Hi, We are currently moving from linuxconf/dovecot to a dovecot setup with sql support, the problem we currently facing is having a message sent to a aliase delivered to the user email inbox with dovecot-lda, i have created cedrict(a)mail.vdl and a alias test(a)mail.vdl, when i send to cedrict(a)mail.vdl the message is included in the user inbox file, but when i send to test(a)mail.vdl it should do the same and not create a new created file named test, thank in advance for your help. # dovecot --version 2.2.4 dovecot.conf auth_debug = yes auth_debug_passwords = yes auth_verbose = yes default_internal_user = root default_login_user = mail disable_plaintext_auth = no first_valid_uid = 100 mail_access_groups = mail users sysadmin popusers mail_location = mbox:%h/mail:LAYOUT=maildir++:INDEX=MEMORY:CONTROL=%h/mail/control:INBOX=/var/spool/vmail/%d/%n mail_max_userip_connections = 40 mail_plugins = " quota sieve" managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave mbox_lazy_writes = no passdb { args = /vdl/etc/dovecot/dovecot-sql.conf driver = sql } plugin { sieve = %h/mail/sieve/%n sieve_global_dir = /vdl/etc/dovecot/ sieve_vacation_default_period = 1d sieve_vacation_max_period = 7d } postmaster_address = x(a)x.x protocols = imap pop3 service auth { unix_listener auth-userdb { mode = 0600 user = popusers } } service imap-login { inet_listener imap { port = 143 } process_min_avail = 4 vsz_limit = 256 M } service pop3-login { inet_listener pop3 { port = 110 } process_min_avail = 16 } ssl = no submission_host = localhost:25 userdb { args = /vdl/etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { mail_plugins = quota imap_quota mail_log notify } protocol pop3 { mail_plugins = quota } protocol lda { mail_plugins = quota sieve } dovecot-sql.conf password_query = SELECT \ concat(s_courriel_utilisateur.utilisateur, '@', s_courriel_domaine.nom) AS user,s_courriel_utilisateur.password as password \ FROM s_courriel_utilisateur left join s_courriel_alias on s_courriel_utilisateur.id=s_courriel_alias.utilisateur and s_courriel_alias.archive !=1 ,s_courriel_domaine \ WHERE s_courriel_utilisateur.archive !=1 \ and s_courriel_domaine.archive !=1 \ and s_courriel_utilisateur.domaine=s_courriel_domaine.id \ and s_courriel_domaine.nom = '%d' \ and ( s_courriel_utilisateur.utilisateur = '%n' or s_courriel_alias.alias = '%n' ) user_query = SELECT \ concat("/vhome/",s_courriel_domaine.nom,"/home/",s_courriel_utilisateur.utilisateur) as home, \ concat("/vhome/",s_courriel_domaine.nom,"/home/",s_courriel_utilisateur.utilisateur,"/mail/index") as "index", \ concat("/vhome/",s_courriel_domaine.nom,"/home/",s_courriel_utilisateur.utilisateur,"/mail/control") as control, \ concat("/var/spool/vmail/",s_courriel_domaine.nom,"/",s_courriel_utilisateur.utilisateur) as inbox, \ "maildir++" as layout, \ s_courriel_utilisateur.uid as uid,s_courriel_domaine.gid as gid \ FROM s_courriel_utilisateur left join s_courriel_alias on s_courriel_utilisateur.id=s_courriel_alias.utilisateur and s_courriel_alias.archive !=1 ,s_courriel_domaine \ WHERE s_courriel_utilisateur.archive !=1 \ and s_courriel_domaine.archive !=1 \ and s_courriel_utilisateur.domaine=s_courriel_domaine.id \ and s_courriel_domaine.nom = '%d' \ and ( s_courriel_utilisateur.utilisateur = '%n' or s_courriel_alias.alias = '%n' ) Transaction debug for cedrict(a)mail.vdl with message added to file /var/spool/vmail/mail.vdl/cedrict SELECT concat("/vhome/",s_courriel_domaine.nom,"/home/",s_courriel_utilisateur.utilisateur) as home, concat("/vhome/",s_courriel_domaine.nom,"/home/",s_courriel_utilisateur.utilisateur,"/mail/index") as "index", concat("/vhome/",s_courriel_domaine.nom,"/home/",s_courriel_utilisateur.utilisateur,"/mail/control") as control, concat("/var/spool/vmail/",s_courriel_domaine.nom,"/",s_courriel_utilisateur.utilisateur) as inbox, "maildir++" as layout, s_courriel_utilisateur.uid as uid,s_courriel_domaine.gid as gid FROM s_courriel_utilisateur left join s_courriel_alias on s_courriel_utilisateur.id=s_courriel_alias.utilisateur and s_courriel_alias.archive !=1 ,s_courriel_domaine WHERE s_courriel_utilisateur.archive !=1 and s_courriel_domaine.archive !=1 and s_courriel_utilisateur.domaine=s_courriel_domaine.id and s_courriel_domaine.nom = 'mail.vdl' and ( s_courriel_utilisateur.utilisateur = 'cedrict' or s_courriel_alias.alias = 'cedrict');

[Dovecot] zlib error when running doveadm
by Michael Long 22 Jul '13

22 Jul '13

I manually fixed it by copying src/plugins/zlib/lib20_zlib_plugin.la to /usr/local/lib/dovecot/doveadm I do not understand why 'make install' won't do that? A bug perhaps?

