[Dovecot] incremental backups of maildir via rsync
by Harald Dunkel 17 Jul '12

17 Jul '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi folks, I would like to do incremental backups of the users' maildir directories to a dedicated backup host (using "rsync -SHa" and rsnapshot). Problem is: Dovecot bloats the incremental backup by changing the file names again and again. Is there some way to tell Dovecot to keep meta information separate from the file names? Any helpful comment would be highly appreciated.

[Dovecot] Last login datetime on accounts
by Robert Blayzor 16 Jul '12

16 Jul '12

I have searching for the best way to tell if a Dovecot user is idle by finding the last time they have logged in. Right now the best way I can tell is to do something like "touch" a file in the users homedir via a post login exec. This seems like a LOT of overhead, to accomplish such a simple task, especially if your doing a lot of dozens of logins per second. Is there an easier/better way? Is there a way to possibly tell Dovecot to refresh the mod time on an index file whenever the user successfully auths or to refresh a separate file in the homedir, ie: ~/.lastlogin (not ~/Maildir/.lastlogin as that would obviously cause some issues) Seems like something that would be far less overhead than calling a shell, execing another command, etc. I'm open to other ideas/alternatives if they are out there!

[Dovecot] Multi Server Exim/Dovecot and NFS
by Robert Blayzor 16 Jul '12

16 Jul '12

In reading the Dovecot NFS WIKI entry: http://wiki2.dovecot.org/NFS It mentions a FreeBSD NFS client caching bug. I believe that bug only exists pre-8.x ? It seems that a patch in the PR notes was MFC'd and made it into 8.x at some point. (at least I checked the source in 8.3 and it was there). So I assume that FreeBSD 8.x mitigates the issue? Maybe not? So our deployment is multi server Dovecot/Exim running on FreeBSD servers, frontended by a layer3 load balancing switch and a NetApp NFSv3 datastore. The only real concern we have right now is race conditions and file write contention on the Dovecot index files. Our original plan was to use Dovecot LMTP on the servers to deliver to the inbox, but that doesn't seem to be recommended as we'll have a number of servers all acting as primary MX for domains and delivering to the same set of mailboxes. So are the Dovecot dotlock file locking mechanisms not enough for multiple servers trying to write/access index files in Maildirs? If we have to deliver straight to the ~/Maildir/new out of Exim, that's fine, also. We're just wondering if there is a added benefit of actually using LMTP. (other than making sure the index are kept the most recent). The other concern we have is client mailbox access. While we can make sessions "sticky" from one IP so they hit the same server, it doesn't help with the person that checks their email via POP from their PC while having their mobile phone access it via IMAP. (obviously from different IP addresses). So I guess there is some possibly index file write contention there as well. (though hopefully this should be rare). I'm curious as to know others experiences with a similar deployment. TIA -- Robert Blayzor INOC, LLC rblayzor(a)inoc.net http://www.inoc.net/~rblayzor/

[Dovecot] ACL with MySQL dict => full table scans
by Roland Rosenfeld 16 Jul '12

16 Jul '12

Hi! I'm just installing ACL support on 2.1.6. When a user changes these ACLs, this results in a full table scan on the dictionary, that tells dovecot who shares with whom. Here's what queries I see when I run $ doveadm acl delete -u user1 shared/user2/folder user=user1 1: SELECT dummy,to_user,from_user FROM imap_acl_shares 2: SELECT dummy,from_user FROM imap_acl_anyone 3: BEGIN 4: DELETE FROM imap_acl_shares WHERE to_user = 'user1' AND from_user = 'user1' 5: INSERT INTO imap_acl_shares (dummy,to_user,from_user) VALUES ('1','user1','user1') ON DUPLICATE KEY UPDATE dummy='1' 6: DELETE FROM imap_acl_shares WHERE to_user = 'user2' AND from_user = 'user1' 7: INSERT INTO imap_acl_shares (dummy,to_user,from_user) VALUES ('1','user2','user1') ON DUPLICATE KEY UPDATE dummy='1' 8: COMMIT Line 2 is okay, since imap_acl_anyone is always empty (I'm not able to disable this query, otherwise dovecot spawns errors about a missing map, but I can live with this). Don't ask me what lines 4/5 are repeated in 6/7, but these use indexes and I can live with this. But what the hell is line 1? Why doesn't dovecot use a WHERE clause here with either to_user='user1', to_user='user2', from_user='user1', or from_user='user2'? All these WHERE clauses would use an index and speedup the query. Without the WHERE clause I expect 100000 or more results on our production system, which could slow down it massively. Here's my setup: /etc/dovecot/dovecot-dict-sql.conf: connect = host=foo dbname=mail user=imap password=hidden map { pattern = shared/shared-boxes/user/$to/$from table = imap_acl_shares value_field = dummy fields { from_user = $from to_user = $to } } map { pattern = shared/shared-boxes/anyone/$from table = imap_acl_anyone value_field = dummy fields { from_user = $from } } And dovecot -n: # 2.1.6: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.5 auth_cache_negative_ttl = 5 mins auth_cache_size = 100 M auth_cache_ttl = 5 mins auth_default_realm = example.com auth_master_user_separator = * auth_mechanisms = plain login auth_verbose = yes dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf } disable_plaintext_auth = no listen = * log_timestamp = "%Y-%m-%d %H:%M:%S " mail_fsync = always mail_gid = 999 mail_location = maildir:~/mail mail_plugins = acl quota mail_uid = 999 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 imapflags mmap_disable = yes namespace { list = children location = maildir:%%h/mail:INDEX=~/mail/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = prefix = separator = / type = private } passdb { args = /etc/dovecot/passwd.master driver = passwd-file master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { acl = vfile acl_shared_dict = proxy::acl quota = maildir sieve = ~/.dovecot.sieve sieve_dir = ~/mail/sieve sieve_extensions = +imapflags } protocols = imap pop3 sieve service auth { unix_listener auth-master { group = vmail mode = 0600 user = vmail } } service dict { unix_listener dict { group = vmail mode = 0600 user = vmail } } service imap { process_limit = 4000 } service managesieve-login { inet_listener sieve { port = 4190 } } service managesieve { process_limit = 100 } service pop3 { process_limit = 1000 } shutdown_clients = no ssl = no syslog_facility = local2 userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } verbose_proctitle = yes protocol imap { mail_max_userip_connections = 10 mail_plugins = quota imap_quota acl imap_acl } protocol pop3 { mail_plugins = quota pop3_no_flag_updates = yes pop3_uidl_format = %v.%u } Tschoeeee Roland

Hi Wojciech Thanks for your comeback.. > maybe - just as in article below > http://www.bishnet.net/tim/blog/tag/maildir-to-mbox/ > you like archive in such format I'm trying to switch dovecot to MBox, not just make archives.

Does anyone else know the correct way to either switch the existing Maildir multiple file format to the single MBox file format. Failing that, though it will mean a LOT of work, how do I get dovecot to work in future in MBox single file format.

