[Dovecot] doveadm move from one user's mailbox to another user's mailbox?
by Ralf Hildebrandt 04 Jan '12

04 Jan '12

Is something along the lines: doveadm move -u sourceuser destinationuser:/inbox search_query possible with 2.0.16? I want to move mails from a backup mailbox (which has no valid password assigned) to a "restore" mailbox (which *HAS* a password assigned to it). -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

[Dovecot] migrate dovecot files 1.2.16 to 2.0.13 (OpenBSD 5.0)
by Wesley M. 04 Jan '12

04 Jan '12

Hi, I have a mailserver(Postfix+MySql) on OpenBSD 4.9 with Dovecot 1.2.16, all works fine. Now i want to do the same but on OpenBSD 5.0. I meet problems using dovecot 2.0.13 on OpenBSD 5.0. Some tests (on the box): telnet 127.0.0.1 110 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. Connection closed by foreign host. telnet 127.0.0.1 143 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. Connection closed by foreign host.

[Dovecot] error bad file number with compressed mbox files
by Jürgen Obermann 04 Jan '12

04 Jan '12

Hello, can dsync convert from compressed mbox to compressed mdbox format? When I use compressed mbox files, either with gzip or with bzip2, I can read the mails as usual, but I find the following errors in dovecots log file: imap(userxy): Error: nfs_flush_fcntl: fcntl(/home/hrz/userxy/Mail/mymbox.gz, F_RDLCK) failed: Bad file number imap(userxy): Error: nfs_flush_fcntl: fcntl(/home/hrz/userxy/Mail/mymbox.bz2, F_RDLCK) failed: Bad file number These errors also appear when I use dsync to convert the compressed mbox to mdbox format on a second dovecot server: /opt/local/bin/dsync -v -u userxy backup mdbox:/sanpool/mail/home/hrz/userxy/mdbox dsync(userxy): Error: nfs_flush_fcntl: fcntl(/home/hrz/userxy/Mail/mymbox.gz, F_RDLCK) failed: Bad file number But now dovecot does not find the mails in the folder mymbox.gz on the second dovecot server in mdbox format!

