[Dovecot] dovecot: imap-login: Disconnected (no auth attempts)
by J4K 09 Jan '12

09 Jan '12

Morning everyone, On the 8th of Jan the TLS/SSL certificate I use with Dovecot expired. I replaced it with a new on the 9th of Jan. I tested this with Thunderbird and all is well. This morning people tell me they cannot get their email using their mobile telephones : K9 Mail I have reverted the SSL cert back to the old one just in case. Thunderbird will works. Dovecot 1:1.2.15-7 running on Debian 6 The messages in the logs are: Jan 9 10:11:37 logout dovecot: imap-login: Disconnected (no auth attempts): rip=90.131.95.130, lip=88.119.95.13, TLS: Disconnected Jan 9 10:11:38 logout dovecot: imap-login: Disconnected (no auth attempts): rip=90.131.95.130, lip=88.119.95.13, TLS: Disconnected In dovecot.conf I have this set : disable_plaintext_auth = no And the auth default mechanisms are set to: mechanisms = plain login What is strange is the only item that changed is the SSL cert, which has since been changed back to the old one (which has expired... ^^). Any ideas where I may look or change? Regards, S

[Dovecot] Building 2.1.rc1 with cluence, but without libstemmer
by Jan Mikkelsen 08 Jan '12

08 Jan '12

Hi, I'm testing out 2.1.rc1, building against clucene 2.3.3.4. Without libstemmber, the build fails because it attempts to include SnowballAnalyzer.h which is not part of "core" clucene. Simple patch below to make dovecot 2.1.rc1 build with clucene but without libstemmer (or textcat). Looking at libstemmer itself, there are multiple versions. The version in clucene is put into libclucene-contribs-lib.so, but that version is older than libstemmer_c, which generates libstemmer.a, tested for in the dovecot 2.1.rc1 configure script. The dovecot code uses SnowballAnalyzer.h as a C++ wrapper around libstemmer. What versions of libstemmer, clucene and libtextcat is dovecot 2.1.rc1 intended to be used against? Is it worth bringing the wrapper class around libstemmer into dovecot to avoid funny dependencies against clucene and so that the -lstemmer test in configure is enough? For reference, I'm building on FreeBSD 9.0-RC3, system gcc. Regards, Jan Mikkelsen. diff -u -d -r dovecot-2.1.rc1/src/plugins/fts-lucene/lucene-wrapper.cc dovecot-2.1.rc1.patched/src/plugins/fts-lucene/lucene-wrapper.cc --- dovecot-2.1.rc1/src/plugins/fts-lucene/lucene-wrapper.cc 2011-11-09 08:45:26.000000000 +1100 +++ dovecot-2.1.rc1.patched/src/plugins/fts-lucene/lucene-wrapper.cc 2011-12-14 23:36:54.319796535 +1100 @@ -23,7 +23,9 @@ #include <CLucene.h> #include <CLucene/util/CLStreams.h> #include <CLucene/search/MultiPhraseQuery.h> +#if defined(HAVE_LUCENE_STEMMER) || defined(HAVE_LUCENE_TEXTCAT) #include "SnowballAnalyzer.h" +#endif /* Lucene's default is 10000.

[Dovecot] Possible mdbox corruption

I thought I had cleared out the corruption I had before - perhaps I was mistaken. What steps should I take to help locate these issues? Currently using 2.1rc1. I see the following errors in my logs, including out of memory and message size issues (at 15:30): Jan 4 05:17:17 bubba dovecot: indexer-worker(user1(a)domain.com): Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0(+0x3ed0a) [0x7f6e17cbfd0a] -> /usr/local/lib/dovecot/libdovecot.so.0(+0x3ed56) [0x7f6e17cbfd56] -> /usr/local/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f6e17c98d08] -> /usr/local/lib/dovecot/libdovecot.so.0(+0x4f310) [0x7f6e17cd0310] -> /usr/local/lib/dovecot/libdovecot.so.0(+0x3b965) [0x7f6e17cbc965] -> /usr/local/lib/dovecot/libdovecot.so.0(buffer_write+0x7c) [0x7f6e17cbd0ec] -> /usr/local/lib/dovecot/lib21_fts_solr_plugin.so(+0x3292) [0x7f6e164b7292] -> /usr/local/lib/dovecot/lib21_fts_solr_plugin.so(+0x3a97) [0x7f6e164b7a97] -> /usr/local/lib/dovecot/lib20_fts_plugin.so(fts_backend_update_set_build_key+0x2c) [0x7f6e166c4abc] -> /usr/local/lib/dovecot/lib20_fts_plugin.so(fts_build_mail+0x2d1) [0x7f6e166c5561] -> /usr/local/lib/dovecot/lib20_fts_plugin.so(+0xc630) [0x7f6e166ca630] -> dovecot/indexer-worker [user1(a)domain.com Sent -