For example, pop3 is at 1110 and pop3s at 1995 (on backend side). is it possible? how should I separate this ports in director's config? it's easy for one port: for example lmtp - you just use passdb in protocol lmtp {}

[Dovecot] Issues with Plus addressing and detail part of subaddress.
by Sean Kamath 16 Jul '12

16 Jul '12

Hi all, So, it's been a while. I'm just ramping back up with Dovecot after a hiatus of a few years. I've been using it fine, complete with Sieve, for about a year, with little or no issues. I finally got around to setting up a second account, to start figuring out how I want to do some plus address filtering. In a nutshell, I want to put mail for foo+bar in foo's 'bar' folder. That's in the wiki. I did this: require ["fileinto", "envelope", "subaddress"]; if header :contains "subject" ["test"] { fileinto "Test"; } if envelope :detail "to" "test" { fileinto "test"; stop; } So, this fails miserably. No error message, nothing in the logs, no nothing. Yet, when I run sieve-test .dovecot.sieve /path/to/testmessage it works just fine. I even run sieve-test -e .dovecot.sieve /path/to/testmessage and it files it just fine into the folder. I tried adding some debug logging, but it looks like vnd.dovecot.debug isn't in my version. I searched the archives, and found a bit about adding (explicitly) the delimiter to the plugin section of 90-sieve.conf. So I did that. I'm running 2.0.13 of dovecot, and pigeonhole 0.2.3 on Solaris 10. Before I dive in and upgrade everything, am I missing something simple? The "test" bit works just fine (and in another account as well), so I think something's just not seeing the detail in subaddressing when mail is delivered (even though it works just fine with sieve-test). Thanks, Sean

[Dovecot] Migrating with dsync and INBOX.INBOX namespace issue
by Nikolai Schupbach 15 Jul '12

15 Jul '12

I'm working on migrating IMAP users from Mirapoint Message Servers to Dovecot servers. The Mirapoint IMAP server uses INBOX as a namespace for private mailboxes. I created the same namespace in Dovecot, but when I migrate mailboxes dsync seems to ignore/miss the namespace on Mirapoint and I end up with all mailboxes under a INBOX.INBOX hierarchy. Mirapoint Source Server ----------------------- * OK server.name Mirapoint IMAP4 3.8.3-GA server ready 1 LOGIN test(a)test.com test 1 OK User logged in 2 NAMESPACE * NAMESPACE (("INBOX." "."))

First, this sub discussion in this thread has been dealing strictly with mechanical storage, and that was intentional.

[Dovecot] recover .sieve plaintext from .sievec binary file
by Florin Andrei 10 Jul '12

10 Jul '12

Hi, I upgraded a server from an old Linux distribution to a much newer one. In the process, Dovecot got upgraded from v1 to v2. By mistake, I deleted the .sieve plaintext file with all the Sieve filters, but I still do have the .sievec compiled binary. Is there any way to dump the binary file back into plaintext format? Keep in mind, I'm running v2 now, and the binary was made on a v1 Dovecot server. Thanks. -- Florin Andrei http://florin.myip.org/

[Dovecot] mailboxes missing after upgrade from 2.1.4 to 2.1.7
by Micah Anderson 09 Jul '12

09 Jul '12

Hi all, I mentioned this on the #dovecot irc channel, but I thought I would post here so I can provide more details. The basic problem is that when I upgraded from 2.1.4 to 2.1.7, some users no longer are able to see their folders in pine/alpine. The folders are actually there, and are subscribed (according to doveadm) and its possible to do operations on those folders, if you know the name (for example, opening the folder works fine if you know the name). When I downgrade to 2.1.4 again, the folders appear again, so its clearly something that changed between the two versions. I looked through the changelog, and found a few possibile culprits, I think pine/alpine use imapc, so that could be related: . imapc: Use imapc_list_prefix also for listing subscriptions .

[Dovecot] I changed the separator from . to / and it still seems to work.
by Hans de Groot 06 Jul '12

06 Jul '12

Hello, Just as an experiment I changed the separator from . to / restarted dovecot (v2.1.1). When adding an existing account with lots of mail folders to thunderbird everything still seems to work. My directory layout is like this: .Info.mailinglists .Info.mailinglists.Horde .Info.mailinglists.modperl .Info.mailinglists.PDNS .Info.mailinglists.Sogo .Info.mailinglists.tinc .Info.mailinglists.Zabbix I added a new folder to the horde mailing using thunderbird list and got an extra folder .Info.mailinglists.Horde.testinhorde Does this mean the separator has nothing to do with the . in the directory names and I am safe to switch saparators without having to do anything else?

[Dovecot] Dovecot v2 shared mailboxes , a . separator and complete emailaddress as username.
by Hans de Groot 06 Jul '12

06 Jul '12

Hello, I've been trying to get shared mailboxes to work and got stuck. I tried lots of examples made the shared dict but the shared mail boxes never showed up. I am using the . separator and I think this the problem. I changed it to a / separator and now I could see my shared mailboxes. Checking the maillog in debug mode I saw a few failed login attempts between the succesful logins. The weird thing is that the username was changed, instead of hansg(a)debushalte.nl the login was hansg@debushalte without the .nl part and that user is not in my database. So I suspect that dovecot splits the shared path based hansg(a)debushalte.nl shares mailboxes with dean(a)debushalte.nl below a few lines from the log: Debug: Namespace : type=shared, prefix=INBOX.shared.%u., sep=., inbox=no, hidden=no, list=yes, subscriptions=no location=maildir:%h/mail:INDEX=/mail/debushalte.nl/dean/mail/shared.%u Debug: shared: Tried to access mails of nonexistent user hansg@debushalte Debug: Namespace INBOX.shared.hansg@debushalte.: Creating storage despite: Root mail directory doesn't exist Is there a work arround for this? I really like to keep using '.' as a seperator so I do not have to change all the existing mailboxes. If I do rename and move all existing mailboxes the '/' separator way and of course change the separator in the namespaces would my users notice this? (ie would they have to change something in their mail clients?) Regards Hans

[Dovecot] dovecot and nfs readdir vs readdirplus operations
by Angel L. Mateo 06 Jul '12

