[Dovecot] LAYOUT=fs vs LAYOUT=maildir++ and quota
by Ezequiel Alfíe 16 Jun '09

16 Jun '09

Hi everyone. I'm confused about LAYOUT=fs... Does using LAYOUT=fs breaks maildir++ quota, if I use this quota scheme? What are the advantages anyway of using LAYOUT=fs vs LAYOUT=maildir++ ? (it's not important in my case if users can't create folders with dots '.') Thanks in advance, Ezequiel

[Dovecot] shared folders in v1.2 with one uid per user
by Ezequiel Alfíe 16 Jun '09

16 Jun '09

Hello everyone. I'm new to dovecot and I'm setting up a server for one domain only. I have not yet decided whether I will be using one uid per user or one uid for all of them. What are the steps for correctly setting up shared folders with acls if I choose one uid per user? What advantages or disadvantages has setting one uid for all users vs one uid per user, considering I wish to setup shared folders (including security, performance, etc) ? Thanks in advance, Ezequiel

[Dovecot] Multiple mail locations for a single user
by Ross Burton 16 Jun '09

16 Jun '09

Hi, I use offlineimap to cache my remote IMAP mail for my multiple accounts (personal, work, etc) to several maildirs locally. At the moment in my mail client I'm using Dovecot to access one of the maildirs via IMAP, and then direct maildir access for the others. This is suboptimal however because my clients direct maildir support isn't great. Is there any way to let me access all three maildirs through dovecot? I'm guessing that I can do this with namespaces but I'm not sure. Any suggestions and pointers? Cheers, Ross -- Ross Burton mail: ross(a)burtonini.com jabber: ross(a)burtonini.com www: http://burtonini.com

[Dovecot] Archiving feature
by Romer Ventura 16 Jun '09

16 Jun '09

It would be nice to have some sort of archiving feature on which dovecot can save emails older than N+1 months to either a remote Dovecot server with MySQL as storage or a separate instance of Dovecot running on the same server but storing the emails in MySQL Is any of this possible now, or in the works...?

[Dovecot] IMP reading entire mailbox
by Chris O'Regan 16 Jun '09

16 Jun '09

We have been noticing a constant hum of traffic between our IMAP server (Dovecot v1.1.14) and our filers over the past several days. I have narrowed it down to one particular user who has been logged in to IMP/Horde since the problem began (he hadn't logged since we upgraded to Dovecot a week before). IMP is periodically checking this user's mail every five minutes. Each time it does, the his entire mailbox is being read. I initially thought it might be an indexing problem since I am also seeing messages such as this in the logs: Corrupted index cache file /local/data/dovecot/indexes/mail/X/XXXXXXXX/.imap/delivery.log/dovecot.index.cache: Broken MIME parts for mail UID 30880 But the in/out bytes being logged by Dovecot indicate that the entire contents of his mailbox are being sent to the client. That is, this user has a particularly large mailbox (~500M) and about 500M are being sent to IMP every five minutes. (Actually, what is the meaning of the above message? He's the only user logging it.) The user does have some filters defined in IMP, but I can't imagine that it would try to apply them to the entire mailbox each time it is accessed. Surely it would only apply the filters to new messages, right? But I can't think of any other reason why we would be seeing this behaviour, and only for this user. I have not yet contacted the user as I need something to tell him other than "you're a bandwidth hog". I think the next step is to ask him to disable his filters, but I would prefer not shooting in the dark. This user alone is adding about 50Mbps of bandwidth; between the time we upgraded to Dovecot (from uw-imap) and he logged in, we were witnessing a huge drop in traffic. He's ruining our graphs! ;-) Seriously, if anyone has some ideas, please let me know.

[Dovecot] Dovecot v1.2.rc5 dbox file permissions
by Pascal Volk 16 Jun '09

16 Jun '09

Hi Timo, I've just setup Dovecot v1.2.rc5 and switched the mailbox format of one account to dbox. Therefor I've created an empty directory, called dbox, with access mode 0700, like the user's home directory. After the IMAP login with Thunderbird some dboxes was created. All permissions were set fine (0700 / 0600), except the permissions for the files: * ~/dbox/mailboxes/$FOLDERNAME/dbox-Mails/dbox.index * ~/dbox/mailboxes/$FOLDERNAME/dbox-Mails/dovecot.index.log Those files have the access mode 0666.

[Dovecot] mixing dovecot and non-dovecot access to mail
by Michal Szymanski 16 Jun '09

16 Jun '09

Hello, I have recently installed Mailscanner/postfix for the mail server and dovecot for (mainly remote) access to email (via T'bird etc. and/or Webmail). Most users still use text mail clients (mutt, pine, some still old elm) while in the office. These clients access mail (both incoming at /var/mail/ and users' private folders in ~/Mail) directly. I wonder whether this mixing of dovecot and non-dovecot access can make any problems, provide, of course, that the users are not using both ways at the same time. AFAIK dovecot makes some indexing. Will it not be confused if the folder is changed and de-sync-ed with the index? regards, Michal. -- Michal Szymanski (msz at astrouw dot edu dot pl) Warsaw University Observatory, Warszawa, POLAND -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Dovecot] dovecot-antispam plugin and "Failed to call dspam" message

Hi, I had this working until I recently upgraded Dovecot, and now I'm getting a message back from Thunderbird of "Failed to call dspam." when I attempt to move a message into one of the designated spam folders.

[Dovecot] dovecot-antispam and permissions
by Tom Hendrikx 14 Jun '09

14 Jun '09

hi list, I'm having trouble with a new setup. My server is running postfix (2.5.5), dovecot (1.1.7), dspam (3.8.0). These all seems to work with eachother. When I add dovecot-antispam in the mix, the following problem occurs: New mail arrives, postfix hands the mail to dspam using a content_filter, and dspam clasifies the mail, running as the dspam user. Dspam writes its data away in a sqlite database. Mail then gets reinjected into postfix and delivered to the system user by deliver. When I manually classify a mail using dovecot-antispam, dovecot runs dspam classification as the system user. This gives the error "failed to call dspam" in my client, and the message "dspam[20203]: query error: attempt to write a readonly database: see sql.errors for more details". Since the mentioned sql.errors is owned by the system user and not by the "dspam" user, it seems that the re-classification proces is run as that user, so he has no write access to the sqlite db, which is owned by dspam:dspam. I could fix this by manually changing group ownership to the database, but maybe there is a more generic way to solve this? -- Regards, Tom

[Dovecot] Couldn't open INBOX: Timeout while waiting for lock
by Eric Sammons 12 Jun '09