[Dovecot] OT: SAN vs Flash only SAN-less VM architecture for data storage
by Charles Marcus 21 Jul '13

21 Jul '13

Hello all, I am investigating options for leveraging our companies two locations, to provide fault tolerance/redundancy for our VM infrastructure. I was looking at SAN storage options, but ran across an interesting article, and would like opinions. It sounds great, a real win-win as to cost *and* performance... We have redundant/identical hosts at each location that can fulfill the requirements discussed... http://www.storage-switzerland.com/Articles/Entries/2012/9/20_The_Benefits_… or http://tinyurl.com/khwuspo Stan, I'm especially interested in your take, considering your experience with high end SANs and VM storage environments... Thanks, -- Best regards, Charles

[Dovecot] Archiving mail
by Koenraad Lelong 18 Jul '13

18 Jul '13

Hi, I'm going to migrate my company-mailserver to new hardware. I would like to take the opportunity to archive some older mail. But I would like to have it still accessible, would this be possible with dovecot ? I mean, I would like to put that older mail from different users (I got about 50 users) on some read-only media but mount that media in the users mail-dirs. That way I will have less to backup after I backup that old mail and store it safely away. I can't convince my users to really clean up their mailboxes, so I backup more than 100GB mail while the total backup is a bit more than 300GB. Writing this I realise I could give each user a folder oldmail and symlink that to a read-only oldmail folder. Would this work ? I will have to find out how my backup-software can ignore the oldmail-folder. Thanks for any suggestions, Koenraad Lelong

[Dovecot] Password encryption type for dovecot & postfix saslauthd with mysql
by Simon 18 Jul '13

18 Jul '13

Hi There, We are using dovecot v2.2.4 (compiled from source) and postfix (yum install) on Centos 6.4. We are storing our virtual user config in mysql. Server 1 has dovecot/postfix and accepts incoming mail from our mail filter servers - this is purely for IMAP/POP services. Server 2 has postfix for our clients to send email via TLS/saslauthd. Both use the same (separate) mysql server for config. One issue is that we have a requirement to merge user / passwords for sending clients from two sources: 1) the dovecot mailbox list 2). another list. The dovecot user list is email + password. The other list is username + password. To that end we have created a view table in mysql that merges the two.. tables + view look a little like this: table: mail_users (for dovecot) email,password test(a)test1.com,CRAM-MD5_PASSWORD test2(a)test1.com,CRAM-MD5_PASSWORD bla(a)bla.com,CRAM-MD5_PASSWORD table: mail_senders_other username,password username1,CRAM-MD5_PASSWORD something_else,CRAM-MD5_PASSWORD view: mail_senders (for postfix) username,password test(a)test1.com,CRAM-MD5_PASSWORD test2(a)test1.com,CRAM-MD5_PASSWORD bla(a)bla.com,CRAM-MD5_PASSWORD username1,CRAM-MD5_PASSWORD something_else,CRAM-MD5_PASSWORD I have dovecot working fine, but just need a little push in the correct direction (please) to figure out the correct settings and password encryption scheme to make the above work. Many thanks! Simon

[Dovecot] Dovecot 2.2.4 does not create home directory?
by Dmitry . 17 Jul '13

17 Jul '13

Hi, Does not create, or something I did wrong? Here http://wiki2.dovecot.org/VirtualUsers/Home it is written Home vs. mail directory Home directory shouldn't be the same as mail directory. It's possible to do that, but you might run into trouble with it sooner or later. Some problems with this are: and Ways to set up home directory The home directory is the same as the mail directory. If for example home=/var/vmail/domain/user/ mail=/var/vmail/domain/user/mail/, set: mail_home = /var/vmail/%d/%n mail_location = maildir:~/mail I think I've done it so. And yet, here http://wiki.dovecot.org/HowTo/SimpleVirtualInstall it is written Users can be added by editing this file. Dovecot automatically notices the new users immediately after they're added. It also creates their home directories when the user logs in. However, the directory is not created.

[Dovecot] Variable similar to %u but providing the username changed by a database lookup?
by Axel Luttgens 17 Jul '13

17 Jul '13

Hello, Variable %u may be used in dovecot.conf whenever the "full username" is needed. But the expansion of %u returns the username before a possible change performed thru a password or user database lookup (e.g., in the case of a SQL database, thru as "AS user" clause). Is there a variable that would expand to the changed name when used in the configuration file? TIA, Axel

[Dovecot] Fail2ban and logging

I expect I need to change something on the logging, so that every attempt is seperate logged. But I don't know how. Is here somebody who knows how to get fail2ban correct working?

