[Dovecot] address extension going into folder
by Phil Howard 01 Jul '10

01 Jul '10

Is it possible with a simple config change to make address extensions, e.g. alice+sales(a)example.com, go into a folder, e.g. .INBOX.sales, and do so ONLY if that folder already exists (and just go into INBOX if it does not exist)?

[Dovecot] Can't establish Dovecot authorization in Exim.
by 秋元亮二 30 Jun '10

30 Jun '10

Hi, I have some problem in Dovecot authorization in Exim for outgoing SMTP. Version of Exim is 4.69 and the Exim was compiled with "AUTH_DOVECOT=yes" and "AUTH_PLAINTEXT=yes". Version of Dovecot is 1.2.12. I use SSL for IMAP. Is Exim neccesary to use SSL(TLS) for authorization of outgoing SMTP? Configuration files is as follows; - Exim ---------------------------------------------------------- dovecot_login: driver = dovecot public_name = LOGIN server_socket = /var/run/dovecot/auth-client server_set_id = $auth1 dovecot_plain: driver = dovecot public_name = PLAIN server_socket = /var/run/dovecot/auth-client server_set_id = $auth2 ---------------------------------------------------------- - Dovecot ---------------------------------------------------------- auth default { mechanisms = plain login passdb pam { args = cache_key=%u dovecot } userdb passwd { } socket listen { #master { #} client { path = /var/run/dovecot/auth-client mode = 0666 } } } ---------------------------------------------------------- Do I have to set other than that, like TLS for Exim? Thanks in advance. _________________________________________________________________ Hotmailがサクサク動く！フィッシング詐欺も怖くない http://o.jp.msn.com/ie8/

[Dovecot] "forgot my password" feature
by Mustafa Cagatayli 30 Jun '10

30 Jun '10

Hi, We have a mail server with the postfix/Squirrelmail/Dovecot(v.1.1.11) combination which we have user data on MySQL through virtual users. We have configured the SquirrelMail interface so that users can now change their own passwords. Is there any opensource solution to provide "self service password management" which would allow us to add the "I forgot my password. Lets reset it" feature which would do the authentication with the help of some random personal data or personal question/answer combination ? Regards. -- Mustafa Çağataylı BİM

[Dovecot] Use both SQL and LDAP
by Shayne Jellesma 29 Jun '10

29 Jun '10

Hey guys, I am just wondering if it is possible to use both SQL and LDAP queries at the same time to get information. Example on why I want to do this: I work at a school where we have the need for 2 separate types of mailbox configuration (better wording is eluding me at the moment). Staff and Students currently share the same email server. I would like to be able to give staff a bigger inbox (eg: 500MB) than students (eg: 50MB). The way I am thinking, if this is even possible, to pull username and group membership from Active Directory. Check the groups against a SQL query to give the user the appropriate mailbox size. Also, having email is a privilege, not a right at my school so is it also possible to check if a user is part of a BannedEmailUsers or AllowedEmailUser group so I could quickly and effectively disable accounts as needed. I apologise if this is a little hard to follow. Writing what I want has never been a strongpoint for me J I also apologise if this has been asked, or information is available somewhere. I did search and didn't come up with much. Regards, Shayne Jellesma Network Administrator / ICT Support St Martins Lutheran College

[Dovecot] %d/%n doesn't work... why?
by William Ottley 29 Jun '10

29 Jun '10

Hello all, I've been trying to setup my postfix and dovecot to AUTH with mysql, and I'm almost there! BUT, for some reason, dovecot won't create the folders in their proper location. For some reason, instead of going into /var/vmail/pplsnet.com/{username}location, where the postfix put all the emails, dovecot creates a whole new set of folders in /var/vmail/{username} I have attempted to force dovecot to put into a sub directly, without using the %d, but that doesn't work either: #mail_location = mbox:/var/vmail/%d/%n mail_location = mbox:/var/vmail/pplsnet.com/%n Where do I look to figure out why its not putting it into the %d/%n location? does it have to do with the fact that AUTH graps the username, and NOT the domain name? (via mysql)? I have included dovecot -n and postconf -n.. can anyone take a quick guess and figure out what I should be doing? thanks! *dovecot -n* # 1.0.7: /etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot log_timestamp: %Y-%m-%d %H:%M:%S protocols: pop3 pop3s login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/pop3-login first_valid_uid: 150 last_valid_uid: 150 mail_extra_groups: mail mail_access_groups: mail mail_location: mbox:/var/vmail/pplsnet.com/%n maildir_copy_with_hardlinks: yes mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/pop3 auth default: mechanisms: plain login digest-md5 cram-md5 passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: mail master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: mail *postconf -n: *alias_database = hash:/etc/postfix/aliases alias_maps = hash:/etc/aliases append_dot_mydomain = no biff = no broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix debug_peer_level = 2 disable_vrfy_command = no html_directory = no inet_interfaces = all mail_owner = postfix mail_spool_directory = /var/spool/mail mailbox_size_limit = 500000 mailq_path = /usr/bin/mailq manpage_directory = /usr/share/man message_size_limit = 10000 mydomain = rnd myhostname = mail.pplsnet.com mynetworks = 174.xx.xx.0/24 myorigin = $myhostname newaliases_path = /usr/bin/newaliases queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.2.10/README_FILES recipient_delimiter = + relayhost = sample_directory = /usr/share/doc/postfix-2.2.10/samples sendmail_path = /usr/sbin/sendmail setgid_group = postdrop smtp_tls_note_starttls_offer = yes smtp_use_tls = yes smtpd_banner = $myhostname smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = smtpd_sasl_path = private/auth smtpd_sasl_security_options = noanonymous smtpd_sasl_type = dovecot smtpd_tls_CAfile = /etc/postfix/gd_bundle.crt smtpd_tls_cert_file = /etc/postfix/pplsnet.com.crt smtpd_tls_key_file = /etc/postfix/www.pplsnet.com.key smtpd_tls_loglevel = 1 smtpd_tls_received_header = no smtpd_tls_session_cache_timeout = 3600s smtpd_use_tls = yes tls_random_source = dev:/dev/urandom unknown_local_recipient_reject_code = 450 virtual_alias_maps = mysql:$config_directory/mysql_virtual_alias_maps.cf virtual_gid_maps = static:12 virtual_mailbox_base = /var/vmail virtual_mailbox_domains = mysql:$config_directory/ mysql_virtual_domains_maps.cf virtual_mailbox_maps = mysql:$config_directory/mysql_virtual_mailbox_maps.cf virtual_minimum_uid = 150 virtual_uid_maps = static:150 * *

[Dovecot] Dovecot-2.0 conf misc questions
by Thomas Hummel 29 Jun '10

29 Jun '10

Hello, I'm setting up a dovecot-2.0.beta6 install and I'm experiencing the following issues/questions : 1. Converting the config file # /usr/local/dovecot-2/bin/doveconf -n -c /usr/local/dovecot-1.2.12/etc/dovecot.conf : [...] doveconf: Fatal: Error in configuration file /usr/local/dovecot-1.2.12/etc/dovecot.conf line 176: Unknown setting: process_limit but # grep -i process_limit /usr/local/dovecot-1.2.12/etc/dovecot.conf # Well, it doesn't bother me much since I made the dovecot-2 conf from scratch anyway. 2. Changing the process limit In 10-master.conf, I changed 'service imap''s 'process_limit' from 1024 to 4096 which caused : Warning: service auth { client_limit=4096 } is lower than required under max. load (5320) Where does the 5320 come from ? 3. The = <file syntax Is there anything to know about this new syntax other than files are introduced by "<" ? 4. The "filter" hierarchy My understanding is that protocol, remote, local must be specified in the following order protocol name { remote <ip|name> { local <ip|name> { and that for a match in several blocks, the more specific wins. but it's not clear to me where they are valid and if we can negate (with a ! for instance) an argument. For instance, I want to implement the typical case of "let clients from the inside network perform a plain auth over a clear connection, require SSL before auth for the outside network clients". For that, I want to put remote <internal network address> { disable_plaintext_auth = no } in 10-auth.conf and let the 'disable_plaintext_auth = yes' in dovecot.conf But : . why is this default not in 10-auth.conf file ? . would I have been allowed to do, for instance, in that file at the same line protocol imap { remote <internal network address> { disable_plaintext_auth = no } ? . would I have been allowed to do, for instance, in that file at the same line protocol ! imap ... or remote ! <some address> ? Besides, if I set ssl=required, do I still need disable_plaintext_auth = yes ? 4. auth unix listner Default is the unix socket 'auth-userdb'. Which processes communicate through this one ? Does that mean the the auth process is not the process which performs the actual passdb/userdb lookup ? In that case what is the 'userdb process' ? Same question : what is the auth-client socket used for ? Finally, would it make sense to declare other auth listeners than the two listed by default in the 10-master.conf file ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Dovecot dies, maybe ntpdate related. I'm new to dovecot
by Xavi Montero 28 Jun '10

28 Jun '10

Hi all, my first post. After years with an old server, a couple of months ago I've installed a new one. We use IMAP. After research, I chosed dovecot. It has been running for several weeks but from one week ago or so, it suddently dies about once per day. The only change done in the server one week ago has been to install ntpdate, running once per day in cron-daily. In the cron reports, ntpdate reports a time-jump of 9 seconds each night. We did this because "apparently" we did not a "soft time drift" installing the full ntp daemon, but I start thinking the time-jump crashes dovecot. QUESTIONS: - Might this time-jump cause dovecot to die? - I don't know wehere the dovecot logs are written to. Where do I start searching? Thanks to all!

[Dovecot] "forgot my password" feature
by Mustafa Cagatayli 28 Jun '10

28 Jun '10

Hi, We have a mail server with the postfix/Squirrelmail/Dovecot(v.1.1.11) combination which we have user data on MySQL as virtual users. We have configured the SquirrelMail interface so that users can now change their own passwords. Is there any opensource solution to provide "self service password management" which would allow us to add the "I forgot my password. Lets reset it" feature which would do the authentication with the help of some random personal data or personal question/answer combination ? Regards. -- Mustafa Çağataylı BİM

Others on this list would be more help than me regarding this. From the looks of it though (after browsing the dovecot.conf file, which is well documented btw) I don't think you'd need to change a thing. We'll certainly find out if that's the case or not.

[Dovecot] Pigeonhole Managesieve issue with Dovecot 2.0
by Tim Traver 26 Jun '10

26 Jun '10

Hi all, ok, I am running version v2.0.beta6 and the latest pigeonhole build to run managesieve and the sieve delivery filters... I am getting the following response from the managesieve port when connecting : Escape character is '^]'. "IMPLEMENTATION" "Dovecot" "SIEVE" "" "SASL" "PLAIN" "STARTTLS" "VERSION" "1.0" OK "Dovecot ready." But, I think that the SIEVE line is suppose to have all of the supported sieve functions like so : "SIEVE" "comparator-i;ascii-numeric fileinto reject vacation imapflags notify include envelope body relational regex subaddress copy" I modified the dovecot sieve config file to try and add (although they should all be added by default), and it still comes up blank... Am I missing something? what might cause it to not broadcast the sieve implementations that it has? Thanks, Tim.

[Dovecot] auth_cache_size
by Daniel L. Miller 25 Jun '10

25 Jun '10

I was going to ask how much space I should allocate for auth_cache_size - but decided to read the wiki first. Now I'll be more specific - Wiki says about 50 bytes per passdb, and up to 200 bytes for userdb - so my arithmetic says each combined entry needs 250 bytes budgeted. Assuming that's correct, I need some clarification. Let's start small. Assume ten users, all connected - and everybody also likes looking at everybody else's mailbox. So there are ten clients, each with at least ten connections (I say at least because each folder viewed within an account is its own connection, right?). How is the auth_cache used? If I have ten user/pass combinations - is that all that is stored? Or are there connection-specific entries as well? In other words, for the above example, do I have 10 x 250 bytes yields auth_cache_size=3, or do I need 10 x 10 x 250 yields auth_cache_size=30 - or am I totally off? -- Daniel

[Dovecot] Regenerate Index and Control Files
by John S 24 Jun '10

24 Jun '10

In a bad attempt of correcting a non-related error, I deleted, and recreated, the control and index directories; now, the only e-mail showing up, in all user mailboxes, is mail that has been delivered afterward. How do I make dovecot regenerate the control and index files so that the old e-mail shows up? John

Hello, I'm new here, and I'm from Germany, so please be patient with me because my English is not so good ;) I am searching for a Step-to-Step Guide to first-configure Dovecot. I want to create virtual Users wich can logon to my Server to a Webinterface to call theire mails. I think IMAP is the right protokoll but it should be safe, so i think IMAPs is better.

[Dovecot] quota_set leak

The quota plugin in 2.0.beta6 leaks 2KB "quota settings" pools. Here is a patch to plug this leak, assuming you intended the caller of quota_init to retain ownership of the quota_set. If on the other hand you intended for quota_init to assume ownership of the quota_set, then the quota_settings_deinit call belongs in quota_deinit. --- a/src/plugins/quota/quota-storage.c (beta6) +++ b/src/plugins/quota/quota-storage.c (patched) @@ -427,6 +427,7 @@ { struct quota_user *quser = QUOTA_USER_CONTEXT(user); + quota_settings_deinit(&quser->quota->set); quota_deinit(&quser->quota); quser->module_ctx.super.deinit(user); }

[Dovecot] Proxy Access (Manager/Secretary) Best Practices?
by Chris Hobbs 23 Jun '10

23 Jun '10

I've mostly got our dovecot+postfix+SOGo+openldap open source groupware replacement working the way I want it to; we're replacing GroupWise in our organization and I'm thrilled to be doing it. I'm supporting about 1,000 active staff users (and another 6,000 student accounts). I've got e-mail and calendar sharing working, and it does what it says it will do, but it is (go figure) different in concept from Proxy access under GroupWise. In GroupWise, I can give my secretary proxy access to my account and she can read all of my folders, see my calendars, and send e-mail as me. To someone that receives an e-mail or appointment request from her while she's proxied to me, there's no distinction at all. Is there a way to mimic this sort of functionality with the tools I've chosen? I've figured out that I can add additional 'mail' attributes to the secretary's record, and those addresses are available as drop-down choices in the SOGo web interface, but with the secretary's name and not the manager. Any advice will be much appreciated. And many thanks to the developers involved for writing and making available such amazingly good software. Eliminating the license fees we've been paying to Novell is allowing me to save a technician that surely would have been eliminated in budget cuts this year.

