Re: [Dovecot] Android ICS stock client and IMAP Capability issue.

Hi, Yes w/o prefix work as expected, try to add a prefix like courier does (eg. Inbox.) It will not work as expected. Due I'm upgrading an old installed server, I've to keep everything as much transparent I can... it includes IMAP folder and subscription. Looking at that I've encountered that issue, and analyzed for fix it (thank you open source), not everyone will want to use/use k9.. but you can be 100% sure the stock client is there. Due that Google act like BlackBerry, Microsoft,etc.. (hovewer they will not fix it soon, or really respect the rfc), it's much simple add Namespace on prelogin banner then wait or have to tell someone to install another client for that mailbox. I didn't know the history, but looking at change log seems that idle as been put back to prelogin client for some kind of compatibility with their service. Anyway, the most important reason that got me to subscribe the mailing list for write those emails, is share with the community that problem and provide a solution.. for someone in the future that have the same problem and will search on internet for a solution (like I've does.. before analyze it on my own). If the workaround will be added to the wiki or will be put in the source.. the important thing is that there is a solution simple and fast (two.. the source modify, and the configuration file) and someone can find it.. (Sarcastic) And if the mayans were right we can't wait for google to fix it :p Best Regards Sent from Galaxy Nexus Robert Schetterer <rs(a)sys4.de> ha scritto: >Am 07.11.2012 08:13, schrieb Massimiliano Cianelli: >> Hello, >> >> My phone: >> Android ics 4.1.2 on galaxy nexus. >> And yes, stock mean the default client that come with the os in IMAP mode. >> >> I already know about that configuration parameter, but it will display two time namespace in postlogin capabilities, and so I like much more to adjust the source code to fix the issue. >> >> Yes there is k9 but I didn't like it too much, I prefer the stock client and is much important to keep compatibility with stock client then user-installed client. >> >> About the issue on Google code, there is thr issue on google code... but Google is a lot slow in fixing those things. >> http://code.google.com/p/android/issues/detail?id=1811 >> >> In a few hour I'll update the issue noticing where is hidden the problem. >> >> Regards >> Sent from Galaxy Nexus > >Hi , i shortly tested this with android sdk jelly bean 4.1.1 and "my >setup" dovecot 2.1.10 with included orginal android mail app in imap mode, >,leaving IMAP prefix blank, everything works as expected, no double >shown inbox, namespace problems etc >so you might have to fit your namespace setup. >Also you might follow allready given advice from here. > >Anyway , i understand you using "stock client" >but you have to understand that the producers of mail clients >optimize their stuff fitting best in their own server structure >making money with it, therefor their motivation coding better imap code >is not very high, same case is for outlook and microsoft >however, i would say, fixing bugs is on the google site here, looks like >there is patch >at >http://code.google.com/p/android/issues/detail?id=1811 >and the issue seems long known > >i dont see any hard relation to dovecot in this case >meanwhile using k9mail seems the best way to workaround >there are lots of other bugs around android versions >over the years i dont expect google to fix them > > >> >> Robert Schetterer <rs(a)sys4.de> ha scritto: >> >>> Am 06.11.2012 07:08, schrieb Ben Morrow: >>>> At 6AM +0100 on 6/11/12 you (Massimiliano Cianelli) wrote: >>>>> Hi, >>>>> >>>>> My setup: >>>>> Dovecot 2 latest, installed to replace courrier IMAP, and off course >>>>> configured with the dot separator and all folder under INBOX.*. >>>>> >>>>> The problem: >>>>> My phone was driving me mad during the test, due that it will only >>>>> recognize Inbox. >>>>> >>>>> How found the solution: >>>>> I've started sniffing IMAP traffic on my server and ended up with one >>>>> difference: >>>>> On courier it ask for namespace, on dovecot it won't. >>>>> >>>>> I gives a better look, and noticed that courier show namespace >>>>> capability on prelogin banner, adding it too solved the problem. >>>>> >>>>> Reason: >>>>> Android ICS stock client seems do not honor the capability gived after >>>>> the login. >>>> >>>> See http://wiki2.dovecot.org/Upgrading/2.0?highlight=%28capability%29 ; >>>> you need to set imap_capability and/or get your client fixed. >>>> >>>> Ben >>>> >>> >>> Hi, first ,what is the exact meaning of >>> >>> "Android ICS stock client" >>> >>> do you mean default included email client in standard android in imap >>> mode, when yes, which version of Android , i like to test my own >>> however is there changelog/code etc at google for this behave? >>> >>> conf example >>> >>> # Override the IMAP CAPABILITY response.

Hello, i use dovecot with maildir. The maildir-folder looks like this: vmail/mail/user1/cur vmail/mail/user1/.Sent vmail/mail/user1/.optionalfolder Procmail should put some definded mails in the "optionalfolder" My uses configuration does not do this: ... DELIVERMAIL="/usr/lib/dovecot/dovecot-lda" IMAP="$DELIVERMAIL -e -d $LOGNAME -m INBOX" ZUSATZORDNER="$DELIVERMAIL -e -d $LOGNAME -m .optionalfolder" ... dovecot-lda puts the mails for the optionalfolder always in the .cur (INBOX). What´s the correct dovecot-lda parameter to put the mails in the optionalfolder? Thank you! Tony

[Dovecot] Auth USER lookup failed
by Angel L. Mateo 07 Nov '12

07 Nov '12

Hello, I'm running dovecot 2.1.9 and I'm trying to configure shared folders. So, as described at http://wiki2.dovecot.org/SharedMailboxes/Shared I have configured a namespace like this: namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = yes } In one user (user1) I have configured ACLs so another one (user2) has access to a folder. Now, I want to susbscribe user2 to this folder. The problem I have is that whenever I try to list folders for this user (running thunderbird client) I get a panic and an error in the dovecot server (I have attached the complete log). The error says: Nov 6 11:58:56 myotis30 dovecot: auth: Error: userdb(user1): client doesn't have lookup permissions for this user: userdb uid (113246) doesn't match peer uid (14585) (change userdb socket permissions) Nov 6 11:58:56 myotis30 dovecot: auth: Debug: master out: FAIL#0112 Nov 6 11:58:56 myotis30 dovecot: imap(user2): Error: user user1: Auth USER lookup failed Nov 6 11:58:56 myotis30 dovecot: imap(user2): Debug: auth input: Nov 6 11:58:56 myotis30 dovecot: imap(user2): Error: Couldn't create namespace 'shared/' for user user1: userdb didn't return a home directory, but plugin setting quota used it (%h): dict:User quota::file:%h/Maildir/dovecot.quota It seems that imap process running for user2 is trying to a user lookup that fails. So I have manually tried it root@myotis30:/etc/dovecot/conf.d# sudo -u user2 doveadm user user2 userdb: user2 home : <homeDirectory> uid : 14585 gid : 404 root@myotis30:/etc/dovecot/conf.d# sudo -u user2 doveadm user user1 doveadm(user2): Error: user user1: Auth USER lookup failed doveadm(user2): Error: userdb lookup failed for user1 I have checked the socket permissions, but they are 0666 (if I'm looking the right socket): root@myotis30:/etc/dovecot/conf.d# ls -l /var/run/dovecot/auth-userdb srwxrwxrwx 1 dovecot root 0 nov 6 11:43 /var/run/dovecot/auth-userdb In fact, I have tried to put all sockets with permissions 0666 and 0777, but the error persists.

[Dovecot] LDAP congestion
by Bernhard Schmidt 07 Nov '12

07 Nov '12

Hello, I've been asked to have a look at a misbehaving mail server of some colleagues today where almost all logins where failing or excessively delayed, while the LDAP database itself was pretty fast. They run Dovecot 1.2.11 (yes, I know, stoneage) against an LDAP server run by a 3rd party, auth_bind=yes (required). The problem is that this third party LDAP server delays bindResponse 3 seconds when the password is wrong. A user wanted to login every 2-3 seconds this morning with the wrong password, which effectively killed the system because the LDAP connection was mostly stalled waiting for the auth timeout. >From a previous discussion with Timo I know that bindRequests cannot be parallelized in LDAP, so the problem does not come completely unexpected. Other than removing the failure delay in the LDAP server, is there anything one can do? If there is any change in newer Dovecot versions about that please tell me so I can encourage them to upgrade, but I haven't seen anything in the changelog. Any way to get several LDAP workers/connections for passdb in parallel? Thanks, Bernhard

[Dovecot] "starting" dovecot

My system never issues the "dovecot start" command. I do, however, run /usr/local/libexec/dovecot/imap on port 9xxx. I talk to the server through port 9xxx and through the preauth tunnel. Is this arrangement OK? Are there some things that will only work if "dovecot" is invoked?

[Dovecot] Modifying mailbox GUIDs?
by Faheem Patel 07 Nov '12

07 Nov '12

Greetings all, I can view a mailbox's GUID like so: doveadm mailbox status -u guid However, how may I *modify* a mailbox GUID? Can this be done using doveadm or some other tool? If not, how may I go about modifying the dovecot.mailbox.log (where I assume GUID data is stored)? My specific use case has to do with me wanting to modify an existing mailbox's GUID so that its messages are mirrored into a folder of the same name using "dsync mirror". (As we know, dsync utilizes GUIDs to determine mailbox uniqueness) Thanks! -- - Faheem

Hello, I'm using 2.1.7 with seive and mysql quotas. We had an outage the other day where the database server where quotas are stored was not available for a short period of time. In dovecot land, the following types of errors occured in that scenario: Oct 26 22:19:01 grosbeak dovecot: lda(example(a)riseup.net): Error: Internal quota calculation error Oct 26 22:19:01 grosbeak dovecot: lda(example(a)riseup.net): Error: sieve: msgid=<20122132765181x.ABCCE457(a)example.com>: failed to store into mailbox 'Trash': Internal error occurred. Refer to server log for more information. [2012-10-26 22:19:01] Oct 26 22:19:01 grosbeak dovecot: lda(example(a)riseup.net): Error: sieve: script /maildir/e/example/.dovecot.sieve failed with unsuccessful implicit keep (user logfile /maildir/e/example/.dovecot.sieve.log may reveal additional details) I expect that there would be quota calculation errors as dovecot could not reach the database server, but what worried me was the 'failed to store into mailbox' message from sieve. The 'Trash' mailbox in this particular seive script is the correct location for the message to be filed into, but the worrisome message is the 'failed with unsuccessful implicit keep'. I looked through all the message-ids that reported this error and I found that the messages were properly delivered in the end, so this might be some issue interacting between sieve, dovecot and quota and just causing a scary message that can be ignored? thanks for any information you can provide, dovecot is great! micah --

[Dovecot] how to best import Evolution/Thunderbird mail into dovecot?
by Christoph Anton Mitterer 07 Nov '12

07 Nov '12

Hi. I'm migrating all my mail archive (some 60 GB) from Evolution (which is really a broken piece of software) into dovecot. Now I face the problem how to do this best... Evolution (which is still a old 2.32.x version) itself uses mbox files, in a special hierarchical structure to allow subfolders and that like. It also stores it's own status info in X-Evolution and X-Evolution-Source mail headers. Unfortunately,... much of the mail was earlier from a Thunderbird installation, which uses it's own status headers (X-Mozilla*) that were not recognised by Evolution. I have no idea which mbox subformat was always used throughout the different programs and versions... 1) Any way to check for that? To make things worse... Thunder(burden) seems to have used a modified From_ line syntax... "^From -<address> <date>$" Ideally I'd like migrate all mail into dovecot (for storage reasons again, mbox) retaining the different status flags (read, forwarded, etc.) and getting rid of the proprietary headers (of course only when they were. First thing I tried was to simply copy mail within Evolution (i.e. dragging&dropping it from the local folders to the IMAP folders from dovecot). - that preserves the status from Evolution, but doesn't restore that from Thunderbird - it clutters up the information of all From_ lines... "<address> <date>" becomes "<address of my default evolution account> <now>" - neither does it handle the special Thunderbird From_ lines - neither does it remove the Thunderbird or the X-Evolution-Source headers - if Evolution has already had corrupted index files (and this is extremely likely... as it happens even immediately during recreating all of them)... so I may loose mail So my idea was that I need a program that: - can parse all the different mbox formats (those that use the quoted ">From" style and those that use Conent-Length) - can differentiate message headers from body (so that I can drop the proprietary headers and replace them by what dovecot uses as headers) - must of course understand multiline message headers 2) Any idea for a tool like that? The meaning of the X-Evolution and X-Mozilla* headers are easy to find on the web.... so I can convert them. So I basically "just" need a tool that parses all kinds of mbox formats... allow me to drop/add headers... and spits out the rest unmodified. 3) dovecot uses some special headers like X-UID and X-IMAPD... will it create these on it's own, the first time it processes the new mbox file? I mean these headers won't be there after creation. 4) Should I drop out (during) conversion... any other mail headers.. that dovecot uses as it's own? Thanks, Chris.

Hello, My phone: Android ics 4.1.2 on galaxy nexus. And yes, stock mean the default client that come with the os in IMAP mode. I already know about that configuration parameter, but it will display two time namespace in postlogin capabilities, and so I like much more to adjust the source code to fix the issue. Yes there is k9 but I didn't like it too much, I prefer the stock client and is much important to keep compatibility with stock client then user-installed client.

[Dovecot] sieve
by Christian Rößner 06 Nov '12

06 Nov '12

Hi, is there a sieve option that can reject a mail directly without creating a new mail and sending that out? I know about reject "Reject message goes here"; but I am looking for a mechanism that can reject Mail. Postfix can use reject_unverified_recipient to connect to LMTP and ask if a mail would successfully be enqueued and will return the status gotten from the LMTP server if not. Chances are high that the mechanism would work, too, if Dovecot would know about the sieve rule, while getting a connection on LMTP. Does Dovecot know all rules at this point or is sieve handled after the mail has already been accepted?

[Dovecot] Android ICS stock client and IMAP Capability issue.
by Massimiliano Cianelli 06 Nov '12

06 Nov '12

Hi, My setup: Dovecot 2 latest, installed to replace courrier IMAP, and off course configured with the dot separator and all folder under INBOX.*. The problem: My phone was driving me mad during the test, due that it will only recognize Inbox. How found the solution: I've started sniffing IMAP traffic on my server and ended up with one difference: On courier it ask for namespace, on dovecot it won't. I gives a better look, and noticed that courier show namespace capability on prelogin banner, adding it too solved the problem. Reason: Android ICS stock client seems do not honor the capability gived after the login. Request: Maybe is possible to put namespace capability in prelogin banner for the next version? That will solve trouble with a setup like the mine and android stock email client. Thank you, Best regards Sent from Galaxy Nexus

[Dovecot] Quota
by Christian Rößner 05 Nov '12

05 Nov '12

Hi, is it possible to ask Dovecot for a users quota by talking to the Dovecot server over TCP? I know about doveadm quota -u <user>, but I would like to know, if I can query for that over a network connection (on the Postfix ML they suggested writing a policy service that checks quota. Postfix is not always on the same server as Dovecot is). Does the LMTP protocol give that information somehow? I am not so familiar with LMTP. Or some Unix-Socket to query that could also be configured as inet_listener?

Hi. Even new mails delivered by my MDA don't get the ,S= and ,W= fields set... (but when I "upload" a mail via IMAP to dovecot, they are set) Is there some place in dovecot where I need to enable this? Or would it be the MDA that has to calculate and set this already when placing a file in ./new? Thanks, Chris.

