[Dovecot] AntiSpam Plugin
by Leander S. 04 Aug '10

04 Aug '10

P.S. I just tried it with 1.2.13 as well - still the same issue. Am I doing something wrong, or is this really a bug now!? Best Regards Leander S. Hi, Has anyone got the chance to get this running? I'm permanently getting this Serverbug error ... ;( *"[SERVERBUG] failed to send email"* ... This happens when I try to drag&drop mails from one to the other folder within a IMAP-session. What version of Dovecot must I have to get this plugin working? Or will it generally be broken in upcoming new releases of Dovecot? Best Regards Leander S.

[Dovecot] problem with mail_full_filesystem_access = yes
by Ladislav Pašek 04 Aug '10

04 Aug '10

Hello, I have configured Dovecot 1.2.12 with Postfix 2.6.5 and everything is working fine. But tomorrow I wanted to run IMAP ALCs and from log I found that this plugin is conflicting with parameter mail_full_filesystem_access = yes in my config. But when I set mail_full_filesystem_access = no it stops authorization for postfix with this message: <pasek(a)valbek.cz>: Command died with signal 11: "/usr/libexec/dovecot/deliver" Does anybody know what could be wrong in my config? I've spend a night with it but without success. You can see my Dovecot here: http://www.volny.cz/vykupitel/Pictures/mail/dovecot.conf http://www.volny.cz/vykupitel/Pictures/mail/dovecot-ldap.conf and Postfix here: http://www.volny.cz/vykupitel/Pictures/mail/main.cf http://www.volny.cz/vykupitel/Pictures/mail/master.cf http://www.volny.cz/vykupitel/Pictures/mail/ldap-users.cf http://www.volny.cz/vykupitel/Pictures/mail/ldap-groups.cf Thanks in Advance Ladislav

[Dovecot] Convert plugin
by Egbert 03 Aug '10

03 Aug '10

Hi, I'm trying to convert users from a sendmail server to a postfix/dovecot server. All works fine but one of the last things is to rescue the messages in /var/mail/<user> on the old server. This seems very straitforward using the convert plugin but with the settings from the wiki, nothing happens when the user logs in. Do I need a private namespace for this as suggested elsewhere in the wiki? I experimented with mb2md.pl and that seems to do what we need but having the old mail converted upon login is much more attractive. In that way we hope that we can also find some 'dead' users. TIA Egbert Jan

[Dovecot] Plugin Handle input messages
by Alex Baule 03 Aug '10

03 Aug '10

Hi Timo.... I try to change my plugin to read the input email to increase a header line and one \r\n. But i need help to get this input.... My plugin is based in zlib plugin. In "static int zlib_permail_get_stream" function, have it. if (imail->data.stream != NULL || (_mail->uid == 0 && zuser->save_handler == NULL)) { return zmail->super.get_stream(_mail, hdr_size, body_size, stream_r); } I think this is the line that return the stream that is the stream sent by client. I try to change this line and put inside this IF , a call to my function to handle with the input email from client. But i got some errors about the input part. In other email, Timo said, to get the S and W flags in the email name, i need to intercept the email input from client to dovecot, in this part is done the W and S calculation. Timo, where is the part that i can get the input from client ?

[Dovecot] quota not updated

Hi, we're using quota with the maildir backend. When new mail arrives, the quota gets updated. But when mail is expunged, quota stays the same (see imap dialog below).

[Dovecot] Mbox corruption - Inbox beginning with 'FFrom' or 'FrFrom'
by Henri Khou 03 Aug '10

03 Aug '10

Hi, Since the 23rd of March, we encounter mailbox corruption for some users (15 out of 5000) using POP mainly via Thunderbird. Symptoms are : -users can login but fail to receive new mails and fail to read their inbox -Dovecot.log : ar 29 11:00:06 Error: POP3(user_login): Couldn't init INBOX: Mailbox isn't a valid mbox -The mailbox start with either 'FFrom or 'FrFrom' We can temporarily fix the issue by manually editing the mailbox so that it begins with a proper 'From'. For some users, the problem reoccurred after we apply this workaround. I have to mention that this server has been running fine since almost a year with the current hardware and software configuration. Does anybody has an idea regarding this issue?

