much trouble.

/usr/lib/dovecot/imap exits with an error if stderr closed
by Josh Triplett 01 Oct '15

01 Oct '15

At the end of a direct IMAP conversation with the imap binary, it writes an informative message like "imap(josh): Info: Connection closed in=0 out=365" to stderr. With stderr closed, the imap binary will exit with exit code 81 after it gets EBADF from that write. While it makes sense to fail on failure to write an error message, I don't think it makes sense to fail if writing an info message fails. I encountered this when using /usr/lib/dovecot/imap with mutt's "tunnel" option. Mutt seems to run the configured tunnel program with stderr closed, which triggers this error. - Josh Triplett

Dovecot 1.0.10 - Authenticate against LDAP with multiple sub-trees
by Daniel Heitepriem 01 Oct '15

01 Oct '15

Hi guys, I'm using Dovecot 1.0.10 with LDAP authentication. Below is my dovecot-ldap.conf { hosts = *IP of LDAP server* auth_bind = yes auth_bind_userdn = uid=%u,ou=people,dc=*something*,dc=com ldap_version = 3 base = %u,ou=people,dc=*something*,dc=com deref = never scope = subtree user_filter = (&(objectClass=person)(uid=%u)) } And the current structure: Base | |-- people | | *user entries* | Now I want to update to a LDAP server with the following structure: Base | |-- people | |-- staff | | *user entries* |-- other location | | *user entries* | How can I keep my "auth_bind_userdn" using this new structure? Hopefully somebody can help me :) Regards, Daniel

And every file is a hard link to /mail/users/attachments/27/d1/hashes/27d1904ac9947945bf48ea545ec278940d840ed1 For the documentation I have found, "27d1904ac9947945bf48ea545ec278940d840ed1" is a hash of the attach content, but what does the other part of the filename (the "090d88269ad28851f14b0000a9061514" means) My question has come to my mind because I need an easy way to find the mailbox where this attach is referenced from. -- Angel L.

Re: [IMAP] Nothing in INBOX

Your "mail" output states > "/var/mail/desktop": 20 messages 9 new 18 unread indicating that the INBOX is held in /var/mail/desktop, whereas your dovecot configuration states > mail_location = maildir:/var/mail/vhosts/%d/%n So there seems to be a disagreement as to where the INBOX is located. Maybe you need to set the INBOX parameter directly. http://wiki2.dovecot.org/MailLocation Joseph Tam <jtam.home(a)gmail.com>

userdb prefetch doesn't work with imapc (2.2.18)
by Nagy, Attila 30 Sep '15

30 Sep '15

Hi, I have the following config in dovecot 2.2.18: # doveconf -n userdb passdb userdb { driver = prefetch } passdb { args = host=127.0.0.1 port=1430 default_fields = userdb_imapc_user=%u userdb_imapc_password=%w driver = imap } I guess it should cause a single login to the backend IMAP server when issuing a LOGIN to dovecot. Yet, dovecot opens two TCP sessions. In the first, it issues a LOGIN and in the second it logs in again (LOGIN) and issues LIST "" "". At the end (after LOGIN succeeds to dovecot), only one of the two connections remain open to the backend server. Any ideas about this? Thanks,

v2.2.19 release candidate 2 released
by Timo Sirainen 30 Sep '15

30 Sep '15

http://dovecot.org/releases/2.2/rc/dovecot-2.2.19.rc2.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.19.rc2.tar.gz.sig There were still a bit too many bugs in RC1, so here's RC2. Hopefully this will be stable enough to become v2.2.19 final. Please test now rather than wait for v2.2.19 final, since v2.2.20 is unlikely to arrive anytime soon (unless there are some major problems). Some fixes since RC1: - dict fixes, especially with pgsql - virtual plugin crashfixes - quota "count" backend fixes - lib-http fixes - some compiling fixes

dovecot quota service for postfix
by Michael Peter 29 Sep '15

29 Sep '15

Hello, I am trying to use dovecot quota service for postfix in order set quota for some users. i configure postfix policy service to ask dovecot if user quota is sufficient to accept the email or not. (dovecot in this case acts only as policy server to postfix as it only ACCEPT/REJECT email according to user quota, but it is not used to deliver email , because postfix will deliver the email to user mailbox) Incase user is underquota, then the email is returned back to postfix for processing and delivering email to user mbox, incase user has no sufficient quota then dovecot will inform postfix to reject email. Please confirm if what i mentioned above is correct and that i understand correctly how dove-cot policy works with postfix. Kindly check my configuration below and advise the missing parts to add... plugin { quota_rule = *:storage=1G quota_grace = 10%% # 10% is the default quota_status_success = DUNNO quota_status_nouser = DUNNO quota_status_overquota = "552 5.2.2 Mailbox is full" ... } The above configurations is for all users which is not override by quota rules in userdb's extra fields in my password file below. Is the above configuration missing some thing ? i am using mbox format for emails storage. do you i have to add (quota= SOMETHING) before (quote_rule = *:storage=1G) and what to do add to make dovecot support mbox quota? smtpd_recipient_restrictions = check_policy_service inet:SERVER-HIDDEN-FOR-SECRUITY.com:12340 service quota-status { executable = quota-status -p postfix inet_listener { port = 12340 } client_limit = 1 } now in order to configure dovecot specific quota for user named (user1) i use passwd-file as follow user1:{plain}pass3:1002:1002::/home/user1::userdb_mail=mbox:~/mymail:INBOX=/var/mail/user1 userdb_quota_rule=*:bytes=300M All other users except users1 should have 1GB storage according to this configuration. which user1 will only have 300MB Please advise what is my configuration is missing and if i need to add any thing to run without issues. Many thanks Michael Peter

BINARY capability not working correctly?
by Jouko Nikula 29 Sep '15

29 Sep '15

Hello, I have trouble with some attachments not working on Horde and Roundcube. I made a ticket to Roundcube webmail and they tracked down it to Dovecot not responding correctly to BINARY FETCH: http://trac.roundcube.net/ticket/1490532 What is causing Dovecot to answer NIL? Is there an issue in Dovecot? If I want to disable to BINARY capability in Dovecot I need to use imap_capabilities. I found out that I could add capabilities with syntax imap_capabilities= +FOO but it seems I can't use similar syntax (imap_capabilities= -FOO) to remove capabilities? If I list all capabilities like: imap_capabilities= IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE MOVE QUOTA I understood that this will result in listing all capabilities already pre-login. Is this a problem? Thanks, Jouko Nikula

mirroring one domain.tld to domain.tld.au
by voytek＠sbt.net.au 29 Sep '15

29 Sep '15

I have Postfix/Dovecot/postfixadmin/MySQL with several virtual mailbox domains one of the domains is like aname.com.au, the user also now has aname.com, and, would like to 'mirror' most of the addresses to be user(a)aname.com, THOUGH, some are to remain as user2(a)aname.com.au so, both user(a)aname.com as well as user(a)aname.com.au should be one user the users retrive emails as user(a)aname.com.au longer term... some would want to use aname.com.au. some, aname.com what's the best/proper way to do so in Dovecot ? I think I can do Postfix with postfixadmin to "Mirror addresses of one of your domains to another." but what do I do at the Dovecot end...? thanks for any pointers, suggestions or advice

distuguish between different domains
by Andreas Meyer 29 Sep '15

29 Sep '15

Hello! I asked myself wether it is possible to distinguish between different doamins in dovecot so that a user only sees his mailbox when he is connecting with user1(a)aaa.de specifying the server with mail.aaa.de for example. So the server does not handout the mailbox for user1(a)bbb.de when the client connects to mail.aaa.de as user1(a)bbb.de I have this problem with roundcube. Dovecot is responisble for two domains. With roundcube I can login as user1(a)aaa.de altough the client is configured like so: $config['smtp_server'] = 'tls://mail.bbb.de'; and I am landing in the mailbox of user1(a)aaa.de Is there a way to striktly differentiate between doamins? Both domains have their own IP-addresses. Regards Andreas

Newbie why is dovecot classified diff then sendmail or courier
by David Niklas 29 Sep '15

29 Sep '15

Hello, this is probably a dumb question, but I can't for the life of me figure out why sendmail and courier are classified universally as network-mail-mta whereas dovecot is in places like network-mail-general or some such place. I've used several Linux distros and have noted this keenly (they also normally classify photorec, the HD recovery tool as hardware-photography,so this may just be a mistake). I'm concerned that I'm looking into the wrong software for an mail transport/delivery agent. Thanks, David

doveadm fetch line wrapping

The manual at http://wiki2.dovecot.org/Tools/Doveadm/Deduplicate tells how to estimate what will be expunged: > doveadm -f table fetch -u jane 'guid uid' mailbox a_Box | sort I wanted to learn the subjects: > doveadm -f table fetch -u jane 'guid hdr.Subject' mailbox a_Box In the output, long lines will be broken up, continuation lines starting with a blank (mostly), disabling the sort > doveadm -f table fetch -u jane 'guid hdr.Subject' mailbox a_Box \ > | sed -e :a -e '$!N;s/\n\s//;ta' -e 'P;D' | sort --stable Some (gnu) sed foo joins them back together, the sort works again :) -- peter

dovecot, fts, solr5 patch, fuzzy search
by Sergey Urushkin 28 Sep '15

28 Sep '15

Hi! I have a patch and several thoughts about FTS in dovecot. I. SOLR v5.1 and above doesn't allow GET /select queries with Content-Type header set, so, I just removed it from the code: --- dovecot-2.2.18/src/plugins/fts-solr/solr-connection.c 2015-05-13 17:14:45.000000000 +0300 +++ dovecot-2.2.18.patch/src/plugins/fts-solr/solr-connection.c 2015-09-27 19:47:40.363843359 +0300 @@ -432,7 +432,6 @@ solr_connection_select_response, conn); http_client_request_set_port(http_req, conn->http_port); http_client_request_set_ssl(http_req, conn->http_ssl); - http_client_request_add_header(http_req, "Content-Type", "text/xml"); http_client_request_submit(http_req); conn->request_status = 0; After that it works just fine. And it seems it doesn't hurt compatibility with older versions. Tested with 3.1, 3.6.2, 4.10.4, 5.3.1 So, I think this patch should be included. II. Fuzzy search. As I understand dovecot searches the same way despite FUZZY word is given or not. In my case I'd like to have an ability to make lookups like "domain.com usernamepart" (usernamepart - part of localpart). So, I use '<str name="defType">edismax</str><int name="qs">15</int>' inside requestHandler /select in solrconfig.xml. It's very convenient for users. Besides other things, this makes searches "abc@def" and "def@abc" identical to dovecot. But the problem is that sometimes the exact match is necessary. E.g. when using "doveadm expunge". For now I found a workaround - remove fts plugins while using doveadm with -o "`dovecot -n | sed -n 's/"//; s/ *= */=/; /^mail_plugins/s/$"\| fts\(\|_[^ ]\+$\)//gp'`". But I think users should have an ability to decide which search type to use. Here is what I'm suggesting: 1. Implement fts_fuzzy_default option (default - true, current behavior). false should disable fuzzy search by default. 2. Make a way for fts backend to choose which search type to use. For solr it would be an ability to specify: a) "handler" (default=select) and "handler_fuzzy" (default=select or handler's value) (the same as handler by default). After this you have to create second select-like handler with fuzzy capabilities in solrconfig.xml. Example: fts_solr = url=http://127.0.0.1:8983/solr/dovecot/ handler=select handler_fuzzy=select2 This method will use the same index for both search types. b) "url_fuzzy" URL (different solr core or even address/port), like this: fts_solr = url=http://127.0.0.1:8983/solr/dovecot/ url_fuzzy=http://127.0.0.1:8983/solr/dovecot_fuzzy/ This method will allow to have two completely different indexes. And according to RFC 6203 search query generally may be mixed (FUZZY/EXACT). Both options will be useful in different setups. Hope, these thoughts will help. -- Best regards, Sergey Urushkin

v2.2.19 release candidate released
by Greg Wildman 28 Sep '15

28 Sep '15

Hello, I am trying out 2.2.19.rc1 on a lightly loaded server with no problems so far. The reason I wanted to try 2.2.19.rc1 was to get access to the %{listener} variable in the auth phase so I can modify the SQL password_query according to which unix_listener is being queried. According to the docs, "These variables work only in Dovecot-auth and login_log_format_elements setting". I can confirm that %{listener} works in login_log_format_elements but it does not work if I use it in my SQL auth query. My logic is as follows: I create multiple listeners for different SASL authentications in 10 -master.conf service auth { unix_listener auth-userdb { mode = 0660 user = dovecot group = vmail } unix_listener exim-client { mode = 0660 user = dovecot group = exim } unix_listener xmpp-client { mode = 0660 user = dovecot group = mail } user = $default_internal_user } Now I want to use %{listener} in my SQL password_query in a case statement to auth according to which listener is being used. E.g. CASE '%{listener} ' \ WHEN 'exim-client' THEN ma.SMTPAUTH_allowed = 'YES' \ WHEN 'xmpp-client' THEN ma.XMPP_allowed = 'YES' \ ELSE ma.IMAP_allowed = 'YES' \ END Should the %{listener} variable work in this case ? -- Greg

modify message with doveadm?
by Frank-Ulrich Sommer 27 Sep '15

27 Sep '15

Hello, I'm using dovecot with getmail and spamassassin. To re-learn false detected mails I created two folders and use an external script that checks the corresponding maildir directories for changes (with inotifywait). The mails found in these directories are passed to sa-learn (to re-learn the correct classification) and then moved back to the inbox or the spam folder. To access the mail I use "doveadm search" (to find all mails in the two folders), "doveadm fetch" (to get the text and pass it to sa-learn) and "doveadm move" (to move the mail to the correct location. This works as desired, except that a mail once marked as spam will forever be marked as such. Spamassassin has the -d option to remove the markup, but I need to replace the original mail with the cleaned version. The only idea I got was deleting that mail and importing the cleaned one, but as I want to implement several "special" folders for further functionality with different IMAP clients I would prefer a "cleaner" solution. What would be the correct/best way to modify the mail body/header/text from an external tool? Kind regards, Frank

Sieve - multiple cores/CPUs
by Paweł Grzesik 25 Sep '15

25 Sep '15

Hi All, I have a quick question about the Sieve in Dovecot. I know that this is a plugin so probably it depends on the Dovecot itself but: is it able to use multiple cores/CPUs when doing the filtering? does the filtering for each mail user run on a separate core? Thanks, Pawel

