[Dovecot] Dovecot under Virtual Host environment??
by sparkietm 10 Jan '12

10 Jan '12

Hi all, Could anyone point me to a walk-through of setting up Dovecot for multiple domains under a Virtual Host environment? I'd like to offer clients their own email domain for each virtual host e.g john(a)client_1.com, sue(a)client_2.com. I'm guessing this is fairly common set-up, but a search on "multiple domains" didn't bring much back. Also, would it be possible to offer each client webmail? Many thanks in advance Mark -- View this message in context: http://old.nabble.com/Dovecot-under-Virtual-Host-environment---tp33114381p3… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] A small bug and a question about CONTEXT=SEARCH
by Anders 10 Jan '12

10 Jan '12

Hi, I have been looking at search and sorting with dovecot and have run into some things. The first one I think may be a minor bug because a set of commands result in the socket connection being closed without warning: UID SEARCH RETURN (SAVE COUNT) CHARSET UTF-8 (UNDELETED TEXT "foo") UID SEARCH RETURN (COUNT MIN) CHARSET UTF-8 () $ The empty paranthesis before the reference to the previous search result ($) is not legal IMAP, but should not cause the socket to be closed I think. Then I have question about RFC5267 and the announcement of CONTEXT=SEARCH in the capabilities. I think this RFC is supported by dovecot, or maybe just part of the RFC is supported? At least when I include the CONTEXT ADDTO or REMOVEFROM keywords I get an error, but UPDATE and CANCELUPDATE seem to be supported. The RFC has been updated by the RFC describing the NOTIFY extension to IMAP so maybe it has been decided to not add these keywords until a later time? I am using dovecot version 2.0.15 (with patches from Apple). Best Regards Anders

[Dovecot] rewriting mail_location
by Burckhard Schmidt 10 Jan '12

10 Jan '12

Hello, I have LDAP as userdb. Entries containing attributes mail=alias.user1(a)some.domain.de and uid=user1 Mail to alias.user1(a)some.domain.de gets delivered into /datatest/user/alias.user1 instead of /datatest/user/user1 by lda. I have userdb { args = /usr/dovecot/etc/ldapuser.conf driver = ldap } with a ldapuser.conf: hosts ... base ... user_filter = (&(|(mail=%u)(mail=%n(a)some.domain) (uid=%u))(objectClass=posixAccount)) user_attrs = uid=mail_location=maildir:/datatest/user/%$, uidNumber=29,gidNumber=133 I hoped local part of attribute mail could be replaced by uid for local delivery with dovecots lda? Any hints how to do that? (With postfix I could rewrite the address to uid@host and use local_transport = dovecot.) postfix has virtual_transport = dovecot.

[Dovecot] Proxy login failures

Hi, I'm using two dovecot pop3/imap proxies in front of our dovecot servers. Since some days I see many of the following errors in the logs of the two proxy-servers: ... dovecot: pop3-login: Error: proxy: Remote "IPV6-IP":110 disconnected: Connection closed: Connection reset by peer (state=0): user=<myuser>, method=PLAIN, rip=remote-ip, lip=localip ... dovecot: imap-login: Error: proxy: Remote "IPV6-IP":143 disconnected: Connection closed: Connection reset by peer (state=0): user=<myuser>, method=PLAIN, rip=remote-ip, lip=localip ...

[Dovecot] Postfix user map
by Timo Sirainen 10 Jan '12

10 Jan '12

http://hg.dovecot.org/dovecot-2.1/rev/f562bcaca215 implements "postmap" type sockets, which follow Postfix's tcp_table(5) protocol. So you can ask: get user@domain and Dovecot answers one of: - 200 1 - 500 User not found - 400 Internal failure So you can use this with Postfix: virtual_mailbox_maps = tcp:127.0.0.1:1234 With Dovecot you can enable it with: service auth { inet_listener postmap { listen = 127.0.0.1 port = 1234 } } Anyone have ideas if this could be improved, or used for some other purposes?

[Dovecot] change initial permissions on creation of mail folder
by mailinglist 09 Jan '12

09 Jan '12

Installed dovcot from Debian .deb file. Creating a new account for system users sets permission for user-only. Where to change initial permissions on creation of mail folder and other subdirectories. Installed dovecot using "apt-get install dovecot-imapd dovecot-pop3d". Any time when I create a new account in my mail client for a system user, Dovecot tries to create ~/mail/.imap/INBOX. The permissions for mail and .imap are set to 0700. By this permissions INBOX can not be created leading to an error message in log files. When I manualy change the permissions to 0770, INBOX is created

[Dovecot] failed: Too many levels of symbolic links
by David Egbert 09 Jan '12

09 Jan '12

All, My dovecot install works great except for one error I keep seeing this in my logs. The folder has 7138 messages in it. I am informed the user they needed to reduce the number of messages in the folder and believe this will fix the problem. My question is about where the problem lies. Is the problem related to an internal limit with Dovecot v2.0.15 or with my Debian (3.1.0-1-amd64)?

Re: [Dovecot] Newbie: LDA Isn't Logging
by Michael Papet 09 Jan '12

09 Jan '12

I did some testing on a Debian testing VM. I built 2.0.17 from sources and copied the config straight over from the malfunctioning machine. LDA logging worked. So, it could be something about my system. But, running /usr/lib/dovecot/deliver still doesn't return a value on the command line as documented on the wiki. I've attached strace files from both the malfunctioning Debian packages machine and the built from sources VM. Unfortunately, I'm a new strace user, so I don't know what it all means.

[Dovecot] Resetting a UID
by Tom Clark 09 Jan '12

09 Jan '12

Hi, We've got a client with a Blackberry that hass deleted his emails off his Blackberry device. The BES won't re-download the messages as it believes it has already downloaded them (apparently it matches on UID). Is there any way of resetting a folder (and messages in the folder) UID? I know in courier you used to be able to touch the directory. Thanks, Tom Clark

[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] 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

[Dovecot] error bad file number with compressed mbox files

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! The relevant part of the dovcot configuration is: # 2.0.16: /opt/local/etc/dovecot/dovecot.conf # OS: SunOS 5.10 sun4v mail_fsync = always mail_location = mbox:~/Mail:INBOX=/var/mail/%u mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = mail_log notify zlib mmap_disable = yes Thank you, -- Jürgen Obermann Hochschulrechenzentrum der Justus-Liebig-Universität Gießen Heinrich-Buff-Ring 44 Tel. 0641-9913054

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

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).

[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

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?
by Asheesh Laroia 29 Dec '11

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

[Dovecot] Sieve too rfc compliant ;-)
by Jan-Frode Myklebust 20 Dec '11

20 Dec '11

It seems we have a few email addresses that are not RFC 5322 compliant, and now that we've started using sieve these are failing. The problem is that we have a few addresses with leading, trailing or double dots in the local part: jan..frode(a)tanso.net .janfrode(a)tanso.net janfrode.(a)tanso.net I believe these has been working fine with everything else in dovecot (lda, lmtp, imap, pop), but that sieve is more strict. I think it's fair enough that it's strict with messages generated by sieve scripts, but it would be nice if it could be more tolerant with messages addressed for the sieve script. So, is there any setting for making it more tolerant ? -jf

I have tried with doveadm force-resync, maybe this could solve this issues. All of those should be fixed automatically. Do they keep happening if you don't do force-resync? How often do they happen anyway? Do they happen at any specific times (e.g. during doveadm purge)?

Hi, I'm strugling to find some documentation on dovecot's anvil service and/or its penalties (that can be checked with doveadm penalty) ... but i'm not finding anything on that. is there any documentation on anvil/penalties that i should check other than a few messages on the mailing list archive ? thanks ! -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

[Dovecot] Dovecot 2.1rc1 + 2.0.16 woes regarding fts_squat
by Robin 20 Dec '11

20 Dec '11

I can confirm the report posted in http://dovecot.org/list/dovecot/2011-November/062263.html that fts_squat no longer seems to be used after moving from 2.0.16->2.1 rc 1. I don't see crash reports in the logs, just "0 messages indexed". My search test tool just does a normal IMAP SEARCH for a long non-existent string. If there's another way to trigger re-indexing in 2.1, I don't see anything in the documentation for it. I've enabled mail_debug, but no log entries that shed light on the problem are available. Has the configuration for fts_squat changed? If anyone has a working fts_squat setup with Dovecot 2.1rc1, I'd appreciate hearing how you have it setup and working. During a large mail import with 2.0.16 today, I ran across a worrying message in the logs during an fts_squat reindex: out of memory. The plugin doesn't obey the mmap_disable configuration directive, which I've confirmed in the plugin source. The mailbox in question has only 17GB (mdbox style), with about 90,000 emails in it. Its "index" (for the purposes of normal IMAP retrieval as opposed to IMAP TEXT/BODY searching) is fine and uncorrupted. I freshly import these mailboxes between test iterations and any version changes anyway, so if there's corruption, it's happening within dovecot only. I'm using use Mail::IMAPClient to create + append mail over localhost, not any direct mdbox conversion trickery. In looking through the code, I see that mmap() is called for the *ENTIRE FILE*, which is guaranteed to fail on large indexes. I assume this was done out of expedience, but it's a "risky" sort of thing to do in a server process, even if 8GB RAM systems do seem to grow on trees.