[Dovecot] Dovecot 2.0.rc3 doesn't compile with custom OpenSSL
by Andreas M. Kirchwitz 03 Aug '10

03 Aug '10

Hi folks, when building Dovecot 2.0.rc3 (never used any other 2.0.X before, so this issue might not be new to that specific release), then compilation fails on anything that is linked against the new "libdovecot-login.so" library. For example, "imap-login" fails: /bin/sh ../../libtool --tag=CC --mode=link gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -Wstrict-aliasing=2 -I/usr/local/ssl/include -o imap-login client.o client-authenticate.o imap-login-settings.o imap-proxy.o ../../src/login-common/libdovecot-login.la ../../src/lib-dovecot/libdovecot.la -lrt libtool: link: gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -Wstrict-aliasing=2 -I/usr/local/ssl/include -o .libs/imap-login client.o client-authenticate.o imap-login-settings.o imap-proxy.o ../../src/login-common/.libs/libdovecot-login.so ../../src/lib-dovecot/.libs/libdovecot.so -lrt -Wl,-rpath -Wl,/usr/local/Dovecot-2.0.rc3/lib/dovecot /usr/bin/ld: warning: libcrypto.so.1.0.0, needed by ../../src/login-common/.libs/libdovecot-login.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libssl.so.1.0.0, needed by ../../src/login-common/.libs/libdovecot-login.so, not found (try using -rpath or -rpath-link) ../../src/login-common/.libs/libdovecot-login.so: undefined reference to `OBJ_txt2nid' [...] collect2: ld returned 1 exit status make[3]: *** [imap-login] Error 1 make[3]: Leaving directory `/usr/local/src/dovecot-2.0.rc3/src/imap-login' I'm not using system OpenSSL but a custom installation in /usr/local/ssl. According to the documentation, Dovecot is smart enough to get everything it needs from the /usr/local/ssl/lib/pkgconfig/*.pc files. Dovecot 1.2.X just compiles fine if configured like this: ./configure --prefix=/usr/local/${DOVECOTVER} --with-ssl=openssl The problem with Dovecot 2.0.rc3 is, that libdovecot-login.so isn't given the correct pathes for the OpenSSL libraries: $ ldd src/login-common/.libs/libdovecot-login.so linux-gate.so.1 => (0x00b6e000) libssl.so.1.0.0 => not found libcrypto.so.1.0.0 => not found libdl.so.2 => /lib/libdl.so.2 (0x00b2a000) librt.so.1 => /lib/librt.so.1 (0x004d4000) libc.so.6 => /lib/libc.so.6 (0x00110000) /lib/ld-linux.so.2 (0x006e7000) libpthread.so.0 => /lib/libpthread.so.0 (0x009c6000) So everything depending on libdovecot-login.so will fail. Setting "SSL_CFLAGS" and "SSL_LIBS" manually doesn't help because Dovecot already sets these perfectly fine via pkg-config: env SSL_CFLAGS="-I/usr/local/ssl/include" SSL_LIBS="-L/usr/local/ssl/lib -Wl,-R/usr/local/ssl/lib -lcrypto -lssl" ./configure --prefix=/usr/local/${DOVECOTVER} --with-ssl=openssl Only the hard way works: env CPPFLAGS="-I/usr/local/ssl/include" LDFLAGS="-L/usr/local/ssl/lib -Wl,-R/usr/local/ssl/lib -lcrypto -lssl" ./configure --prefix=/usr/local/${DOVECOTVER} --with-ssl=openssl However, setting CPPFLAGS and LDFLAGS shouldn't be necessary because SSL_CFLAGS and SSL_LIBS already contain the information that is needed to build a proper library. They are just not used when linking libdovecot-login.so ;-) Greetings, Andreas

[Dovecot] Date problem after import
by Andreas Schenk 03 Aug '10

03 Aug '10

Hi, am running into an import problem: After I upgraded an Mac OS X 10.5.8 Server to Mac OS X 10.6, not all, but quite some mails show wrong dates. They are dated to the year 2020, which is obviously not possible for mail that has been sent long ago. Now 10.5 to 10.6 is a move from cyrus to dovecot and the migration scripts used by Apple are supposed to do a nice migration. I have seen this suceed a lot of times, but this time not. As far as I understand, dovecot uses the modification date of the email to build its index and deleting the index should make it being rebuilt. But my "wrong" emails also have wrong modification dates. Only the headers inside the mail text still show the correct dates. My guess is, that something got wrong when migrating from cyrus. Even maybe the cyrus db might have been corrupt in the first place. As I can't go back and reimport I have to live with the situation. My plan to fix it is to write a script to traverse the mailbox hierarchy, delete the index files and have all email files with a modification date in 2020 be set to a modification date that is extracted from its contents "Date:" header. Now my question is, if you think this way is good, feasible or if another solution springs to the mind of those more adept with dovecot. Any help is appreciated.