[Dovecot] v2.1.rc2 released
by Timo Sirainen 06 Jan '12

06 Jan '12

http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc2.tar.gz http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc2.tar.gz.sig Lots of fixes since rc1. Some of the changes were larger than I wanted at RC stage, but they had to be done now.. Hopefully it's all over now, and we can have v2.1.0 soon. :) Some of the more important changes: * dsync was merged into doveadm. There is still "dsync" symlink pointing to "doveadm", which you can use the old way for now. The preferred ways to run dsync are "doveadm sync" (for old "dsync mirror") and "doveadm backup". + IMAP SPECIAL-USE extension to describe mailboxes + Added mailbox {} sections, which deprecate autocreate plugin + lib-fs: Added "mode" parameter to "posix" backend to specify mode for created files/dirs (for mail_attachment_dir). + inet_listener names are now used to figure out what type the socket is when useful. For example naming service auth { inet_listener } to auth-client vs. auth-userdb has different behavior. + Added pop3c (= POP3 client) storage backend. - LMTP proxying code was simplified, hopefully fixing its problems. - dsync: Don't remove user's subscriptions for subscriptions=no namespaces.

[Dovecot] ACL with IMAP proxying
by Alexis Lelion 06 Jan '12

06 Jan '12

Hello, I'm trying to use ACLs to restrict subscription on public mailboxes, but I went into trouble. My setup is made of two servers, and users are shared between them via a proxy. User authentication is done with LDAP, and credentials aren't shared between the mailservers. Instead, the proxies are using master password. The thing is that when the ACLs are checked, it actually doesn't give the user login, but the master login, which is useless. Is there a way to use the first part of destuser as it is done when fetching info from the userdb? Any help is appreciated, Thansk!

[Dovecot] doveadm + dsync merging
by Timo Sirainen 06 Jan '12

06 Jan '12

doveadm already supports some nice things, such as being able to remotely launch a doveadm command via TCP socket. It also supports executing a command for all users or to some specific users using a wildcard. dsync could use these features, so I merged dsync and doveadm into same binary for v2.1. I'll still install "dsync" symlink pointing to "doveadm", and running that way it should be fully backwards compatible with the old dsync binary and its parameters. I'm mainly now wondering about the command naming for running dsync via doveadm. Any suggestions? a) Use "doveadm dsync" prefix, and otherwise keep the names same: dsync mirror -> doveadm dsync mirror dsync backup -> doveadm dsync backup dsync server -> doveadm dsync server (for running dsync remotely via ssh/etc.) b) Don't have the dsync prefix: dsync mirror -> doveadm mirror dsync backup -> doveadm backup dsync server -> doveadm dsync-server (could be hidden from the doveadm commands list) c) Either a) or b), but rename "mirror" to "sync" or "dsync" or "replicate"? d) Something else?

[Dovecot] Small LOGIN_MAX_INBUF_SIZE for GSSAPI with samba4 (AD)
by Ludek Finstrle 04 Jan '12