I used to work for IBM, so I've been a bit uneasy about pushing GPFS too hard publicly, for risk of being accused of being biased. But I changed job in November, so now I'm only a satisfied customer :-) Pros: Extremely simple to configure and manage. Assuming root on all nodes can ssh freely, and port 1191/tcp is open between the nodes, these are the commands to create the cluster, create a NSD (network shared disks), and create a filesystem: # echo hostname1:manager-quorum > NodeFile # "manager" means this node can be selected as filesystem manager # echo hostname2:manager-quorum >> NodeFile # "quorum" means this node has a vote in the quorum selection # echo hostname3:manager-quorum >> NodeFile # all my nodes are usually the same, so they all have same roles. # mmcrcluster -n NodeFile -p $(hostname) -A ### sdb1 is either a local disk on hostname1 (in which case the other nodes will access it over tcp to ### hostname1), or a SAN-disk that they can access directly over FC/iSCSI. # echo sdb1:hostname1::dataAndMetadata:: > DescFile # This disk can be used for both data and metadata # mmcrnsd -F DescFile # mmstartup -A # starts GPFS services on all nodes # mmcrfs /gpfs1 gpfs1 -F DescFile # mount /gpfs1 You can add and remove disks from the filesystem, and change most settings without downtime. You can scale out your workload by adding more nodes (SAN attached or not), and scale out your disk performance by adding more disks on the fly. (IBM uses GPFS to create scale-out NAS solutions http://www-03.ibm.com/systems/storage/network/sonas/ , which highlights a few of the features available with GPFS) There's no problem running GPFS on other vendors disk systems. I've used Nexsan SATAboy earlier, for a HPC cluster. One can easily move from one disksystem to another without downtime. Cons: It has it's own page cache, staticly configured. So you don't get the "all available memory used for page caching" behaviour as you normally do on linux. There is a kernel module that needs to be rebuilt on every upgrade. It's a simple process, but it needs to be done and means we can't just run "yum update ; reboot" to upgrade. % export SHARKCLONEROOT=/usr/lpp/mmfs/src % cp /usr/lpp/mmfs/src/config/site.mcr.proto /usr/lpp/mmfs/src/config/site.mcr % vi /usr/lpp/mmfs/src/config/site.mcr # correct GPFS_ARCH, LINUX_DISTRIBUTION and LINUX_KERNEL_VERSION % cd /usr/lpp/mmfs/src/ ; make clean ; make World % su - root # export SHARKCLONEROOT=/usr/lpp/mmfs/src # cd /usr/lpp/mmfs/src/ ; make InstallImages > > To this point IIRC everyone here doing clusters is using NFS, GFS, or > OCFS. Each has its downsides, mostly because everyone is using maildir. > NFS has locking issues with shared dovecot index files. GFS and OCFS > have filesystem metadata performance issues. How does GPFS perform with > your maildir workload? Maildir is likely a worst case type workload for filesystems. Millions of tiny-tiny files, making all IO random, and getting minimal controller read cache utilized (unless you can cache all active files). So I've concluded that our performance issues are mostly design errors (and the fact that there were no better mail storage formats than maildir at the time these servers were implemented). I expect moving to mdbox will fix all our performance issues. I *think* GPFS is as good as it gets for maildir storage on clusterfs, but have no number to back that up ... Would be very interesting if we could somehow compare numbers for a few clusterfs'. I believe our main limitation in this setup is the iops we can get from the backend storage system. It's hard to balance the IO over enough RAID arrays (the fs is spread over 11 RAID5 arrays of 5 disks each), and we're always having hotspots. Right now two arrays are doing <100 iops, while others are doing 4-500 iops. Would very much like to replace it by something smarter where we can utilize SSDs for active data and something slower for stale data. GPFS can manage this by itself trough it's ILM interface, but we don't have the very fast storage to put in as tier-1. -jf

[Dovecot] Problem with huge IMAP Archive after Courier migration
by Preacher 04 Jan '12

04 Jan '12

I have a mail server running Debian 6.0 with Courier IMAP to store project related mail. Currently the maildir of the archive (one user) contains about 37GB of data. Our staff is acessing the archive via Outlook 2007 where they drag their Exchange inbox or sent files to it. The problem with courier is that is sometimes mixes up headers with message bodies, so I wanted to migrate to dovecot. I tried this on my proxy running Debian 7.0 with some test data and this worked fine (OK, spent some hours to get the config files done - Dovecot without authentication). Dovecot version here is 2.0.15. Tried it with our productive system today, but got Dovecot 1.2.15 installed on Debian 6.0 Config files and parameters I took from my test system were not compatible and I didn't get it to work. So I forced to install the Debisn 7.0 packages with 2.0.15 and finally got the server running, I also restarted the whole machine to empty caches. But the problem I got was that in the huge folder hierarchy the downloaded headers in the individual folders disappeared, some folders showed a few very old messages, some none. Also some subfolders disappeared. I checked this with Outlook and Thunderbird. The difference was, that Thunderbird shows more messages (but not all) than Outlook in some folders, but also none in some others. Outlook brought up a message in some cases, that the connection timed out, although I set the timeout to 60s. After being frustrated uninstalled dovecot, went back to Courier and folder contents are displayed correctly again. Anyone a clue what's wrong here? Finally some config information: proxy-server:~# dovecot -n # 2.0.15: /etc/dovecot/dovecot.conf # OS: Linux 3.1.0-1-686-pae i686 Debian wheezy/sid auth_debug_passwords = yes auth_mechanisms = plain login disable_plaintext_auth = no namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap ssl = no ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd }

[Dovecot] Maildir migration and uids
by David Jonas 03 Jan '12

03 Jan '12

I'm in the process of migrating a large number of maildirs to a 3rd party dovecot server (from a dovecot server). Tests have shown that using imap to sync the accounts doesn't preserve the uidl for pop3 access. My current attempt is to convert the maildir to mbox and add an X-UIDL header in the process. Run a second dovecot that serves the converted mbox. But dovecot's docs say, "None of these headers are sent to IMAP/POP3 clients when they read the mail". Is there any way to sync these maildirs to the new server and maintain the uids? The real goal is keep customers email clients happy when they are pointed at the new server. Am I just wishing?