12 Jun '09

Hi, So I've been through google and the dovecot source and have not yet found a reasonable explanation for the 'Timeout while waiting for lock' error. My customer's configuration is utilizes mbox with the following mbox configs. [snip] pop3_lock_session = yes mbox_read_locks = fcntl mbox_write_locks = fcntl mbox_lock_timeout = 300 [/snip] I see from the source that this error can occur in one of two places: mbox_lock_dotlock() mbox_update_locking() Given my customer is using fcntl locking I automatically assume that it is the later where they are hitting the error. While I see in the source these errors are Temporary Errors; I do wonder what is the specific cause and what should we be looking at to address the errors. One thing we have noticed is that the errors do not occur regulararly. For exapmle, there were no such errors reported on June 9 or June 10; however on June 11 and 12 the errors started to appear. Any direction / pointers are greatly appreciated. Thank you! -- Eric L. Sammons, RHCE

[Dovecot] Dovecot as a (quota) policy server for Postfix
by Wolfram Schlich 12 Jun '09

12 Jun '09

Hi guys, I'm currently experimenting with Postfix, Dovecot and OpenLDAP to setup a mail server hosting virtual users. The standard stuff works fine so far. The only thing that doesn't work as I'd like it to do is Quota. Currently, Dovecot handles/enforces quota through the deliver LDA. When Postfix tries to deliver a mail to a mailbox that is over quota, the deliver LDA bounces the mail back to the sender. I don't like that. I'd rather prefer Postfix to reject the mail right after receiving the '.' DATA termination line and having checked whether the users quota is or would be exceeded. This could work by writing a small Postfix policy server/daemon that does exactly that Dovecot does: - get the user quota limit from userdb (from LDAP in my case) - get the user quota used (from maildirsize in my case) _ check whether the current mail size + quota used exceed the quota limit and if true, reject the mail Of course this would only work for mails going to a single local recipient address, but most of the time, that's just the case. Now I can re-implement that part of functionality from Dovecot in Perl and write such a small policy daemon that does exactly fit my setup (LDAP + maildirsize). There's one thing I'd like much better, though: What about extending Dovecot by a small policy server module for Postfix? Dovecot already has all the code to do the "over quota" checks and supports a great number of combinations for quota limit and used quota storage. My Postfix instance already kinda depends on a running Dovecot due to Dovecot-SASL for SMTP-Authentication and Dovecot-deliver for mail delivery, so it wouldn't introduce a completely new dependency either. Timo (and all others), what do you think about such a Postfix policy server implemented as a part of Dovecot? -- Regards, Wolfram Schlich <wschlich(a)gentoo.org> Gentoo Linux * http://dev.gentoo.org/~wschlich/

[Dovecot] Dovecot fails to deliver in mail clients

11 Jun '09

Morning I am new to linux and have configured a Postfix + Dovecot Mail server on my SUSE Linux Server 10 SP2 Machine. Postfix works fine I assume as mail gets delivered to user's mailbox or directories. But when I configure a mail client to download mail from the server it finds no mail. When I check the user's mailbox using Webmin mail is delivered. I have also tried to telnet to the server when I do I am able to log in with user's credentials but when I type the list or stat command telnet says there is no mail 0.0Kb. I have tried everything, mail gets delivered to inboxes but telnet and mail clients don't get mail. Please let me know what I am doing wrong Zwelabantu Ngwenya

[Dovecot] unable to send mails via postfix/dovecot SASL
by Michal Szymanski 11 Jun '09

11 Jun '09

Hello, I have a freshly setup postfix/dovecot mail server (after a server upgrade I decided to change my sendmail/popper conf to something more modern :) It mostly works, there is no problem in sending/receiving mails in local network, both using text clients like mutt or pine dealing with the incoming/outcoming mail directly. Also dovecot works fine with SSL authentication from the outside world (home computers etc) but only for reading the mail. I have been struggling for several days already to get postfix/dovecot/SSL trio to work for sending (relaying) mail from the home computers (but also from local network) via my server to the final recipients, using authenticated connections. I followed http://wiki.dovecot.org/HowTo/PostfixAndDovecotSASL hints for the configuration of postfix and dovecot (see output of dovecot -n and postconf -n commands below). I also uncommented "smtps" line in /etc/postfix/master.cf file (otherwise postfix was refusing any connections to secure SMTP port). For a while, I uncommented also "submission" line there but to no success either. Now when I try to send a mail from my home PC, using Thuinderbird 2.0.0.21, with SSL connection configured for outgoing smtp server (port 465), using username/password, it shows "Connected to server..." message but after a minute or so, it fails saying that the connection to SMTP server failed. The server log shows: 11:51:24 sirius postfix/smtpd[15126]: connect from my_home_pc_name/ip Jun 11 11:52:25 sirius postfix/smtpd[15126]: lost connection after UNKNOWN from from my_home_pc_name/ip Jun 11 11:52:25 sirius postfix/smtpd[15126]: disconnect from my_home_pc_name/ip There are no dovecot-related messages in the log regarding such an attempt. I am not sure whether this is dovecot or postfix problem but, being no expert on either of those, I am asking help to resolve this annoying problem. with best regards, Michal. -------------- dovecon -n -------------------------- # 1.0.7: /etc/dovecot.conf ssl_cert_file: /etc/pki/dovecot/certs/sirius.pem ssl_key_file: /etc/pki/dovecot/private/sirius.key login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_location: mbox:~/Mail:INBOX=/var/spool/mail/%u mmap_disable: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh imap_client_workarounds(pop3): outlook-idle pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login verbose: yes passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix ----------------- postconf -n ---------------------------- alias_database = hash:/etc/mail/aliases alias_maps = hash:/etc/mail/aliases broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix debug_peer_level = 2 header_checks = regexp:/etc/postfix/header_checks html_directory = no inet_interfaces = all mail_owner = postfix mailbox_command = /usr/bin/procmail mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man masquerade_domains = astrouw.edu.pl mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain, mail.$mydomain, www.$mydomain, ftp.$mydomain, /etc/mail/local-host-names myhostname = sirius.astrouw.edu.pl newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES sample_directory = /usr/share/doc/postfix-2.3.3/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtp_generic_maps = hash:/etc/postfix/generic smtpd_recipient_restrictions = check_recipient_access hash:/etc/postfix/access, permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, reject_unlisted_recipient smtpd_sasl_auth_enable = yes smtpd_sasl_path = private/auth smtpd_sasl_security_options = noanonymous smtpd_sasl_type = dovecot unknown_local_recipient_reject_code = 550 --------------------------------------------------------------- -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Dovecot] Quota over NFS with inode limit
by Patrick Domack 11 Jun '09

11 Jun '09

I tried searching this list, but couldn't find anything related to inode limits except for linux quotas. I wanted to add sieve support for our users, so was attempting to get our email system to use dovecot's deliver lda to handle email, instead of postfix's virtual lda, using maildir mailstore. When I did this, I noticed that emails would get stuck in the queue if a user was over quota, this got fixed when I added in quota support, and set it up to check it using the line: quota = fs:User quota:user:inode_per_mail Now if a user excedes disk space via quota, it's bounced with a message. But if a user excedes their inode quota, it's still tempfail and hangs in the queue till it expires. I just wanted to know if anyone knows about this issue, if I made a stupid mistake or anything else, before I go digging into the source.