I don't know if Dovecot takes advantage of this in any way though. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] dovecot dimensioning

Hi All, first post here, nice to meet you :) I've been using dovecot + postfix + clamav + spamassassin for years but always with few users. Now i must build a server for 1500 users, they will use various email software (thunderbird, outlook, ..) the webmail (i'm not sure if squirrelmail or roundcube) and blackberry devices (with the BIS service). There will be around 1000 domains (virtual_domains) and postfix will read its users and domains from mysql. Let's say that they will send and receive around 5000 emails per hour (10K in total per hour). I was thinking to use karspersky server instead of clamav. I already have the hardware, it is a server with 4 physical cpu (Intel Xeon E5504 @ 2.00GHz) and 24 gb of ram, do you think it is enough ? Thanks for supporting, regards and have a nice day, Mike

[Dovecot] Pigeonhole 3.3 broken against Dovecot 2.1.10

I'm compiling as I normally do. The config line for Dovecot is: configure --with-ldap --with-ssl --with-bzlib --with-zlib --with-stemmer --with-lucene --with-ldap followed by make & make install Then a 'configure' for Pigeonhole, followed by make, yields: libtool: link: gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast

[Dovecot] Out of memory/Managesieve

Hello, I have here a problem with managesieve. With the login about webmail (roundcube) comes here in the log: --snip dovecot: managesieve-login: Fatal: pool_system_realloc(4294967296): Out of memory dovecot: managesieve-login: Fatal: master: service(managesieve-login): child 10157 returned error 83 (Out of memory (service managesieve-login { vsz_limit=1024 MB }, you may need to increase it)) --snap I've increased of 2048M and the same above. then with 4096 M happens the following --snip dovecot: managesieve-login: Panic: epoll_ctl(add, 61538840) failed: Bad file descriptor dovecot: managesieve-login: Fatal: master: service(managesieve-login): child 9777 killed with signal 6 (core dumps disabled) --snap How can one solve then this? Any ideas greatly appreciated. Thanks. -- Mit freundlichen Grüßen, with kind regards, Jim Knuth --------- Backup interessiert niemanden - Auf Restore kommt es an!

[Dovecot] IMAP proxy between Office 365 client/Sun Messaging Server
by John Dalbec 31 Oct '12

31 Oct '12

I would like to be able to migrate messages from existing end-user accounts on Sun Messaging Server to Office 365 using an administrator login and password. Unfortunately the migration tool for Office 365 doesn't support SASL AUTHENTICATE PLAIN login. The online documentation I've found suggests that I should be able to configure dovecot as an IMAP proxy and have it log in to Sun Messaging Server with AUTHENTICATE PLAIN and encode_base64("user\0admin\0adminpw") in response to a login from the Office 365 migration tool. I'd like to configure dovecot to run only the IMAP proxy if possible. I was thinking of setting all accounts to use the same (strong) password in the proxy. Would anyone be willing to share a sample configuration? Thanks, John Dalbec ellucian Luminis system administrator Youngstown State University

[Dovecot] Unable to get Managesieve working
by Cliff Dunn 31 Oct '12

31 Oct '12

I have Roundcube webmail (v. 0.8.2) running with the managesieve plugin (v. 5.1). I am able to create sieve rules without any problems in Roundcube, but incoming mail is not being processed with the rule I specify. I suspect there is something that isn't configured correctly in dovecot, but unfortunately I am unable to find a resolution online and my very limited knowledge of dovecot isn't allowing me to solve this problem on my own. I am including my dovecot config below. Please keep my knowledge level in mind when suggesting options and let me know if there is any other information I can provide to help troubleshoot the problem. Thanks for any assistance! # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.6 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps managesieve ssl_cert_file: /etc/ssl/certs/postfix.pem ssl_key_file: /etc/ssl/private/postfix.key ssl_cipher_list: ALL:!LOW:!SSLv2 login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login mail_privileged_group: mail mail_location: maildir:~/mail:LAYOUT=fs:INBOX=~/mail/ mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve auth default: mechanisms: plain login passdb: driver: pam passdb: driver: pam userdb: driver: passwd userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix plugin: sieve: ~/.dovecot.sieve sieve_dir: ~/mail/sieve

[Dovecot] Dovecot stops to work - anvil problem
by FABIO FERRARI 31 Oct '12

Hi all, we have a problem about anvil, it seems that when we have a high load the dovecot stops to work. Sometimes it is sufficient to make a dovecot reload, but sometimes we have to restart it. These are the lines related to anvil in the dovecot.log: [root@secchia ~]# grep anvil /var/log/dovecot.log | more Oct 26 11:13:55 anvil: Error: net_accept() failed: Too many open files Oct 26 11:14:32 imap-login: Error: net_connect_unix(anvil) failed: Resource temporarily unavailable Oct 26 11:14:32 imap-login: Fatal: Couldn't connect to anvil Oct 26 11:14:33 pop3-login: Error: net_connect_unix(anvil) failed: Resource temporarily unavailable Oct 26 11:14:33 pop3-login: Fatal: Couldn't connect to anvil [...] (many lines like these) Oct 26 12:01:10 pop3-login: Fatal: Couldn't connect to anvil Oct 26 12:01:18 auth: Error: read(anvil-auth-penalty) failed: Connection reset by peer Oct 26 12:01:18 auth: Error: read(anvil-auth-penalty) failed: Connection reset by peer Oct 26 12:01:18 auth: Error: net_connect_unix(anvil-auth-penalty) failed: Connection refused Oct 26 12:01:18 auth: Error: net_connect_unix(anvil-auth-penalty) failed: Connection refused Oct 26 12:01:18 auth: Error: read(anvil-auth-penalty) failed: Connection reset by peer Oct 26 12:01:18 auth: Error: net_connect_unix(anvil-auth-penalty) failed: Connection refused And this is the output of the doveconf -n: [root@secchia ~]# doveconf -n # 2.0.1: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-308.11.1.el5 x86_64 Red Hat Enterprise Linux Server release 5.8 (Tikanga) xfs auth_cache_size = 1024 auth_cache_ttl = 21600 s auth_debug = yes auth_debug_passwords = yes auth_master_user_separator = * auth_mechanisms = plain login auth_socket_path = /var/run/dovecot/auth-userdb auth_verbose = yes base_dir = /var/run/dovecot/ disable_plaintext_auth = no hostname = mail.unimore.it info_log_path = /var/log/dovecot.log lda_mailbox_autocreate = yes log_path = /var/log/dovecot.log mail_debug = yes mail_location = maildir:/cl/mail/vhosts/sms.unimo.it/%Ln/Maildir mail_plugins = $mail_plugins quota mailbox_idle_check_interval = 60 s mbox_write_locks = fcntl namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = /usr/local/etc/dovecot.masterusers driver = passwd-file master = yes } passdb { args = dovecot driver = pam } plugin { quota = maildir:User quota quota_exceeded_message = Quota exceeded (mailbox is full) quota_rule = *:storage=200MB quota_rule2 = *:messages=100000 quota_rule3 = INBOX.Trash:storage=+100M quota_warning = storage=90%% quota-warning 90 %u quota_warning2 = storage=85%% quota-warning 85 %u quota_warning3 = messages=95%% quota-warning 95 %u quota_warning4 = messages=80%% quota-warning 80 %u setting_name = quota } postmaster_address = postmaster(a)unimore.it quota_full_tempfail = yes service anvil { client_limit = 199999 process_limit = 199999 } service auth { client_limit = 14500 unix_listener auth-userdb { mode = 0600 user = vmail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 } process_limit = 5000 } service imap { process_limit = 5000 } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 } } service pop3 { process_limit = 1024 } service quota-warning { executable = script /usr/local/bin/quota-warning.sh unix_listener quota-warning { group = vmail user = vmail } user = dovecot } ssl_ca = </etc/pki/tls/certs/ca_unimore_tcs.pem ssl_cert = </etc/pki/tls/certs/cert-852-mail.unimore.it-cluster.pem ssl_key = </etc/pki/tls/certs/mailcluster.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } verbose_ssl = yes protocol lda { mail_plugins = $mail_plugins quota } protocol imap { mail_plugins = $mail_plugins imap_quota } protocol pop3 { mail_plugins = $mail_plugins quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } [root@secchia ~]# And these are the limit settings in the OS: * soft nofile 131072 * hard nofile 131072 Have someone had the same problem? thanks in advance Fabio Ferrari

[Dovecot] lmtp out of memory - raw backtrace
by Daniel Parthey 31 Oct '12

31 Oct '12

Hi, Our setup: - 4 hosts with director and mailbox instance - delivery via director lmtp into mailbox lmtp - mailbox format: mdbox - storage on NFS - OS: Linux 2.6.32-44-server x86_64 Ubuntu 10.04.4 LTS - Dovecot 2.1.10 - Pigeonhole 0.3.3 We're getting strange "out of memory" lmtp errors/backtrace with dovecot 2.1.10 accompanied by high load caused caused by a lot of lmtp deliveries to one user. First action would be to increase vsz_limit to a higher value, but I just want to make sure there is no bug - before blindly increasing this limit. I think it should not crash and corrupt mdbox, even if memory limit is reached: Oct 29 20:14:56 10.129.3.249 dovecot: lmtp(26698, user1(a)example.org) Fatal: pool_system_realloc(16777216): Out of

[Dovecot] POP3 Proxy : user format not accepted
by Christian Gregoire 30 Oct '12

30 Oct '12

Hello, I want to use Dovecot as a POP3 proxy (http://wiki.dovecot.org/HowTo/ImapProxy) All is working fine on my sample platform, except that I have plenty (several thousands) of users that login using local_part#domain, instead of local_part@domain, which is an old setting on my POP3 server. And in that case, Dovecot returns 'Authentication failed'. Here is my proxy table : mysql> select * from tbl_proxy; +--------------------+-------------+--------------------+ | user | host | destuser | +--------------------+-------------+--------------------+ | christian(a)mydom.fr | 10.10.100.1 | christian(a)mydom.fr | | christian#mydom.fr | 10.10.100.1 | christian(a)mydom.fr | +--------------------+-------------+--------------------+ If I login on the Dovecot proxy with the '@' version, everything is fine : root : ~> telnet 10.10.100.24 110 Trying 10.10.100.24... Connected to 10.10.100.24 (10.10.100.24). Escape character is '^]'. +OK Dovecot ready. user christian(a)mydom.fr +OK pass azerty42 +OK christian#mydom.fr has 3 messages (3561 octets) And MySQL logs show the query : 121030 12:55:28 3 Query SELECT NULL AS password, host, destuser, 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS proxy, 'Y' AS nopassword FROM tbl_proxy WHERE user = 'christian(a)mydom.fr' If I login on the Dovecot proxy with the '#' version, it fails : root : ~> telnet 10.10.100.24 110 Trying 10.10.100.24... Connected to 10.10.100.24 (10.10.100.24). Escape character is '^]'. +OK Dovecot ready. user christian#mydom.fr +OK pass azerty42 -ERR Authentication failed. And nothing shows up the the MySQL logs. If I login directly on the POP server with the same credentials, no problem : root : ~> telnet 10.10.100.1 110 Trying 10.10.100.1... Connected to 10.10.100.1 (10.10.100.1).

Authenticate yourself. user christian#mydom.fr +OK Password required for christian#mydom.fr pass azerty42 +OK christian#mydom.fr has 3 messages (3561 octets) Any idea ? Is the '#' not internally supported in the user login by Dovecot ? Thanks in advance. Christian

[Dovecot] Dovecot does not update acl_shared_dict file
by Chris Smith 30 Oct '12

30 Oct '12

Hi all, Firstly, thanks for all your effort with this software. Much appreciated. I am having a slight issues trying to enable reading of other users mailboxes. The docs are a little sparse for those that aren't mailadmin heros, I wonder if anyone could please help me see where I am going wrong. I would like to allow some users to list and read the mailboxes of others. E.g: When User1 logs in, they are presented with a list of their own folders, and those of User2, User3, etc to which they have (e.g. read/list) access I followed the instructions on the wiki (for Version 1.X)- there are two concepts here: 1. Grant some [e.g. list/read] access on a mailbox folder to a particular user 2. Enable the acl_shared_dict to allow dovecot to track (and display to IMAP clients) the folders to which they have access. This will take the form of a BDB file: /var/lib/dovecot/shared-mailboxes.db This file can only be updated by using the SETACL command. *This is where I have the problem*. The SETACL command does nothing. No matter how hard I try, I cannot get dovecot to update this file. The only indication I have that the file exists and is readable by dovecot is the disappearance from the logs of the line: No acl_shared_dict setting - shared mailbox listing is disabled So I can see that dovecot knows the file is there because it does not complain any more. The file is there (because I created it myself, although it is empty: size = 0), and in a moment of weakness I made sure it could be updated (this will be changed back!): ls -l /var/lib/dovecot/shared-mailboxes.db -rwxrwxrwx 1 dovecot dovecot 0 2012-10-30 12:27 /var/lib/dovecot/shared-mailboxes.db But if I try to update the ACL, absolutely nothing happens: [ > command ] [ < reply ] > telnet localhost 143 < * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=CRAM-MD5] Email server > a login [User2] [pass] < a OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH ACL RIGHTS=texk] Logged in > a SETACL Inbox [User 1] rl < a OK Setacl complete.

[Dovecot] Problem about SSL for Dovecot.
by sheng-wei.lim 30 Oct '12

[Dovecot] Save/restore IMAP session state
by Timo Sirainen 30 Oct '12

30 Oct '12

Some future Dovecot version will have "imap-idle" processes where IDLEing IMAP connections get moved, so the system wouldn't waste so much memory for all the IDLEing imap processes. A week ago I thought I'd see how easy it would be to implement this. I got a basic proof of concept working as a "X-STATE" command. Save the state: a x-state * STATE AQDLW45QdwAAAAMAAABuAQAAAAAAAFAcffYAPHnpFctbjlDbYQAAcEmzCwAA a OK State exported. Restore the state: b x-state AQDLW45QdwAAAAMAAABuAQAAAAAAAFAcffYAPHnpFctbjlDbYQAAcEmzCwAA b OK State imported. This could also be used to implement quick session state restoring for webmails (as suggested by Michael Slusarz). For getting the imap-idle process there would have to be code that: * triggers the session saving when process is IDLEing * figures out what filesystem paths the imap-idle should be looking at (i.e. paths to selected mailbox's dovecot.index.log file and maybe for e.g. maildir new/) * send the session state string, paths and imap connection fd to imap-idle process via UNIX socket * implement the actual imap-idle process * implement a way for imap-idle process to send back the state and connection fd to restore the imap process The patch is ugly and still missing many things. Anyway I thought I'd include it here just in case someone was really eager to continue implementing it. :) I'm not sure when I'll have time for it. A full patch would probably have to have some session_save()/session_restore() functions in lib-storage API. But a quick and dirty way is possible to implement for v2.1 as well, as long as some IMAP extensions aren't used (most importantly rfc5267).

[Dovecot] does dovecot interpret any mail headers specially with maildir?
by Christoph Anton Mitterer 29 Oct '12

29 Oct '12

Hi. For mbox, http://wiki2.dovecot.org/MailboxFormat/mbox#Dovecot.27s_Metadata lists a numer of mail headers: - X-IMAPbase - X-IMAP - X-UID - Status - X-Status - X-Keywords - Content-Length that are treated specially by dovecot. It also suggests, that these should be stripped by the LDA (I guess in order that someone sending you such mail cannot set the status or keywords, or even "attack you" by setting a bogus Content-Length). I wondered, when using maildir, are there any headers that dovecote would treat specially, too? And which I therefore should strip? Thanks, Chris.

[Dovecot] No failover from director to backend?
by Patrick Westenberg 29 Oct '12

29 Oct '12

Hi everyone, short version: Is there no built in failover mechanism for the director service to handle a backend failure? Long version: I have a frontend server running the director service and two backends. Due to maintenance I had to shut down one of the backends which caused connection errors for the users being directed to this backend. I was very surprised as I expected the director to redirect these users to the remaining backend. Am I wrong or is the director not working as expected?

[Dovecot] INBOX permissios woes
by Josep L. Guallar-Esteve 29 Oct '12

29 Oct '12

Hello, I have a dovecot system that uses winbind authentication against Active Directory. I set it up by following the directions in the wiki. That works great. When a new user receives an email, the inbox is created with permissions 600 (rw- --- --) and ownership user:mail , even though I did chmod 02770 /var/spool/mail. And then, when dovecot tries to access the inbox, it throws the error: Oct 29 13:47:59 imap-login: Info: Login: user=<user1>, method=PLAIN, rip=10.0.0.6, lip=10.0.0.26, mpid=29047, secured Oct 29 13:47:59 imap(user1): Error: stat(/var/mail/user1) failed: Permission denied Oct 29 13:47:59 imap(user1): Error: stat(/var/mail/user1) failed: Permission denied Accessing users' Sent, Trash, creating new folders.... all that works fine.