[Dovecot] Dsync ignores INBOX when converting from mbox to maildir
by Jan Vítek 03 Aug '10

03 Aug '10

Hi, I am trying to convert email box in mbox format to maildir++. It converts all folders except INBOX. For example: dsync -D -v -f -u 'info(a)example.org' mirror 'maildir:~/Maildir' prints: dsync(info(a)example.org): Info: Sport: only in source So it converts Sport folder, but INBOX folder is ignored. dovecot.conf contains: mail_location = mbox:~/mail:INBOX=/var/mail/%u File /var/mail/info(a)example.org contains email messages. Dovecot is in version v2.0.rc3. Do you have any advice what am I doing wrong? -- Kind Regards Jan Vítek ČESKÝ WEBHOSTING s.r.o. Tel: +420 605 25 25 25 E-mail: info(a)cweb.cz http://www.cweb.cz

[Dovecot] Updating Database records from a Plugin
by John O'Brien 03 Aug '10

03 Aug '10

Guys, In the file /etc/dovecot-pgsql.conf I have driver = pgsql connect = host=localhost dbname=ivr.db user=ivr password=passwd default_pass_scheme = PLAIN password_query = SELECT password FROM embedded_device WHERE username='%u' user_query = SELECT home, uid, gid FROM embedded_device WHERE username='%u' In the table embedded_device there is a field called PIN. My plugin has the "user" and the "pin_value". What I want to do from the plugin is the following: UPDATE embedded_device SET PIN=pin_value WHERE username=user; Questions: Is there a way to locate the exiting database open connection? Is there a way to use the dovecot sql API to set the value of field? I have been looking for examples and have not been very successful. Regards, John

[Dovecot] [2.0] Experience in production environment
by Luigi Rosa 03 Aug '10

03 Aug '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I decided to put 2.0-pre3 in a couple of production environments with about 50 users each. The configuration is what I consider my own standard: Dovecot, Postfix with authentication via Dovecot, postfixadmin, maildir, userbase on MySQL. The new configuration schema is very flexible and much better than the "monolithic" file. The configuration conversion utility is very useful. No issue to report, the logfile is clean. The only difference between 2.0 and the previous version is the RIM server. Some users have configured their blackberry to synchronize the phone with their mailbox in IMAP. Previously RIM kept a connection open, after upgrading to 2.0, RIM opens a connection and then closes it. This is not an issue, because the synchronization is ok, and I think that is better this way than to keep an oper socket. Just for curiosity: it happens only to me and why this happens?

[Dovecot] Plugin for XFS project quota
by Wessel Dankers 02 Aug '10

02 Aug '10

Hi, I just finished writing a small plugin that reports XFS project quota in de IMAP component of Dovecot (1.2, currently). It was written to fill the needs of our organization but someone else might find this useful as well. In its current form it's not suitable for inclusion in the generic quota backend (see “Drawbacks”). Features: - every mailbox/folder can have its own project ID; - every project ID is mapped to a quota “root”; - caching to ensure reasonable performance; - Debian APT repository available; - LGPL 3 (just like Dovecot itself). Drawbacks: - quota are readonly, you'll have to manage limits and project assignment yourself; - IMAP only: I tried to write a generic quota backend, but the current setup of the quota plugin does not really seem to permit this; - extremely Linux-specific: assumes devices to be available under /dev/block/<maj>:<min> (this is valid for at least Debian lenny); - received only very limited testing; - no documentation whatsoever. How to get it: Sources: https://www.non-gnu.uvt.nl/pub/dovecot-prjquota/ Subversion: https://svn.non-gnu.uvt.nl/uvt-dev/trunk/sources/dovecot-prjquota/ Debian (amd64): deb http://non-gnu.uvt.nl/debian lenny dovecot-prjquota deb-src http://non-gnu.uvt.nl/debian lenny dovecot-prjquota Configuration: protocol imap { ... mail_plugins = imap_prjquota ... } Setting up XFS project quota in general: http://blogs.cae.tntech.edu/mwr/2009/09/01/setting-up-project-quotas-under-… cheers, -- Wessel Dankers <wsl(a)fruit.je> “Sysadmins busy fighting SPAM.”