[Dovecot] More Dovecot 2.0 permissions issues
by Tim Traver 22 Jun '10

22 Jun '10

Hi Timo, ok, using the latest 2.0beta6... I can't figure out the settings for the log file to have the correct permissions. When the log file is created, it is created owned by root and 0600 permissions, which doesn't allow the lda to write to it if I use different users and groups for that main config... If I then chmod the log file to 666, then everything is happy, but again, if that log file is removed and created by dovecot, it will create it back with 0600 and the lda will error and not deliver mail because of it... I was not able to find anywhere else to set the mode of the log files or the mask that is used... here is the current config : # 2.0.beta6: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.0-RELEASE-p3 i386 auth_username_format = %Lu auth_username_translation = %@ auth_verbose = yes disable_plaintext_auth = no dotlock_use_excl = yes first_valid_uid = 100 listen = * lock_method = dotlock log_path = /local/logs/dovecot.errors mail_gid = 100 mail_location = maildir:%h/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_uid = 100 mmap_disable = yes passdb { args = /bin/checkpassword_dovecot_auth driver = checkpassword } plugin { quota = maildir sieve = ~/.dovecot.sieve sieve_dir = ~/Maildir/sieve } protocols = imap pop3 managesieve quota_full_tempfail = yes service auth { unix_listener auth-userdb { mode = 0660 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = prefetch } userdb { args = /bin/checkpassword_dovecot_deliver driver = checkpassword } verbose_proctitle = yes protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { mail_plugins = quota sieve } protocol imap { mail_plugins = quota imap_quota } Thanks, Tim.

[Dovecot] Postfix, MySQL, Dovecot LDA and alias domains
by Darek M 22 Jun '10

22 Jun '10

Hi there, I have a postfix/postfixadmin/mysql/dovecot install that was using 'virtual' for the LDA. I tried the 'dovecot' LDA to enable Sieve but ran into trouble with aliases. With domain "some-domain.com" being an alias to "somedomain.com", mail sent to *(a)somedomain.com would be delivered to the Maildir fine, but the 'dovecot' LDA tossed "unknown user" for anything sent to *(a)some-domain.com (the alias to the other domain). My dovecot.sql: driver = mysql connect = host=/var/lib/mysql/mysql.sock dbname=postfix user=dovecot password=dovecot user_query = SELECT concat('/home/vmail/', maildir) as home, concat('maildir:/home/vmail/', maildir) as mail, 5000 AS uid, 5000 AS gid, concat('maildir:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = '1' password_query = SELECT username as user, password, concat('/home/vmail/', maildir) as userdb_home, concat('maildir:/home/vmail/', maildir) as userdb_mail, 5000 as userdb_uid, 5000 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' The problem is fairly simple: Dovecot isn't being told anything about the 'alias_domain' table that pairs alias domains with actual ones. So the question is: do I add a second "user_query" in dovecot.sql, or is there an "alias_query" directive, or similar? And does anyone have a query that would point an alias domain to the real maildir? - Darek

[Dovecot] Outlook problem
by Patric Falinder 22 Jun '10

22 Jun '10

Hi, I have some problems that every time I start Outlook and retrieve my e-mails and then later tries to do it on my iPhone for example, I get some sort of problem that I can't get the mails. I searched around on the wiki and found the "outlook-no-nuls" and "outlook-idle" options, but where am I suppose to add them? I only have "pop3_uidl_format = %08Xu%08Xv" in my "protocol pop3 {}" and it didn't work to add it to a new line there. Thanks, Patric

[Dovecot] New mailbox & autocreate
by Bambero 21 Jun '10

21 Jun '10

Hi, First of all BIG THANKS for great piece of software. I have a small problem with autocreate. My mails are stored in: /var/mail Ex. /var/mail/test(a)test.pl/Maildir Account information comes from DB. So when new account appears in DB full path including home dir is created. But there is one small problem: Group always is "wheel". Autocreating ignores gid from DB and uses the group of the parent directory - in this case /var/mail. But when I create home dir manualy (setting right group) group of autocreated Maildir is OK. Is it possible to configure dovecot to set group from DB. Regards, Bambero

[Dovecot] Error: dict: Leaked a t_pop() call

21 Jun '10

I'm running dovecot 1.0.7 on CentOS 5.5, and I've configured it to work with PostfixAdmin (http://sourceforge.net/projects/postfixadmin/) Everything seems to work great, except for one problem. Any time a user logs in, I get errors like the following Jun 19 02:21:59 ve dovecot: dict: Leaked a t_pop() call in I/O handler (nil) Jun 19 02:21:59 ve dovecot: dict: Raw backtrace: dict [0x40e85e] -> dict [0x40e5cc] -> dict(io_loop_handler_run+0x1c9) [0x411279] -> dict(io_loop_run+0x18) [0x4106b8] -> dict(main+0x139) [0x408509] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x2ab19ec13994] -> dict[0x407589] The only information I could find online was from this mailing list a few years back: http://copilotco.com/mail-archives/dovecot.2007/msg08975.html The response seems to be "nobody keeps their quota in MySQL", but the setup I'm using is what's recommended by the authors of PostfixAdmin: http://postfixadmin.svn.sourceforge.net/viewvc/postfixadmin/trunk/DOCUMENTS… So, I guess my questions are these: 1) Is this error at all serious? Will it impact performance, or can it be safely ignored? 2) If it is something that should be addressed, do you think I would be better off trying to patch and recompile the 1.0.7 version, or just upgrading to a newer version of Dovecot (keeping in mind that 1.0.7 seems to be the latest available in CentOS repositories) Thank you for your time, and your outstanding software. -Brendan

Thanks for the information. I'm not trying to waste your time, and I wasn't really asking for 'help' per se, as much as simply a clear answer about whether that error was even worth worrying about. I'm well aware that 1.0.7 is a pretty old release, and you don't have much control over what the distro maintainers choose to package. Generally speaking, I think there are advantages (not introducing incompatibility with other software, simple dependency resolution, automatic security updates, etc.) to sticking with repo versions, unless you have a compelling reason to do otherwise. In this case, the bugfixes and improvements in quota accuracy are a good reason to upgrade. > > Please download 1.2.12, the current stable release, however read the > release notes because some settings will be incompatible with 1.0.x. > there wont be too many differences but might be some, depending on your > setup. I have moved to 1.2.12 and updated my dovecot-dict-quota.conf file, and it seems to be working great. Thanks again.

[Dovecot] Coredump while searching a folder
by Matthias Rieber 21 Jun '10

21 Jun '10

Hi, while searching through the message bodies in a real folder I got a coredump. I used the master user for this operation. dovecot.index* files have been removed before I started this operation. This looks a bit different to my previous report. Coredump: Program terminated with signal 6, Aborted.

[Dovecot] confused with %d/%n not working....
by William Ottley 20 Jun '10

20 Jun '10

Hi all, I'm trying to link in my "online" community of users, via mysql, with my mailserver. I have dovecot 1.0.7. I am using mysql to authenticate, and I'm trying to figure out what I should be doing to my sql query that checks the username which has a username field and a database field. everything works, as long as the username is "u%@d%" in the field, but to work with my other web application, the username is in one field, and the database is in another. can anyone make a suggestion as to how i can do the user_query to work this way? (both with dovecot and the postfix) any help would be greatly appreciated! dovecot: connect = host=localhost dbname=pplsnet user=xxxx password=xxxxxxx password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT '/var/vmail/%d/%n' as home, 'maildir:/var/vmail/%d/%n' as mail, 150 AS uid, 12 AS gid, concat('dirsize:storage=',quota) AS quota FROM mailbox WHERE username ='%u' AND active ='1' postfix: user = mail password = xxxx hosts = localhost dbname = mail table = mailbox select_field = CONCAT(domain,'/',maildir) where_field = username additional_conditions = and active = '1'

Big thanks for improvements in svn-trank Roundcube version, I am waiting for official release for update. Timo-san, which client most Dovecot compatible you think (non-Web)??

[Dovecot] coredump while accessing virtual folder with dovecot 2.0

Hi, I get a core dump with 2.0.beta6 (573cb66e9180) when I access virtual folders with the master user. Since ACLs are active I have to set a global ACL in .DEFAULTS to access all folders.

[Dovecot] Sieve isn't working
by Steven Weiß 20 Jun '10

20 Jun '10

Hi, I tried to get Sieve plugin running but I don't get it to work and actually have no idea what's wrong. My dovecot version is 1.2.12 and dovecot -n prints this: # 1.2.12: /usr/local/etc/dovecot.conf # OS: Linux 2.6.18-028stab064.7 i686 openSUSE 11.1 (i586) reiserfs log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot.log disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login first_valid_uid: 110 last_valid_uid: 110 mail_location: maildir:/var/qmail/mailnames/%d/%n/Maildir fsync_disable: yes lda: postmaster_address: postmaster(a)code-factory.de mail_plugins: sieve mail_plugin_dir: /usr/local/lib/dovecot/lda fsync_disable: no auth default: passdb: driver: passwd-file args: /usr/local/etc/passwd.dovecot userdb: driver: passwd userdb: driver: static args: uid=popuser gid=popuser plugin: sieve: /var/mail/mydomain/.dovecot.sieve sieve_global_path: /var/lib/dovecot/sieve/default.sieve sieve_dir: /var/mail/mydomain/sieve sieve_global_dir: /var/lib/dovecot/sieve/global/ For testing purposes I created a very simple /var/mail/mydomain/.dovecot.sieve with the following content: require ["fileinto", "regex"]; if address :is "from" "test(a)test.de" { fileinto "INBOX.Webi"; stop; } Then I sent a mail from test(a)test.de (the real address is ommitted here) to my mail account, but the mail is not moved to the subfolder Webi. In the log files there's no single hint what's going on. And in /var/mail/mydomain there's no .dovecot.sieve.log file. This directory is owned by popuser and that user has rights for reading and writing to this directory (and read rights for .dovecot.sieve), therefore it should not be a rights problem. Does anybody has suggestions what could be the cause of this? Sincerely, Steven

[Dovecot] Released Pigeonhole Sieve v0.1.17 for Dovecot v1.2.12
by Stephan Bosch 19 Jun '10

19 Jun '10

Hello Dovecot users, The new Dovecot v1.2 release is a good occasion to release a new Pigeonhole Sieve package with some relatively minor bug fixes. Changelog Sieve v0.1.17: - Made sure source code positions for compiler messages are recorded at start of tokens. - Fixed a few potential memory leaks in the Sieve compiler and the spam/virustest extensions. - Made command line tools return proper exit status upon failure. The release is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.17.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.17.tar.gz.sig Refer to http://pigeonhole.dovecot.org for more information. Have fun testing the new releases and don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

19 Jun '10

http://dovecot.org/releases/1.2/dovecot-1.2.12.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.12.tar.gz.sig Some of the most important fixes since v1.2.11: - deliver: Don't crash when a message with Auto-submitted: header gets rejected. - lib-storage: Fixed header searches to work correctly when there are multiple headers with same name. - dict client: Disconnect from dict server after 1 second of idling. - dict: If process crashed, it wasn't automatically restarted - dict file: If dict file's group permissions equal world permissions, don't try to change its gid. - maildir: Fixed a memory leak when copying with hardlinks. - maildir: Expunging last messages may have assert-crashed if their filenames had just changed.

[Dovecot] Dovecot 2.0 auth socket error
by Tim Traver 18 Jun '10

18 Jun '10

Hi Timo, ok, when dovecot starts up, it creates the socket files in /usr/local/var/run/dovecot for the auth and a variety of other socket stuff you have going on. It creates these socket files with root ownership. But I have in the config files that dovecot is running as a particular user (in this case uid100 and gid100) to match the global mail systems needs. I use qmail as the delivery agent, and when qmail envokes deliver, I get the following errors in the qmail log files : @400000004c1b18f22ea7a05c delivery 1497: deferral: lda:_Error:_userdb_lookup:_connect(/usr/local/var/run/dovecot/auth-userdb)_failed:_Permission_denied_(euid=100(sn)_egid=100(sn)_missing_+w_perm:_/usr/local/var/run/dovecot/auth-userdb,_euid_is_not_dir_owner)/lda:_Fatal:_Internal_error_occurred._Refer_to_server_log_for_more_information./ Now, from what I can tell, this is complaining that the socket doesn't have write permission for the group, because it is owned by root and created with only 600 permissions...I can chmod the file to add the rw for the group, and then it appears to start working ok, but if I stop and start dovecot, it will only re-create those files with the 600 permissions... It appears that this is not happening in the version 1.2.11 code base as I this machine is a new one that I am testing 2.0 code on... Am I missing a proper setting somewhere? here is my dovecot -l : # 2.0.beta6: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.0-RELEASE-p3 i386 auth_username_format = %Lu auth_username_translation = %@ auth_verbose = yes disable_plaintext_auth = no dotlock_use_excl = yes first_valid_uid = 100 listen = * lock_method = dotlock log_path = /local/logs/dovecot.errors mail_gid = 100 mail_location = maildir:%h/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_uid = 100 mmap_disable = yes passdb { args = /bin/checkpassword_dovecot_auth driver = checkpassword } plugin { quota = maildir sieve = ~/.dovecot.sieve sieve_dir = ~/Maildir/sieve } protocols = imap pop3 managesieve quota_full_tempfail = yes ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = prefetch } userdb { args = /bin/checkpassword_dovecot_deliver driver = checkpassword } verbose_proctitle = yes protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { mail_plugins = quota sieve } protocol imap { mail_plugins = quota imap_quota } Thanks, Tim.

[Dovecot] strange regex sieve filter error
by Tim Traver 18 Jun '10

18 Jun '10

Hi all, ok, I'm getting an error produced by the following sieve file : require ["fileinto","copy"]; # rule:[SPAM-TAG] if allof ( header :regex "Subject" "^\\[SPAM-TAG\\]") { fileinto "SPAM-TAG"; stop; } and I'm getting the following error in the dovecot delivery log : main_script: line 3: error: unknown tagged argument ':regex' for the header test (reported only once at first occurence). main_script: error: validation failed. But I looked up the syntax, and tried to figure out why this is getting the error. I guess I just don't quite know what this error means... I know that the value that it is trying to match is kind of strange, but it is a regular expression, so it should work... Thanks, Tim.

[Dovecot] Problem configuring rawlog with 2.0beta6
by Mark Sapiro 18 Jun '10

18 Jun '10

The initial problem I was seeing after upgrade from 2.0beta5 to 2.0beta6 was error messages from my Android phone K9 client that dovecot was reporting -1 messages in various mailboxes. These mailboxes do have the special "Mail System Internal Data" message in them. In trying to get more information for debugging, I tried toenable rawlog using the same configuration I used successfully with 2.0beta5, namely: service imap { executable = imap imap-postlogin } service imap-postlogin { executable = script rawlog unix_listener imap-postlogin { } } (full dovecot -n below), but instead of successful rawlog writes, I got the following log messages: Jun 16 19:46:36 sbh16 dovecot: script: Fatal: Client not compatible with this binary (connecting to wrong socket?) Jun 16 19:46:36 sbh16 dovecot: imap: Error: fd_read(/usr/local/var/run/dovecot/imap-postlogin) failed: disconnected So the first question is how do I configure rawlog for 2.0beta6? And the next question is why the "-1 messages".