[Dovecot] Question about index reset in dovecot 2.0.15

[Dovecot] doveadm quota does not list all accounts
by Nikolaos Milas 20 Dec '11

20 Dec '11

Hello, I am running dovecot-2.0.13-1_128.el5 x86_64 RPM on CentOS 5.7. All accounts are virtual, hosted on LDAP Server. My problem is that the command: doveadm quota get -A stopped listing all accounts. I think this problem started after I changed in LDAP lookup configuration from "scope = subtree" to "scope = onelevel", because it did not occur before (I did no other changes). Now, the above command only lists 12 accounts. If I query for a particular user: doveadm quota get -u userx this works fine, but userx (and all users except those 12) is NOT listed when trying to display all users. How can I run the above command without problems again? Thanks in advance, Nick

[Dovecot] Quota PostgreSQL INSERT trigger
by Adis Nezirovic 20 Dec '11

20 Dec '11

Wiki instructions for creating insert trigger for PostgreSQL are wrong http://wiki.dovecot.org/Quota/Dict Calling INSERT on the table from within BEFORE INSERT trigger creates cascading trigger. http://www.postgresql.org/docs/current/interactive/trigger-definition.html Instead, one should return NEW record from the trigger, and it will be inserted after trigger execution. --- CREATE OR REPLACE FUNCTION merge_quota2() RETURNS TRIGGER AS $$ BEGIN IF NEW.messages < 0 OR NEW.messages IS NULL THEN -- ugly kludge: we came here from this function, really do try to insert IF NEW.messages IS NULL THEN NEW.messages = 0; ELSE NEW.messages = -NEW.messages; END IF; return NEW; END IF; LOOP UPDATE quota2 SET bytes = bytes + NEW.bytes, messages = messages + NEW.messages WHERE username = NEW.username; IF found THEN RETURN NULL; END IF; BEGIN IF NEW.messages = 0 THEN RETURN NEW; ELSE NEW.messages = - NEW.messages; RETURN NEW; END IF; EXCEPTION WHEN unique_violation THEN -- someone just inserted the record, update it END; END LOOP; END; $$ LANGUAGE plpgsql; DROP TRIGGER IF EXISTS mergequota2 ON quota2; CREATE TRIGGER mergequota2 BEFORE INSERT ON quota2 FOR EACH ROW EXECUTE PROCEDURE merge_quota2(); --- Best regards, Adis

[Dovecot] Tuning Login processes for High-performance Mode
by Alessio Cecchi 20 Dec '11

20 Dec '11

Hi, I'm working for tuning a busy cluster of dovecot servers. Heach server as 4 core, 8GB of RAM and provide POP3 and IMAP access to mailbox. OS is Debian 6.0 and dovecot version is 1.2.15. I am unsure how to set "login_max_processes_count" and "login_max_connections" for reach the best situation when login_process_per_connection is set to no. I don't know what value to set login_max_processes_count. For example is better the first or the second configuration? login_process_per_connection=no login_processes_count=4 login_max_processes_count=8 login_max_connections=512 login_process_size=128 login_process_per_connection=no login_processes_count=4 login_max_processes_count=16 login_max_connections=256 login_process_size=128 Which is a suggested ratio from login_max_processes_count and login_max_connections ? Other values are correct?

[Dovecot] Calculation of suggested vsz_limit values
by Nikolaos Milas 20 Dec '11

20 Dec '11

Hello, I would like to ask on suggested vsz_limit values. Is there any way of calculating such values? How should we determine them? I don't want to risk wrong values (and possible errors) on a production system, if I upgrade to 2.0.16 where vsz_limit values are enforced (I read release notes)! If there is no standard way of calculation, could someone please check the following info and suggest some values? I am running dovecot-2.0.13-1_128.el5 x86_64 RPM on CentOS 5.7 (as a VM on a KVM Host). All accounts are virtual, hosted on LDAP Server. We have about 250 mailboxes of 4GB each (in practice, only a couple of mailboxes ever reach 1GB so we are "over-booking"). It is a relatively low-load server. Memory status and config follows below.

[Dovecot] Strange Login / Timeout Sessions
by Carlos Mennens 20 Dec '11

20 Dec '11

I have my webmail application tied to Postfix / Dovecot server & now for some reason the IMAP sessions oddly time out throughout the day and then logging back into the mail system over the web is painfully slow. The only thing I've seen that fixes it is to reload the Dovecot daemon in Linux: /etc/init.d/dovecot reload Once that command is ran, my webmail login is super fast and moving from folder to folder is extremely fast again. Then in about a few hours, the session will time out and this problem repeats. The problem is the same for everyone and not just a few user accounts. Anyone have any idea what I should be looking for or looking at? My Dovecot logs or mixed in /var/log/maillog which is extremely hard to watch live & gets mixed with Postfix, Amavisd, and Postgrey. Any ideas or suggestions to narrow this problem out? I'm running Dovecot-1.0.7-7.el5_7.1. I saw this load on the console today: Error: Dovecot is already running with PID 2334 (read from /var/run/dovecot/master.pid) Fatal: Invalid configuration in /etc/dovecot.conf Below is my configuration file: [root@mail ~]# dovecot -n # 1.0.7: /etc/dovecot.conf protocols: imap ssl_ca_file: /etc/ssl/certs/digicert.crt ssl_cert_file: ***OMIT*** ssl_key_file: ***OMIT*** login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: maildir:~/Maildir auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix

[Dovecot] Two important new Pigeonhole v0.3 features
by Stephan Bosch 19 Dec '11

19 Dec '11

Hello Dovecot users, Pigeonhole v0.3 for Dovecot v2.1 has two new features I would like you to play with before I make a first release: 1) The new Sieve editheader extension (http://tools.ietf.org/html/rfc5293) This allows modifying the headers of the message before delivery. This is actually the first implemented extension that can modify the message itself in any way. This feature adds quite a bit of new code that I'd like to see tested more thoroughly. 2) The new sieve-filter tool (documented in the sieve-filter(1) man page upon installation). This allows (re-)filtering messages that are already stored in a particular mailbox. It preserves the assigned IMAP flags and keywords and using the imap4flags extension these can also be modified. It also plays nice with the editheader extension. Judging by postings in this mailing list from the last few years, this is a highly-demanded feature and I'm glad that I finally got around to finish this thing. If the new sieve-filter tool is lacking certain features in your opinion, just let me know. Needless to say: read the man page carefully and watch out with important mail. This is currently only available from the mercurial repository, but if you prefer to have an .rc1 release first, just tell me and I'll make one. The automatic Debian repository already includes these features. Regards, Stephan.

[Dovecot] IMAP and sieve
by moozer 19 Dec '11

19 Dec '11

I am currently setting up an IMAP server for archiving purposes. The goal is to drag an email to the IMAP folder, and then have a server-side sieve script to put it in the right folder. One of the sources used was this wiki entry http://wiki.dovecot.org/LDA/Sieve/Dovecot I added the mail_plugins = sieve to /etc/dovecot/15-lda.conf and after some exim4 fiddling, mails delivered are filtered by my sieve script. Doing the same for imap delivery (in /etc/dovecot/20-imap.conf) give the following error Dec 19 10:22:09 leon dovecot: imap: Error: dlopen(/usr/lib/dovecot/modules/lib90_sieve_plugin.so) failed: /usr/lib/dovecot/libdovecot-sieve.so.0: undefined symbol: mail_deliver_save_open Dec 19 10:22:09 leon dovecot: imap: Error: Can't load plugin sieve_plugin: Plugin is intended to be used only by binaries: lda lmtp (we're imap) Dec 19 10:22:09 leon dovecot: imap: Fatal: Couldn't load required plugins Dec 19 10:22:10 leon dovecot: imap: Error: dlopen(/usr/lib/dovecot/modules/lib90_sieve_plugin.so) failed: /usr/lib/dovecot/libdovecot-sieve.so.0: undefined symbol: mail_deliver_save_open Dec 19 10:22:10 leon dovecot: imap: Error: Can't load plugin sieve_plugin: Plugin is intended to be used only by binaries: lda lmtp (we're imap) Dec 19 10:22:10 leon dovecot: imap: Fatal: Couldn't load required plugins I notice this part: "plugin is intended to be used only by binaries: lda lmtp (we're imap)" So the question is if it is possible to run sieve server-side sieve scripts on emails copied using IMAP. Suggestions are most welcome. Moozer -- I am running debian testing # dovecot --version 2.0.15

[Dovecot] DKIM Verification failures
by Nikolaos Milas 18 Dec '11

18 Dec '11

Hi, -- This message refers to the maillist itself rather than to dovecot software -- I have noticed that when I post to this list (only), I get DKIM Verification failure reports from: root(a)moncton.sidefx.com (e.g. for my last post: "DKIM failure report for job 4D27B5DC4E on mail.sidefx.com") root(a)mail.rmacd.com (e.g. for my last post: "DKIM failure report for job B69B3187F1 on mail.rmacd.com") root(a)mx0.roessner-net.de (e.g. for my last post: "DKIM failure report for job 6103B52092 on mx0.roessner-net.de") I have not had other DKIM failure reports from anywhere and I know that we should not have issues with it. An example from gmail: Authentication-Results: mx.google.com; spf=pass (google.com: best guess record for domain of nmilas(a)noa.gr designates 195.251.204.235 as permitted sender) smtp.mail=nmilas(a)noa.gr; dkim=pass header.i=(a)noa.gr So, whom should I contact to investigate this problem?

[Dovecot] simultaneous scripts not running via sieve_before
by Scott Lewis 16 Dec '11

16 Dec '11

Hi again everyone, So I've finally got sieve integration happening on my REHL Postfix/Dovecot server, with private user scripts happily running when users create them. (we user SquirrelMail, so the avelsieve plugin runs the sieve integration). Now I'd like to utilise additional per-user scripts (probably via sieve_before), but I've not been able to get my additional scripts to execute. I am doing the following: a) getting avelsieve to write my redirect script (ie. logging on as user, completing private script wizard, and activating it) b) compiling .dovecot.sieve with sievec c) copying the resultant .dovecot.svbin to sieve/ directory (and renaming it eg redirect.svbin still, it appears that each /home/%u/.dovecot.sieve file is the only one taking effect. Any thoughts on how to make the other ones active? (The idea behind this is to automatically forward all of joeuser@mydomain's incoming mail to somewhere like joeusersbackup(a)gmail.com, for backup reasons. One day, I'll work out how to configure postfix to do this for all outgoing email too, but that's for another day :) Below are what my .conf files look like. Thanks in advance, Scott /etc/dovecot.conf: [code] protocols = imap imaps managesieve listen = * protocol imap { #mail_plugins = sieve quota } ## ## ManageSieve specific settings ## protocol managesieve { # debugging mail_debug = yes #login_executable = /usr/libexec/dovecot/managesieve-login #mail_executable = /usr/libexec/dovecot/managesieve #managesieve_max_line_length = 65536 #managesieve_logout_format = bytes ( in=%i : out=%o ) #managesieve_implementation_string = Cyrus timsieved v2.2.13 } protocol lda { mail_plugins = sieve quota sieve=~/.dovecot.sieve sieve_extentions = +include sieve_dir=~/sieve sieve_before = /home/%u/sieve/redirect.svbin sieve_global_path = /etc/globalsieverc.svbin [/code]

I'm trying to get the pipe backend to work with the new dovecot-antispam (I was very pleased to see the new version, thanks Johannes!)