Hi all, Dovecot with the "new Sieve" works fine, but 1 - how to have a global script AND 1 script per virtual maibox ? 2 - how to allow a user to change this script (from Thunderbird or Outlook) Thanks JM

[Dovecot] record points outside file error with dovecot revision 9116:9ae55b68cf61
by Jonathan Siegle 11 Jun '09

11 Jun '09

I use mbox with mbox-snarf plugin. I get errors like: dovecot: IMAP(testuser): Corrupted index cache file /full/path/ dovecot.index.cache: record points outside file The errors can be in either folders or INBOX. I put some syslog statements in src/lib-index/mail-cache-lookup.c to help understand this. if (offset + sizeof(*rec) > cache->mmap_length) { mail_cache_set_corrupted(cache, "record points outside file"); syslog(LOG_DEBUG,"mail_cache_get_record rec->size is %d ", rec->size); syslog(LOG_DEBUG,"cache->mmap_length is %d ", cache- >mmap_length); syslog(LOG_DEBUG,"offset is %d ", offset); return -1; } syslog: mail_cache_get_record rec->size is 268595472 syslog: cache->mmap_length is 4096 syslog: offset is 1630760037 Oh I forgot to print off sizeof(*rec). Would that help? Thanks, Jonathan

[Dovecot] SELinux
by Kenneth Porter 10 Jun '09

10 Jun '09

I've temporarily got SELinux set to permissive mode on a fresh install on CentOS 5. It was blocking Dovecot's access to ~/mail because the files were labeled file_t. What's the correct way to label these?

But really, all this leads is that admin has to detect the dovecot termination and simply go and restart it manually -- after some bad thoughts. I think that a config option to restart silently (or simply kill all connected imap/pop3 instances) would be quite reasonable. Basically it is the only thing I don't like in Dovecot... and was even planning to hack the time check out of the code =)) Best wishes Eugene

[Dovecot] Resync quota to mysql script
by Oli Schacher 09 Jun '09

09 Jun '09

I changed some quota options in my dovecot config (eg. excluded folders) but afaik this only affects new mail and there is no magic command to recalculate the quota (or is there?). So I wrote this little python script to do this, maybe someone finds it useful. It can output the sql statements (dovecot 1.0/1.1 and 1.2 format) or just print out quota usage to console.

[Dovecot] Managesieve
by Thomas E. Deutsch 09 Jun '09

09 Jun '09

Hi I've a problem. I've built a new mailserver for our company based on dovecot (1.1.15). At the same time, our company's name has changed. The old mail addresses are forwarded to the new addresses. But I've a problem with sieve. It looks like the sieve filters are only working for the new addresses. But due to the change of the name was not long ago, most of the mails are still sent to the old addresses. What can I do to get filters also working for the old addresses? Configuration of managesieve: protocol managesieve { listen = *:2000 login_executable = /usr/lib/dovecot/managesieve-login mail_executable = /usr/lib/dovecot/managesieve sieve = /home/vmail/%Ld/%Ln/sieve/dovecot.sieve sieve_storage = /home/vmail/%Ld/%Ln/sieve managesieve_implementation_string = Cyrus timsieved v2.2.13 # mail_debug=yes } Regards, Thomas

[Dovecot] Login processes in Dovecot
by Scott Haneda 08 Jun '09

08 Jun '09

I will be deploying Dovecot on OS X shortly. I am looking for clarification on the limits imposed by OS X and sysctl [kern.maxproc]. I understand that it is defaulting to 532, but can be raised to 2500. I believe the OS uses around 100 or so, plus I will have other processes and shells at times. Does Dovecot use one process per user logged in? I find Apple Mail uses about 4 IMAP connections per account. I am not sure that my current number of mail users would be able to be supported on OS X even if I bump up to 2500. Does Dovecot use one process per user logged in differently based on IMAP versus POP? Perhaps this is something that can also be changed in Dovecot, if so, can someone point me to the docs about it, or explain the downsides of going against default behavior. If this is the case, what are my options? Does OS X server have a higher limit in their kernel, or is this across the board? Is it even possible to compile a kernel for OS X with this change, or does that generally mess things up pretty bad? FreeBSD and Solaris seem to have much higher limits, and certainly a much more approachable way of upping those limits. Does anyone know why OS X chose to set these so low, especially given that they do sell server based hardware with a server based OS. Thanks. -- Scott * If you contact me off list replace talklists@ with scott@ *

[Dovecot] Mailbox isn't a valid mbox file

Getting "Mailbox isn't a valid mbox file" on 1.2rc2 after transferring mail from an ancient 0.99.13 system. The first line of the file looks ok. Curiously, it's one of my archival folders of this list. Here's the first header from the top of the file: >From tss at iki.fi Sat May 1 21:48:17 2004 From: tss at iki.fi (Timo Sirainen) Date: Sat May 1 21:54:18 2004 Subject: [Dovecot] 1.0-test2 released Message-ID: <1083437297.21296.19.camel@hurina> X-IMAPbase: 1085322222 20128 Status: RO X-UID: 14065 Content-Length: 226989 X-Keywords: It would be nice if the code that verified the mailbox format would log details about what it disliked.

[Dovecot] General performance of RC5
by Joan 08 Jun '09

08 Jun '09

Hi all, Switiching to RC5, there is a visible decrease in performance to access via IMAP large accounts (>1G) with mutiple mailboxes per accounts. In RC4, there was no delay visible by a human when accessing locally. Now it takes up to 4 or 5 secs. (running on OpenSuse, mysql 5.1.35 for auth, dbox as back end) Anybody experienced also this ? Thanks Joan

[Dovecot] Multiple Dovecot instances over single mail store
by Zohan 06 Jun '09

06 Jun '09

Hi, I need to run two Dovecot instances with totally different authentication configs: first - passwordless, based on client SSL certificate; and second - regular password based (LDAP, passwd etc.). (As far as I know this cannot be achieved with single Dovecot instance; if I'm mistaken, please correct me). My intention is to give clients dual access to their mailboxes: some do own a SSL cert, others do not. I want to know whether it is possible at all. If possible, how do we implement proper concurrent access (locking, etc.) between the two instances to a single maildir-based store? I guess this should be possible since I know Dovecot can operate NFS-backed mail stores, e.g. in a load-balancing cluster setup. Second, is it OK to run the second instance in the same OS (we use Linux)? or chroot'ed or even virtualized solution will work better? Thank you! Zohan