Hello, I have been using successfully Dovecot 1.1.x for about a year now. It has been very stable. Now I'm uprading that same system to newer and more powerful hardware and I was wondering whether it is good idea or not to switch to Dovecot 1.2.x series. Could anybody direct me to feature comparision document or explain here main differences betweeen thos two branches? -- Veiko

[Dovecot] LDA to address extensions
by Martijn de Munnik 17 Jun '10

Hi List, I'm trying to make dovecot deliver messages to sam+extension(a)example.com to the imap folder 'extension' of the user 'sam'. I've configured postfix with these dovecot as LDA: mailbox_command = /opt/redknot/libexec/dovecot/deliver -f "$SENDER" -d "$USER" -m "$EXTENSION" -a "$RECIPIENT" recipient_delimiter = + Sam is a local system user so I don't want to use virtual_transport (I think). I've read http://wiki.dovecot.org/LDA/Postfix but so far without success. # 1.2.11: /etc/opt/redknot/dovecot.conf Warning: There is no way to login to this server: disable_plaintext_auth=yes, ssl=no, no non-plaintext auth mechanisms. # OS: SunOS 5.11 sun4v log_path: /var/log/dovecot.log ssl: no login_dir: /opt/redknot/var/run/dovecot/login login_executable: /opt/redknot/libexec/dovecot/imap-login login_max_processes_count: 10 max_mail_processes: 10 mail_location: maildir:~/Maildir lda: postmaster_address: postmaster(a)redknot.nl mail_plugins: sieve mail_plugin_dir: /opt/redknot/lib/dovecot/lda sendmail_path: /usr/sbin/sendmail auth_socket_path: /opt/redknot/var/run/dovecot/auth-master auth default: passdb: driver: pam args: other userdb: driver: passwd socket: type: listen master: path: /opt/redknot/var/run/dovecot/auth-master mode: 384 plugin: sieve_before: /etc/opt/redknot/sieve/before sieve_after: /etc/opt/redknot/sieve/after I know about the warning, this dovecot is only used as LDA, not for imap or pop3. thanks, Martijn YoungGuns Kasteleinenkampweg 7b 5222 AX 's-Hertogenbosch T. 073 623 56 40 F. 073 623 56 39 www.youngguns.nl KvK 18076568 YoungGuns Kasteleinenkampweg 7b 5222 AX 's-Hertogenbosch T. 073 623 56 40 F. 073 623 56 39 www.youngguns.nl KvK 18076568

[Dovecot] \Noselect on virtual folders
by Matthias Rieber 17 Jun '10

17 Jun '10

Hi, I've some virtual folders which seem a bit odd when they are listed. a LIST "virtual.spam." "*" * LIST (\Noselect \HasNoChildren) "." "virtual.spam." * LIST (\HasNoChildren) "." "virtual.spam.unchecked" * LIST (\Noselect \HasChildren) "." "virtual.spam.disagree" * LIST (\HasNoChildren) "." "virtual.spam.disagree.dspam" * LIST (\HasNoChildren) "." "virtual.spam.disagree.spamassassin" a OK List completed. This seems ok, virtual.spam and virtual.spam.disagree can't contain mails. I'm wondering if virtual.spam should have the flag \HasChildren instead if \HasNoChildren, but this doesn't cause trouble... a LIST (SUBSCRIBED) "virtual.spam." "*" * LIST (\Subscribed \Noselect) "." "virtual.spam.disagree.spamassassin" * LIST (\Subscribed \Noselect) "." "virtual.spam.disagree.dspam" * LIST (\Subscribed \Noselect) "." "virtual.spam.unchecked" a OK List completed. When I list the folder with (SUBSCRIBED), the virtual folders are all flagged with \Noselect. This appears at all virtual folders. All other folders don't have the \Noselect flag. On the Nokia N900 I can't enter all virtual folders. The log shows that the n900 always list the folders with (SUBSCRIBED). Is this listing the expected behaviour? regards, Matthias

[Dovecot] Shared mailboxes errors
by Nikita Koshikov 17 Jun '10

17 Jun '10

Hello list, I'm implementing shared mailboxes on live system and after enabling acl plugin I got errors in my log: Jun 17 15:50:33 dict: Error: sql dict iterate: Invalid/unmapped path: shared/shared-boxes/anyone/ I have no clue why this happening, users don't know about new functionality they just use imap as before. Also dict database begin to fill up by records like: select * from user_shares; user@domain.com|admin@domain.com|1 But user don't use setacl command. Searching for the list gave http://www.dovecot.org/list/dovecot/2009-April/038664.html , but question seemed still open. So, can someone give point how to fix\avoid this ? One more question, on live system it's hard to debug dovecot with mail_debug=yes for all users, can this option be turn on for individual user? or maybe mail_debug stream can be redirected also for individual user ?

[Dovecot] basic conf error? v1.2.11
by Justin Krejci 17 Jun '10

17 Jun '10

I just downloaded 1.2.11 and compiled from source including mysql support and using default directory locations. I walked thru the included example conf file and tweaked it out and get an invalid configuration file. I trimmed out all of the commented sections to make the non-default config super easy to navigate during troubleshooting. Remaining config which gives an error of "unknown setting: mechanisms" so I switched it to auth_mechanisms and then get the following when starting dovecot: Error: Error in configuration file /usr/local/etc/dovecot.conf line 18: Unknown section type (section changed in /usr/local/etc/dovecot.conf at line 14) Fatal: Invalid configuration in /usr/local/etc/dovecot.conf ##################### protocols = imap pop3 listen = <SCRUBBED IP> disable_plaintext_auth = no ssl = no login_processes_count = 100 login_max_processes_count = 500 login_max_connections = 512 login_greeting = DovecotProxy08 ready. protocol imap { } protocol pop3 { } protocol lda { } #LINE 14 auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@/$!&\ auth default { mechanisms = plain passdb sql { #LINE 18 args = /usr/local/etc/dovecot-sql.conf } userdb sql { args = /usr/local/etc/dovecot-sql.conf } user = root } dict { } plugin { } ##################### Any ideas what is wrong here? It seems like the example conf file is not correct. Yes the dovecot-sql.conf file exists.

[Dovecot] ZFS Index corruption and Connection reset by peer
by Philippe Chevalier 17 Jun '10

17 Jun '10

Hello, I'm currently using dovecot 1.2.11 on FreeBSD 8.0 with ZFS filesystems. So far, so good, it works quite nicely, but I have a couple glitches. Each user has his own zfs partition, mounted on /home/<user> (easier to set per user quotas) and mail is stored in their home. From day one, when people check their mail via imap, a lot of indexes corruption occured : dovecot: IMAP(<user>@domain.org): Corrupted transaction log file /home/<user>/Mail/Maildir/INBOX/dovecot.index.log seq 13: record size too small +(type=0x0, offset=5560, size=0) (sync_offset=5652) dovecot: IMAP(<user>@domain.org): fscking index file /home/<user>/Mail/Maildir/INBOX/dovecot.index dovecot: IMAP(<user>@domain.org): /home/<user>/Mail/Maildir/INBOX/dovecot.index log position went backwards (13,132 < 13,5560) dovecot: IMAP(<user>@domain.org): Transaction log file /home/<user>/Mail/Maildir/INBOX/dovecot.index.log: marked corrupted etc, etc... After some digging, I "solved" this problem with mmap_disable = yes in dovecot.conf. Index corruption doesn't seem to occur anymore. Is this normal? I thought this problem occured only on NFS filesystem and eventually on old versions of ZFS. Hasn't this been fixed? Is there an option in ZFS that would allow mmap calls without corruption. Has it something to do with compression ? The options of the zfs filesystem are : zhome/username type filesystem - zhome/username creation Thu Mar 18 11:10 2010 - zhome/username used 750M - zhome/username available 61.0G - zhome/username referenced 750M - zhome/username compressratio 1.20x - zhome/username mounted yes - zhome/username quota none default zhome/username reservation none default zhome/username recordsize 128K default zhome/username mountpoint /usr/home/username inherited from zhome zhome/username sharenfs off default zhome/username checksum on default zhome/username compression lzjb inherited from zhome zhome/username atime off inherited from zhome zhome/username devices on default zhome/username exec on default zhome/username setuid on default zhome/username readonly off default zhome/username jailed off default zhome/username snapdir hidden default zhome/username aclmode groupmask default zhome/username aclinherit restricted default zhome/username canmount on default zhome/username shareiscsi off default zhome/username xattr off temporary zhome/username copies 1 default zhome/username version 3 - zhome/username utf8only off - zhome/username normalization none - zhome/username casesensitivity sensitive - zhome/username vscan off default zhome/username nbmand off default zhome/username sharesmb off default zhome/username refquota none default zhome/username refreservation none default zhome/username primarycache all default zhome/username secondarycache all default zhome/username usedbysnapshots 0 - zhome/username usedbydataset 750M - zhome/username usedbychildren 0 - zhome/username usedbyrefreservation 0 - Other problem, that I have been unable to solve so far, is that a lot of entries show up in my logs about : dovecot: imap-login: net_disconnect() failed: Connection reset by peer It doesn't seem to have any adverse effect, except it's filling up the logs. It seem to appear when a client closes the imap connection? Is there a way to suppress this error? Regard P.C.

[Dovecot] BUG Dovecot 1.0.15 and Apples Mail.app
by Gerhard Waldemair 17 Jun '10

17 Jun '10

Is there anyone using Apple´s Mail.app to collect the mails via IMAP or IMAPS ? I found a funny bug in Debian Lennys Dovecot Version. (still v. 1.0.15) When I get my Mails via IMAP or IMAPS and define a Rule in Mail.app to move the eMail to s specific folder I will find the mail 2 times in the folder. After a minute or so the double Mail disappears. I have tried it with other programs like Thunderbird. There everything works, v1.0 too. Now I have updatet Dovecot from 1.0 to 1.2 from Backports and everything works great now !!!!! Regards, Gerhard PS in Squeeze Dovecot is Version 1.2

[Dovecot] Ok with a bit more wiki reading ...
by Chuck McManis 17 Jun '10

17 Jun '10

So if I want to run dovecot from tcpserver it seems like I can simply run `pop3-login --ssl` from tcpserver (its sort of like running it from inetd) and it says it will 'talk to dovecot'. Can I disable all listeners in dovecot then? Will is still talk to it? Trying some experiments now ... --Chuck

[Dovecot] Migrating from CommunigatePro to Dovecot - anyone done this?
by Gavin Lawrie 17 Jun '10

17 Jun '10

Apologies if this is in the archive - did look but couldn't find it. Does anyone have any experience of migrating from CommunigatePro to Dovecot? We currently run CGP 5.3.4, supporting a small system (20 or so users, one domain). We've been using it for years, and have a mixed bag of MailDir and mbox folders accessed via IMAP clients. Some users have large mail accounts (15GB total). We're looking to move as CGP is evolving into a complex "Messaging Centre" application (PBX, SIP, Mail, Groupware, Portals etc.) which we don't need / use. I had a look on the Dovecot Wiki and under migration are discussions about various other mail systems, but I don't know enough about these to tell if they would also apply to CGP. Any thoughts / suggestions would be welcomed. Thanks Gavin. * Balanced Scorecard Training from 2GC: Next course 16th July 2010 in the UK.

[Dovecot] search bug?
by Pozsar Balazs 16 Jun '10

16 Jun '10

Hi all, I have emails with multiple Delivered-To: headers in them. The problem is that the SEARCH command only searches in the first instances. For example: 1 FETCH 14557 BODY[HEADER.FIELDS (Delivered-To)] * 14557 FETCH (BODY[HEADER.FIELDS (DELIVERED-TO)] {85} Delivered-To: pozsy(a)ojjektum.uhulinux.hu Delivered-To: szamlagyar(a)uhusystems.com ) 1 OK Fetch completed. 1 SEARCH HEADER Delivered-To szamlagyar(a)uhusystems.com * SEARCH 14589 1 OK Search completed (0.146 secs). You can see the meesage with the id 14557 _has_ a "Delivered-To: szamlagyar(a)uhusystems.com" header field, but the SEARCH does not find it, only another message. This is with dovecot 1.2.11. For the record, cyrus-imapd behaves as I would have expected, and I could not find anything relevant in the RFCs. Could anyone tell me if this is a bug, or how to search like I would want? Thanks, Balazs Pozsar

[Dovecot] New admin, not much success
by Chuck McManis 16 Jun '10

16 Jun '10

Hello, I'm trying to set up something fairly simple (famous last words) using Dovecot. I have a very small setup (just a dozen users) I'm using qmail as my MTA. I'm running FreeBSD 8.0 I've got qmail delivering into a file named 'Mailbox' in user's home directories. I prefer not to use Maildir delivery because from a shell its a PITA to get a Maildir aware MUA (I use /bin/mail when I'm attached locally) What I'm trying to do is configure an SSL only POP3 server so that folks can retrieve their email on the road without divulging their passwords. My backup scenario is to put VPN software on my user's clients and having them VPN into the network and then do un-encrypted POP3 from the VPN. I prefer not to do this as it means maintaining the VPN client as well. Users have a mix of MacOS, Windows, and Linux. So, I can't get dovecot to work at all. In an unusual turn about I got the SSL stuff working but not the mailbox handling. I'm running 2.0beta6 Output from dovecot -n ------------------------------------------------------------------------------------ # 2.0.beta6: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.0-RELEASE-p2 i386 nfs auth_debug = yes auth_verbose = yes default_internal_user = nobody default_login_user = nobody listen = * mail_full_filesystem_access = yes mail_location = mbox:/home/%u/:INBOX=/home/%u/ passdb { driver = pam } protocols = pop3 service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } service pop3 { process_limit = 1024 } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } ----------------------------------------------------------------------- A typical failure looks like this in maillog: Jun 15 22:19:20 eeebox dovecot: master: Dovecot v2.0.beta6 starting up Jun 15 22:20:29 eeebox dovecot: pop3-login: Login: user=<cmcmanis>, method=PLAIN, rip=66.125.189.27, lip=66.125.189.30, mpid=78871, TLS Jun 15 22:20:29 eeebox dovecot: pop3(cmcmanis): Error: Opening INBOX failed: Mailbox isn't selectable Jun 15 22:20:29 eeebox dovecot: pop3(cmcmanis): Error: Couldn't open INBOX: Mailbox isn't selectable Jun 15 22:20:29 eeebox dovecot: pop3(cmcmanis): Couldn't open INBOX top=0/0, retr=0/0, del=0/0, size=0 -------------------------------------------------------------- Home directories are mounted via NFS and root doesn't have access, but if dovecot accesses the Mailbox as the user it should work fine. I'm about ready to start hacking in additional logging into mail-storage.c to figure out what "mailbox isn't selectable" means. --Chuck

[Dovecot] Logout after SSL/TLS negociation
by bmfr 16 Jun '10

16 Jun '10

Hi All, I've set up Dovecot to use my signed SSL certificate and IMAP client is using STARTTLS on port 143 without secure authentication. The TLS negociation process seems to go through ok but once the negociation is finished the client sends an IMAP LOGOUT message; he does not try to authenticate, below is the Dovecot's info log: dovecot: 2010-06-15 15:37:01 Info: auth(default): new auth connection: pid=3932 dovecot: 2010-06-15 15:37:03 Info: imap-login: Aborted login (0 authentication attempts): rip=130.100.32.54, lip=10.0.3.3, TLS I've decrypted the TLS negociation thanks to Wireshark (in SSL preferences I added the certificate's private key to decode the stream between client and server) but unfortunately it does not say why the client is sending the LOGOUT command. Do you have an idea of what could be wrong in my server set up? What debugging process would you advise me to follow? Thanks a lot for your precious help.

