[Dovecot] fts, solr, and client support
by Kelsey Cummings 04 Sep '10

04 Sep '10

I've been playing around with the fts plugins and currently have solr up and running. While the initial indexing time is pretty rough, the search performance is impressive. I've run into a problem though- so far as I can tell, thunderbird (and most other popular clients?) won't actually take advantage of it. Even using thunderbird's advanced search and checking the 'run serach on server' box doesn't push the search to the server. If most popular clients don't support it, there doesn't seem much point in setting it up; which is a shame, solr beats the snot out of the built in search for thunderbird. That said, is anyone running any of the fts plugins in a large scale environment? If so, what kind of scaling issues do you see? How do the search servers compare hardware wise to users count/spool size? -- Kelsey Cummings - kgc(a)corp.sonic.net sonic.net, inc.

Newbie alert! Dovecot 2.0rc3 I've got autosubscribe working very well, but I need to make it dependent on the domain - e.g. domain example.com will have folders (a,b,c), while domain example2.com will have (d,e,f). Any hints on how to achieve that? /Per Jessen, Zürich

[Dovecot] Best way to migrate from qmail-ldap's autoreply?
by Attila Nagy 03 Sep '10

03 Sep '10

Hi, qmail-ldap uses four LDAP attributes for handling autoreplies in qmail-local: - deliverymode (to see whether the autoreply should be send) - mailreplytext, which is a base64 encoded multiline string* - mailreplystart and mailreplystop, unix dates I'm wondering how this could be handled with Dovecot (2.0) in the most easier way. All I could find out so far: - patching the code - writing a plugin (it it possible to get these LDAP attributes in the LMTPd with a single userdb-lookup and get it from the plugin during a new mail event? Any examples?) - conditionally provide these values to a sieve script and process them accordingly (the base64 string and maybe the dates seem to be hard for the first glimpse) the mad stuff: - using an LD_PRELOAD library, which emulates per user sieve scripts according to LDAP lookups (gives a lot more flexibility) - an LMTP proxy/server, which does all this and forwards the traffic to the Dovecot LMTPd/deliver process * a sample mailreplytext looks like this: '''%HEADER% Content-type: text/plain; charset="utf-8" távol vagyok''' (of course this is in UTF-8).

[Dovecot] Maybe wrong quota recalculation behaviour on overquota delivery try
by Luca Palazzo 03 Sep '10

03 Sep '10

Hi all, we are experencing some, may be strange, slowness in our dovecot/postfix mail system. We have three dovecot 2.0.1 server with LMTP, POP3 and IMAP enabled. Three shared OCFS2 filesystem are used for mail storage. We have too a load balancer based on dovecot director in front of these three server. Our SMTP cluster receives mail and send by LMTP to load balancer. Everything work flowless, but sometime, under heavy load, three server slow down a lot. Our mail gateway logs a lot of: status=deferred (host 10.194.1.20[10.194.1.20] said: 451 4.4.0 Remote server not answering (DATA output timeout) IP 10.194.1.20 is dovecot director. Looking at mbox servers log nothing seem to happen, but stracing lmtp process we can see stat system calls to all Maildir files, as if dovecot was recalculating quota and regenerating maildirsize file. It happens always when LMTP tries to deliver a mail to an overquota account. Is this possible and right? How can we look deeper in system to have more information? Best regards Luca PS: dovecot configuration for maildir servers is: # 2.0.1: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686-bigmem i686 Debian 5.0.5 auth_master_user_separator = * auth_verbose = yes disable_plaintext_auth = no mail_location = maildir:~/Maildir mail_plugins = $mail_plugins notify mail_log quota managesieve_notify_capability = mailto managesieve_sieve_capability = comparator-i;octet comparator-i;ascii-casemap fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date spamtest spamtestplus virustest passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid from size quota = maildir:User quota quota_warning = storage=95%% quota-warning.sh 95 %u quota_warning2 = storage=80%% quota-warning.sh 80 %u sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_global_dir = /etc/dovecot/sieve/global/ sieve_global_path = /etc/dovecot/sieve/default.sieve } protocols = imap pop3 lmtp sieve service auth { unix_listener auth-userdb { group = dovecot mode = 0600 user = dovecot } } service director { inet_listener { port = 8100 } } service lmtp { inet_listener lmtp { address = 10.194.1.31 127.0.0.1 ::1 port = 24 } } service managesieve-login { inet_listener sieve { address = 10.194.1.31 127.0.0.1 ::1 port = 4190 } process_min_avail = 0 service_count = 1 } service quota-warning { executable = script /virtual/shared/quota-warning.sh unix_listener quota-warning { user = vmail } user = dovecot } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } verbose_proctitle = yes protocol lmtp { mail_plugins = $mail_plugins quota sieve } protocol lda { mail_plugins = $mail_plugins quota } protocol imap { mail_plugins = $mail_plugins quota imap_quota } protocol pop3 { mail_plugins = $mail_plugins quota }