[Dovecot] sieve/dovecot folder separator inconsistency
by Daniel Mayer 05 Jun '09

05 Jun '09

Hi, I'm running dovecot 1.0.15 and ran recently into a problem with the folder separators when using sieve scripts. The server is set to use a slash as a folder separator for all namespaces and announces this correctly when issuing the NAMESPACE command. We are using Ingo (http://www.horde.org/ingo/) of the horde framework to manage our sieve scripts. It creates the folder name / folder path to be used in the sieve scripts based on the result of the NAMESPACE given by the IMAP Server. It therefore created the path separated by slashes ("/"). According to my tests, the delivery agent along with sieve expects the folders to be separated by dots (".") instead of slashes. Is this a correct observation or can this be set using a parameter or something similar? The result of this otherwise inconsistent behavior is that a client who sticks to the provided namespace creates a folder path which cannot be understood by the deliver process. Please let me know if you need any additional information. Thanks, Daniel

[Dovecot] Dovecot under brute force attack - nice attacker
by henry ritzlmayr 05 Jun '09

05 Jun '09

Hi List, optimizing the configuration on one of our servers (which was hit by a brute force attack on dovecot) showed an odd behavior. Dovecot Version 1.0.7 (CentOS 5.2) The short story: On one of our servers an attacker did a brute force attack on dovecot (pop3). Since the attacker closed and reopened the connection after every user/password combination the logs showed many lines like this: dovecot: pop3-login: Aborted login: user=<test>,...... The problem: If the attacker wouldn't have closed and reopened the connection no log would have been generated and he/she would have endless tries. Not even an iptables/hashlimit or fail2ban would have kicked in. How to reproduce: telnet dovecot-server pop3 user test pass test1 user test pass test2 ... QUIT ->Only the last try gets logged. If I enable auth_verbose every attempt gets logged, but if I read the docs correctly this option should only be used for figuring out why authentication isn't working. Question: Is there any way to close the connection after the first wrong user/pass combination. So an attacker would be forced to reopen it? This would be perfect since an easy iptables/hashlimit would avoid such a brute force attack. Any other Ideas? Henry

http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc5.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc5.tar.gz.sig Some small fixes mainly. I guess I'll still have to release rc6 and rc7 after all. I've been a bit busy with v2.0 changes recently. BTW. I'm leaving tomorrow to San Francisco and I'm going to check out what's happening in Apple WWDC next week. * auth_cache_negative_ttl is now used also for password mismatches (currently only with plaintext authentication mechanisms). + Added support for EXTERNAL SASL mechanism. + FETCH X-SAVEDATE can now be used to get messages' save timestamps + deliver_log_format: %s is now in UTF8 - If message body started with a space, some operations could have assert-crashed. - Fixed using LDAP support as a plugin - Fixes to virtual mailboxes.

Under load, we are experiencing the following errors: Jun 4 18:30:59 ug1s02-zone1 dovecot: [ID 107833 mail.error] auth(default): ldap(0202934816(a)ug.smilecoms.com,10.31.3.13): ldap_search() failed (filter (uid=0202934816(a)ug.smilecoms.com)) Server is busy We are authenticating against sun directory server yet see no errors in the directory server and it seems to be under low load. Any ideas if there is something on dovecot we should tune to erradicate this? We are running a web front end on top of dovecot and hence have a lot of login/logout happening as the user navigates around.

[Dovecot] imapmagicplus equivalent?
by Juergen Kreileder 04 Jun '09

04 Jun '09

Hi, is anything like Cyrus IMAP's imapmagicplus option available for Dovecot? If not, would it be possible to implement as a plugin? > imapmagicplus: 0 > Only list a restricted set of mailboxes via IMAP by using userid+namespace syntax as the authentication/authorization id. Using userid+ (with an empty namespace) will list only subscribed mailboxes. It's a quite useful option for clients that don't understand subscriptions. E.g., I don't want to see all of my folders on my iPhone, by using userid+ I can limit them to a useful set. Juergen

[Dovecot] Password environment variable - logging the password
by Donovan Craig 04 Jun '09

04 Jun '09

Hi, We¹re migrating to a Cpanel hosting system. Our passwords are currently stored in MD5. I looked at the post login scripting to be able to start storing the plain text passwords as people login temporarily so we can automate our migration. It seems that the password is not available in the post login environment variables. Is there any way we can get access to the plain text password upon login so we can insert this into our user table? Best regards, Donovan

[Dovecot] Some questions about deliver
by Axel Luttgens 04 Jun '09

04 Jun '09

While investigating Dovecot's deliver with Postfix, I encountered some behaviors making me wonder whether I really understand the purpose of that binary. So, if you allow... This is from Postfix' main.cf: mailbox_command = /usr/local/dovecot/libexec/dovecot/deliver -e -n This is my quick setup for Dovecot: # 1.2.rc4: /usr/local/etc/dovecot.conf # OS: Darwin 9.7.0 i386 protocols: pop3 ssl: no disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/dovecot-1.2.rc4/libexec/dovecot/pop3- login first_valid_uid: 2001 mail_location: mbox:~/_mailboxes:INBOX=~/_inbox/mailspool mbox_read_locks: flock mbox_write_locks: flock dotlock mail_executable: /usr/local/dovecot-1.2.rc4/libexec/dovecot/pop3 mail_plugin_dir: /usr/local/dovecot-1.2.rc4/lib/dovecot/pop3 pop3_lock_session: yes pop3_uidl_format: %08Xv%08Xu auth default: passdb: driver: pam args: * userdb: driver: passwd Here is an excerpt from mail.log: postfix/smtpd[4117]: connect from localhost[127.0.0.1] postfix/smtpd[4117]: 163E1CA2675: client=localhost[127.0.0.1] postfix/cleanup[4120]: 163E1CA2675: message-id=<27002A3F-AF44-410D-A500-368D04F5FA9A(a)almbp.local > postfix/qmgr[3232]: 163E1CA2675: from=<testuser(a)almbp.local>, size=2650, nrcpt=1 (queue active) dovecot[4129]: deliver(www): mail_location: mbox: mkdir(/Library/ WebServer/_mailboxes) failed: Permission denied (euid=70(_www) egid=70(_www) missing +w perm: /Library/WebServer) dovecot[4129]: deliver(www): Fatal: Namespace initialization failed postfix/local[4122]: 163E1CA2675: to=<www(a)almbp.local>, relay=local, delay=0.09, delays=0.02/0/0/0.07, dsn=4.3.0, status=deferred (temporary failure) postfix/smtpd[4117]: disconnect from localhost[127.0.0.1] 1. Shouldn't deliver honor the first_valid_uid setting? After all, if some user isn't allowed to login, is that user supposed to receive mail? 2. What exactly is the -e option supposed to do? User _www clearly isn't configured for receiving mail, but Postfix will nevertheless try to deliver the message until maximal_queue_lifetime has expired. From the log excerpt, it appears that Postfix has been led to consider a temporary failure; unless I'm wrong, that's because Postfix didn't receive neither a "D.S.N text" string nor an EX_* fatal return code. From deliver.c, it seems that many calls to i_fatal() are liable to be executed before the -e option is taken into account (through the local variable stderr_rejection). As a result, I'm wondering under which circumstances exactly deliver is liable to return EX_NOPERM, so that Postfix may consider a permanent failure and bounce the message. Note that the question may somehow be re-phrased as: when invoked without the -e option, under which circumstances will deliver send a rejection message? 3. Doesn't failure_exit_callback() in deliver.c tend to merge many (possibly dissimilar) errors into the single EX_TEMPFAIL one? And BTW, is that function guaranteed to be always called with an EX_* value? Seems to be the case, but... ;-) TIA for your patience, Axel