[Dovecot] Overlapping userdb/passdbs
by James Devine 29 Oct '12

29 Oct '12

I have an ldap server for which each entry includes the email address and the username portion of the email address for authentication. Authentication works by username if the username is unique among all the entries. I need to now add some users which must authenticate even if the username is not unique. I figured one way to do this would be to add a second user/pass db which puts further restrictions on the ldap query to make it unique for those users. This doesn't seem to work however as if the user is found in the first ldap query but the password does not match it does not try the second. I would use the password as part of the query but this setup requires me to allow the client to hash the password. Is there a way to do this? Or maybe I am approaching the problem wrong.

[Dovecot] Can Dovecot authenticate against an external email server?
by Marc Perkel 29 Oct '12

29 Oct '12

Just wondering if anyone has done this. I have a spam filtering service where I am now storing spam for users I filter for. It's a filter and forward service so I don't control the recipient's email server. What I would like to do somehow is have the user enter their email address and password and then look up their POP/IMAP server from a database and try to authenticate from it. If sucessful then the user will be able to access their stored spam using Dovecot and Squirrelmail. Any suggestions? Thanks in advance

[Dovecot] Auth caching and password changes
by Angel L. Mateo 29 Oct '12

29 Oct '12

Hello, In my system I have configured auth caching. The problem I have is that whenever a user changes his password, he/she can't login to dovecot after a while and the scenarios described at http://wiki2.dovecot.org/Authentication/Caching are not applied. I have tried also with "doveadm auth cache flush <login>", but it didn't work. He also could to login again if he waits for a time or if I run "doveadm auth cache flush" in the server, flushing all auth information from cache. I have attached the log I had when I changed my password (and suffered the problem). I have attached my doveconf -n too. -- Angel L.

[Dovecot] Configuring Dovecot & Snarf plugin for the first time
by Jeffrey Ross 29 Oct '12

29 Oct '12

I've been using uw-imap for some time on my linux system and have been running into issues with it so I've decided to move to Dovecote, so far it seems to have solved the issues I've been having however I need/want to move the incoming emails out of /var/spool/mail/{user} in the same (or similar fashion) that uw-imap did, and I found the snarf plugin. However whenever I enable the snarf plugin using the example on the wiki page my email is not loaded and when I remove my configuration for snarf my email re-appears. Based upon what I can tell the snarf plugin is either not loading (but I see it listed in the logs) or simply not working (which is probably because its not configured properly). The system is Fedora 16 (x86_64), the MTA is Exim, and Dovecot is 2.0.21 (version supplied with Fedora). I know I'm making a newbie mistake. Any guidance would be appreciated.

[Dovecot] LDA without lookup as non-root?
by E.B. 29 Oct '12

29 Oct '12

Hello, I'm having some problems getting LDA to work without userdb lookups and have a few related questions. This system has all users in MySQL, each user with unique UID/GID, no local users at all. Installation is from apt-get. 1) If LDA is invoked without lookups, is it correct to assume that the "service auth" and "service auth-worker" can be completely removed from dovecot master configuration? (I have tried commenting them out and logging into IMAP, which seems to work, not sure if anyone else needs the auth service) 2) If LDA is invoked without lookups, will I be unable to use Dovecot quota plugin? Does it need to have a user lookup to get quota info? (haven't added quota support, need to take this one step at a time) 3) The interesting part -- I am invoking LDA from Maildrop. See: http://thread.gmane.org/gmane.mail.imap.dovecot/65473 So when invoked, Maildrop has already dropped to the destination UID/GID and the needed paths are available in the environment. However, using as many permutations of calling LDA as I can think of (based on http://wiki2.dovecot.org/LDA ), I always get this: (command line usage error. Command output: lda: Fatal: Couldn't lookup our username (uid=2500) ) The UID is correct for the target user. If I add "-d $LOGNAME" to my LDA callout, I get permission denied on the userdb lookup, which I guess is another issue to work out if I want to go with lookups. But right now I am trying not to. Why does LDA seem to try for a lookup even when I follow the wiki instructions how to call it without a lookup? 3.5) Related question, my users have separate homedir and maildir, both paths are looked up by Maildrop. I think I need to call LDA with "HOME=$DEFAULT dovecot-lda -f $FROM". Is this correct?

[Dovecot] mail open slowly
by Bernics Gábor | Penta Unió Zrt. 29 Oct '12

29 Oct '12

Hello, I have a dovecot IMAP server (relative small hardware: HP Microserver with 6 Gbyte RAM, linux soft RAID1 with 2x 7200 SATA disk) with 100 Gbyte maildirs. Server works fine but sometimes I can open mails slowly (5-10 sec), typical with new mails. It's intresting when I open an another old mail (with 0 sec wait), after new mail open quickly. Is it dovecot mail indexes or I/O problem? Load and CPU use is small typical 0.10, 10%, I see small IO wait. Debian 6.0, Dovecot 1.2.15, fsync and nmap is disable Best Regards, Gabor

[Dovecot] Active Directory 2003 user database and passwords with special characters
by Boris PINON 29 Oct '12

29 Oct '12

Hello everybody, As explained in the topic, i have troubles with authentication of my users. First of all, sorry for my poor english... I'm running dovecot v1.2.15 on a Debian 6 64bits server up to date. My users database is an Active Directory 2003 (it's important to know that because Active Directory can't retrieve users passwords, you have to bind LDAP with a domain administrator). So, i'm using userdb ldap for authenticated my users and it works ! BUT... When an user having a password with special characters like " ² ° § µ à é è ç à â ê î ô û ù ä ë ï ö ü ", authentication does not work. And in my log file : MY_SERVER | mail/info | dovecot | 2012/08/27 10:42:14 | auth(default): cache(my_user,192.168.7.127): plain(RU0975é*) != 'RU0975Ã©*' As you can see, the character é has been replaced by Ã©.

[Dovecot] Problem with sieve. dovecot 2.0.17
by Eliezer Croitoru 28 Oct '12

28 Oct '12

Since I have lots of filtering rules in thunderbird I was thinking of using sieve instead. I want to filter incoming mail into subdirectories. like "from" store at folder "old". the script is: require ["fileinto", "envelope"]; if envelope :is "from" "eliezer(a)test.dom" { fileinto "old"; } else { # The rest goes into INBOX # default is "implicit keep", we do it explicitly here keep; } the result is that the mail is stored in two folders instead of just one, INBOX and old. the logs shows: Oct 23 17:12:26 lda(eliezer(a)ngtech.co.il): Debug: sieve: executing script from /home/vmail/domain/eliezer/home/.dovecot.svbin Oct 23 17:12:26 lda(eliezer(a)test1.dom): Info: sieve: msgid=<5086B3C9.5030909(a)test.dom>: stored mail into mailbox 'INBOX' Oct 23 17:12:26 lda(eliezer(a)test1.dom): Info: sieve: msgid=<5086B3C9.5030909(a)test.dom>: stored mail into mailbox 'old' from unknown reason(or I didnt understood how sieve works?) plugin section from dovecot -n plugin { ... sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +vnd.dovecot.debug +imapflags +relational +comparator-i;ascii-numeric } Thanks, Eliezer

[Dovecot] Locking /var/mail/user issue with postfix and dovecot
by Robert JR 27 Oct '12

27 Oct '12

Hello, I have a question regarding mailbox locking and hope any one can help me to better understanding the locking of mbox My Postfix lock option is fcntl dotlock mailbox_delivery_lock = fcntl, dotlock virtual_mailbox_lock = fcntl, dotlock My Dovecot lock option is fcntl only mbox_write_locks = fcntl mbox_read_locks = fcntl now, when user is download a large mail (20 MB) for example, dovecot locks /var/mail/user with fcntl until the users finish downloading the mail ok here comes my question. While the user is downloading the mail , a mail arrives so postfix make some thing weird 1- Postfix creates /var/mail/user.lock for 5 secs , then postfix defer the mail with reason that the /var/mail/user is locked and then delete the /var/mail/user.lock (after 5 secs) My question is ? why postfix create user.lock although it shouldn't because already dovecot fcntl it … 1- Dovecot locks /var/mail/user using FCNTL 2- Posttix at the same time tries to FCNTL /var/mail/user .. but it fail since dovecot already fcnl it. 3- Postfix at the same time add dot lock /var/mail/user for 5 secs then remove the lock. the question is how come postfix dot lock /var/mail although it couldn't FCNTL the file in the first place ??????? what i was expecting is 1- Dovecot locks /var/mail/user using FCNTL 2- Postfix tries to FCNTL /var/mail/user 3- POSTFIX WILL NOT CREATE DOTLOCK file unless the FCNTL is released by dovecot!!!! Please advise if postfix will dot lock the file even if it couldn't FCNTL the file in the first place…… Regards

26 Oct '12

Hi I've added a server-side feature where authenticated customers sending through our SMTP server have their outbound mail copied to their Sent folder (like Gmail does). The delivery script called by qmail calls dovecot-lda to deliver it to the user's Sent folder. The problem now, is that the Sent folder shows the mail as unread, which MUAs flag (and notify, in the case of some). I've searched the docs and mailing list, but can't find an option to tell dovecot-lda to mark the mail being delivered, as seen/read. If I've missed something, please let me know. If not, then I think it might be a good idea to add a feature to dovecot-lda permitting one to specify delivery to the ./cur subfolder of a Maildir, instead of ./new. Thanks

[Dovecot] Shared folders not shown if "INBOX.shared.%.%" is used with dovecot 2.1.10
by Christoph Bußenius 26 Oct '12

26 Oct '12

Hi, Thunderbird uses the following IMAP command to list shared folders: . list "" INBOX.shared.%.% Dovecot 2.1.10 does not list any folders in response to this command. Dovecot 2.0.21 does list them: * LIST (\HasNoChildren) "." "INBOX.shared.user1.folder" . OK List completed. Both versions list the folders if "*" is used instead of "INBOX.shared.%.%". Because of this issue, shared folders are not shown in Thunderbird. The ACL of the folder in question is ACL "keilrwtscd" for user1 (who is trying to access them using Thunderbird). config: # 2.1.10: /usr/local/dovecot/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-42-server x86_64 Ubuntu 10.04.4 LTS disable_plaintext_auth = no mail_gid = vmail mail_location = mdbox:~/mail mail_plugins = acl mail_uid = vmail namespace { inbox = no list = children location = mdbox:%%h/mail prefix = INBOX.shared.%%u. separator = . subscriptions = no type = shared } namespace default { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = scheme=CRYPT username_format=%u /usr/local/dovecot/etc/dovecot/users driver = passwd-file } plugin { acl = vfile acl_shared_dict = file:/mail/shared-mailboxes } protocols = imap pop3 service auth { unix_listener auth-userdb { group = vmail mode = 0660 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /usr/local/dovecot/etc/dovecot/users driver = passwd-file } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_max_userip_connections = 20 mail_plugins = acl imap_acl acl } Cheers, Christoph -- Christoph Bußenius Rechnerbetriebsgruppe der Fakultäten Informatik und Mathematik Technische Universität München +49 89-289-18519 <> Raum 00.05.040 <> Boltzmannstr. 3 <> Garching

[Dovecot] Small issue with "submission host"
by Raphael Ordinas 26 Oct '12

26 Oct '12

Hi everyone, I'm facing a small issue with the lda/lmtp "submission_host" feature in dovecot 2.0.14. When sending mail to MTA (in case of sieve filter forwarding for example), dovecot pass a RCPT TO command just after the EHLO. He's missing the MAIL FROM command. Therefore, my MTA show me a warning like this : "improper command pipelining after EHLO". How can i solve that ? Regards, Raphael

[Dovecot] Public folders and groups
by b m 26 Oct '12

26 Oct '12

Currently I have dovecot working with Active Directory authentication and public folders with acl. In acl I have the users I want to access the public folders. It'll be easier for me to use one group instead of 50 users but I can't get it to work. From where does dovecot get the "group" attribute for a user? Can it read the groups that a user belongs from AD?

[Dovecot] Snarf plugin
by Jeffrey Ross 25 Oct '12

25 Oct '12

I've now upgraded dovecot from 2.0.21 to 2.1.10 and the good news is I no longer see dovecot crashing when loading the snarf plugin however snarf still does not do anything except make the inbox disappear. I've come to the conclusion that either snarf does not actually work, possible, but I doubt it, or more likely I have a configuration issue preventing it from working. The system is simple, all email is stored in /var/spool/mail/{username} and I want all the mail moved to ~/mbox when the user logs in via imap, similar to uw-imap. Any guidance would really be appreciated.

[Dovecot] Creating Maildir and populating with emails via external Python process
by Bradley Rintoul 25 Oct '12

25 Oct '12

Hello: I'm using Dovecot to provide IMAP services for Thunderbird clients. The user's mail is stored in Maildir format and the individual emails which the user "receives" are actually downloaded and put into the Maildir "repository" using a Python email client (POP3 client). I am trying to create the dovecot-uidlist file and maintain the "next UID" value within it, but I am having trouble with the UIDVALIDITY and the 128 bit mailbox global UID among other things. How can I "seed" a dovecot-uidlist file with these values..? Sorry if the information is not much to go on, please let me know what more information you might need to help point me in the right direction. Thanks, B. RIntoul

[Dovecot] spamc can't seem to call /usr/lib/dovecot/deliver

Hi, My server uses a system comprised of postfix, dovecot and dspam to filter and deliver mail.

[Dovecot] dovecot auth against AD on samba4
by Carsten Laun-De Lellis 24 Oct '12

24 Oct '12

Hi group I am currently running a mail server on ubuntu 11.04 with postfix 2.8.5, dovecot dovecot 2.0.13 and openldap 2.4.23. I have now read about sogo and I am thinking about installing it because of it's native outlook support capabilities. The ZEG appliance wouldn't be an option for me because I use a virtual server from a provider where I can't install my own vm or even an iso. When I go thru the documentation there is a part with installing OpenChange based on samba4. As far as I understood the OpenChange authentication is against the samba4 AD. Actually there is no support in syncing the AD against an OpenLdap Server and I would have to change the OpenLdap port because the AD is listening on port 389. To change the port wouldn't be a big deal, but what i was thinking about to run the dovecot auth also against the samba 4 AD. I searched around on the internet but didn't find a doc yet how to do that. Does anyone here could provide me with a link or a how-to ? Thanks very much in advance.

[Dovecot] Clarifications on Pigeonhole and MySQL lookups
by Sandro Tosi 24 Oct '12

24 Oct '12

Hello, we're scouting if it's possible to use Pigeonhole (currently v0.3.1, as this will be provided with an upcoming Debian package) with MySQL dict lookups with the mail setup we're designing. Our (main) goals are: 1. store the filters on the database 2. allow each user to enable/disable any of the filters set we provide (it's a static set of some general filters, available to all the users; we're currently not providing the possibility to users to write their own filters) For point 1) we already see[1] that's possible, but it uses the map construct that might not fit with our current database structure: we have a domain table (storing the domain info) and a mailbox table (storing the mailbox info, but the username is composed by the local part, stored in this table, and the domain part is a FK to the domain table, using an id). Do you think it's possible to run a join query on domain+mailbox to retrieve the mailbox_id needed to query the table for the filters? Or do we have to create the filter table and store the local(a)domain.ext info there ("relaxing" the integrity relationships between tables)? How do we specify which filters are enabled for any given user? We originally thought of an "Enabled" field on the filter table, but in the example in the doc[1] I hadn't seen a way to do that: it seems like the filter list is specified in the proxy definition - am I wrong? How can we do that? [1] http://hg.rename-it.nl/dovecot-2.1-pigeonhole/file/e9ed5d5cef4b/doc/script-… I think it's enough for now, maybe additional questions will arise going deeper in details :) Thanks in advance, -- Sandro Tosi Product Engineer Shared Hosting Products R&D | Dada.pro eml sandro.tosi(a)register.it

[Dovecot] Maildir hardlinks

23 Oct '12

Hello list, Excuse me for my poor english. I have updated on a test server dovecot 2.0.13 to dovecot 2.1.1. All works fine, but with the new version it seems that dovecot don't do hardlinks when deliver a message to multiple users. I have checked my config and the only rule I can see aboout that is maildir_copy_with_hardlinks = yes in /etc/dovecot/conf.d/10-mail.conf My mail location config is mail_location = maildir:~/MailDir:LAYOUT=fs I tryed using lmtp directly issuing 'telnet localhost 24' and sending a test message to 3 recipients. Then issuing a 'ls -il' in the "new" directory of that users, I saw the inode was not the same. I rechecked my config and take a look in the wiki and in the list for someone who had the same problems, but found nothing. Maybe I did something wrong, but I can't understand what. Can you help me?