[Dovecot] courier to dovecot
by J Gao 17 Jul '13

17 Jul '13

Hi, All, I am new here and I need your advises. Here is my story: I have a mail server like this: - CentOS 5 32 bit (LAMP) - Postfix 2.3 - Courier - MailScanner Courier use maildir to save emails in /home/vmail/<virtual domain>/<user> / Now I want to build a new system on CentOS 6.4 64bit with postfix, dovecot and migrate all user accounts and their emails. I already installed CentOS 6.4, postfix and mysql. Also just installed Dovecot v2.2.4 from the RPM. Now I am looking into how to Is there a good instruction on how to do this kind of migration? I still prefer using the maildir system. If I just copy all users email from old server to new dovecot user maildir, will dovecot see these mails (and sub-folders) ? Do I need do anything extra? Thanks in advance. Gao -- __ _|==|_ ('')__/ >--(`^^') (`^'^'`) `======'

[Dovecot] reload without shutting imap connections down
by Hajo Locke 16 Jul '13

16 Jul '13

Hello, we have some problems with users who report connectionproblems to dovecot sometimes. According to the logs there are dovecot reloads at this times. Seems that a reload also causes dovecot to shut all imapconnections down: Jul 16 13:31:40 myhostname dovecot: master: Warning: SIGHUP received - reloading configuration Jul 16 13:31:40 myhostname dovecot: imap: Server shutting down. bytes=251/675 I tried to reload by initscript or sending -HUP manually to pid, dovecot is shutting down imapconnections and i think this is the reason for users to report this problems with some clients. This seems to be new with versions 2.x, i have some old 1.2.x dovecots running and cant find "Server shutting down" in their logs after reload. I have still potential to reduce reloads, but cant avoid them completely. Is there a workaround? Thanks, Hajo

[Dovecot] Difference between using auth_realms and setting up virtual mailboxes in postfix?
by Gab IIpop 16 Jul '13

16 Jul '13

Hi, there is a possibility in the future that I might have to support multiple domain names(but using the same IP address). Postfix has something called 'virtual mailboxes' to help handle this. But I also noticed that dovecot has a setting "auth_realms" where I can specify domains separated by a space. What is the relationship between the two?

[Dovecot] mail not reject when the mailbox is full (Dovecot-LDAP-Imap_quota)
by Victor Oñate 16 Jul '13

16 Jul '13

Hello List. Currently I have configured the share of users through the LDAP query as shown #dovecot.conf protocol imap { mail_plugins = quota imap_quota } plugin { quota = dirsize } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } #dovecot-ldap.conf auth_bind = yes ldap_version = 3 base = dc=XXX,dc=YY,dc=ZZ deref = never scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mail=Maildir,mailQuotaSize=quota_rule=*:storage=%$ user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid pass_filter = (&(objectClass=posixAccount)(uid=%u)) Additionally in thunderbird customers have the plug so they can see the share. This works perfect! However, when the mailbox exceeds 100% users continue to receive mail which makes the risk set allocated disk space, the idea is that when full the mail reject with a message "mailbox XXX full" . As always appreciate the ideas. Victor Oñate

[Dovecot] Proxying improvements in v2.1.2
by Timo Sirainen 16 Jul '13

16 Jul '13

I just committed a couple of features that will make life easier for some types of proxying setups: 1. IMAP proxying has already for a while supported sending local/remote IP/port to backend server, which can use it for logging and other purposes. I've now implemented this for POP3 as well, although only the remote IP/port is forwarded, not local IP/port. I implemented this also for LMTP in v2.2 tree, but haven't bothered to backport that change. Both POP3 and LMTP uses XCLIENT command that is compatible to Postfix's (XCLIENT ADDR=1.2.3.4 PORT=110). 2. proxy_maybe=yes + host=host.example.com actually works now. As long as host.example.com DNS lookup returns one IP that belongs to the current server the proxying is skipped. 3. auth_proxy_self = 1.2.3.4 setting means that if proxy_maybe=yes and host=1.2.3.4 then Dovecot assumes that this is a local login and won't proxy it, even if 1.2.3.4 isn't the actual local IP. This can be helpful if the host field contains load balancer's IP address instead of the server's. You can add more than one IP (space separated) and of course everything related to this works just as well with hostnames as with IPs (even when hostname expands to multiple IPs).