Hi all I am in the process of migrating Courier to Dovecot, am using courier-dovecot-migrate.pl<http://www.dovecot.org/tools/courier-dovecot-migrate.pl>it works fine. I want to migrate each user as they login using post-login script (As i have huge no of users). We are using NFS storage, users are authenticated using mysql, User home directories as passed using variable mail ( usign mysql query). I am trying to execute postlogin script which does the conversion but unable to pass the user home directories . --*/etc/dovecot.conf mail_executable = /usr/libexec/dovecot/postloginscript.sh %h ---* %h ---- for home directory. ---*postloginscript.sh #!/bin/sh /usr/libexec/dovecot/courier-dovecot-migrate.pl --quiet --to-dovecot --recursive --convert $1 # This is for pop3 exec /usr/libexec/dovecot/pop3 ----* When i pass %h as argument its creating "%h" directory and writing dovecot-uidlist and rest the files in %h directory. Its not interpreting the %h and not passing the home directory. Its just passing as it is. Hope i am clear in articulating my problem. Please help. -- Regards Ash

[Dovecot] 1.2.beta1: expire-tool and 'mail_location' setting
by e-frog 03 Jun '09

03 Jun '09

Hi Timo, Trying 1.2.beta1 with expire plugin currently: When I set mail_location = maildir:~/.maildir the expire plugin doesn't delete messages. #: expire-tool --test Info: auth input: system_user=foo Info: auth input: uid=1000 Info: auth input: gid=1000 Info: auth input: home=/home/foo Info: foo/Trash: no messages left I also noticed that above command creates a new but empty directory 'mail' in user's home dir. However using mail_location = maildir:~/Maildir and of course moving the messages to it works. #: expire-tool --test Info: auth input: system_user=foo Info: auth input: uid=1000 Info: auth input: gid=1000 Info: auth input: home=/home/foo Info: foo/Trash: seq=1 uid=4078: Expunge . .

Hello, is the expire plugin usable to delete mails with different settings for each individual user? If i view sample config at http://wiki.dovecot.org/Plugins/Expire it looks like expire-data are related to foldernames. Is it possible to let each user "activate" the expire-plugin for different folders with different settings? Thanks, Andre

http://dovecot.org/releases/1.1/dovecot-1.1.16.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.16.tar.gz.sig Fixes a couple of bugs in v1.1.15's changes. Hopefully the last v1.1 release before v1.2.0. - v1.1.15 could have crashed if mailbox-closing command was pipelined after a mailbox-accessing command. - v1.1.15's zlib plugin may have caused crashes when fetching INTERNALDATE. - Maildir: If messages had been deleted externally from new/ directory and mailbox was opened with EXAMINE, Dovecot didn't immediately notice that the messages were deleted. - If message body started with a space, some operations could have assert-crashed.

[Dovecot] recipient delimiter and lmtp
by John Fawcett 02 Jun '09

02 Jun '09

I read in the list archives about work in progress on an lmtp delivery agent.As a previous cyrus user where that was the preferred delivery method from postfix, this sounds interesting. I was wondering whether it will handle recipient delimiters. ie will it be able to map user+foo(a)example.com to user(a)example.com? I'm not interested in the delivery into folder stuff, just the plain delivery to inbox. thanks, John

[Dovecot] IMAP labeling sometimes not taken into account
by Olivier Cailloux 02 Jun '09

02 Jun '09

Dear Dovecot list, I recently switched from uw-imapd to dovecot to manage my huge mbox files (about 1 GB). I now observe a very strange behavior, difficult to reproduce reliably, which might be related to some misunderstanding on my part on how either dovecot works or imap labeling works. What I call "labeling" is the fact of marking some e-mail, in my e-mail client (currently Thunderbird), with a label, which can be chosen among five labels (plus the "no-label" case). Evolution also supports labeling. As far as I understood until a few days ago, when I put a label, say, number five, on an e-mail, a keyword "$Label5" is added on the "X-Keywords:" line of the corresponding e-mail in my mbox file. Removing the label simply removes the keyword on the same line. That is, at least, what happened with uw-imapd (not that I have seen that documented somewhere but this is what I observed). The label is thus stored on the e-mail server, not on the client hard disk, which is important for me as I extensively use that feature to sort e-mails, and need to access them from several different places (and find the same labels at the same places, naturally, whatever client I use). Since the change for dovecot, however, things are going strange. Sometimes the labels disappear for some reasons. Sometimes they stay there. And I can't reproduce the behavior, it just seems random. This is very annoying as it totally breaks my e-mail management. Currently there is something strange I can reproduce however, and if someone could explain me what is happening I guess it would be a good step towards a solution. I see a specific e-mail as being labeled in thunderbird, having label number five. I also tried with evolution, accessing the same imap folder, evolution also sees that e-mail as having a label number five. I tried running these clients from my imap server, and I tried thunderbird on a Windows box at home, and every clients agree: this e-mail has a "5" label. BUT when I open the mbox file directly on the imap server (using "less"), and scroll to that given e-mail, I see NO "X-Keywords: " line. How then can the e-mail clients know that this e-mail is labeled? Please note that this behavior does not happen with only one specific e-mail, but I take it as an example of what is strange. In fact I can see, especially at the end of the mbox file (thus the latest e-mails), that plenty of e-mails have either no "X-Keywords: " line or a line with "X-Keywords: " and nothing else, whereas they are seen as being labeled (and indeed I remember having labeled most of those through thunderbird). The former e-mails I checked in the m-box (for example, one month ago) all correctly have an X-Keywords line indicating "$Label5" or other appropriate labels. It seems like dovecot is keeping some track of labeled e-mails somewhere which is NOT in the mbox file, probably related to its indexing capabilities. But I don't know how that works and where these index files are stored, how to purge them and rebuild the index, and so on. Apparently these index files have remembered some e-mails as being labeled (which is good, because I indeed labeled them). But I'd like to know how that works to be able to better troubleshoot why sometimes the label disappear. Note that restarting dovecot does not change the label status of the e-mail, so the status must be stored somewhere on disk and not only in memory. Or is all these labeling stuff some unsupported, non-standard extension to IMAP that only uw-imapd supports? (I hope not because I find it very practical and I'd like to use it with dovecot as well!) Thank you for any help. (Technical informations follow.)