[Dovecot] index files created improperly in dovecot 1.2.16
by john roman 23 Oct '12

23 Oct '12

Greetings, It seems to be a problem that ive seen occasionally on the web with few results as to a solution, but im experiencing it as well. Namely, dovecot creates index logs for users with a 600 permission, when it should create with a 700 permission. My indexes are stored in /var/indexes with the directory at 777 permission, the users are identified in MySQL. The error is as follows: Oct 23 09:03:13 mailer01 dovecot: POP3 (johnr(a)testing.com) stat(/var/indexes/j/johnr(a)testing.com/.INBOX) failed: Permission denied (euid=10509305(x10509305) egid=81607(pg199275) missing +x perm: /var/indexes/j) the permissions of /var/indexes/j are 700, owned by the euid and egid effectively. the only file that does not have this permission is in /var/indexes/j/johnr(a)testing.com/.INBOX/dovecot.index.log, at 600.

Hello all, I would like to thank you all for your kind replies and feedback in regards to migrating from a smaller hdd to a bigger one (namely from 72gb to 146gb). I finally found a painless way of doing this. Since I believe that this is still an off-topic post, if anyone is interested in the solution i've adopted for this, let me know by replying to me privately. If, however, you don't mind me posting here, let me know. Many many thanks go to Alexander Hoogerhuis, the "mad Norwegian" :-) who helped me on this too much to describe here.

[Dovecot] (new) director issues in 2.1.10
by Kelsey Cummings 22 Oct '12

22 Oct '12

Timo - I upgraded to 2.1.10 on our director servers two nights ago and apart from errors associated with the directors processes restarting everything looked great for ~24 hours until I failed our the real servers last night to update the nfs mount options for the spools. I followed the suggested procedure for each backend server, just run on one of the directors, which seemed to work as expected. doveadm director add x.x.x.x 0 doveadm director flush x.x.x.x The following errors on the directors that started after this went unnoticed until this AM. director: User bb host lookup failed: Timeout - queued for 30 secs (Ring synced for 36 secs) director: User cc host lookup failed: Timeout - queued for 48 secs (Ring synced for 66 secs, user refreshed 12 secs ago) director: User dd host lookup failed: Timeout - queued for 124 secs (Ring synced for 119 secs, weak user, user refreshed 155 secs ago) director: User ee host lookup failed: Timeout - queued for 79 secs (Ring synced for 119 secs, weak user, user refreshed 113 secs ago) ... User ff host lookup failed: Timeout - queued for 30 secs (Ring synced for 7427 secs, weak user, user refreshed 620 secs ago) This continued, combined with occasional login timeouts (as reported by some internal imap clients.) The login delays/timeouts got bad enough that our load balancers dropped both the servers while I was investigating. They seem to be okay after being restarted. -K

[Dovecot] auth timeout state=2, bad?

[Dovecot] Marking all mail in one folder of public mailbox as read
by Frerich Raabe 22 Oct '12

22 Oct '12

Hi, I'm running Dovecot 1.2.17 on FreeBSD 9 to serve an archive of a few internal mailinglists. The archive is implemented using a public namespace: namespace private { separator = / prefix = inbox = yes } namespace public { separator = / prefix = Lists/ location = maildir:/home/vmail/lists/Maildir:CONTROL=~/Maildir/lists:INDEX=~/Maildir/lists subscriptions = no } As you can see, the CONTROL/INDEX files are stored per-user to allow private \Seen flags. The different mailinglists are all sent to the 'lists' user which has a Sieve script to file them into different folders, so I have directories on my harddisk like /home/vmail/lists/Maildir/.somelist /home/vmail/lists/Maildir/.anotherlist Now, I'd like to mark the mail in *one* of those folders as \Seen by default. If the INDEX files weren't per-user, it would simply be a matter of using 'addflag "\Seen";' in the Sieve script of the lists user. Alas, this has no effect. Hence my question - how can I have the mail of just one mailinglist get marked as "read" for all users? So far, the only option I see is to add a second public namespace, with a different prefix - and this namespace doesn't use private CONTROL/INDEX files. However, I'd like to keep using the "Lists" prefix if possible to avoid too many changes to the clients. -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

The dict is also needed for quota lookup from the database. The only thing which might be omitted is the global quota_rule since it is returned by the userdb/passwd in any case, but I'm not sure what happens if you only configure a "quota_rule2" without configuring a "quota_rule". > My outstanding issue is whenever I as the root mysql user update a > user's quota the other user also gets an update, I noticed with one > the messages column on the other user went from 0 to 2, another time > the quota value went up from 0 to 3500 it seems random. You should not be accounting the actual mailbox usage in the same virtual_users table as the quota is read from. Use *different* column or table name in your dict file where dovecot may write the current storage/message count. > dovecot-dict-sql.conf.ext > > map { > pattern = priv/quota/storage > table = virtual_users > username_field = user > value_field = quota value_field should be current_quota_storage (writable column) > } > map { > pattern = priv/quota/messages > table = virtual_users > username_field = user > value_field = quota_messages value_field should be current_quota_messages (writable column) > I'd like to know why these columns are updating. Dovecot stores the current storage and mailcount in there. These columns should be different from the columns defining the maximum limit. Regards Daniel

[Dovecot] still having difficulties with per-user quotas
by David Mehler 20 Oct '12

Hello, I am trying to get per-user quotas working. My thanks to all who have helped so far. To recap I am running Dovecot 2.1 and Mysql where I've got my virtual users. All virtual users are under the system user vmail with a UID and GID of 5000. Looking over the wiki docs I've added a quota table and got the dict service working, I am not having problems with permissions or the login username and password, all that is working fine. Here's my current doveconf -n output it is producing the following debug error related to the userdb sql query: # 2.1.10: /etc/dovecot/dovecot.conf # XXX dict { quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } first_valid_gid = 5000 first_valid_uid = 5000 hostname = XXX last_valid_gid = 5000 last_valid_uid = 5000 mail_location = maildir:/home/vmail/%d/%n:LAYOUT=fs mail_plugins = " quota" namespace inbox { inbox = yes location = prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { quota = dict:User quota::proxy::quota quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u } protocols = imap service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { mode = 0600 user = vmail } } service dict { unix_listener dict { mode = 0600 user = vmail } } service imap-login { inet_listener imap { address = 127.0.0.1 ::1 } inet_listener imaps { address = xxx xxxx ssl = yes } } service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = vmail } ssl_cert = </etc/ssl/certs/server.crt ssl_key = </etc/ssl/private/server.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { mail_plugins = " quota imap_quota" } Oct 19 15:23:52 auth-worker(29279): Info: mysql(/var/run/mysqld/mysqld.sock): Connected to database mail Oct 19 15:23:52 auth-worker(29279): Debug: sql(xxx,::1): query: SELECT user as user, password FROM virtual_users WHERE user='xxx@domain'; Oct 19 15:23:52 auth: Debug: client passdb out: OK 1 user=xxx Oct 19 15:23:52 auth: Debug: master in: REQUEST 3523346433 29276 1 f5cd16e3f5e078c28d850749e42c86cc Oct 19 15:23:52 auth-worker(29279): Debug: sql(xxx,::1): SELECT concat('*:storage=', bytes, 'M') as quota_rule FROM quota WHERE username='xxx'; Oct 19 15:23:52 auth: Debug: master userdb out: USER 3523346433 xxx quota_rule=*:storage=368485M Oct 19 15:23:52 imap-login: Info: Login: user=<xxx>, method=PLAIN, rip=::1, lip=::1, mpid=29282, secured, session=</xKpcW7MFgAAAAAAAAAAAAAAAAAAAAAB> Oct 19 15:23:52 imap(xxx): Error: user xxx: Couldn't drop privileges: User is missing UID (see mail_uid setting) Oct 19 15:23:52 imap(xxx): Error: Internal error occurred.

[Dovecot] Dovecot 2 and TCP-Keepalive
by Sven Hartge 20 Oct '12

20 Oct '12

Hi! I am about to migrate a perdition-based IMAP/POP3 proxy to Dovecot. Unfortunately some users are behind a firewall/NAT setup which throws away seemingly idle TCP connections sooner than the established default of 24 hours (more likely after 30 minutes ...) resulting in all kinds of weird client behavior. And unfortunately² this firewall/NAT setup is outside of my control and I have no means of correcting this (in my opinion) flawed configuration. Now, with perdition I was able to use the --tcp_keepalive option which totally solved the mentioned weird client behavior. My question is: does Dovecot2 use TCP-Keepalive on its sockets per default or do I need to enable it some way I have not yet discovered? The manual and wiki only talk about "keepalive" in connection with the IMAP protocol and IDLE and my C-fu is too weak to understand the source code. Grüße, Sven. -- Sigmentation fault. Core dumped.

Hello, Can You explain to me how dovecot-lda knows actual size of virtual user directory?

[Dovecot] Question about salted hashes
by Tobias Maffert 19 Oct '12

19 Oct '12

Hello. I'm switching from b1gmail to my own setup which consists of Postfix+Dovecot+MySQL (and maybe VBoxAdm). There are two problems: - b1gmail is using unsalted MD5 hashes. Is there any good way to make my new setup backward compatible?

[Dovecot] Add S=<size> to maildirfile

Hi, in some old Maildir/ I have file without the S=<size> in file name. Is possibile to add the size to the file name with some tools like doveadm? Are there other methods to update these file?

[Dovecot] Emails from invalid local accounts
by Steven Kiehl 19 Oct '12

19 Oct '12

Hi, I'm using dovecot 1.2.9 in a postfix/dovecot setup and I'm having issues with receiving spam where the "from" header contains an address like accounting(a)mydomain.com. Is there some way I can filter out these emails coming from outside our network with an account associated with our network which doesn't exist? Do I just need to configure some custom process to evaluate these addresses, or is there some way either in dovecot or spamassassin to do this? Thanks, Steve K

[Dovecot] lmtp proxy logging
by Jack Bates 18 Oct '12

18 Oct '12

The logging on lmtp and lmtp proxy is pretty limited from what I can see. It seems to handle errors, Connect, Disconnect, and in the case of lmtp delivery, it logs where an email is saved to. The lmtp may be enough, "connect, saved user, saved user..., disconnect", but I was curious if it is worth while to add more info logging for the proxy, primarily which recipients are sent to which proxy. I was thinking of local patching it, but I'll generate up something more inline with official code if it is desired. My thought is to show 1 entry for each recipient, and the destination server chosen. If I recall correctly, the proxy code doesn't actually listen in on the conversation, so logging results would probably complicate the code. Jack

[Dovecot] Problem with process_limit
by FABIO FERRARI 18 Oct '12

18 Oct '12

Hello, i have a problem with the process_limit configuration. Occasionally, it happens that the dovecot.log shows this line: master: Warning: service(imap): process_limit reached, client connections are being dropped So I checked, the process number, with the command: ps auxwww | grep imap | grep -v login | wc -l and it shows 1024. Then, i edited the file /etc/dovecot/conf.d/10-master.conf and set the line process_limit = 1500 I checked if the dovecot had accepted the change with the command doveconf -n | grep process_limit and it shows process_limit = 1500 But it is dropping the connections when they reach 1024 anyway, the configuration parameter is totally ignored. Can anyone help? Am I editing the right parameter? thanks in advance Fabio Ferrari P.S. The version of the dovecot is dovecot-2.0.1-1_118.el5 on Red Hat Enterprise Linux Server release 5.8 (Tikanga).

[Dovecot] real_rip variable addition for dovecot 2.1.10
by Jack Bates 18 Oct '12

18 Oct '12

Timo, Please check the code. I didn't add it, but a real_lip might be useful for some people as well. Also, I notice that pop3-proxy is doing a different xsession than the imap proxy. Is there an xsession standard that is different between the two, or just an oversight in the code? Both send the remote address/port, but only imap proxy sends the local address/port. This patch declares long variable %{real_rip} so that a backend server can declare a different login_log_format_elements login_log_format_elements = user=<%u> method=%m rip=%r lip=%l pip=%{real_rip} mpid=%e %c This is primarily useful for backend servers to log both the rip, lip, and in case of xsession, the real rip. I haven't done extensive testing yet, but as long as nothing does anything weird elsewhere in the code, it should be good. http://www.brightok.net/jbates/dovecot-2.1.10-real-ip.patch dovecot: pop3-login: Login: user=<test>, method=PLAIN, rip=192.168.1.5, lip=::1, pip=::1, mpid=8665, secured Jack Bates

[Dovecot] Difference between Indexing and Rescan in FTS
by Fred Kilbourn 18 Oct '12

18 Oct '12

I've had squat running on dovecot 2.0 and have been updating all users mailbox indexes nighty via cron with this command: doveadm -v search -A text xyzzyx I've just updated to 2.1 and I'm migrating to lucene indexes, but reading the documentation I'm having a hard time understanding the semantic differences between indexing and rescanning. If I were to continue to run an all user all mailbox index every night, would that be appropriate? Would running this every night avoid the need to ever rescan? Should I run rescan instead of index? Should I run both rescan and index? In which order? Best Regards, FredK

[Dovecot] Per user quotas
by David Travers 18 Oct '12

18 Oct '12

Hi All, I keep going round in circles with this. I have quotas up and running but would like to add a couple of per user exceptions but can't figure out how to do it! I am using Open Xchange community edition on top of dovecot and tha tis showing the 200MB limit, if I change it in the dovecot.conf the change is reflected in open xchange, but can't figure out how to change for 1 user. I believe I need to add to a passwd file, but I have added to that and nothing has changed. # dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686 i686 Debian 6.0.5 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/certs/postfix.pem ssl_key_file: /etc/ssl/private/postfix.key login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:~/mail:LAYOUT=fs:INBOX=~/mail/ mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 lda: mail_plugins: quota auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix plugin: quota: maildir:user quota quota_rule: *:storage=200M quota_rule2: Trash:storage=10%% quota_rule2: SPAM:ignore quota_warning: storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2: storage=80%% /usr/local/bin/quota-warning.sh 80 quota_exceeded_message: Quota exceeded, Please delete some emails Any help gratefully received Dave _________________________________________ This email has been scanned for malicious content. _________________________________________

[Dovecot] Dsync clustering
by list＠airstreamcomm.net 18 Oct '12

18 Oct '12

I have not seen mention of using dsync for clustering Dovecot in some time on the mailing list, but I believe Timo was going to write a wiki page when v2.2 became more mature. Does this documentation exist yet, or are there any resources on what dsync replication is capable of at this point (looking on the wiki and google didn't reveal much)? Thank in advance.

Re: [Dovecot] Disconnected for inactivity time.

Easy enough to test. It's non-RFC compliant as one poster points out, so unless you got a good reason to do this like lots of zombie pop3 processes, leave it alone.

[Dovecot] Dovecot sieve and duplicate email subjects
by Benjamin Thomas 17 Oct '12

17 Oct '12

Hi, I'm running a small email server with the help of iRedMail. I can manage sieve scripts from the Rouncube web interface or manually inside the user's personal sieve folder. I have an email account setup to receive automated tasks. Some of these "alerts" occur too often and they have the same subject line, but different senders. This is the rule I am currently using: ##CODE START## # rule:[AutoAlerts] if anyof ( header :matches "Subject" "AutoAlert Type1*", header :matches "Subject" "AutoAlert Type2*", header :matches "Subject" "AutoAlert Type3*" ) { fileinto "INBOX.AutoAlerts"; stop; } ##CODE END## I was wondering if it's possible to gracefully handle duplicate subjects lines (within a given time frame) with sieve filters ? Ideally, I would like the first email of the day with subject ""AutoAlert Type1..." to get moved to the subfolder given above. Subsequent "duplicate" emails would then go into a "duplicate" subfolder. Is this possible with sieve filters ? I could not find anything striking me as obvious while reading the page http://wiki.dovecot.org/LDA/Sieve. Thanks very much for your input.