Cyrus mailbox (plain files) to Dovecot
by Wolfgang Rosenauer 25 Sep '15

25 Sep '15

Hi, I'm migrating from a Cyrus to a Dovecot installation right now. As part of it I've got plain Cyrus mailboxes (w/o real metadata; so to say I've got the /var/spool/imap/user part but not the /var/lib/imap/user one)). Those former mailboxes I want to provide under a public namespace via ACLs. The question I cannot answer right now is: How can I convert these plain mailboxes on a FS level to maildir++ so I can provide them as public mailboxes on the new system? The tools I have found require a valid/complete cyrus mailbox. (I don't really care about message flags etc). Thanks, Wolfgang

v2.2.19 release candidate released
by Timo Sirainen 25 Sep '15

25 Sep '15

http://dovecot.org/releases/2.2/rc/dovecot-2.2.19.rc1.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.19.rc1.tar.gz.sig A lot of changes since v2.2.18, so here's a release candidate first. If no bugs are reported, I'm planning on making the final release sometimes this week. The most interesting new features here are the imap-hibernate process, quota count backend and director/proxy improvements. * "doveadm director flush" command has a changed meaning now: It safely moves users to their wanted backends, instead of simply forgetting the mapping entirely and leaving the existing connections untouched. Use -F parameter to get the original unsafe behavior. + Added support for imap-hiberanate processes. + Optimized tracking mailboxes' vsizes (= sum of all messages' size). If mailbox_list_index=yes, it's also stored in there. This makes it very efficient to look up vsizes for all mailboxes. + Added a quota "count" backend, which uses the mailbox vsizes to get the current quota usage. It requires using the new quota_vsizes=yes setting, which tracks the messages' "virtual sizes" rather than "physical sizes". Their distiction is minor and mostly irrelevant nowadays (if mail sizes should be counted with LF or CRLF newlines). + "doveadm director up/down" commands added. The monitoring script should be using these commands instead of changing the vhost count. This allows admin to manually disable a server by changing the vhost count to 0 without the monitoring script changing it back. + Added support for HAProxy protocol: http://wiki2.dovecot.org/HAProxy + Added push-notification plugin framework, which can be used to easily implement push notifications to various backends. Implemented "ox" backend for notifying Open-Xchange via HTTP/json. + imap_logout_format supports more variables now, e.g. number of deleted messages. + pop3: Added pop3_delete_type setting (related to pop3_deleted_flag). + plugin { fts_enforced=yes } setting now fails body searches unless it can be done via the full text search engine. + Added %{passdb:*} and %{userdb:*} variables to various places + auth: Added ":protected" suffix for passdb and userdb fields. If used, the field doesn't overwrite an existing field. + IMAP/POP3 proxy: If a backend server dies, avoid client reconnection spikes by slowly disconnecting clients over time. This is enabled by setting login_proxy_max_disconnect_delay=secs passdb extra field. + imap: Added new read-only METADATA entries: /private/specialuse, /shared/comment, /shared/admin + imap: If client disconnects in the middle of a command, log how long the command had been running. - mdbox: Rebuilding could have caused message's reference count to overflow the 16bit number in some situations, causing problems when trying to expunge the duplicates. - Various search fixes (fts, solr, tika, lib-charset, indexer) - Various virtual plugin fixes - Various fixes and optimizations to dsync, imapc and pop3-migration - imap: Various RFC compliancy and crash fixes to NOTIFY

Released Pigeonhole v0.4.9.rc1 for Dovecot v2.2.19.rc1
by Stephan Bosch 24 Sep '15

24 Sep '15

Hello Dovecot users, Here's the Pigeonhole RC that goes with the Dovecot RC. Changelog v0.4.9.rc1: * Properly implemented checking of ABI version for Sieve interpreter plugins, much like Dovecot itself does for plugins. This will prevent plugin ABI mismatches. + Implemented a vnd.dovecot.environment extension. This builds upon the standard environment extension and adds a few more environment items, such as username and default mailbox. It also creates a variables namespace so that environment items can be accessed directly. I am still thinking about more environment items that can be added. + Sieve extprograms plugin: Made line endings of the input passed to the external programs configurable. This can be configured separately for each of the three extensions. + ManageSieve: Implemented proxy XCLIENT support. This allows the proxy to pass client information to the back-end. - ManageSieve: Fixed an assert failure occurring when a client disconnects during the GETSCRIPT command. - doveadm sieve plugin: Fixed incorrect initialization of mail user. This caused a few memory leaks. - sieve-filter command line tool: Fixed handling of failure-related implicit keep when there is an explicit default destination folder. This caused message duplication. - lib-sieve: Fixed bug in RFC5322 header folding. Words longer than the optimal line length caused empty lines in the output, which would break the resulting message header. This surfaced in References: headers with very long message IDs. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.9.rc1… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.9.rc1… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

dict lookup from quota plugin
by Bjørnar Ness 23 Sep '15

23 Sep '15

I am having trouble with using a custom daemon listening on a socket together with the quota plugin. My configuration is: quota = dict:User quota::dict:/tmp/dovecot-proxy-dict:: The problem is that dovecot sends keys without usernames, for example: priv/quota/storage Is it possible to get around this limitation without code modification? Also, is it planned to support the "new-style" userdb/passdb lookups from other plugins? -- Bj(/)rnar

bug - over system quota and dovecot-uidlist
by krzf83＠gmail.com 23 Sep '15

23 Sep '15

Ever since I've migraded from courier pop3 to dovecot pop3 I'm constantly getting complains from users that went over system quota for short while and then their pop3 client downloads all messages again. I never happened with courier pop3. I think that dovecot does not handle dovecot-uidlist file safely so it can withstand such situations. rsync and other similar programs always writes to a copy of the file like dovecot-uidlis.xcb453 and on success unlinks old file and renames new one. Dovecot should not assume that write operation on dovecot-uidlist will succeed. Yes, I know I can put metadata like dovecot-uidlist somewhere else, on another partition but that really splits mailbox into multiple locations making for example backups way harder to make, restore, share etc.

Dovecot proxy ignores trusted root certificate store
by Alex Bulan 22 Sep '15

22 Sep '15

Dovecot v2.2.18 OS: FreeBSD 10.1/amd64 Dovecot in proxy mode ignores the root certificate store and can't verify the backend's SSL certificate. I've pointed ssl_client_ca_file to my root certificate store, but I suspect ssl_client_ca_file is only used in imapc context. It seems to be ignored in proxy context. doveconf -n ssl_client_ca_file: ssl_client_ca_file = /usr/local/share/certs/ca-root-nss.crt In my password_query I return host set to the backend's IP address, starttls='yes', proxy='y'. The backend's certificate chain is correct and it verifies successfully with "openssl s_client -connect x.x.x.x:110 -starttls pop3 -CAfile /usr/local/share/certs/ca-root-nss.crt". But the Dovecot proxy fails to verify the intermediate certificate it receives from the backend. The inode atime of ca-root-nss.crt is never updated, either at Dovecot start or when it connects to the backend, so Dovecot (via the openssl library) never reads the file.

2.2.18 Regression: Incorrect STATUS response for virtual mailboxes
by Guilhem Moulin 22 Sep '15

sieve_extprograms - run any individual script?
by Hajo Locke 22 Sep '15

22 Sep '15

Hello, i use sieve extension sieve_extprograms to send incoming mail to some script. For security reasons it is needed that script-paths etc. are registered in dovecot.conf This is my current dovecot.conf plugin { sieve = ~/.dovecot.sieve sieve_plugins = sieve_extprograms sieve_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter +vnd.dovecot.execute sieve_pipe_bin_dir = /usr/local/bin/ sieve_filter_bin_dir = /usr/local/bin/ } .dovecot.sieve example: if address "to" "test(a)example.com" { filter "myfilter"; } This is all working without problems. Is there a possibility to allow users the execution of individual scripts in own homepath? Some people need to pipe mails to scripts for immediately processing (some ticketsystems need this). Is there a way to make this possible with sieve? Thanks, Hajo

Multiple passwords for a user (SQL)
by Marco Fretz 22 Sep '15

22 Sep '15

Hi everyone, I'm not sure if this has been discuessed already as I coun't find anything in the archives - maybe I'm looking for the wrong thing. I want to build something similar to googles "app passwords" where your use a different password (strong, auto generated) for each device / app. In general I think this is pretty easy on the database side as I just need a password table and link say the passwords with an user_id to the corresponding user in the users table - one use has many passwords (1:n). for dovecot this means that it will get multiple rows with passwords back from the "password_query". is there a way to tell dovecot to check all those returned passwords and "pass" the request if one of those passwords match? thank you, best regards Marco

[Dovecot] Pigeonhole sieve re-filter extension?
by T.B. 22 Sep '15

22 Sep '15

Dear Stephan Bosch, dear Dovecot community, "sieve-filter" re-filtering of existing mails is already a great progress for everyone using sieve! But as far as I know this functionality is just accessible by the server administrator. In the meanwhile everyone knows the comfort of re-executing filter scripts on his own existing mailboxes - triggered by himself! This service is already very widespread. Examples are MUA's like Outlook or Thunderbird which provide this service just on the client side. Or almost every web-mail provider offers this. Is there already an managesieve protocol extension that allows client triggered server side re-filtering? If not, maybe you could design a RFC for this? What do you think? Best regards. T.B.

ssl_key_password loaded from file: 'Couldn't parse private ssl_key'

As this is my first message to this ML: Hello! I am using a password-protected SSL key for my dovecot MDA. When I tried to use the ssl_key_password configuration directive as follow: ssl_key_password = </path/to/passfile it did not work as I logged the following: dovecot: imap-login: Error: SSL: Stacked error: error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt dovecot: imap-login: Fatal: Couldn't parse private ssl_key: error:0906A065:PEM routines:PEM_do_header:bad decrypt However, not using the fille inclusion but directly configuring as follow: ssl_key_password = mypass did work... I am loading my certificate & key with the file inclusion trick... How come cannot I use that for the password file? It would avoid input the password directly into the dovecot configuraiton files, forcing me to change permissions and duplicating it... When renewing the private key I will be force to edit the password at every location. Is it a bug? or a feature? :D --- *B. R.*

Messages lost from imap folders
by Nikolaos Milas 19 Sep '15

19 Sep '15

Hello, We have one user who is complaining that he has lost mails from 3 imap folders, administered through squirrelmail. The folders suddenly appeared unregistered, and once manually registered they were empty. Has anyone observed something like this? We are running two servers (as VMs) with Dovecot v2.2.18, synced (two-way) using dsync. The configurations follow. Can you please help me understand what may have gone wrong? Can I try to find actions regarding these folders in the logs? What should I search for? Could this be an issue involving dsync? How can I trace back dsync activity in detail? Server configs follow (I have only altered the real domain name and the login greeting.)

thanks very much urban. this was very helpful. i have around 12500 users spread over 3 independent servers each having around 4000+ users i am using qmailtoaster, vpopmail, spamassassin and dovecot. in future i am planning to consolidate all using a HA cluster. if it is ok with you could you kindly share some information about your email server configuration. if you do not wish to put it on the list then you can directly email me. 1) is your email volume high ? 2) server hardware to support 28000 users 3) mailserver software - exim or postfix ??. 4) antispam software like spamassassin if any also if you have faced any email re-download issues with dovecot sometimes randomly incase of pop3 users storing emails on the server ? thanks rajesh ----- Original Message ----- From: Urban Loesch [mailto:bind@enas.net] To: dovecot(a)dovecot.org Sent: Sun, 13 Sep 2015 09:33:14 +0200 Subject: Re: concerning dovecot settings for high volume server Hi, I have running dovecot with about 28k users.

restrict map-login by geoip?
by Terry Barnum 17 Sep '15

17 Sep '15

Is there a way to restrict my user logins from a set of IPs? For example, all my users are in the US so there shouldn't be any logins from other countries. Can I tell dovecot to restrict logins to a CIDR list of US IPs? Can someone point me to docs on how to set this up? I've searched but haven't found how to accomplish this. Thanks, -Terry Terry Barnum digital OutPost http://www.dop.com

New created users can not log in

Hi, I am using dovecot 2.2 for some time. All users on the system can log in using Horde Webmail. But now, after creating a new user on the server with <useradd -m username> this new user is not able to log in. Of course I have set a password for the new user. In the log file I can see: Sep 16 23:04:05 servername auth: gkr-pam: error looking up user information Sep 16 23:04:07 servername HORDE: [imp] [login] Authentication failed.

How to "Windows Authenticate"
by Mark Foley 16 Sep '15

16 Sep '15

I've been using Dovecot 2.2.15 as the IMAP server for Outlook (2010/2013) on Windows workstations for over 6 months with no problems. Dovecot is hosted on the office Samba4 AC/DC server. I have been using auth_mechanisms plain login, and passdb driver = shadow. What I'd like to do now is use the "Windows Authenticated" login so I don't have to have separate passwords for users logging into the Windows AD workstations and their Outlook clients. If anyone has actually done this I'd appreciate some tips. My various attempts have not been successful. Here is my current config: $ doveconf -n # 2.2.15: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.10.17 x86_64 Slackware 14.1 auth_debug_passwords = yes auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no info_log_path = /var/log/dovecot_info mail_location = maildir:~/Maildir passdb { driver = shadow } protocols = imap ssl_cert = </etc/ssl/certs/OHPRS/GoDaddy/Apache/c5fe0cc8242d6030.crt ssl_key = </etc/ssl/certs/OHPRS/GoDaddy/mail.ohprs.org.key userdb { driver = passwd } verbose_ssl = yes Thanks, Mark Foley

FreeBSD 10 & default_vsz_limit causing reboots?
by Rick Romero 15 Sep '15

15 Sep '15

Ok, So this is really more of an observation than anything else. I had a FreeBSD 10.1 server that was running great. Some SSL issue came up, or I upgrade Dovecot in ports - something occurred and the machine started rebooting randomly. It would run for 2 weeks, then reboot. It might run for 5 days and then reboot. So I started doing more FreeBSD upgrades, thinking it was a kernel issue. The reboots only increased. This weekend I started thinking I might actually be having hardware issues. But, since I don't have easy physical access to the box and it's REALLY under loaded, I figured what the hell and upraded to 10.2 on Sunday. I think it rebooted 4 times after that on Sunday, and then another 2 times Monday morning. Its worth noting that while I have crash dumps enabled, they don't seem to be occurring. So hardware is still a possibility. After the 2nd Monday morning reboot, I started to wonder if there was some sort of process issue. Besides the OS upgrades - I had been monitoring the Dovecot logs for when the process limits are reached, and increasing them. It's a 'big' box, and load is typically between .30 and .50. CPUs aren't overtaxed, and most of the memory is dedicated to ZFS. The reboots are so short, I've only received one 'down' alert due to them. So it's a conerning issue, but not really impacting production. On a whim I changed my default_vsz_limit (as I had been increasing every other limit but that) from 384M to 512M. The system hasn't rebooted in 24hours. Now that could be a coincidence, but I thought I'd at least put it out there. If you see anything weird in my dovecot config, let me know - My config was originally vpopmail, but over time I've migrated to SQL-only. root@romulus:/usr/local/etc/dovecot # dovecot -n # 2.2.18: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 10.2-RELEASE amd64 auth_master_user_separator = * auth_mechanisms = plain login auth_username_translation = %@ auth_verbose = yes default_login_user = dovecot default_vsz_limit = 512 M disable_plaintext_auth = no first_valid_gid = 89 first_valid_uid = 89 last_valid_gid = 89 last_valid_uid = 89 log_path = /dev/stderr login_greeting = Ready. login_trusted_networks = 172.16.100.0/24 mail_fsync = never mail_plugins = " quota zlib stats" mail_privileged_group = mail namespace compat { alias_for = hidden = yes inbox = no list = no location = prefix = INBOX. separator = . } namespace inbox { inbox = yes location = prefix = separator = . } passdb { args = /usr/local/etc/dovecot/dovecot-master-sql.conf driver = sql master = yes pass = yes } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf driver = sql } plugin { quota = maildir quota_rule = Trash:storage=+10%% stats_refresh = 30 secs stats_track_cmds = yes } protocols = imap pop3 service anvil { client_limit = 3175 } service auth { client_limit = 3684 unix_listener auth-master { mode = 0600 } } service imap-login { process_limit = 1536 process_min_avail = 25 service_count = 1 } service imap-postlogin { executable = script-login rawlog /usr/local/etc/dovecot/lastauth-imap.sh user = vpopmail } service imap { executable = /usr/local/libexec/dovecot/imap imap-postlogin process_limit = 1536 } service pop-postlogin { executable = script-login /usr/local/etc/dovecot/lastauth-pop.sh user = vpopmail } service pop3-login { process_limit = 1536 process_min_avail = 15 service_count = 1 } service pop3 { executable = /usr/local/libexec/dovecot/pop3 pop-postlogin } service stats { fifo_listener stats-mail { mode = 0600 user = vpopmail } } shutdown_clients = no ssl_cert = </etc/ssl/mail.pem ssl_key = </etc/ssl/mail.key ssl_key_password = na userdb { driver = prefetch } verbose_proctitle = yes protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep mail_max_userip_connections = 100 mail_plugins = " quota zlib stats imap_zlib quota imap_quota" } protocol pop3 { mail_max_userip_connections = 100 mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv }

Dovecot does not accept new connection with error "imap-login: Error: read(anvil) failed: EOF"
by Julien Fastré 14 Sep '15

14 Sep '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, First of all, thank you for the work the contributors are doing with Dovecot ! Dovecot is doing a great job ! I am encountering a problem with a configuration and, despite my search on the web, I do not find any solution for this problem. Dovecot seems to stop accepting new connection. The users : - - can not save sent messages to "Sent" folder (using Thunderbird) ; - - can not connect or retrieve message from webmail (using sogo or roundcube) In the log, I see this error : > Jun 30 13:54:53 mail dovecot: imap-login: Error: read(anvil) > failed: EOF Jun 30 13:54:53 mail dovecot: message repeated 2 times: > [ imap-login: Error: read(anvil) failed: EOF] (the message may be repeated more than 2 times) It happens... sometimes. Manually restarting the dovecot service make the software working again. By searching on the web, I regularly see this statement in logs : > dovecot: auth: Error: read(anvil-auth-penalty) failed: EOF like here : http://www.dovecot.org/list/dovecot/2010-November/054694.htm l But it doesn't seem to be the same problem as mine (anvil / anvil-auth-penalty). The problem happens during peak load. Sometimes it happens twice a week, sometimes it may spent two month without any problem (during holidays, I did not had any problem).