[Dovecot] Two recent issues
by Brad Schuetz 14 Dec '11

14 Dec '11

I've been using dovecot for years, been working great. However recently I've come across two issues. The first issue unfortunately I have little information on, mail_debug hasn't provided anything useful either (in fact it looks like the login request that fails doesn't even get logged at all). During the morning rush of email, this server has around 11k mailboxes on it, it *appears* that one of the auth processes dies resulting in "dovecot: imap-login: Error: read(imap) failed: Connection reset by peer" errors followed by "dovecot: imap-login: Internal login failure ..." in the logs. I've yet to get any useful debugging information on this error so I'm not expecting much/any help on this one, but if anyone has any ideas on how I can get more debug besides running strace 24/7 in the hopes it catches something before the hard drive is full of strace output I'd love to hear it. The best I've gotten was a lucky strace once (at the time I didn't realize it was so lucky or I would have saved the output) that indicated the imap-login daemon was failing to connect to the auth process. The second issue is lmtp/lda (tried both) delivery to a mailbox that has filesystem quotas enabled and the group quota is maxed is resulting in the below panic and crash. This issue happens with 2.0.13, 2.0.15 and 2.0.16. Here's the logs showing that it knows the disk quota is exceeded and then a subsequent zlib panic. Like it's trying to deliver it anyway. --------------------- 11:21:07 [err] dovecot: lmtp(29691, admin(a)[redacted].com) Error: o_stream_send_istream(/email/d/r/[redacted]/[redacted]/admin/Maildir/tmp/1323458467.M245978P29691.fenrir.omnis.com) failed: Disk quota exceeded 11:21:07 [crit] dovecot: lmtp(29691, admin(a)[redacted].com) Panic: file ostream-zlib.c: line 144 (o_stream_zlib_send_flush): assertion failed: (zs->avail_in == 0) 11:21:07 [err] dovecot: lmtp(29691, admin(a)[redacted].com) Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0 [0x345443ca90] -> /usr/lib64/dovecot/libdovecot.so.0 [0x345443cae6] -> /usr/lib64/dovecot/libdovecot.so.0 [0x345443c4a3] -> /usr/lib64/dovecot/lib20_zlib_plugin.so [0x2ba2d31547f6] -> /usr/lib64/dovecot/lib20_zlib_plugin.so [0x2ba2d315481b] -> /usr/lib64/dovecot/libdovecot.so.0(o_stream_flush+0x2a) [0x345444f0ea] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maildir_save_finish+0x6b) [0x3451c63b6b] -> /usr/lib64/dovecot/lib10_quota_plugin.so [0x2ba2d2f4ce7a] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_save_finish+0x30) [0x3451c2fbb0] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_storage_copy+0xb3) [0x3451c2aae3] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maildir_copy+0x56) [0x3451c6fd36] -> /usr/lib64/dovecot/lib10_quota_plugin.so [0x2ba2d2f4d0ba] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_copy+0x5a) [0x3451c301ba] -> /usr/lib64/dovecot/li 11:21:07 [err] dovecot: master: Error: service(lmtp): child 29691 killed with signal 6 (core dumps disabled) --------------------- Attached is the current "doveadm config" output. -- Brad Schuetz

Re: [Dovecot] Questions about single intance storage

Hello Timo. If we can not safely restore from backup a user's mailbox with SiS enabled, we can not enable SiS. Any plan to include this backup recovery tool in dovecot 2.0.X or 2.1? Regards Maria > 5º We use bacula to save indexes & mdboxes, and we recover mailboxes using doveadm import when a user "makes a fatal mistake" wiping all her Inbox. If we enable SiS I am not really sure how can we safely restore a user's INBOX if that user has SiS attachments. Hm. Yes, that is problematic.. Even if you knew what SIS files were used, there's no simple way to restore those with proper refcounts. I think what really should be done is writing a tool that can create/restore backups, possibly de-SISing the attachments..

[Dovecot] Saving archive copy of all mail sent/received w/Dovecot+Postfix?
by Andrew M 12 Dec '11

12 Dec '11

I'm running Dovecot 2.0.15 and Postfix 2.7.7 with postfix handing off to Dovecot's LDA. I am hosting multiple virtual domains with multiple users and everything is working. I would now like to create a permanent archive of all sent/received mail with each virtual user's mail saved to its own sent file and received file. This needs to be independent of the user's regular Maildir store since he can't delete or modify the permanent archive. Any suggestions on how to best accomplish this either via postfix or dovecot? Postfix has in main.cf virtual_transport = dovecot and in master.cf dovecot unix - n n - - pipe flags=DRhu user=virtual:virtual argv=/usr/libexec/dovecot /dovecot-lda -d ${recipient} -f ${sender} dovecot uses this: [root@xxx andrew]# dovecot -n # 2.0.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.35.14-103.fc14.x86_64 x86_64 Fedora release 14 (Laughlin) ext4 auth_mechanisms = plain login cram-md5 disable_plaintext_auth = no mail_location = maildir:/home/vmail/%d/%n/Maildir mbox_write_locks = fcntl passdb { args = scheme=plain username_format=%u /etc/postfix/passwd driver = passwd-file } protocols = imap lmtp service auth { inet_listener { port = 12345 } unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { mode = 0666 } } ssl_cert = </etc/pki/tls/certs/xxx.com.crt ssl_key = </etc/pki/tls/private/xxx.com.key userdb { args = username_format=%u uid=5000 gid=5000 home=/home/vmail/%d/%n driver = static } Thanks, Andrew

[Dovecot] mail_max_userip_connections=10
by Tom Clark 12 Dec '11

12 Dec '11

Hi, A couple of questions rather than a problem for once! We've got our Dovecot server running smoothly now apart from our MD. He's having problems with mail_max_userip_connections. He has 3 (Phone/Laptop/Tablet) items that all connect to the server at about the same time. Which means he's frequently running over the max_userip_connections. My questions are: Is there anyway of whitelisting an IP so that it can ignore mail_max_userip_connections=10? What should we set mail_max_userip_connections too realistically? 10 seems a bit low? Thanks Tom

[Dovecot] question regarding postfixadmin
by oni-neko＠gmx.net 12 Dec '11

12 Dec '11

Hello! I hope someone here is already using postfixadmin with dovecot and can help me out =) the install-readme for postfixadmin mentions, that the mail-home should be set to default_mail_env = maildir:/var/mail/vmail/%u/ but my dovecot is already installed and working with another config, namely mail_location = maildir:/var/dovecotmail/%n/Maildir. Do i have to change this, or is postfixadmin able to read this or can i set this value in postfixadmin somewhere? i´d rather avoid moving all mailfolders around just because of that, and unfortunately the paths don´t really lend themself to an easy solution via symlink ^_^ thanks for any replies best regards sil -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de

[Dovecot] Documentation clarifiction on mmap_disable

Greetings, On http://wiki.dovecot.org/MainConfig I read: "mmap_disable = no Don't use mmap() at all. This is required if you store indexes to shared filesystems (NFS or clustered filesystem). " Does that mean: 1. mmap is required when using NFS or 2. it is required to don't use mmap at all when using NFS? Sorry if this is obvious. Best regards. -- *Marcio Merlone*

[Dovecot] database failover
by Nick Edwards 12 Dec '11

12 Dec '11

Trying to get dovecot to _only_ use local copy of database, only querying another database server (same database, just replicated) if local copy is not responding, I have google fu'd a bit and found my only answer in so far as dovecot did this once upon as time, but it was only due to a dovecot bug, that has since been fixed, is that so? The wiki shows no information of failover, just load sharing, or is it an undocumented feature, or can dovecot not do failover, if not, can it be made so? Trying to cut down on network traffic, postfix does this nicely, I thought dovecot did too.

With 2.0.16 hdr.xxx fields get copied fine (but of course without timestamp). With the patch you provided they don't get copied whether using mirror or backup & starting from scratch. I'm doing a Maildir to sdbox migration otherwise don't think I'm doing anytihng strange. Mark ________________________________________ From: Mark Zealey Sent: 08 December 2011 09:35 To: Timo Sirainen Cc: Dovecot Mailing List Subject: RE: [Dovecot] using dsync to convert mailboxes looses caching options OK I'll test the header copying more fully. The reason we want to preserve caching decisions is to avoid an IO storm when users log in to their mailboxes after an sdbox upgrade so it would be great to be able to have some way to warm caches.

[Dovecot] using dsync to convert mailboxes looses caching options
by Mark Zealey 10 Dec '11

10 Dec '11

Hi there, We're trying to convert users from Maildir to sdbox at present; I'm using dsync to achieve this (2.0.16) however when the user's have been converted we only get minimal information in the caching files. Is there some way to preserve all the caching decisions that were previously made so that when the user logs in to the new mailbox we don't have to cause an io storm rebuilding the cache that we know was good? Dovecot seems to be partially doing this - if i remove the logs/cache from the source mailbox no cache files are built in the conversion; if i put them back then we get a cache file built but it only contains a few bits of information (guid, date.save). Looking into this a bit further i find that when the caches are present at source the fields are preserved but the 'last used' date and caching decisions are not which I suspect means dsync doesn't bother caching on import - only fields with a yes decision in the source are copied (but their decision is only copied as a tmp with the date of import). For example: Source idxview cache: -- Cache fields -- # Name Type Size Dec Last used 0: flags bit 4 tmp 2011-11-25 16:09 1: date.received fix 4 yes 2011-11-26 16:17 2: size.virtual fix 8 tmp 2011-11-25 16:09 3: imap.bodystructure str - tmp 2011-11-25 16:09 4: mime.parts var - tmp 2011-11-25 16:09 5: hdr.IMPORTANCE hdr - tmp 2011-11-25 16:09 6: hdr.X-PRIORITY hdr - tmp 2011-11-25 16:09 7: hdr.CONTENT-TYPE hdr - tmp 2011-11-25 16:09 ... 18: date.sent fix 8 no 1970-01-01 01:00 19: date.save fix 4 yes 2011-11-26 16:17 20: size.physical fix 8 no 1970-01-01 01:00 21: imap.body str - no 1970-01-01 01:00 ...