[Dovecot] Dovecot failed logins delay all logins
by Dominic Malolepszy 17 Oct '12

17 Oct '12

Hi all, I have observed with my Dovecot setup that unique failed logins cause legitimate correct logins to be slowed. I am running two servers, each with two Dovecot instances, a Proxy with Director, and a backend Dovecot. I suspect that the backend instance is throttling connections from the same IP, and because I am running a Proxy, the backend will only see either of the two server IPs. I confirmed this by directly connecting to the backend, to bypass the proxy and rule it. I initiated dozens of unique failed logins from one IP and separately attempted to login from the same IP, and experienced an extended delay during login. At the same time a login from a different IP suceeded imediately. I see nothing in the logs suggesting some sort of process limits were exceeded, however I do see the following proc title for the backend auth process: "dovecot/auth [7 wait, 0 passdb, 0 userdb]" I have increased the mail_max_userip_connections to a very large value however I believe that setting is a per username/ip limit. Is there any sort of setting in Dovecot that I can configure that stops this authentication throttling per IP? Below is the configuration of the backend Dovecot instance. # 2.1.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.5.2.el6.x86_64 x86_64 Red Hat Enterprise Linux Server release 6.3 (Santiago) auth_cache_negative_ttl = 3 secs auth_cache_size = 100 M auth_cache_ttl = 10 mins auth_default_realm = example.com auth_failure_delay = 5 secs auth_mechanisms = plain login auth_verbose_passwords = sha1 auth_worker_max_count = 25 base_dir = /var/run/dovecot/ disable_plaintext_auth = no first_valid_gid = 12 first_valid_uid = 8 last_valid_gid = 12 last_valid_uid = 8 login_greeting = Hello there. login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c mail_fsync = always mail_gid = mail mail_location = maildir:%h/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = " stats" mail_uid = mail mmap_disable = yes namespace { inbox = yes location = maildir:%h/Maildir prefix = INBOX. separator = . } passdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } protocols = pop3 imap service auth { unix_listener auth-userdb { group = mail mode = 0660 user = mail } } service imap-login { inet_listener imap { address = 0.0.0.0 port = 9143 } process_min_avail = 5 service_count = 0 vsz_limit = 256 M } service imap { process_limit = 1000 vsz_limit = 256 M } service pop3-login { inet_listener pop3 { address = 0.0.0.0 port = 9110 } process_min_avail = 5 service_count = 0 vsz_limit = 256 M } service pop3 { process_limit = 1000 vsz_limit = 256 M } service stats { fifo_listener stats-mail { mode = 0600 user = mail } inet_listener { address = 127.0.0.1 port = 24242 } } ssl = no stats_memory_limit = 64 M userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } verbose_proctitle = yes protocol imap { imap_logout_format = bytes_read=%i bytes_send=%o mail_max_userip_connections = 1000 mail_plugins = " stats " } protocol pop3 { mail_max_userip_connections = 1000 } Dominic

[Dovecot] Problem with quota update in dovecot 1.2
by tower 16 Oct '12

Hi A have a problem with quota2 table, working under postfixadmin. When I login into imap server with thunderbird client everything works fine, quota is update when i receive a message, but when I move message to trash or any other folder value for messages field in table quota2 increases +1 instead decreases or have still this same value. Only if I close my imap client value descending -2. I wish to table quota2 will be updated immediately after any operation on inbox. Is there any mistake in my configuration?

[Dovecot] Plugin hooks in login process
by Simone Lazzaris 16 Oct '12

16 Oct '12

Hi all; I've setup dovecot (2.1.10) in a cluster configuration. We have two servers acting as frontend which authenticates users and proxy them to other two servers which handles the "real" work. Users credentials are on a mysql cluster; we have one master, in which read/write queries are processed, and many replicated slave, which process read-only queries. The frontend servers reads users credentials from the read-only mysql slaves. I'd like to execute a query once the client is verified to update the last login data. Right now, that query is executed on the backend servers, via a post-login service: protocols = imap service imap-postlogin { executable = script-login /usr/local/etc/dovecot/postlogin.sh unix_listener imap-postlogin { group = vchkpw mode = 0600 user = vpopmail } } service imap { executable = imap imap-postlogin process_limit = 2048 } Problem is, if I execute the update on the backend, I miss the information regarding the original IP, as I only see the IP of the proxies. I haven't been able to launch the postlogin service on the frontend, so I figured that I can try to write a plugin - that also seems to me the cleanest solution. Looking in the dovecot source code, I noticed that there aren't any hooks in the execution path used by the proxies; I am missing something ? I am the only one missing the presence of this hooks in the auth/proxy process ? I've also thought of a workaround for this problem. One way is to monitor the dovecot logs on the frontend and execute the update asyncronously. One other way is to query directly the main mysql server of the cluster and adjust the query making it call a stored procedure that updates the information in case of successful login. But I'd really prefer to create a plugin, that I'd be willing to share. I attach the configuration of the servers (front and back) generated via postfix -n.

[Dovecot] Dovecot deliver Segmentation fault when arrive the first message
by Alessio Cecchi 16 Oct '12

16 Oct '12

Hi, I have found this strange problem. I'm working with Debian 6, dovecot 2.1.9 and vpopmail-auth. LDA is configured and works fine but the problem is when the first message arrive "dovecot-lda" return a "Segmentation fault", the message is written to the user's Mailbox but the message remains, also, in the queue of qmail (deferral: Segmentation_fault/) and at the second attempt is delivered fine. If disable ACL (acl and imap_acl from mail_plugins) in dovecot.conf "Segmentation fault" go away. Moreover, without ACL at the first delivery folders like Sent, Drafts, Trash, Spam appear immediately. An example, new user: root@demo-vpop ~ # tree /home/vpopmail/domains/qboxdns.it/cecchi2/Maildir/ -a /home/vpopmail/domains/qboxdns.it/cecchi2/Maildir/ ├── cur ├── maildirsize ├── new └── tmp

[Dovecot] Search for substring in header?
by Dave Abrahams 16 Oct '12

16 Oct '12

Hi, According to the IMAP spec (http://tools.ietf.org/html/rfc2060#page-37) if I do a search for "TO isocpp.org" it should find all the messages whose To: field contains the string "isocpp.org", but dovecot is returning me an empty list. However, a search for "TO tm(a)isocpp.org" produces a long list of messages. What am I doing wrong?

[Dovecot] [BUG] Lucene plugin breaks header substring search

According to the IMAP spec if I do a search for "TO isocpp.org" it should find all the messages whose To: field contains the string "isocpp.org", but dovecot is returning me an empty list. However, a search for "TO tm(a)isocpp.org" produces a long list of messages. This behavior is present if I *even load* the lucene fts plugin.

Re: [Dovecot] per-user quotas

Hello, Thanks for your replies so far. Still having issues with per-user quotas. To my Mysql virtual_users table I've added a column quota_kb and for a test user I've added in a value of 250000 going for a 250 megabyte quota. I've tried various sql queries they're returning empty sets not pulling out the information needed. Thanks. Dave.

[Dovecot] fts = squat solr
by Dave Abrahams 16 Oct '12

16 Oct '12

I don't know if this was supposed to have changed with dovecot2, but http://wiki.dovecot.org/Plugins/FTS shows fts = squat solr so, since I have the lucene plugin—"fts = lucene" works by itself—I tried fts = squat lucene but: $ doveadm index '*' doveadm(dave): Error: fts: Failed to initialize backend 'squat lucene': Unknown backend So, is that syntax obsolete, is the wiki wrong, or am I doing something wrong? -- Dave Abrahams BoostPro Computing Software Development Training http://www.boostpro.com Clang/LLVM/EDG Compilers C++ Boost

[Dovecot] POP UIDL
by simon.buongiorno＠gmail.com 16 Oct '12

16 Oct '12

Hi I run a small mail server with Dovecot and postfix. Several of the accounts are popped by an external email provide I use, mostly out habit and also for a bit of redundancy. I have no details on that external server except that it uses exim. Lately, it's been repopping mail from accounts (mail is left on the server so I can use IMAP) at fairly frequent, but undetermined, intervals. Before I take it to them, I want to be sure it's not an error on my side. How can I be sure Dovecot does not have a problem with the UIDL list causing this external server to repop the mail? For the record, I'm not inclined to think it's a Dovecot issue, but since that's the bit I can fix, I'd like to be sure. Cheers Simon

Hello, I have a weird problem in dovecot, Dovecot Hangs while multiple users download mail for same account using pop3 Three persons use 1 same email , and three of them use outlook express to check That specific mail .. Also some times one of the three users check the mail for this Account using imap (squirrel mail) And here comes the problem. suddenly all the three users are unable to check the mail And when the outlook express connect to the pop3 server, they are unable to disconnect And the outlook express keep asking "the server is not responding for 60 mins would you like to wait ? i checked /var/log/maillog, i can see the following errors dovecot: pop3(sales): Disconnected: Storage error during logout. to=<sales(a)domain.com>, orig_to=<sales(a)domain.,com>, relay=local, delay=357, delays=338/0.01/0/19, dsn=4.2.0, status=deferred (cannot update mailbox /var/mail/sales for user sales. unable to lock for exclusive access: Resource temporarily unavailable) When i used lsof | grep sales pop3 4278 sales 10u REG 8,3 22897673 12615705 /var/spool/mail/sales i went to /home/sales/mail/.imap/INBOX , but i didnot find any lock files -rw------- 1 sales sales 944 Oct 7 13:35 dovecot.index -rw------- 1 sales sales 49152 Oct 7 16:57 dovecot.index.cache -rw------- 1 sales sales 14044 Oct 7 16:57 dovecot.index.log 1- So what is exactly the problem? is the problem that three users are checking the same exact mail ? 2- is the problem that 2 users checking mail using pop3 and the third one checking it using imap insame time ? 3- is dovecot locking the inbox file while one of the users getting the mail ? 4- What is the cause of the problem ?

[Dovecot] Where'd the Mail Go?

I checked /var/mail/my_user_name and it wasn't there, either. How do I find it? TIA, John

[Dovecot] Advanced dovecot tricks - spam review/release
by Marc Perkel 16 Oct '12

16 Oct '12

Hi, I'm looking for some advice to do a really advanced trick with Dovecot. I'm not sure if this can be done. I need to describe first. I have a spam filtering company that does front end spam filtering. (Junk Email Filter) I want to add a system where I store a copy of spam on a server and make it available to the customer to review and maybe resent on false positives. I know I could do something simple where I deliver all spam to a domain account and make it available to an administrator. Then if it's a false positive they would drag the message to a "resend" folder. I'll have something the checks the folder one a minute to pick up and resend. However What would be very cool is delivering the spam to individual accounts. So a user who logs in individually can see their own spam. But the admin for the domain would be able to see all users. Maybe the users would appear as folders? Then a master account (me) would be able to log in and see all the domains as folders and the users as folders inside the domains? One thing I can do is deliver the spam to 3 different places so it's visible on all levels. I'm just wondering if anyone out there has any ideas about that. And I'll need an authentication system.

[Dovecot] [sieve] - counting headers

14 Oct '12

In some of my maildrop filters I have rules with weighted scoring[1], but only to count headers (for example to count "Received:" header) ie. all these rules are of form "/pattern/:h,1" Can dovecot sieve do this?

HELP! I have installed sendmail, dovecot, and squirrel mail. The squirrel mail portion of it works just fine, but I would like to have Mozilla Thunderbird as a client. Whenever I try and connect to the server it says "Thunderbird failed to find the settings for your email account." We do have an MX record in DNS pointing to our server. We are using Ubuntu 12.0.4.1, and have Dovecot 2.2.6 sendmail version 8.14.4-2ubuntu2 We are doing this for a class project and it is due by Tuesday 10/16/2012.. Thanks, Justin

[Dovecot] dsync ignores ssh-agent
by Mark Hills 12 Oct '12

12 Oct '12

I use IMAP over SSH, in pre-auth. I wanted to use dsync to offline mail to my laptop. dsync v2.1.10 would always ask for my SSH key/passphrase, ignoring ssh-agent. The culprit is the env_clean() in the stack below. Reading the source, I saw DOVECOT_PRESERVE_ENVS. When used as follows in my script it enables dsync to find my ssh-agent: export DOVECOT_PRESERVE_ENVS="SSH_AGENT_PID SSH_AUTH_SOCK" dsync mirror ssh imap.example.com /home/mark/opt/dovecot/bin/dsync and it now works without asking for password every time. I'm posting here so that anyone else googling for the same problem will hopefully find this, as I couldn't find anything about this in the docs. Also I'm interested in why dsync so aggressively cleans the environment; I tried a naive removal of env_clean() but this breaks basic functions. With this dsync is working very well for offline mail -- combined with alpine and a local exim for the outbound queue :) Thanks -- Mark Breakpoint 2, env_clean () at env-util.c:59 59 if (clearenv() < 0) (gdb) bt #0 env_clean () at env-util.c:59 #1 0xb7df10fc in master_service_env_clean () at master-service.c:454 #2 0xb7df26d4 in master_service_exec_config (service=0x809e7d0, input=0xbffff7e4) at master-service-settings.c:103 #3 0xb7df29be in config_exec_fallback (service=0x809e7d0, input=0xbffff7e4) at master-service-settings.c:153 #4 0xb7df2b65 in master_service_open_config (service=0x809e7d0, input=0xbffff7e4, path_r=0xbffff780, error_r=0xbffff7d8) at master-service-settings.c:206 #5 0xb7df3130 in master_service_settings_read (service=0x809e7d0, input=0xbffff7e4, output_r=0xbffff7dc, error_r=0xbffff7d8) at master-service-settings.c:345 #6 0x0805c672 in doveadm_read_settings () at doveadm.c:275 #7 0x0805c7d6 in main (argc=5, argv=0x809e1c0) at doveadm.c:342

[Dovecot] INBOX.INBOX.Sent causes problems in 2.0
by Christoph Bußenius 12 Oct '12

12 Oct '12

Hi, we have our namespace rooted at "INBOX.". Sometimes, users have folders like "INBOX.INBOX.Sent" or "INBOX.INBOX.INBOX.Sent". I do not know why these folders are created; I suspect it is due to buggy MUAs. If a mailbox like INBOX.INBOX.Sent exists, then in some cases Dovecot counts all messages in INBOX twice. This behavior can be demonstrated as follows: 1) Create a folder named "INBOX.INBOX.Sent" (using the IMAP CREATE command) 2) Save a message to "INBOX" (in my example the message is 7 MB) 3) dovecot-quota contains: priv/quota/storage 7129025 priv/quota/messages 1 4) doveadm quota recalc -u user1 5) Now dovecot-quota contains priv/quota/storage 14258050 priv/quota/messages 2 I.e. the user will experience that his quota fills up very fast. "doveadm -f flow fetch -u user1 'mailbox guid' ALL" prints: mailbox=INBOX guid=040ce73645177850497d000040c59ffc mailbox=INBOX guid=040ce73645177850497d000040c59ffc However, "doveadm -f flow fetch -u user1 'mailbox guid' mailbox INBOX" prints the message only once: mailbox=INBOX guid=040ce73645177850497d000040c59ffc How can we prevent this kind of confusion? What I'd like most is prevent the creation of these weird folders. Most MUAs have problems listing them properly, especially if both "INBOX.Sent" and "INBOX.INBOX.Sent" exist. Dovecot 2.1 does not seem to count anything twice. Cheers, Christoph Config: # 2.0.21: /usr/local/dovecot/etc/dovecot/dovecot.conf doveconf: Warning: service auth { client_limit=4096 } is lower than required under max. load (6224) # OS: Linux 2.6.32-42-server x86_64 Ubuntu 10.04.4 LTS disable_plaintext_auth = no mail_gid = vmail mail_location = mdbox:~/mail mail_plugins = quota mail_uid = vmail namespace default { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = scheme=CRYPT username_format=%u /usr/local/dovecot/etc/dovecot/users driver = passwd-file } plugin { quota = dict:ROOT::file:%h/dovecot-quota quota_rule = *:storage=5G } protocols = imap pop3 service auth { unix_listener auth-userdb { group = vmail mode = 0660 } } service imap { process_limit = 5000 } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /usr/local/dovecot/etc/dovecot/users driver = passwd-file } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_max_userip_connections = 20 mail_plugins = quota imap_quota } And the contents of the "users" file: user1:{plain}secret:::user1:/mail/users/user1:: -- Christoph Bußenius Rechnerbetriebsgruppe der Fakultäten Informatik und Mathematik Technische Universität München +49 89-289-18519 <> Raum 00.05.040 <> Boltzmannstr. 3 <> Garching