Need help on checkpassword userdb/passdb
by Mark Foley 13 Sep '15

13 Sep '15

I'm experimenting with checkpassword as an auth method for usedb and passdb (http://wiki2.dovecot.org/AuthDatabase/CheckPassword) I've set up the userdb and passdb *exactly* as the wiki suggests as the "standard way": passdb { driver = checkpassword args = /user/util/bin/checkpassword } userdb { driver = prefetch } I've created a checkpassword program that does receive the correct user and password from dovecot. And I am successfully authenticating with ntlm_auth and exiting with status 0. My debug output: AUTHORIZED: (null) USER: (null) userdb_uid: (null) userdb_gid: (null) arg1=/usr/local/libexec/dovecot/checkpassword-reply CMD: /usr/bin/ntlm_auth --username="mark" --password='mypass' ntlm_auth status: 0 Now, the wiki says 2 things that have me stumped: 1. It says that, "Dovecot calls the script with AUTHORIZED=1 environment set when performing a userdb lookup. The script must acknowledge this by changing the environment to AUTHORIZED=2, otherwise the lookup fails." As you can see from my program log, "AUTHORIZED" is not set. Why? Nor are any of the other environment variables mentioned in the wiki. I've listed all the environment variables that *are* passed to the program at the bottom of this message. 2. The wiki says, "Your program received a path to checkpassword-reply binary as the first parameter. Execute it." I did so as a fork() and then execve("/usr/local/libexec/dovecot/checkpassword-reply") How do I know it worked ... or failed? What am I doing wrong?

Dovecot CalDAV server
by Timo Sirainen 11 Sep '15

11 Sep '15

I've been once in a while over the years thinking about implementing CalDAV (and CardDAV) to Dovecot. It might be time to start that soon. Does anyone have any suggestions? So far my main goals would be: - scalable, of course - configurable storage (object storage, regular fs, maybe some key-value dbs, maybe storing as emails) - efficient indexes (potentially using key-value dbs? or maybe just local files. not sure yet what kind of indexing is needed) - have it work with dsync (= replication & migration) Some things I wonder about: - Maybe there is already some code out there that could be used to implement it faster? - Maybe even use something else besides C to implement it.. Then again that makes integration to Dovecot more difficult. - Is anybody interested in helping to develop this? :) I think I still have too much other work that I won't spend a lot of time coding it.. One thing that makes this easier is that Open-Xchange has already implemented a CalDAV server, so they can help to avoid the biggest design mistakes. (There are a couple of reasons why they'd want to replace that.)

My dovecot works fine against Active Directory 2003, but not against AD2008
by Fran 10 Sep '15

10 Sep '15

Hello, my dovecot installation has been working fine against AD till we upgrade from AD 2003 to AD 2008. As http://wiki2.dovecot.org/AuthDatabase/LDAP said, now I'm not able to connect AD through 389 port. The port 3268 works fine though. (...) Sep 7 19:02:05 <dovecotServer> dovecot: imap-login: Error: master(imap): Auth request timed out (received 0/12 bytes) Sep 7 19:02:05 <dovecotServer> dovecot: imap-login: Internal login failure (pid=4846 id=1) (internal failure, 1 successful auths): user=<<username>>, method=PLAIN, rip=<clientLAN_IP>, lip=<dovecotServer_IP>, TLS, session=<T+grMCsfqgAKHyZV> (...) Sep 7 19:02:06 <dovecotServer> dovecot: auth: Error: ldap(<username>,<clientLAN_IP>,<ZjyONSsf6QAKHyZV>): Connection appears to be hanging, reconnecting Sep 7 19:02:06 <dovecotServer> dovecot: auth: Error: ldap(<username>,<clientLAN_IP>,<T+grMCsfqgAKHyZV>): LDAP search returned multiple entries (...) Is there a technical reason for this problem? Does it exist any workaround? The use of Global Catalog (port 3268) is not a solution for me, since it misses many attributes. (ex. I use the field "initials" to set the quota and this field is not available through port 3268). I also noticed that, now, it uses any DC available in the domain, it doesn't care what I configured in "hosts = " parameter. This is using "hosts = dc03.domain:389": ----------------------------------------------- [root@<dovecotServer> ~]# netstat -anp | grep dovecot | grep auth tcp 22 0 <dovecotServer_IP>:55217 <dc03.domain_IP>:389 ESTABLISHED 4872/dovecot/auth tcp 22 0 <dovecotServer_IP>:57645 <dc06.domain_IP>:389 ESTABLISHED 4872/dovecot/auth tcp 0 0 <dovecotServer_IP>:55216 <dc03.domain_IP>:389 ESTABLISHED 4872/dovecot/auth It looks like it does a look up for other domains controller (I don't know how nor why) and it connect aleatory to any DC in my domain (in this case dc06.domain, but it changes any time), additionally to the configured one (dc03.domain).

Convert from Maildir to Mdbox
by J. Echter 09 Sep '15

09 Sep '15

Hi, i'd like to convert from maildir to mdbox. what would be the best way to do this? i have read the dsync part of the dovecot wiki but i don't get what i have to use for my setup. my dovecot.conf (the snippets i think would matter): mail_gid = 5000 mail_home = /DATEN/vmail/%d/%n mail_location = maildir:/DATEN/vmail/%d/%n/mail/ mail_plugins = " zlib" mail_uid = 5000 Thanks for your input.

[Dovecot] dsync replication errors
by Oli Schacher 09 Sep '15

09 Sep '15

Hi I'm trying to build a cluster of two servers with dsync replication (based on http://wiki2.dovecot.org/Replication) My test setup works fine for very simple tests, I can log in to both servers, copy a message to one of the servers and it successfully apperars in the other account. But, if I try to copy a large amount of messages at once to one of the accounts, my maillogs get flodded with errors(see below) and the mailboxes seem to get out of sync and messages are duplicated over and over again (I originally copied 100 messages and ended up with thousands in both mailboxes until I killed dovecot) I'd appreciate if someone could have a look at my config and tell me what I did wrong. dovecot.conf of both servers, they are identical except for the target ip in mail_replica: dovecot -n # 2.2.beta1 (070ca24e5846+): /etc/dovecot/dovecot.conf # OS: Linux

sieve_extprograms - double linebreaks at filtering
by Hajo Locke 09 Sep '15

09 Sep '15

Hello List, i have a problem when using sieve-plugin sieve_extprograms. I use dovecot 2.2.18 and bundled pigeonhole 0.4.6 (Ubuntu 14.04.3 LTS) i have enabled sieve_extprograms and vnd.dovecot.filter to send mail to user-defined script and get changed content back. My script previously was used with procmail and is working fine. Using same script with vnd.dovecot.filter leads to odd behavior. I already found out the problem itself: By sending Mailcontent to filter-programm it seems that sieve/sieve_extprograms is adding additional linebreaks to every line of complete mail. Please see this image to clarify: http://r31i.imgup.net/header8d56.jpg?l=de Every lineending got additional windows-lineendings, which leads to problems with processing scripts. Piping mails by procmail to same script is working without problems, because this mails are recieved "clean" without the "^M". this is part of dovecot.conf: plugin { sieve = ~/.dovecot.sieve sieve_plugins = sieve_extprograms sieve_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter +vnd.dovecot.execute sieve_pipe_bin_dir = /usr/local/bin/ sieve_filter_bin_dir = /usr/local/bin/ } this is part of userscript ~/.dovecot.sieve: require ["fileinto", "vacation", "variables", "envelope", "imap4flags", "vnd.dovecot.filter", "subaddress"]; if address "to" "test2(a)example.com" { filter "my-script"; } my-script currently just recieves and saves raw-data, so i could find difference between sieve and procmail mails. What to do here? Is this a kind of bug of sieve/sieve_extprograms or i have to use additional parameters? Thanks, Hajo

Problems setting up SIS (duplicate files with same hash)
by Joe Beaubien 09 Sep '15

09 Sep '15

Hi everyone, I am currently trying to setup our next dovecot server (2.2.18) with SIS enabled, but I have enconutered 1 problem and 1 question: *1) Same attachment, different filenames* I have a feeling a misconfigured something (or forgot to do something) because SIS almost works, but not quite since 3 identical attachment take 3x the space (see end of email for my SIS config). For 3 the emails I sent with the same attachment, I got 3 seperate files with the same hash name but a different string following the dash: -rw------- 1 info info 2.6M Sep 5 11:14 e35083e3280a21c6aaabbae8cb23d54493f514a5-6a22711a7b05eb5509480000045c9bf4 -rw------- 1 info info 2.6M Sep 5 11:16 e35083e3280a21c6aaabbae8cb23d54493f514a5-6c22711a7b05eb5509480000045c9bf4 -rw------- 2 info info 2.6M Sep 5 11:18 e35083e3280a21c6aaabbae8cb23d54493f514a5-6e22711a7b05eb5509480000045c9bf4 drwx------ 2 info info 4.0K Sep 5 11:18 hashes For the record, the "hashes" subfolder has only 1 hash (e35083e3280a21c6aaabbae8cb23d54493f514a5) which perfectly matches the first part of the 3 filenames. *2) Saving attachments under a generic name or more flexible permissions?* It seems that dovecot saves the attachment with the username and group of the user who has received the email. Is it possible to have dovecot save the attachments as a generic user (like dovecot or dovenull) so that all my different users can share the same pool of attachments? Alternatively, is it possible to have dovecot save the attachment under more flexible permissions so that they can be shared between users? This would allow us to save alot of disk space. *Here is the SIS config I am using:* mail_attachment_dir = /data/emails/attachments #mail_attachment_min_size = 128k #mail_attachment_fs = sis posix #mail_attachment_hash = %{sha1} Any help would be very much appreciated. Thank you, Joe B

Dovecot and IPA
by Kanwar Ranbir Sandhu 08 Sep '15

08 Sep '15

Hello, I'm trying to get Dovecot to use GSSAPI for authentication. I have an IPA server on CentOS 7 with a bunch of my servers attached to the IPA domain, including the server running Dovecot. I've followed official documentation from Red Hat and read numerous wiki articles on how to configure Dovecot to get it to use GSSAPI correctly. I don't think I've done anything incorrectly, but it refuses to work. This is the error I'm seeing: mailman02 dovecot: imap-login: Disconnected (tried to use unsupported auth mechanism): user=<>, method=PLAIN, rip=1.1.1.1, lip=2.2.2.2, TLS, session=<QhWSqxofyAAKyAkM> I don't understand why no username is being passed. My mail client is Evolution 3.10.4. FYI, Dovecot does work fine using a user/password file. I'm just trying to switch it over to GSSAPI so that I can manage passwords from one system. Any help would be appreciated. Regards, Ranbir -- Kanwar R.S. Sandhu

Multiple vacation
by Michele Locati 08 Sep '15

08 Sep '15

Hi all I'm using Dovecot 2.2.9 and I'm having problems configuring multiple vacation actions. The problem is that I'd like to have two different senders and two different messages, selecting the correct case by the recipient email address. I mean, if someone writes me to my email address "to-address1(a)example.com" I'd like to answer from "from-address1(a)example.com" with the message "TEST 1". If someone writes me to my email address "to-address2(a)example.com" I'd like to answer from "from-address2(a)example.com" with the message "TEST 2". Here's my script: require ["fileinto","vacation"]; vacation :addresses ["to-address1(a)example.com"] :from " from-address1(a)example.com" text: TEST 1 . ; } vacation :addresses ["to-address2(a)example.com"] :from " from-address2(a)example.com" text: TEST 2 . ; But the vacation filter doesn't work, and I see this message in the log file: main script: line X: error: duplicate vacation action not allowed (previously triggered one was here: main script: line Y). Is there a way to allow multiple vacation actions? Thank you Michele

Public folder subscriptions with Outlook
by Paul Tansom 08 Sep '15

08 Sep '15

This is more an Outlook issue than Dovecot, but given that it is connected to Dovecot I figured there would be a good pool of knowledge here that increases the likelihood that somebody knows the answer :) I have a Dovecot server setup with a public folder and keep getting complaints that Outlook users don't see new folders created by other people. In Thunderbird it is simply a case of unchecking the box to only show subscribed folders, but I can't find a way to do this in Outlook. The only thing I can think of is putting a script on the server to check for new folders and update each users subcriptions file, but I'm not completely happy with that solution! Any suggestions welcome. -- Paul Tansom | Aptanet Ltd. | https://www.aptanet.com/ | 023 9238 0001 Vice Chair, FSB Portsmouth & SE Hampshire Branch | http://www.fsb.org.uk/ ============================================================================= Registered in England | Company No: 4905028 | Registered Office: Ralls House, Parklands Business Park, Forrest Road, Denmead, Waterlooville, Hants, PO7 6XP