[Dovecot] A new director service in v2.0 for NFS installations
by Timo Sirainen 16 Jun '10

16 Jun '10

As http://wiki.dovecot.org/NFS describes, the main problem with NFS has always been caching problems. One NFS client changes two files, but another NFS client sees only one of the changes, which Dovecot then assumes is caused by corruption. The recommended solution has always been to redirect the same user to only a single server at the same time. User doesn't have to be permanently assigned there, but as long as a server has some of user's files cached, it should be the only server accessing the user's mailbox. Recently I was thinking about a way to make this possible with an SQL database: http://dovecot.org/list/dovecot/2010-January/046112.html The company here in Italy didn't really like such idea, so I thought about making it more transparent and simpler to manage. The result is a new "director" service, which does basically the same thing, except without SQL database. The idea is that your load balancer can redirect connections to one or more Dovecot proxies, which internally then figure out where the user should go. So the proxies act kind of like a secondary load balancer layer. When a connection from a newly seen user arrives, it gets assigned to a mail server according to a function: host = vhosts[ md5(username) mod vhosts_count ] This way all of the proxies assign the same user to the same host without having to talk to each others. The vhosts[] is basically an array of hosts, except each host is initially listed there 100 times (vhost count=100). This vhost count can then be increased or decreased as necessary to change the host's load, probably automatically in future. The problem is then of course that if (v)hosts are added or removed, the above function will return a different host than was previously used for the same user. That's why there is also an in-memory database that keeps track of username -> (hostname, timestamp) mappings. Every new connection from user refreshes the timestamp. Also existing connections refresh the timestamp every n minutes. Once all connections are gone, the timestamp expires and the user is removed from database. The final problem then is how multiple proxies synchronize their state. The proxies connect to each others forming a connection ring. For example with 4 proxies the connections would go like A -> B -> C -> A. Each time a user is added/refreshed, a notification is sent to both directions in the ring (e.g. B sends to A and C), which in turn forward it until it reaches a server that has already seen it. This way if a proxy dies (or just hangs for a few seconds), the other proxies still get the changes without waiting for it to timeout. Host changes are replicated in the same way. It's possible that two connections from a user arrive to different proxies while (v)hosts are being added/removed. It's also possible that only one of the proxies has seen the host change. So the proxies could redirect users to different servers during that time. This can be prevented by doing a ring-wide sync, during which all proxies delay assigning hostnames to new users. This delay shouldn't be too bad because a) they should happen rarely, b) it should be over quickly, c) users already in database can still be redirected during the sync. The main complexity here comes from how to handle proxy server failures in different situations. Those are less interesting to describe and I haven't yet implemented all of it, so let's just assume that in future it all works perfectly. :) I was also thinking about writing a test program to simulate the director failures to make sure it all works. Finally, there are the doveadm commands that can be used to: 1) List the director status: # doveadm director status mail server ip vhosts users 11.22.3.44 100 1312 12.33.4.55 50 1424 1) Add a new mail server (defaults are in dovecot.conf): # doveadm director add 1.2.3.4 2) Change a mail server's vhost count to alter its connection count (also works during adding): # doveadm director add 1.2.3.4 50 3) Remove a mail server completely (because it's down): # doveadm director remove 1.2.3.4 If you want to slowly get users away from a specific server, you can assign its vhost count to 0 and wait for its user count to drop to zero. If the server is still working while "doveadm director remove" is called, new connections from the users in that server are going to other servers while the old ones are still being handled.

[Dovecot] Sieve doesn't appear to be active
by Darek M 16 Jun '10

16 Jun '10

I'm hoping that this isn't something stupid and that I'm not wasting bandwidth here, but I'm stuck and don't know any further ways of debugging this. And most non-documentation, end-user created info I find is for 1.0 with cmusieve. Running Dovecot 1.2.11 on Fedora Core 12. Added 'sieve' to 'mail_plugins'. Have enabled verbose logging with 'mail_debug = yes'. But I'm not seeing anything in the logs relating to sieve, and the sieve script I point to isn't being compiled (no .log file). Everything else works fine, this is a production system where I'm trying to add sieve support. What steps can I take to troubleshoot?

[Dovecot] passwd-file management utility
by Phil Howard 15 Jun '10

15 Jun '10

I'm now putting together tools/documentation to manage/administer the mail server, including, of course, managing users. Round one will be command line tools. In order to avoid re-invention, I was looking around for existing tools. I really cannot find any. So it seems I will be developing them. The first will be the one to manage users in the passwd-file format. So I'm just asking around if anyone has heard of such tools somewhere Google isn't finding (it does find lots of generic pages with the keywords used in other contexts). If not, I'll be building my own (and this will be for passwd-file format for the userdb/passdb),

by Greg Pearson 15 Jun '10

15 Jun '10

Hi, I have just switched to Maildir, and I have noticed something. Even though it works properly, I have noticed that a file named /var/mail/user with 0 bytes length is still created. Is this normal? I use sendmail+procmail+dovecot. I have also tried the combined procmail+deliver approach with the same results. I also use a global /etc/procmailrc. Thank you

Hi all, ok, I am updating to the 2.0 way of doing things and have managed to get everything set up right, except I am getting the following errors when attempting to use managesieve with our webmail client (roundcube) that I didnt get when using dovecot 1.2.11...

[Dovecot] convert Plugin Error

I am getting an error when using the convert plugin for dovecot.

It continues to add a message from the mbox to Maildir format, creating duplicates every time I check my email. I can fix it by deleting mail-converted, but I don't want this to happen to other users on the system. Does anyone have a clue as to why it's doing this, and what I can do to fix it?

[Dovecot] Ubuntu upgrade to 10.04 --> dovecot no longer working
by HenkR 14 Jun '10

14 Jun '10

Hi, Last year I installed dovecot on my Ubuntu V9 system 64 bit system. I use it to store emails from several clients in the LAN using IMAP. Last week I upgraded to Ubuntu 10.04. Now Dovecot is no longer working. It started with messages about sieve, so I disabled sieve in the configuration file (did not use it in the past, don't know what it is). Dovecot can now be started without errors or warnings, but I cannot connect in the client. I get a message saying "could not connect to server: connection refused". Can anybody help? kind regards, Henk -- View this message in context: http://old.nabble.com/Ubuntu-upgrade-to-10.04---%3E-dovecot-no-longer-worki… Sent from the Dovecot mailing list archive at Nabble.com.

http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta6.tar.gz http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta6.tar.gz.sig Unfortunately this still isn't rc1 yet, but the next one will be, I promise :) Basically all of the important changes are done now. The TODO list for rc1 is: - Test and fix dsync bugs - Finish director - Add man pages started by Pascal Volk. BTW. He asked for some feedback about them, but got only one reply: http://dovecot.org/list/dovecot/2010-June/049438.html I've also read through and answered nearly all of my email backlog. If you haven't gotten a reply, resend the mail. Some changes since beta5: - Added director: http://blog.dovecot.org/2010/05/new-director-service-in-v20-for-nfs.html - IMAP: Added STATUS (X-VSIZE) command for easily getting mailbox's virtual size. - Lots and lots of doveadm improvements and new commands - Postlogin scripts now need to be executed using "script-login", not "script" binary. - Quota warnings are executed now asynchronously using the new script binary. See http://hg.dovecot.org/dovecot-2.0/rev/a179fcbbf960 - Added passdb static for proxying and similar configurations - TLS SNI configuration must now be done using local_name {} blocks, not local {} - lib-storage plugin API changes, external plugins must be updated to work correctly - Lots of fixes

[Dovecot] Shared Mailbox Questions
by Chris Hobbs 11 Jun '10

11 Jun '10

Hi All, I've pored over the wiki, read through the archive, and have what I believe should be a working set-up, but I can't seem to get my shared namespace to work correctly. Any guidance would be much appreciated. I started off using a flat file for acl_shared_dict and ran into the same problem recently reported with the shared-database file getting chown'd to the first user to touch it with 0600 permissions. So I thought I'd give it a whirl with sqlite. Here are the (hopefully) relevant bits from dovecot -n (the entire output is posted below). This is dovecot 1.2.9 running on a freshly installed ubuntu 10.4 server: namespace: type: shared separator: / prefix: shared/%%u/ location: maildir:/home/staff/%%n/Maildir:INDEX=~/Maildir/shared/%%u list: children plugin: acl_shared_dict: proxy::acl dict: acl: sqlite:/etc/dovecot/acl-shared-dict.conf acl-shared-dict.conf looks like this: connect = /home/staff/dovecot/acl-shared-ns.sqlite map { table = acl_shared_ns pattern = shared/shared-boxes/user/$to/$from value_field = has_visible_folders fields { from_user = $from to_user = $to } } /home/staff/dovecot/acl-shared-ns.sqlite is set 0666, and I can add records to it from the sqlite command line as a normal user. The table was created with: CREATE TABLE acl_shared_ns (from_user, to_user, has_visible_folders, PRIMARY KEY (from_user) ON CONFLICT REPLACE); When I attempt to SETACL from a telnet imap session, I get the following errors in mail.err: Jun 9 22:10:23 imap2 dovecot: dict: dict sql iterate failed: file is encrypted or is not a database Jun 9 22:10:23 imap2 dovecot: dict: dict sql iterate failed: file is encrypted or is not a database Jun 9 22:10:23 imap2 dovecot: dict: sqlite: exec(INSERT INTO acl_shared_ns (has_visible_folders,to_user,from_user) VALUES ('1','chobbs','IOchoa')) failed: file is encrypted or is not a database (26) Jun 9 22:10:23 imap2 dovecot: IMAP(IOchoa): read(/var/run/dovecot/dict-server) failed: Remote disconnected Jun 9 22:10:23 imap2 dovecot: IMAP(IOchoa): acl: dict commit failed Jun 9 22:10:23 imap2 dovecot: dovecot: child 8268 (dict) killed with signal 11 (core dumps disabled) Running that same "INSERT INTO..." as the IOchoa user from the sqlite command line works just fine. At this point any further deleteacl or setacl commands simply hang, presumably because there's no longer a running dict process.

[Dovecot] question about rpc quota reporting 1.2.11
by Tom Lieuallen 11 Jun '10

11 Jun '10

Timo, thank you for the reply to my question about shared folders yesterday. I'm now trying to get quota reporting working consistently. This is with dovecot 1.2.11 in solaris 10 sparc. We have local quotas for the mail spool (/a1) and quotas for home directories. All are UFS and have rpc (rquota) working fine. With just this: protocol imap { mail_plugins = quota imap_quota } My mail client (thunderbird 3.0.4) reported the home directory quota. So then I added this: plugin { quota = fs:INBOX:mount=/a1 quota2 = fs:Home:mount=%h } First, I had to make /a1/quotas world readable, otherwise I'd get this error: open(/a1/quotas) failed: Permission denied I'm getting the same type of error with the quota2 line now: open(/nfs/rack/u4/quotas) failed: Permission denied Since the home directory quota worked without the plugin configuration, my guess is that the plugin config is not using rpc. I can't find any way to force it to use rpc. Again, if I make that 'quotas' file world readable (which I believe isn't good practice), dovecot stops complaining. Also, what should I expect to see on the client? Will dovecot report only one quota (the one that's closer to the limit), or will it report both? I've only seen the first quota in thunderbird, but that could easily be a client issue. thank you Tom Lieuallen Oregon State University

[Dovecot] null errors from 2.0.beta5
by Mike Abbott 11 Jun '10

11 Jun '10

When my dovecot-2.0.beta5 auth module logs a 552-byte debug message, the message is split into two lines and also a null error message: Wed Jun 9 23:44:29 gromit dovecot[58892]: auth: Error: I think this has to do with the use of PIPE_BUF (512) sized buffers in the logging code, and the !line_is_ok() case in i_failure_parse_line(). Could you please remove the null error message? Just a nuisance, nothing serious. Thanks.

[Dovecot] lazy-expunge acl bug?
by Martin Ott 11 Jun '10

11 Jun '10

Hi, we've defined a public namespace "shared" and use the acl and lazy-expunge plugins among others. The problem is, that a mailbox is deleted by the DELETE-command without the x-flag to be set (# 1.2.9): a myrights shared/aclDeleteTest * MYRIGHTS "shared/aclDeleteTest" lrsed a OK Myrights completed. b delete shared/aclDeleteTest b OK Delete completed. c myrights shared/aclDeleteTest c NO Mailbox doesn't exist: aclDeleteTest This behavior should be different and the mailbox should not be deleted, should it? Is there a fast workaround? Without the e-flag, mailboxes can't be deleted. But as some users should be allowed to use the expunge operation, it's no option to remove the e-flag... thx Martin

[Dovecot] problems with shared mailboxes and other general issues
by Tom Lieuallen 11 Jun '10

