[Dovecot] Problem with Courier POP3 Migration to dovecot POP3
by Ashraf 11 Jun '09

11 Jun '09

Hi Timo/all Help me please, i am in the process of migrating courier to dovecot 1.1.14. I want to do migration as users loging so i am using this script * http://www.dovecot.org/tools/courier-dovecot-migrate.pl *, When i do use post-logging script to migrate* POP3*, its downloading messages again (*Duplicating messages)* , as some of our users prefer to leave messages on server. If i run the script manually on particular users home directory and try to download it *still duplicating messages, *as its creating whole new set of dovecot files. * * About my environment -- MailDir's stored in NFS location -- User Authenticated using MySQL my dovecot.conf looks like base_dir = /var/run/dovecot/ protocols = imap pop3 listen = *, [::] log_path =/var/log/dovecot.log info_log_path = /var/log/dovecot-info.log ssl_disable = yes login_process_per_connection = no login_processes_count = 10 login_max_processes_count = 128 login_max_connections = 256 login_greeting = Dovecot ready. mail_location = maildir:~/ mail_debug = yes mmap_disable = yes dotlock_use_excl = yes mail_nfs_index = yes lock_method = dotlock mail_drop_priv_before_exec = yes first_valid_uid = 195 max_mail_processes = 512 mail_process_size = 256 mailbox_idle_check_interval = 20 protocol imap { } protocol pop3 { *mail_executable = /usr/libexec/dovecot/postpop3.sh* mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } auth_verbose = yes auth_debug = yes auth default { mechanisms = plain passdb sql { args = /etc/dovecot-mysql.conf } userdb sql { args = /etc/dovecot-mysql.conf } user = root } dict { } plugin { } ---- my postloggin script -- $ cat /usr/libexec/dovecot/postpop3.sh #!/bin/sh # WARNING: Be sure to use mail_drop_priv_before_exec=yes, # otherwise the files are created as root! /usr/libexec/dovecot/courier-dovecot-migrate.pl --quiet --to-dovecot --recursive --convert ${HOME} # This is for pop3 exec /usr/libexec/dovecot/pop3 ---- Please advise am i doing something wrong, please guide me, let me know if you need any more info about my setup. -- Regards Ashraf

[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 11 Jun '09

11 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

Hi, Wondering if anyone could give some indication as to where to look for the cause of the following error messages. These error messages seem to occur at about the time when users are having problems logging in. Jun 8 10:33:19 host dovecot: auth(default): Master request xxxx.xxxx not found Using ldap for authentication and auth_cache is enabled, not sure if that matters. Thank you! -- Eric L. Sammons, RHCE

[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 09 Jun '09

09 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

08 Jun '09

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 06 Jun '09

06 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

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.

[Dovecot] imapmagicplus equivalent?

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

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 . . Info: foo/Trash: seq=100 uid=4178: Expunge Info: foo/Trash: seq=101 uid=4179: Expunge Info: foo/Trash: timestamp 1235292536 -> 1235325429 My guess is that mail_location is not respected by expire-tool for some reason and in second case mailbox auto-detection makes it working?

[Dovecot] expire tool - individual user/folder?

02 Jun '09

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

[Dovecot] v1.1.16 released

02 Jun '09

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] 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

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

Did you try looking for the folders by connecting to IMAP using command line. telnet servername 143 a1 login username pass a2 list "" * Check if you could see anything.

[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-----

[Dovecot] offlineimap with dovecot and sieve

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] (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."

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 29 May '09

29 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 29 May '09

29 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 29 May '09

29 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 29 May '09

29 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!