Different behavior of ACLs in MUA and doveadm
by Thomas Leuxner 08 Sep '15

08 Sep '15

I have noticed a difference in the behavior of ACLs. When used in a MUA the following global ACL works fine and has the desired effect - new mailboxes can be created by a user being part of the 'PublicMailboxAdmins' group: [ global-acl: ] INBOX owner lrwstiekxap Public/* group=PublicMailboxAdmins lrwsipk Public/* anyone lr Public/* authenticated lrws Creating the same mailbox via doveadm however fails with a permission problem: doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=public, prefix=Public/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=no location=mdbox:/var/vmail/public:INDEXPVT=~/mdbox/public doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/public, index=, indexpvt=/var/vmail/domains/leuxner.net/tlx/mdbox/public, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 0 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=private, prefix=Virtual/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=virtual:~/mdbox/virtual doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/domains/leuxner.net/tlx/mdbox/virtual, index=, indexpvt=, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 1 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/dovecot-acl not found doveadm(tlx(a)leuxner.net): Error: Can't create mailbox Public/Archive/Newsletters/heise-security/2014: Permission denied Interestingly, doveadm succeeds when dovecot-acl is present in the namespace root - which of course is not desirable in the light of the global ACL: [ dovecot-acl: ] group=PublicMailboxAdmins lrwsipk doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=public, prefix=Public/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=no location=mdbox:/var/vmail/public:INDEXPVT=~/mdbox/public doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/public, index=, indexpvt=/var/vmail/domains/leuxner.net/tlx/mdbox/public, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 0 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=private, prefix=Virtual/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=virtual:~/mdbox/virtual doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/domains/leuxner.net/tlx/mdbox/virtual, index=, indexpvt=, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 1 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: acl vfile: reading file /var/vmail/public/mailboxes/dovecot-acl doveadm(tlx(a)leuxner.net): Debug: Namespace Public/: /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014 doesn't exist yet, using default permissions doveadm(tlx(a)leuxner.net): Debug: Namespace Public/: Using permissions from /var/vmail/public: mode=0700 gid=default doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/dbox-Mails/dovecot-acl not found doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014/dbox-Mails/dovecot-acl not found doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014/dbox-Mails/dovecot-acl not found doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014/dbox-Mails/dovecot-acl not found # 2.2.15 (6078354e6238): /etc/dovecot/dovecot.conf I know there have been some changes in Mercurial as to how global ACLs are interpreted. Is doveadm probably behind on them? Regards Thomas

Fetch command response questions
by Vlad Pop 08 Sep '15

08 Sep '15

Hello, I have the following issue: When using command FETCH 2 (BODY.PEEK[HEADER] UID INTERNALDATE FLAGS BODYSTRUCTURE) on 2 different emails, we get 2 different response structure. First response structure contains the BODYSTRUCTURE in a single line, while in the second response, the BODYSTRUCTURE is divided into multiple lines with "{61}" character at the end of each line. The difference between those 2 emails is the name of some attachments. The attachment is an .eml file named "Re: [SR-Users] Keep-Alive in dialog "freeing a free fragment"" Is this a sort of bug or is it correct to receive the BODYSTRUCTURE on multiple lines? Vlad Pop

segfault when using zlib module with glibc 2.22
by Florian Pritz 08 Sep '15

08 Sep '15

Hi, I'm seeing the following segfault when I run `doveadm search mailbox inbox` with the zlib module enabled with dovecot 2.18 and glibc 2.22 on Arch Linux. It does not happen with glibc 2.21. I've noticed that when I remove "zlib" from the mail_plugins line at the beginning of the config file the segfault goes away. I've also tested hg tip and the problem does not appear to be fixed yet. The segfault also happens with other commands like `doveadm purge`. Do you need any more information to reproduce and fix this?

File permissions: system groups for do not work for group/shared mailboxes
by Jens Kirchner 08 Sep '15

08 Sep '15

Hello! I am struggling to set up a group mailbox for users of a certain system group. I want to grant access to the mailbox on a filesystem mode by using the system groups. The problem, the set up works fine and when I use setfacl and grant permissions too each user manually, it works fine. However, I want to use a system user's group membership in order to grant access to these mailboxes insted of manually granting for each user. dovecot version: 2.2.9 This is the config part: namespace { location = maildir:/data/mail/public:LAYOUT=fs prefix = GROUP-MAILBOXES/ separator = / subscriptions = no type = public } ... passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } ... userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } filesystem permissions (getfacl): # file: GroupboxA/ # owner: root # group: root user::rwx user:user1:rwx group::rwx mask::rwx other::--- default:user::rwx default:user:user1:rwx default:group::rwx default:mask::rwx default:other::--- # file: GroupboxB/ # owner: root # group: root user::rwx group::rwx group:group1:rwx mask::rwx other::--- default:user::rwx default:group::rwx default:group:group1:rwx default:mask::rwx default:other::--- user1 is in roup1 When setting username-based permissions (GroupboxA), the mailbox is usable and subsribable; when setting groupname-based permissions (GroupboxB) it is not subscribable/usable. Thanks for your help in advance and best regards, Jens

bug in acl_defaults_from_inbox option
by Marco Giunta 08 Sep '15

08 Sep '15

Hi at all, there is a bug in in acl_defaults_from_inbox option: if you define it with ANY value ('yes', 'no', 'whatyouwant', 'xxx') it acts like the value is ALWAYS 'yes', and Dovecot enable it; the only way to disable it, is comment it or delete from configuration file. With 'acl_defaults_from_inbox = no', or 'acl_defaults_from_inbox = whatyouwant', all my folders get ACLs from INBOX; in my case I want to only share INBOX, but also all other folders were shared. When you comment 'acl_defaults_from_inbox', Dovecot works like expected.

Patch for "doveadm -f table" nit (was Re: Dovecot current number of connections being used.)
by Joseph Tam 07 Sep '15

07 Sep '15

> doveadm who -1 2>/dev/null | wc -l You have to redirect stderr to /dev/null because that's where the first header line is written to. The default format style (table) is inconsistent with the other formats (flow,pager,tab) that write headers and data to stdout. The following patch will pick this nit. This patch will require modifications to scripts that rely on doveadm writing headers to stderr. For example, the above doveadm command could be modified to doveadm who -1 | grep -vc '^username' -------------------------------------------------------------------------------- --- a/dovecot-2.2.16.rc1/src/doveadm/doveadm-print-table.c Wed Mar 18 15:40:40 2015 +++ b/dovecot-2.2.16.rc1/src/doveadm/doveadm-print-table.c Wed Mar 18 15:41:18 2015 @@ -151,3 +151,3 @@ for (i = 0; i < count; i++) { - if (i > 0) fprintf(stderr, " "); + if (i > 0) printf(" "); @@ -155,3 +155,3 @@ DOVEADM_PRINT_HEADER_FLAG_RIGHT_JUSTIFY) == 0) { - fprintf(stderr, "%-*s", (int)headers[i].length, + printf("%-*s", (int)headers[i].length, headers[i].title); @@ -158,3 +158,3 @@ } else { - fprintf(stderr, "%*s", (int)headers[i].length, + printf("%*s", (int)headers[i].length, headers[i].title); @@ -162,3 +162,3 @@ } - fprintf(stderr, "\n"); + printf("\n"); } -------------------------------------------------------------------------------- Joseph Tam <jtam.home(a)gmail.com>

Re: Null deference pointer in dovecot-2.2.18
by 吴迪 07 Sep '15

07 Sep '15

Dear, use our static analysis tools, I find some bugs (Null deference pointer) for dovecot-2.2.18. Null deference pointer bugs often make program crashes, Please confim them, Thanks! 1. dovecot-2.2.18/src/config/config-request.c 332 'setting_export_section_name(ctx->prefix, def, children[i], i);', pointer 'children' in line 202 assigned NULL and if branch 'case SET_DEFLIST_UNIQUE' not execute, so pointer 'children' is always NULL. It load to a bug of null deference pointer In line 332. The same bugs also appeared in : 1. dovecot-2.2.18/src/lib-index/mail-index-fsck.c line 170 or 174, pointer 'kw_rec ' mybe NULL. 2.dovecot-2.2.18/src/lib-storage/mail-search-args-simplify line 349, pointer 'prev_arg' mybe NULL. best wishes~ Amy

RFC 5465 (NOTIFY) violation: missing HIGHESTMODSEQ in initial STATUS responses
by Guilhem Moulin 07 Sep '15

07 Sep '15

Quoting RFC 5465 (NOTIFY): “If the NOTIFY command enables MessageNew, MessageExpunge, AnnotationChange, or FlagChange notifications for a mailbox other than the currently selected mailbox, and the client has specified the STATUS indicator parameter, then the server MUST send a STATUS response for that mailbox before NOTIFY's tagged OK. […] If either AnnotationChange or FlagChange are included and the server also supports the CONDSTORE [RFC4551] and/or QRESYNC [RFC5162] extensions, the STATUS response MUST contain UIDVALIDITY and HIGHESTMODSEQ.” — https://tools.ietf.org/html/rfc5465#section-3.1 While unsolicited STATUS responses include HIGHESTMODSEQ indeed, the initial STATUS responses (caused by the presence of the STATUS indicator) do not: ~$ /usr/lib/dovecot/imap * PREAUTH [CAPABILITY IMAP4rev1 … CONDSTORE QRESYNC … NOTIFY SPECIAL-USE] Logged in as guilhem a ENABLE QRESYNC * ENABLED QRESYNC a OK Enabled (0.000 secs). b NOTIFY SET STATUS (SUBSCRIBED (MessageNew MessageExpunge FlagChange)) * STATUS INBOX (MESSAGES 9069 UIDNEXT 109398 UIDVALIDITY 1312585007 UNSEEN 0) […] b OK NOTIFY completed (0.008 secs). [time passes… a new message is delivered to INBOX] * STATUS INBOX (MESSAGES 9070 UIDNEXT 109399 UNSEEN 1 HIGHESTMODSEQ 22216) This defeats the purpose of the STATUS indicator for disconnected clients since they have to issue separate STATUS commands (or a LIST command if LIST-{EXTENDED,STATUS} have been advertized) to find out which mailboxes have got a new HIGHESTMODSEQ. Cheers, -- Guilhem.

Here is an example with APPEND $ /usr/lib/dovecot/imap S1: * PREAUTH [CAPABILITY IMAP4rev1 … MOVE NOTIFY SPECIAL-USE] Logged in as guilhem C1: a1 NOTIFY SET (INBOXES (MessageNew MessageExpunge FlagChange)) S1: a1 OK NOTIFY completed (0.000 secs) $ /usr/lib/dovecot/imap S2: * PREAUTH [CAPABILITY IMAP4rev1 … MOVE NOTIFY SPECIAL-USE] Logged in as guilhem C2: a2 APPEND INBOX {1+} C2: x S2: a2 OK [APPENDUID 1384472528 26085] Append completed (0.229 secs). With 2.13 from Debian Jessie, S1 sends a notification for the new message in INBOX, as expected: S1: * STATUS INBOX (MESSAGES 4333 UIDNEXT 26086 UNSEEN 1) However it doesn't with 2.18 from Debian Sid, as if ‘INBOX’ was excluded from the mailbox filter ‘INBOXES’. It does send a notification for ‘virtual/unseen’ instead (as expected), but nothing for ‘INBOX’. S1: * STATUS virtual/unseen (MESSAGES 3 UIDNEXT 15186 UNSEEN 3) This is INBOX-specific because APPENDING the message to another mailbox triggers the notification on both 2.13 and 2.18 as expected: S1: * STATUS test (MESSAGES 2 UIDNEXT 3 UNSEEN 2) S1: * STATUS virtual/unseen (MESSAGES 2 UIDNEXT 15195 UNSEEN 2) I attach the ‘dovecot -n’ output for both 2.13 and 2.18. -- Guilhem.

"NOTIFY SET (mailboxes INBOX (...))" crashes the IMAP client

Hi list, The NOTIFY extension (RFC 5465) works fine for mailboxes in the "virtual/" namespace, but it crashes the IMAP client when used with a mailbox in the empty "" namespace: ~$ /usr/lib/dovecot/imap * PREAUTH [CAPABILITY IMAP4rev1 … NOTIFY SPECIAL-USE] Logged in as guilhem a NAMESPACE * NAMESPACE (("" "/")("virtual/" "/")) NIL NIL a OK Namespace completed. b NOTIFY SET (mailboxes virtual/all (MessageNew MessageExpunge)) b OK NOTIFY completed (0.001 secs). c NOTIFY SET (mailboxes INBOX (MessageNew MessageExpunge)) imap(guilhem): Panic: file mail-namespace.c: line 679 (mail_namespace_find): assertion failed: (ns != NULL) imap(guilhem): Error: Raw backtrace: … Aborted The "subtree" mailbox filter has the same problem, but the non-parameterized ones ("inboxes", "personal" and "subscribed") work fine.

question on autch cache parameters
by matthias lay 07 Sep '15

07 Sep '15

Hi list, I have a question on auth caching in 2.2.18. I am using acl_groups for a master user, appended in a static userdb file # snip ############################### master@uma:{SHA}XXXX=::::::userdb_acl_groups=umareadmaster allow_nets=127.0.0.1 # snap ############################### and use this group in a global ACL file. I discovered this only works on first NOT-cached login environment in imap-postlogin script on first login: AUTH_TOKEN=e96b5a32ceb2cafc4460c210ad2e92e3d7ab388c MASTER_USER=master@uma SPUSER=private/pdf LOCAL_IP=127.0.0.1 USER=pdf AUTH_USER=master@uma PWD=/var/run/dovecot USERDB_KEYS=ACL_GROUPS HOME SPUSER MASTER_USER AUTH_TOKEN AUTH_USER SHLVL=1 HOME=/var/data/vmail/private/pdf ACL_GROUPS=umareadmaster IP=127.0.0.1 _=/usr/bin/env on the second cached login it looks like this AUTH_TOKEN=12703b11932f233520f6d4b33559c33aeb1cfc7f MASTER_USER=master@uma SPUSER=private/pdf LOCAL_IP=127.0.0.1 USER=pdf AUTH_USER=master@uma PWD=/var/run/dovecot USERDB_KEYS=HOME SPUSER MASTER_USER AUTH_TOKEN AUTH_USER SHLVL=1 HOME=/var/data/vmail/private/pdf IP=127.0.0.1 _=/usr/bin/env so the ACL_GROUPS is gone. is this intended to be like that. so groups not included in cache and I have to find another approach? anybody else encountered similar problems with some auth Variables and caching?

doveadm quota recalc problem for domain
by Samuel 06 Sep '15

06 Sep '15

Hello, I've set up user quota and domain quota for dict SQL and all seems OK. New mail for user increase the user quota and the domain quota. Deleting email count down user quota and domain quota. But in case of SQL failure, I'm trying to rebuild the user quota and domain quota with doveadm quota recalc. The problem is that the command : 'doveadm quota recalc -u foo@bar' sets the domain quota only with user foo@bar even when I try a domain quota recalc : doveadm quota recalc -A or doveadm quota recalc -u *@bar (only one user is taken in account for the domain quota and not all the user). The domain SQL database is broken with value of only one user for the whole domain quota. So how to achieve rebuild domain quota correctly with doveadm ? Thanks a lot. Samuel.

Mailbox can't be created

Hi, I have setup postfix master.cf to use dovecot-lda to deliver (using -m) all messages to PreInbox: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -f ${sender} -a ${recipient} -d ${user}@${nexthop} -m PreINBOX And enabled lda_mailbox_autocreate.

Considerations for a not so simple set-up ...
by Lars Hanke 05 Sep '15

05 Sep '15

I want to set up a new IMAP server with Dovecot, so far I've been running Cyrus. I'm running dovecot on Debian Jessie. The general idea of the system would be: 1) Virtual users, i.e. login users are disjoint from any mail accounts. 2) Real-Users authenticate using their kerberos tickets. 3) There is a n-to-n mapping of real to virtual users. 4) Maildirs shall be stored on glusterfs. 5) Fallback passwords for cloud access Concerning 1) and 2) I keep reading that this is possible, but I could not find any concise and current description. I'd welcome pointers to howtos. Concerning 3) this should be a matter of ACL, e.g. a single real user (kerberos pricipal) may have several mail-boxes (virtual users), and groups of real users may share the same mail-box. I have a faint idea, how this could be done in Cyrus (but never did that), but I read that these features should exist in Dovecot as well. But I'm completely lost to even figure out a starting point. I appreciate any keywords for further reading. Concerning 4) I read that there are some issues using NFS. Are there any caveats when using gluster? Concerning 5) Users logging in from outside may not have TGT on their notebooks, which by design should run as stand-alone. They should nevertheless be able to access their mail. I currently think of another set of real users, but anything less messy is welcome. Did someone try something similar, already? Thanks for your help, - lars.