06 Jul '12

Hello, We are having performance problems trying to migrate our pop/imap servers to a new version. Our old servers are 4 debian lenny with 5GB of RAM running of XenServer VMs with kernel 2.6.32-4-amd64 and dovecot 1.1.16. New servers are 4 ubuntu 12.04 with dovecot 2.1.5 running on vmware vm with 6 cores and 16GB of RAM and kernel 3.2.0-24-generic. On both server we are using nfs 3 with same configuration (regardless of internal kernel differences, but we have no customized any of them, we are using vanilla kernels with default configurations). The problem we have is that new servers have performance problems. Even when have a small part of our total users (about 25%) directed to the new farm, performance is very poor, even useless. Looking for NFS problems, we have found a lot of differences in nfs operations. For example, this is the nfsstat of one of a new servers at this moment: myotis21:~# nfsstat Client rpc stats: calls retrans authrefrsh 414528349 885 37 Client nfs v3: null getattr setattr lookup access readlink 0 0% 95673837 23% 3961938 0% 89586364 21% 110097351 26% 2930961 0% read write create mkdir symlink mknod 20009850 4% 6065319 1% 3757720 0% 1557 0% 0 0% 0 0% remove rmdir rename link readdir readdirplus 6378134 1% 281 0% 2602358 0% 555097 0% 53126619 12% 15615402 3% fsstat fsinfo pathconf commit 113256 0% 26152 0% 0 0% 4026151 0% and this is the same on one of the new ones: amateo_adm@myotis31:~$ nfsstat Server rpc stats: calls badcalls badclnt badauth xdrcall 0 0 0 0 0 Client rpc stats: calls retrans authrefrsh 178040318 675 178040800 Client nfs v3: null getattr setattr lookup access readlink 0 0% 24350345 13% 5045924 2% 10939469 6% 30185146 16% 142865 0% read write create mkdir symlink mknod 8818016 4% 6058614 3% 2877653 1% 420 0% 0 0% 0 0% remove rmdir rename link readdir readdirplus 2842562 1% 69 0% 2961239 1% 634038 0% 0 0% 82921863 46% fsstat fsinfo pathconf commit 70861 0% 18754 0% 9377 0% 152702 0% Although nfs configuration is the same, there are a lot of differences on readdir vs readdirplus nfs operations. In fact, in the old one we have 12% readdir operations and 3% of readdirplus. And in the new one we have 46% of readdirplus and no readdir operations. Although readdirplus is supposed to be an optimization in nfs3, in situations when you have big directories and uses just a few entries of these directories it could be worse. So we think if this could be the problem (or one of them). Any idea of this difference? And if this difference could be significative? PS: I have attached doveconf -n of the new server. -- Angel L.

[Dovecot] Dovecot mailstorage migration uppon logging / delivery with dsync
by Xavier Beaudouin 05 Jul '12

05 Jul '12

Hi there, I have a pretty standard setup with "simple" dovecot 2,0 configuration (eg /var/mailboxes on NFS with old netapp) and local ldap directory and Maildir. I wanted to find a good way to migrate from NFS old netapp to NFS new server (this one is not a netapp !). There 3 kind way (according to my own experience) - rsync old spool to new spool being patient stop services and then doing last rsync and mount /var/mailboxes mount point from old netapp to new nfs server). - doing imap_login (and other stuff like this) doing an rsync per box AFTER doing the first rsync with all boxes... - using dsync to fetch the maildir stuff from old server to new one, doing a simple flag, and doing "au fil de l'eau" migration. The last one seems to me a good idea, but I cannot figure host to make this correctly. Any hints or do someone here has already done this kind of stuff? Kind regards, -- Xavier Beaudouin

[Dovecot] Migration Question

Hi all I got a shiny new server and I want to install the latest and greatest of everything on it. The old server has dovecot-1.2.17 working with postfix-2.8.4,1, dovecot quotas, sieve etc. My question is: Would it work of I installed dovecot 2 on this server along with everything I want and just copy the /home/virtualmail directory where all the user mail directories are? I use the Maildir format by the way.

[Dovecot] Outlook 2010 very slow when using IMAP - are there any tweaks?
by Kaya Saman 03 Jul '12

03 Jul '12

Hi, though this is a bit of a side question, has anybody had an issue while running Outlook 2010 with Dovecot? The reason why I am asking is that I have setup a Dovecot 2.1.7 server on FreeBSD which works fantastically with Thunderbird but Outlook seems to be twice as slow in transferring information across?? # dovecot -n # 2.1.7: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.2-RELEASE amd64 auth_debug = yes auth_mechanisms = plain ntlm login auth_use_winbind = yes auth_username_format = %n auth_verbose = yes auth_winbind_helper_path = /usr/local/bin/ntlm_auth disable_plaintext_auth = no info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_gid = mail_user mail_home = /mail/AD_Mail/%Ld/%Ln mail_location = maildir:~/Maildir mail_uid = mail_user passdb { args = failure_show_msg=yes driver = pam } pop3_fast_size_lookups = yes pop3_lock_session = yes pop3_no_flag_updates = yes protocols = imap pop3 ssl = no userdb { driver = static } Since (like most corporate organizations out there) we solely run Outlook coupled to Exchange, this excersize was meant to be a way of getting rid of PST files. We don't run out own Exchange however, and don't have any control over it either. My workaround was to simply use the Outlook GUI space to transfer emails between Exchange and Dovecot running the IMAPv4 protocol. For whatever reason Outlook is being really garbage about dealing with stuff and since I don't know Outlook or MS products very well (being your typical average OpenSource guy) I was wondering if there were any tweaks that could be made within Outlook to speed it up or in Dovecot to work better with Outlook? I guess one could get sidetracked into the argument of mdbox vs. Maildir from my config however, Thunderbird is really fast and transfers large amounts of data really easily. Reaches round 130Mbps using nload performance grapher, while Outlook only manages ~50kbps but spikes at 2-3Mbps on occassion. Can anyone offer any guidence or assistance in this matter?? Actually wherever I run Dovecot, including my servers at home, it is fast and reliable. Yes I know MS is the polar opposite of anything worth using however, my company won't change and I'm stuck banging my head against the wall while trying to get MS to interface with ANYTHING.....

[Dovecot] Problem with 'doveadm mailbox status -t' reporting cumulative vsizes after upgrading from v2.0.16 to v2.1.7
by Jase Thew 03 Jul '12

03 Jul '12

Hi, I upgraded from Dovecot v2.0.16 to v2.1.7 over night and I noticed this morning that one of my daily reports which lists summarised mailbox sizes per user has started listing nonsense for vsizes. The reporting script at its core calls : doveadm -f flow mailbox status -A -t 'messages vsize' '*' It appears that Dovecot 2.1.7 is not resetting the vsize after collating the sum total of mailboxes sizes for each user, so that vsize just constantly increases as it iterates over each user. Eg: # doveadm -f flow mailbox status -A -t 'messages vsize' '*' accounts(a)example.com messages=1 vsize=759 adam(a)example.com messages=0 vsize=759 amy(a)example.com messages=24 vsize=51699697 andy(a)example.com messages=5446 vsize=3220940815 anna(a)example.com messages=50 vsize=3224035563 careers(a)example.com messages=1 vsize=3224036311 craig(a)example.com messages=2471 vsize=4421343199 creative(a)example.com messages=189 vsize=4426884182 david(a)example.com messages=8 vsize=4440729729 davidw(a)example.com messages=0 vsize=4440729729 enquiries(a)example.com messages=1 vsize=4440730491 gemma(a)example.com messages=4109 vsize=6349098844 gin(a)example.com messages=86 vsize=6392599904 holly(a)example.com messages=2000 vsize=7200342663 ian(a)example.com messages=0 vsize=7200342663 info(a)example.com messages=4 vsize=7200558689 jackie(a)example.com messages=2 vsize=7200721146 jade(a)example.com messages=137 vsize=7210548548 jake(a)example.com messages=16667 vsize=15260532446 katie(a)example.com messages=1 vsize=15260533375 mark(a)example.com messages=0 vsize=15260533375 mike.a(a)example.com messages=9 vsize=15261474205 mike.s(a)example.com messages=296 vsize=15314352543 mike(a)example.com messages=6357 vsize=20631446344 nick(a)example.com messages=1184 vsize=21038046728 social(a)example.com messages=65 vsize=21038935461 will(a)example.com messages=85 vsize=21057572390 [SNIP] The same occurs with -u '*(a)example.com' in place of -A, and also for 'all' in place of 'messages vsize'. Is this expected behaviour in 2.1.x compared to 2.0.x, or have I stumbled upon a bug? Regards, Jase Thew.