[Dovecot] LDAP + mail_location: Get "%d" from customfield
by Denny Schierz 02 Aug '10

02 Aug '10

hi, my mail_location looks like: mail_location = maildir:/imap/spool/%d/%1n/%n:INDEX=/imap/spool/% d/indexes/%1n/%n for example: /imap/spool/domain.foo/a/anton/new The problem is, that the user log in with only the username and no domainpart. So, Dovecot looks into: /imap/spool/a/anton/new what isn't correct. We created an LDAP entry in which domain the user is and searching for a way, to get it working. So, only what I want is to use our customfield as domainpart for the mail_location. Postfix works perfect and delivers the messages in the correct folder. any idea? cu denny

[Dovecot] need convert-tool advice
by Dave McGuire 31 Jul '10

31 Jul '10

Hi folks, I've got a few thousand accounts that I'd like to convert from mbox to maildir. I'm looking at using convert-tool from the command line to do this, but I'm uncertain about the command line syntax, so I hope someone can take a moment to go over this with me. I'm running dovecot 1.1.6 on this system. Mail accounts are not tied to UNIX system accounts, I'm using the dovecot LDA, users do not have home directories, everything is controlled from a database, and mail directories take the form of: /var/spool/mail/<domainname>/<username>/... The mail directories contain mbox-style spool files, including "inbox" and any user-created mbox-format folders. The entire hierarchy is owned by vmail.vmail. I'd like to batch-convert these offline in such a way that it's transparent to users. Here's what I have so far: ------------------------------------------------------------ mv ${user} ${user}-mbox convert_tool ${user} \ /var/spool/mail/${domain}/${user} \ mbox:/var/spool/mail/${domain}/${user}-mbox:\ INBOX=/var/spool/mail/${domain}/${user}-mbox/inbox \ maildir:/var/spool/mail/${domain}/${user} ------------------------------------------------------------ (sorry about that incomprehensibly long command line, I tried to break it intelligently) ...then I'll change the "mail" field returned by the database query to include maildir instead of mbox. I'll wrap the whole thing in a script and do it in one run. Is this correct usage of convert_tool's command line options? The thing that confuses me is the "home directory" command line option, not sure what that's for, as my mail users don't have home directories...at least not in the UNIX sense, does it mean something else? Will the users notice anything different here, with respect to UIDs, indices, or anything like that? If this is completely the wrong way to do it, I'm not opposed to using a different tool like mb2md.pl, but I looked at that and couldn't quite figure out how to make it work within my current directory structure. Thanks, -Dave -- Dave McGuire Port Charlotte, FL

[Dovecot] performance problems with {s,m}dbox
by Jake Johnson 31 Jul '10

31 Jul '10

using rc3 and with the latest pigeonhole, I had problems with dovecot (deliver) keeping up with high volumes of E-mail. I tried sdbox, mdbox, and cyrdir all with similar (failed) result. using the default Maildir I had no problems. I did not try mbox. The problems seemed to happen when there were multiple deliver's running to the same folder I had defined in my sieve rules, either it would timeout and fail, or timeout and get delivered to my inbox, crash, or eventually halt because the queue would reach 20,000 messages which is the maximum with my postfix configuration. Everything was fine when I was using Maildir, no errors and no sieve errors/timeouts. perhaps it is more of an issue with pigeonhole than sieve, but thought I would post my experience using dbox, since it sounded like it was a winner based on performance.