It means I'm not working in a normal environment, and don't (necessarily) have the normal range of tools available (or the most up to date version of those tools). It seems that 2.0.21 works (at least, as far as I've tested), but 2.1.17 and 2.2.4 won't start up their child services. I've got the source code for all three from http://www.dovecot.org/download.html, and, for experimental purposes, I'm configuring with: ./configure --prefix=/opt The configure script ends by reporting: Install prefix . : /opt File offsets ... : 64bit I/O polling .... : epoll I/O notifys .... : inotify SSL ............ : yes (OpenSSL) GSSAPI ......... : no passdbs ........ : static passwd passwd-file shadow checkpassword : -pam -bsdauth -sia -ldap -sql -vpopmail userdbs ........ : static prefetch passwd passwd-file checkpassword nss : -ldap -sql -vpopmail SQL drivers .... : : -pgsql -mysql -sqlite The dovecot.conf I'm using, at the moment, is the absolute minimal to fire things up: protocols = imap listen = * ssl_cert = </opt/etc/ssl/certs/dovecot.pem ssl_key = </opt/etc/ssl/private/dovecot.pem dovecot -n is happy, and reports those four lines back to me. When I start this up, I get, in /var/log/messages file: Jul 10 10:09:28 QNAP mail.info dovecot: master: Dovecot v2.0.21 starting up (core dumps disabled) and ps shows: [admin@qnap dovecot]# ps -ef | grep dovecot admin 11478 1 0 10:09 ? 00:00:00 /opt/sbin/dovecot dovecot 11479 11478 0 10:09 ? 00:00:00 dovecot/anvil admin 11480 11478 0 10:09 ? 00:00:00 dovecot/log admin 11482 11478 0 10:09 ? 00:00:00 dovecot/config admin 11525 455 0 10:10 pts/5 00:00:00 grep dovecot All is right with the world! Well, until I try to use dovecot properly, at which point I'll need a full configuration. But it's alright so far! :) However, if I go through the same routine with Dovecot 2.1.17, I get the appropriate message in messages: Jul 10 10:12:45 QNAP mail.info dovecot: master: Dovecot v2.1.17 starting up (core dumps disabled) But this time, ps shows: [admin@qnap dovecot-2.1.17]# ps -ef | grep dovecot admin 15259 1 0 10:12 ? 00:00:00 /opt/sbin/dovecot admin 15294 455 0 10:12 pts/5 00:00:00 grep dovecot and the child services don't seem to have started. This is born out by the fact that no network connections work: they stall, and then eventually time out (telnet localhost 143 produces no output at all, until I disconnect it). Even dovecot stop has trouble, taking several seconds before it returns me to the prompt, and *not* killing the existing process. dovecot -n is still happy however (and in a full configuration, components which don't require the services seem to work properly, such as dovecot-lda, if it doesn't require auth). I'm not sure that I need those newer versions of dovecot, so I'll get back to version 2.0 for now. But I'd certainly like the option, and imagine that somebody else might care as to what the problem is! -- Tommy Wareing

[Dovecot] trying to configre dovecot
by Gene Heskett 15 Jul '13

15 Jul '13

Hi all; Thinking I'd like to have a bit of security, I followed the example for dovecot from allgoodthings.org Guessing between the lines I made a few substitutions to localize it for me, but when I run the line to dump the configs, the output is very short because I do not have the *.pem files. Where can a usable set of these ssl 'keyfiles' be obtained? Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

[Dovecot] User login for SMTP but not for IMAP/POP?
by Martin 15 Jul '13

15 Jul '13

Hello everybody, I have a question, though I'm not sure if it's a matter of dovecot or postfix. Or if it's even possible to do at all. If I understand it correctly, SMTP authentification is done via SASL. When a user wants to login Postfix queries an external user database (dovecot). Therefore the SMTP-users are identical to the IMAP/POP-users. I want to achieve the following: I want some user credentials (username&password) for a user that is able to login via SMTP, but who doesn't have a mailbox and therefore shouldn't be able to login via IMAP/POP. Is this even possible? How can it be achieved? Or: does this behaviour have a special name, which I can google for? Regards, Martin

[Dovecot] login_trusted_networks from webmail ?
by Jan-Frode Myklebust 15 Jul '13

15 Jul '13

I'd like to get the IP-address of the webmail-klient logged in my maillog (for being compliant with coming data retention policies). I've noticed that with login_trusted_networks pointing at my dovecot directors, we get rip=client-ip logged on the backends. How is the proxy providing this to the dovecot backends? Anybody know what magic we need to implement in our webmail-solution to be able to forward the webmail-client-ip and have it logged as rip= in dovecot? I belive it will be enough to have it logged as rip= on the directors, maybe not needed to be forwarded all the way to the backends (but that would be nice as well). -jf

[Dovecot] new user questions
by Gene Heskett 14 Jul '13

14 Jul '13

Greetings; Trying to follow along with the wiki2 setup instructions and thought I'd hit a snag with the first "send me a mail" snippet as it took several minutes to arrive, so I assume that somehow procmail was involved in the delivery and my procmail runs mail thought a whole bunch of checks before finally handing it off to a mailfile as /var/mail/gene. Then the next script seems to only try whats in my home dir, and of course doesn't find it as neither exists, yet... I assume that is because dovecot needs a kill -HUP. But I am not familiar with that, so how is it done, and as what user, me, or root, on a ubuntu 12.04.2 LTS install? Thanks.

[Dovecot] Mail replication ... totally confused !
by HL 13 Jul '13

13 Jul '13

Hello, I am totally confused configuring replication in dovecot. In my case I have 2 servers instead of running rsync as a daemon which takes a lot of time I would like SERVER-A will be the master and SERVER-B will be the slave My users directly interact with server A, Server B stands as a mails backup only I've setup SERVER-B ( backup ) like that, NO SPECIAL CONF on master SERVER-A Is this ok ?? I Don't want to miss any mails Since this is a live server service aggregator { # give enough permissions for mail processes # fifo_listener replication-notify-fifo { user = vmail mode = 0600 } unix_listener replication-notify { user = vmail mode = 0600 } } service replicator { # start replication at startup # process_min_avail = 1 } service doveadm { # if you're using a single virtual user, set this to start ssh as vmail # (not root) # user = vmail } service config { # needed to grant access to /var/run/dovecot/config for service doveadm # unix_listener config { user = vmail } } dsync_remote_cmd = ssh -p 1234 -l%{login} %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} plugin { mail_replica = remote:vmail@master-server-a.tld replication_full_sync_interval = 1 hours }