11 Jun '10

I'm also having beginner's troubles with shared mailboxes with dovecot 1.2.11. I've used the TestInstallation instructions for connecting to the imap port via openssl and issuing the setacl/getacl commands. Those appear to be fine. I'm having real difficulty with the acl_shared_dict configuration. I'd prefer to just use a flat file, as I don't anticipate using shared folders very frequently. I don't need a database and would greatly prefer not to have a dependency on our database service. So, with this setting: acl_shared_dict = file:/private/dovecot/var/etc/shared-mailboxes The '../var/etc' directory is something like 755. I have to create the file first and make it 666. When it is updated, ownership & permissions are changed such that the user giving acl permissions then owns the file and it's 600. I tried setting it back to 644 afterward, so other users could read it, but they tried setting a lock in that dir as well. I tried this: acl_shared_dict = file:/private/dovecot/var/etc/shared-list/shared-mailboxes-%u Then I made shared-list have '1777' permissions. Permissions-wise, this will now work, including locks, but I'm guessing this is just plain wrong and I still can't verify access. My second choice was to use sqlite for this acl_shared_dict, but, even though I compiled dovecot with sqlite support and 'ldd' shows that '../libexec/dict' is linked against sqlite libraries, when I tried this config: acl_shared_dict = sqlite:/private/dovecot/etc/acl-shared-dict.conf I get this, and dovecot fails to start up. EUnknown dict module: sqlite I question whether I can use sqlite for acl_shared_dict. Furthermore, in this vein, I don't really know what the shared namespace should even look like. I've been trying the imap commands LIST and MYRIGHTS to verify access, but there are simply no examples. I'd rather expect this to work: x myrights shared/fromuser/folder but all I get is mailbox doesn't exist. I know 'shared' is the namespace, but I just don't know how it should really be referred to. Personally, I can live without the acl_shared_dict (from what I understand). I don't need to see the shared path for subscription, I'd just manually add the folder path to the .subscriptions file for the handful of users that need it. I just don't think it's working, though. On a related note, I thought I'd increase debugging to see if that helped out any. When I change 'mail_debug' to 'yes', as soon as I issue the imap login command, it logs some stuff, then kicks me out. Jun 09 15:57:53 IMAP(tom2): Info: acl: initializing backend with data: vfile Jun 09 15:57:53 IMAP(tom2): Info: acl: acl username = tom2 Jun 09 15:57:53 IMAP(tom2): Info: acl: owner = 1 Jun 09 15:57:53 dovecot: Error: child 6000 (imap) killed with signal 11 (core dumps disabled) I would assume this error is causing my problems, but for all I know, it could be a side-effect of verbose debugging -- to just terminate. I see nothing about that in the docs, though. imap works fine without verbose logging, so I'm baffled. I have been frustrated by the shared namespace documentation. I've been through it again and again, but haven't found the answers I've been looking for. Here is the relevant configuration: namespace shared { location = mbox:%%h/mail/shared:INDEX=%%h/mail/shared/.imap # everything else defaults } protocol imap { mail_plugins = quota imap_quota acl imap_acl } protocol lda { mail_plugins = acl } plugin { acl = vfile acl_shared_dict = file:/private/dovecot/var/etc/shared-list/shared-mailboxes-%u }

[Dovecot] Question about directory hashing
by Javier de Miguel Rodríguez 11 Jun '10

11 Jun '10

Hello I have been reading http://wiki.dovecot.org/MailLocation and http://wiki.dovecot.org/Variables and I do not fully understand the directory hashing feature. I want to migrate > 70.000 users from Sun Messaging to Dovecot using imapsync. I have tested with mail_location=maildir:/buzones/us.es/%1Hu/%2.1u/%n but I get the following directory tree: `-- 0 |-- - |-- 1 |-- 2 |-- 3 |-- 8 |-- _ |-- a |-- ab |-- b |-- c |-- d |-- e |-- ev |-- f |-- g |-- h |-- i |-- ie |-- is |-- j |-- jb |-- jj |-- jp |-- js |-- k |-- l |-- m |-- mb |-- n |-- o |-- p |-- pp |-- q |-- r |-- rm |-- s |-- t |-- u |-- v |-- w |-- x |-- y `-- z The ideal directory layout should be the following: First directory level: Letters from a to z Second directory level: Numbers from 0 to 200 Third directory level: %n (username without @domain) How can I achive this directory layout (or other optimized for 70.000 users) . I use ext3 on Red Hat Enterprise Linux 5 with directory indexes on. Regards Javier de Miguel

[Dovecot] Fail2ban

I have fail2ban working for EVERYTHING else except dovecot. I have tried using my own custom regex in conjunction with the regex on the dovecot.org site. Neither are picked up by fail2ban and I'm trying to use an imminent attack agaist dovecot, going on now, to my advantage to see when I get the right regexp. Here are my current ones: failregex = .*dovecot: (?:pop3-login|imap-login): (?:Disconnected|Aborted login) $(?:auth failed, .* attempts|no auth attempts)$:.*rip=<HOST>,.* <<< this is my custom (?: pop3-login|imap-login): (?:Authentication failure|Aborted login \(auth failed|Aborted login \(tried to use disabled|Disconnected \(auth failed).*rip=(?P<host>\S*),.* <<< from dovecot.org .*warning:.\S*\[(?P<host>)\]: SASL.(?:PLAIN|LOGIN).authentication failed:.* Here is the current attack: Jun 10 17:18:10 mail dovecot: pop3-login: Disconnected (auth failed, 1 attempts): user=<rahul>, method=PLAIN, rip=113.12.82.71, lip=173.50.101.12 Can someone help me out a little?

[Dovecot] Evolution and Thunderbird do different things?
by Phil Howard 10 Jun '10

10 Jun '10

I'm trying both Evolution and Thunderbird on my IMAP server, and find that there are differences in how some things are done, between clients. Shouldn't there have been a standard way to do these things in the IMAP protocol? The first thing I noticed is that when deleting email from one client, it puts a "T" on the file name, leaving it where it is, and from the other client, it moves the mail to a ".Trash" directory on the server (and created a 2nd "Trash" folder ... so now I have 2 "Trash" folders, one with some deleted mail in it, and the other with some deleted mail in it). I'm not saying Dovecot has a problem here. But maybe IMAP the protocol does for not having a standard way to do things, and these clients, for not doing it the same way (if there is some standard somewhere). Any IMAP experts here know what the story is with this?

[Dovecot] Problem with LDAP query
by Aleix Dorca 10 Jun '10

10 Jun '10

Hi people, first message to this list. I've a problem with dovecot 1.0.15 (debian latest package) and an LDAP query. The situation is the following. My LDAP users have multiple mail addresses (field 'mail') and mail should be able to be sent to any of these and the mail should always end on the user's mailbox. This is not working for me now. My dovecot-ldap.conf relevant config shows: user-attrs = uid=user user_filter = (&(objectClass=posixAccount)(|(uid=%n)(mail=%u))) This correctly detects multiple addresses but mail always end in folder (from dovecot.conf): mail_location = maildir:/home/vmail/%n/Maildir So if user@domain gets a mail it ends in /home/vmail/user/Maildir but if the same user gets an email to user-alt@domain it ends in /home/vmail/user-alt/Maildir instead of /home/vmail/user/Maildir. I've been debugging and I get this on my mail.log file: Jun 10 12:41:29 horologium deliver(user-alt@domain): auth input: user-alt@domain Jun 10 12:41:29 horologium deliver(user-alt@domain): auth input: user=user Jun 10 12:41:29 horologium deliver(user-alt@domain): auth input: uid=5000 Jun 10 12:41:29 horologium deliver(user-alt@domain): auth input: gid=5000 Jun 10 12:41:29 horologium deliver(user-alt@domain): maildir: data=/home/vmail/user-alt/Maildir Jun 10 12:41:29 horologium deliver(user-alt@domain): maildir: root=/home/vmail/user-alt/Maildir, index=/home/vmail/user-alt/Maildir, control=, inbox= Since I'm in version 1.0.15 can't use the mailLocation with the $ substitution. Anyway, any help will be appreciated.

[Dovecot] converting from vm-pop3d
by Tim Uckun 09 Jun '10

09 Jun '10

Hello All. I am looking into an old server which is running vm-pop3d. This server is having problems because the pop3 server is taking up 100% of the CPU. I looked at the largest mailboxes and there are a handful over 20 megs in size, the largest one is 55megs, they are all mbox format (I think). I have been looking at the wiki and it looks like there is a perl script to make the mailboxes behave. There are also other scripts that try and convert mbox to maildir formats and from what I can gather dovecot can do this as well. Finally the dovecot in the fedora repos is 1.0.X and I notice that the latest in 1.2.X is there a more up to date dovecot RPM repo? I would appreciate any advice anybody can give me on how to proceed with this transition. Thank you in advance.

[Dovecot] Migration from Courier to Dovecot: is it recommended to "force" d.index* creation?
by Sandro Tosi 08 Jun '10

08 Jun '10

Hello, we are planning to migrate from Courier to Dovecot. We already know courier-dovecot-migrate.pl, that will convert UID list and subscriptions files to dovecot format, and we will run it in batch on all Maildir + enable it at login, once we do the switch But we are also wondering it it might be wise to "force" the creation of dovecot.index{,.cache} files at conversion-time. It seems that, at least, d.i.c is created at FETCH of a mail, i.e. reading it, but we do not want to "alter" mails status of our clients. Is there a way to create them in batch, or is it better to just let them be created once clients start accessing their mailboxes via dovecot? Thanks in advance, Sandro

[Dovecot] Problem after migrating from mbox to maildir and squirrelmail
by Wawan S 08 Jun '10

08 Jun '10

Hi all, I just finished migrating from mbox to maildir (and upgrade squirrelmail to the latest version) with some issue. We are using Postfix 2.3, Dovecot 1.2.7 and Squirrelmail 1.4.2. One of user report that suddenly all his Sent and Drafts emails were disapeared. After log in to webmail, I found out that there are 3 new folder called Drafts, Sent and Trash apart from Drafts,Sent,Trash underneath INBOX folder, and all his sent and draft emails were there. I thought I just move the email from Sent folder to the Sent underneath INBOX, but I was wrong. Now he got all sent emails in Sent items but after refreshed the webmail, INBOX wont open at all. it just blank but in the left side it said the amount of his email. what did i do wrong? is it something to do with the dovecot.index and index.cache or the uidlist? please enlighten me.... thank you Hendry

[Dovecot] dovecot transaction log permissions
by Jordan Tardif 08 Jun '10

08 Jun '10

So after some problems with NFS and transaction logs getting corrupted. Im tyring out storing them localy. via.. mail_location: maildir:~/Maildir:INDEX=/var/dovecot/indexes/%u the problem is with a large amount of users.. the indexes dir becomes huge with this setup. So a change to make this better is... mail_location: maildir:~/Maildir:INDEX=/var/dovecot/indexes/%d/%n to seperate the users dir's into domains. What seems to happen is dovecot creates the index's folder automaticly and its owned by that user.. eg.. drwx------ 3 10651674 2598184 4096 2010-06-02 19:08 domain.com this makes it so no other user of domain.com can get their transaction logs created cause the dir is owned by another user at that domain. Is there anyway around this? I see there used to be a umask option but that is gone in 1.2.x. -- Jordan Tardif DreamHost

[Dovecot] Questions about migration Sun Messaging -> Dovecot+Postfix+Ldap
by Javier de Miguel Rodríguez 07 Jun '10

07 Jun '10

Hello. We are planning a migration from Sun One Messaging Server to Dovecot+Postfix+Ldap. We are using Dovecot 1.2.11 with Sun One Directory Server 5.2 ldap (we will migrate to Directory Server 6.3.1) soon. In our University we have 65.000 students, 5.500 staff and 6.500 teachers. Our main ldap realm is dc=us,dc=es (us means University of Seville, Spain). We have two e-mail domains, @us.es (staff+teachers) and @alum.us.es (students). We use Sun One Directory Server to load data to our ldap from several sources (like Oracle databases, flat files, etc) Our ldap tree is like this: dc=us,dc=es | |----->ou=People,dc=us,dc=es // "special" users only used by apps | | |----->o=us.es,dc=us,dc=es // ldap branch for staff+teachers | | |----->o=alum.us.es,dc=us,dc=es // ldap branch for students A user id is unique, so there is only a "john_doe" in the ldap tree (I repeat, there is NOT uid=john_doe,o=us.es,dc=us,dc=es and uid=john_doe,o=alum.us.es,dc=us,dc=es). Below you will find a copy of the dovecot.conf and dovecot-ldap.conf. Our operating system is Red Hat Enteprise Linux 5 x64. These are our questions: 1) We are unable to make dbox work with quota, but we have no problem with maildir. Quota is stored in a ldap attibute called "mailQuota" 2) A user can be in different branches in the same time: for example, a teacher called pepito should be in the uid=pepito,o=us.es,dc=us,dc=es branch but if that teacher is also a student should have another ldap entry uid=pepitosurname,o=us.es,dc=us,dc=es. Our identity management is the piece of software that "promotes" a user in that case. How should we use "mail_location" to addres this? 3) We are planning to use two raid5 of 8 SAS 15.000 rpm disks for these mailboxes. We will use a "2.0, ajax-based webmail" like roundcube. Most of our users will use webmail (imap based). How many iops should we have in that enviroment? We would like to use dbox, but we are stuck in maildir because 1) 4) Some users could have their mailboxes "disabled". We use the following line: user_filter = (&(objectClass=inetorgperson)(uid=%n)(mailUserStatus=active)) but it does NOT work as expected. Any idea) 5) We are planning to use bacula to backup user mailboxes. Any known problem with this (i will ask in the bacula mailing list anyway) 6) I have read carefully perfomance in dovecot wiki. Can I use noatime in /etc/fstab safely with dovecot? Any perfomance hint apart from we already have in our config files? 7) When we set vacation messages they work but we see this error in the log: dovecot: deliver(jorgelp): file_dotlock_create(~/.dovecot.lda-dupes) failed: No such file or directory 8) When a user log in she uses his username "mary" (without @us.es or @alum.us.es) . Our dovecot search in all the ldap tree until it finds that uid. But we would like to store in our mail_location /buzones/us.es or /buzones/alum.us.es. How can we accomplish this? We should use the "upper branch name" as part of the mail_location. Thank you for your support (and for your patience).