[Dovecot] minor director issues
by Cor Bosman 03 Sep '10

03 Sep '10

I noticed 2 minor things with the director. 1) if I start 2 directors, but in 1 of them I dont add the other as a director_servers, they both start spamming the logfiles really really fast. It seems there is no backoff mechanism in the protocol between directors. 2) user mail server ip expire time cor 194.109.26.171 2010-09-02 14:32:13 <unknown> 194.109.26.172 2010-09-02 14:33:13 Why does it say 'unknown'? That session is active, im manually logged in with telnet, issued a login and a select inbox. The first one is a normal mail client login. Regards, Cor

[Dovecot] Suggested location for single-dbox
by William Blunn 03 Sep '10

03 Sep '10

I've updated http://wiki2.dovecot.org/MailLocation regarding a typical mail_location entry for dbox. Previously it said: mail_location = dbox:~/dbox but of course "dbox" is now the old name for "sdbox", so the example should be updated to say "sdbox" and there might/ought also to be an example for "mdbox". In http://wiki2.dovecot.org/MailboxFormat/dbox the example mail_location for mdbox is given as "mdbox:~/mdbox", so I have followed that for "MailLocation". So I have changed it to say # single-dbox mail_location = sdbox:~/dbox or: # multi-dbox mail_location = mdbox:~/mdbox I didn't know whether to change the directory for sdbox to "~/sdbox" or to leave it as it is. For the time being I have left it at "~/dbox" --- following the example given should allow new installations of Dovecot 2 to be able to read any existing single-dbox data which used the historically-suggested "~/dbox" location, whilst at the same time avoiding using the old mailbox format name of "dbox".

[Dovecot] My "%%" variables in the namespace settings do not appear to be expanding.
by Kenneth Cope 02 Sep '10

02 Sep '10

Hello, I've been using the dovecot 1.2.x branch server software for a while now. With the advent of the 2.0.x branch going 'stable' I decided to attempt a migration and make use of some of the features that I've not needed before. One of these is the shared folder/namespace feature. No luck. I've hit a wall and can not determine the problem. At the moment it looks like a bug to me, but it may well be that I'm missing some related configuration, or file permission. I can not get the %% variable expansion in a namespace to work. What I end up with, on an IMAP connection is a directory named, for instance, '%h'. The same goes for any of the %% variables used at this point. My current set-up is 'not' the same as the current setup and I'm using virtual users that are not 'live' on the current system. I would really appreciate it if someone could cast an eye over my config and let me know if I've missed something obvious. Thanks.

Hello All I am trying to compile and use pigeonhole and I am experiencing the same exact problem that is stated here: http://dovecot.org/pipermail/dovecot/2010-August/051859.htm [root@mongo dovecot-2.0-pigeonhole-build]# ldd /usr/lib/dovecot/managesieve-login linux-gate.so.1 => (0xb777e000) libdovecot-login.so.0 => not found libdovecot.so.0 => not found libc.so.6 => /lib/libc.so.6 (0xb7622000) /lib/ld-linux.so.2 (0xb777f000) lt does not seem as if -Wl,-rpath -Wl,/usr/local/lib/dovecot is being appended to gcc -std=gnu99 -march=i686 -mtune=generic -O2 -pipe -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -Wstrict-aliasing=2 -o managesieve-login client.o client-authenticate.o managesieve-login-settings.o managesieve-proxy.o ../../src/lib-managesieve/libmanagesieve.a -ldovecot-login -L/usr/lib/dovecot -ldovecot -lrt ^^See: http://dovecot.org/pipermail/dovecot/2010-August/051907.html However, my lack of programming knowledge and skills prohibit me from trying to fix this myself. I am hoping some kind soul would be nice enough to fix it. Thank you!

[Dovecot] Dovecot - some more optimisations
by Len7hir 02 Sep '10

02 Sep '10

I did some more optimisation. Most performance hit in Dovecot do "for loop" in string operations. In one case (in message-parser.c) "for loop" has another "for" inside with the same variable used as iterator. This case is very hard to optimise by compiler. I do changes only in top functions listed in oprofile. Maybe I do more in future. Code was analysed and tested but it's hard to generate all cases. It's working well in production server (I'm monitoring). In istream-crlf.c I've changed one thing. When destination buffer is full after '\r' addition (to dest), It didn't skip '\n' in source buffer. I think this was buggy in earlier code, and '\n' was skipped (this piece of code is used very rare). Please check this out. This can help in huge e-mail systems :P And another problem. Why You use safe_memset instead of memset? Now this function have the largest impact in Dovecot performance. Another on list is t_push. Regards, Len7hir