[Dovecot] Dovecot shared library to replace libc-client
by Asheesh Laroia 03 Jul '12

03 Jul '12

Hi all Dovecotters, Lots of programs (e.g, PHP) link to a library called c-client, which is a derivative of the original IMAP implementation, UW IMAP. (For those new to UW IMAP, read here: http://www.washington.edu/imap/ ) UW IMAP is not in as much of active development as it used to be, so I am curious: I see there is a dovecot shared library. I haven't looked into the details, but here are things I'm interested in: 1. Replacing libc-client's use as a client library In Debian, for example, you can search for packages that depend on this library as a client. It looks like this: $ ~ apt-cache rdepends libc-client2007e libc-client2007e Reverse Depends: uw-mailutils uw-imapd libc-client2007e-dev ipopd prayer php5-imap mailsync libmail-cclient-perl asterisk aolserver4-nsimap uw-mailutils libc-client2007e-dev prayer php5-imap mailsync libmail-cclient-perl asterisk-voicemail-imapstorage Let's say, hypothetically, we wanted to switch php5-imap to using Dovecot where it currently uses libc-client. I envision creating libdovecot-c-client-alike that is a set of headers and a library that is API-compatible with (at least a subset of) c-client. You can call that a "compatibility shim." Then e.g. php5-imap could be given the path to those headers and the corresponding libdovecot-c-client-alike library, and when it thinks it is linking to c-client, it could instead link to the libdovecot-c-client-alike. This might be convenient if you want to limit how much of a public API is presented by the current "dovecot.so" that gets installed in e.g. /usr/lib/dovecot/. The compatiblity shim could have a small API, and if you don't want provide ABI guarantees within dovecot.so, the shim could dlopen() dovecot.so rather than link to it. 2. Use of Dovecot shared library within alpine, embedding the imapd Right now, the mail client "alpine" embeds a copy of the UW IMAP source. It uses this when accessing local mail spools, for example. If Dovecot's IMAPd were available as a shared library, perhaps with a c-client-like API, (although not necessarily -- it would be feasible to upgrade alpine to a different API), then alpine could use Dovecot's mail drivers directly. So, those two are the dream. Timo and others, what are your thoughts? Thanks for reading this far! -- Asheesh. P.S. The radical request #2 would be an excellent, decisive way to end a sad thread in the Debian bug tracker about Alpine + Maildir: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=405762 .

[Dovecot] v2.1.8 released
by Timo Sirainen 03 Jul '12

03 Jul '12

http://dovecot.org/releases/2.1/dovecot-2.1.8.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.8.tar.gz.sig Most importantly fixes a pretty bad behavior of sending mailbox names as UTF-8 instead of mUTF-7 as required by IMAP RFC. I'm surprised nobody hadn't noticed this in v2.1.x tree before yesterday. I guess some clients might have translated the name to UTF-8 anyway and not noticed it, while others would have silently ignored the problem of not seeing STATUS updates. + pop3c: Added pop3c_master_user setting. - imap: Mailbox names were accidentally sent as UTF-8 instead of mUTF-7 in previous v2.1.x releases for STATUS, MYRIGHTS and GETQUOTAROOT commands. - lmtp proxy: Don't timeout connections too early when mail has a lot of RCPT TOs. - director: Don't crash if the director is working alone. - shared mailboxes: Avoid doing "@domain" userdb lookups. - doveadm: Fixed crash with proxying some commands. - fts-squat: Fixed handling multiple SEARCH parameters. - imapc: Fixed a crash when message had more than 8 keywords. - imapc: Don't crash on APPEND/COPY if server doesn't support UIDPLUS.

[Dovecot] Additional passdb result status
by Jürgen Pabel 03 Jul '12

03 Jul '12

Dear Dovecot-Team, I am implementing a plugin (for the pop3/imap process) that requires some data to provided from the authentication phase (a derivative of the password). For that, I have now implemented a passdb plugin that generates this data and I would like to "pass" this data down to the mail process (pop3/imap) via extra_fields in the reply of the authentication. The general idea is that my custom passdb plugin calculates the data, sets the extra_field and returns some error (authentication was not successful) so that the "real" passdb backend can be invoked to "really" validate the authentication data. However, in auth_request_handle_passdb_callback() the extra_fields are reseted unless the return code is PASSDB_RESULT_USER_DISABLED. But if that return code is used then any following passdb's aren't invoked any more - which makes sense with respect to user authenticiation. I would therefore like to propose that some IGNORE/CONTINUE-status to be introduced in auth/passdb.h, that would be handled in that extra_fields and possible other values are not reseted in order to allow such propagation of data from authentication process down to the mail process (which could be extracted from the reply string by parsing it). As a further implementation alternative (to the parsing of the reply string), I also propose that some new "environment" item be introduced (in auth_request) in order to allow such data passing in a generic manner. I hope you consider my proposal to be reasonable. If desired, I could implement this myself and provide a patch for merging (based on 2.0.x). If my proposal is generally unfavored, it would be great if any alternative approaches for my situation were suggested. Thanks. Regards, Jürgen PS: please reply to my e-mail (or CC me), as I have not subscribed to the dovecot list

Hello everybody, I am running debian wheezy for development and test, and I recently upgrade to dovecot 2.1.7 I am using LDAP lookups, and virtual users with the same UID/GID. Everything was working fine before, but now, I have this error when I try to send an email to a local account: -------------------------------------------------------- Jun 26 15:46:52 lapetus dovecot: lmtp(24518): Error: user user.test(a)indienet.com: Auth USER lookup failed Jun 26 15:46:52 lapetus dovecot: auth: Error: userdb(user.test(a)indienet.com,127.0.0.1): client doesn't have lookup permissions for this user: userdb reply doesn't contain uid (change userdb socket -------------------------------------------------------- However, even if I set the permissions to 0666, I still have the same error.

Hello everyone, I'm using the very good imaptest [0] tool to test my little imap server implementation.