[Dovecot] mangled user_attrs from LDAP
by markham breitbach 07 Jun '10

07 Jun '10

I have setup dovecot to allow users to login using their email address or uid and have found a strange behaviour when the user logs in using the email address for a "username". I am using OpenLDAP for a backend data store with a rather customized schema. This behaviour occurs for both POP3 and IMAP logins. For some users it works as expected, but for others the pass_attrs->user does not get mapped back to the uid, but remains the mailLocalAddress (dovecot-ldap.conf is attached at the end of this post). Here is an excerpt from the logs for a working and a malfunctioning user. In both cases the users were logged directly into the pop3 port (ie. telnet <mailserver> 110) and used the fully qualified email address as the user (ie. foo(a)ex.tld) Jun 02 13:23:19 pop3-login: Info: Login: user=<foo>, method=PLAIN, rip=64.247.129.10, lip=64.247.129.10, secured Jun 02 13:23:19 POP3(foo): Info: Loading modules from directory: /usr/local/lib/dovecot/pop3 Jun 02 13:23:19 POP3(foo): Info: Module loaded: /usr/local/lib/dovecot/pop3/lib10_quota_plugin.so Jun 02 13:23:19 POP3(foo): Info: Effective uid=14921, gid=2000, home=/nonexistent Jun 02 13:23:19 POP3(foo): Info: Quota root: name=User quota backend=maildir args= Jun 02 13:23:19 POP3(foo): Info: Quota rule: root=User quota mailbox=* bytes=0 messages=0 Jun 02 13:23:19 POP3(foo): Info: maildir: data=/var/mail/foo Jun 02 13:23:19 POP3(foo): Info: maildir++: root=/var/mail/foo, index=, control=, inbox=/var/mail/foo Jun 02 13:23:19 POP3(foo): Info: Namespace : Using permissions from /var/mail/foo: mode=0700 gid=-1 Jun 02 16:54:06 pop3-login: Info: Login: user=<bobs>, method=PLAIN, rip=199.247.84.12, lip=64.247.129.4 Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: Loading modules from directory: /usr/local/lib/dovecot/pop3 Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: Module loaded: /usr/local/lib/dovecot/pop3/lib10_quota_plugin.so Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: Effective uid=38538, gid=2000, home=/nonexistent Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: Quota root: name=User quota backend=maildir args= Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: Quota rule: root=User quota mailbox=* bytes=524288000 messages=0 Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: Quota rule: root=User quota mailbox=Trash bytes=52428800 messages=0 Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: Quota rule: root=User quota mailbox=Deleted Messages bytes=52428800 messages=0 Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: maildir: data=/var/mail/bob_smith(a)example.tld Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: maildir++: root=/var/mail/bob_smith(a)example.tld, index=, control=, inbox=/var/mail/bob_smith(a)example.tld Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: Namespace : Using permissions from /var/mail/bob_smith(a)example.tld: mode=0700 gid=-1 Jun 02 16:54:10 POP3(bob_smith(a)example.tld): Info: Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0 After much searching for anything different between these records, some tcpdumps showed that the problem occured when LDAP returned the attributes in a different order than they are requested in. In this sample, you can see the request for uid,homeDirectory,uidNumber,gidNumber,mailQuota and the values are returned in the order gidNumber, uid, uidNumber, homeDirectory. There is no mailQuota set for this user. 16:54:06.145597 IP mail.xxxxx.com.62929 > closest-ldap.ldap: P 14:261(247) ack 15 win 33304 <nop,nop,timestamp 1521221146 267819447> 0x0000: 4500 012b fd4d 4000 4006 b87a 40f7 8104 E..+.M@.@..z@... 0x0010: 40f7 8112 f5d1 0185 41e1 8b7d 5aea 01d9 @.......A..}Z... 0x0020: 8018 8218 8522 0000 0101 080a 5aab fe1a ....."......Z... 0x0030: 0ff6 99b7 3081 f402 0120 6381 ee04 0b64 ....0.....c....d 0x0040: 633d 322c 6463 3d73 7369 0a01 020a 0100 c=2,dc=ssi...... 0x0050: 0201 0002 0100 0101 00a0 8198 a317 040d ................ 0x0060: 6163 636f 756e 7473 7461 7475 7304 0661 accountstatus..a 0x0070: 6374 6976 65a3 1c04 1265 6d61 696c 6163 ctive....emailac 0x0080: 636f 756e 7453 7461 7475 7304 0661 6374 countStatus..act 0x0090: 6976 65a1 5fa3 2704 0375 6964 0420 626f ive._.'..uid..bo 0x00a0: 625f 6d61 6364 6f6e 616c 6440 6772 6561 b_xxxxxxxxx@xxxx 0x00b0: 7473 6c61 7665 6865 6c69 2e63 6f6d a334 xxxxxxxxxx.com.4 0x00c0: 0410 6d61 696c 4c6f 6361 6c41 6464 7265 ..mailLocalAddre 0x00d0: 7373 0420 626f 625f 6d61 6364 6f6e 616c ss..bob_xxxxxxxx 0x00e0: 6440 6772 6561 7473 6c61 7665 6865 6c69 x@xxxxxxxxxxxxxx 0x00f0: 2e63 6f6d 3035 0403 7569 6404 0d68 6f6d .com05..uid..hom 0x0100: 6544 6972 6563 746f 7279 0409 7569 644e eDirectory..uidN 0x0110: 756d 6265 7204 0967 6964 4e75 6d62 6572 umber..gidNumber 0x0120: 0409 6d61 696c 5175 6f74 61 ..mailQuota 16:54:06.147464 IP closest-ldap.ldap > mail.xxxxx.com.62929: P 15:142(127) ack 261 win 32942 <nop,nop,timestamp 267819449 1521221146> 0x0000: 4500 00b3 bb91 4000 4006 faae 40f7 8112 E.....@.@...@... 0x0010: 40f7 8104 0185 f5d1 5aea 01d9 41e1 8c74 @.......Z...A..t 0x0020: 8018 80ae b708 0000 0101 080a 0ff6 99b9 ................ 0x0030: 5aab fe1a 307d 0201 2064 7804 1663 6e3d Z...0}...dx..cn= 0x0040: 6773 6862 6f62 6d2c 6463 3d32 2c64 633d xxxbobx,dc=2,dc= 0x0050: 7373 6930 5e30 1304 0967 6964 4e75 6d62 ssi0^0...gidNumb 0x0060: 6572 3106 0404 3230 3030 3010 0403 7569 er1...20000...ui 0x0070: 6431 0904 0767 7368 626f 626d 3014 0409 d1...xxxbobx0... 0x0080: 7569 644e 756d 6265 7231 0704 0533 3835 uidNumber1...385 0x0090: 3338 301f 040d 686f 6d65 4469 7265 6374 380...homeDirect 0x00a0: 6f72 7931 0e04 0c2f 6e6f 6e65 7869 7374 ory1.../nonexist 0x00b0: 656e 74 ent I will spare you the packet dump, but in the cases where the login works correctly, LDAP returns the values in the same order that they are requested in. This behaviour has been found with both OpenLDAP: slapd 2.3.39 and OpenLDAP: slapd 2.4.17, and is consistent with standard LDAP behaviour (ie, there is no guaranteed ordering in the LDAP database). A brief look at the code, seems to indicate that the values are being pulled from the LDAP return struct in a step-wise manner, which could certainly put them out of sync with the request if it is assumed that they will always be returned in the same order....This is just based on a quick review of the code though, and not any detailed tracing.

[Dovecot] Expunge Logging Patch
by James Devine 07 Jun '10

07 Jun '10

I have made some changes to the expunge logging as client->mailbox is set to NULL prior to one of the relevant calls. The change leaves mailbox in the function now and adds client. The modified patch to 1.2.11 is included.

[Dovecot] Ignoring the quota by the LDA?
by Holger Richter 07 Jun '10

07 Jun '10

Is it possible to configure dovecot in a manner that only the imap process respects the quota, and the local delivery ignores completely the quota? I think it should happen if I don't activate the quota plugin in the lda section but only in the imap section. protocol lda { ... # mail_plugins = ... } protocol imap { ... mail_plugins = quota imap_quota ... } Will it work or will it result in a big mess? I've the aim that a mail will never be rejected because the recipient is over his/her quota. Regards, Holger

[Dovecot] Problems with the IMAP proxy after upgrading from dovecot 1.1.16 to 1.211
by Holger Richter 07 Jun '10

07 Jun '10

We have frequent timeout problems after upgrading our imap servers from dovecot 1.1.16 to dovecot 1.2.11. One server acts as proxy only, and the other one is the "real" imap server". The credentials for the proxy service are stored in a remote MYSQL database. There were no trouble with dovecot 1.1.16. But now, with the most recent version, we get frequent login failures. It seems dovecot reconnects too late to the MySQL database after a timeout, after sending the SQL query. Here's a piece of my log file: May 7 14:46:32 ttt dovecot: auth(default): new auth connection: pid=5136 May 7 14:46:42 ttt dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=imap^Isecured^Ilip=xxx.xxx.xxx.xxx^Irip=yyy.yyy.yyy.yyy^Ilport=sss^Irport=26480^Iresp=<hidden> May 7 14:46:42 ttt dovecot: auth-worker(default): sql(uid,yyy.yyy.yyy.yyy): query: SELECT NULL as password, destuser, host, 'zzz' as port, 'Y' as proxy, '0' as proxy_timeout, 'Y' as nopassword, 'Y' as nodelay from accounts where user ='uid'; May 7 14:47:42 ttt dovecot: auth(default): worker-server(uid,yyy.yyy.yyy.yyy): Aborted: Lookup timed out May 7 14:47:42 ttt dovecot: auth-worker(default): mysql: Connected to lll.lll.lll.lll (imapauth) May 7 14:47:44 ttt dovecot: auth(default): client out: FAIL^I1^Iuser=uid^Itemp May 7 14:47:49 ttt dovecot: imap-login: Disconnected (auth failed, 1 attempts): user=<uid>, method=PLAIN, rip=yyy.yyy.yyy.yyy, lip=xxx.xxx.xxx.xxx, TLS May 7 14:48:26 ttt dovecot: auth(default): new auth connection: pid=5159 May 7 14:48:47 ttt dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=imap^Isecured^Ilip=xxx.xxx.xxx.xxx^Irip=yyy.yyy.yyy.yyy^Ilport=sss^Irport=6243^Iresp=<hidden> May 7 14:48:47 ttt dovecot: auth-worker(default): sql(uid,yyy.yyy.yyy.yyy): query: SELECT NULL as password, destuser, host, 'zzz' as port, 'Y' as proxy, '0' as proxy_timeout, 'Y' as nopassword, 'Y' as nodelay from accounts where user ='uid'; May 7 14:48:47 ttt dovecot: auth(default): client out: OK^I1^Iuser=uid^Idestuser=luid^Ihost=mmm.mmm.mmm.mmm^Iport=zzz^Iproxy^Iproxy_timeout=0^Ipass=<hidden> May 7 14:48:47 ttt dovecot: imap-login: proxy(uid): started proxying to mmm.mmm.mmm.mmm:zzz/luid: user=<uid>, method=PLAIN, rip=yyy.yyy.yyy.yyy, lip=xxx.xxx.xxx.xxx, TLS May 7 14:48:48 ttt dovecot: imap-login: proxy(uid): disconnecting yyy.yyy.yyy.yyy As you can see, the second login attempt is always successful.

[Dovecot] authentification failure: double quotes in password
by Martin Ott 07 Jun '10

07 Jun '10

we use Passdb LDAP with authentication binds against an Active Directory Server. The problem with one of our users seems to be the usage of double quotes in his password, as the windows-login works: /var/log/dovecot-info.log auth(default): Info: ldap(testuser 77.22.xx.xxx): invalid credentials (given password: xxxxx"xxxxxxx) Which chars in passwords does the dovecot auth process not like? Is there something similar to auth_username_chars for passwords? thanks, martin

[Dovecot] DOES NOT PERTAIN TO DOVECOT: Does anyone use postfix for some help?
by Jerrale Gayle 05 Jun '10

05 Jun '10

When mail is sent from the mail server, it shows up as originating from the MAIN ip address of the server, 173.50.101.11, when the mail server is bound to 173.50.101.12. I have already set smtp_bind_address: 173.50.101.12 in main.cf and 173.50.101.12:smtp inet - - smtpd in master.cf. This prevents smtp connects TO any other ip but 173.50.101.12 BUT mail STILL shows up originating from eth1, where 173.50.101.12 is eth1:2 I think this is *nix related and most here, on dovecot mailing list, could provide help.

[Dovecot] Managesieve connection hangs with TLS
by Joel James Adamson 04 Jun '10

04 Jun '10

Hello, I've got dovecot 1.2.11 running on Fedora 12 (x86_64) with the managesieve protocol and sieve plugins enabled, with deliver handling local delivery. I've set disable_plaintext_auth = yes ssl = yes ssl_cert_file = /etc/pki/dovecot/certs/dovecot.pem ssl_key_file = /etc/pki/dovecot/private/dovecot.pem mail_debug = yes protocol managesieve { listen = *:2000 login_executable = /usr/libexec/dovecot/managesieve-login mail_executable = /usr/libexec/dovecot/managesieve } and generated local SSL certificates; everything is going fine on the IMAP end of things (clients ask if I trust the certificate the first time, etc). I've open the appropriate ports, etc. No problems with mail delivery. However, I can't connect to the managesieve daemon. I've tried the Emacs client[1], and it just hangs. I tried manual login to port 2000 and here's what happened: joel@chondestes: /etc/mail > gnutls-cli --starttls -p 2000 localhost Resolving 'localhost'... Connecting to '127.0.0.1:2000'... - Simple Client Mode: "IMPLEMENTATION" "dovecot" "SIEVE" "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" "SASL" "PLAIN" "STARTTLS" "NOTIFY" "mailto" "VERSION" "1.0" OK "Dovecot ready." *** Starting TLS handshake C-c C-c That last line is me hanging up in Emacs' shell buffer because nothing was happening. Sorry to sound like such a newbie, but what do I need on the client end to complete the TLS transaction? What else do I need to set up to get managesieve to connect?

[Dovecot] dsync panic in dsync-worker-local.c - 2.0.beta4
by Frode Nordahl 04 Jun '10

04 Jun '10

Hello, While testing mailbox conversion I encountered a Panic in dsync on a few users mailboxes. Running dovecot 2.0.beta4 on RedHat Enterprise Linux 5 (x86_64).

[Dovecot] 'doveadm who' enhancement request
by Brad Davidson 04 Jun '10

04 Jun '10

When Dovecot is in proxy mode, the client sends along the original connection endpoints in an ID command. Is there any chance 'doveadm who' could use this to display the original connection source? As it currently stands, all I see is a bunch of connections from the proxy. Thanks! --- Brandon 'Brad' Davidson Virtualization Systems Administrator University of Oregon Information Services (541) 346-8098 brandond(a)uoregon.edu

[Dovecot] Auto forward virtual users mail using Sieve
by Julian Baker 04 Jun '10

04 Jun '10

Hi All I'm trying to configure Dovecot to automatically forward mail to another account without the virtual user having to log-in first to Roundcube web mail. These are virtual users with no log-in to the server only Roundcube's web interface The situation is that I have two domains only who want to receive email at their domains, get a forwarded copy at their hotmail account, then log-in to Roundcube to reply. A Sieve script running in Dovecot seems the way to go, but the finer points of configuration have failed me. I got as far as 1) /etc/dovecot/dovecot.conf Adding: protocol lda { mail_plugins = cmusieve mail_plugin_dir = /usr/lib/dovecot/modules/lda } 2) /var/vmail/___domain___/___user___/.dovecot.sieve Created the .dovecot.sieve file in the domain/user directory and added: require ["fileinto ","reject","vacation","imapflags","relational","regex","notify"]; # Resend a copy of the message to another address # if true { redirect "julian(a)flatearth.co.uk"; } Which doesn't seem to have broken anything. Or worked. I'm assuming that as /var/vmail/___domain___/___user___/ is their virtual user home/mail spool the '.dovecot.sieve' file will get picked up. It seems that Dovecot isn't configured to use send via Deliver ? My conf is pasted before (Exim handles regular domain email forwarding mail for a bunch of virtual domains to pop accounts.)