[Dovecot] Inotify instance limit for user exceeded, disabling?
by dovecot＠corwyn.net 29 May '09

29 May '09

I'm seeing this message in my /var/log/maillog: May 26 12:35:00 agencymail dovecot: IMAP(info(a)example.com): Inotify instance limit for user exceeded, disabling. Increase /proc/sys/fs/inotify/max_user_instances I rummaged through google, and found : http://www.dovecot.org/list/dovecot-cvs/2008-May/011132.html which says I need to increase /proc/sys/fs/inotify/max_user_instances (no surprise given the error message really). I can fix that with echo 256 > /proc/sys/fs/inotify/max_user_instances , but as /proc is temporary, so if I change it won't it break if/when the system reboots? The error message also implies that something has been disabled. If I increase /proc/sys/fs/inotify/max_user_instances will it fix automatically, or do I need to do something else? since it's a kernel message, I suspect just restarting dovecot won't do it. And what exactly is breaking when I receive this notification? The proc docs indicate: /proc/sys/fs/inotify (since Linux 2.6.13) This directory contains files max_queued_events, max_user_instances, and max_user_watches, that can be used to limit the amount of kernel memory consumed by the inotify interface. For further details, see <http://linux.die.net/man/7/inotify>inotify(7).

[Dovecot] A few easy pam and virtual domains questions
by Mauricio Tavares 29 May '09

29 May '09

I am using dovecot with postfix, which was setup to do virtual domains. Dovecot is setup to authenticate against pam (I know, I know) and knows to look for email in /var/spool/vmail/: virtual_mailbox_base = /var/spool/vmail I also have virtual_mailbox_maps defined as virtual_mailbox_maps = hash:/etc/postfix/vmaps.txt where I currently only have one account, % cat /etc/postfix/vmaps.txt raub(a)domain.com domain.com/raub/ % Inside raub we have the usual 3 directories, new,cur, and tmp. When I try to login through imap as raub@domain.com@mail.domain.com (i.e. since we are doing the virtual domain thingie, the username has to indicate the domain it belongs to), it will not take it. But, if I login as raub(a)mail.domain.com, it has no problems authenticating. However, it now expects to retrieve email from /var/spool/vmail/raub instead of /var/spool/vmail/domain.com/raub. Why would it be doing that? Could it be that pam reports raub to be a local account and as a result simply ignoring vmaps.txt? I asked dovecot to log everything it could. When I checked the log file, the following line screamed at me: dovecot: May 27 14:40:28 Info: IMAP(raub): maildir++: root=/var/spool/vmail//raub, index=, control=, inbox=/var/spool/vmail//raub Note the "//" in root and inbox declarations; between those slashes I would expect to be domain.com. Compounding the problem, and perhaps a clue of how pam is telling what these accounts are, postfix is completely ignoring /var/spool/vmail, placing the emails in /home/raub/Maildir (account is actually being nfs-automounted and user authenticated through ldap through pam). Once again I am guessing it too is being told raub is a local user; am I correct?

[Dovecot] RFC 3501 section 7
by Scott Haneda 27 May '09

27 May '09

Hello, been lurking a while, about to move over to Dovecot soon. I have a nice test machine up and running. My previous email server when talking IMAP to Apple Mail, will eventually go "deaf" and new messages will not make it to the Inbox of Apple Mail Client. A restart of the desktop application is required. I am told that the reason for this is that my current email server adheres to RFC 3501, specifically section 7, the second paragraph of which says: The client MUST be prepared to accept any response at all times. Apparently, Apple Mail is not adhering to that, and my email server is sending out that type of response. However, I look at this list, for which I am not entirely sure how accurate the actual test is: http://www.imapwiki.org/ImapTest/ServerStatus It lists Dovecot as one of only two that are fully compliant IMAP servers. Congrats on that. My questions are: Does Dovecot in fact support correctly the above mentioned RFC and subsection? I assume so. That being the case, I have not had issues in my testing of Dovecot, nor heard reports of Apple Mail and IMAP having any significant problems. How, if that is the case, can Apple Mail and Dovecot work well with each other, and my current email server is not able to? My primary reason for moving to Dovecot is to not be burdened by this issue, as well as have what I consider to be a more advanced storage mechanism for the actual messages. What I would like to avoid, is spending a lot of time migrating thousands of users to a new system, to only have them burdened by the same inability to have email come to them without an application relaunch. Thank you for any insight on this. * I have filed a bug report with Apple, which was accepted. Their system does not allow me to see the status on the report once it has been closed. -- Scott * If you contact me off list replace talklists@ with scott@ *

[Dovecot] Secure Sockets Layer client certificate authentication
by Stephen Feyrer 26 May '09

26 May '09

Hi everyone. Please note, I've asked a very similar question before and I apologize for sounding like a broken record. Well here it goes. What I want to do is authenticate my users using a certificate. Thereby authenticating both the user and server with strong tokens that are centrally managed. In the worst case scenario the user should only need to enter a password for the certificate store and then the certificate should trigger the appropriate level of access to their account.