[Dovecot] Deliver all addresses to the same mdbox:?

[Dovecot] Multiple Maildirs per Virtual User
by Ruslan Nabioullin 03 Jan '12

03 Jan '12

How would it be possible to configure dovecot (2.0.16) in such a way that it would serve several maildirs (e.g., INBOX, INBOX.Drafts, INBOX.Sent, forum_email, [Gmail].Trash, etc.) per virtual user? I am only able to specify a single maildir, but I want all maildirs in /home/my-username/mail/account1/ to be served. e.g., /etc/dovecot/passwd: my-username_account1:{PLAIN}password:my-username:my-group::::userdb_mail=maildir:/home/my-username/mail/account1/INBOX Thanks in advance, Ruslan -- Ruslan Nabioullin rnabioullin(a)gmail.com

[Dovecot] Compressing existing maildirs
by Jan-Frode Myklebust 03 Jan '12

03 Jan '12

I've just enabled zlib for our users, and am looking at how to compress the existing files. The routine for doing this at http://wiki2.dovecot.org/Plugins/Zlib seems a bit complicated. What do you think about simply doing: find /var/vmail -type f -name "*,S=*" -mtime +1 -exec gzip -S Z -6 '{}' + I.e. find all maildir-files: - with size in the name ("*,S=*") - modified before I enabled zlib plugin - compress them - add the Z suffix - keep timestamps (gzip does that by default) It's of course racy without the maildirlock, but are there any other problems with this approach ? -jf

[Dovecot] Dsync fails on second sync for folders with dot in the name
by Jan-Frode Myklebust 03 Jan '12

03 Jan '12

I'm in the processes of running our first dsync backup of all users (from maildir to mdbox on remote server), and one problem I'm hitting that dsync will work fine on first run for some users, and then reliably fail whenever I try a new run: $ sudo dsync -u janfrode(a)example.net backup ssh -q mailbackup(a)repo1.example.net dsync -u janfrode(a)example.net $ sudo dsync -u janfrode(a)example.net backup ssh -q mailbackup(a)repo1.example.net dsync -u janfrode(a)example.net dsync-remote(janfrode(a)example.net): Error: Can't delete mailbox directory INBOX/a: Mailbox has children, delete them first The problem here seems to be that this user has a maildir named ".a.b". On the backup side I see this as "a/b/". So dsync doesn't quite seem to agree with itself for how to handle folders with dot in the name. -jf

[Dovecot] lmtp-postlogin ?

We have last-login tracking for imap and pop, and I intend to use this for deciding which users to backup daily. But, it would also be nice to backup users who has only received messages, but not logged in lately.. So is it possible to implement "last-login" tracking for lmtp ? I naively tried copying the settings from imap, but it didn't work: service lmtp-postlogin { executable = script-login /usr/local/sbin/lmtp-postlogin.sh unix_listener lmtp-postlogin { } } service lmtp { executable = lmtp lmtp-postlogin <snip> -jf