[Dovecot] auth socket goes away on reload
by David Jonas 03 Jun '10

03 Jun '10

We're using the SQLite backend for authentication of Postfix SASL. When the db is replaced we HUP dovecot to close and reopen its connection. During this time it appears the socket file is removed and Postfix rejects the authentication attempt. From the logs: Jun 3 00:23:02 xxx dovecot: dovecot: SIGHUP received - reloading configuration Jun 3 00:23:02 xxx postfix/smtpd[14746]: warning: SASL: Connect to private/auth failed: Connection refused Jun 3 00:23:02 xxx postfix/smtpd[14746]: warning: unknown[dd.dd.dd.dd]: SASL LOGIN authentication failed: Jun 3 00:23:02 xxx postfix/smtpd[14746]: NOQUEUE: reject: RCPT from unknown[dd.dd.dd.dd]: 554 5.7.1 <user(a)example.com>: Relay access denied; from=<user2(a)example.com> to=<user(a)example.com> proto=ESMTP helo=<localhost.localdomain> Jun 3 00:23:02 xxx postfix/smtpd[14930]: warning: unknown[dd.dd.dd.dd]: SASL LOGIN authentication failed: Connection lost to authentication server Jun 3 00:23:02 xxx postfix/smtpd[14930]: lost connection after AUTH from unknown[dd.dd.dd.dd] Is there an obvious way around this? I know I could somehow merge the changes into the running sqlite db but that undermines the simplicity of the design I have. Maybe a patch to reopen the db if it's replaced? Or perhaps I should just switch to a different db format -- that's probably the quickest/easiest solution. Any other ideas? There are about 20k entries to deal with. Thanks, David

Hi, i think ive asked it before perhaps this feature can be included in dovecot2 couldnt get it run with dovecot 1.2.x if i use the postfixadmin superuser,domainadmin,domainuser layout so there are domainadmins defined in a sql table it would be a nice feature to break it down to be master only at there related domains via sql lookup at recent i think there is only the chance to give master rights to all adresses for users defined as masters -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] Dovecot aspects of fighting spam
by Phil Howard 02 Jun '10

02 Jun '10

I see no documents in the Dovecot documents wiki on how Dovecot features can be used in the fight against spam. One hit came up in a search, and it was about how to fight spam in the MoinMoin Wiki itself (e.g. TextCHAs and such). I already asked in another thread about removing message files at the search from a designated "learn-spam" folder. My next question would be how to automatically place detected spam into a specific folder for the user to access or ignore as they deem fit. That would seem to me to be something for the deliver command and its -m option. But this might be more of a Dovecot and MTA coordination issue, too (e.g. how to get the spam detection done in the MTA ... Postfix in my case ... to become a label of some sort that ends deciding the folder. The -m option might be harder to get it dynamically set since it would be hard coded in master.cf for Postfix (so a variable has to be able to direct it to INBOX in this case). But maybe the "standard" way of doing this is to shim another program between the MTA (Postfix for me) and the LDA (Dovecot deliver) to dynamically add the -m option on the fly? Lacking any other clever solution, this seems to me to be the way I could make it work. Maybe there is a special header deliver could detect, such as "X-Spam: yes"? A wiki document on how Dovecot helps (or how to help Dovecot) in the fight against spam, I think, would be helpful.

Then, out of nowhere, we started getting this error: Apr 21 19:15:17 IMAP(xx(a)xxx.com): Fatal: block_alloc(1073741824): Out of memory Apr 21 19:15:17 IMAP(xx(a)xxx.com): Error: Raw backtrace: imap [0x49e5e0] -> imap [0x49e643] -> imap [0x49dba1] -> imap [0x4a7f6d] -> imap [0x4a7f98] -> imap [0x4a8028] -> imap [0x49bf6f] -> imap(buffer_write+0xe4) [0x49c334] -> imap(mail_cache_lookup_headers+0x146) [0x46dcf6] -> imap [0x458162] -> imap(index_mail_get_first_header+0x45) [0x458685] -> imap [0x45fe44] -> imap [0x460008] -> imap [0x4796d1] -> imap(hash2_lookup+0x64) [0x4a1c94] -> imap(mail_index_strmap_view_sync_add+0x85) [0x47ab05] -> imap(mail_thread_init+0x2a5) [0x4602f5] -> imap(cmd_thread+0x161) [0x41f931] -> imap(cmd_uid+0x78) [0x41fb38] -> imap [0x42079c] -> imap [0x420852] -> imap(client_handle_input+0x3f) [0x42098f] -> imap(client_input+0x5f) [0x4214df] -> imap(io_loop_handler_run+0xf8) [0x4a63a8] -> imap(io_loop_run+0x1d) [0x4a54ed] -> imap(main+0x620) [0x428db0] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x3f75e1d8a4] -> imap [0x419969] Apr 21 19:15:17 dovecot: Error: child 25918 (imap) returned error 83 (Out of memory - see mail_process_size setting) The folder (which is shared) has about 8 thousand emails in it.

[Dovecot] configuring sendmail to work with dovecot+LDAP
by Douglas Maus 02 Jun '10

02 Jun '10

I would like to setup dovecot (1.1.20) with LDAP virtual users, but I don't seem to understand how to get my sendmail to accept mail for the virtual users. (I am rather new to this, so I may have some misunderstandings) I have followed - wiki.dovecot.org/HowTo/DovecotOpenLdap (OpenLDAP 2.3.43) and I think I have IMAP working for virtual users. I can connect to port 143, enter a username and password and it works. Now I surmise I need to configure my SMTP server to accept mail for these LDAP virtual users, and deliver it appropriately. (The above HowTo doesn't address this step, from what I can tell) I read - wiki.dovecot.org/LDA and wiki.dovecot.org/LDA/Sendmail (I'm using OpenBSD 4.7, which uses sendmail for MTA / SMTP server, sendmail version 8.14.3) For sendmail.cf, I made the changes in my sendmail.mc file to include the dovecot mailer (calling /usr/local/libexec/dovecot/deliver), and compiled with m4 and installed the new sendmail.cf For dovecot.conf, I edited the portions (abbreviated): protocol lda { auth_socket_path = /var/run/dovecot/auth-master } and auth default { socket listen { master {path = /var/run/dovecot/auth-master }}} When I try to test this, (telnet www.example.org 25) If I try: MAIL TO:jdoe@www.example.org I get "User unknown" I see that if I try: MAIL TO:jdoe@example.org I get "Relaying denied" Either way it doesn't get delivered. Thank you for any help. And if anyone knows a good basic tutorial for dovecot+LDAP+sendmail I would really appreciate it. dovecot -n (de-identified, and yes I know SSL is disabled, after it all works I'll fix it) ---------- # 1.1.20: /etc/dovecot.conf Warning: fd limit 128 is lower than what Dovecot can use under full load (more than 640).

[Dovecot] Migration - Dovecot to Dovecot
by Greg Pearson 02 Jun '10

02 Jun '10

Hi, I am using Dovecot with mbox format, and I am interested to move to Maildir. I have run the modified script (mb2md) but it seems UIDs are not preserved. I don't know how to verify this, but my client seems to be downloading all messages again. Can someone help?

[Dovecot] recipient_delimiter
by Phil Howard 02 Jun '10

02 Jun '10

I have recipient_delimiter = + in main.cf (Postfix). But deliveries to dovecot/deliver are still being rejected. It appears that the full email is still in the envelope (e.g. phil+howard(a)example.com which I want to be delivered to phil(a)example.com) Is that how it's supposed to work and Dovecot just doesn't support this?

[Dovecot] Intermittent timeout issues
by Del Stoliker 01 Jun '10

01 Jun '10

Greetings list! We've been experiencing an intermittent issue in which none users are able to log into the mail server for about 10 to 20 minutes. This issue first appeared on our CentOS 4 box running dovecot 1.2.11 after upgrading from the stock version 0.99. The issue persists after migrating our users to a CentOS 5 server - also running version dovecot 1.2.11 but now in the 64-bit flavor. Our users authenticate against LDAP via PAM in case that might be relevant. I've yet to find anything "of interest" in the logs covering the outages. But here is what I've noticed: * Users on our internal network are still able to authenticate and login. * Users from the outside are "Disconnected for inactivity" * Immediately after the restart, external users were able to log in again. It almost sounds like the firewall is blocking external access except that: * The version of dovecot was the thing that changed * Everything starts working again after a dovecot restart If anyone could provide some insight, I'd sure appreciate it.

[Dovecot] purge maildir folder after sa-learn
by Florian Effenberger 01 Jun '10

01 Jun '10

Hello, I am looking for a command-line utility to automatically purge one Maildir folder. I want to periodically run sa-learn from cron, and after the spam learning folder has been added to the Bayes database, its contents should be deleted. I've searched a bit, but only found a few old utilities or some telnet+expect scripts, which both didn't look too reliable. Is there any command-line utility to delete all contents of a Maildir folder, or is there any other solution? Thanks, Florian

Hello Dovecot admins. I've started writing manual pages for Dovecot v2.0. I'm sure they are not perfect yet. I'd like to ask you all to read the manual pages. It would be nice to get some ideas/suggestions/improvements. So that that the Dovecot v2.0.0 release could be distributed with /fine manuals/. The manual pages are available at: http://wiki2.dovecot.org/ManPages This is also the intended place for 'discussions' about the man pages.

[Dovecot] dovecot-2.0-pigeonhole/ManageSieve: wrong service name
by Pascal Volk 31 May '10

31 May '10

Hi Stephan, ManageSieve uses the wrong™ service name for the authdb lookup. With dovecot-1.2-managesieve the service name was changed from 'managesieve' to 'sieve'. So I altered my table layout in order to make the query "SELECT userid AS "user", password FROM dovecotpassword('%Ln', '%Ld') WHERE %Ls" work again. When I try to login on the sieve port 4190/tcp, I find this in my dovecot.log: auth: Error: pgsql: Query failed, retrying: ERROR: column "managesieve" does not exist auth: Error: LINE 1: ...", password FROM dovecotpassword('user', 'example.org') WHERE managesiev...

[Dovecot] Permanent flags not announced and public mailbox with per-user index
by Julien Danjou 31 May '10

31 May '10

Hi, I've a set of public mailboxes that all users can access. The index is stored per user, so each user can mark the message as read for themselves. This is with dovecot 1.2.10. However, when selecting the mailbox, system flags are not announced as permanent but only as session flags: 3619 SELECT "public.Admin" * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 324 EXISTS * 0 RECENT * OK [UNSEEN 171] First unseen. * OK [UIDVALIDITY 1254326934] UIDs valid * OK [UIDNEXT 1102] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest 3445 OK [READ-ONLY] Select completed. I think (reading the RFC, but I bet you know it better than me) that FLAGS should also been set in PERMANENTFLAGS since they can be permanent. The relevant code seems to be in commands-util.c (dovecot 1.2.11): void client_send_mailbox_flags(struct client *client, bool selecting) { […] if (mailbox_is_readonly(client->mailbox)) { client_send_line(client, "* OK [PERMANENTFLAGS ()] " "Read-only mailbox."); } else { […] } } Even if it's true that the Maildir is read-only, it's still possible to store \Seen permanently. Am I getting things wrong, or is this a bug? If I'm correct, a simple fix MAY be not to send the PERMANENTFLAGS at all since the RFC says: OK [PERMANENTFLAGS (<list of flags>)] A list of message flags that the client can change permanently. If this is missing, the client should assume that all flags can be changed permanently. Thanks, -- Julien Danjou // ᐰ <julien(a)danjou.info> http://julien.danjou.info

As this is a fresh installation of dovecot I do not know if older versions work better.

[Dovecot] 1.2.11, mbox, new mail
by Stan Hoeppner 31 May '10

31 May '10

With 1.2.11 and mbox storage, the delay time in pulling new mail headers to the client from imap folders seems to be directly proportional to mailbox size, regardless of the number of new messages. At present, if the mailbox is large, pulling new headers is rather painfully slow. Is this expected behavior? Especially given that the client already has all the "old" mails in the folder cached, and thus wouldn't be asking for them? Is there a setting(s) I can change to optimize/fix this? -- Stan

[Dovecot] strange sieve situation
by Andy Dills 31 May '10

31 May '10

Hi there, I've been working on rolling out the "deliver" service so we can implement sieve. Dovecot 1.2.11, Postfix 2.6.6, FreeBSD 8, installed by ports. Clustered environment, NFS backend. Everything is working great for the most part, I'm using it to sort a copy of my personal email on a test server. However, I noticed two emails were not properly sorted. I had added a rule (using Ingo, nice little piece of software) to redirect the nightly FreeBSD security output emails into a folder "servers". However, nothing had triggered that rule, and the "Maildir/.servers" directory had not yet been created. Then, three of the "security outputs" came in at one time: May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: msgid=<20100529070108.F2F0B7F5D4(a)mail-out04.xecu.net>: failed to store into mailbox 'servers': Mailbox already exists May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: msgid=<20100529070109.D8F5E159913(a)mail-out01.xecu.net>: failed to store into mailbox 'servers': Mailbox already exists May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: msgid=<20100529070109.D8F5E159913(a)mail-out01.xecu.net>: stored mail into mailbox 'INBOX' May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: execution of script /mail/var/mail2/xecunet/andytest.xecu.net//.dovecot.sieve failed, but implicit keep was successful May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: msgid=<20100529070110.17A781B53B9(a)mail-out02.xecu.net>: stored mail into mailbox 'servers' May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: msgid=<20100529070108.F2F0B7F5D4(a)mail-out04.xecu.net>: stored mail into mailbox 'INBOX' May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: execution of script /mail/var/mail2/xecunet/andytest.xecu.net//.dovecot.sieve failed, but implicit keep was successful That's the order they appeared in my logfile. I'm assuming they were all sent to deliver at the same time, they all thought they needed to make the directory, the one with msgid 20100529070110.17A781B53B9(a)mail-out02.xecu.net was able to make the directory and get delivered, whereas the other two freaked out because they couldn't make the directory they thought needed to be made, and just sent the mail to the inbox. That's a reasonable approach, although I wonder if deliver/sieve could be (or perhaps "has been in 2.0") adjusted to more intelligently handle that edge case. Also, I'm wondering about "dovecot_destination_recipient_limit = 1". I have that set in my main.cf, but I'm not 100% positive it's taking effect. # grep dovecot /usr/local/etc/postfix/main.cf dovecot_destination_recipient_limit = 1 virtual_transport = dovecot # grep dovecot /usr/local/etc/postfix/master.cf dovecot unix - n n - - pipe flags=DRhu user=mailman argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient} # postconf | grep dovecot smtpd_sasl_type = dovecot virtual_transport = dovecot # postconf | grep destination_recipient_limit default_destination_recipient_limit = 50 lmtp_destination_recipient_limit = $default_destination_recipient_limit local_destination_recipient_limit = 1 relay_destination_recipient_limit = $default_destination_recipient_limit smtp_destination_recipient_limit = $default_destination_recipient_limit virtual_destination_recipient_limit = $default_destination_recipient_limit Is "dovecot_destination_recipient_limit" being converted into local_ ?