Hi list, I use dovecot 1.1.11 on ubuntu 9.04, when I want to send a message to an email adres on this mailserver I get this error: status=bounced (Command died with signal 11: "/usr/lib/dovecot/deliver". The folders where the email should be delivered are created so it does not look like a permission problem. I connect to a mysql database where the email accoutn info is stored, this works. I use the same setup on an ubuntu 8.04 server with dovecot 1 and I have no problems on that server. What am I overlooking here?

[Dovecot] libsieve problems / wishes
by Steffen Kaiser 26 May '09

26 May '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I'm trying libsieve (853:42e154b8792e) to cope with our current installation, the following issues arise: 1) vacation addresses are compared case-sensitivly, e.g.: vacation :addresses [ "Steffen.Kaiser(a)example.com" ] ""; it won't match "steffen.kaiser@...". attached patch makes a first shot about that problem, leaving: 1a) maybe one should lower-case :addresses argument at compile time and my_address at run-time and then use strcmp() again. 1b) duplicate checks are case-sensitive, too. This is probably no big issue, because if the same person uses different variants of his/her mail address for sending, s/he does not deserve better. 1c) Suppression of replies to own mails are case-sensitive, too. Well, many people I know test that "it just works" by sending themselves a mail. I would disable this check. 2) we have about 157 ways to write the domain part. Not all accounts are available in all of them, but it's close to it. The old vacation program we used prior to "cmusieve" didn't care about the domain unless explicitly given. It was quite painful. Attached patch adds a "domainless" variant of :addresses arguments in such way, that vacation :addresses [ "Steffen.Kaiser" ] ""; matches any domain. Ideally, it would be better to specify all valid domains, but perhaps one can leave that for another approach with a different syntax, e.g. with "@*" as domain? Maybe, there is a better approach. Now there is possibility that common local parts are matched from alien domains easily. If to specify a set of "default" domains would be an option for libsieve, what is the suggested way: - - as user-option via dovecot.conf? - - as admin-enforced Sieve-script that sets some internal variables? aka using the multi-script capability - - ??? 3) Because I try to migrate from cmusieve v1.0, I have a name issue with "imapflags". README sec "* Supports all extensions provided by the original CMUSieve plugin:" and sec "Implementation Status" explains that "imapflags" is available. This is not true entirly: "imapflags" is not, lib-sieve uses the name "imap4flags" as defined by RFC. So, it leaves me with two options: 3a) convert all user scripts and hack Horde-Ingo, or 3b) have libsieve accept the alias "imapflags" for the extension "imap4flags". Would it be worhtwhile for libsieve to implement aliases for extensions, so that they are available in require by more than one name? About Horde-Ingo, maybe they have an update to use "imap4flags", too, but it looks like that I upgrade Dovecot before Horde.