[Dovecot] Passdb filter question - LDAP.
by Lauro Costa G. Borges 01 Sep '10

01 Sep '10

dovecot 1:1.2.9-1ubuntu6.1 ---- I don't know if I can solve this problem with Dovecot, or if it's an LDAP matter. I'm authenticating users with saslauthd/LDAP, and using Dovecot LDA. ---- dovecot.conf passdb ldap { args = /etc/dovecot/dovecot-ldap-passdb.conf } userdb prefetch { } # The userdb below is used only by deliver. userdb ldap { args = /etc/dovecot/dovecot-ldap-userdb.conf } ----- ----- dovecot-ldap-passdb.conf search base is dc=example,dc=org pass_filter = (&(objectclass=brPerson)(objectclass=inetOrgPerson)(mail=%u)) pass_attrs = userPassword=password,%u=user ----- ----- dovecot-ldap-userdb.conf search base is ou=%d,ou=mail,ou=services,dc=example,dc=org user_filter = (&(objectclass=nisMailAlias)(cn=%n)) user_attrs = rfc822MailMember=user,EmailQuota=quota_rule=*:storage=%$M ----- Here is how the LDAP tree is: ou=mail,ou=services,dc=example,dc=org ou=subdomain1.example.org,ou=mail,ou=services,dc=example,dc=org example entry under "ou=subdomain1.example.org" --- dn: cn=userfoo,ou=subdomain1,ou=mail,ou=services,dc=example,dc=org cn: userfoo edupersonprincipalname: WEMHVDEA-FUAOBAAA(a)example.org (some sort of unique identifier) emailquota: 512 objectclass: eduPerson objectclass: nisMailAlias rfc822mailmember: userfoo(a)subdomain1.example.org --- ou=people,dc=example,dc=org dn: uid=29859085900(a)example.org,ou=people,dc=example,dc=org uid: 29859085900(a)example.org eduPersonPrincipalName: WEMHVDEA-FUAOBAAA(a)example.org userPassword: {MD5}6ZoYxCjLONXyYIU2eJIuAw== objectClass: person objectClass: inetOrgPerson objectClass: eduPerson mail: 29859085900(a)example.org mail: userf(a)director.example.org mail: userfoo(a)dptoxyz.example.org mail: userfoo(a)subdomain1.example.org When delivering email, it must search under "services", for the proper "rfc822mailmember", which is the mailbox. When authenticating, there's where my problem is, I can't have ALL user e-mails under "ou=people", maybe just 1, so I need to search under "ou=services", there I have all user email addresses, and by using "edupersonPrincipalName", I want to point to the right location under "ou=people", where I have the user password. edupersonPrincipalName is the attribute present under "ou=services" and "ou=people" that links the entries. I tried to do it by changing passdb filter file, like this: pass_filter = (&(objectclass=eduPerson)(mail=%u)) pass_attrs = userPassword=userdb_password,eduPersonPrincipalName=userdb_user It works, but changes the username to the value of "edupersonprincipalname", and this changes the mailbox name. Dovecot accesses the wrong mailbox then (something like 29859085900(a)example.org) * My question is: is it possible to change the passdb filter, so it searches for somemail(a)sub1.example.org (under ou=services), then it gets the value of "edupersonprincipalname" (the unique identifier, present under "services" and "people"), and with that value, it looks under "people" the person with that identifier and validates the password. It would be a filter inside a filter, sort of. thanks, and sorry if this is a little offtopic. ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

[Dovecot] Filtering virtual mailbox using other virtual mailbox?
by Giovanni Giorgi 01 Sep '10

01 Sep '10

Hi All, my name is Giovanni and I am new to dovecot. I have installed version 2.0 the past week and I find it very powerful. I have started to play with the virtual mailbox plugin. I was unable to do a virtual mailbox filtering out the contents of other mailbox, for instance I have a virtual/spam mailbox which filter out all the spam thanks to spamassassin. This mailbox is virtual, its description is INBOX -Trash -Trash/* -Junk subject SPAM I'd like to do a simple virtual/ham mbox using this dovecot-virtual INBOX -virtual/spam to: jj(a)gioorgi.com but it seems not working. it does not filter the spam. It is possible to do such thing, or I am trying to do something not possible at all? Thank you (\__/) (='.'=) (")_(") Giovanni Giorgi jj(a)gioorgi.com

[Dovecot] Help with Public Folder Configuration
by Joy 01 Sep '10

01 Sep '10

Dear All, I am trying to use Public Folder feature of dovecot but having some confusion with the configuration part as well as understanding the same. Here is output of doveconf -n which i think required to help me - mail_location = maildir:~/Maildir namespace { inbox = yes location = prefix = separator = . type = private } namespace { list = children location = maildir:/var/mail/public prefix = Public. separator = . subscriptions = no type = public } plugin { acl = vfile:/usr/local/dovecot/dovecot-acl/acl } after making this configuration i also created subfolder inside /var/mail/public which looks like following:- mail1:~# less /var/mail/public/ dovecot-acl-list .Public/ mail1:~# less /var/mail/public/.Public/Maildir/ cur/ new/ tmp/ I have changed default permission to [ chown -R vmail:vmail /var/mail ] on base public folder. Now I am able to see the public folder from webmail as well as from thunderbird but no display for .Public folder. I am expecting that .Public folder will be visible to all but no one will be allowed to delete and make any change in that folder, I am also using global ACL in my configuration. Please let me know what i am doing wrong because not getting any error in log, Correct me if i am understanding wrong. Thanks