[Dovecot] Setting up mixed mbox and maildir
by Jonathan Ryshpan 03 Jul '12

03 Jul '12

I'm trying to set up a dovecot server for which mail arrives in an mbox, and mail is stored in a maildir. The wiki (see http://wiki.dovecot.org/Namespaces) refers to this as "Mixed mbox and Maildir". It advises handling this situation by creating two namespaces: one for the mbox and the other for the maildir. Each of these namespaces starts with namespace private { On the other hand the sample configuration in the documentation puts inbox in a namespace starting with: namespace inbox { # Namespace type: private, shared or public #type = private It appears that there has been a change in the configuration syntax after the wiki was written, and that the word following namespace no longer gives a property of the namespace, but rather its name. Is this correct? In any case, how should the configuration be modified to handle mixed mailboxes? Thanks - jon

[Dovecot] Proxy config help please
by Zac Israel 03 Jul '12

03 Jul '12

Hello, I am new to dovecot and I am initially trying to setup a basic imap proxy with password forwarding, I can start the dovecot service, connect and give it my password, and that is where I hang. My config is: root@imap-test:/etc/dovecot# doveconf -n # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-24-generic x86_64 Ubuntu 12.04 LTS auth_debug = yes auth_verbose = yes debug_log_path = syslog first_valid_uid = 100 imap_capability = CAPABILITY IMAP4rev1 ACL BINARY CATENATE CHILDREN CONDSTORE ENABLE ESEARCH ESORT I18NLEVEL=1 ID IDLE LIST-EXTENDED LIST-STATUS LITERAL+ LOGIN-REFERRALS MULTIAPPEND NAMESPACE QRESYNC QUOTA RIGHTS=ektx SASL-IR SEARCHRES SORT THREAD=ORDEREDSUBJECT UIDPLUS UNSELECT WITHIN XLIST last_valid_uid = 200 mail_debug = yes mail_gid = 107 mail_uid = 107 passdb { args = proxy=proxy_always nopassword=y host=172.16.0.13 port=143 proxy_timeout=5 starttls=y ssl=any-cert driver = static } protocols = imap service imap-login { inet_listener imap { address = * port = 143 } } ssl = required ssl_cert = </etc/courier/imapd.pem ssl_key = </etc/courier/imapd.pem verbose_ssl = yes The system at 172.16.0.13 is a zimbra proxy. I can see in the logs that it initially complains about my ssl cert, and if I remove ssl=any-cert it fails because my cert is self signed, so I know it is talking to the proxy and doing starttls which is a requirement of zimbra. Unfortunately I have not found a way to see the full exchange between dovecot and my zimbra proxy other than tcp dump, which just shows a small packet exchange. Please let me know if I can provide any other information and thanks in advance for any help. -Zac

[Dovecot] Dovecot 2.1 stable packages for Debian?
by Krzysztof Trybowski 02 Jul '12

02 Jul '12

Hello all, it is strange, but Dovecot 2.x still didn't make it into Debian (not even backports). It exists in testing, but that's still a long wait. OTOH there are official packages built every day (referenced from the download page). This puzzles me: why isn't there a build created from each stable, released version of Dovecot, so that users of Debian Stable could benefit from the new version, and run it on production environment? Could you (I mean — the Dovecot team) provide such packages? This wouldn't require any major amount of work, since you already have daily builds produced. You would just have to run that building system once per each released version and keep it available for download. The reason for this is relatively simple: I'm about to implement a new mail server, and I'd like to keep to Debian Stable while using Dovecot 2.x. This will make future updates much easier, as I won't have to face 1.2 -> 2.0 migration on a production system. Regards, KT

[Dovecot] RAID1+md concat+XFS as mailstorage
by Костырев Александр Алексеевич 02 Jul '12

02 Jul '12

Hello! somewhere in maillist I've seen RAID1+md concat+XFS being promoted as mailstorage. Does anybody in here actually use this setup? I've decided to give it a try, but ended up with not being able to recover any data off survived pairs from linear array when _the_first of raid1 pairs got down. thanks!

[Dovecot] [PATCH] GSSAPI authorization and virtual users
by Sam Morris 02 Jul '12

02 Jul '12

The attached patch makes it possible for Kerberos principals to be associated with a password database entry by adding a new "k5principals" passdb setting. A client that successfully authenticates using GSSAPI will be able to log in as any user who has been associated with the client's Kerberos principal. This means that users can now use their Kerberos identities to access virtual mail accounts. The patch definitely needs review by someone familiar with Dovecot. It works for me on a small test installation using the passwd-file backend. Things that should probably be improved: 1. The list of authorized principals is stored in struct auth_request. I would prefer to store it in struct gssapi_auth_request, but auth-request.c does not know about structs that are specific to the different authentication plugins. This could be fixed in a more general way by adding a new function to struct mech_module to allow authplugins to read fields during passdb lookups. 2. The gssapi authplugin now does a credential lookup in order to trigger parsing of the k5principals setting. In order for this to work, auth_request_set_username is now called before mech_gssapi_userok. AFAICT the only impact of this is that messages logged by this function (and the functions it calls) will now use the name of the virtual account. 3. The credentials lookup triggers an info log message saying that credentials for GSSAPI were requested, "but we have only (e.g.) MD5-CRYPT". The authplugin doesn't actually want the credential, but I think that the only way the authplugin can trigger a passdb lookup is by requesting it. 4. The final part of the code in mech_gssapi_unwrap was moved to the callback that's triggered when the credentials lookup is complete. The code still needs access to the GSSAPI data, so the buffer pointer & length are now stored in struct gssapi_auth_request, making the inbuf parameter to the mech_gssapi_{sec_context,wrap,unwrap} functions superfluous. The parameters should be removed. 5. The k5principals list won't be processed on Solaris. The code added to the end of mech_gssapi_krb5_userok would have to be moved to a separate function and then be called from the Solaris code. 6. GCC tells me about assignment to incompatible pointer types in the code that iterates through gssapi_k5principals. I must be missing something. The patch is licensed under the MIT license. Please let me know what you think. -- Sam Morris <sam(a)robots.org.uk>

[Dovecot] UTF-8 mailbox name STATUS response
by Ewald Dieterich 02 Jul '12

02 Jul '12

STATUS in Dovecot 2.1.7 returns the UTF-8 decoded folder name in a string literal: . CREATE "INBOX.Euro &IKw-" . OK Create completed. . LIST "" "INBOX.Euro &IKw-" * LIST (\HasNoChildren) "." "INBOX.Euro &IKw-" . STATUS "INBOX.Euro &IKw-" (MESSAGES) * STATUS {14} INBOX.Euro € (MESSAGES 0) . OK Status completed. Is this intended? My Perl script based on Mail::IMAPTalk doesn't like it and I wonder if there are other clients that don't cope with it.