[Dovecot] Maildir with LAYOUT=fs not working
by Rich Wales 26 May '09

26 May '09

I'm considering converting a Cyrus system (managing my family's e-mail) to Dovecot. I'm trying Dovecot 1.1.15 on an Ubuntu 9.04 (2.6.28-11-server) system. My production server is currently running Cyrus 2.3.14. Since I have a huge number of folders and subfolders, I need to use LAYOUT=fs. However, it's not working consistently. I tried setting up a test account in Thunderbird (2.0.0.21), and I was able to create folders under the Inbox, and they showed up as nested subdirectories under my ~/Maildir on my mail server. So far, so good. However, when I tried a home-grown Perl script (an archival scheme for my work e-mail), Dovecot wouldn't create subfolders properly; instead of nesting them (as I thought LAYOUT=fs would do), it used a flat layout. Here is a trace (generated by my Perl script) of an IMAP session. This was supposed to log in as the user "stanford" (the name of my archival account); create a folder named "2009" if not already present; create (again, if not already there) a "2009-05" folder inside the "2009" folder; and, finally, save a message (marked as seen) inside the "2009-05" folder. 1 LOGIN XXXXXXXX XXXXXXXX1 OK Logged in. 2 STATUS user.stanford.2009 (MESSAGES)* STATUS "user.stanford.2009" (MESSAGES 0) 2 OK Status completed. 3 STATUS user.stanford.2009.2009-05 (MESSAGES)* STATUS "user.stanford.2009.2009-05" (MESSAGES 3) 3 OK Status completed. 4 APPEND user.stanford.2009.2009-05 (\Seen) {4043} + OK (message text here . . .) 4 OK [APPENDUID 1243306507 4] Append completed. 5 LOGOUT* BYE Logging out The above works perfectly when I'm talking to my Cyrus server. However, when I tried the same thing with Dovecot, I got a folder named "user.stanford.2009" in the "stanford" account's Maildir, and then another folder named "user.stanford.2009.2009-05" (again, in the Maildir -- NOT nested in the "user.stanford.2009" folder) -- and the message was stored in the "user.stanford.2009.2009-05" folder. I tried changing my Perl script to use "INBOX" instead of "user.stanford" -- but the result was basically the same, except I got new folders named "INBOX.2009" and "INBOX.2009.2009-05" directly in my archival account's Maildir. Finally, I tried omitting any prefix at all on the folder names, and I got new folders named "2009" and "2009.2009-05" -- again, directly in Maildir -- no nesting of one folder within another. I suppose I actually have two issues here -- the lack of folder nesting (even with LAYOUT=fs), and also Dovecot's failure to recognize a "user.XXX." prefix on a mailbox name as designating user XXX's inbox (something that seems to work fine on Cyrus). My Cyrus server currently has over 1,600 folders and subfolders, so I absolutely can't / won't consider switching it to Dovecot unless I can get the nested filesystem layout working. Any thoughts? -- Rich Wales / richw(a)richw.org / richw(a)stanford.edu Wikipedia: http://en.wikipedia.org/wiki/User:Richwales Facebook: http://www.new.facebook.com/profile.php?id=206680

[Dovecot] lda deliver per instance sieve configuration
by J.P. Trosclair 26 May '09

26 May '09

I'd like to override the sieve settings in dovecot.conf for a deliver instance that is being run from a custom archiving script. This is dovecot 1.0.15 on debian lenny. Is this possible? Doesn't appear to be looking through the WIKI. If it's not any suggestions? The problem is the user specific sieve scripts override where the archived mail is supposed to be stored (maildir:~/.Archives.YYYY-MM) so I'd like to disable their sieve scripts while the archived mail delivery via deliver is taking place. Thanks, J.P.

[Dovecot] Separate home and mail folders problem on delivery
by Николай Бочев 26 May '09

26 May '09

Hello, I am using dovecot 1.2rc series on my mail server combined with postfix ( virtual users with postgre ). I have setup separate home and mail locations. It works fine ( with sieve etc. ). The user home folders are in /home/vmail/%d/%n and mailboxes are in /srv/mail/%d/%n . The permissions are fine and everything is working except in the following case : If a user does not have a home dir already crated ( the home dirs get auto created when creating a sieve script through managesieve for example ), and he recieves a message with an attachment, the delivery fails with the following error : May 19 10:47:28 mail postfix/pipe[2759]: 969531007B: to=<office(a)grandstarco.com>, relay=dovecot, delay=2296, delays=2296/0.2/0/0.06, dsn=4.3.0, status=deferred (temporary failure) The Dovecot deliver log says : > 2009-05-19 10:47:28 deliver(office(a)grandstarco.com): Error: creat(/home/vmail/grandstarco.com/office/.temp.mail.dodo.bg.2760.1242719248… failed: No such file or directory > 2009-05-19 10:47:28 deliver(office(a)grandstarco.com): Error: copy: i_stream_read() failed: No such file or directory > 2009-05-19 10:47:28 deliver(office(a)grandstarco.com): Error: sieve: msgid=<1242716935.24056.6.camel(a)shiny.bgservice.local>: failed to store into mailbox 'INBOX': Internal error occurred.