[Dovecot] Newbie: LDA Isn't Logging
by Michael Papet 03 Jan '12

03 Jan '12

Hi, I'm a newbie having some trouble getting deliver to log anything. Related to this, there are no return values unless the -d is missing. I'm using LDAP to store virtual domain and user account information. Test #1: /usr/lib/dovecot/deliver -e -f mpapet(a)yahoo.com -d zed(a)mailswansong.dom < bad.mail Expected result: supposed to fail, there's no zed account via ldap lookup and supposed to get a return code per the wiki at http://wiki2.dovecot.org/LDA. Supposed to log too. Actual result: nothing gets delivered, no return code, nothing is logged. Test #2: /usr/lib/dovecot/deliver -f mpapet(a)yahoo.com -d dude(a)mailswansong.dom < good.mail Expected result: deliver to dude and return 0. Actual result: delivers, but no return code. Nothing logged. The wiki is vague about the difficulties of getting deliver LDA to log, but I thought I had it covered in my config. I even opened permissions up wide (777) on my log files specified below. Nothing gets logged. The ONLY thing changed in 15-lda.conf is as follows. protocol lda { # Space separated list of plugins to load (default is global mail_plugins). #mail_plugins = $mail_plugins log_path = /var/log/dovecot/lda.log info_log_path = /var/log/dovecot/lda-info.log service auth { unix_listener auth-client { mode = 0600 user = vmail } } I'm running plain Debian Testing and used dovecot from Debian's repository. The end-goal is to write a qpsmtpd queue plugin, but I need to figure out what's the matter first. Thanks in advance. mpapet

[Dovecot] dsync / separator / namespace config-problem

03 Jan '12

Guess I don't quite get namespaces, but we have the following namespace configured: $ doveconf namespace namespace { hidden = no inbox = yes list = yes location = prefix = INBOX. separator = subscriptions = yes type = private } But when I try running dsync it complains: $ sudo -u atmail dsync -u janfrode(a)tanso.net mirror mdbox:/tmp/janfrodeboks dsync(atmail): Error: user janfrode(a)tanso.net: Initialization failed: namespace configuration error: list=yes requires prefix=INBOX. to end with separator dsync(atmail): Fatal: User init failed I can fix this by adding "separator = ." to the namespace and dsync is happy, but is changing this now safe, or will this affect existing clients? -jf

[Dovecot] Trouble with proxy_maybe and auth_default_realm
by Gedalya 01 Jan '12

01 Jan '12

Hello, I'm using proxy_maybe and auth_default_realm. It seems that when a user logs in without the domain name, relying on auth_default_realm, and the "host" field points to the local server, I get the Proxying loops to itself error.

[Dovecot] imap process limits problem
by Calvin Cochran 01 Jan '12

01 Jan '12

I am having a problem with the number of current processes that I cannot seem to diagnose adequately, and is a possible bug. This will be a bit long, but usually more info is better. I am running dovecot 2.0.16 on a CentOS 5 x86_64 server with the mailstore on gfs (output from dovecot -n at bottom). This is an imap issue. This is mostly to do with one client, but none of my tests indicate an issue with the client side. We have mail_max_userip_connections = 10 for imap, but they are not hitting the limit. We also have verbose_proctitle = yes to help in diagnosing the situation. Most of our clients, including this one, use SSL or TLS and connect on 993. As I understand it, that should have an imap-login process and an imap process per authenticated session. Based on some other diagnosis the client seems to have a PC using Outlook 2010 and an i-device (phone or pad, not sure), both on the office network, and both with imap connections to the server. Based on my analysis it seems like the client is connecting, authenticating, and then closing the session, but the imap-login process does not drop until it times out server side (I don't know a way to tell which device, the PC or i???). One odd thing is that the tcp sessions time out at 2 hours and 11 minutes (this is where the possible bug aspect comes in). I have put a strace on the process, and there does not appear to be any traffic, so I don't understand why the 30 min timeout isn't happening. Based on netstat and verbose_proctitle, at this moment there are 99 connections from the IP in question, all of which show in ps output as: dovecot/imap-login [1 connections (1 TLS)] My understanding is that means they have successfully authenticated, and that there should be line with dovecot/imap [username ip TLS] in ps output, but there isn't, so I am taking that to mean the client closed the imap session. The client ip address puts them on comcast (tcp resets?) and we do have a load balancer in front of two servers, just to add a little challenge to the diagnosis fun. The short term fix has been to increase the process limits. However, it is clearly not a workable solution to increase the limits by 100 every time someone starts accessing the server with their new i??? device. I appreciate your thoughts on this, and I am happy to provide additional useful debug info if I have missed something. Thanks, Calvin output from dovecot -n auth_mechanisms = plain apop cram-md5 auth_verbose = yes auth_verbose_passwords = plain auth_worker_max_count = 400 default_process_limit = 400 disable_plaintext_auth = no first_valid_uid = 89 last_valid_uid = 89 login_greeting = EMCS ready. mail_fsync = never maildir_very_dirty_syncs = yes mmap_disable = yes passdb { driver = vpopmail } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size mail_log_group_events = no } protocols = imap pop3 shutdown_clients = no ssl_cert = </var/qmail/control/servercert.pem ssl_key = </var/qmail/control/servercert.pem userdb { driver = vpopmail } verbose_proctitle = yes protocol imap { mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 3 pop3_no_flag_updates = yes pop3_uidl_format = %f }