[Dovecot] Ambiguous behavior with prefetch database?
by Axel Luttgens 13 Jul '13

13 Jul '13

Hello, Let's say dovecot.conf contains: mail_uid = dovemailer mail_gid = dovemailer mail_home = /some/path/%n mail_location = mbox:~/mboxes:INBOX=~/mboxes/inbox and that the password database query is of the form: password_query = \ SELECT \ passwd AS password, \ nickname AS user, \ mail_home AS userdb_home, \ mail_location AS userdb_mail, \ WHERE \ ... The database initially comes with NULL for both mail_home and mail_location, the goal being to be able to progressively replace legacy settings. With the above, one gets such entries in the logs upon a pop or imap connection: auth-worker(11262): Debug: auth(u12345678,127.0.0.1): username changed u12345678 -> john.doe auth: Debug: auth(u12345678,127.0.0.1,<dsNsasbgRQB/AAAB>): username changed u12345678 -> john.doe [...] auth: Debug: prefetch(john.doe,127.0.0.1,<dsNsasbgRQB/AAAB>): passdb didn't return userdb entries, trying the next userdb and, of course, the userdb_query fails since it isn't supposed to be invoked under such circumstances. Of course, the userdb_query could be adapted so as to handle pop/imap connections in addition to say, lmtp or doveadm connections, but this would anyway raise the question: why bother with a prefetch database setup? In fact, it seems that the problem comes from the fact that the password_query returns NULL values (i.e. "do not override dovecot.conf settings") for all userdb_xxx settings even if, technically speaking, it returns such columns. A slight yet somewhat silly modification of the password_query, such as this one: password_query = \ SELECT \ passwd AS password, \ nickname AS user, \ 'dovemailer' AS userdb_uid, \ mail_home AS userdb_home, \ mail_location AS userdb_mail, \ WHERE \ ... indeed seems to bring back all the expected behavior: now, the "passdb returns userdb entries" and, for example, the config's mail_home expands to the expected value /some/path/john.doe. Could it be that the case "userdb_xxx columns returned, even if all with NULL values" has been somehow overlooked in the code? Or am I erring with my interpetation of all those matters? TIA, Axel

[Dovecot] A sqlite-based quota dict
by Axel Luttgens 13 Jul '13

13 Jul '13

Hello, While experimenting with the sqlite backend, I noticed a big vacuum wrt its use for a quota dict. This is thus an opportunity to share a solution I managed to devise after some trials and errors and a (very quick and unscientific) look at the code. And also the opportunity to ask the community to check for possible flaws. Yes, nothing comes for free... ;-) TIA, Axel This is the SQL for creating the database or for adding needed table/trigger to an existing database (with many comments and few "active" lines): CREATE TABLE quota ( -- We will assume that, in the case of a sqlite DB (and probably a pgsql DB -- as well), Dovecot will *always* act along these lines: -- In case of a "row creation": -- INSERT INTO quota (subject, byte_count) -- VALUES (<some id>, <byte count>); -- INSERT INTO quota (subject, message_count) -- VALUES (<some id>, <msg count>); -- In case of a recalculation: -- UPDATE quota -- SET byte_count = byte_count + <byte count diff>, -- message_count = message_count + <msg count diff> -- WHERE subject = <some id>; -- In case of a row deletion: -- DELETE FROM quota -- WHERE subject = <some id>; -- For example, a "doveadm quota recalc" may first delete the relevant row -- if it exists, then (re-)create it. -- Clearly, the "row creation" case is a bit problematic, hence the need for -- a trigger. -- An id for the entity subjected to a quota (a user/mailbox, a domain...). subject TEXT PRIMARY KEY NOT NULL, -- The entity's size, expressed as a storage space use and as a message -- count. -- Note the NULL defaults: they allow to simplify the trigger's logics. byte_count INTEGER DEFAULT NULL, message_count INTEGER DEFAULT NULL ); CREATE TRIGGER quota_insert BEFORE INSERT ON quota FOR EACH ROW BEGIN -- If there's a row to update, that's because the first INSERT of the "row -- creation" has been performed. -- (this UPDATE could probably be simplified if the insertion order, -- byte_count then message_count, was guaranteed; anyway, since the "row -- creation" operation shouldn't be very frequent, we may afford a slight -- inefficiency). UPDATE quota SET byte_count = CASE WHEN NEW.byte_count ISNULL THEN byte_count ELSE NEW.byte_count END, message_count = CASE WHEN NEW.message_count ISNULL THEN message_count ELSE NEW.message_count END WHERE subject = NEW.subject; -- In which case we may ignore that second (current) INSERT, since the -- previously inserted row has just been updated with the value coming -- from the current INSERT statement. SELECT raise(IGNORE) WHERE EXISTS (SELECT * FROM quota WHERE subject = NEW.subject); END; The corresponding dict configuration being thus supposed to be similar to this one: connect = /path/to/database map { pattern = priv/quota/storage table = quota username_field = subject value_field = byte_count } map { pattern = priv/quota/messages table = quota username_field = subject value_field = message_count }

[Dovecot] Dovecot Virtual Folders... could these be managed by a/the Client?
by Charles Marcus 12 Jul '13