[Dovecot] lmtp proxy timeout while waiting for reply to DATA reply
by Daniel Parthey 02 Jul '12

02 Jul '12

Hi, we are experiencing similar sporadic data timeout issues with dovecot 2.0.20 as in http://dovecot.org/pipermail/dovecot/2011-June/059807.html at least once a week. Some mails get temporarily deferred in the postfix queue since dovecot director lmtp refuses them and the mails are delivered at a later time. The problem applies to mails delivered to single users as well as distribution lists where the mails gets delivered to several mailboxes by postfix. The postfix log shows the following output: postfix.log.7.gz:Apr 21 18:48:46 10.129.3.233 postfix/lmtp[15868]: 88062C08E: to=<username(a)example.org>, orig_to=<username(a)example.org>, relay=127.0.0.1[127.0.0.1]:20024, delay=35, delays=5.4/0.01/0/30, dsn=4.4.0, status=deferred (host 127.0.0.1[127.0.0.1] said: 451 4.4.0 Remote server not answering (timeout while waiting for reply to DATA reply) (in reply to end of DATA command)) The dovecot.log (mailbox and director log there via syslog) shows the following output: Apr 21 18:46:53 10.129.3.233 dovecot: lmtp(15869): Debug: none: root=, index=, control=, inbox=, alt= Apr 21 18:46:53 10.129.3.233 dovecot: lmtp(15869): Connect from 127.0.0.1 Apr 21 18:46:53 10.129.3.233 dovecot: lmtp(15869): Debug: auth input: user=username(a)example.org proxy port=19024 host=10.129.3.190 proxy_refresh=450 Apr 21 18:46:53 10.129.3.233 dovecot: lmtp(15869): Disconnect from 127.0.0.1: Client quit (in reset) Apr 21 18:47:29 10.129.3.233 dovecot: lmtp(15869): Debug: none: root=, index=, control=, inbox=, alt= Apr 21 18:47:29 10.129.3.233 dovecot: lmtp(15869): Connect from 127.0.0.1 Apr 21 18:47:29 10.129.3.233 dovecot: lmtp(15869): Debug: auth input: user=username(a)example.org proxy port=19024 host=10.129.3.190 proxy_refresh=450 Apr 21 18:47:29 10.129.3.233 dovecot: lmtp(15869): Disconnect from 127.0.0.1: Client quit (in reset) Apr 21 18:48:15 10.129.3.233 dovecot: lmtp(15869): Debug: none: root=, index=, control=, inbox=, alt= Apr 21 18:48:15 10.129.3.233 dovecot: lmtp(15869): Connect from 127.0.0.1 Apr 21 18:48:15 10.129.3.233 dovecot: lmtp(15869): Debug: auth input: user=username(a)example.org proxy port=19024 host=10.129.3.190 proxy_refresh=450 Apr 21 18:48:46 10.129.3.233 dovecot: lmtp(15869): Disconnect from 127.0.0.1: Client quit (in reset) One cannot identify the lmtp log origin from the log_format prefixes, but it seems that the "lmtp($PID)" log originated from the director, since proxy port 19024 is mentioned in the logs, which is our dovecot mailbox backend. Config for dovecot (mailbox) and director (proxy) is attached. mail_debug is yes for both dovecot and director. How can we find out more information? Shall I apply the following patches from http://dovecot.org/pipermail/dovecot/2011-June/059987.html or are they already included with version 2.0.20? Regards, Daniel

[Dovecot] director directing to wrong server (sometimes)
by Angel L. Mateo 02 Jul '12

02 Jul '12

Hello, I have discovered a strange behaviour with director proxying... I have a user, its assigned server is 155.54.211.164. The problem is that I don't know why director sent him yesterday to a different server, because my server was up all the time. Moreover, I'm using poolmon in director servers to check availability of final servers and it didn't report any problem with the server. I have two load balanced director servers.

[Dovecot] Config off by a nuance or a gross?
by Michael Brian Bentley 01 Jul '12

01 Jul '12

Hi, I am trying to establish an IMAP mail service accessible using a current Thunderbird on a laptop. I used Macports to install Dovecot2 (2.1.5) on an older Snow Leopard Mac mini with Intel Core Duo (specifically a Macmini1,1). My goal is to be able to run sieve under dovecot2 and offload the email triage from my work laptop to the little mail server. Mail appears to show up on the server just fine. I'm having trouble getting Tbird to log in and access properly. Because there are so many components in play (Tbird, pam, Dovecot2, macports, OS X Snow Leopard 10.6.8) (dovecot by itself seems to have quite a few settings), it is hard to tell what bit is out of whack. The message I get from Tbird 13.0.1 for OS X (on Lion) is: Alert: The IMAP server bentley on TheMini does not support the selected authentication method. Please change the 'Authentication method' in the 'Account Settings | Server settings'. When I set up the account, Tbird's automatic configuration invents a fake mail service based on my domain name, but appears to configure things sensibly once I switch to the manual configuration and fill in the relevant IP information. It does not appear to care whether it has a password or not. When I set up the account manually on TBird, I let it set up as: IMAP (ipv4)xx.xxx.xx.xx Port: 143 Connection security: None Authentication method: Password, transmitted insecurely SMTP xxxxxxxx.com Port: 587 The dovecot.conf tree includes these: passdb { driver = pam } userdb { driver = passwd } default_login_user = _dovenull default_internal_user = _dovecot service imap-login { executable = /opt/local/libexec/dovecot/imap-login inet_listener imap { address = * port = 143 } } service imap { executable=/opt/local/libexec/dovecot/imap process_limit = 1024 } service lmtp { unix_listener lmtp { } } Issuing the command: dovecot --build-options produces: Build options: ioloop=kqueue notify=kqueue ipv6 openssl io_block_size=8192 Mail storages: shared mdbox sdbox maildir mbox cydir imapc pop3c raw SQL drivers: Passdb: checkpassword pam passwd passwd-file Userdb: checkpassword passwd prefetch passwd-file The /etc/pam.d/dovecot file contains: # pop3, imap, smtp : auth account password session auth required pam_opendirectory.so account required pam_permit.so password required pam_deny.so session required pam_permit.so Dovecot provides the following debug messages on the console when I add args = failure_show_msg=yes to passdb in the relevant dovecot conf file: Jul 1 11:12:38 xx-xxx-xx-xx-nerewhon dovecot[3871]: auth: Debug:auth client connected (pid=5047) Jul 1 11:12:40 xx-xxx-xx-xx-nerewhon dovecot[3871]: imap-login: Disconnected (no auth attempts in 2 secs): user=<>, rip=192.168.xx.xx, lip=xx.xxx.xx.xx I recently discovered doveadm and used it with: doveadm config to create what I think is the current dovecot.conf file. I hesitate to inflict that on the list without being told, "yeah, we need that," there may be digest subscribers out there...