[Dovecot] POP - preventing re-download with server move
by Trutwin, Joshua 10 Dec '11

10 Dec '11

Hi, Curious if anyone has any good suggestions to handle this. I try to get my hosting users to use IMAP but most use Outhouse and the IMAP support is somewhat annoying for many so I typically have them change their settings when using POP to leave copies on the server. That way when they get the inevitable virus or wanna use webmail they have a backup copy and webmail sees their saved mail. So now I have to move my sites to a new server and I'm trying to avoid having all these messages re-downloaded by POP clients. Some of the sites I've moved with low email usage have just dealt with the re-download and cleaned up afterwards. I have a few other accounts though that I'm more concerned about that have massive amounts of stored email. The mail is stored in Maildirs - a sample file: 1280409166.23580.foo:2,S If I move this to server "bar" would renaming the file to 1280409166.23580.bar:2,S prevent this somehow? Old server uses qmail-pop, new server uses dovecot 2.0. Thanks for any tips, Josh

[Dovecot] noaclright
by Knud Dombrowsky 10 Dec '11

10 Dec '11

Hi, I recently upgraded to openSuse 12.1 which comes with dovecot 2.0.14. Because of mail-client-problems I am running one dovecot which requires authentication via a client-certificate and another one which can be used without a certificate. (Configurations can be found below.) Since the upgrade our shared mailbox is no longer visible. I tried to repair this by setting the ACLs once again (using imap-acl in Thunderbird) but every time I try to set a new ACL the tool says "noaclright" and dovecot logs the following messages: Dec 7 14:31:14 mailbox dovecot: imap(<sharing-user>): Error: fstat(/home/<sharing-user>/Maildir/.<shared-folder>/dovecot-acl.lock) failed: No such file or directory Dec 7 14:31:14 mailbox dovecot: imap(<sharing-user>): Error: file_dotlock_open(/home/<sharing-user>/Maildir/.<shared-folder>/dovecot-acl) failed: No such file or directory Needless to say the file exists and its contents looks like it should. (Every line is an ACL like "user=testuser ilrws") I took a look at the changelog from 2.0.14 onwards and since it says nothing about my problem I am not looking forward to compiling dovecot myself and installing it. Any ideas why this is happening? Is this a known problem?

[Dovecot] overriding userdb connection host for doveadm-user
by Micah Anderson 10 Dec '11

10 Dec '11

I've got my users in a replicated database setup and dovecot configured with two connect lines in dovecot-sql.conf: connect = host=127.0.0.1 port=3306 dbname=users user=user password=pass connect = host=127.0.0.2 port=3306 dbname=users user=user password=pass this works really well to help balance the load. However, when a new user is created, the replication information sometimes has not made it to the slave database before my user creation process tries to send that new user an email about their new email account. If it hasn't and the email gets sent, then it bounces because postfix thinks the user doesn't exist yet. Replication usually happens within seconds, but could be delayed due to problems. I would like a way to see if the new user's information has been replicated yet before sending the email. I was thinking I could use 'doveadm user' to lookup the user, but I am not sure that I can specify one of the specific 'connect' lines in my configuration to check. Is there a way to override that configuration variable to do this test? I tried various incarnations of passing '-o connect=host='... but doveadm user would just ignore them. thanks for any suggestions! micah ps - yes, I can make my user creation process just 'sleep' for an arbitrary amount of time and by that time the replication should have occured, but that is a bit of a shot in the dark, and doesn't handle longer replication delays that could potentially happen. --

[Dovecot] Make entire mailbox read-only (ACLs?)
by David Jonas 10 Dec '11

10 Dec '11

Hello, Is there a way of locking a mailbox, effectively making it read-only to IMAP clients? I've read through http://wiki2.dovecot.org/ACL. I created dovecot-acl with the content "owner lr" in .INBOX which seems to keep me from copying messages into the folder, but not out. I have the plugin configured correctly, it seems, since MYRIGHTS command shows the correct value: 30 MYRIGHTS "INBOX" * MYRIGHTS "INBOX" lr Am I barking up the wrong tree? Is there an easier way to lock a mailbox? post-login scripting perhaps? Thanks!

[Dovecot] Major bug with hardlinks and lmtp
by Brad Schuetz 10 Dec '11

10 Dec '11

In working on trying to fix the crash issue from my last email I had enabled LMTP delivery to try it out instead of using the LDA. I have discovered that when a single piece of email is to be delivered to multiple users the message is being hard linked instead of copied into each mail box. This is a major problem that makes LMTP unusable in an environment where each mailbox has it's own UID since the hard linked file will only be readable by one of the users. I assume this is related to "maildir_copy_with_hardlinks=yes", however this setting doesn't say anything about hardlinking across different email accounts. -- Brad Schuetz

[Dovecot] Wish list item: %g/%{gid} variable

I think it would be very useful to have a user's GID in a variable. So i could use for example: mail_attachment_dir = /srv/mail/.SiS/%{gid} I use one GID per domain and the aliases fqhns of the domain. When for example example.com would be an alias for exmaple.net (gid: 12345), the attachments would be stored inside /srv/mail/.SiS/12345/, no matter if a message was sent to john.doe(a)example.com or to john.doe(a)example.net. "quota = dict:domain:%{gid}:proxy::quota" would then also work. Regards, Pascal -- The trapper recommends today: c01dcofe.1134217(a)localdomain.org

[Dovecot] "Unstable" vs "Development" vs "Nightly"
by Terry Carmen 09 Dec '11

09 Dec '11

I'm currently running v2.1rc1, but have been seeing errors like: Dec 8 11:31:55 it kernel: auth[18914]: segfault at 48 ip 00fe2f74 sp bfcaccd0 error 4 in libauthdb_imap.so[fdd000+f000] The unstable and nightly builds are newer, but are they likely to be more or less stable than the version I'm currently running? I'd like to install a newer version, but am trying to get a feel for how usable they're likely to be. Thanks, Terry

[Dovecot] Error: Corrupted index cache file /xxx/yyy/zzz/indexes/.INBOX/dovecot.index.cache: invalid record size
by florent＠coppint.com 09 Dec '11

09 Dec '11

Hi all, I got a problem with a Dovecot IMAP/POP installation. Since a recent failure of our distributed file system (no loss of data btw), Dovecot seems to have a problem with index cache files. For a lot of accounts, I have this error in logs: Error: Corrupted index cache file /xxx/yyy/zzz/indexes/.INBOX/dovecot.index.cache: invalid record size If I delete all files from /indexes/ directory, it still occurs... Do you see what can cause this problem ? Or what information can I provide to help ? Our distributed FS is MooseFS. Dovecot is configured like if it was NFS (no mmap, etc...). Thank you for your help :) Flo

Thanks Timo, this patch applied clean against 2.0.16 just running it on live for the past few minutes & seems to have fixed the issues.

[Dovecot] problems when using dsync between servers
by Yann Dupont 08 Dec '11

08 Dec '11

Hello, I'm trying to migrate from maildir++ to mdbox. The maildir++ is a leftover of our previous setup (was using courier) We have 3 virtuals servers for our +70000 accounts. Now, I'd like to use mdbox, so I'm trying using dsync for that. I setup a new virtual server, configured for mdbox. 1st, I tried a basic setup: I established a file with all my accounts (taken from LDAP) and then I use this script : FILENAME=$1 while read LINE do dsync -u $LINE backup $LINE@my_new_server done < $FILENAME But it's quite slow and dsync hangs. So I tried another approach using multi threaded python. Much faster (using all the cores), but dsync still hangs on some accounts. After a certain time dsync exit with an error like that : Panic: file dsync-worker-local.c: line 1688 (local_worker_save_msg_continue): assertion failed: (ret == -1) dsync-remote(E072184L): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x3fd8a) [0x7f34fc577d8a] -> /usr/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x32) [0x7f34fc577e72] -> /usr/lib/dovecot/libdovecot.so.0(i_error+0) [0x7f34fc55119f] -> dsync() [0x40ff0b] -> dsync() [0x410142] -> dsync(dsync_worker_msg_save+0x99) [0x40f639] -> dsync() [0x40e24a] -> dsync() [0x40d8ef] -> dsync() [0x40dbfc] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x48) [0x7f34fc5830d8] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x9f) [0x7f34fc58403f] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7f34fc583068] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f34fc5713a3] -> dsync(main+0x9e1) [0x4078b1] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7f34fbde9c4d] -> dsync() [0x406cf9] This is on a RUNNNING server. My aim was to make some pass on the running server, then stop it and make a last pass to finish the process. Is dsync supposed to run only on a stopped server ? Is my approach totally wrong ? -- Yann Dupont - Service IRTS, DSI Université de Nantes Tel : 02.53.48.49.20 - Mail/Jabber : Yann.Dupont(a)univ-nantes.fr

[Dovecot] sql dict: commit failed: MySQL server has gone away
by Mark Zealey 08 Dec '11

08 Dec '11

Following on from this thread: http://www.dovecot.org/list/dovecot/2010-September/052704.html <https://owa2010.webfusion.com/owa/redir.aspx?C=a447887e3d204944a8c766142df4…> in 2.0.16 I am seeing the same issues. I believe this would be related to some timeouts set on our mysql servers which are pretty low (30 or 60 seconds or so to drop idle connections). This is happening for imap, pop and lmtp processes when they try to update quotas stored in a mysql database; presumably it is the dict process that actually has these issues - the lmtp delivery isn't lasting longer than 1 second so shouldn't be seeing any timeouts there. This is always followed by the "Error: dict quota: Quota update failed, it's now desynced" line; presumably it is telling the truth but I'm not sure how I could tell. We are also seeing this "MySQL server has gone away" issue in login processes but it isn't causing an issue there as presumably dovecot transparently retries rather than just giving up as it seems to in the quota updates. Any thoughts or advice would be appreciated. Mark

Hi, I'm building a Postfix/Dovecot mail server and while I am able to send/receive emails using telnet, after establishing a connection to Dovecot via a client (Mail Live, Thunderbird etc) the following appears in the logs: Nov 28 14:11:02 mailserver dovecot: [ID 583609 mail.info] pop3-login: Login: user=<user(a)domain.com>, method=PLAIN, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx, mpid=282 78 Nov 28 14:11:02 mailserver dovecot: [ID 583609 mail.error] master: Error: service(pop3-login): child 28277 killed with signal 10 (core not dumped - set service pop3-log in { drop_priv_before_exec=yes }) Nov 28 14:11:02 mailserver dovecot: [ID 583609 mail.info] pop3(user(a)domain.com): Disconnected: Logged out top=0/0, retr=0/0, del=0/5, size=3250 I also experience very poor connectivity to the server, with Microsoft Mail and Thunderbird regularly failing to connect (connection errors in the client and no login attempt in the dovecot logs).