[Dovecot] Unresolved client rejection
by Greg Pearson 31 May '10

31 May '10

Hi, would it be possible to prevent users who try to login from an unresolved IP from connecting to Dovecot IMAP? I have a suspicion that it should be done via the authentication module (ie PAM) but I am not sure (if this is the case could someone recommend a good resource or even a solution). For example sendmail has a relevant macro to achieve this, I was wondering if Dovecot can have similar behavior. Thanks

[Dovecot] imap folder aliases for different mail clients naming convention
by Robert Schetterer 31 May '10

31 May '10

Hi, sorry if this was asked before and/or if there is allready a solution different imap mail clients, have different imap folder naming conventions typical by sent , trash, spam i normally use thunderbird conventions, as its working on all major plattforms and configure hord/imp , squirrelmail to use it like thunderbird does, additional i use autocreate with this folders it would be nice to alias other mail clients naming conventions to TB folder naming conventions without poke around with i.e symlinks etc, i guess there might be some solution with namespaces but i hope i could be done more easy eventually with a alias plugin etc? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

( dovecot2/srv/lmtp/commands.c ~line 695 ) has somebody experiences while delivering huge ammount of mail via dovecot2 lmtp service? - is it faster/slower/comaparable with deliver? - it's hard to believe, that nobody realy misses the return-path header Thanks, Andreas -- Andreas Schulze Internetdienste | P532 DATEV eG 90329 Nürnberg | Telefon +49 911 319-0 | Telefax +49 911 319-3196 E-Mail info @datev.de | Internet www.datev.de Sitz: 90429 Nürnberg, Paumgartnerstr. 6-14 | Registergericht Nürnberg, GenReg Nr.70 Vorstand Prof. Dieter Kempf (Vorsitzender) Dipl.-Kfm.

[Dovecot] Dovecot 1.2 - Quotas - Ignoring Trash folder
by Shayne Jellesma 30 May '10

30 May '10

Hello guys, Firstly I would like to state that I am fairly new to Dovecot. I have played around with it in the past here and there but mainly with debian packages. I have compiled this version of Dovecot from source, so please go easy with me. Ok now down to my questions: I am having trouble getting Dovecot to 'ignore' the Trash folder when summing up the used quota for a user. I am running Dovecot 1.2.11 (with LDA), Postfix 2.5.5, and Postfixadmin 2.3. I am able to send and receive emails fine. Roundcube displays the quota used but this quota also counts what is in the users Trash can. Postfix is configured to hand over delivering of the mail to Dovecot. I have tried different methods from the documentation on ignoring the Trash folder, but have not come up with anything that has worked yet. If someone could point me in the right direction, that would be great. I apologise now if I have not included all required information, I did read the mailing list guidelines and believe I have follow all required steps. charged:/usr/local/etc# dovecot --version 1.2.11 charged:/usr/local/etc# charged:/usr/local/etc# dovecot -n # 1.2.11: /usr/local/etc/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.4 ext3 base_dir: /var/run/dovecot/ log_path: /var/log/dovecot12.log info_log_path: /var/log/dovecot12.log protocols: imap imaps pop3 pop3s listen: 118.127.29.214 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login first_valid_uid: 5000 last_valid_uid: 5000 first_valid_gid: 5000 last_valid_gid: 5000 mail_privileged_group: vmail mail_uid: 5000 mail_gid: 5000 mail_location: maildir:/var/vmail/%d/%n/Maildir mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 namespace: type: private separator: . inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)ignitioncarclub.com mail_plugins: quota mail_plugin_dir: /usr/local/lib/dovecot/lda quota_full_tempfail: no auth_socket_path: /var/run/dovecot/auth-master auth default: mechanisms: plain login passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail plugin: quota: maildir:ignore=Trash trash: /usr/local/etc/dovecot-trash.conf charged:/usr/local/etc# charged:/usr/local/etc# grep -v '^ *$#.*$\?$' dovecot-sql.conf driver = mysql connect = host=localhost dbname=xxx user=mailuser password=xxx default_pass_scheme = MD5-CRYPT user_query = SELECT maildir, 5000 AS uid, 5000 AS gid, CONCAT('*:storage=', quota, 'B') AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' password_query = SELECT username as user, password, '/var/vmail/%d/%n' as userdb_home, 'maildir:/var/vmail/%d/%n' as userdb_mail, 5000 as userdb_uid, 5000 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' charged:/usr/local/etc# charged:/usr/local/etc# dpkg -l | grep postfix ii postfix 2.5.5-1.1 High-performance mail transport agent ii postfix-mysql 2.5.5-1.1 MySQL map support for Postfix charged:/usr/local/etc# Regards, Shayne Jellesma Network Administrator / ICT Support St Martins Lutheran College Web: <http://www.stmartins.sa.edu.au> http://www.stmartins.sa.edu.au Phone: (08) 87 251 430 Skype: shayne.jellesma.smlc

[Dovecot] Problems with Outlook clients after a migration
by Joseba Torre 28 May '10

28 May '10

Hi, I'm doing the final tests before I migrate my 10000 users from RHEL 4 + dovecot 1.1.20 to RHEL5 + dovecot 1.2.11, and I'm having some serious problems with outlook 2007 clients disconnecting very often. In dovecot's log I see lot of connects and disconnects from these clients (as oposed to my kmail, that just connects once when I come in and disconnects when I shut it off). After unchecking the "chek every X minutes" thing in outlook I get fewer of those -while functionality remains-, but the main problem still persists: every now and then (more or less 30 mins), the client disconnects, and sometimes the client goes offline. This didn't happen with my previous setup. I use the outlook-idle workaround, but it doesn't seem to make any difference. Any ideas?

[Dovecot] Cannot Access Inbox
by robertober 27 May '10

27 May '10

Hello Folks, Yesterday while messing around with procmail for SpamAssassin I had my IMAP client open and it lost it's ability to see my Inbox except for two messages. I tried another IMAP client and no success. I can see all other directories such as sent and the ones I have made. The mbox file is there and catable/grepable. I even made a new one. I can read a test account Inbox from the same server with my usual client. Also my small number of other users appear to be using pop3 as normal. Tried so far: * Multiple clients including pop3. * Removed spamd and procmail stuff. * Various permissions. * New mbox. * Restart everything, although I am not sure I rebooted the server last night. * Searched for lock files that may need to be deleted. * Googled. Server setup: * Mandriva Linux 2009.1 * Dovecot 1.1.13 * Postfix 2.5.6 The mailbox in question is my business and some personal email so I would greatly appreciate any help towards fixing this issue. I am self-employed and largely out of business without my email. Thanks, Robert A. Ober

[Dovecot] symlinking maildirs
by Phil Howard 27 May '10

27 May '10

I have some emails that I think are in the Postfix delivery queue going to Dovecot, but didn't get mapped to their alias (because I didn't have all the alias entries in when they were queued). I'm wondering if this trick would work. I have the mail being delivered to /home/mail/%Ld/%Ln/mail and am wondering if I could make a symlink at /home/mail/example.com/foo -> bar and add a dummy password for foo(a)example.com and have that mail trying to go to foo(a)example.com really go to bar@example and make a successful delivery (it is soft bouncing right now).

[Dovecot] Dovecot access imap folder via POP3
by Vincze Janos Istvan 27 May '10

27 May '10

Dear All, I use postfix and dovecot (1.1.11) combo with maildir format. I would have a question about dovecot config. Can I confiugre dovecot to download mails from IMAP folders via POP3? Now, mails can be downloaded only from .INBOX. My dovecot.conf file: .... mail_location = maildir:/home/vmail/%d/%n/Maildir namespace private { separator = . prefix = INBOX. #location = mail_location = maildir:/home/vmail/%d/%n/Maildir inbox = yes #hidden = yes } mail_privileged_group = mail .... Thank you for any help, Janos, Vincze

[Dovecot] Overly long email of miscellaneous Dovecot migration questions
by Mark Moseley 27 May '10

27 May '10

Hello to the list! I've been asked to spec out the feasibility and, if feasible, plan a migration from Courier to Dovecot for both POP3 and IMAP for about 4 million mailboxes. I've been trying to absorb all the dovecot-related info I could over the past couple of weeks from the docs and from the list and I'm sure that I've muddled at least some of it, so apologies in advance if I make grossly incorrect assumptions. BTW, sorry for the giant email but I've got a bunch of questions. This is the sort of overly wordy email that makes my eyes glaze over in mailing lists. But I've got things configured to where (I think) everything will 'just work' if we migrate (barring running POP3 mailbox conversions), so I'm not looking for configuration help, just gotchas and assumption-checking mostly. Me breaking 4 million mailboxes isn't really a good move for my job security ;) * Since Dovecot 2.0 seems like it's just around the corner, that's all I've been testing, and indeed all I've even looked at. * This is a pretty fantastic piece of software. I love the neat little details that make admins' lives easier, e.g. how easy it is to use multiple SSL certs in the same server. That made me smile. I hadn't looked at dovecot in a number of years, so I was really impressed at the full feature set. It's been a while since I've played with a new server application that I've enjoyed this much. * Background: All of our mail is stored on NFS and will be for the foreseeable future, all in maildir format. Courier POP3/IMAP runs on load balanced Linux servers, so clients will be hitting multiple servers, though stickiness based on client IP address is currently done. Webmail as well is done on top of a local Courier IMAP server accessing the same NFS servers but on an entirely different pool of servers. All authentication is done against SQL. Courier has been very, very good to us over the past 9 years, but our NFS servers (12 Netapps) are unfortunately being beaten to death. We've got lots of users with thousands of emails in their inbox (i.e. in ./Maildir/cur/ alone) and I've seen plenty of mailboxes with 10's of thousands in their inbox and I've even seen some really scary ones approaching 100k emails just in cur/. Thanks to an endless cycle of industry raising mailbox limits, we actually have to support this (though not so much the 100k message ones, at least). * Our #1 main motivation for looking Dovecot is relief for our currently overtaxed NFS servers, mostly in the form of the index files. Benchmarking dovecot looks great, even with the index files in the maildir. I know the cool thing to do would be to move the index files to a separate NFS server running entirely on SSDs for the fastest accesses possible. Building a separate index NFS cluster obviously adds complexity and performance with the index files in the maildir seems pretty great already. But I also know that real life often makes assumptions made during benchmarks look very foolish. My inclination is to try things out with the indexes in the maildir directory (and then start looking at moving to a dedicated NFS server for the indexes in a subsequent phase) but I don't want to regret that choice later. Anybody with large-scale NFS maildir stores have any advice either way? * Exim: We currently deliver all of our mail via Exim on separate servers. Our POP3/IMAP servers only do POP3/IMAP and the Exim mail servers delivering to maildirs only do Exim. From what I've seen in the docs and various threads, from what I can gather, the best thing to do in that case would be to use Exim's built-in maildir handling, instead of using 'deliver'. That would be my preference anyway, but I wanted to make sure I didn't misinterpret things. * Any problems running Courier POP3 and Dovecot IMAP for a while, possibly Courier IMAP and Dovecot IMAP concurrently?: Since migrating POP mailboxes is going to be a mighty task, our gameplan would probably be to start migrating *just* IMAP services at first and likely on just a few servers at a time. Being load balanced, there are several scenarios where a user could theoretically access a mailbox on different servers and therefore end up hitting dovecot at one point in time and then later hitting courier or vice versa. Or they could use IMAP from one location and POP3 (during the span of time before we migrated our POP3 services) from another. I've not yet seen any side effects from switching mail servers like that (though I'm aware of what would happen if both dovecot and courier *POP3* were in service at the same time -- redownloaded mail, bleh). Has anyone seen otherwise? I'm not worried as much by the 0.1% of IMAP users who might be using advanced features but rather the other 99.9% who are using it pretty vanilla-ishly. * Union mailboxes: I'm pretty sure in a fairly recent thread that Timo said that something like a 'union' mailbox (at least with maildir) wasn't possible. I tried messing with multiple 'private' namespaces (i.e. a namespace called "ARCHIVE" with a "location" different than the INBOX location, ideally placed on slower but denser NFS servers) but even with 'hidden=no' and 'list=yes', only the main INBOX folders would show up, so I'm guessing that's not going to work. That would be a killer feature, to be able to serve an alternate namespace that would show up in a mail client's subscribable list that could be on slower storage than the main inbox (though I'm not sure a mail client can even handle multiple namespaces). * Any problems with keeping only quota limits in db and not current quota numbers? Our limits come out of a SQL table but the current counts just live in the maildir file. Trying to update quota counts in SQL for 4 million mailboxes is a non-starter for us at this point. >From what I've done, dovecot seems pretty happy to maintain the quota using the 'maildir' quota plugin but let it be overridden by the userdb lookup. So I think I'm fine on that count, but I'd love to hear from anyone knowing of extreme gotchas doing it that way. * Any problem with leaving the namespace in "Courier compatibility" mode? I.e. in namespace 'private', leaving "prefix = INBOX.". With 4 million mailboxes, FAQs all over the place, and support reps trained in a particular way of doing things in IMAP, it'd be hellish to try to change the prefix (I know I could leave the courier namespace around with 'hidden=yes' but retraining support staff is perhaps better left to phase #2). Do I lose anything besides tidiness by not changing it to "prefix =" as if I was deploying dovecot from scratch? Does it hurt performance in any significant way? Benchmarking doesn't look any different, so I'm guessing not. * One thing that threw me and might be good for a FAQ (unless it was just me misconfiguring things) was when I started playing with putting the index files in an alternate location. I was utterly perplexed why it'd create the directories for the indexes but they'd be empty. Based on their location and names when they're in the maildir, I was just looking for the same dovecot.index* files right in the alternate directory. It wasn't till I started strace'ing that I noticed that the index files were indeed getting created but in a subdirectory called .INBOX (and with me just doing 'ls'). * The courier-dovecot-migrate.pl does a fine job at converting our POP3 mailboxes. We'll definitely be doing a mass run of it across all of our mailboxes. But with this many mailboxes, there's no way to get around the time lag between the script getting run and new mail showing up. Which means that there'll be some number of new messages that will re-download in POP3 when the switchover to Dovecot POP3 is done. To keep from getting too many complaints from customers, I'm thinking that I might have to write a wrapper script to do something like compare the mtime of ./Maildir/new/ against dovecot-uidlist and overwrite if ./Maildir/new/ is newer or perhaps see if the mtime of courierpop3dsizelist is newer than dovecot-uidlist and only if that's the case execute the conversion script with --overwrite. Considering we get between 500-2000 POP3 logins/sec, running any script after a POP3 login terrifies me--even a 6 line bash script. Anybody have any opinions to share on that? With a pooled architecture, it's near impossible to only have some mailboxes hit Courier and some hit Dovecot and keep slowly incrementing. At best my available units of increments to migrate are a few thousand at a time and more realistically 10-20k at a time. If we're going to have to live with users complaining about a one-time redownload of just post-conversion mail, I'll need to get started convincing the higher-ups that that's life. A big thanks to anyone who even actually reads this entire tedious email and a tremendous thanks to anyone who actually replies to any of it!

[Dovecot] listescape und sieve
by Heiko Schlittermann 26 May '10

26 May '10

Hello, bug or feature? I'm using Dovecot 1.2.11. And because of a migration projekt I'm tempted to use the listescape plugin. If I understood well, it plugin { escape_char = "%" } should change the escape character to %. But it doesnt. Bug or feature? But more important: # sieve fileinto "a.b"; does not work as expected - the folder is visible as "a.b" in a normal imap client - because of the listescape plugin. # sieve fileinto "a\\2eb"; works. But the user won't understand this. Any ideas?