'doveadm expunge' with -A and userdb { driver = passwd }
by Grant 04 Sep '15

04 Sep '15

I'm expunging mail in my crontab like this: doveadm search -u user1 mailbox INBOX.Trash savedbefore 30d doveadm search -u user2 mailbox INBOX.Trash savedbefore 30d doveadm search -u user3 mailbox INBOX.Trash savedbefore 30d ... I'd rather do this: doveadm search -A mailbox INBOX.Trash savedbefore 30d but I'm told not to: "If the -A option is present, the command will be performed for all users. Using this option in combination with system users from userdb { driver = passwd } is not recommended, because it contains also users with a lower UID than the one configured with the first_valid_uid setting." I'm using userdb { driver = passwd-file } but I'm guessing that's the same thing. Am I understanding this correctly? - Grant

apple mail fails to connect intermittently
by Eric Smith 04 Sep '15

04 Sep '15

Hi (New to dovecot) I am experiencing intermittent connection failures with both apple mail and ios mail. No specific errors and I cannot find relevant information on the mac logs or on my server. It spontaneously corrects. restarting dovecot - no dice It just happened now (again), this time there might have been a reason, I just dovecot-lda'd some large mailboxes from mbox to Maildir. But as I said, it spontaneously corrects, so is downloading now. While this connection error is occurring, then I can connect to dovecot via a remote mutt session, via web imap client and via outlook. Is this a known issue? FWIW: % doveconf -n # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.19.0-26-generic i686 Ubuntu 15.04 lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } mailbox virtual/All { special_use = \All } prefix = } passdb { driver = pam } postmaster_address = postmaster(a)biovolt.nl protocols = " imap lmtp" ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = passwd } protocol lda { info_log_path = /tmp/dovecot-deliver.log log_path = /tmp/dovecot-deliver-errors.log } Thanks Eric

Reviving an old thread: "requiring client certificates for external connections"
by Robert Giles 03 Sep '15

03 Sep '15

Hi folks - reviving an old thread from 2010: http://www.dovecot.org/list/dovecot/2010-December/055837.html We're basically looking to do the same thing: require client certificates for external connections, while preserving certificate-less username/password authentication for internal connections. Any tips on the best way to accomplish this? 'ssl_verify_client_cert = yes' can go within a local {} block, but it doesn't seem to force the client to submit a certificate. Thanks in advance - Robert Giles

new server
by Franc 03 Sep '15

03 Sep '15

I am going to build a new box (2-3.000 users, 4-500 domains name (50-100 real, remaining used as redirect on the main (.it,.eu,.com,...)) . Is there any how-to or similar to follow for build an updated system? (My current boxes are based on CentoOS 6.x using included Dovecot + PostFix .rpms) I am thinking to CentOS 7.x + Dovecot + PostFix + RoundCube + Squirrel + procmail with unix users and virtual users. But I admit that systemd isn't still my best friend ... :-) In CentOS 7.x there is a default dovecot-2.2.10. Is it enough Ok or better use different rpms source? Any hints is welcomed :-) Thanks, F.

sieve filtering utf 8 strings
by Sergey Schwartz 03 Sep '15

03 Sep '15

Guys, I'm completely stuck, so asking for advice. My user has a sieve script which checks message header if it contains words in russian like 'Лист бронирования отправлен'. Pritty simple script # rule:[Отправлено] if allof (header :contains "subject" "LDS (robot): Лист бронирования отправлен", header :contains "from" "noreply(a)bgoperator.com") { fileinto "Отправлено"; } I don't have errors compiling the script or executing it via LMTP, but it doesn't work. Normally user receives messages from robot with subject encoded as quoted-printable Subject: =?UTF-8?Q?LDS_(robot):_=D0=9B=D0=B8=D1=81=D1=82?= =?UTF-8?Q?_=D0=B1=D1=80=D0=BE=D0=BD=D0=B8=D1=80=D0=BE=D0=B2=D0=B0=D0=BD?= =?UTF-8?Q?=D0=B8=D1=8F__=D0=BE=D1=82=D0=BF=D1=80=D0=B0=D0=B2=D0=BB=D0=B5?= When I send a test message via Thunderbird with required words - sieve works fine and subject is encoded in base64 Subject: =?UTF-8?B?0JvQuNGB0YIg0LHRgNC+0L3QuNGA0L7QstCw0L3QuNGPINC+0YLQv9GA?= =?UTF-8?B?0LDQstC70LXQvQ==?= It is the same text, but encodind is different - base 64 works fine and quoted-printable does not. Is it possible to have both supported for sieve ? -- Best regards, Sergey Schwartz Senior System Administrator Biblio Globus Tour Operator www.bgoperator.ru T: +7 495 5042500 ext 1532 E: sergey.schwartz(a)bgoperator.com

Where Dovecot stores the information, that I had unsubscribed from this folder? I need this to analyze subscriptions over all mail acounts. Thank you, Miloslav

more than two way replication
by djk 02 Sep '15

02 Sep '15

Is there anyway of replicating between more than one other instance of Dovecot. I have bidirectional replication working successfully and it seems to be reliable. I would like to replicate from one or more of these instances to one other. Is this possible? Dirk

imap segfaults when using antispam plugin, and moving mail to an 'unsure' folder.
by Andrew McN 02 Sep '15

02 Sep '15

I put up a question on serverfault first, which has the details, including a stack trace: http://serverfault.com/questions/713687/dovecot-antispam-error-storing-mail . Details also copied below. Is this a known bug? If I built dovecot from source rather than using the Ubuntu 14.04 packages, would I expect that to help? Are there any configuration details that might be relevant? (dovecot -n output shown Any help much appreciated. Andrew McNaughton Details on the serverfault page repeated below, plus a little more. ----------------------------------------------------- Ubuntu 14.04.3 x86_64 Running inside lxc-docker 1.7.0 dovecot-imapd 1:2.2.9-1ubuntu2 dovecot-antispam 2.0+20130822-2build1 Filesystem is via docker, so aufs is involved, and under that on the host systems is ext4 ----------------------------------------------------- I know mail is not supposed to be moved into a mailbox of type 'unsure'.

doveadm-server hangs with 100% cpu usage
by Dennis Kuhn 02 Sep '15

02 Sep '15

we have some replication issues. From time to time a doveadm-server process takes 100% cpu in the state recv_mailbox_tree_deletes on the replica. The process runs forever until it is manually killed. Strace on this process doesn't show anything. Sometimes we have several doveadm-server processes in this state, all for the same account, all with 100% CPU Load. The logfile on the master says: Error: Timeout during state=recv_mailbox_tree Error: dsync(dobby5.heinlein-support.de): I/O has stalled, no activity for 600 seconds My workaround is to delete the user directory on the replica so that the whole account is replicated again. This solves the problem for this specific account. The dovecot version is 2.2.15 on the master and 2.2.16 on the replica.

Moving mails from shared folder to shared folder doesn't work
by Peer Heinlein 02 Sep '15

02 Sep '15

Hi, having the attached configuration with Dovecot 2.2.9, Dovecot's crashing when moving a mail from a shared folder into another shared folder. Moving that mail into a "real" folder of the user or moving that mail from a real folder into the shared folder is always working. But moving from a shared folder into a shared folder doesn't work.

Single Instance Storage after the fact
by Joe Beaubien 02 Sep '15

02 Sep '15

Hi everyone, I tried to find info about this online, but I couldn't find anything talking specifically about what I am trying to accomplish. I am sending and receiving the same attachments pretty often and as a result my email accounts are growing much more rapidly than I would like. *My goal* is to set up a second instance of Dovecot with SIS enabled and transfer everything over to this new Dovecot setup. I was thinking of simply running a dsync backup from the old instance and then a dsync backup -R on the new instance with SIS. Would this effectively create a new set of mailboxes without attachments (and a new folder full of attachments)? If not, can someone point me to information on how to accomplish this? Best regards, Joe B.

Post-migration questions
by Grant 29 Aug '15

29 Aug '15

I just migrated from courier-imap to dovecot and dovecot is a lot faster. My only client is webmail on the same server as dovecot. Max ~10 users. Should I still run imapproxy like I did with courier? Does dovecot periodically empty the trash folder like courier does? I reduced the number of processes courier was running to save RAM and improve performance. Are there any performance tweaks I should consider for dovecot? - Grant

IMAP hibernate feature committed
by Timo Sirainen 29 Aug '15

29 Aug '15

http://hg.dovecot.org/dovecot-2.2/rev/64c73e6bd397 Today I finally committed the "imap-hibernate" feature that I first started developing about a year ago (and had been thinking about for several years before that). The main purpose here is to reduce the number of imap processes and the amount of memory they use by moving IDLEing connections into imap-hibernate processes where they are waiting for something to happen (changes to the mailbox or IMAP client to do something). Mailbox changes are noticed only if inotify/kqueue is enabled, so without them the hibernation feature won't work well. For now only the IMAP connections that are in IDLE can be hibernated. In theory non-IDLEing connections could also be hibernated, but the main problem here is that if EXPUNGEs can't be sent at the time the hibernation is over, the current code can't handle it. They would require recreating a view that contains such expunged messages, which could be possible with some extra work. Some IMAP extensions aren't supported yet: - NOTIFY: This would just need to import/export the NOTIFY state. Also hibernation could be done at any time if VANISHED replies could be sent to the selected mailbox. - SEARCH=CONTEXT: A bit more troublesome extension to support. I'm not sure how big the trouble would be. It's rarely used though. - COMPRESS: The [de]compression code would need to be moved to login process instead of being done in imap-compress plugin. This would be a larger change, although it's also useful for various other purposes. The hibernation can be enabled for now simply by setting imap_hibernate_timeout setting to non-zero, which controls how long to wait after client has issued IDLE (and nothing happens) until the process hibernates. Some future work might include: - Moving the hibernation all the way to the first Dovecot proxy layer to avoid the need for imap-hibernate process at all. (Also moving the COMPRESS handling all the way there.) - Dynamically adjusting when the client should be hibernated instead of just a fixed imap_hibernate_timeout setting. Especially try to avoid such a situation where the hibernation is almost always terminated soon after it started. Although that probably is unlikely, so maybe not worth the trouble to prevent.. - Hibernation could be used to control the load of the server. If it's running too slow or if there are already too many imap processes, some of the connections could be moved to hibernation stage. Or just kept in hibernation for a while longer even after the imap process would normally be recreated (e.g. wait for several minutes before reporting new emails, or several seconds before replying to DONE). - The EXPUNGE/VANISHED and FETCH FLAGS replies aren't sent asynchronously, but instead fully buffered to the output buffer. This works as long as the list of changes after hibernation isn't huge, but otherwise it's wasting a lot of memory. - Maybe support non-inotify/kqueue change notifications from lib-storage. This could be complicated though to do efficiently. Or a simple way would be to just send a UDP or UNIX datagram packet on all changes to all the imap-hibernate processes and see if anybody cares about those. I'm not sure how efficient that would be.

Dovecot proxy and password scheme updating
by efs efefsfse 28 Aug '15

28 Aug '15

Hello, I run a dovecot proxy (which is doing authentification itself) and a dovecot backend on separate boxes. I want to change the actual password scheme. Since postlogin scripting is not supported by proxies and %w variable is not forwaded to dovecot backend is there any way that I can update the password scheme with my current setup ? Thanks in advance.

Allow delivery to existing accounts only with LDAP and static
by Miloslav Hůla 28 Aug '15

28 Aug '15

Hi, we are using LDAP binding as a passdb, and static with allow_all_users=yes as an userdb. Works fine, but problem is, Maildirs are created for non-existent accounts too. We would like to prevent it. The LDAP binding does not supporta user lookups. Is the correct way to use checkpassword as a passdb before LDAP, check for account existency here and: result_success=continue result_failure=return-fail ? Thank you, regards, Miloslav

Merging maildirs
by Petter Gunnerud 28 Aug '15

28 Aug '15

Hi List How do I merge files from one maildir into another maildir? Long version: I've been using dovecot/postfix for a 12 user environment for several years, and today was the first time I ran into an issue I could not solve from reading the documentation. The server is gentoo running on esxi. A few times a year I've made a snapshot of the server and copied the files to my home esxi server as a full system backup. 5 days ago the internet connection at the office broke, and I decided to power on the last copy of the server at my home and change public dns so that users could access their new mails via webmail from this spare server. (I didn't allow imap through firewall.) Now the network at the office is back. DNS is updated so that mails are delivered to the office server again. But all the mails sent / received during those 5 days is only at my house. How can I merge those into the office server?I'd like to do this as a server administrator. I do not want to have each user forward the mails to them self from the temporarily webmail. I tried to just copy the mail files on my own account - like I did once when I used courier-imap, but that did not work with dovecot. I hope someone has an idea of how to solve this.

Duplicate folder names
by Paulo Matos 26 Aug '15

26 Aug '15

Hi, I have setup message filtering and for example, I might move a message which a given sender to folder special/. This folder is created and shows up twice in INBOX/special/ and special/. They are however exactly the same folder. If I subscribe to one I am automatically subscribed to the other and viceversa. Not too happy with this configuration. I have a feeling this is related to namespaces but I am not sure in which way to configure things in order to have only INBOX/special but not special/. How can I set this up. My current configuration is: $ dovecot -n # 2.2.18: /etc/dovecot/dovecot.conf # OS: Linux 4.1.0-x86_64-linode59 x86_64 Fedora release 22 (Twenty Two) ext4 auth_debug = yes auth_mechanisms = plain login digest-md5 cram-md5 auth_verbose = yes auth_verbose_passwords = yes default_internal_user = root imap_client_workarounds = delay-newmail tb-extra-mailbox-sep mail_debug = yes mail_location = maildir:/home/vmail/%d/%n/Maildir maildir_very_dirty_syncs = yes mbox_write_locks = fcntl namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace inbox { location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } postmaster_address = pmatos protocols = imap quota_full_tempfail = yes service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-master { mode = 0600 user = vmail } user = $default_internal_user } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes driver = static } protocol lda { auth_socket_path = /var/run/dovecot/auth-master deliver_log_format = msgid=%m: %$ log_path = /home/vmail/dovecot-deliver.log } protocol imap { mail_max_userip_connections = 100 } Regards, Paulo Matos

Store ACL files within shared mailbox / rename shared folder problem
by Chris Laif 24 Aug '15

24 Aug '15

Hi. If $otheruser shares a mailbox to $myuser, my private index is stored in *my* Maildir, according to this template (from the dovecot docs): mail_location = maildir:%%h/Maildir:INDEXPVT=%h/Maildir/shared/%%u If $otheruser renames the shared mailbox, all my private mail flags (Seen) are lost because my mailclient couldn't find the private index anymore. Is there any way to store the private index within the shared mailbox? If $otheruser renames the mailbox, the index will be 'migrated' as well. Something like this: /data/mails/$otheruser/Maildir/.MagicSharedFolder/shared/$myuser.dovecot.index.pvt.log I see no way on how to do craft a INDEXPVT for this. Kind regards, Chris

Hello ! I've installed iRedMail on an Ubuntu Server 14.04.1 I'm not the only one on the iRedMail forum to have the problem, but the developpers of iRedMail doesn't found the problem and advice me to ask you directly.