[Dovecot] ot: trying to understand log entries, etc
by Voytek Eymont 01 Jul '12

01 Jul '12

totally of, I'm trying to understand what's happening, aka, 'how does email works' ? I have Dovecot 1.x, all works fine I noticed in the logs failed access from no-longer-hosted account/user, physical account deleted/removed, most likely from user's BBerry, every ~15 minutes: from /var/log/maillog --- Jun 24 07:31:25 dovecot: imap-login: Disconnected: Inactivity (auth failed, 1 attempts): user=<vvv@tld>, method=PLAIN, rip=101.222.222.222, lip=111.111.111.111 --- I recreated account/physical path /var/mail/.../tld/vvv@tld I logged in with webmail, all works, webmail logged out I physically copied some emails (from another account) to physical path ../../tld/vvv@tld/new after a while, I see the email files NO LONGER in ../../../new BUT now in ../../tld/vvv@tld/cur Q: that means the email was accessed, doesn't it ? BUT, I don't see any more access in the /var/log/maillog, not failed, not OK I did see one, after I recreated account Jun 30 20:01:53 dovecot: IMAP(vvv@tld): Disconnected: Logged out bytes=32/666 NONE since, but email files move from new to cur ?? if I observe email files moving from 'new' to 'cur' shouldn't I see some action logged in /var/log/maillog to correspond ? perplexed.... -- Voytek

hi.. im planning to move my Mailserver from an FreeBSD Box to an Ubuntu 12.04 LTS Box. Both Boxes run Dovecot 2.0 Does anyone did this before and experienced any problems ? Downtime is no problem, my plan is to stop Dovecot on the Bsd Box and copy all Mailbox files to the Uuntu system and start dovecot. Regards Hans

Log message "lda(rolf)" looks like this happens. To summarize, I think LMTP will be the easiest way to fix the permission problems. Otherwise you would need to fiddle out how to prevent dovecot lda from switching to group additional group "mail", since unprivileged user "rolf" is not allowed to do that.

[Dovecot] how to announce shared folders to clients using non-default mail prefix
by Tom Lieuallen 30 Jun '12

30 Jun '12

We're using dovecot 2.1.3 and I've been doing some testing with 2.1.7. We have shared mail (maildir) folders working along with our default mbox mailboxes. Our problem is trying to get this to work in a reasonable fashion with our iPhone or iPad mail.app clients. It's well known that they don't honor the subscription list; they show all available mail folders and do not collapse trees of folders. I have 381 folders in directories under mail. Normal clients are fine, but this is unmanageable in IOS. What we have been doing is changing the mail prefix for the iPhone to a subfolder, then using soft links to point to the most commonly used folders we use. This works, but when one changes the mail prefix, any shared folders are not presented. I'm suspicious that this is a design decision. If there is some way to make it work, I'd be very grateful. Note the two 'sharedimap' folders listed in the first 'list'. Note that if I change the prefix for that shared namespace to 'iphonemail/', it does present my shared folders as well as anything in a personal iphonemail directory. However, 'select' didn't work with the personal folders. My guess is it's mostly due to the difference in mail formats between the two (mbox & maildir). But, it does show that somewhere in the code it's checking the mail prefix against namespaces and not displaying shared folders in non-default prefixes. I wish this were a configurable option. thank you Tom Lieuallen Oregon State University . list "" * * LIST (\Noselect \HasChildren) "/" "foo1" * LIST (\NoInferiors \UnMarked) "/" "foo1/folder1" * LIST (\Noselect \HasChildren) "/" "iphonemail" * LIST (\NoInferiors \Marked) "/" "iphonemail/foo1" * LIST (\NoInferiors \UnMarked) "/" "Sent" * LIST (\NoInferiors \UnMarked) "/" "Trash" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "sharedimap/cesupport" * LIST (\HasNoChildren) "/" "sharedimap/mimesupport" .

[Dovecot] Adding IMAP SORT and THREAD Extensions but THREAD=ORDEREDSUBJECT functionality to Dovecot 2.x.y !
by Oooo1 30 Jun '12

30 Jun '12

Hi. Can somebody add IMAP SORT and THREAD Extensions THREAD=ORDEREDSUBJECT function to the just next version of Dovecot ? It is necessary to GroupWare server. At the moment I have made it workable together, but there is one unstable point, as I have understood SOGo needs THREAD=ORDEREDSUBJECT sorting functions and if it not to get it, GroupWare server makes unworkable some of its component. If it needs additional info, you are welcome.

[Dovecot] What does "namespace inbox {..." mean
by Jonathan Ryshpan 30 Jun '12

30 Jun '12

I'm trying to set up a dovecot server for which mail arrives in an mbox, and mail is stored in a maildir. The wiki (see http://wiki.dovecot.org/Namespaces) refers to this as "Mixed mbox and Maildir". It advises handling this situation by creating two namespaces: one for the mbox and the other for the maildir. On the other hand the sample configuration coming with dovecot in my distro puts inbox in a namespace starting with: namespace inbox { # Namespace type: private, shared or public #type = private It appears from the wiki that the word following the namespace declarator (if this is the right word) should be either "public", "shared", or "private", and describes a property of the namespace being declared. So what does: namespace inbox {... mean? Similarly in another part of the wiki (see http://wiki2.dovecot.org/Plugins/Virtual) I read that it's possible to have namespace virtual { namespace real { ... which only increases my perplexity. Please advise! Thanks - jon

[Dovecot] Preferred LDAP Attribute for home/mail location
by Edgar Fuß 29 Jun '12

29 Jun '12

Is there, among the dovocot community, any preferred LDAP schema and attribute to use for setting the home/mail storage location? Some people seem to use the qmail schema, some a Jamm schema (whatever that is), and Markus Effinger has even created a dovecot schema (https://www.effinger.org/blog/2009/01/11/eigenes-ldap-schema-erstellen/) There may be more. I could even create my own given we have been assigned an official OID a decade ago anyway. However, sometimes I prefer to use what most other people do. I would effectively only need to store the name of the relevant NFS server.

Hi Kelsey, We're running ZFS here, and have just started using dovecot on it. No stats yet to report, but you might be interested in this edge case. One of our server started behaving badly... the database would randomly crash and not restart due to corrupted indexed. It turns out that the memory had gone bad, and that it had been bad for a while. Disk blocks were getting corrupted on read, and some on write! Luckly because we were on ZFS, which checksums all data, we were able to detect and repair most of the data (some 80mb of bad blocks distributed evenly thoughout the entire file system!) automatically, and also know exactly which files were unrecoverable (in the end just two or three files!). Also, we have hourly snapshots of all the file systems, so we were able to recover older versions of those files with minimal loss. I will never rely on a non-checksumming file system for production use again, for data that is existed to persist over time. Joe

[Dovecot] auth service: out of memory
by Mailing List SVR 29 Jun '12

29 Jun '12

Hi, I have some out of memory errors in my logs (file errors.txt attached) I'm using dovecot 2.0.19, I can see some memory leaks fix in hg after the 2.0.19 release but they seem related to imap-login service, I attached my config too, is something wrong there? Should I really increase the limit based on my settings? Can these commits fix the reported leak? http://hg.dovecot.org/dovecot-2.0/rev/6299dfb73732 http://hg.dovecot.org/dovecot-2.0/rev/67f1cef07427 Please note that the auth service is restarted when it reach the limit so no real issues, please advice thanks Nicola