Is it possible to specify more than one backend-server IPs as I can do for the database hosts for userdb queries?

[Dovecot] lazy_expunge plugin and folder subscription trouble

[Dovecot] doveadm fetch vs search+fetch
by Joseph Tam 08 Dec '11

08 Dec '11

What's the pactical difference between using "doveadm fetch" rather than using "doveadm search" in conjunction with "doveadm fetch", as the man pages suggest? It seems "doveadm fetch" functionally supercedes "doveadm search" making the latter obsolete. It can even be closely simulated with "doveadm -f tab fetch ... 'mailbox-guid uid' search-query ...".

[Dovecot] IMAP SPECIAL-USE extension
by Timo Sirainen 07 Dec '11

07 Dec '11

It's implemented now in dovecot-2.1 hg. It also deprecates autocreate plugin (but it still works the old way). The idea is that you can now do e.g.: mailbox Trash { auto = no special_use = \Trash } mailbox Drafts { auto = no special_use = \Drafts } mailbox Sent { auto = subscribe # autocreate, autosubscribe special_use = \Sent } mailbox Spam { auto = create # autocreate, but don't autosubscribe special_use = \Junk } mailbox virtual/All { # if you have a virtual "All messages" mailbox auto = no special_use = \All } The mailbox names require a namespace prefix, so if you use e.g. "INBOX." prefix you'll need to use: mailbox INBOX.Trash { ..etc..

[Dovecot] MS Exchange IMAP Proxy
by Terry Carmen 06 Dec '11

06 Dec '11

I need to make the IMAP interface of an Exchange 2000 server available on the net, however I would like to give it a little protection, and believe Dovecot's IMAP proxy might be appropriate. Does anybody have a *really simple* config that would allow IMAP pass-through to a single Exchange server? The examples I've seen all assume some sort of load balancing, which isn't an issue here, so I'd like to eliminate the need for an unnecessary database server. Does Dovecot do any cleanup of the IMAP commands that would be useful in protecting Exchange (from this, http://www.cvedetails.com/cve/CVE-2007-0221/ for example), or am I barking up the wrong tree? If Dovecot isn't helpful for this, can anybody point me to a better resource? Thanks! Terry

My problem is that some users gets the quota enforced, while others don't, and "doveadm user" doesn't seem to agree with "doveadm quota ge gett" Ref: $ doveadm user janfrode(a)example.net userdb: janfrode(a)example.net home : /usr/local/atmail/users/j/a/janfrode(a)example.net mailQuota : quota_rule=*:storage=2100000 $ doveadm -f tab quota get -u janfrode(a)example.net Quota name Type Value Limit % UserQuota STORAGE 760 1000000 0 UserQuota MESSAGE 62 - 0 Why limit 1000000 instead of 2100000 ? $ doveadm user omar(a)example.net userdb: omar(a)example.net home : /usr/local/atmail/users/o/m/omar(a)example.net mailQuota : quota_rule=*:storage=1000000 $ sudo doveadm -f tab quota get -u omar(a)example.net Quota name Type Value Limit % UserQuota STORAGE 0 - 0 UserQuota MESSAGE 0 - 0 $ doveadm user testkunde(a)example.net userdb: testkunde(a)example.net home : /usr/local/atmail/users/t/e/testkunde(a)example.net mailQuota : quota_rule=*:storage=1000000 $ doveadm -f tab quota get -u testkunde(a)example.net Quota name Type Value Limit % UserQuota STORAGE 33918 - 0 UserQuota MESSAGE 137 - 0 Why no storage limit ?

[Dovecot] Dovecot crash non stop: "uid 0: exited on signal 11"

Hi all, I have an old physical freebsd 6.2 server running Dovecot 1.0.7. I wanted to virtualised it. So, I did a dd from the physical server and then I restored it on then now Virtual Machine. I booted the server, all services are running just fine excepted Dovecot. I tried to investigate the log as much as I can but i'm not getting any usefull pieces of information. The only entries I have in the log files are the following: /*log: /var/log/messages:*/ /Dec 5 09:53:35 hostname kernel: pid 33815 (imap), uid 0: exited on signal 11 Dec 5 09:53:39 hostname kernel: pid 33820 (imap), uid 0: exited on signal 11 Dec 5 09:54:22 hostname kernel: pid 33910 (pop3), uid 0: exited on signal 11 Dec 5 09:55:22 hostname kernel: pid 34071 (pop3), uid 0: exited on signal 11 Dec 5 09:55:47 hostname kernel: pid 34103 (imap), uid 0: exited on signal 11 Dec 5 09:56:13 hostname kernel: pid 34143 (pop3), uid 0: exited on signal 11 Dec 5 09:56:21 hostname kernel: pid 34164 (pop3), uid 0: exited on signal 11 Dec 5 09:56:26 hostname kernel: pid 34180 (imap), uid 0: exited on signal 11 Dec 5 09:56:40 hostname kernel: pid 34201 (imap), uid 0: exited on signal 11 Dec 5 09:56:49 hostname kernel: pid 34227 (imap), uid 0: exited on signal 11/ /*log: /mail/log/dovecot.log:* dovecot: Dec 05 10:13:46 Info: imap-login: Login: user=<test-amaury(a)mydomain.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured dovecot: Dec 05 10:13:46 Error: child 36621 (imap) killed with signal 11/ I'm also running a squirrelmail as a webmail and here when I refresh a folder content 3/5 times I'm getting an error: /Error: Connection dropped by IMAP server Query: SELECT "INBOX.Corbeille"/ I'm using Dovecot version 1.0.7 on a freebsd 6.2 and my dovecot.conf is: dovecot -n /# 1.0.7: /usr/local/etc/dovecot.conf base_dir: /mail/ log_path: /mail/log/dovecot.log protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /mail//login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting: POP3/IMAP ready. verbose_proctitle: yes first_valid_gid: 0 mail_extra_groups: mail mail_location: maildir:~/Maildir fsync_disable: yes maildir_copy_with_hardlinks: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota trash mail_plugins(imap): quota imap_quota trash mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: default_realm: tropik.nc passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf socket: type: listen master: path: /mail/auth-master mode: 384 user: vmail group: vmail plugin: quota: maildir trash: /usr/local/etc/dovecot-trash.conf/ Thank you for your help!

[Dovecot] Questions about single intance storage
by Maria Arrea 03 Dec '11

03 Dec '11

Hello We are using dovecot 2.0.16 with mdbox+zlib. We are now testing SiS (Single Instance Storage) and I have 5 questions: 1º Is possible to "dedup" existing mdboxes? 2º Are attachments compressed with zlib if mdboxes already use zlib? 3º I have plenty CPU to spare, should I use a low value of mail_attachment_min_size , like 16KB ? 4º Can I "undo" SiS if I have problems? 5º We use bacula to save indexes & mdboxes, and we recover mailboxes using doveadm import when a user "makes a fatal mistake" wiping all her Inbox. If we enable SiS I am not really sure how can we safely restore a user's INBOX if that user has SiS attachments. Thank you for your (great) support. Maria

[Dovecot] lda/sieve ignores quota from ldap
by Jens Meißner 03 Dec '11

03 Dec '11

Hello, I'm using Dovecot 2.0 with Sieve as MDA and Postfix as MTA. The Postfix delivery command is /usr/lib/dovecot/dovecot-lda -f "$SENDER" -a "$RECIPIENT". I have set a default quota with quota_rule = *:storage=1G. Some users should have a larger quota. This is defined in a ldap directory and I have set user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mailQuota=quota_rule=*:storage=%$. The imap_quota plugin shows the right quota for all users but the lda ignores the quota rule from ldap. If a user is over default quota but not over his ldap defined quota I get the following error message: From: Mail Delivery Subsystem <postmaster@[…]> Your message to <[…]> was automatically rejected: Quota exceeded (mailbox for user is full) The log file shows the following: Nov 30 18:21:17 […] dovecot: lda([…]): Error: sieve: msgid=<20111130172116.7F065A07D@[…]>: failed to store into mailbox 'INBOX': Quota exceeded (mailbox for user is full) Nov 30 18:21:17 […] dovecot: lda([…]): Error: sieve: script /var/mail/[…]/dovecot.sieve failed with unsuccessful implicit keep (user logfile /var/mail/[…]/dovecot.sieve.log may reveal additional details) Nov 30 18:21:17 […] dovecot: lda([…]): msgid=<20111130172116.7F065A07D@[…]>: rejected: Quota exceeded (mailbox for user is full) dovecot.sieve.log: error: msgid=<20111130172116.7F065A07D@[…]>: failed to store into mailbox 'INBOX': Quota exceeded (mailbox for user is full).

[Dovecot] Authentication listener configuration
by Rainer Frey 02 Dec '11

02 Dec '11

Hi, I'm wondering about the authentication listeners that dovecot uses. In many configurations I see: service auth { unix_listener auth-userdb { Does any component of dovecot use this listener internally (lmtp, lda ...) and does that read the config and search for the listener, or is the exact name "auth-userdb" expected? Is this maybe dependent on the userdb? Which ones need it? And if I want to use postfix SMTP auth, should I define a second listener, or just re-configure that default one to postfix's needs? Also, in which cases do I need to define an auth-worker service, and a unix_listener for it? I don't find this in the documentation, if that's caused by my lacking search skills, please just send apointer. Thanks Rainer

[Dovecot] LDAP Authentication - Home Directory Creation
by Stephen Bowman 02 Dec '11

02 Dec '11

How does everyone handle this case? Users are authenticated by LDAP, and do not have accounts on the IMAP/dovecot server. When a new user is added to LDAP, the home directory (/home/newuser) needs to be created on the IMAP/dovecot server so dovecot can create the mail directories inside it (/home/newuser/mail/). Obviously I can come up with a few custom solutions, utilizing cron, but I feel like there's a cleaner solution out there. Thanks!