[Dovecot] Capability problems dovecot 2.0
by ja nein 01 Jun '09

01 Jun '09

Hi, I had some problems connecting TB 2.x with dovecot 2.0. TB2 complained about not being an IMAP4 server. TB 3 worked. It seems that dovecot 2.0 doesn't return capabilities when queried. Maybe some wrong config, thoug? Here are the debug logs from TB2 comparing dovecot 2.0 (not working) and dovecot 1.2 (working): Dovecot 2.0: NA:CreateNewLineFromSocket: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN AUTH=LOGIN AUTH=DIGEST-MD5 AUTH=CRAM-MD5] Dovecot ready.

[Dovecot] For the record: Postfix+Spamassassin+ClamAV+Dovecot
by James Butler 01 Jun '09

01 Jun '09

Postfix 2.5.5 SpamAssassin 3.2.5 (under Perl 5.10.0) ClamAV 0.95.1 Dovecot 1.2.rc2 works fine on Fedora 10. Installed Dovecot and ClamAV from source and everything else using yum. I'm using the ClamAV plugin for Spamassassin: http://wiki.apache.org/spamassassin/ClamAVPlugin I'm calling Spamassassin with: /etc/postfix/main.cf: mailbox_command = /usr/bin/spamc -f -e /usr/local/libexec/dovecot/deliver Postfix hands off to Spamassassin, which processes ALL mail (not just attachments) through the ClamAV plugin before parsing for spam, and then hands the whole mess off to Dovecot for 'deliver' to handle. How simple is that? Since ClamAV scanns all mail, it might be too processor-intensive for really large mail systems, but it is working great for our 120+ user system with lots of spam coming in. If you're using Procmail or some other preprocessor that can hand off to a pipe, then you could skip the plugin and pipe messages over a certain size (i.e. >1024) to clamd, instead. Enjoy! James

[Dovecot] Namespace delimiter...
by Lenthir 01 Jun '09

01 Jun '09

As RFC3501 (IMAP) say: 'A NIL hierarchy delimiter means that no hierarchy exists; the name is a "flat" name.' How to change delimiter to NIL? We have flat namespaces in our storage. Now I hardcoded this and everything is working, but maybe it is another possibility... -- Konrad

[Dovecot] namespace problem with dovecot 2.0
by reg9009 01 Jun '09

01 Jun '09

Hi all, I've got some namespace problems with dovecot 2.0 again. If I start dovecot 2.0 with same settings of namespace and maildir layout as dovecot 1.2, I don't see my folders above the Inbox. I see them as "INBOX/xxx" in the same root level as my INBOX. If I try to subscribe to the folders, I see them as "INBOX^xxx" (and cannot subscribe). My namespace settings: namespace private { separator = / prefix = "INBOX/" inbox = yes #hidden = yes list = yes subscriptions = yes } I tried nearly every separator/combination, but it won't work. Any ideas (to get it work like dovecot 1.2)? I've got no shared folders/namespaces, etc. Layout is plain Maildir. Regards, Sebastian

[Dovecot] Feature Missing OUTBOX Folder
by Frank Doege 01 Jun '09

01 Jun '09

Hi Dovecot People, i have switched my system from courier-imap to dovecot and iam quite happy with it, the performance is well and i had nearly no problems. One little feature iam missing is in Courier i had a folder called "Outbox" there i could paste mails which i want to sent out. In some networks its not always available to sent mails via port 21, i know i could just set up my email server to another port but it was a nice feature. Is this a big afford or is it just alittle hack ? could it done via a little plugin ? Thanks Timo & all others for the great work ! Frank

[Dovecot] imap cann't read the mail that foxmail send
by wallace0615 01 Jun '09

01 Jun '09

Hi everyone: I use dovecot only as the imap server, For smtp and pop3, I use apache james. The dovecot version: 1.1.14 And the configuration is : protocols: imap ssl_disable: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: mbox:/usr/local/edupass/mail/repo/%u:INBOX=/usr/local/edupass/mail/%u auth default: passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot-sql.conf I have no porblems to login. When I use "telent host 25" to send a email, dovecot read it no problems. But when I use outlook and foxmail to send a email, dovecot cann't read the email data. I compared the data that using the two way to send, and found the reason: use outlook and foxmail: at the beginning of the eamil data is "From zxjteacher_SP_LZU <zxjteacher_SP_LZU@myserver>"; and if I telnet host 25 to send the mail: at the beginning of the eamil data is "From <zxjteacher_SP_LZU@myserver>", so I delete "zxjteacher_SP_LZU", dovecot read it out. "zxjteacher_SP_LZU" is because that outlook and foxmail need an account name to represent the eamil address. So, anyone ever confront with this situation? Any helps appreciate. Thx.

[Dovecot] Expire Plug-in stopped
by Matt Rude 01 Jun '09

01 Jun '09

Good evening, While working with Dovecot 1.2rc4 on Fedora 10, I have been trying to get the Expire plug-in to auto delete messages for us. When I run the plug-in with the test flag, I receive the following message: /usr/local/sbin/dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test Info: amy(a)example.com/Trash: stop, expire time in future: 1242953758 All messages were deleted before the expire plug-in was added. I understand that dovecot will only expire messages after they have been in the trash or junk longer then the time in dovecot.conf. So I have let this fail since Monday, but continue to receive the same error. A quick grep for expire from my Dovecot logs doesn't show any output. Also, when I look up this error on google, I see other peaple who's output shows a real date (not 1242953758), how do I know when this date is?