[Dovecot] Dovecot and SSD
by Bryan Vyhmeister 30 Jul '10

30 Jul '10

I'm considering setting up my own mailserver with Dovecot 2.0 (as soon as it's out) and SSD. I'm debating whether it's worth it or not. I have been running a mailserver with the Dovecot 1.1 train for a couple of years and it's been flawless and amazing. I'm thinking about using either FreeBSD 8.1 w/ZFS or OpenBSD 4.8-beta on a 64 GB or 80 GB SSD (Corsair or Intel) using Dovecot 2.0 and mdbox. It seems like mdbox would benefit the most from an SSD because reads would be extremely fast while minimal writes (comparatively) take place due to the way mdbox is structured. I guess what I'm saying is that even if the SSD has average to slow write speeds the fast read speeds would make a big difference in many operations. Any thoughts? Alternately, run either option on a hard drive with indexes on fast flash memory. Anyone tried something like that? Thank you. Bryan

[Dovecot] relay access denied problem thru iphone imap auth
by Allen Walker 30 Jul '10

30 Jul '10

I'm using postfix smtpd / dovecot. Running imaps, imap, pop3s, pop3. I have a ssl certificate setup. Everything works fine via IMAP except sending to an email from outside the network to a recipient outside the network. The problem is when someone (and this is being tested thru the iphone email client configured to use imap) logs in, they can read messages but cannot send to an address outside my network, assuming they are logged in outside the network. If you they are logged in inside the network, they can send to anyone just fine. The Log: Jul 29 20:09:41 ubuntu dovecot: imap-login: Login: user=<amit>, method=PLAIN, rip=166.205.142.84, l ip=192.168.1.68, TLS Jul 29 20:10:02 ubuntu postfix/smtpd[28892]: warning: 166.205.142.84: hostname 166-205-142-084.mobi le.mymmode.com verification failed: No address associated with hostname Jul 29 20:10:02 ubuntu postfix/smtpd[28892]: connect from unknown[166.205.142.84] Jul 29 20:10:06 ubuntu postfix/smtpd[28892]: NOQUEUE: reject: RCPT from unknown[166.205.142.84]: 55 4 5.7.1 <xxx(a)gmail.com>: Relay access denied; from=<amit(a)outsidedomain.com> to=<xxx(a)gmail.c om> proto=ESMTP helo=<[10.67.168.110]> Jul 29 20:10:06 ubuntu postfix/smtpd[28892]: disconnect from unknown[166.205.142.84] */etc/postfix/main.cf:* smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) biff = no # appending .domain is the MUA's job. append_dot_mydomain = no # Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h readme_directory = no # TLS parameters smtpd_tls_cert_file = /etc/ssl/certs/server.crt smtpd_tls_key_file = /etc/ssl/private/server.key smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache # See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for # information on enabling SSL in the smtp client. myhostname = mydomain.com alias_maps = hash:/etc/aliases, hash:/var/lib/mailman/data/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = mydomain.com, localhost mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 mailbox_command = procmail -a "$EXTENSION" mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all relay_domains = lists.mydomain.com # I use this as I have mailman also running transport_maps = hash:/etc/postfix/transport mailman_destination_recipient_limit = 1 relayhost = inet_protocols = ipv4 smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth-client smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination

[Dovecot] Dovecot LDA
by Daminto Lie 30 Jul '10

30 Jul '10

Hi, I was wondering if I could get some help with Dovecot. I have just recently set up a mail server that runs on Ubuntu Server 10.04. It has got the current version of postfix and Dovecot. I have also got the squirrelmail set up as my webmail. Everything is fine. However, I have been reading some emails posted by Dovecot users regarding Dovecot LDA. I wonder if anyone might be able to let me know the benefits it might offer so that i could make a decision as to whether I need it or not. Thank you very much in advance

[Dovecot] Looking for a Plug-In developer
by John O'Brien 28 Jul '10

28 Jul '10

Hi, We need a small plug-in developed for dovecot. We are looking to pay for for its development. We need to add support for a custom IMAP command. The command is for the storage of a numeric PIN field in a database. The database is PostgreSQL. Another table in the database defines the minimum and maximum length of the numeric PIN field. The IMAP client server exchange after a user login resembles the following. C: A0001 CHANGE PIN 243289 S: A0001 OK CHANGE successful The numeric PIN number is stored in a field within a table the login username as key. Example errors are: C: A0001 CHANGE PINFJ 24DDD89 S: A0001 NO invalid password type C: A0001 CHANGE PIN 24DDD89 S: A0001 NO invalid characters C: A0001 CHANGE PIN 23 S: A0001 NO password too short C: A0001 CHANGE PIN 234567890123 S: A0001 NO password too long C: A0001 CHANGE PIN 0000 S: A0001 NO password blacklisted We believe this is not a big task for someone familiar with the design and implementation of dovecot plug-ins. We want to minimise our leaning and just get a result. If you are interested in undertaking this development please contact me with a simple proposal. We will require the source code and copyright assignment.