[Dovecot] dovecot-lda quota rule
by Micah Anderson 01 Dec '11

01 Dec '11

I really like the feature where you can define quota rules with percents which trigger off of the default values[0] (so you can set the Trash to allow for 10% more of the user's quota for example). What I would really love in dovecot would be for the ability to configure a quota rule for dovecot-lda. I would like to configure things so we don't bounce emails for users until they are well over quota, the IMAP quota plugin is a really great way to notify people that they are over quota because it fails to write to other folders.... that should be enough to get people's attention that they need to deal with things, but bouncing is harsh. Is there a way to do this now that I haven't seen? thanks! micah 0. http://wiki2.dovecot.org/Quota/Configuration --

[Dovecot] second active directory
by Айдар Камалов 30 Nov '11

30 Nov '11

Hello! There is dovecot authenticating through AD. All is working well, if authentication is just one of AD. But there is another AD, and working with 2 AD's dovecot don't recognizes last AD user's home directory. For example, if user name in the second AD - 1developer and Mail - it-2c(a)zakamye.ru then dovecot creates folder /var/mail/zakamye.ru/1cdeveloper but it should be /var/mail/zakamye.ru/it-2c. What I do wrong?( And, if I change the order of viewing AD, does not work precisely the second AD: passdb ldap-DUSLYK { driver = ldap args = /etc/dovecot/dovecot-DUSLYK.conf } userdb ldap-DUSLYK { driver = ldap args = /etc/dovecot/dovecot-DUSLYK-users.conf } passdb ldap-DUSL-OFFICE { driver = ldap args = /etc/dovecot/dovecot-DUSL-OFFICE.conf } userdb ldap-DUSL-BASE { driver = ldap args = /etc/dovecot/dovecot-DUSL-OFFICE-users.conf } Sorry for my bad english, but maybe you can understand logs and configs: http://pastebin.com/mtk4XsNE -- Айдар А.

[Dovecot] Fault tolerant architecture
by Marcelo Salhab Brogliato 30 Nov '11

30 Nov '11

Hi, I'm new to this list and want your help. I'm the mail admin for some domains in Rio de Janeiro - Brazil. Today we have only one machine running dovecot (imap+pop3) with local mail. We are migrating to two virtual machines in kvm running in separate hosts. Then we have two main problems: - How to share mail files to both dovecots? We've been thinking about NFS using local indexes. Is this a good approach? - How do we have a fault tolerant mail servers? Our first solutions is using two IP addresses in our DNS records. About NFS using local indexes, I'm configuring a test server. But how to configure local indexes when my mail_location comes from sql (userdb_home actually). I'm using dovecot 1.2.9. I guess you already had some of these problems or maybe in another architecture these neither exists. Thanks for any help, Marcelo

[Dovecot] Best setup for performance and fault tolerance
by Donny Brooks 30 Nov '11

30 Nov '11

Hello all. I am in need of some guidance. First a little background. Currently our mail server is on physical hardware (Dell server with 2x 2.8GHz Xeon w/ 4GB ram, raid5 array, single gigabit nic) running on Fedora 11 and postfix-2.5.6-3.fc11.x86_64 with dovecot-1.2.11-3.fc11.x86_64. Mailstore is via Maildir format that was converted from mbox about a year ago. This same machine is also our PDC with samba, Master LDAP, slave MySQL replication, primary DNS, and home server for about 20 users. We have approximately 200 end users that have mailboxes on the server ranging from 1KB to 20GB in size. Total mail store is currently at 300GB. About 75 of the users are currently POP access and their mail will be moved to the server soon and setup as IMAP. This is calculated to add roughly another 150GB of mail for a total of 450GB mail store. Being a state agency we have to keep the mail indefinitely for public record reasons. We use a mixture of Thunderbird as an IMAP client and SOGo for web access. Now to the problem: Recently we have been having super slow access to the mail server. Turns out the load was insanely high partially due to the samba home server portion, which is being moved off as we speak, and the other part is due to people searching their mail. Just yesterday one of our users nearly brought the entire agency to its knees by performing a search on her 8GB of mail via IMAP. Since the server is old in both hardware and software I have been tasked with moving it to newer hardware and a newer OS. We currently have 3 virtual servers running Xen and a SAN. The new setup will be placed in the virtual environment. I will probably run Fedora 16 as the OS but am open to Centos, Fedora, or Ubuntu. Now to the question: What is the best way to setup Dovecot so that it is tuned for performance and high available? We have been running with this single point of failure for years so as long as we are moving the mail server we might as well build in some redundancy. To solve the searching problem I thought of maybe setting up some type of indexing. I do kind of want to break the various services out on to separate virtual machines for a little more fault tolerance, but that is not totally necessary. What do you think of things like iRedmail? I see it's usefulness but the not being able to separate services kind of defeats the purpose, plus I want to setup a high available MySQL cluster and possibly OpenLDAP or 389 cluster so iRedMail may not be the best solution. Sorry for the long email but I am trying to get all the information out there at once so it will help get more directed responses in the shortest amount of time. I look forward to any and all input on this matter -- Donny B MDAH

[Dovecot] squat fts not working on 2.1rc1
by Metro Domain Admin 28 Nov '11

28 Nov '11

Hello, I tried to upgrade from 2.0.15 to 2.1.rc1 over the weekend but ran into some problems with squat. My two largest mailboxes were corrupted, producing this error: Nov 27 17:38:12 kerio1 dovecot[42860]: imap(bigmailbox): Error: Corrupted squat uidlist file /var/mail/metro-email.com/bigmailbox/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index.search.uids: wrong indexid There is a good chance that I had shot my own foot, by forgetting to update postfix's dovecot-lda reference to the new instance. I had also enabled an inet based LMTP listener, although it is not being used yet. Even using non-corrupted indexes, it seemed that FTS was not being used. A basic search such as this one took many minutes to complete: doveadm search -u jsample mailbox INBOX body eps I found messages like this in mail.log after performing the search: Nov 27 18:21:39 kerio1 dovecot[42860]: indexer-worker(jsample): Indexed 0 messages in Drafts Nov 27 18:21:39 kerio1 dovecot[42860]: indexer-worker(jsample): Indexed 0 messages in INBOX When I rolled back to 2.0.15, the same search returned almost immediately. The larger mailboxes went quickly again, but only after they had a chance to rebuild. A few other notes about our configuration: We are on PPC, with the stats service disabled (because of kqueue issue discussed earlier). I made some minor changes in my config since the previous installed version (diff below). mail_location override is in place for all users via password file, e.g.: userdb_mail=mdbox:/var/mail/metro-email.com/jsample/mdbox Thanks, Tony kerio1:~ metroadmin$ /opt/dovecot-2.1.rc1/bin/doveconf -n -c /opt/dovecot-2.1.rc1/etc/dovecot/dovecot.conf # 2.1.rc1: /opt/dovecot-2.1.rc1/etc/dovecot/dovecot.conf # OS: Darwin 9.8.0 Power Macintosh auth_cache_negative_ttl = 0 auth_cache_size = 1 M auth_mechanisms = plain login lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes lmtp_proxy = yes mail_location = maildir:%h mail_plugins = fts fts_squat mail_log notify mail_privileged_group = mail maildir_very_dirty_syncs = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave editheader mdbox_rotate_size = 10 M namespace { inbox = yes location = prefix = separator = / } passdb { args = scheme=CRYPT username_format=%u /opt/dovecot-2.1.rc1/etc/dovecot/users driver = passwd-file } plugin { fts = squat mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size from subject sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster(a)metro-email.com protocols = imap lmtp service auth { unix_listener /var/spool/postfix/private/auth { group = _postfix mode = 0660 user = _postfix } unix_listener auth-userdb { group = mail mode = 0660 user = metroadmin } } service imap { executable = imap postlogin } service lmtp { inet_listener lmtp { address = 192.168.20.10 127.0.0.1 port = 24 } } service postlogin { executable = script-login rawlog -t } service stats { fifo_listener stats-mail { mode = 00 } } ssl_cert = </opt/local/apache2/conf/ssl_startcom/server.crt ssl_key = </opt/local/apache2/conf/ssl_startcom/server.key userdb { args = username_format=%u /opt/dovecot-2.1.rc1/etc/dovecot/users driver = passwd-file } verbose_proctitle = yes protocol imap { mail_max_userip_connections = 16 } Here is a diff between the current/working and attempted configs: kerio1:~ metroadmin$ diff k1.curr k1.new2 1c1 < # 2.0.15: /opt/dovecot-2.0.15/etc/dovecot/dovecot.conf --- > # 2.1.rc1: /opt/dovecot-2.1.rc1/etc/dovecot/dovecot.conf 9a10 > lmtp_proxy = yes 15c16 < managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave --- > managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave editheader 24c25 < args = scheme=CRYPT username_format=%u /opt/dovecot-2.0.15/etc/dovecot/users --- > args = scheme=CRYPT username_format=%u /opt/dovecot-2.1.rc1/etc/dovecot/users 50a52,57 > service lmtp { > inet_listener lmtp { > address = 192.168.20.10 127.0.0.1 > port = 24 > } > } 53a61,65 > service stats { > fifo_listener stats-mail { > mode = 00 > } > } 57c69 < args = username_format=%u /opt/dovecot-2.0.15/etc/dovecot/users --- > args = username_format=%u /opt/dovecot-2.1.rc1/etc/dovecot/users kerio1:~ metroadmin$

[Dovecot] Which FTS to use!
by Henrique Santos Fernandes 27 Nov '11

27 Nov '11

Hello, i am currently using squat dovecot, but some users that have lots os emails ( 1GB ) are complaining about speed. Iam using dovecot 2.0.13 on debian 6 my squat conf is plugin { fts = squat fts_squat = partial=4 full=5 } I am thinking in maybe start to use Solr, so any one can help me with an decision? I am probably gonna update dovecot to 2.1 next year. and them maybe change the FTS plugin. This year i will get 10k disk only to store the dovecot index, rigth now they are saved on the same storage that the mails are and also change the "full" parameter to something like 10 or 15 I know i will use more disk space for it, but it will make a lot of differences right? it will match the message without the need of opening it for any search smaller than 10 character i guess. But this will be enough? or Solr or Lucene still better? Anyway, i am not current updating the indexes automatic, but i am planing on it, just not sure what is better, the command doveadm index or doveadm search... with one is better to do the task? Thanks! []'sf.rique

[Dovecot] Seen flag getting lost
by Edgar Fuß 26 Nov '11

26 Nov '11

We have two dovecot 1.2 instances sharing Maildirs on NFS. Indexes are local to the individual servers. Occasionally (no idea how to trigger this), the Seen flag gets lost on some messages. I've verified that actually the ``S'' is missing from the filename. I suspect something like server A caching the flags, server B setting Seen, and then server A flushing its cache for another change so overwriting what B changed. Any ideas short of switching to 2.0?