12 Jul '13

Hi all/Timo, I was thinking about Thunderbirds ability to create Virtual folders allowing you to have many different views of your messages... The downside though, is you only see these in Thunderbird. I know that dovecot supports server side virtual folders: http://wiki2.dovecot.org/Plugins/Virtual But I'm wondering about the possibility to manage these from the client side... For example, would it be possible to create an extension in Thunderbird that allowed the user to manage these (create, edit the filters for, delete, rename, etc)? Thanks, -- Best regards, Charles

[Dovecot] (no subject)
by Gab IIpop 12 Jul '13

12 Jul '13

>From the documentation, virtual users seem like a good idea if you plan on having a lot of users. Although I'm wondering about the following: What other benefits/consequences are there to using virtual over system users and vice versa? Will virtual users have the same protection as system users (system users would use linux permissions, which is pretty secure)? How easy will it be to switch from using system users to virtual users or vice versa?

[Dovecot] avoid log message when using nagios check
by lluis 12 Jul '13

12 Jul '13

Hello, I'm using a nagios check to monitor dovecot status, since dovecot v2 I see those syslog messages on every nagios check: pop3-login: Aborted login (no auth attempts in 0 secs) imap-login: Aborted login (no auth attempts in 0 secs) I tried to avoid those messages sending a logout string: check_imap -H localhost -e 'OK' -s 'a logout' check_pop -H localhost -e 'OK' -s 'quit' but now I get imap-login: Disconnected (no auth attempts in 0 secs) pop3-login: Disconnected (no auth attempts in 0 secs) what can I do to avoid a log message on every nagios check? thanks!

[Dovecot] getting quota error when accessing private namespace
by Andreas Oster 12 Jul '13

12 Jul '13

Hi all, I have run into a problem which I cannot find a solution for. I have created an additional private namespace with the following commands in dovecot.conf : namespace { disabled = no hidden = no ignore_on_failure = no inbox = no list = children location = maildir:/var/vmail/archives/%Ln/Maildir mailbox "archived mails" { auto = subscribe driver = special_use = \Archive } prefix = Archives/ separator = / subscriptions = yes type = private } plugin { quota = maildir:User quota:ns= quota2 = maildir:Archives quota:ns=Archives/ quota2_rule = *:storage=5G quota_rule = *:storage=1G quota_rule2 = Trash:storage=+200M } I can access the new namespace without any problems but every time a folder in this namespace is accessed, I get the following error messages in mail.err log: dovecot: imap(testuser): Error: quota: Unknown namespace: Archives/ dovecot: last message repeated 49 times Quota seems to work, though I have the feeling, that it only will be updated when closing and reopening the mail client, but this can also be a client issue. Quota for the INBOX is either taken from LDAP or, if there is no value defined in LDAP, will be assigned a quota of 1G The Archives/ namespace has a static quota of 5G for every user. Does anyone have idea how to get rid of these error messages ? Thank you for your kind help Andreas

[Dovecot] Multiple Folders Continually Auto-Created
by Cassidy Larson 12 Jul '13

12 Jul '13

I've had reports of a number of clients running Outlook 2011 on Mac where they have quite a few folders with the same name appended by multiple "1"s. So far I've only narrowed it down to Outlook 2011 on Mac. We've been in the process of migrating to sdbox on a new server from maildir using dsync backup. Example folder structure: INBOX INBOX 1 INBOX 1 1 INBOX 1 1 1 INBOX 1 1 1 1 INBOX 1 1 1 1 1 INBOX 1 1 1 1 1 1 INBOX 1 1 1 1 1 1 1 INBOX 1 1 1 1 1 1 1 1 INBOX 1 1 1 1 1 1 1 1 1 INBOX 1 1 1 1 1 1 1 1 1 1 Junk Junk 1 Junk 1 1 Junk 1 1 1 Junk 1 1 1 1 Junk 1 1 1 1 1 Junk 1 1 1 1 1 1 Junk 1 1 1 1 1 1 1 Junk 1 1 1 1 1 1 1 1 and so on for "Sent Messages", etc. Seems that the the default folders for these clients are getting created over and over again, each time with a new "1" at the end. Anybody else see this? I'm digging for a client I can troubleshoot with and reproduce with me watching. Thanks, -c

[Dovecot] SSL cert problem

Hi, I'm running a new dovecot 2.0.9 under Centos 6.4. I'm having an issue with SSL certificate not being accepted by the email client. I have my own CA and I have generated certificates for web usage without a problem.