Hi, Has anyone got the chance to get this running? I'm permanently getting this Serverbug error ... ;( *"[SERVERBUG] failed to send email"* ... This happens when I try to drag&drop mails from one to the other folder within a IMAP-session. What version of Dovecot must I have to get this plugin working? Or will it generally be broken in upcoming new releases of Dovecot? Best Regards Leander S.

[Dovecot] dovecot lda & sieve: resubmit folder for resieving
by Axel Thimm 28 Jul '10

28 Jul '10

Hi, I'm currently restructuring my mail archives and migrated from a decade and a half old procmail supported solution to sieve. While doing so I often found that I'd like to filter a bunch of messages (with "bunch" in the area of 1-10K) with my shiny new sieve script. I found in the wiki a way to do that: http://wiki.dovecot.org/HowTo/RefilterMail And it works well, it picks the mails via IMAP and resubmits them to dovecot-lda. But unfortunately the IMAP flags including \Sent, \Flagged etc are lost in the process. I started checking for other solutions beside getmail that might extract the imap flags as well, but I wouldn't know how to pass them to dovecot-lda. Would it make sense to suggest to have dovecot offer this kind of reprocessing itself? That way nothing would get lost in any transition. -- http://ATrpms.net/

Hi again, I`m a bit confused how to store a SSHA256 password in the database and I can`t find any information in the wiki. Do I have to store the SHA256 hash and the salt separately (what would the password_query be like in this way) or just the final SSHA256 hash? Regards Patrick

[Dovecot] Cyrus Virtual Domains: Domain migration from Cyrus
by Denny Schierz 27 Jul '10

27 Jul '10

hi, we want to migrate from Cyrus 2.x to Dovecot 1.x (!). We use the virtual domain feature from Cyrus for a better disk partitioning: /var/imap/domain.a/user/foo .. /var/imap/domain.b/user/foo .. /var/imap/domain.c/user/foo .. In a exported skiplist DB, it shows like: ================= domain.a!user.foobar 0 int foobar(a)domain.a lrswipcda postmaster(a)domain.a domain.a!user.han 0 int han(a)domain.a lrswipcda domain.b!user.solo 0 int solo(a)domain.b lrswipcda domain.b!user.yoda 0 int yoda(a)domain.b lrswipcda domain.c!user.luke 0 int luke(a)domain.c lrswipcda postmaster(a)domain.c That allows us, to separate the domains from each other on the filesystem. The cyrus imapd.conf config: defaultpartition: domaina partition-domaina /var/spool/imap/domaina partition-domainb /var/spool/imap/domainb partition-domainc /var/spool/imap/domainc What is the best way, to use this layout under Dovecot? cu denny ps. Cyrus gets this mails via LMTP over TCP from sendmail and Dovecot 1.x dont' have this service and I use postfix for smtp-> smtp-local-lmtp-> Dovecot. -- Denny Schierz <linuxmail(a)4lin.net>

[Dovecot] using Lazy_Expunge to enforce retention policy
by Jim Salter 26 Jul '10

26 Jul '10

Hi, I've been experimenting with using Lazy_Expunge as a tool to enforce document retention policies (by keeping users from deleting emails forever, instead expiring them after a set time). My problem is, how do I keep the user from deleting/expunging mails *inside the expunge folder itself*? I am using dovecot-1.2.10 built from FreeBSD's ports tree, and I am using the following settings for the "expunged" folder of Lazy_Expunge, as part of the "three namespaces" approach suggested in the wiki: # namespaces for lazy_expunge plugin: namespace private { prefix = .EXPUNGED/ separator = / location = maildir:/usr/local/vpopmail/domains/%d/%n/EXPUNGED } When a user expunges mail, it shows up in the folder listed just fine. But if the user expunges mail from /that/ folder, it's gone forever, which defeats the purpose in regard to "enforcing retention." As a partial workaround, I tried adding hidden=yes and list=no to the setting, and restarting dovecot: # namespaces for lazy_expunge plugin: namespace private { prefix = .EXPUNGED/ separator = / location = maildir:/usr/local/vpopmail/domains/%d/%n/EXPUNGED hidden = yes list = no } The problem is, while this does indeed *hide* the namespace from the user, it doesn't prevent them from *using* it if they know about it - I discovered this because Thunderbird still "remembered" the namespace from before I hid it; experimenting confirmed that, yes, I could still use Thunderbird to go into my expunged folder and permanently delete any email in it. If I remove the account from Thunderbird *completely* and reset it up from scratch, I can no longer "see" the namespace - but that's weak security at best, as I can still manually navigate to it and wreak havoc. How can I use Lazy_Expunge to completely PREVENT users from deleting email permanently? Thank you!