[Dovecot] v2.1.rc1 released
by Timo Sirainen 25 Nov '11

25 Nov '11

http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc1.tar.gz http://dovecot.org/releases/2.1/rc/dovecot-2.1.rc1.tar.gz.sig I'll probably release v2.1.0 pretty soon, unless people report some new bugs. I know v2.1 is already being used to serve mails to tens (or hundreds?) of thousands of users, so it should be pretty stable. Most of the changes since v2.1.beta1 have been for rather small issues. Many of the fixed bugs exist also in v2.0, but since they are so minor I didn't bother backporting the fixes. As new features since v2.1.beta1 there are the things I did also for v2.0.16, and: * ssl_client_cert/key: Proxying can now send SSL certificate to backend server * ssl_crypto_device for enabling hardware encryption * SCRAM-SHA-1 authentication mechanism support by Florian Zeitz * passdb/userdb checkpassword: Export all auth %variables to AUTH_* environment. * maildir_broken_filename_sizes setting for people upgrading from other maildir servers that wrote tons of broken S=<size> values And as a reminder, here are the biggest new things since v2.0: * Plugins now use UTF-8 mailbox names rather than mUTF-7: acl, autocreate, expire, trash, virtual * auth_username_format default changed to %Lu. If you really want case sensitive usernames, set it back to empty. * Solr full text search backend changed to use mailbox GUIDs instead of mailbox names, requiring reindexing everything. solr_old backend can be used with old indexes to avoid reindexing, but it doesn't support some newer features. + imapc (= IMAP client) storage allows using a remote IMAP server to be used as storage. This allows using Dovecot as a smart (caching) proxy or using dsync to do migration from remote IMAP server. + Mailbox indexing via queuing indexer service (required for Lucene) + Lucene full text search (FTS) backend rewritten with support for different languages + FTS finally supports "OR" search operation + FTS supports indexing attachments via external programs + IMAP FUZZY extension, supported by Lucene and Solr FTS backends + Mailbox list indexes + Statistics tracking via stats service. Exported via doveadm stats. + Autocreate plugin creates/subscribes mailboxes physically only when the mailbox is opened for the first time. Mailbox listing shows the autocreated mailboxes even if they don't physically exist. + Password and user databases now support default_fields and override_fields settings to specify template defaults/overrides. - listescape plugin works perfectly now

[Dovecot] How to create home directories for virtual users?
by Olli Räisänen 25 Nov '11

25 Nov '11

Hello, I,m using Dovecot 1.2.9, now finishing a migration from Courier IMAP. Documentation (http://wiki.dovecot.org/VirtualUsers/Home) says that home directory should not be the same as mail directory. When I create new user accounts with PostfixAdmin the mail directory is not a problem but is there some smart way to create the home directory as well (locating it for instance in '/srv/vmail/%d/%n/home')? Regards, Olli

[Dovecot] Problem with lmtp proxy
by Miguel Tormo 24 Nov '11

24 Nov '11

Hello everyone, I have set up postfix to deliver mails to dovecot (2.0.16) using LMTP. On the other hand, I've successfully configured the IMAP proxy setting in dovecot in order to be able to distribute mailboxes among different servers. I wanted to do the same proxy at LMTP level, but it's not working. If I put lmtp_proxy = no, then everything works ok (assuming the mailbox is local), but when I set lmtp_proxy = yes then the user is not found when deliverying the message via LMTP, so the mail remains in the postfix queue. Users are validated through active directory. However, this AD hasn't the SFU installed, thus its LDAP schema doesn't provide me with the required uid, gid, etc. To solve this, I have winbind configured in the system, so I'm doing this: - To validate users *and* be able to set the proxy extra fields, I use ldap as "passdb" (I believe it's not possible to use proxies with PAM). I'm using some LDAP field to store the host that has the user's mailbox. - In order to get the user account data that is not available in the AD, I use passwd as "userdb". I know that when using LMTP with proxy, a passdb needs to be configured. I assume this is needed for the service to lookup for the appropriate host to send the message. So, initially I set ldap as the passdb for LMTP, but just because it didn't work I put both ldap and passwd, and even a userdb (passwd), but the problems remain the same. Anyway the ldap should be the right one as it is there where I have the host information for each user. I think I'm missing something but I can't find what it is.

[Dovecot] modules directory
by Johannes Berg 24 Nov '11

24 Nov '11

Hi! I'm a little confused with how plugin loading works in dovecot 2, I can't seem to make it load from $(moduledir)/imap/. Is that intended to work? Just a configuration issue? Reason I ask is that I ported my antispam plugin (I know there's a fork, but I still like mine better) to dovecot 2 and the default "make install" no longer loads properly with just "mail_plugins = antispam". So is $(moduledir)/imap/ no longer used? I also notice acl/imap_acl now, but I still see subdirectories for at least auth. Should I install into just $(moduledir)/ now? johannes

Re: [Dovecot] Solaris hardware crypto engines
by Martin Preen 24 Nov '11

24 Nov '11

Hello, after serveral tests (and reading a lot of howto's) I'm now fairly convinced that the Solaris HW-crypto engine is not automatically used. Even when dovecot ist compiled with the OpenSSL version provided by Solaris. Currently I have only a T1-CPU available for testing (Sun Fire T2000) and after patching src/login-common/ssl-proxy-openssl.c (Dovecot 1.2.17) with ENGINE *e; ENGINE_load_builtin_engines(); ENGINE_init((e=ENGINE_by_id("pkcs11"))); ENGINE_set_default_RSA(e); ENGINE_set_default_DSA(e); ENGINE_set_default_ciphers(e); in ssl_proxy_init() and inserting ENGINE_cleanup(); in ssl_proxy_deinit() the crypto device gets used. I'm sure that this is not the whole story since this only seems to affect the IMAP login. One has to use the specific SSL-engine and the ENGINE/EVP calls (as stated in the various articles). Is there any chance that Dovecot gets updated/patched for this ? E.g. Like the SSLCryptoDevice setting in Apache's mod_ssl. Regards.

[Dovecot] seting acl for master user?
by oni-neko＠gmx.net 24 Nov '11

24 Nov '11

Hello! I'm sorry, but i don't really understand it the way it is written in the wiki, so i'm trying my luck here =) i followed the wiki for creating a master user (the non-sql-version) and i can login as another user via this master user. my dovecot version is 1.2.9 on an ubuntu server 10.4.3 lts. what i don't get is the acl-setting, so that the master-user can access all the other users mails and folders. i made the changes in the dovecot.conf as written in the wiki: protocol imap { mail_plugins = acl imap_acl } protocol lda { mail_plugins = sieve acl } plugin { acl = vfile:/etc/dovecot/acls } in my case I only want the master user (called cyrus) to be able to do everything with/in all mailboxes, so I made a file /etc/dovecot/acls/default that reads "user=cyrus lrwstipekxa". i'm pretty sure i'm missing something rather obvious here, but somehow i'm just stuck. any help would be greatly appreciated. thanks in advance =) silvana -- NEU: FreePhone - 0ct/min Handyspartarif mit Geld-zurück-Garantie!

[Dovecot] Random Loss of Connection with Thunderbird and Dovecot
by Jay Welch 24 Nov '11

24 Nov '11

Hi, Dovecot Version: 1.2.16 OS: CENTOS 5.5 I am having issues with Thunderbird connecting to Dovecot at random times. Usually an error comes up and states that Thunderbird cannot connect to the server. The only way I have been able to fix this is reset/repair the network connection or reboot the computer. Is there any parameters I can change in Dovecot to fix this issue? Does anyone know what is likely going on? I have been reading forums and I cannot find anything. Thanks

[Dovecot] Excluding some system users after configuration
by Nanitous 24 Nov '11

24 Nov '11

Dear readers, Consider an installed Postfix configuration (2.3.3) on CentOS. Now I want to install Dovecot (alas only version 1.0.7.7 is available) to provide IMAP services for a few system users, but not all. Most importantly the mail delivery by postfix for some of these system user /must/ not change after the installation of Dovecot. How can I prevent the installation of Dovecot to touch some specific system user accounts? Thanks in advance, /Twan

[Dovecot] How to disable pop3 in version 2?
by Knute Johnson 24 Nov '11

24 Nov '11

I'm about to bring up a new mail server running Ubuntu 11.10 with Dovecot 2. I've been using 1.2 all along and there are a bunch more config files in 2. In 1.2 I just edited the protocols statement but I can't find one in version 2. Is there a way to disable pop3 or do I just firewall the ports? And a related question, I've been using imaps on port 993 but I hear that's not the best solution anymore, I should be using imap with STARTTLS? How do I disable imaps? Thanks, -- Knute Johnson

Sorry about the HTML. I removed the string "-O2" from the /auth Makefile and, for good measure, did make clean, make and make install for all of Dovecot.

[Dovecot] 1.2.15 can't get zlib working
by Stan Hoeppner 24 Nov '11

24 Nov '11

Following these instructions: http://wiki.dovecot.org/Plugins/Zlib I enabled zlib and restarted Dovecot. I made a backup copy of a 68MB mbox file and moved it to a non mail directory. The mbox file is an existing TBird IMAP folder in my UNIX user mail directory. It is an archive of a defunct mailing list. It was a regular IMAP folder prior to attempting this. I was able to access all emails in the folder. It worked fine. I gzipped the original mbox file down to 14MB and removed the write flag with chmod. I launched TBird and received the following error in Activity Manager when accessing this IMAP folder: The current operation on '1-Spam-l' did not succeed. The mail server for account stan(a)hardwarefreak.com responded: Mailbox doesn't exist: 1-Spam-l I deleted the Dovecot index files and the TBird 1-Spam-l.msf file which didn't help. Curiously, there are no entries in either dovecot.err or dovecot.log, giving not even the slightest hint as to where I should troubleshoot. Kinda sucks when one follows instructions exactly, simple instructions at that, and it doesn't work, and generates zero log errors. A bit frustrating...