[Dovecot] mbox, hierarchical folders/folders and IMAP
by Alexander Chekalin 30 Dec '11

30 Dec '11

Hello, I'm now dealing with funny problem. I try to use Dovecot (2.1.rc1, actually) and mbox format to store old mailing, to keep logic of "one folder = one file". If I'd choose Maildir, I'd be able to create hierarchical folders (like "OldMail -> Maillists -> Dovecot"), and in fact on disk such a folders would be stored as real folders with dots in their names. In PHP it is easy to create with "imap_createmailbox()" function, I'd simple fire it 3 times (for "OldMail", for "OldMail.Maillists" and for "OldMail.Maillists.Dovecot"). But when I do the same with mbox, in fact it creates separate files (indeed, named "OldMail", "OldMail.Maillists" and "OldMail.Maillists.Dovecot") instead of creating filesystem folders ("OldMail/Maillists/Dovecot"). PHP is not guilty, Thunderbird won't create such folders as well. I can only create folders myself (say, with mkdir in the shell), chown it, and the it perfectly works in IMAP. Now I just wanted to know, are there any way to create IMAP-folders and subfolders using standard IMAP functionality? Thank you, Alexander

[Dovecot] Using Amazon S3 storage for Maildir ?
by Forrest Aldrich 30 Dec '11

30 Dec '11

I wonder if anyone has tried using an IMAP server with Amazon S3 as a backend. There would be many factors to consider (speed, etc). However, moreso, I don't know that Maildir(++) would support multiple folders that might be linked into the cloud. For example, higher-I/O local incoming mail is on disk, some folders archived on S3. Could be easily done by simply creating another account and storing its Maildir in S3 -- Curious....

[Dovecot] How to serve a subset of IMAP folders for hand held devices.
by David Pottage 30 Dec '11

30 Dec '11

Hello I am currently running dovecot 1.2.15 on my home server. I have over 200 folders in personal email account, and I have found that my smart-phone does not work well trying to display that many folders. I solved the problem by creating a second instance of dovecot running on a non standard port, and configured it to serve only a subset my email folders, so that way the email client on my smartphone works well and I can read the emails I am interested in on the move. The process of configuring two instances of dovecot on the same machine serving different views of the same mailbox was faily complex, so I think it would be worth documenting the process in an FAQ or suchlike for other users. I thought a good place to write up my method would be in the HowTo section of the Dovecot Wiki. Is that a good idea? Can I request an account to edit the Wiki, or should I send a draft text to an editor? Are there any Dovecot experts here who can review my methods and suggest improvements? -- David Pottage

[Dovecot] /usr/lib/dovecot/imap ignores log settings?

Hi Dovecot peeps, I'm enjoying running /usr/lib/dovecot/imap directly as a PREAUTH IMAP pipe. I find that it outputs log messages whose severity is INFO to stdout. I'm running it as follows: /usr/lib/dovecot/imap -c /tmp/dovecot.conf and I see the following messages output to stdout: * PREAUTH [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS] Logged in as paulproteus imap(paulproteus): Info: Connection closed bytes=0/305 Naturally, the first line is great. My /tmp/dovecot.conf is: <cut here> # single-dbox mail_location = sdbox:~/Maildir/dbox log_path = syslog info_log_path = /dev/null </cut> I'm also attaching strace output, created by running this command: echo | strace /usr/lib/dovecot/imap -c /tmp/dovecot.conf > /tmp/straced 2>&1 (The point of the "echo | " is to provide a newline and then EOF to /usr/lib/dovecot/imap.) You can see in the strace output that /usr/lib/dovecot/imap outputs the "Connection closed" message to file descriptor 2. I'd like that message to actually not be printed, which is why I set log_path to syslog. -- Asheesh.