[Dovecot] [PATCH] dovadm plugins underlinking
by Natanael Copa 12 Oct '12

12 Oct '12

Hi, Running doveadm on Alpine Linux will show various underlinking errors: /usr/bin/doveadm: symbol 'acl_user_module': can't resolve symbol in lib '/usr/lib/dovecot/doveadm/lib10_doveadm_acl_plugin.so'. /usr/bin/doveadm: symbol 'acl_identifier_parse': can't resolve symbol in lib '/usr/lib/dovecot/doveadm/lib10_doveadm_acl_plugin.so'. ... (complete list is found here: http://bugs.alpinelinux.org/issues/1274) I understand that those are "harmless" (at least as long as you dont use those plugins), and even if some dynamic linkers are forgiving, the doveadm plugin modules are technically underlinked. The lib10_doveadm_acl_plugin.so uses symbol acl_user_module: $ nm -D /usr/lib/dovecot/doveadm/lib10_doveadm_acl_plugin.so | grep acl_user_module U acl_user_module That symbol is defined in lib01_acl_plugin.so: $ nm -D /usr/lib/dovecot/lib01_acl_plugin.so | grep acl_user_module 000000000020fb80 D acl_user_module Which means that lib10_doveadm_acl_plugin.so should be directly linked to lib01_acl_plugin.so.

hi- i'm setting up an imap proxy in front of a novell groupwise server. it seems to so far be partially working, but dovecot is having trouble in certain cases. i expect that it's ultimately due to what i believe is a very poor implementation of imap provided by groupwise [at least based on other experiences in the past] - but that's a big part of why i'd like to have dovecot in between it and clients. below is information collected during starting of dovecot, opening/initial connection from a client [os x mail.app], closing of the client, and stopping of dovecot. os is ubuntu 12.10 development/beta, dovecot is 2.1.7 courtesy of ubuntu's packages. log entries: Oct 11 13:24:33 halo dovecot: master: Dovecot v2.1.7 starting up Oct 11 13:24:49 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14171, TLS, session=<iHgu2cvLlwAKRChu> Oct 11 13:24:50 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14174, TLS, session=<t1E/2cvLoQAKRChu> Oct 11 13:24:51 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14176, TLS, session=<OZlM2cvLqgAKRChu> Oct 11 13:24:51 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14178, TLS, session=<d3NU2cvLsQAKRChu> Oct 11 13:24:51 halo dovecot: imap(jdoe): Connection closed in=16 out=350 Oct 11 13:24:52 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14180, TLS, session=<oxNa2cvLtAAKRChu> Oct 11 13:24:52 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:24:52 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14176 killed with signal 11 (core dumped) Oct 11 13:24:57 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:24:57 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14178 killed with signal 11 (core dumped) Oct 11 13:24:57 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14182, TLS, session=<FUCv2cvLuAAKRChu> Oct 11 13:24:58 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:24:58 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14180 killed with signal 11 (core dumped) Oct 11 13:25:03 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:25:03 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14182 killed with signal 11 (core dumped) Oct 11 13:25:03 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14184, TLS, session=<DQkF2svLuwAKRChu> Oct 11 13:25:03 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:25:03 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14184 killed with signal 11 (core dumped) Oct 11 13:25:09 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:25:09 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14174 killed with signal 11 (core dumped) [repeats] Oct 11 13:25:27 halo dovecot: dns-client: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: dns-client: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: master: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: auth: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: config: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: ssl-params: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: anvil: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: log: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) gdb backtrace: ~ >gdb /usr/lib/dovecot/imap /var/cache/imapproxy/jdoe/core GNU gdb (GDB) 7.5-ubuntu Copyright (C) 2012 Free Software Foundation, Inc.

[Dovecot] per-user quotas
by David Mehler 12 Oct '12

12 Oct '12

Hello, I've got quotas set up on an all-user basis on my system, it's a Postfix, Dovecot, Mysql virtual users setup. Currently I have each user getting a 1GB quota with these settings in 90-quota.conf: plugin { quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M } plugin { quota = maildir:User quota } While this works it's not what I want for all users. Say I add a virtual user called user1 to the mysql database but he's a test user and I only want that user to have 25 megabytes of storage, reading the wiki on quotas per-user items such as for example in a database overrides the global items above, is this right? If so, I'm hoping I'm not going to have to redo my entire user database, some users will have per-user quotas while I'll let others have the global quota. Thanks. Dave.

[Dovecot] Feature Request
by Marc Perkel 11 Oct '12

11 Oct '12

It would be handy (for me) if there were a userdb where a directory structure defined the db. userdb stat { mail_location=maildir:/fakedir/%d/%n:INBOX=/email/%d/%n:LAYOUT=fs } userdb stat { mail_location=maildir:/email/%d/%n:INBOX=/email/%d/%n:LAYOUT=fs } The idea being that if the first directory doesn't exist then it will try the second one.

[Dovecot] Multiple Maildir?
by Marc Perkel 11 Oct '12

11 Oct '12

OK - Getting close to everything working in my weird configuration. Here's a problem I'm still having. I'm authenticating with this: userdb { driver = sql args = /etc/dovecot/master-combined-sql.conf } Default mail location: mail_location = maildir:/fakedir/%d/%n:INBOX=/email/%d/%n:LAYOUT=fs However - what I'd like to do is if the mail location doesn't exist then I want to try a second mail location: mail_location = maildir:/email/%d/%n:INBOX=/email/%d/%n:LAYOUT=fs How do I do that? Thanks in advance

[Dovecot] Shared Squat index for public mailboxes
by Frerich Raabe 11 Oct '12

11 Oct '12

Hi, I'm running Dovecot 1.2.17 for serving mail via IMAP as well as for providing access to a mailing list archive. The archive is implemented as a public read-only mailbox with per-user index files (i.e. the \Seen flags are per-user). I recently enbled the Squat plugin to accelerate searches in the message bodies and noticed that every user (I'm using a virtual user setup) gets his own dovecot.index.search and dovecot.index.search.uids copies. Is it possible to share those files among all users of the system? The squat plugin appears to store the search indices among the other index files (as explained on http://wiki.dovecot.org/Plugins/FTS/Squat) no matter what; I considered storing a central copy of the index files somewhere and then creating symlinks for all users. It should be ok as far as file-permissions go since all mail is owned by a single vmail system user, but I wonder whether the indices are really the same (I noticed their md5 checksums differ) and whether there may be file locking issues in case two users search message bodies simultaneously. Can anybody shed some light? -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

[Dovecot] memory allocation in new thread
by . . 11 Oct '12

11 Oct '12

Hi! I have some problems with memory allocation. I create new thread in cidir storage and call malloc(), and it fails to allocate even 1 byte. What can cause this problem? Dovecot vesrion is: 2.1.10 (130563b592c9+) Sample code looks like this (I also link to pthread with: -pthread): #define TEST_MALLOC() \ { \ void *p; \ p = malloc(1); \ if (!p) { \ i_info("%s: malloc() failed", __FUNCTION__); \ } else { \ i_info("%s: malloc() succeeded", __FUNCTION__); \ free(p); \ } \ } #include <pthread.h> static void *test_pthread_malloc_func(void *data_) { TEST_MALLOC(); return NULL; } static void test_pthread_malloc() { int ret; pthread_t tid; TEST_MALLOC(); ret = pthread_create(&tid, NULL, test_pthread_malloc_func, NULL); if (ret) { i_info("failed to start thread"); } else { pthread_join(tid, NULL); } } I call test_pthread_malloc() function. It produces following output: Oct 11 12:56:15 imap(guest): Info: test_pthread_malloc: malloc() succeeded Oct 11 12:56:15 imap(guest): Info: test_pthread_malloc_func: malloc() failed

[Dovecot] Irrelevant information filling logs
by 3.listas＠adminlinux.com.br 11 Oct '12

11 Oct '12

Hi, I have a "Ubuntu10.04 + dovecot-2.0.13" configuration in my server. My mailbox server is shared by ~ 10k domains. It works fine with ~50k accounts. There is a lot of logs of "quota exceeded" like this: Oct 10 13:00:56 mailboxserver5 dovecot: lmtp(29105, user@mailboxserver5): Error: ifcIN1NxdVCxcQAAMBx7mQ: sieve: msgid=unspecified: failed to store into mailbox 'INBOX': Quota exceeded (mailbox for user is full) These messages are not important to me. But these messages fill the log files, damaging the display of messages that could be important. Is there a way to send specific Dovecot errors on specific files or just discard them? Thanks -- Thiago Henrique adminlinux.com.br

[Dovecot] some questions on AOX or rather a mail system setup
by Christoph Anton Mitterer 11 Oct '12

11 Oct '12

Hi folks. Perhaps you find some time to look into this,... I'm trying to plan my mail system and would have some questions. The overall idea is about the following: - There is a (internet) server, which is the MTA (which will be postfix) and imap and/or pop3 server (which shall be, guess, dovecot ... AOX comes in later). - Any spam filtering, virus-scanning, mail filtering happens on that server. - I have not yet decided on whether to use maildrop for this or Sieve. Maildrop is nice, but has one major deficiency which I don't know how to work around. - A few clients (that means I won't serve 100 of users) connect to that server via imap and should see all mails, etc. already in some fancy sorted hierarchy (that means filtered into different directories). So far nothing complicated. But now... - Apart from spam, I never delete mail; and because I'm subscribed to many lists, I get a lot of mail. - Storage on my server is limited and it's located somewhere at my ISP, so I generally do not trust it with respect to safety... For both reasons, I want the canonical archive of all mail to be at home at some local server. - The local server should also be an imap server, so that I can access the archive from may computers at home. - The local server won't be available from the internet. - The local archive should have the same folder hierarchy as the internet server (I'd prefer not to filter twice). - The local archive might be AOX... Mail Flow: - I generally want to have _all_ mail (which is not sorted out because of being spam) to be archived at the local server. - But(!) I want to selectively keep (in addition) mail at the internet server. For example I may want to select the folder that contains all mail form some friend to be kept online completely. But I may want to decide that mailinglists keep only the last 10 days and/or 1000 messages of mail. - The idea is, that the local server regularly (when it is online/running) catches new mail from the internet server... and stores it in the archive. - So apart from new mail that has not yet been read, that local archive contains always all mails that are also on the internet server... the later may contain (for specific directories) the same, or just parts of. - The MUAs will then have two imap accounts, one to the internet server and one to the local archive,... each one being usable, depending on where I am. 1) This is where my first problem arises: How can I implement that mail flow, especially: - How do I secure that all mail is read from the internet server (i.e. that nothing is "forgotten"? - How do I make sure that no mails are retrieved twice (or more)? A problem which I often had with pop, when the mail client crashed during sync? - Further it must be secured, that when I delete something on the internet server, it is NOT deleted on the local server (on the next mail-fetching).... this is why I don't use the word "sync". a) One stupid solution would be, that I duplicate all mail on the online server,... one part is for staying online, one part is for being fetched to the local archive. As soon as it was fetched... that copy gets removed (always). That solution would give a clean and secured separation of both? b) I don't think offlineimap or any other caching-like solution is the right thing... especially as one must always fear that such a cache may be accidentally wiped. Are there better solutions than (a)? 2) Problem would be already a refinement of a working solution for (1) (but obviously not when using (1).(a) ). When e.g. reply to or forward a mail using the online server,... and that mail had already been fetched,... can I make the flag synced? 3) Is AOX suitable for the local server? - I couldn't use maildir locally, because I loose just to much space to the block fragmentation. But I guess I won't have this problem with the DB backend. a) Is AOX able to manage a really big folder hierarchy that basically ever keeps growing... with easily several 100k mails per folder... and that is in total already over 100GB? I read that e.g. dovecot would have more performance problems with that. b) I would prefer to have fast full text search. Does AOX provide this? I read that IMAP has limitations which make full text search not really usable via it? Further, I remember some dovecot wiki page that showed a comparison which said that both do not perfectly implement imap. Thanks a lot, Chris.

I don't think I understand. Right now the problem is the password retrieved from LDAP cannot be hashed to compare against what the user sent because it is encrypted.

[Dovecot] LDAP encryption
by James Devine 09 Oct '12

09 Oct '12

We have an LDAP server that contains AES encrypted passwords. So far I've been able to use this by adding a passdb module that encrypts the user's password prior to ldap comparison. Now I am looking at supporting client-side encrypted passwords. To do this I need to decrypt the password returned by LDAP. Is there a way to insert a module to do this decryption between ldap returning and the auth mechanism?

[Dovecot] Master User Question

OK - I'm trying to do weird stuff so rather not answer why I'm doing this. Trying to log in using a master user: user@example.com*master@master.com When debugging the master authenticates - but then it tries to authenticate user(a)example.com and it's not found. And - it is true that the user doesn't actually exist. What I want to do is allow it to log in without checking if the user exists, just on the credentials of the master. I'm not quite understanding what the login attempt for user(a)example.com is trying to do. Is it looking for more necessary information? Hope I asked this clearly enough. Thanks in advance.

[Dovecot] Large subjects increase memory-usage and enlarge index-files
by Peer Heinlein 08 Oct '12

08 Oct '12

Several times we already had the problems, that accounts with more the 1.3 or 1.7 billion e-mails in one folder run out-of-memory, even if vsize_limit of 750 MB is set. In this case, the lmtpd-process haven't been able to allocate more memory to read/write/update the index-files and crashed (and the index-files become corrupted at the end.) [Please -- don't discuss about the need of INBOXes with 1.7 million (unread) e-mails (don't discuss that with ME. Personally, I agree, that there's NO need for that...).] But: We also noticed accounts with ~ 300.000 e-Mails running out of memory in the same situations. This happends, if the subject is very large (subject or some other header attributes). And: We've been able to reproduce out-of-memory-Problems with just 13.000 e-mails with VERY long subjects (e.g.: network monitoring status informations), even with a vsize_limit of 750 MB (which is already very much). 13.000 e-mails isn't very much. And it's easy to inject several thousands of prepared e-mails. Having many mails for accounts with huge (and broken) index-files slows down the delivery rate VERY much and increases the need for memory and cpu resources and I/O very much. So: This could be used for a very easy to do denial-of-service attac against Dovecot-based mailservers. I don't have a clear solution for that, Dovecot needs the subject information in its index files. But it looks like, it isn't a good idea to put the whole subject into the index. Maybe it's better/necessary to use just the first 50-70 characters for that and to keep the rest away from the index? I think I would prefer that even if that means, that accessing those folders with "special" e-mails will become slower because Dovecot has to get those informations directly from the e-mail. This performance issue is just a problem for the user. But crashing lmtpd-processes and lowering the delivery rate is a *real* problem for the whole IMAP-cluster.

[Dovecot] [OT] How do I convert maildir to bsmtp format?
by Marc Perkel 08 Oct '12

08 Oct '12

Here's what I'm trying to do. I have a spam filtering operation as a front end for other servers. I've created a virtual server for spam storage where the user will be able to log in using squirrelmail/dovecot to review and release their spam. The email is stored in maildir format. Piecing it together I can use squirrelmail to pipe the email into something so that if a use finds a false positive they can hit the "release" button and the message is sent on to the recipient. Squirrelmail sends the message as you would receive it as stored in maildir format. I need to take this format and translate it to send it on to the user. Wondering what is the best way to do that. Something that translated it into bsmtp format would be great. I'm sure thare must be something out there. I just haven't found it yet. Thanks in advance.