IMAP Folder Mail Separator
by Alex 23 Aug '15

23 Aug '15

Hi, I have a fedora21 install with dovecot-2.2.18, and when creating a new subfolder with thunderbird, the actual folder name is "Folder1^Folder2" with a carat as a separator, instead of creating Folder2 in the Folder1 directory. Is this a thunderbird problem? I don't recall having this problem prior to upgrading to fedora21, so thought maybe it's a dovecot problem. Maybe the separator character is customizable? Thanks, Alex

migrating servers
by chris 23 Aug '15

23 Aug '15

Hi I am trying to migrate from a Centos dovecot 1.0.7 install to a debian dovecot 2.1.7 install. I thought simply replicating the maildirs would be fine (using rsync) but when I fetch mail from the new server using IMAP thunderbird wants to download all the messages again as duplicates. I searched the wiki over to see if I could find a solution and while it appeared I could use doveadm backup that seems to only work pushing changes from the new server to the old (wrong direction) and that program does not exist on the earlier version of dovecot on the old server. If I can be very blunt the documentation on the wiki assumes far too much knowledge from the reader. It is often hard to decipher exactly what is meant by many of the obtuse instructions. But that is an aside can anyone give me pointers on how to do this migration for all my users so they don't need to sort through hundreds of duplicated emails? Chris

OK, I obviously forgot something when setting up new user accounts (which I did via postfix admin to add them to the MySQL database): dovecot: lda(chance(a)example.com): Error: User initialization failed: Namespace '': Ambiguous mail location setting, don't know what to do with it: /usr/local/virtual/chance@ example.com (try prefixing it with mbox: or milder:) I have lots of mysql users defined and working, but do I need to manually create the mail store for new ones?

logging into user mailboxes with admin credentials
by Noam Birnbaum 19 Aug '15

19 Aug '15

Hey folks, We are planning a migration away from Dovecot (sorry) to Google Apps and are trying to figure out how to migrate the contents of user mailboxes to the new provider. Normally we would use an IMAP migration tool to log into each user's mailbox on the old and new providers and transfer the data that way. However, there is no central directory service; all accounts are local. We have a large number of users and for both management and security reasons it's not feasible to compile a list of all IMAP passwords. Is there a way to log into user IMAP accounts on Dovecot using a central administrative credential? Thanks!

NFSv4 delegation
by brd 18 Aug '15

18 Aug '15

hi all, i'm managing a large installation of a dovecot cluster in director + NFS backend architecture and we are moving from NFSv3 to NFSv4. Our NFS server is a Netapp in clustered mode and reading technical specs of NFSv4 delegation feature it seems that enabling delegation in this type of dovecot architecture should bring great benefits: only one backend server access a specific mailbox at a time (even deliveries are managed by director hashing via LMTP) so the getattr rpc calls should decrease significantly while the risk of conflicting delegations is very low (impacting negatively on the benefits obtainable). Can anyone confirm this hypothesis? I've heard that the linux implementation of NFSv4 delegation is mature only for read delegation (and not yet for write delegation): is this true? And, if true, could this fact limit the benefits of activating NFS delegation feature? Best regards -brd

multiple messages per second to a single mailbox
by Chad M Stewart 18 Aug '15

18 Aug '15

Dovecot 2.2.18 on CentOS 6 I have a pair of servers setup with MySQL, Postfix, and Dovecot. Replication is setup and working between the two dovecot instances. The problem I'm running into is that a single mailbox receives a lot of messages, at times the rate is multiple messages per second. Delivery from Postfix to Dovecot is via tcp based LMTP. When I do 'ps -aef|grep lmtp|wc -l' I get 62 and does not appear to go higher than that. At the moment I have 4500 and 8300 messages queued on two Postfix instances waiting to deliver via LMTP to the same dovecot instance. Deliveries only happen via LMTP and only one of the two nodes actually gets the deliveries. What I'm seeing is very high load on the system (40) and queues building on the Postfix side. Replication is keeping up. Looking at the logs now I see anywhere from 4-7 messages per second delivered to this single mailbox. I would like to increase that rate a lot. These machines are VMs hosted on Xenserver 6.x. I have them setup with 8 vCPUs (2 sockets with 4 cores per socket), the dom0 machines have dual HBA connectors back to a SAN and have 128 CPUs and 256GB of RAM and are not taxed. I added a 2nd virtual disk that is used for storing mailbox data. It is ext4 and has noatime set during mount. /var is also mounted with noatime. The performance graphs in XenCenter show nearly all 8 vCPUs at about 50%, and the writes on the mailbox data disk are about 20%. iostat is showing mostly <5 for await times for the disks, though I do see a 10 now and again. I'm guessing that maybe I'm hitting a mailbox locking issue and not sure how to reduce the contention and thereby increase the delivery rate to this mailbox. -Chad

Syncing two mail servers?
by Knute Johnson 17 Aug '15

17 Aug '15

I currently have a mail server using Dovecot and sendmail. I was thinking I would like to have a backup of my mail and an additional server in case of hardware failure. Is it possible to run two identical or nearly identical server setups and sync the mail files between them? If it is possible, in general terms how would one go about this? Thanks, -- Knute Johnson

sieve-filter failure problems
by Jost Krieger 17 Aug '15

17 Aug '15

I use sieve-filter for postprocessing misclassified mail. For false positives I use the following script: require [ "variables", "include", "fileinto" ]; global [ "FORCENOSPAM", "ext", "ext1" ]; set "FORCENOSPAM" "YES"; fileinto "JUNK-PRENOUCE"; if header :matches "Delivered-To" "*+*@*" { set "ext" "${2}"; set "ext1" "${2}"; } include :personal "production"; FORCENOSPAM suppresses the spam handling and the Delivered-To stuff tries to regenerate envelope info. This is my crontab entry: 1-57/4 * * * * cd ~kriegjcb; /usr/local/dovecot/bin/sieve-filter -v -e -W -u kriegjcb -m Spam/U0-failed ~kriegjcb/sieve/nospamfilter.sieve Spam/U0 Most things work fine, but a few of my rules will try to forward mail. This will fail and my idea was I handle this manually from the folder Spam/U0-failed. Unfortunately the mail will arrive there but will also be left in the source folder Spam/U0 and will be processed again every 4 minutes ... This is probably not intentional?

Duplicate mails with pop3 + dsync replication
by Wolfgang Hennerbichler 17 Aug '15

17 Aug '15

Hi, When I enable (and it only happens when it is actually running) replication over TCP my users get duplicate mails via pop3. Here’s what happens: * User gets mail * Mail appears in (Maildir) new/ folder on both replicas * user retrieves mail (retr), calls dele. Mail still exists in new/ folder on both replicas. * user runs retr (and gets the duplicate) and dele a second time, the mail is actually removed. If I disable replication this behaviour goes away. I use dovecot from debian stable resources. Any help would _really_ be appreciated. I found one german thread that dealt with the same problem, but no solution for it (http://www.dovecot-buch.de/mailingliste/pop3-fehler-bei-delete-und-dsync-re…) wogri # dovecot --version 2.2.13 # dovecot -n # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 3.16.0-4-amd64 x86_64 Debian 8.0 ext4 auth_verbose = yes doveadm_password = XXX first_valid_gid = 113 first_valid_uid = 108 last_valid_gid = 113 last_valid_uid = 108 mail_gid = dovecot mail_location = maildir:/var/mail/%n mail_plugins = quota fts fts_lucene virtual notify replication mail_temp_dir = /var/lib/dovecot/tmp mail_uid = dovecot namespace { list = children location = virtual:/var/mail/%n/virtual prefix = virtual. separator = . } namespace inbox { inbox = yes list = yes location = mailbox "Deleted Messages" { auto = subscribe special_use = \Trash } mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { auto = no special_use = \Sent } mailbox Spam { auto = subscribe special_use = \Junk } [48/4646] mailbox Trash { special_use = \Trash } prefix = separator = . subscriptions = yes type = private } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { default_language = de fts = lucene fts_lucene = whitespace_chars=@. mail_replica = tcp:172.16.1.1:12345 quota = maildir:User quota quota_rule = *:storage=4G quota_rule2 = Trash:storage=+100M quota_rule3 = Spam:ignore quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u sieve = /etc/sieve/%n.sieve sieve_default = /etc/sieve/default.sieve sieve_dir = ~/sieve sieve_extensions = +editheader } postmaster_address = postmaster(a)wogri.at protocols = " imap lmtp pop3" service aggregator { fifo_listener replication-notify-fifo { user = dovecot } unix_listener replication-notify { user = dovecot } } service doveadm { inet_listener { port = 12345 } } service imap { process_limit = 1024 } } service lmtp { inet_listener lmtp { address = 127.0.0.1 port = 2003 } user = dovecot } service managesieve-login { inet_listener sieve { port = 4190 } service_count = 1 } service pop3 { process_limit = 1024 } service quota-warning { executable = script /usr/local/sbin/quota-warning.sh unix_listener quota-warning { user = dovecot } user = dovecot } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0600 } } ssl = required ssl_cert = </etc/exim4/server.cert.pem ssl_key = </etc/exim4/server.key.pem userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { mail_plugins = quota sieve virtual notify replication } protocol lda { mail_plugins = quota fts fts_lucene virtual notify replication sieve } protocol imap { mail_max_userip_connections = 50 mail_plugins = quota fts fts_lucene virtual notify replication imap_quota }

sieve and antispam
by Andrew McN 17 Aug '15

17 Aug '15

I have a fairly standard antispam/dspam setup: postfix delivers to dspam, which classifies and tags the mail, and then passes it to postfix which uses sieve to put mail into the appropriate folders based on dspam's classification. I also have the antispam plugin watching mail being moved between folders and re-training dpsam accordingly. If I now add some sieve filter rules which put incoming mail into appropriate folders, possibly overriding what would normally result from dspam's classification, will that be seen by the antispam plugin and used for training dspam?

ipv4 imap not accepting connections in mixed ipv4/ipv6
by djk 15 Aug '15

15 Aug '15

I have two installations of dovecot 2.18, apart from the necessary changes to allow them to replicate amongst themselves the configs are identical. Both are running Ubuntu 14.04 and are kept up to date. One is running 64bit and the other 32 bit (for historical reasons). Both have ipv4 and ipv6 addresses. The 64 bit installation allows access on port 143 and 993 on both ipv4 and ipv6. The 32 bit installation does not allow access on 143 on ipv4, but allows ipv4/ipv6 on 993. Both installations happily allow connections to any other ports that dovecot might be using on both ipv4/ipv6, as well as everything else that is running (on other ports) on those machines. There are firewalls, but no warning messages. Switching firewalls off makes no difference. Tcpdump shows the SYN packets arriving on the (correct) interface. Any suggestions? Dirk

IMAP folder separator issue
by Alex 15 Aug '15

15 Aug '15

Hi, I'm using dovecot-2.2.18 on fedora22 and having a problem with Thunderbird. I reported this problem some time ago, and received some tips, but no solution that's worked. I'm now trying to fix this in earnest, and having problems. The problem is sub-folders are created with a caret in them, instead of a new folder below the parent folder. So instead of folder/sub-folder, folder^sub-folder is created. I'm using mbox folders, and it worked under previous versions of fedora and dovecot. I believe it has to do with the separator character that's used, based on this wiki page: http://wiki2.dovecot.org/Plugins/Listescape The problem is that those instructions cause errors: Aug 14 20:00:01 orion dovecot: pop3(cerberus): Error: User initialization failed: namespace configuration error: Duplicate namespace prefix: "" Aug 14 20:00:01 orion dovecot: pop3(cerberus): Error: Invalid user settings. Refer to server log for more information. I've also had to change the "namespace private" to "namespace { type=private }" as that's apparently a deprecated syntax. Perhaps there's an updated page with more instruction and correct information? I'm unsure where this duplicate namespace is that it's talking about... I've included my doveconf output below, in hopes someone can help. I should also point out that "separator = $" is quoted in the original doveconf.conf but apparently doveconf doesn't properly print it. # 2.2.18: /etc/dovecot/dovecot.conf # OS: Linux 4.0.7-300.fc22.x86_64 x86_64 Fedora release 22 (Twenty Two) default_client_limit = 2000 mail_gid = mail mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u mail_plugins = " listescape" mail_privileged_group = mail mbox_write_locks = fcntl namespace { inbox = yes location = prefix = separator = $ type = private } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } passdb { driver = pam } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service imap-login { inet_listener imap { port = 0 } inet_listener imaps { port = 993 } process_min_avail = 20 service_count = 0 } service pop3-login { inet_listener pop3 { port = 0 } inet_listener pop3s { address = 192.168.1.100 port = 995 } } ssl_ca = </etc/pki/dovecot/certs/ca-bundle.pem ssl_cert = </etc/pki/dovecot/certs/orion-2015.pem ssl_key = </etc/pki/dovecot/certs/orion-2015.key userdb { driver = passwd } userdb { driver = passwd }

Hello, Yesterday I tried to back up a 40GB maildir . I tried to move the maildir from home to external HDD but failed. Decided then to compress it(which took several hours). Now changing the disk format from FAT to exFAT to allow the transfer for the large compressed file. How does one back up emails on a external drive? Some advice would be greatly appreciated.

need help debugging deleted mails
by Vu Ngoc VU 13 Aug '15

13 Aug '15

hello, one of our users complained about the fact that he doesn't receive some messages (randomly) that his teamates have. Grepping for the message-ID in the mail.log, I can see lmtp says it is saved : Aug 12 15:23:23 imap-01 dovecot: lmtp(4943, johndoe(a)example.net) fFuCO09Hy1VPEwAA2t/0+w: sieve: vsize= msgid=<037e01d0d502$0e3687d0$2aa39770$(a)example.net>: stored mail into mailbox 'INBOX' The only difference with others recipients is the 'sieve:... stored mail' instead of 'saved mail to' when there is no sieve. But when he asked me, the message was no more in his maildir (I checked with doveadm search). As we have checked and disabled all the filters in his MUA and on the server (sieve) and this issue still continue, I did mkdir a dovecot.rawlog inside his home. With the help of rawlog, I can see that the message can be found in a .out file (by grepping the Message-ID). And by reading this .out log raw log, the entire message were sent to the client. So I guess that : * the message was written to disk * it was sent to the MUA But I need your help because I don't get how this message disappear from his maildir. My assumptions was that the client must do some commands like : * STORE the \Deleted flag to this message UID * and then, later do EXPUNGE but I did : * grep -i expunge * 20150812* => no match * grep -iE '\+flags .*\\deleted' => a few matches but not with the appropriate UID snippet from the 20150812-133858-13317.in file: 8nk1 UID FETCH 208209 (UID FLAGS RFC822.SIZE BODY.PEEK[HEADER] INTERNALDATE) p7uv IDLE DONE 6yk3 NOOP 83g6 IDLE DONE yhbd UID FETCH 208209 (UID FLAGS BODY.PEEK[]) fy16 IDLE DONE snippet from the 20150812-133858-13317.out file: * 56295 FETCH (UID 208209) wn2p OK Fetch completed. * 56295 FETCH (UID 208209 FLAGS (\Deleted \Seen \Recent) RFC822.SIZE 17138 INTERNALDATE "12-Aug-2015 15:23:22 +0200" BODY[HEADER] {2836} Considering these points: * I cannot find any match with 208209 early in raw logs * I don't see any expunge for the whole day * I've grepped for \Deleted (insensitive) and didn't find matching like a interval of messages UID. What did I miss to find out how/when the message got \Deleted flag and was removed from his maildir? A few about my setup : * system is ubuntu 14.04 inside OpenVZ containers (Proxmox) * dovecot version is 2.2.9 from Ubuntu packages * 2 director with Internet and local ip addresses * 2 backends with only local addresses * these dovecot access storage servers by NFSv3 (that's why we have director) * imap/lmtp are proxied Thanks a lot for reading, I'm really disappointed about this problem. For the moment, I'll delete his script even if all rules are disabled (via roundcube, and I checked the rule is commented in the file). And also I'll try to watch what happens with inotify on the storage server.