[Dovecot] Assertion failure in maildir-mail.c for gzipped maildir files in 1.1.15
by David S. Madole 01 Jun '09

01 Jun '09

I attempted an upgrade from 1.1.7 to 1.1.15 and encountered an apparent regression in handling gzipped maildir files. I have tried to narrow down the conditions under which it happens and reproduce it with as simple a case as possible. The actual mail application that exposed this problem is Squirrelmail. Starting off with the index files removed from the "Folder" maildir directory: * OK Dovecot ready. 1 login x y 1 OK Logged in. 2 select Folder * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 13 EXISTS * 0 RECENT * OK [UIDVALIDITY 1220278111] UIDs valid * OK [UIDNEXT 14] Predicted next UID 2 OK [READ-WRITE] Select completed. 3 UID FETCH 3 (RFC822.SIZE INTERNALDATE) * 3 FETCH (UID 3 RFC822.SIZE 1085 INTERNALDATE "04-Jan-2004 09:23:45 -0500") 3 OK Fetch completed. 4 UID FETCH 4 (RFC822.SIZE INTERNALDATE) Connection closed by foreign host. The fetch of message 3, which is not gzipped succeeds, but the fetch of message 4, which is gzipped, fails with the following assertion in the log: Panic: imap: user=x, Status: file maildir-mail.c: line 85 (maildir_mail_stat): assertion failed: (fd != -1) Repeating, but first fetching only INTERNALDATE from the gzipped message succeeds, and once that value is cached in the index files, the same query that causes the failure before will now succeed, as it doesn't need to read the gzipped file any more to get INTERNALDATE: * OK Dovecot ready. 1 login x y 1 OK Logged in. 2 select Folder * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 13 EXISTS * 0 RECENT * OK [UIDVALIDITY 1220278111] UIDs valid * OK [UIDNEXT 14] Predicted next UID 2 OK [READ-WRITE] Select completed. 3 UID FETCH 4 (INTERNALDATE) * 4 FETCH (UID 4 INTERNALDATE "02-Dec-2003 10:39:18 -0500") 3 OK Fetch completed. 4 UID FETCH 4 (RFC822.SIZE INTERNALDATE) * 4 FETCH (UID 4 RFC822.SIZE 6035 INTERNALDATE "02-Dec-2003 10:39:18 -0500") 4 OK Fetch completed. 5 logout * BYE Logging out 5 OK Logout completed. Connection closed by foreign host. Now that the value is cached, the same previously failing query will continue to execute fine, as long as the indexes remain in place: * OK Dovecot ready. 1 login x y 1 OK Logged in. 2 select Folder * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 13 EXISTS * 0 RECENT * OK [UIDVALIDITY 1220278111] UIDs valid * OK [UIDNEXT 14] Predicted next UID 2 OK [READ-WRITE] Select completed. 3 UID FETCH 4 (RFC822.SIZE INTERNALDATE) * 4 FETCH (UID 4 RFC822.SIZE 6035 INTERNALDATE "02-Dec-2003 10:39:18 -0500") 3 OK Fetch completed. 4 logout * BYE Logging out 4 OK Logout completed. Connection closed by foreign host. Removing the indexes again, and this time first fetching just RFC822.SIZE first: * OK Dovecot ready. 1 login x y 1 OK Logged in. 2 select Folder * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 13 EXISTS * 0 RECENT * OK [UIDVALIDITY 1220278111] UIDs valid * OK [UIDNEXT 14] Predicted next UID 2 OK [READ-WRITE] Select completed. 3 UID FETCH 4 (RFC822.SIZE) * 4 FETCH (UID 4 RFC822.SIZE 6035) 3 OK Fetch completed. 4 UID FETCH 4 (RFC822.SIZE INTERNALDATE) Connection closed by foreign host. In this case, the assertion fails again. Fetching RFC822.SIZE alone does not populate the indexes in a way that then allows RFC822.SIZE and INTERNALDATE to be fetched, as fetching INTERNALDATE alone does. It's all confusing to me, hopefully this make some sense to others. Let me know if there is other testing I can help with. I'm running on Slackware 12.1 and have reproduced the same issue with both kernel 2.6.24.4 and 2.6.27.7. The filesystem is XFS. The content of the gzipped message does not seem to matter. David

[Dovecot] Missing IMAP folders after Server reboot
by Eoin Kennedy 31 May '09

31 May '09

Hi, Here is the situation, I hope somebody can help me. Our Email server running ubuntu 8.04.1 and dovecot 1.0.10 rebooted, and when it came back up the dovecot config had changed. Prior to the reboot, users stored their emails and folders in /var/mail/~username. Then the config became /var/mail/username for the main Inbox and /home/~username/mail for Folders. Now, none of the folders that users had created in their IMAP account are visible, and their contents are not in the main Inbox file. For example, the Drafts folder was there prior to the reboot, and now it had to be created in /home/username afterwards. These folders were not subfolders of the Inbox, but of the main IMAP root. All users were running Thunderbird as their client. Can they be recovered?

[Dovecot] antispam plugin and MUA-Junk folders
by Steffen Kaiser 31 May '09

31 May '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I have a configuration problem, that I ignored till now. Many MUAs tag SPAM themselves and move SPAM to a junk folder (Thunderbird uses "Junk"). It is said to not automatically train these mails, but let have an human revise them. Currently, I have configured those folders as "trash" folders for antispam, which means that those messages are essentially lost, because a move into a spam folder will not train them. -> The current antispam plugin ignores moves in and out of trash folders completely. I wonder why the move trash -> SPAM is ignored? If I configure those junk folders as "unsure" in antispam, the situation can happen, that an user selects a spam folder, the MUA identifies junk and moves the messages into its Junk folder. Current implementation would train this move as HAM. How about the following: 1) copy from * into trash or unsure -> not train 2) copy from !spam into spam -> train as SPAM 4) copy from spam or unsure into !(trash or unsure or spam) -> train as HAM 6) else -> not train Bye, - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iQEVAwUBSh0PdHWSIuGy1ktrAQKmaAf/ew1SixCkkWD2V12Jfw3mLcWnUrUSRq/J nsyMkW2//tX74wSJeMjbzlEkxN3dyfJg7f4WviGPdnUp5sqNGuS9lBfHh3ShQHtt 30+mRzVqizmcNEXBFoZXVy1K5hE8p9ssN9avahmUejBVPaSZHD0OjN5h8nFkNMDI XHU2347g03zr1MxejinWyRiKt1MFQyyJ6Y7gXNf6yascWKJA8W6b4Zu/eIH5uEW+ yiMuweaxJOwuGcwqh/qSKZTXnoCLa9rzvd8i/uZGvn7AXoT5u4P5coZkIHrh64U7 oswuYAZwxkmjGNLdGrovZadRJym16BlfVHH5g3Zo7k4nwX+kGRKyug== =9b+n -----END PGP SIGNATURE-----

I have a dumb question, is it possible to use this combination: Synchronising a remote IMAP-server and a local dovecot-IMAP-server by offlineimap (with both types = IMAP), which works very well. But it seems, that my sieve-scripts on the local dovecot server are not recognised by this combination.

[Dovecot] locking fails
by Oskar Eyb 29 May '09

29 May '09

hello! on one of my servers (freebsd 7.0-R , Jail) I have a very strange problem I guess its something about LOCKing. some programs have issued with locking: saslauthd[38127] :main : could not lock pid lock file: /var/run/saslauthd/saslauthd.pid.lock saslauthd[38127] :main : fcntl: Invalid argument dovecot: 2009-05-29 03:45:50 Info: dovecot v1.1.15 starting up dovecot: 2009-05-29 03:45:50 Info: Generating Diffie-Hellman parameters for the first time.