07 Oct '12

Hello list, I've just finished to install Dovecot and things seems to work so far. After some little efforts though. My version is 2.0.20 Question 1: I'm trying to tighten the security a little bit and added in dovecot.conf login_trusted_networks = 192.168.1.0/30 Then restarted Dovecot My client has the IP 192.168.1.20 and it's still able to retrieve emails. I expected it to be forbidden. Am I missing something ? # dovecot -n | grep trust login_trusted_networks = 192.168.1.0/30 Question 2: I feel that Dovecot is slow. I'm doing my test with my iphone as an imap client. Test 1: I retrieve a mail on a remote server provided by a hosting company, it takes 2 seconds Test 2: I retrieve a mail on my server which is on my LAN, the mail includes a few letters in the subject and a few letters in the body. The action takes about 8 seconds. It's quite subtule to measure so first I would like to know if Dovecot tries to do a dns reverse lookup or something like that. And it would explain the overhead. Thank you

I'd like to eliminate the subscription file and have it just list the folders that are there. How do I do that? Thanks in advance.

[Dovecot] doveadm purge -A via doveadm-proxy director fails after some users
by Daniel Parthey 06 Oct '12

06 Oct '12

Hi, we have configured userdb and passdb in the director and try to iterate all users and pass the "purge" command via doveadm proxy to port 19000 on the correct director backend host. A single purge -u username(a)example.org via doveadm-proxy works correctly, but iterating over some users with -A fails.

failed: Internal error occurred. Refer to server log for more information. The wiki http://wiki2.dovecot.org/Services#doveadm states that the privileges are (temporarily) dropped to the mail user's privileges after userdb lookup. It seems that from the second purge on which is passed over a single doveadm connection, the user lookup fails. It also seems a bit strange, that the "-A" parameter can be observed in the doveadm tcp stream to the backend, since iteration should be already done in the director and the backend should purge only a single user: D username(a)example.org purge -A Is there a bug or have I misconfigured/overlooked something? Configs of mailbox backend and director are attached. Kind regards Daniel

[Dovecot] horde sync status ?
by Spyros Tsiolis 05 Oct '12

Hello all, I had a quick look at the horde site and noticed that horde is being advertised as, let's say, "smartphone friendly". Does anyone know if the newest horde version can "talk" to smart phones in regards to e-mails ? In other words, can a user owning a smartphone get his/her e-mails on it apart from the webpage ?

[Dovecot] bug formatting results when using doveadm-server
by Angel L. Mateo 04 Oct '12

04 Oct '12

Hello, I have a infrastructure using director in front of backend servers. So I normally run doveadm commands in director servers, not the backends. The problem I have is when I try to concatenate commands like this: doveadm search -S /var/run/dovecot/auth-userdb -u ${user} SAVEDSINCE 5w | while read guid uid; do doveadm fetch -S /var/run/dovecot/auth-userdb -u ${user} size.physical mailbox-guid $guid uid $uid; done The problem is that although when I run doveadm search command in the backend server I correctly get the list of mails, each line with the mailbox-guid and the uid of the message, when I run the same command in the director server, format of the list is corrupted and there are lines that contains just the mailbox-guid and the next the uid (of the previous) and the mailbox-guid of next, and so on. Like: e62e0d3834ed094e5c7900007efb8a67 66 e62e0d3834ed094e5c7900007efb8a67 71 e62e0d3834ed094e5c7900007efb8a67 74 e62e0d3834ed094e5c7900007efb8a67 75 e62e0d3834ed094e5c7900007efb8a67 77 e62e0d3834ed094e5c7900007efb8a67 78 e62e0d3834ed094e5c7900007efb8a67 so I can't postprocess correctly the output. I think it could be a bug in the communication between the doveadm client and server. PS: As the time of writing this email, I have realized that I could use fetch command directly. But, anyway, I want to report the problem/bug so it can be fixed.

[Dovecot] possible nfs issue
by Cor Bosman 04 Oct '12

04 Oct '12

Hi all, we've started receiving complaints from users that seemingly use more quota than they actually have. We noticed that these users have (in some cases many) .nfs files in their mailspool. Some of our admins checked their own dirs, and noticed them there as well. This could of course be unrelated to dovecot (kernel issue, netapp issue) but maybe somehow has an idea about if dovecot could cause this. This has been going on for at least a year, not really enough to notice before now. root@userimap1# find . -type f|grep -i .nfs ./cur/.nfs00000000003967ad003c0603 ./cur/.nfs000000000757b44b003be609 ./cur/.nfs00000000035e89bd003be60b ./cur/.nfs000000000796251c003be60c ./cur/.nfs000000000796251f003be60e ./cur/.nfs000000000262f9a1003be33a ./cur/.nfs00000000096513f3003be524 ./cur/.nfs0000000007962525003be60f ./cur/.nfs0000000003e7d8ab003be62b ./cur/.nfs00000000026f4fad003be50d ./cur/.nfs0000000000bdaeab003c0611 ./cur/.nfs0000000005da42c7003be525 ./cur/.nfs0000000003d74729003be526 ./cur/.nfs000000000229769e003be535 ./cur/.nfs000000000440969e003be516 With NFS these files are created when a file gets unlinked, but another process still has it open. It disappears as soon as the other process closes it. For some reason they dont disappear. As far as I can tell we've had no server crashes that could explain this. One possible theory is that a rename happens after an unlink. In that case the file remains. This could possibly be a dovecot issue. Anyone else with NFS mailspools seeing this? Cor

[Dovecot] LDA vs LMTP index files
by list＠airstreamcomm.net 03 Oct '12

03 Oct '12

In the docs it states that LDA " ...takes mail from anMTAand delivers it to a user's mailbox, while keeping Dovecot index files up to date." I am wondering if LMTP also interacts with the Dovecot index files and keeps them up to date?

[Dovecot] [PATCH] Add SCRAM-SHA-1 password scheme
by Florian Zeitz 03 Oct '12

Hello, attached is an hg export on top of the current dovecot-2.2 branch, which adds support for a SCRAM-SHA-1 password scheme. Ideally I'd want doveadm pw's rounds flag to apply to this, but that's currently specific to the crypt password scheme, so I left it out for now. Regards, Florian Zeitz

[Dovecot] Syntax for doveadm auth cache
by Angel L. Mateo 03 Oct '12

03 Oct '12

Hello, What is the correct syntax of doveadm auth cache command? According to command line help: usage: doveadm [-Dv] [-f <formatter>] <command> [<args>] altmove [-u <user>|-A] [-S <socket_path>] [-r] <search query> auth [-a <auth socket path>] [-x <auth info>] <user> [<password>] auth cache but when I try to run doveadm auth cache, then I'm asked for a password, so I think the command is trying to authenticate cache user. Moreover... according to previous mails (thread http://www.dovecot.org/list/dovecot/2012-June/066691.html) there is a patch to remove a specific user entry from cache. This patch I think is included in dovecot 2.1.9 (which I'm running) and the syntax is (I think): doveadm auth cache flush <user> 4 cache entries flushed So I'm running this command. Whenever I run it, I get the message that 3 (sometimes, is 4) entries are removed, but user information isn't really reloaded and I doubt it is really removed from cache (I have the user in a passwd-file and information used by imap processes is still the old one, no the new one, changed before the flush) -- Angel L.

I conjectured that these attempts are SMTP AUTH, not IMAP, brute forcing. Are you using the dovecot's SASL feature to authenticate outgoing Email (i.e. via Postfix?). Maybe you verify this hypothesis by checking the Postfix logs. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Spurious " Renaming not supported across conflicting directory permissions"
by tlhackque 02 Oct '12

02 Oct '12

Dovecot 2.1.10 Client = Thunderbird. Local disks. mbox format. Attempted to rename a folder, failed with: CANNOT Renaming not supported across conflicting directory permissions I don't understand why this should happen. o I was renaming within a directory - the attempt was to rename "Domain Names &- SSL Certificates" to "Domain Names". No directory was specified o The reason the directory has g=s is for dovecot - so that the 'mail' group (12) will stick to any files created. I was getting more understandable permission failures before I added it. Since 's' doesn't apply to files, I don't see why this should be viewed as a conflict. o If I chmod g-s the directory, the command succeeds.

[Dovecot] noisy auth-worker messages in logs (dovecot 2.1.8 FreeBSD)
by Philippe Chevalier 02 Oct '12

02 Oct '12

Hello, I don't know if it's been addressed before, but anyway : In my dovecot setup, I have local and virtual users. So, I need multiple passdb backends. Namely, passwd for the local users and ldap for the virtual users. passdb { driver = passwd } passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf driver = ldap } Everything work correctly : when a user logs in (imap/pop3) there's a lookup in passwd and if it fails there's a lookup in ldap (if I understand the process correctly), which eventually succeeds. Except that every time a virtual user logs in, dovecot logs an error, like : dovecot: auth-worker(99126): Error: passwd(xxx(a)domain.org,12.34.254.255): getpwnam() failed: Invalid argument I guess it's because the login is a full email that getpwnam fails. Anyway, the user logs in just fine. But I would like to know if/how I can get rid of the messages filling my logs ? I tried : auth_debug_passwords = no auth_verbose = no But no dice. I used dovecot 1.x before and there was no such messages. Thanks for any advice.

The logs on the proxy server show: Sep 27 19:55:12 proxy1 dovecot: lmtp(9398): Connect from 69.8.2.71 Sep 27 19:55:24 proxy1 dovecot: lmtp(9398): Error: lmtp client: connect(lmtp, 7025) failed: Connection refused root 9398 1102 0 19:53 ? 00:00:00 dovecot/lmtp The proxy server is hard coded (not director in this case). I purposefully shut it down to see how the system would handle failures. Unfortunately, it appears that the process just hangs there. For fun, I tried a separate protocol lmtp option in the config to try proxy_timeout. It made no difference. Missing some error handling? protocol lmtp { passdb { driver = static args = proxy=y host=%s nopassword=y proxy_timeout=120 } } Jack

[Dovecot] Logging IP address for failed login
by Scott Neville 01 Oct '12

01 Oct '12

Hi, I am trying to use the logs to show the IP that brute force activity comes from, but Im not succeeding. I have read the archives and seen the advice others have had. I can see logs for repeated bad logins, but I need the IP address from the attempts. dovecot 2.0.12 / CentOS 5.4 / imaps only (993) I have tried a bunch of different combinations of 10-logging.conf settings. This is what I have currently (that does not work the way I want): auth_verbose = yes #auth_verbose_passwords = no #auth_debug = yes #auth_debug_passwords = no #mail_debug = no I *dont* want to see the passwords, either failed or successful. I just want to see failed logins for whatever reason and the IP they came from. In /var/log/maillog I get lines like this: Oct 1 04:19:12 olive dovecot: auth: pam(marketing): unknown user Oct 1 04:19:17 olive dovecot: auth: pam(marketing): unknown user When i had debugging turned on, I would get lines like this: Sep 9 01:14:59 olive dovecot: auth: Debug: passwd(dbelan,62.128.300.94): lookup but only for successful logins. The brute force attempts dont log like that: Sep 16 00:02:57 olive dovecot: auth: Debug: pam(backup): lookup service=dovecot Sep 16 00:02:57 olive dovecot: auth: Debug: pam(backup): lookup service=dovecot Sep 16 00:02:57 olive dovecot: auth: Debug: pam(backup): #1/1 style=1 msg=Password: Sep 16 00:02:57 olive dovecot: auth: Debug: pam(backup): #1/1 style=1 msg=Password: Sep 16 00:02:57 olive dovecot: auth: Debug: pam(backup): lookup service=dovecot Sep 16 00:02:57 olive dovecot: auth: Debug: pam(backup): #1/1 style=1 msg=Password: Sep 16 00:02:58 olive dovecot: auth: pam(backup): unknown user No IP anywhere in that. fail2ban seems to rely on the pop-login or imap-login lines to pull the IP from. I get an imap-login for my real logins: Oct 1 12:38:56 olive dovecot: imap-login: Login: user=<dbelan>, method=PLAIN, rip=62.128.300.94, lip=204.152.189.165, mpid=20360, TLS but no similar line for the failed logins. So is this a dovecot logging configuration combination I need to find? Is it getting lost in pam? Is it specific to CentOS? Any help appreciated - happy to read up on it myself, but would need a pointer, since the docs so far either assume I get an imap-login line for failed logins which I dont, or they assume I just want to see the repeated attempts/passwords. Scott.

[Dovecot] Log NAT IP address?
by Charles Marcus 01 Oct '12

01 Oct '12

Hi Timo/everyone, Currently we are logging the remote IP, but is there a way to show the IP address that the NAT connection is coming from? The reason I ask is, we are changing ISPs, and I would like to see in the logs when an external connection is coming from our OLD ISP connection, and when it is coming through our new one. We have a Watchguard firewall, and I have both External connections setup and working, and have just pointed our DNS records to the new public IP, and would like to be able to see which WAN connection/IP they are coming from. Thanks, -- Best regards, Charles

[Dovecot] Problem: dovecot-lda doesn't auto-create folders
by Karim 'Kasi Mir' Senoucci 01 Oct '12

01 Oct '12

Hello everyone, I recently updated to dovecot 2.0.19 (in fact, I updated the whole system to Ubuntu 12.04 LTS, I am using the dovecot from the Ubuntu packages) and just today found out that the dovecot-lda for some reason doesn't auto-create missing folders anymore as it did with my old installation (1.0.10). I have a "system users" layout and send my mails through a user-specific procmail filter. Every delivery in those filters is done via dovecot-lda using a line list this: > |$DELIVER -d archive -m lists.hylafax-`date "+%Y%m"` where $DELIVER is set to > DELIVER="/usr/bin/sudo /usr/lib/dovecot/dovecot-lda" (I use the sudo because some of the procmail lines deliver the mail to folders in a different user's mailbox.) This works fine for all users, unless the mail folder to be delivered to doesn't exist yet. Here's an example of such a delivery attempt: > Oct 01 10:57:09 lda: Debug: auth input: archive > system_groups_user=archive uid=1002 gid=1002 home=/home/archive > Oct 01 10:57:09 lda(archive): Debug: Effective uid=1002, gid=1002, > home=/home/archive > Oct 01 10:57:09 lda(archive): Debug: Namespace : type=private, > prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes > location=maildir:/home/archive/Maildir > Oct 01 10:57:09 lda(archive): Debug: maildir++: > root=/home/archive/Maildir, index=, control=, > inbox=/home/archive/Maildir, alt= > Oct 01 10:57:09 lda(archive): Debug: none: root=, index=, control=, > inbox=, alt= > Oct 01 10:57:09 lda(archive): Debug: Destination address: xxx(a)xxxx.de > (source: user@hostname) > Oct 01 10:57:09 lda(archive): Debug: Namespace : > /home/archive/Maildir/.lists.hylafax-201210 doesn't exist yet, using > default permissions > Oct 01 10:57:09 lda(archive): Debug: Namespace : Using permissions > from /home/archive/Maildir: mode=0755 gid=-1 > Oct 01 10:57:09 lda(archive): Debug: Namespace : > /home/archive/Maildir/.lists.hylafax-201210 doesn't exist yet, using > default permissions > Oct 01 10:57:09 lda(archive): Debug: Namespace : Using permissions > from /home/archive/Maildir: mode=0755 gid=-1 > Oct 01 10:57:09 lda(archive): Info: > msgid=<201210010954.02813.hylafax_resp(a)earthshod.co.uk>: save failed > to open mailbox lists.hylafax-201210: Mailbox doesn't exist: > lists.hylafax-201210 > Oct 01 10:57:09 lda(archive): Info: > msgid=<201210010954.02813.hylafax_resp(a)earthshod.co.uk>: saved mail to > INBOX Can anyone tell me what goes wrong here and how to fix it? From what I could find out dovecot-lda should auto-create those mailbox folders, but somehow it doesn't. Any help is appreciated. Thanks in advance Kasi Mir