[Dovecot] v2.1.beta1 released
by Timo Sirainen 23 Nov '11

23 Nov '11

http://dovecot.org/releases/2.1/beta/dovecot-2.1.beta1.tar.gz http://dovecot.org/releases/2.1/beta/dovecot-2.1.beta1.tar.gz.sig Here's the first beta release of Dovecot v2.1. This version has already been tested quite a lot, so I'm not expecting any major bugs. So please upgrade and see if you can find any problems. I'm optimistic about getting rc1 released this year and perhaps even v2.1.0. Since alpha2 there have been a lot of fixes, especially to imapc backend. There are probably also some small new features, but nothing huge. As a reminder, here's the largest changes since v2.0: * Plugins now use UTF-8 mailbox names rather than mUTF-7: acl, autocreate, expire, trash, virtual * auth_username_format default changed to %Lu. If you really want case sensitive usernames, set it back to empty. * Solr full text search backend changed to use mailbox GUIDs instead of mailbox names, requiring reindexing everything. solr_old backend can be used with old indexes to avoid reindexing, but it doesn't support some newer features. + imapc (= IMAP client) storage allows using a remote IMAP server to be used as storage. This allows using Dovecot as a smart (caching) proxy or using dsync to do migration from remote IMAP server. + Mailbox indexing via queuing indexer service (required for Lucene) + Lucene full text search (FTS) backend rewritten with support for different languages + FTS finally supports "OR" search operation + FTS supports indexing attachments via external programs + IMAP FUZZY extension, supported by Lucene and Solr FTS backends + Mailbox list indexes + Statistics tracking via stats service. Exported via doveadm stats. + Autocreate plugin creates/subscribes mailboxes physically only when the mailbox is opened for the first time. Mailbox listing shows the autocreated mailboxes even if they don't physically exist. + Password and user databases now support default_fields and override_fields settings to specify template defaults/overrides. - listescape plugin works perfectly now

[Dovecot] dovecot as an imap "client"
by David LEROUX 23 Nov '11

23 Nov '11

Hi, I need to get emails from one of my users imap account on a server which is not managed by us to his local imap mailbox. I'm almost sure that I've read some times that dovecot would be able to do that, kind of imap relay, but I can't find it again. I'm not sure to be very clear. Thanks, -- David

[Dovecot] [PATCH] SCRAM-SHA-1 authentication
by Florian Zeitz 23 Nov '11

23 Nov '11

Hy, over the last days I have implemented SCRAM-SHA-1 in Dovecot's 2.1 branch. It does not do SCRAM-SHA-1-PLUS, but should be extendable enough to introduce it later. There are some checks for the message format which (assuming the client acts correclty) are not strictly necessary during parsing. This is partially in the hope that it might aid client implementers, partially because it (IMHO) improves readability when checking against the RFC. Also errors found in this way could be sent to the client, this is however strictly OPTIONAL in the RFC, for now they are just logged. Some of the variable names are rather long. This is in order to have them match the terms introduced in the RFC, again I expect it to help readability (maybe my recent Objective-C programming showing though). I do feel somewhat insecure about my usage of some lib functions. Hopefully no API has been abused too much. I also note that there are a lot of fields in the scram_auth_request struct. I think they are all there for a reason, however feel free to prove me wrong. Attached is a hg export. It also includes a hmac-sha1 implementation, an adaption off of the hmac-md5 implementation already in Dovecot. I guess those should eventually be merged into a hash-independent hmac implementation, but I figured this would have to do for now. The implementation has been tested against GNU SASL and does appear to work fine. (The command line was `gsasl -m SCRAM-SHA-1 -a user -p pass --imap host` for those curious) Regards Florian "Florob" Zeitz

[Dovecot] Can't delete sub-folder
by pch0317 23 Nov '11

23 Nov '11

Hi list, I have problem with deleting sub-folder. I use thunderbird 8.0 as a client and dovecot 2.0.9 with imap protocol as a server. I use dovecot with tb-extra-mailbox-sep parameter. I use mbox mailboxes and thunderbird with *not checked* option 'server supports folders that contain sub-folders and messages' so when I create sub-folder I can choose between 'folders only' and 'messages only'. When I try to delete 'parent' folder which contain 'messages only' folder, error message appear: [ALREADYEXISTS] Mailbox has children, delete them first. Ok, so I delete 'message only' folder first and try to delete parent folder, but the same error appear: [ALREADYEXISTS] Mailbox has children, delete them first. When I list mailboxes from console I see inside 'parent' folder ".imap" folder. When I delete .imap folder from console and then delete parent folder from thunderbird, parent folder is deleted correctly. Which application create this ".imap" hidden folder and how solve this problem. Thanks

[Dovecot] Unique message IDs?
by Alexander Chekalin 23 Nov '11

23 Nov '11

Hello, I'm working with indexing my mail box. What I need is to have index in which mailing specified header string is located. I work with the messages via IMAP. I know that sounds like FTS can help me but no, I don't want to index whole message nor I want to patch FTS source to make it to index headers only. I need a way to identify message across my mail box. The idea is that I can move messages between IMAP folders and the index still should be able to identify it. What I want to know, will UID strings be unique across all my messages no matter which IMAP folder it belongs now to, or the UID can change if I move message? If I remove dovecot-uidlist from the folder will UIDs of messages in the folder be changed? What happened if I put a message to the given IMAP folder (and dovecot-uidlist will record UID for it), then shut down dovecot, and (given maildir storage model) move the message's file info another folder in the same mail box - after I start dovecot, will the UID for the message be the same or not? Thank you in advance, Alexander Chekalin

[Dovecot] dsync strange duplicate directories
by Frank 23 Nov '11

23 Nov '11

Hello, i'm testing whether dsync will help me in setting up a redundant master - master imap setup and experience this: 1. Master 1 dovecot is running, master 2 dovecot is down 2. I use rsync to create an exact copy of the master 1 maildir on master 2 3. I start up master 2 dovecot 4. I do a dsync on master 2: dsync -D -u test(a)example.com mirror ssh root@master1 dsync -D -u test(a)example.com Now what i see is this: Each mail directory is duplicated on master 1 and master 2 to a directory name with some MD5 hash value (as it seems) e.g. before dsync: ls -a /home/vmail/example.com/test/Maildir cur new .Drafts .Junk .Sent ... after dsync: ls -a /home/vmail/example.com/test/Maildir cur new .Drafts .Drafts_af61060f6f9fcb4efc0a00002691362e .Junk .Junk_b261060f6f9fcb4efc0a00002691362e .Sent .Sent_b261060f6f9fcb4efc0a00002691362e ... The new directories contain the same files as the original directories. What am i doing wrong? Thanks for the help Frank

[Dovecot] No duplicates on imap copy?
by Alexander Chekalin 22 Nov '11

22 Nov '11

Hello, when from my script I try to copy messages from one imap folder into another own (within the same imap mailbox). That works perfectly, but... If I copy the same message N times from one folder into another one, in the destination folder I see N copies of the same message, each with its own UID. I wonder if there any way to deduplicate folder content (so in the destination folder I'll get only one copy of each message)? I'd implement something like that myself in my script but I just don't know which part of the messages should I compare - probably md5 of headers? Thank you in advance! Yours, Alexander Chekalin

[Dovecot] Dovecot Log analysis

Hello, Before writing them myself, I'd like to figure out if some tools exist (anvil ? ...) and how to use them to extract from dovecot logs things like who is doing what and how hard or how fast in order to do some rate limiting. For instance, I'd like to be able to identify, slow or block users who . read or write to much / slice of time . login/logout too often / slice of time Note : I'm still using the 1.2.x branch.

[Dovecot] Dovecot performance issues with many writes
by Andy Robbins 21 Nov '11

21 Nov '11

We are currently experiencing performance issue with our Dovecot system which we believe is caused by excessive writes to the dovecot files. The confusing thing is that we are seeing more writes than reads on our Dovecot volume when you would assume that most of the IO should be reads from customers checking their mail. We're seeing reads vs. writes similar to the following: # iostat -d 5 -x Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util dm-4 0.00 0.00 485.80 865.80 3886.40 6926.40 8.00 28.69 19.63 0.70 94.00 drbd0 0.00 0.00 485.80 865.80 3886.40 6926.40 8.00 111.42 94.44 0.74 99.60 We can't figure out why we would be seeing twice as many writes as we are reads. Could this have something to do with the index files? Appreciate any assistance on this issue.

[Dovecot] Question about imaps
by jgiles＠cybermesa.com 21 Nov '11

Hi List! Had a questions about imap vs. imaps. I read the ssl article at http://wiki2.dovecot.org/SSL and from what I am reading, imaps is no longer needed as imap with initiate SSL/TLS on its own if STARTTLS is started and I have disable_plaintext_auth=yes and ssl=required settings. I do have SSL up and working, and can connect using imap (143) to my server without issue, but was not able to connect using imaps (993) using Kmail as my client. I Was getting a client error stating that the authentication failed using my password. However, there was nothing in the mail.err or mail.log file even when I enable debugging. If I specify imaps as my only protocol, then dovecot fails to even start without any error loging at all. As I stated, imap works just fine. So, is imaps deprecated as mentioned in the article and imaps no longer needed? I am running Dovecot 2.0.13 on an Ubuntu 11.10 64bit server. This server is simply an imap serer and not a MTA (No postfix or sendmail installed.) Thanks! Joe

[Dovecot] issues with 2.1b1 on OS X
by metro_domain_admin＠fastmail.fm 21 Nov '11

Two issues came up for me when building 2.1beta1 on OS X (10.5.8 on PPC). The first was already mentioned in an earlier thread by a BSD user (http://dovecot.org/list/dovecot/2011-September/061201.html) I just wanted to point out that the error is still occurring in spite of a new test for GNU ld in the configure script. I needed to remove "-no-undefined" specifically: #NOPLUGIN_LDFLAGS="-no-undefined" if test "$with_gnu_ld" = yes; then NOPLUGIN_LDFLAGS="$NOPLUGIN_LDFLAGS -Wl,--as-needed" fi More important, Dovecot aborts on launch with the following error: Nov 19 10:23:52 kerio2 dovecot[33553]: master: Fatal: kevent(EV_ADD, READ, 16) failed: Invalid argument I configured using the same args as I had used successfully on 2.0.15: --with-gssapi --with-ldap --with-sql --prefix=/opt/dovecot-2.X.X. I also tried an exact copy of my known-good config from 2.0.15, to no avail. Thanks, Tony