[Dovecot] (no subject)
by Patrick Hemmen 29 May '09

29 May '09

Hi, I use a OpenLDAP for authentication. To authenticate a full DN as the user name must be used, like "cn=jim,ou=users,dc=example,dc=com". There are several domains, like example2.com and example3.com. I want to use Dovecot with ldap and authentication binds. For testing I use "auth_bind_userdn = cn=%n,ou=users,dc=%d" and the user name must provide as "jim@example,dc=com". To allow the special chars ("=,") in user name, I extend "auth_username_chars". Now my questions. Exists a real chance to attack the ldap directory with the extended "auth_username_chars"? And it's possible to use authentication binds with the regular "auth_username_chars" and a provided user names like "jim(a)example.com" in my special ldap directory structure? Thanks in advance - Patrick

[Dovecot] Clustering dovecot?
by dovecot＠corwyn.net 29 May '09

29 May '09

Currently I have a mail server running postfix and dovecot with users in mysql. I have Outlook (blich) clients checking IMAP mail on the server. I'd like to build some fault-tolerance into that system in case I have hardware failure. I've read through: http://wiki.dovecot.org/MailLocation/SharedDisk but I feel I need more information. My basic understanding is that I'll need 2 clustered systems running with shared disk space and shared IP. Performance/load-balancing isn't an issue for me, it's just fault-tolerance that I'm worried about. I found a nice long doc for Cyrus IMAP (http://cyrusimap.web.cmu.edu//ag.html) anything similar for dovecot? Rick Rick Steeves http://www.sinister.net "The more I learn, it seems, the less I know."

[Dovecot] expire: mysql table creation error
by John Fawcett 29 May '09

29 May '09

Don't know if anyone found this already (couldn't see anything in the archives about it) but maybe this is useful to someone else who finds the same problem. When following the instructions for setting up expire on v1.2+ for mysql backend at http://wiki.dovecot.org/Plugins/Expire I got the following error: mysql> CREATE TABLE expires ( -> username varchar(100) not null, -> mailbox varchar(255) not null, -> expire_stamp integer not null, -> primary key (username, mailbox) -> ); ERROR 1071 (42000): Specified key was too long; max key length is 1000 bytes that's because it's a utf8 database where every char is 3 bytes so a 355 char index is 1065 bytes. it worked ok with the following modification: mysql> CREATE TABLE expires ( -> username varchar(100) not null, -> mailbox varchar(255) not null, -> expire_stamp integer not null, -> primary key (username, mailbox(200)) -> ); Query OK, 0 rows affected (0.00 sec) but maybe that's not such a good primary key, probably better to do: mysql> CREATE TABLE expires ( -> id integer not null auto_increment, -> username varchar(100) not null, -> mailbox varchar(255) not null, -> expire_stamp integer not null, -> primary key (id), -> key (username, mailbox(200)) -> ); Query OK, 0 rows affected (0.00 sec) John

[Dovecot] dovecot: child xxxx (login) returned error 83 (Out of memory)
by Eric Sammons 29 May '09

29 May '09

Hi, Recently started receiving the error $SUBJECT. Soon after a number of segfault errors are reported for pop3-login. Based on my configuration, I believe I am set up to receive core files; however, my ulimit -c is 0. I have tried setting ulimit -c ... in /etc/init.d/dovecot and I have tried modifying /etc/security/limits.conf. In all cases /proc/[pid]/limits continued to report that my ulimit -c value was 0. What is the best process for capturing a core file from a login process (pop3-login). I have found some similar hits on the web for this; however, none appear to lead to resolution and in most cases the implementation includes imap, mysql, etc... Here is my dovecot.conf, any insight into the cause of this problem is greatly appreciated.

[Dovecot] Timeout during imapsync
by Craig Jackson 28 May '09

28 May '09

Hi, I'm using Imapsync to sync messages from an Exchange 2003 server to a Dovecot 1.1.11 server. The problem is that users' mailboxes are huge, several gigabytes with tens of thousands of messages. First Imapsync connects to Exchange and then to Dovecot, and then starts to get Inbox info from Exchange. By the time it gets this info, the connection to Dovecot has timed out. I realize the RFC calls for a 30 minute time out which I believe is hard coded into Dovecot. If there is a way around this by making a configuration change, please tell me. I have posted the same message on the Imapsync list in an attempt to find a work around with patched Imapsync. Thanks in advance. Craig Jackson

[Dovecot] dbox verses maildir - advantages/disadvantages
by James Brown 28 May '09

28 May '09

I am migrating our mail server from Courier-IMAP to Dovecot. We currently use maildir storage format. What are the advantages and disadvantages of Dovecot's dbox format over maildir? Does anyone have any performance benchmarks for both? What do people use to test performance? We are running on a Mac OS X box (10.5.7) using Postfix 2.6. Thanks, James.

[Dovecot] Dovecot and Phpgroupware compatibility
by Carlos Xavier 28 May '09

28 May '09

Hi, recently moved our server from mbox format to Maildir format. Almost all the users are very happy with this, since the speed had increased very much. I used mb2md to do the conversion and on this task all the mailboxes that had "." (dot) on their names were converted to "_". But there is one issue with this, we also use the webmail that comes with Phpgroupware, and it uses some mailbox that have fixed named like INBOX.Sent, INBOX.Draft and so on. When their names were changed the sent messages didn't get saved anymore, so I had to move them back to the old names. After that the sent messages returned to be saved again, but another troube showed up. As they start with .INBOX and have "." on the names, Dovecot shown them as a subdirectory of the INBOX and we got some people upset with this. I need help on configuring Dovecot to not show them this way, because if you look the .INBOX.Sent either on the webmail or by outlook, the field displayed is the sender, witch is not desired. When I did the conversion, to keep the compatibility with the old server (quota, avoid I/O botleneck, etc), I set two Maildirs, one at /var/spool/mail/$USER, to be the INBOX and another at the user home. We are using Dovecot version 1.1.13, and below is the relevant configuration on use. namespace public { prefix = "#mbox/" separator = / inbox = yes list = no location= maildir:/var/spool/mail/%u/:CONTROL=~/control:INDEX=~/control } namespace private { separator = / prefix = location= maildir:~/Maildir/:CONTROL=~/control:INDEX=~/control inbox = no } Best Regards, Carlos Xavier.

[Dovecot] Does a plugin can have root privileges ?
by Fabien 28 May '09

28 May '09

Hello, I wish to get "Fetchmail Wake" works in my environment. This plugin send SIGUSR1 to fetchmail so it wakes up when mail client grabs mail. For the moment "Fetchmail Wake" is executed by mail_uid (defined in dovecot.conf) which is not enough to send signal to fetchmail daemon (and access to fetchmail.pidfile). Thank you!