04 Jan '12

Hello, I faced the problem with samba (AD) + mutt (gssapi) + dovecot (imap). From dovecot log: Jan 2 17:58:42 server dovecot: imap-login: Disconnected: Input buffer full (no auth attempts): rip=192.167.14.16, lip=192.167.14.16, secured My situation: CentOS 6.2 IMAP: dovecot --version: 2.0.9 (CentOS 6.2) MUA: mutt 1.5.20 (CentOS 6.2) Kerberos: samba4 4.0.0alpha17 as AD PDC $ klist -e Ticket cache: FILE:/tmp/krb5cc_1002_Mmg2Rc Default principal: luf@TEST Valid starting Expires Service principal 01/02/12 15:56:16 01/03/12 01:56:16 krbtgt/TEST@TEST renew until 01/03/12 01:56:16, Etype (skey, tkt): arcfour-hmac, arcfour-hmac 01/02/12 16:33:19 01/03/12 01:56:16 imap/server.test@TEST Etype (skey, tkt): arcfour-hmac, arcfour-hmac I fixed this problem with enlarging LOGIN_MAX_INBUF_SIZE. I also red about wrong lower/uppercase but it's not definitely my problem (I tried all possibilities of lower/uppercas in login). I sniffed the plain communication and the "a0000 AUTHENTICATE GSSAPI" line has around 1873 chars. When I enlarged the LOGIN_MAX_INBUF_SIZE to 2048 the problem disappeared and I'm now able to login to dovecot using gssapi in mutt client. I use also thunderbird (on windows with sspi) and it works ok with LOGIN_MAX_INBUF_SIZE = 1024. Does anybody have any idea why it's so large or how to fix it another way? It's terrible to patch each version of dovecot rpm package. Or is there any possibility to change constant? I have no idea how much this should affect memory usage. The simple patch I have to use is attached. Please cc: to me (luf at pzkagis dot cz) as I'm not member of the this list. Best regards, Ludek Finstrle

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 }

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:?
by Ralf Hildebrandt 03 Jan '12

03 Jan '12

For archiving purposes I'm delivering all addresses to the same mdbox: like this: passdb { driver = passwd-file args = username_format=%u /etc/dovecot/passwd } userdb { driver = static args = uid=1000 gid=1000 home=/home/copymail allow_all_users=yes } Yet I'm getting this: Jan 3 19:03:27 mail postfix/lmtp[29378]: 3THjg02wfWzFvmL: to=<firstname.lastname@charite.de@backup.invalid>, relay=mail.charite.de[private/dovecot-lmtp], conn_use=20, delay=323, delays=323/0/0/0, dsn=4.1.1, status=SOFTBOUNCE (host mail.charite.de[private/dovecot-lmtp] said: 550 5.1.1 <"firstname.lastname(a)charite.de"@backup.invalid> User doesn't exist: "firstname.lastname(a)charite.de"@backup.invalid (in reply to RCPT TO command)) (using soft_bounce = yes here in Postfix) In short: backup.invalid is delivered to dovecot by means of LMTP (local socket). I thought my static mapping in userdb would enable the lmtp listener to accept ALL recipients and map their $home to /home/copymail - why is that not working? -- 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] 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] What is normal CPU usage of dovecot imap?
by Mikko Lampikoski 03 Jan '12

03 Jan '12

I got Dual Core Intel Xeon CPU 3.00GHz, over 1000 mailbox and almost 1 dovecot login / second (peak time). Server stats says that load is continually over 2 and cpu usage is 60%. top says that imap is making this load. virtual users are in mysql database and mysqld is running on another server (this server is ok). Do I need better CPU or is there something going on that I do not understand? # dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-4-pve i686 Ubuntu 9.10 nfs log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s listen: *, [::] ssl_ca_file: /etc/ssl/**********.crt ssl_cert_file: /etc/ssl/**********.crt ssl_key_file: /etc/ssl/**********.key ssl_key_password: ********** disable_plaintext_auth: no verbose_ssl: yes shutdown_clients: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no login_process_size: 128 login_processes_count: 10 login_max_processes_count: 2048 mail_max_userip_connections(default): 10 mail_max_userip_connections(imap): 10 mail_max_userip_connections(pop3): 3 first_valid_uid: 99 last_valid_uid: 100 mail_privileged_group: mail mail_location: maildir:/var/vmail/%d/%n:INDEX=/var/indexes/%d/%n fsync_disable: yes mail_nfs_storage: yes mbox_write_locks: fcntl mbox_min_index_size: 4 mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_process_size: 2048 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds(default): outlook-idle imap_client_workarounds(imap): outlook-idle imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls auth default: mechanisms: plain login cram-md5 cache_size: 1024 passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=99 gid=99 home=/var/vmail/%d/%n allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth-client mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail

[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 ?
by Jan-Frode Myklebust 03 Jan '12

03 Jan '12

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