[Dovecot] Dovecot 2 and expire
by Brandon Lamb 26 Jul '10

26 Jul '10

expire_dict = proxy::expire I found this expire_dict somewhere, might have been the 1.x wiki, but on the expire plugin page there is no mention of it. I am trying to troubleshoot why my mysql table has no entries. Do I need this line? Is that correct for using mysql? In dict {} I have expire = mysql:/etc/dovecot/conf.d/dovecot-dict-expire.conf.ext and in plugin {} i have expire_dict = proxy::expire expire = Trash 30d expire2 = Trash/* 30d expire3 = Spam 14d expire4 = Spam/Removed 6h expire5 = Spam/Delivered 2d expire6 = Deleted* 30d expire7 = Archive 30d Contents of dovecot-dict-expire.conf.ext connect = host=servername dbname=mail user=un password=pw map { pattern = shared/expire/$user/$mailbox table = expires value_field = ts_expires fields { username = $user mailbox = $mailbox } } I must admit I dont understand what pattern means, I just copied from something when I was setting this up.

[Dovecot] Dovecot and LDAP - virtual hosting problem
by Pavel Dimow 26 Jul '10

26 Jul '10

Hello, I have a small ISP and we have a dovecot for virtual mail hosting with a postfix and openldap as backend. Now the problem is that there is one primary domain (example.com) and many other virtual domains with different users. When user from primary domain logs in, he is using username as his username (without domain part) and when user from virtual domain logs in, he uses username@virtualdomain as his username. I don't know how to make dovecot-ldap.conf to authenticate both users from the same ldap tree. My ldap tree is organized like: ou=people,o=example.com,dc=acme ou=people,o=somevirtdomain.cp,dc=acme and so on... The only one thing that comes on my mind is something like (default domain) in dovecot.conf (if %d is empty then %d=examle.com, othewise...) I know this option does not exist but is just comes on my mind... Maybe some specific filter_search or something like that? Than you for any help in advance.

[Dovecot] Problem with hard links in lda - please help
by Fabio Ferrari 26 Jul '10

26 Jul '10

Hello, I'm trying to enable hardlinks for messages sent to mutiple users. (I need this because I have mailing lists with 5000 users used many times a day). I've read that, to do this, I have to write a script that uses the /usr/local/libexec/dovecot/deliver command in this way: deliver -p <FILE> -d <USER1> -d <USER2> Of course, I enabled the "socket listen" option in the configuration file to get the command line work, and set the maildir_copy_with_hardlinks = yes The deliver command works, so I have the messages correctly in the "new" directory in the maildir folder. But if I list the files, they have the "links" number = 1, so I see that the file was copied, not hardlinked! I see in the page http://wiki.dovecot.org/LDA that is possible, in fact it says Parameters [...] -p <path>: Path to the mail to be delivered instead of reading from stdin. If using maildir the file is hard linked to the destination if possible. This allows a single mail to be delivered to multiple users using hard links, but currently it also prevents deliver from updating cache file so it shouldn't be used unless really necessary. (v1.1+) Of course, I use a version 1.1+ (1.2.12). Please help, thanks in advance Fabio Ferrari

[Dovecot] antispam plugin troubleshooting
by Bradley Giesbrecht 26 Jul '10

26 Jul '10

I built the dovecot antispam plugin and renamed it so I could have multiple backends installed at the same time. http://johannes.sipsolutions.net/Projects/dovecot-antispam I tried recompiling antispam without renaming the .so and I get the same result indicated below. All other plugins and the system as a whole has been functioning normally. Only when I add antispam plugin does dovecot not start and perform as expected. What can I do to find the reason dovecot is not loading lib90_antispam_mailtrain_plugin.so successfully? Below is some info I could think to supply for help.