[Dovecot] Received date no longer email date?
by Brian L. Matthews 29 Dec '11

29 Dec '11

I just upgrade from dovecot 1.2 to dovecot 2.0.16. I use dovecot as a local IMAP server to archive email from my corporate email account (on Exchange). I don't have any automated archiving, I just periodically move messages from my Exchange inbox to the IMAP inbox. I'm on Mac OS X 10.6.8 using Entourage as my mail client. In the previous version of dovecot, the Received date of the email was preserved when I moved a message, but it's not in 2.0.16, it's set to the date and time I move the message. If I open a message, the date displayed is the date on the message as expected. I converted my config from 1.2 with $ doveconf -n -c dovecot.conf > dovecot-2.conf It spit out various warnings but, once I'd created a dovenull user, seemed to work fine. Here's my configuration info: $ dovecot --version 2.0.16 $ dovecot -n # 2.0.16: /usr/local/etc/dovecot/dovecot.conf # OS: Darwin 10.8.0 i386 disable_plaintext_auth = no listen = 127.0.0.1 log_path = /var/log/dovecot.log mail_location = maildir:~/Maildir passdb { args = login driver = pam } service auth { user = root } service imap-login { process_limit = 16 } service imap { process_limit = 64 } ssl = no userdb { driver = passwd } I'd like to get it back to preserving the Received date, any help you can provide will be appreciated.

[Dovecot] proxying, SSL, and client certificate
by Mike Abbott 29 Dec '11

29 Dec '11

How do I configure dovecot-2.0.x to present a client SSL certificate when proxying? If dovecot on server1.example.com has: passdb { driver = static args = proxy=y host=server2.example.com nopassword=y ssl=yes } and dovecot on server2.example.com has: ssl_verify_client_cert = yes auth_ssl_require_client_cert = yes then when a client connects to server1 and authenticates, a connection is established to server2 but the SSL handshake fails because server1 doesn't present a client certificate. I don't see where ssl_client_ctx is tied to a client certificate in ssl-proxy-openssl.c. Thanks.

[Dovecot] Dovecot imap proxy to nginx, incompatible
by David Jonas 29 Dec '11

29 Dec '11

It appears that using dovecot to proxy to nginx imap proxy doesn't work. >From tcpdump and browsing the source it appears dovecot sends, C CAPABILITY\r\nL LOGIN <user> <pass>\r\n and nginx only responds to the CAPABILITY command. Is this a problem with dovecot sending the two commands without waiting for the first to complete or is it nginx's trouble with not handling it correctly? A quick test with a perl script confirms: #!/usr/bin/perl -w $|++; use IO::Socket; use strict; my ($host, $user, $pass) = @ARGV; my $s = new IO::Socket::INET(Proto => 'tcp', PeerAddr => $host, PeerPort => 143); die "Could not create socket $!\n" unless $s; while(<$s>) { print $_; last if /OK/; } print $s "C CAPABILITY\r\nL LOGIN $user $pass\r\n"; while(<$s>) { print $_; last if /OK/; } print $s "Q logout\r\n"; while(<$s>) { print $_; last if /OK/; } close($s); ## Output: * CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1 QUOTA AUTH=PLAIN C OK completed * BYE Q OK completed

[Dovecot] Corrupted index cache file and high CPU usage
by hydra 24 Dec '11

24 Dec '11

I suspect, that dovecot v2.0.16 under Linux (tested on Gentoo 3.0.4 Hardened, Gentoo 3.0.6, Gentoo 3.1.4) causes 100% cpu utilization when index.cache is broken and doveadm is lanched. Dovecot uses LDAP as the userdb and provides IMAP and LDA. Because each user has a quota, the doveadm's expunge functionality is used to get rid of old trashed mail. The mail log: Dec 12 07:38:59 www dovecot: imap(user): Error: Corrupted index cache file /var/data/mail/domain.tld/user/mail/dovecot.index.cache: invalid record size Doveadm is launched as: doveadm -D expunge -A mailbox Trash savedbefore 1w Mail is stored on ext4 and flush will use all of the CPU capacity like this: load average: 4.00, 4.01, 4.05 ps: root 26401 98.2 0.0 0 0 ?