[Dovecot] dsync/imapc migration question
by Gedalya 12 Jul '13

12 Jul '13

Doing an imapc migration with the pop3 migration plugin, using doveadm backup -R. I occasionally get the following output: dsync(user(a)domain.tld): Error: imapc(mail01.domain.tld:143): Server disconnected unexpectedly dsync(user(a)domain.tld): Error: imapc(mail01.domain.tld:143): Server disconnected unexpectedly dsync(user(a)domain.tld): Error: imapc(mail01.domain.tld:143): Server disconnected unexpectedly dsync(user(a)domain.tld): Warning: I/O leak: 0xb7648650 (line 1229, fd 10) dsync(user(a)domain.tld): Warning: I/O leak: 0xb7648650 (line 1229, fd 11) dsync(user(a)domain.tld): Warning: Timeout leak: 0xb76488b0 (line 1316) dsync(user(a)domain.tld): Warning: Timeout leak: 0xb76488b0 (line 1316) The source server is really crappy, no need to look at the dovecot side for causes. My question is: is it possible that the migration did complete successfully? Dovecot does seem to continue and it's kind of vague on what went wrong, and did it re-try. This operation can take several hours on large mailboxes so this question is really meaningful in my case. (I'd try with -D but it's really hard to reproduce this on demand). Thanks Gedalya

[Dovecot] Pigeonhole vacation auto-response not respecting "days" parameter
by Thomas Harold 11 Jul '13

11 Jul '13

This might be a PEBKAC on my end, but in our old server, "vacation" responses would only be sent back to an origin address once per day because we had ":days 1" in the rule. On the new server, even though we have ":days 1", pigeonhole is sending responses to every message, resulting in multiple vacation responses each day back to each origin address. The following was generated by Roundcube's web interface, it looks to be correct. ----------------------- require ["vacation"]; # rule:[vacation-reply] if allof (not header :contains "Subject" "[spam]", not exists "List-Unsubscribe") { vacation :days 1 :addresses ["email1(a)example.com","email2(a)example.com"] :subject "Out of office reply" text: I am currently out of the office July 11th and 12th, returning on July 15th. During this time I will have no access to email. Thank you. User So-And-So . ; } ----------------------- Interestingly, if I look at .dovecot.sieve.log, I see error messages like (except that the vacation responses are, in reality, being sent): error: msgid=<20130711134816.35B9A40335(a)mail.example.com>: failed to send vacation response to <originemail(a)example.com> (refer to server log for more information). And in the maillog: Jul 11 09:48:17 servername sendmail[28244]: r6BDmHem028244: SYSERR(UID1132): Who are you? Jul 11 09:48:17 servername sendmail[28244]: r6BDmHem028244: Authentication-Warning: servername .example.com: Unknown UID 1132 set sender to <> using -f Jul 11 09:48:17 servername sendmail[28244]: r6BDmHem028244: from=<>, size=725, class=-60, nrcpts=1, msgid=<dovecot-sieve-1373550497-202242-0(a)servername.example.com>, relay=Unknown UID 1132@localhost My guess at this point is that I've failed to configure pigeonhole and/or postfix's copy of the sendmail command properly so that it can create the "who I have send mail to recently" file.

The system hang, linux from scratch. I have changed the live kernel from linux-2.6.35.4 to linux-2.6.32.61 , to see if the fault still occurs.

[Dovecot] How to manipulate attachments with LDA?
by Piotr Szafarczyk - NetExpert 10 Jul '13

10 Jul '13

Hi All, I want to plug in a tool that will convert attachments somewhere into a mail delivery process (postfix->dovecot). I think deliver would be a good place to do it. Does it make sense? Could you direct me where I could read about how to do it please? Piotr Szafarczyk

[Dovecot] Have an issue with catch-all - Dovecot-lda andPostfix
by Joakim Ohlsson 10 Jul '13

10 Jul '13

Hi, I run dovecot version 2.1.7 and postfix 2.9.6. I'm using dovecot-lda as local delivery. I use virtual users and need to use catch-all for some of my domains. My problem when using catch-all is that I got a separate email for each recipient. As an example: If I send mail to: test1(a)test.org, test2, test3(a)test.org, test4(a)test.org and have a catch-all which will send this mail to test(a)test.org. In this example I get 4 mails in my test(a)test.org inbox and in TO: field in the header I have all this four recipients: TO: test1(a)test.org, test2, test3(a)test.org, test4(a)test.org. In my dovecot log: 2013-07-10 13:49:25 lda(test(a)test.org): Debug: Destination address: test(a)test.org (source: user@hostname) 2013-07-10 13:49:25 lda(test(a)test.org: Info: msgid=<20130710114924.DBA3F9FA8D(a)mail2.test.org>: saved mail to INBOX 2013-07-10 13:49:25 lda(test(a)test.org): Info: msgid=<20130710114924.DBA3F9FA8D(a)mail2.test.org>: saved mail to INBOX 2013-07-10 13:49:25 lda(test(a)test.org): Info: msgid=<20130710114924.DBA3F9FA8D(a)mail2.test.org>: saved mail to INBOX 2013-07-10 13:49:25 lda(test(a)test.org): Info: msgid=<20130710114924.DBA3F9FA8D(a)mail2.test.org>: saved mail to INBOX My question is if it's possible to receive just one mail instead of four? If I send the mail via Spamassassin I'll just receive one mail to test(a)test.org with TO: test1(a)test.org, test2, test3(a)test.org, test4(a)test.org in the header. Thanks in advance Br Joakim # dovecot -n:

Here is snip from dovecot.log: 2013-06-25T23:06:47.824321+02:00 meteor dovecot: imap-login: Login: user=<marcin(a)mejor.pl>, method=PLAIN, rip=2001:470:1f0b:1ab3:1bc:3b24:d355:b142, lip=2001:470:1f15:1b61::2, mpid=44562, TLS, session=<PaQ86ADgegAgAQRwHwsaswG8OyTTVbFC> 2013-06-25T23:06:47.827616+02:00 meteor dovecot: imap(marcin(a)mejor.pl) <PaQ86ADgegAgAQRwHwsaswG8OyTTVbFC>: Warning: autocreate plugin is deprecated, use mailbox { auto } setting instead 2013-06-25T23:06:47.830425+02:00 meteor dovecot: imap(marcin(a)mejor.pl) <PaQ86ADgegAgAQRwHwsaswG8OyTTVbFC>: Fatal: master: service(imap): child 44562 killed with signal 11 (core dumped) Here is bt created using gdb: Reading symbols from /usr/libexec/dovecot/imap...Reading symbols from /usr/lib64/debug/usr/libexec/dovecot/imap.debug...done. done.