SiS does not work

How do you do. I have tried to use SiS to deduplicate attachments in mail storage. Unsuccesful. When goes mail with reasonable size, and SiS try to start, I have receive error, when this mail must be delivered for group of receivers (i.e. through aliases).

userdb / user map with director
by Will Yardley 10 Aug '15

10 Aug '15

This is with dovecot-ee 2.2.18.2 on RHEL6.... To handle backend and frontend on same machine, I'm using the following hack, as previously outlined here: [in director instance config] passdb { # See thread ending in: # http://dovecot.org/pipermail/dovecot/2012-June/083817.html # for why this has to be sql instead of 'static' driver = sql args = /etc/dovecot/dovecot-sql.conf } [in /etc/dovecot/dovecot-sql.conf] driver = sqlite connect = /etc/dovecot/empty.db password_query = select 'y' as proxy, \ NULL as password, \ 'y' as nopassword, \ case '%a' \ when '110' then '10110' \ when '995' then '10110' \ when '143' then '10143' \ when '993' then '10143' end \ as port; This works, but I was getting a failure on usernames, since director instance didn't have a userdb. So I tried the following: [in config] passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf } userdb { driver = prefetch } and appended the following to the SQL query: password_query = select '%u' AS user, \ Then I see the following error in the log when I try to run the map "Trying to iterate users, but userdbs don't support it" and doveadm -i director director map returns: Error: User listing returned failure Error: user listing failed [...] I'm sure I'm missing something obvious, so is there an easy fix to make this mapping work? w

Dovecot sends "OK Logged in" with empty tag
by Simon Thelen 10 Aug '15

10 Aug '15

Hello, I'm currently writing my own IMAP client and testing it against Dovecot, and when doing PLAIN AUTH Dovecot sends the "OK Logged in" with an empty tag at the start. I tried reproducing the conversation with netcat, but Dovecot sends a correctly tagged OK at the end of the AUTH so I assume it's timing related. I've attached pcap dumps of the TCP conversation in both situations as well as the output of dovecot -n. Side Note: Why does Dovecot send the updated capabilities before OK'ing the authentication? Seems strange to me as the client can't assume that the authentication proceeded successfully until it actually receives the OK so it has to assume that those capabilities are pre login. -- Simon Thelen

Using a separate passdb per service
by Gerry 10 Aug '15

10 Aug '15

Situation: one front-facing server running Dovecot as IMAP/POP3/ ManageSieve proxy, a mixture of IMAP servers (Dovecot, Exchange, ...) in the back-end. Dovecot's passdb does lookups against MySQL which contains a simple user/host mapping, the actual authentication happens on the back-end IMAP servers. The configuration is more or less as described here: http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy Now I would like to add a Postfix instance on the front-facing server which listens on the submission port and authenticates users via SASL using the local Dovecot's UNIX socket. The idea being that a user only needs to remember one single hostname, one username and one password for all mail-related services. The problem is that Dovecot is operating in proxy mode, which means that the password_query returns NULL as the password and explicitly returns a field "nopasswd" containing "Y". Thus, users can not authenticate against the UNIX socket. What I think I want to do is convince Dovecot to use one passdb for the imap/pop3/managesieve services and different one for the "auth" service. The configuration snippet below doesn't work, but it should illustrate what I want to achieve: > protocols = imap pop3 sieve > > service auth { > passdb sql { > driver = sql > args = /etc/dovecot/mysql-auth-sasl.conf.ext > } > > unix_listener /var/spool/postfix/private/auth { > user = postfix > group = postfix > mode = 0666 > } > } > > # IMAP/POP3/ManageSieve auth against MySQL > passdb sql { > driver = sql > args = /etc/dovecot/mysql-auth-default.conf.ext > } Example mysql-auth-sasl.conf.ext > driver = mysql > connect = host=127.0.0.1 dbname=mail user=mail password=somethingrandom > password_query = SELECT password AS password FROM users WHERE login = '%u' Example mysql-auth-default.conf.ext: > driver = mysql > connect = host=127.0.0.1 dbname=mail user=mail password=somethingrandom > password_query = SELECT NULL AS password, 'Y' as nopassword, host, 'Y' AS proxy FROM users WHERE login = '%u' Any pointers?

Trying to back
by Kevin Laurie 09 Aug '15

09 Aug '15

Hi, I am trying to backup multiple mail accounts by using imapsync and Dovecot on my local machine. I am using maildir as a mail storage format and currently have the following setting on my local machine :- mail_location = maildir:~/Maildir I am afraid that if I imapsync multiple accounts they will all get stored in the same location. Is there a way to seperate the accounts based on the email address? Appreciate if someone could advise. Thanks! Kevin

Dovecot/Pigeonhole Issue (UTC modtime instead of localtime)
by Christoph Gröver 06 Aug '15

06 Aug '15

Hi List, We are using the following setup: Dovecot-2.2.18 Pigeonhole-0.4.8 (for Dovecot-2.2) After the mail is finally delivered via a fileinto by the Sieve filter it gets an updated timestamp (modification time). The server has localtime setup correctly IMO (UTC +0200), but still the delivered mail is setup as being two hours old. I think I found out that the function sieve_file_storage_update_mtime() is the cause of this problem. But perhaps there has to be some kind of setup, that tells pigeonhole to use the 2 hour offset of CEST. I think to reset the mtime by utime(s) is a bit strange. It already gets the correct modtime just by storing it in the filesystem. Last version we used (0.2.5) did not have this poblem. So it must be there for some reason? Perhaps you can enlighten me. Thanks for your time.

Renaming shared mailbox makes it disappear from sharee
by Andy Csillag 03 Aug '15

03 Aug '15

I've run into an interesting thing. If a mailbox has been shared to a second user (I'll call it the sharee), and there are subfolders on that mailbox, and the sharee renames one of those subfolders, it disappears from view to the sharee. The only way I've been able discover to fix it is to have the sharee create a new subfolder -- then the renamed folder shows up again; in addition to the newly created folder. For example, first(a)example.org shares it's INBOX to second(a)example.org. There's a folder INBOX/thing, which second@ renames to INBOX/renamed (ACLs permitting). second@ can no longer can see INBOX/renamed (or INBOX/thing for that matter), via IMAP's LIST command. But if second@ creates a new folder INBOX/other, INBOX/renamed is now visible. This is very reproducible for me. I also tried it without the imappostlogin bit (in the dovecot -n). Anyone else run into this? No NFS is involved, this is a single machine setup.

Structure of dovecot.index.pvt.log

Hi, we are migrating from Cyrus to Dovecot and I would like to migrate seen flags for shared folder too. We have Dovecot 2.2.13 prepared as: location = maildir:/vmail/user/%%n/Maildir:INDEXPVT=/vmail/user/%n/Maildir/Shared/%%n Now I'm looking for 'dovecot.index.pvt.log' syntax to be able migrate Seen flags. All I know is, that index contains messages UID and Seen flag. May I ask you for a link to doc (if it exists) or into a source code? Should I care about 'dovecot.index.pvt.log' timestamps?

Question RE listescape and separators
by Jakob Curdes 30 Jul '15

30 Jul '15

Hello, we just start moving a large number of mailboxes to a new dovecot server with dovecot 2.0.9 (from CentOS) and sdbox as mailbox type. We use imapsync so there is no issue with mailbox type conversion. However, in test runs I noted that some mail folders,e.g. with dots in them, could not be transferred; dovecot says Couldn't create folder [7.8) Personnel] from [7.8) Personnel]: 106 NO Character not allowed in mailbox name: '.' We have the separator "/" defined for our only namespace so the dot should not be an issue!? I tried to use listescape but either the plugin is not loading (how can I verify this?) or it does not escape the dot in the mailbox name. The listescape settings are the defaults: namespace { separator = / (...) } mail_plugins = $mail_plugins listescape plugin { listescape_char = "\\" } What am I doing wrong? How can I make dots in mailboxes possible? Best regards, Jakob Curdes

Deafness
by Steffan Cline 29 Jul '15

29 Jul '15

I’ve started in the last day or so having issues where users get a timeout when connecting to dovecot. The iPhone interprets this as an auth issue but re-entering the password makes no change. Outlook will either just not connect to it at all or it gives an error to re-enter the password also with no change. This happens within an hour of a "service dovecot restart". I’m using CentOS 6 with dovecot 2.0.9 from the centos repos. There’s nothing visible in the logs. Suggestions of what to check for? Thanks, Steffan

dbox: message internal date
by Francesco 29 Jul '15

29 Jul '15

Hello everyone and thanks in advance for the help :) I'm trying to figure out where does dovecot store the message internal date when using single dbox storage format. In Maildir format, the internal date is determined by the actual date of the file on the filesystem, but in dbox it doesn't seem to be the case. I'm looking forward for a way to modify a message internal date when on a dovecot instance running dbox storage engine, maybe anyone knows if it's possible and how to accomplish this? Again, thank you for the help Sincerely Francesco

Importing mbox archives into a inbox?
by Paul Hoffman 27 Jul '15

27 Jul '15

Greetings from a dovecot newbie. I have a bunch of mailing list archives (in mbox) format that I want to dump into the inbox for a particular account on the system. I want them to retain all of their information, particularly the date. I'm not seeing how to do this, but I could be missing it. Is this LDA or LMTP with some command-line options I'm not seeing? --Paul Hoffman

POP3 getting previously delivered messages.
by Jas Reehal 24 Jul '15

24 Jul '15

Hi All, This is my first post to this list. I have recently upgraded to dovecot version 2.2.10. 1. I have one POP3 user who does not want to delete his email on the server. 2. He has accumulated over 19000 messages, and the 'dovecot.uidlist' file has more than 19000 lines! 3. Occasionally now when he has received one or more new emails, and his email client does a 'get new mail' operation (POP3) he begins to receive email he has already received previously. last time this happened all 19000+ messages were delivered again, leaning to duplicate entries in all his mailboxes. I have reproduced this issue with a dummy email account with a POP3 client, leaving all messages on the server. I have delivered 20000 messages to this email account, each about 1.3k ins size and each with .... Subject: Message number <n> Body containing "Message number <n>" where <n> is 1 to 20000 now occasionally if I send another message to this email account, and then check for new messages using a POP3 client I get more messages downloaded than I expect! The 'dovecot.uidlist' file is not corrupt, but I beleive due ti it's size (number of lines) the is an issue on compiling a ' POP3 drop-list'. I have attached a file 'dovecot-a.txt' which shows the 'dovecot -a' output from my server. Based on what I have investigated I believe that this issue may not be correlated with a migration to version 2.2.10, but more to do with the number of messages retained on the server. Is there anyone who has any insight into what is happening and if there is any remedy, perhaps a "pop3_client_workarounds =" or other POP3 or UIDL directive in the conf files? The user is stubbornly resisting migration to IMAP, because of the time and effort he says will be required to replicate his organised filing/storage of messages on the server.

possible patch for ACL SQL ERROR: duplicate key value violates unique constraint "user_shares_pkey"
by Steffen Kaiser 24 Jul '15

24 Jul '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm using Postgres as dict backend now and then I get this error, when someone changed ACLs, actually for some reason some users, who get permission from other users, get this error quite often: dict: Error: sql dict: commit failed: ERROR: duplicate key value violates unique constraint "user_shares_pkey" (query: INSERT INTO user_shares (dummy,to_user,from_user) VALUES ('1','user1','user2')) It looks like that this error is triggered, when a MUA is connecting to Dovecot after ACLs had been changed and opens several mailboxes at once. So two or parallel Dovecot instances try to insert the record simultaneously. With a similiar technique to the quota problem, I added a trigger. The idea is to use the condition dummy ISNULL to detect, that the function was triggered from the INSERT of the function itself, hence, breaking the recursive triggers. This assumes that dummy is never NULL from Dovecot. The same applies to anyone_shares, just remove the to_user field from the function. Does somebody see something wrong with my hack? ============= CREATE FUNCTION insert_sharing() RETURNS trigger LANGUAGE plpgsql AS $$ BEGIN IF NEW.dummy IS NULL THEN -- ugly kludge: we came here from this function, really do try to insert return NEW; END IF; LOOP UPDATE user_shares SET dummy = NEW.dummy WHERE from_user = NEW.from_user AND to_user = NEW.to_user; IF found THEN -- updated and inserted RETURN NULL; END IF; BEGIN INSERT INTO user_shares (from_user,to_user,dummy) VALUES (NEW.from_user,NEW.to_user,NULL); --- return NULL; EXCEPTION WHEN unique_violation THEN -- someone just inserted the record, update it END; -- Update dummy after INSERT END LOOP; END; $$; CREATE TRIGGER insertsharing BEFORE INSERT ON user_shares FOR EACH ROW EXECUTE PROCEDURE insert_sharing(); - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEVAwUBVbHxJXz1H7kL/d9rAQIn5gf/dNMQKmmigGrbccGQQrsGU66B6OHvTY7L 1vyh8hgr985KNk2/Ws/usLnAqpl5jhpo8kVPLI8TqcGYLAS/67TOIFrwLKAEBU96 e+QpbqqiSm66mZwWOQZgCI63+Fh7fdBUMREL6UqGleFF1GrzNnjmX4MGecbpu/L9 gQMAGUG++/S+ka9S6B275RXIj9DvWzq/oYqJ1M1grGckUxXfDk5szLyvuIJ981At 20qaCHEIlIOlkQ0ttE4W+RWkkYS2rMJvCzQelF4pcm6vaxhXxvqUryzmy9pv+UUT osqS6igWt7BPXF7ku8+rKYVp/qPZrh9IWXMsajr/2nI+V5gRb6u2ow== =gb1P -----END PGP SIGNATURE-----

Authenticate system user with alternate password
by AC 22 Jul '15

22 Jul '15

Is there a way to configure Dovecot to authenticate a system user against a different password list? I want to give my own personal account on my machine a password for IMAP and have that be different from the password I use to log into the system for maintenance purposes. I currently do this for outbound email by having the MTA authenticate against a SASL database during the initial SMTP connection (STARTTLS).

dovecot proxy/director and high availability design
by Chad M Stewart 21 Jul '15

21 Jul '15

I'm trying to determine which dovecot components to use and how to order them in the network path from client to mail store. If I have say 1,000 users, all stored in MySQL (or LDAP) and have 4 mail stores, configured into 2, 2 node pods. MS1 and MS2 are pod1 and are configured with replication (dsync) and host users 0-500. MS3 and MS4 are pod2 and are configured with replication between them and host users 501-1000. Ideally the active connections in pod1 would be split 50/50 between MS1 and MS2. When maintenance is performed obviously all active connections/users would be moved to the other node in the pod and then rebalanced once maintenance is completed. I'm not sure if I need to use both the proxy and director, or just one or the other? If both then what is the proper path, from a network perspective? I like the functionality director provides, being able to add/remove servers on the fly and adjust connections, etc.. But from what I've read director needs to know about all mail servers. The problem is that not all servers host all users. User100 could be serviced by ms1 or ms2, but not by ms3 or ms4. I'm trying to design a system that should provide as close to 99.999% service availability as possible. Thank you, Chad

Dovecot in UCS
by Daniel Tröder 21 Jul '15

21 Jul '15

Hello :) I hope you can forgive me a little advertisement: The English translation of my blog post on the Dovecot integration I did for the Univention Corporate Server (UCS) is online: https://www.univention.com/2015/07/dovecot-is-the-default-imappop3-mail-ser… UCS is a Debian based Linux Distribution, everything - incl. management bits - is OSS. There is a "Core Edition" that you can download and use (also commercially) for free, that is - despite its name - feature complete: https://www.univention.com/downloads/ucs-download A lot of interesting Dovecot features can be changed without breaking things, so this blog post may be interesting to everyone.