[Dovecot] Dovecot Authentication through different IMAP server?
by Marc Perkel 28 Sep '12

28 Sep '12

Just wondering - is there any way for a dovecot server to authenticate against a different IMAP server? Here's what I'm thinking. I run a spam filtering service and thinking about a way to give users access to their stored spam on my servers. However real email is forwarded to their server, So I'm wondering if I can configure dovecot somehow to do a back end authentication to their email account to gain access to their spam. Open to suggestions

[Dovecot] Hanging IMAP sessions on Mac OS X with dovecot 2.1.10 - worked fine with 2.0.15
by Clemens Schrimpe 28 Sep '12

28 Sep '12

Ok, here's a toughie: Out of a whim (and because of the bad weather) I today decided to upgrade my completely functioning 2.0.15 installation on my Mac OS X 10.6.7 system. NB: It's not a Mac OS X "Server", as sold by Apple - I have compiled my dovecots myself for quite a while. Anyhow: At first everything appeared to work fine after the upgrade. Up until I created a new user and -while testing- SELECTed his INBOX. The SELECT was "stuck". Though the process seemed to be alive I could only get rid of it with a "kill -9 <pid>". The same happened when selecting a newly created mailbox on any of the other (otherwise functioning) accounts, so the problem had nothing to do with the new account, but rather with the fact, that it's INBOX was empty. Using dtruss and gdb I found out, that the dovecot process was trying to obtain a GUID and in the course of doing so invoked gethostbyname(), which intern caused a lot of "mach message" handling and somewhere, deep down there, the process was stuck. Well, that led my to believe, that there was something wrong with the -so called- "mach bootstrap context". I usually start dovecot from with a (home-brewn) startup-script, which invokes it (practically) like so: sudo /usr/libexec/StartupItemContext dovecot (again: all this was working fine under 2.0.15) Now with 2.1.10, when I manually invoke dovecot with just sudo dovecot Everything appears to work fine - at least the sessions don't get stuck any more. But as soon as I logout (with dovecot still running in the background) it loses it's "mach bootstrap context" and finds itself unable to perform even the simplest tasks, like mapping a username to a uid, etc. pp. -- so starting it without the "/usr/libexec/StartupItemContext" in the background is out of the question. Now -with all that said- here's my question: What has changed with regards to "processual context" between 2.0.15 and 2.1.10 when the "imap" process is spawned/exec'd? Any environmental cleanups, closing of unknown fds, deletion/modification of environment variables, process-group-handlers, etc.? It appears, that the imap process no longer "inherits" the StartupItemContext from the main process, so some change between 2.0.15 and 2.1.10 must have broken it ... Any help is highly appreciated - Clemens PS: I google'd around a lot and searched the mailing-lists, of course. I only found a post of someone who ran into the same/similar problem dating back to Feb 21st 2012 under the subject "dovecot freezes when trying to get mail from maildir with mail", but it was quickly dismissed without ever getting resolved and that was that. PS2: I intentionally didn't include any configs with this mail as they seem to be irrelevant, but of course I can generate the necessary output if needed.

[Dovecot] Plugin "lazy_expunge" and subfolder
by Andreas Kossack 28 Sep '12

28 Sep '12

Hi Timo, hi all, we want to use the "lazy_expunge" plugin (from dovecot 2.1.10) and had configured it in a test environemnt like described in "http://wiki2.dovecot.org/Plugins/Lazyexpunge" (1 namespace) There are some subfolders from "INBOX" (like "INBOX/SPAM") in a "maildir++" configuration. All actions on first level directories ".INBOX", ."Sent" or ".Archives" are working as expected. If there is an expunge activity on e.g. ".INBOX.SPAM" directory we get an error message in dovecot log: Sep 26 12:27:55 imap(testuser): Error: lazy_expunge: Couldn't open expunge mailbox: Character not allowed in mailbox name: '.' What can we do or change to make it work? -- Best regards A.

[Dovecot] sieve vacation
by Bob Miller 27 Sep '12

27 Sep '12

Hello, I set up pigeonhole on a server and am using roundcube's sieverules to create a set of rules. When using the vacation feature, I can see in the logs that dovecot is sending the vacation response, but the recipient never receives it. What method does dovecot use to send the response? Does it use the sendmail binary, does it use the mail command, does it connect to some smtp server somewhere, does it use qmail-inject if it finds it? I find no evidence it is using any of these methods on my server, but I am not sure if one of these methods is failing or if there is some place else I should be looking for the missing vacation response... Thank you for any suggestions... -- Computerisms Bob Miller 867-334-7117 / 867 633 3760 http://computerisms.ca

[Dovecot] with mbox format doveadm ignores subfolders of inbox
by Jürgen Obermann 27 Sep '12

27 Sep '12

Hello. After we switched the format from mbox to mdbox on our dovecot (version 2.1.9) servers last week, some of our users were missing the subfolders of their inboxes. So far we thought that with the mbox format it is not possible to have mail folders containing both messages and subfolders. Now we know that there is one exception from this rule: the inbox. With mbox format dovecot supports subfolders of the inbox, and a few of our users actually detected and used this feature! Internally the messages are stored in /var/mail/user or in a file named 'inbox' and the subfolders are in the directory 'INBOX'. (The OS is case sensitiv.) The problem was that doveadm and dsync do not support subfolders of the inbox and therefore these folders did not get synchronized from our old mbox server to the new mdbox dovecot server. The command doveadm -o mail_location=mbox:~user123/Mail mailbox list -u user123 '*' did not show any subfolder of INBOX, whereas the the following with a wrong mail_location showed that there are subfolders of INBOX doveadm -o mail_location=mbox:~user123 mailbox list -u user123 '*' Finally we could import the missing subfolders one after one in the mdbox server with commands like this: doveadm import -u user123 mbox:~user123/Mail "" mailbox INBOX/subfolder all It would be nice if doveadm could be changed to not overlook subfolders of the inbox with mbox format.

[Dovecot] Changing Quota downward for special Mailboxes? (2.1.6)
by Jost Krieger 27 Sep '12

27 Sep '12

It seems there is no way to correct te quota limit downward for some mailboxes, like: quota_rule9 = UCE-TMP:storage=-10%% The idea is to not eat up the users storage with spam, so that spam stays in the queue (for some time) while real mail gets delivered. There *is* a line } else if (*value != '-' && relative_rule) { in quota.c, but nothing else handles it, starting with quota_rule_parse_percentage.

[Dovecot] 76Gb to 146Gb
by Spyros Tsiolis 26 Sep '12

26 Sep '12

Hello all, I have a DL360 G4 1U server that does a wonderfull job with dovecot horde, Xmail and OpenLDAP for a company and serving about 40 acouunts. The machine is wonderful. I am very happy with it. However, I am running out of disk space. It has two times 76Gb Drives in RAID1 (disk mirroring) and the capacity has reached 82%. I am starting of getting nervous. Does anyone know of a painless way to migrate the entire contents directly to another pair of 146Gb SCSI RAID1 disks ? I thought of downtime and using clonezilla, but my last experience with it was questionable. I remember having problems declaring disk re-sizing from the smaller capacity drives to the larger ones.

[Dovecot] second dovecot imap server
by Spyros Tsiolis 26 Sep '12

26 Sep '12

Hello again all, I would like to thank everyone for rushing to help me with the dovecot migration issue. I am , currently, reading and studying what has been said by all the good and kind people who responded to this list. OK, on the same issue,I thought of adding a totally new server with dovecot acting as a secondary/backup server for the mail servicing. Would that be possible ? What if I manage to make it work; Can I retire the old(er) server ? I would think that this is more on-topic than my last post. If I am out of line again, please respond in private. Thank you all! spyros ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis

I have a user who occasionally reads, then deletes emails using his phone, on his and others email accounts, causing emails deleted on mail server, then he says 'oops, can you recover emails I've deleted?' what's the best way to duplicate all emails to duplicate accounts ? backup folders ? so, next time he deletes emails they can be 'recovered' on the server ? I was thinking along the lines of duplicating ALL emails...? any tips and pointers appreciated -- Voytek

I'm going to bring it back on topic. To recap the issue: 1. 73GB volume, ~82% full. Volume contains OS, spool, and mailboxes 2. Two 146GB drives on hand that are impossible to employ in either a live or offline migration due to hardware limitations--drive slots (0.82*73GB=60GB)-5GB(OS)= ~55GB/40= ~1.375GB/user mailbox (This math assumes the box has already been scoured and things like source files and other temporary stuff has already been removed, along with anything and everything not necessary to the primary functions of this box) 1.375GB/user suggests these users seem to horde old emails, or simply don't keep their mailboxes tidy. Normally I'd guess that a lot of space in a situation like this is taken up by full text search indexes, but you don't appear to have these enabled. I notice in your 'dovecot -n' output that you are already employing zlib, but to what degree is currently unknown to the list. Are you compressing maildirs with a nightly script? If not, and you're compressing on an ad hoc basis, realtime compression during write could save you quite a bit of additional space, extending the operating life of your current drives. Of course a simple request to your users to clean up their mailboxes would surely help as well, if that's a possibility--some users would flog one for making such a suggestion. If you're not fully taking advantage of compression currently, you may want to consider upgrading to Dovecot 2.x which allows transparent compression to dbox and maildir storage. You may want to migrate to mdbox message store format while still using zlib, and enable single instance attachment storage (SIS). As the name suggests, SIS saves an attachment only once, regardless how many user emails in which it exists. See: http://wiki2.dovecot.org/Plugins/Zlib I'd point you to the docs for SIS but I'm unable to find them in the Wiki. Surely someone else can provide the settings and/or update the wiki. -- Stan

[Dovecot] Can`t get over 1024 processes on FreeBSD - possible bug?
by Tomáš Randa 24 Sep '12

24 Sep '12

Hello, I still cannot get dovecot running with more then 1000 processes, but hard limit is 8192 per user in box. I tried everything, including modifying startup script of dovecot to set ulimit -u 8192. Could it be some dovecot bug or dovecot<>freebsd bug? I also tried to set client_limit=2 in imap service to spawn more imap clients in one process, but still I am over 1000 processes with kernel message: maxproc limit exceeded by uid 89 Could anybody help?

[Dovecot] Traffic Accounting
by M. Naumann 24 Sep '12

24 Sep '12

Hi, I'm trying to find out how to do traffic accounting with Dovecot 2.x, preferrably v2.0.9, preferrably on CentOS 6. I've previously asked on IRC, but there was little feedback, and my understanding is now this list is the preferred media for such inquiries. If I recall correctly, some weeks ago I was told that traffic accounting is not officially supported on Dovecot 2, but that there could still be ways to get it to work, but no details were provided. I can think of the following approaches: * rawlog, preferrably piped (if that's possible?) into something like wc to prevent privacy issues and to reduce the I/O overhead * maildrop filtering in front of dovecot LDA (for mail inbound to mail storage) * sieve filtering Unfortunately I have little experience with either so far, so it's hard to make a good choice. I would appreciate hints on these approaches, and on any other approaches you can think of, as well as any related documentation / how-to you could point me to. While I'm subscribed to the list (for mail authentication purposes), I've disabled receiving any e-mail form the list, so please CC me on any replies. Thanks in advance, Moritz

Hi Testing dsync, things go wrong: doveadm sync -u user remote:root@mail2.example.net dsync-local(user): Error: Mailboxes don't have unique GUIDs: 72e3be2c6f203b50883c000044af56a8 is shared by RT and RT_72e3be2c6f203b50883c000044af56a8 Obviously RT_72e3be2c6f203b50883c000044af56a8 is an outdated copy of RT But .mailboxlist does not list that mailbox. Is there a trick to make sure dsync only use valid mailboxes? I have this in dovecot.conf mail_location = mbox:~/mail:INBOX=/var/mail/%u:INDEX=/mail/indexes/%u:SUBSCRIPTI ONS=../.mailboxlist Another problem, that may or may not be related: dsync-local(user): Error: Next message unexpectedly corrupted in mbox file /home/user/mail/RT at 60298748 dsync-local(user): Error: Failed to sync mailbox RT: Timeout while waiting for lock dsync-local(user): Error: Next message unexpectedly corrupted in mbox file /home/user/mail/RT at 63587421 dsync-local(user): Error: Failed to sync mailbox RT: Mailbox GUIDs are not permanent without index files I also get this: dsync-local(user): Error: Failed to sync mailbox RT: Mailbox GUIDs are not permanent without index files dsync-local(user): Error: proxy client timed out (waiting for MSG-GET message from remote) And this: dsync-local(user): Error: read() from worker server failed: EOF And generally speaking ,how good is dsync? is it usabel in production?

[Dovecot] Sieve as mail client?
by Tom Horsley 23 Sep '12

23 Sep '12

A slightly off topic question, but maybe someone here has seen something like this: I want a program that operates entirely on the client side of an IMAP server, and implements the sieve filtering language by doing the necessary client side operations to move mail on the IMAP server, expunge mail, etc. It would also act as a proxy between my real mail client and the IMAP server so I'd never see any mail that hasn't been filtered first. The benefits are obvious: I could finally get sieve filtering on my stupid corporate exchange mail server :-).

[Dovecot] Update: Hanging IMAP sessions on Mac OS X with dovecot 2.1.10 - worked fine with 2.0.15 (and 2.0.21)
by Clemens Schrimpe 22 Sep '12

22 Sep '12

Update: I tried with 2.0.21 and this also works just fine. So it must be something which came in with 2.1.x PS: Where is the documentaion for 2.1.x - i.e. for all the nice additions Timo made? The Website "only" has 2.0.x, as far as I can tell? (might be wrong here - hadn't touched the whole thing for a while, as my "civil life" had occupied me :-) Greetings, Clemens

[Dovecot] Dovecot 1.2.11 panic in mail-transaction-log-view?

I'm seeing this periodically in my logs for a specific user (followed by a backtrace which I've deleted from this post): Panic: file dovecot-1.2.11/src/lib-index/mail-transaction-log-view.c: line 290 (mail_transaction_log_view_set): assertion failed: (min_file_seq != max_file_seq || max_file_seq != view->head->hdr.file_seq || max_file_offset != (uoff_t)-1 || min_file_offset <= view->head->sync_offset) Is there something I can do to work around this problem for the user, or is this something new and I need to follow the instructions at http://dovecot.org/bugreport.html to send in a bug report?

[Dovecot] thunderbird does not copy a tree-structure to dovecot imap
by Anton 22 Sep '12

22 Sep '12

Hi, running in problems with KMail I decided to switch to dovecot-imap & thunderbird on my kubuntu 12.04 64 bit (so I can read my imap-folder-mails with KMail again if it gets more stable) What I did: - I wrote a python script to convert my KMail mails folder to a thunderbird mailfolder (directory tree containing mbox files and *.sbd folders) - I created a fake pop mail account in thunderbird and imported the whole mail-structure (i just copied it) - I create a local imap account ( so I have a ~/Maildir dovecot folder in my user dir) - In /etc/dovecot: 1. /etc/dovecot/10-mail.conf (line 10) I set: mail_location = maildir:~/Maildir:LAYOUT=fs 2. /etc/dovecot/20-imap.conf (line 57) I set: imap_client_workarounds = tb-extra-mailbox-sep Now I want to copy the whole mailstructure from my imported fake pop mailfolder to the dovecot imap folder. What happens: Lets say my source structure is mailfolder1 + mail1 + mail2 + subMailFolder2 + mail1-in-subMailFolder2 + mail2-in-subMailFolder2 + subSubMailFolder3 + mail1-in-subMailFolder3 + mail2-in-subMailFolder3 I thunderbird (version 15) I drag and drop my mailFolder1 to the imap folder and I get: mailfolder1 + mail1 + mail2 + subMailFolder2 + subSubMailFolder3 as you See only the mails of the *TOP* folder are copied. All subfolders are created but they contain NO MAILS. Did somebody experience the same problem??? Otherwise I will write a python script to do that (I dont hope to need to write a mailclient in python ;-) ) Any hint is greatly welcome. Anton