[Dovecot] Dovecot SLOW in imaptest without any apparent reason

Hello, I'm migrating a mail server from a centos 5 cluster architecture to a centos 6 cluster architecture. The new cluster involves faster machines then the old cluster, and a virtual machine. I use dovecot-2.0.9-5.el6.x86_64, while the old cluster uses dovecot-2.0.1-1_118.el5. Tha mail server uses mysql for the users database, and a local ldap for authentication. The storage is also much faster in the new cluster: OLD SERVER: date; dd if=/dev/zero of=/cl/prova.bin bs=102400 count=10240; sync; date Wed Jun 26 15:43:53 CEST 2013 10240+0 records in 10240+0 records out 1048576000 bytes (1.0 GB) copied, 30.0202 seconds, 34.9 MB/s Wed Jun 26 15:44:28 CEST 2013 --> 1GB / 35 secs = about 29.25 MB/sec NEW SERVER: date; dd if=/dev/zero of=/cl/prova.bin bs=102400 count=102400; sync; date mar 25 giu 2013, 15.46.36, CEST 102400+0 records in 102400+0 records out 10485760000 bytes (10 GB) copied, 62,5143 s, 168 MB/s mar 25 giu 2013, 15.48.33, CEST [root@eta ~]# ---> 10GB / 117secs = about 85.47MB/sec An 'ls -l' in the user direcotry is also much faster, when the ldap/sssd cache is populated: OLD SERVER: real 0m8.540s user 0m1.229s sys 0m0.699s NEW SERER: real 0m3.938s user 0m0.250s sys 0m0.151s But my imaptest is much slower: ./imaptest user=XXXXXXX pass=XXXXXXX secs=120 seed=123 mbox=./dovecot-crlf OLD SERVER: Totals: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 100% 30% 5% 1122 559 547 1121 1121 1568 136 900 1121 1121 2244 NEW SERVER Totals: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 100% 30% 5% 390 210 185 389 389 589 49 320 389 389 780 The configuration is exactly the same in the 2 clusters, that is: ----------- # 2.0.1: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-348.3.1.el5 x86_64 Red Hat Enterprise Linux Server release 5.9 (Tikanga) xfs auth_cache_size = 1024 auth_cache_ttl = 21600 s auth_debug = yes auth_debug_passwords = yes auth_master_user_separator = * auth_mechanisms = plain login auth_socket_path = /var/run/dovecot/auth-userdb auth_verbose = yes base_dir = /var/run/dovecot/ disable_plaintext_auth = no hostname = mail.unimore.it info_log_path = /var/log/dovecot.log lda_mailbox_autocreate = yes log_path = /var/log/dovecot.log mail_debug = yes mail_location = maildir:/cl/mail/vhosts/sms.unimo.it/%Ln/Maildir mail_plugins = $mail_plugins quota mailbox_idle_check_interval = 60 s mbox_write_locks = fcntl namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = /usr/local/etc/dovecot.masterusers driver = passwd-file master = yes } passdb { args = dovecot driver = pam } plugin { quota = maildir:User quota quota_exceeded_message = Quota exceeded (mailbox is full) quota_rule = *:storage=200MB quota_rule2 = *:messages=100000 quota_rule3 = INBOX.Trash:storage=+100M quota_warning = storage=90%% quota-warning 90 %u quota_warning2 = storage=85%% quota-warning 85 %u quota_warning3 = messages=95%% quota-warning 95 %u quota_warning4 = messages=80%% quota-warning 80 %u setting_name = quota } postmaster_address = postmaster(a)unimore.it quota_full_tempfail = yes service anvil { client_limit = 199999 process_limit = 1 } service auth { client_limit = 21224 unix_listener auth-userdb { mode = 0600 user = vmail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 } process_limit = 10000 } service imap { process_limit = 10000 } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 } } service pop3 { process_limit = 1024 } service quota-warning { executable = script /usr/local/bin/quota-warning.sh unix_listener quota-warning { group = vmail user = vmail } user = dovecot } ssl_ca = </etc/pki/tls/certs/ca_unimore_tcs.pem ssl_cert = </etc/pki/tls/certs/mailposta1.pem ssl_key = </etc/pki/tls/certs/mailposta1.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } verbose_ssl = yes protocol lda { mail_plugins = $mail_plugins quota } protocol imap { mail_plugins = $mail_plugins } protocol pop3 { mail_plugins = $mail_plugins quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } ----------- Is anyone able to tell me what I have to check? thanks in advance Fabio Ferrari