[Dovecot Antispam] Can't seem to load plugin
by James Lott 21 Jul '15

21 Jul '15

Hello list, I'm hoping there is a user of the antispam plugin out there who might be able to lend a pointer or two. I am running dovecot 2.2.18 on FreeBSD 10 (doveconf -n attached), where I have installed the binary dovecot2-antispam-plugin package. I have put together what should, in my estimation, be a working configuration for the plugin. I have reviewed the man page and the online documentation, and I think at the *very least* I should be seeing errors for something not working correctly. However, what I have is a great deal more troubling. There is no sign on the plugin even attempting to load. No log entries, no errors, nothing. The plugin is definitely in the right place with the right name, since I let the package manager handle all of that for me root@zerolag:~ # ls -l /usr/local/lib/dovecot/lib90_antispam_plugin.so -rwxr-xr-x 1 root wheel 32488 Jul 2 09:41 /usr/local/lib/dovecot/lib90_antispam_plugin.so I am unable to make any sense of this. Thanks in advance for any pointers :) -- James Lott

by dominik 20 Jul '15

20 Jul '15

Hello dovecot community, first of all: dovecot ist great! ;) ...nevertheless I´ve got some problems to get my director scenario running as needed/expected :( My scenario: I´d like to configure two dovecot backends, without the need for multiple dovecot instances. Both backend servers are active/active and act on top of a glusterfs storage, which implies the need for dovecot director. As described in release notes (v2.2.17) this should be possible by setting the extra field "director_proxy_maybe=yes".: "+ director: Implemented director_proxy_maybe passdb extra field to be able to run director and backend in the same Dovecot instance. (LMTP doesn't support mixed proxy/non-proxy destinations currently.)" My setup: * 1 LMTP client (SLES11p3 with postfix) * 1 IMAP/POP3 client (Debian8 with thunderbird 31.6.0): 10.0.0.26. The client connects through a dovecot mailproxy or direct. * 1 dovecot mailproxy: 10.0.1.151 * 2 mailbox backends running dovecot v2.2.18 on SLES11p3 with mail_location pointing to a glusterfs-mountpoint (GlusterFS: v3.6.3) * mailbox01.example.de: 10.0.2.21 * mailbox02.example.de: 10.0.2.22 * mailbox-gluster.example.de points as an A-RR to 10.0.2.21 and 10.0.2.22. My problem: With LMTP everything works fine (thanks for this!). The director sets the "host" field correctly and all delivery attempts work fine to the estimated backend servers. But when I try to connect via IMAP-/POP3-client (through proxy or direct) it fails with following log messages. It seems, that the director doesn´t set the host field within IMAP/POP sessions before proxying!? auth: Debug: auth client connected (pid=46359) imap-login: ID sent: x-session-id=V3iJmU4biAAK/BAa, x-originating-ip=10.0.0.26, x-originating-port=54408, x-connected-ip=10.0.1.151, x-connected-port=143, x-proxy-ttl=4: user=<>, rip=10.0.1.151, lip=10.0.2.21, session=<RVnAm04bzwAK/FCX> auth: Debug: client in: AUTH 1 PLAIN service=imap session=RVnAm04bzwAK/FCX lip=10.0.2.21 rip=10.0.1.151 lport=143 rport=54735 resp=<hidden> auth: Debug: ldap(tester(a)example.de,10.0.1.151,<RVnAm04bzwAK/FCX>): bind search: base=o=example,c=de filter=(&(|(uid=tester@example.de)(mail=tester@example.de))(!(<cut-cut-cut>)) [...] auth: Debug: client passdb out: OK 1 user=tester(a)example.de director_proxy_maybe=yes lip=10.0.2.21 lport=143 proxy pass=<hidden> imap-login: Debug: Ignoring unknown passdb extra field: director_proxy_maybe imap-login: Debug: Ignoring unknown passdb extra field: lip imap-login: Debug: Ignoring unknown passdb extra field: lport imap-login: Error: proxy: host not given: user=<tester(a)example.de>, method=PLAIN, rip=10.0.2.151, lip=10.0.2.21, session=<RVnAm04bzwAK/FCX> imap-login: Disconnected (internal failure, 1 successful auths): user=<tester(a)example.de>, method=PLAIN, rip=10.0.2.151, lip=10.0.2.21, session=<RVnAm04bzwAK/FCX> Finally the output of "doveadm proxy list" is empty!

bug in group permission check

Jul 19 01:05:27 sv1 dovecot: auth: Error: passwd-file(aa@ddd,89...24,<>): stat(/usr/dovecot-cfg/dom-home/ddd/etc/ddd/shadow) failed: Permission denied (euid=33454(dovecot) egid=33454(dovecot) missing +x perm: /usr/dovecot-cfg/dom-home/ddd, we're not in group 33795(sysgroup), dir owned by 32072:33795 mode=0710) root@sv1 [~]# sudo -u dovecot groups dovecot sysgroup root@sv1 [~]# sudo -u dovecot cat /usr/dovecot-cfg/dom-home/ddd/etc/ddd/shadow <prints content of the file> It seems that dovecot incorecly checks for group permissions not even trying to access file - probably cant handle that dovecot is part of more than 1 group. When its part of single group problem is not occuring.

Helper to open "/doc/wiki/.." paths; suggestions
by Christian Jaeger 17 Jul '15

17 Jul '15

I wrote this script to have an easier time looking at the doc paths referenced from the default configuration files (currently using dovecot in Debian oldstable). Feel free to include in the distribution or wherever. Probably a better solution would be to publish the config files with the paths already expanded to the online URL, or a local filesystem path that works (in the latter case, I'd wish the docs would be bundled in html format). I wonder whether to approach the debian maintainer about this or the Dovecot team? Definitely something for the maintainer is to put the bundled docs in a place where I would have expected it (/usr/share/docs/dovecot/wiki/ instead of /usr/share/docs/dovecot-core/dovecot/wiki/, or a dovecot-doc package, also, links or mentions from the doc dirs of all dovecot packages to the docs). Also, I think there should be a README document that serves as the first introduction of the user to how to configure the system: how are the config files split up, what does "!include" mean (why the "!"? Is it a comment char?), other rules on the config file format. I.e. the basics to enable the new user to go about reading the current config and where to find further docs/help. Thanks & Cheers, Christian.

Getting duplicated mails while using imapc and dsync
by Michael 17 Jul '15

17 Jul '15

Hello list, currently I'm migrating our old mailserver to a new mail architecture that is based on a master-master dovecot setup (two machines). The replication actually works but I'm also syncing our mails from the current mailserver via imapc on a regular schedule. For some reason I've in most (but not all) imapc-synced mailboxes duplicated emails that I also can't deduplicate with doveadm. I've also set up test-mailboxes that I don't sync with imapc and in those I don't have any duplicated mails. My command to sync the mails from the old host to the master-master system looks as follows: doveadm -o imapc_user=$i*dovemig -o imapc_password=<password> -o imapc_host=<oldhost> -o imapc_features="rfc822.size fetch-headers" -o mail_prefetch_count=20 -v -D sync -R -u$EMAIL imapc: &> $LOGS/$i.log So, is this actually the wrong approach to sync mails from the old host to the new one or is it just not recommended to sync them over-and-over again in such a setup via imapc or is it better to sync them only once? Any hint/pointing me to the right solution is greatly appreciated. Michael

Dovecot-EE repository for Debian 8 (Jessie/stable)
by Bernhard Schmidt 17 Jul '15

17 Jul '15

Hi, are there plans to support Debian 8 (alias stable, alias jessie) in the dovecot-ee repository? Currently there are only squeeze and wheezy repos. The wheezy repo is uninstallable due to an unsatisfyable dependency on libicu48. Of course you can install libicu48 from Wheezy on a Jessie system, but this will break security updates and might not be the best idea for a library like that. Bernhard

Quota policy service not rejecting messages when user over quota
by james＠lottspot.com 17 Jul '15

17 Jul '15

For some very odd reason, the quota-status service is failing to enforce quotas. Every other aspect of my configuration is working with absolutely no problems. When I attempt delivery via LTMP, the message is, as expected, rejected due to the user's inbox being full. root@smtp:/usr/local/etc/mail-config # nc -U /var/spool/postfix/private/dovecot-lmtp < 220 mx0.lottspot.com Dovecot ready. > LHLO localhost < 250-mx0.lottspot.com < 250-8BITMIME < 250-ENHANCEDSTATUSCODES < 250 PIPELINING > MAIL FROM:<root@localhost> < 250 2.1.0 OK > RCPT TO:<james(a)lottspot.vpn> < 552 5.2.2 <james(a)lottspot.vpn> Quota exceeded (mailbox for user is full) The policy service however, just lets everything go right through. I know that accessing the userdb is not an issue, because I passed a bogus user before passing my real user and received the expected response. root@smtp:/usr/local/etc/mail-config # nc -U /var/spool/postfix/private/policy-quota > recipient=noop(a)fake.tld > < action=551 User not found < > recipient=james(a)lottspot.vpn > < action=250 Quota status success < I'm using Dovecot 2.2.15, and I have included my quota configuration below. If anyone wants to see full doveconf -n output, I can provide it, but figured it was a bit much for this case. Thanks in advance for any pointers! --> Note: I'm the quota_status_* directives have been set as is for testing purposes only. I'm fully aware not to do that in production. plugin { quota = maildir:User quota quota_rule = *:bytes=1G quota_rule2 = Trash:storage=+10%% quota_status_success = "250 Quota status success" quota_status_nouser = "551 User not found" quota_status_overquota = "552 5.2.2 Recipient mailbox is full" } service quota-status { executable = quota-status -p postfix unix_listener /var/spool/postfix/private/policy-quota { user = postfix group = wheel mode = 0666 } }

[Sieve] Unable to fileinto subfolders
by james＠lottspot.com 17 Jul '15

17 Jul '15

Hello again list! I am configuring a server running Dovecot 2.2.15 (Pigeonhole 0.4.6), and I am having an issue with Sieve scripts where I cannot sort messages into a subfolder of a mailbox. An email which is matched by the following script: require "fileinto"; if header :contains "Subject" "[SORT ME]" { fileinto "INBOX.Sorted"; } Yields the following error: Jul 16 18:54:46 smtp dovecot: lmtp(james(a)lottspot.vpn): Error: DiJmNGZgqFWLFAEANWXNPw: sieve: msgid=<4973528.yvy4Yu8Tt4@arch_project>: failed to store into mailbox 'INBOX.Sorted': Character not allowed in mailbox name: '.' As far as I can tell based on the Sieve usage page in the wiki (http://wiki2.dovecot.org/Pigeonhole/Sieve/Usage) this is *supposed* to work. I have included my namespace configuration below, but if anyone wants the whole doveconf -n, I will gladly provide it. Thanks in advance for any help! namespace inbox { type = private separator = / prefix = inbox = yes mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Spam { auto = subscribe special_use = \Junk } mailbox Trash { auto = subscribe special_use = \Trash } } namespace { type = shared separator = / prefix = shared/%%d/%%n/ location = maildir:/home/%%d/%%n/mail:INDEX=~/indexes/%%d/%%n:INDEXPVT=~/indexes/%%d/%%n subscriptions = no list = children }

question on Dovecot replication
by Arnold Wang 17 Jul '15

17 Jul '15

I'm running Dovecot 2.2.x and have a question on its replication capability. I plan to run Dovecot in two different sites with two nodes at each site. My question is how many replication partners can each Dovecot node have? Can I define three "mail_replica" entries in every node so any message received by one node will be replicated to three other nodes automatically? Thanks in advance for your help.

Admin access to sieve filters with managesieve
by Christian Theune 15 Jul '15

15 Jul '15

Hi, I’ve been a long-time user of Cyrus and started using sieve with Dovecot recently. A question that came up is: how do I access a users’s sieve scripts through managesieve without their credentials? Managesieve allows separating authentation and the corresponding mailbox identification, right? That’s what I used with cyrus sieve all the time. :) I didn’t find documentation in the wiki or googling where to configure someone as admin in Dovecot so he can access foreign sieve scripts through managesieve. Pointers? Am I using the right words?

doveadm search -A problem with dropped privileges
by Sebastian Kricner 14 Jul '15

14 Jul '15

Hello, if you want to answer to this mail, please send it directly to me. I have found a big issue with the following command "doveadm -search -A". It whatsoever works by setting doveadm_worker_count = 0 in the dovecot.conf configuration file. The problem is that doveadm-server or something similar uses privileges of "nobody" and so it fails searching e-mails. Instead also the process tries to create a maildir for "nobody": Debug: Namespace : /var/mail/nobody doesn't exist yet, using default permissions Debug: Namespace : Using permissions from /var/mail/nobody: mode=0700 gid=default Error: User initialization failed: Namespace '': mkdir(/var/mail/nobody) failed: Permission denied (euid=65534(nobody) egid=65534(nobody) missing +w perm: /var/mail, we're not in group 12(mail), dir owned by 0:12 mode=0775) Error: search: User init failed Error: userdb lookup: connect(/var/run/dovecot//auth-userdb) failed: Permission denied (euid=65534(nobody) egid=65534(nobody) missing +r perm: /var/run/dovecot//auth-userdb, we're not in group 12(mail), dir owned by 0:0 mode=0755) Error: search: User lookup failed: Internal error occurred. Refer to server log for more information. Even after setting permissions, so that the process can create a maildir for "nobody" in the /var/mail location, it fails to "setresgid" to the particular user to be scanned. It can´t work because it is not possible to gain other user privileges from another user. # 2.2.16: /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.7 # OS: Linux Gentoo Base System release 2.2 auth_cache_negative_ttl = xx mins auth_cache_size = xx M auth_cache_ttl = xx mins auth_mechanisms = xx xx auth_worker_max_count = xx base_dir = /var/run/dovecot/ default_process_limit = xx dict { expire = sqlite:/xx } doveadm_worker_count = 1 first_valid_gid = xx first_valid_uid = xx login_greeting = xx.xx mail_location = maildir:/xx/xx/%u mail_privileged_group = xx managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate passdb { args = scheme=SHA512 /xx/xx/xx.xx driver = passwd-file } plugin { expire = xx expire2 = xx expire_dict = proxy::expire sieve = ~/.xx.xx sieve_dir = ~/.xx } protocols = imap sieve service auth { unix_listener auth-client { group = xx mode = 0660 } unix_listener auth-userdb { group = xx mode = 0660 } } service dict { unix_listener dict { mode = 0666 } } service imap-login { inet_listener imap { port = 0 } process_limit = 6 service_count = 1 } ssl_cert = </xx/xx/xx/xx.xx.xx ssl_key = </xx/xx/xx/xx.xx.xx ssl_parameters_regenerate = xx days userdb { driver = passwd } protocol lda { mail_plugins = sieve expire } protocol imap { imap_idle_notify_interval = xx mins mail_max_userip_connections = xx mail_plugins = expire } Regards Sebastian Kricner -- http://tuxwave.net -- the difference to think makes it real!