When this happens, I cannot unmount the drive nor a system reboot works. Thank you !

[Dovecot] Limit maximum connections for user/IP on proxy
by Martin Abrahamsson 23 Dec '11

23 Dec '11

Hi, Is it possible to limit the maximum number of IMAP connections allowed for a user from each IP address, on the proxy server instead of on the mail store server? mail_max_userip_connections works well when the client is connection to the mail store without proxy, but when using proxies the POP/IMAP server will register the remote IP (rip) as the proxy server's IP address - thus a low limit will be reached quite easily. Thanks -- Martin Abrahamsson

[Dovecot] Patch for dovecot 1.2.16 (and .17) for vpopmail module
by Alessio Cecchi 22 Dec '11

22 Dec '11

Hi Timo, I love dovecot but I love also vpopmail and its functions for manage user limits (via vmoduser). Unfortunately in dovecot 1.2.x auth default set to use "vpopmail" is unable to apply this limits. Only if used with checkpassword limits works fine but in the dovecot.log only user (without @domain) is logged. So, based on the code of dovecot 2.0, I have created this very simple patch that correct this bug.

[Dovecot] Backing Up To Windows File Server
by Asai 22 Dec '11

22 Dec '11

Greetings, Working with dsync and setting up backups to a Windows file server. Problem seems to be that Windows is renaming the dovecot mail files (maildir) to Windows friendly filenames, and losing the Dovecot name. For example, 1323817925.M36368P32049.triata.globalchangemultimedia.net,S=2255,W=2318:2,S becomes 1AETPH~X. Does anyone have any ideas about how to tell Windows to not do this? Or is it not possible? -- --asai

[Dovecot] lmtp logging incomplete (does not tell what mailbox mail is actually being saved to!)
by Gary Chodos 22 Dec '11

22 Dec '11

We created a new virtual domain and created a user in that domain in our pgsql database. Instead of creating any directory structure in /home/virtual/mail/<domain>/<user>, I just sent a test email to see if dovecot's lmtp would autocreate. And it did! And mail appears to be delivered to an inbox.. but, logging is weird and I'm not sure everything is working as it should because: Dec 20 23:01:28 mx dovecot: lmtp(21458, user(a)example.com) lUDFG8tZ8U7SUwAAO3tENA: msgid=<20111221040122.GP13367(a)hostname.example.org>: saved mail to . so why doesn't dovecot log where mail is stored/saved? thanks, Gary

[Dovecot] Problem listing SPECIAL-USE flags
by Patrick Ben Koetter 21 Dec '11

21 Dec '11

Timo, we want to implement SPECIAL-USE in Thunderbird (TB), but we've run into problems. I believe you could help change that. Here's the problem: By default TB only lists subscribed (LSUB) folders when it accesses an IMAP server. However when I do a LSUB on recent Dovecot 2.1 code from mercurial I don't get to see the SPECIAL-USE flags. Therefore TB fails to identify which folders it should use and map to until someone tells it to list all folders (LIST) manually. Central part of the SPECIAL-USE idea was/is to require as little user interaction as possible to automatically setup a MUA to do the right thing. Speculating that probably most MUAs will do a LSUB by default and never will get to see SPECIAL-USE flags I think it is easier to have the server-side promote the flags. Do you think that would be possible? Just to verify I configured Dovecot as you would expect for SPECIAL-USE: I've set Dovecot 2.1 to autocreate and autosubscribe SPECIAL-USE mailboxes like this: namespace inbox { ... mailbox AltDrafts { special_use = \Drafts auto = subscribe } ... } This is what I get: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN AUTH=LOGIN AUTH=CRAM-MD5] Dovecot 2.1 ready. t1 login alice(a)example.com secret t1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS FUZZY SPECIAL-USE] Logged in t2 LSUB "" "%" * LSUB () "."

[Dovecot] compile dovecot-sieve for dovecot 1.2.9 (ubuntu pkg)

Cheers, I've a running Dovecot 1.2.9, installed from the ubuntu 10.04 Lucid LTS repository and trying to get the dovecot-sieve plugin (which seems to be not included in the lucid repo) compiled. Method 1 listed in http://wiki.dovecot.org/LDA/Sieve/Dovecot wont work, seems the rpm was build without --enable-header-install Is it sufficient to download the sources from http://archive.ubuntu.com/ubuntu/pool/main/d/dovecot/dovecot_1.2.9.orig.tar… and use them for ./configure --with-dovecot=$path ? thanks and happy holidays julien

[Dovecot] Can I block dovecot from deleting read messages, after being fetched?
by Vasiliu Adrian 21 Dec '11

21 Dec '11

Hi all, Is there an option to disable (server-side) the deletion of read mails after fetching them via POP3, regardless of the MUA config? Here are the issues I'm facing: - my boss wants to force everyone into a server-side "no delete message"-policy, for archiving, auditing and backup&recovery purposes - the requisite here is pop3, so imap is out - the mailusers are virtual users (held in a mysql db) - don't have the budget to set up a separate mail-arvhing server - don't want to use shaggy ways (aka immutable flag, r/w permissions for Maildirs, etc) dovecot --version 2.0.15 Help? Thanks!

After the imap_open() invocation, you should check for error messages in your PHP logs, or dump all the errors using imap_errors(); Without more details, I would say you dropped one of those /option-flags or got the mailbox argument syntax wrong.

[Dovecot] Mail lost - maybe a bug???
by Marco Carcano 21 Dec '11

21 Dec '11

Hello everybody I'm struggling against what seems a really serious trouble: sometimes mail get lost I did all the possible checks, but they seems really lost - I know is absurd, but it seems so it has been noticed by two users on my server: intially I tought that was their mistake (mail deleted, mail into spam, ecc), but it wasn't I deeply checked mail logs, and it seems that mail are delivered (the path is postfix->amavis->dovecotlda) - log files says that messages are delivered, but sometimes we lost a message. I also tried to get into the Maildir and grep the subject of the lost email: if it was addressed to more recipients I'm able to get it on some of them, but not to all (look at the example below) I hope I have clearly explained everything, otherwise let me knowmydomain now an extract from the log file: Oct 27 11:20:29 srv001 postfix/smtpd[24562]: connect from usstlz- psecap06.emerson.com[144.191.128.17] Oct 27 11:20:30 srv001 postfix/smtpd[24562]: CE0B74E4A9F: client=usstlz-psecap06.emerson.com[144.191.128.17] Oct 27 11:20:31 srv001 postfix/cleanup[25157]: CE0B74E4A9F: warning: header Subject: =?utf-8?B?

[Dovecot] APOP and AuthDatabase/SQL
by Peter Smith 21 Dec '11

21 Dec '11

Hi, We're running dovecot 1.2.15 and use SQL authentication. We'd like to be able to support APOP, but can't see how this would fit in with SQL auth. Currently we have: password_query = SELECT email as user, password FROM virtual_users WHERE email='%u' or (email LIKE '%n@%%' AND unhashed='%w') It seems that in order to auth APOP logins, we'd need to access variables containing the authentication string sent by the client, and also variables containing the auth string sent in the POP3 greeting. Incidentally, the RFC (1939) suggests using: <pid.time@hostname> for the greeting, but it looks as if dovecot uses something else? I'm seeing greetings such as: +OK Dovecot ready. <260f.4abcc.4ef11550.cJD6sQSUSnmPS1B/5RGF0Q==(a)myhostname.com> base64 encoding? Thanks in advance, Peter Smith