[Dovecot] Integrating Dovecot with Amazon Web Services
by Gary Mort 29 Jun '12

29 Jun '12

I did some searching in the mail archives and didn't see any discussion of integration with AWS, so I wanted to through out my thoughts/plans and see if it has been done before. I am setting up my own personal website on EC2 along with an email server, and I really don't like the idea of using the disk drive as permanent mail storage. EBS is too small instance storage is ephermeral. Looking over the docs, the dbox format seems most easily copied for my needs. http://wiki2.dovecot.org/MailboxFormat/dbox To make life easy, I'll stick with just single-dbox as a start, however multi-dbox would be doable. With dbox, the only thing that I need to change is the alternate storage model: "An upshot of the way alternate storage works is that any given storage file (mailboxes/<folder>/dbox-Mails/u.* (sdbox) or storage/m.* (mdbox)) can only appear *either* in the primary storage area *or* the alternate storage area but not both — if the corresponding file appears in both areas then there is an inconsistency." First I want to add AWS S3 as a storage option for alternate storage. Then instead of the above model, the new model would be that email is always stored in alternate storage, and may be in primary storage. So, when mail comes in, I'd have Dovecot save the email to the alternate storage S3 bucket and update the indexs and other information[ideally, for convenience purposes, a few bits of relevant indexing information can be stored as metadata in the S3 object - sufficient so that instead of retrieving the entire S3 object, just the meta data can be pulled to build indexes. When a client attempts to retrieve an email message, Dovecot would check primary storage as it does now, if the message is not found than it will retrieve it from the alternate storage system AND store a copy in the primary storage. Primary storage can be periodically purged, have quota's to keep it from growing too large, etc. In this way, primary storage can be viewed as a message cache, just keeping the messages that are currently of interest, while S3 is the real data. [Ideally, this can be expanded so that when a message comes in, in addition to storing a copy in S3, an AWS SNS notification can be issued so if multiple IMAP servers are running, they can all subscribe to the same SNS channel and update themselves as needed]. This give me unlimited disk storage at S3 prices, I would even like to be able to set a few options based on the folder, so I can enable versioning on important message folders, use the even cheaper reduced redundancy storage for archives, and set expiration dates on email in the trash and spam folders so S3 will automatically purge the messages after a month. Secondly, I'd like to replace the Mysql database usage with a simpleDB database. While simpleDB lacks much of MySQL's sophistication, it doesn't seem that Dovecot is really using any of that, so simpleDB can be functionally equivalent. The primary purpose of using simpleDB is that this way the entire Dovecot system can be ephermeral. When a properly configured dovecot AMI is launched, it will start up, pull it's config data from an S3 bucket, subscribe to the SNS channel for new updates, and then start the Dovecot server. It won't care if it is the only Dovecot server, or if there are 500 other servers running. They all share the same simpleDB database. Whenever any change is made that is relevant to server configuration, a notice is generated to SNS, and all the email is stored in S3. As a starting point, I'm thinking the best place for me to start coding is the single-s3-dbox message store as it has the least moving parts[mainly just fix up the save function to run the way I need it to, and the retrieve function to make a local copy of any incoming email...additional metadata functionality can be added later]. Has anyone else been working on something similar? -Gary

[Dovecot] Mail migration to dovecot with doveadm backup
by Reinhard Vicinus 28 Jun '12

28 Jun '12

Hi, i try to migrate mails from a non dovecot imap server to a dovecot imap server with doveadm backup as described there: http://wiki2.dovecot.org/Migration/Dsync i first tried (local-mailbox port 18143 is the non dovecot imap server): /usr/bin/doveadm -o imapc_user=user(a)example.org -o imapc_password=imappw -o imapc_host=local-mailbox -o imapc_features=rfc822.size -o imapc_port=18143 -o mailbox_list_index=no -v -D backup -R -f -u user(a)example.org -m Sent imapc: and got the following error: dsync(user(a)example.org): Fatal: dsync backup: Looks like you're trying to run backup in wrong direction. Source is empty and destination is not. As the dovecot imap account is newly created and therefore empty it seams to try to backup from the dovecot imap server to the non dovecot imap server. So i tried instead: /usr/bin/doveadm -o imapc_user=user(a)example.org -o imapc_password=imappw -o imapc_host=local-mailbox -o imapc_features=rfc822.size -o imapc_port=18143 -o mailbox_list_index=no -v

[Dovecot] Default for non-present LDAP attributes?
by Edgar Fuß 28 Jun '12

28 Jun '12

With 1.2, is there a syntax to, for LDAP lookups, use a given fixed replacement for a non-present LDAP attribute? E.g. something that would extend user_attrs = mailFileServer=mail=maildir:/import/mail/%$/%d to use maildir:/import/mail/foo/%d in case the mailFileServer attribute is not present?

[Dovecot] Maildir Seen Flags not heeded when dovecot-shared present
by J E Lyon 28 Jun '12

28 Jun '12

Hi, After many hours of searching (!) and lots of testing procmail scripts, I found the explanation I was looking for -- something you explained at http://www.dovecot.org/list/dovecot/2008-July/032551.html That explains it. Thing is, though, every time I've seen shared mailboxes -- really shared by multiple staff or not -- the preference is in fact for the shared behaviours to also "share" the Seen flags. Typically, someone doesn't want to read an email that someone else has already picked up and started dealing with or responded to. (They'll file it in due course, but the Seen flag is the first indicator that someone's opened and started to deal with it.) Hacking source code and branching and whatnot isn't easy or done lightly, but I wondered if anything else had come to light in recent years about this issue. I'd be as happy getting my procmail script to tell Dovecot to update the index based on the flag, but I'm pretty sure that's not possible :) Any ideas greatly appreciated, thanks. ~ James.

[Dovecot] last hope... public namespace and directory structure
by Daniel Fischer 28 Jun '12

28 Jun '12

hello, I would like to migrate to dovecot, but I have a problem with a public namespace declaration: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-2-amd64 x86_64 Debian wheezy/sid And here are the relevant parts from the configuration: namespace { location = maildir:/var/mail/vhosts/%d/public prefix = Public. separator = . type = public } namespace inbox { prefix = separator = . subscriptions = yes type = private } I assume that all folders under ./public/ are public mailboxes. The public folder itself is not a maildir, but contains the team mailboxes i.e. ./public/.sales/ ./public/.service/ ./public/.purchase/ The file passwd for those 3 samples looks like this: sales@$DOMAIN::5000:5000::/var/mail/vhosts/$DOMAIN/public/.sales service@$DOMAIN::5000:5000::/var/mail/vhosts/$DOMAIN/public/.service purchase@$DOMAIN::5000:5000::/var/mail/vhosts/$DOMAIN/public/.purchase Note: All other users have mail_location /var/mail/vhosts/%d/%n Now a have the following problem: If I login in as user sales and create a folder foo and in there a folder bar. The directory structure is: ./public/. sales /.foo and /public/. sales /.foo.bar thats exactly what I´m expect. Now I logon as normal user. I can see the namespace Public with the sales mailbox but no subfolder foo or foo.bar. Now I create also the folders foo and in there bar, but the result is to me unexpected ;-): ./public/. sales ./public/. sales.foo ./public/. sales.foo.bar Looking forward to your comment, Daniel

[Dovecot] permissions on auth-userdb

Hi.. im still trying to upgrade to 2.0. Im getting: dovecot: lda: Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Permission denied (euid=10000(vmail) egid=10000(vmail) missing +r perm: /var/run/dovecot/auth-userdb, euid is not dir owner) the error is correct caus its owned by root. My Questions is who should own it ? Im not sure how that works, what process/user calls the auth-userdb ? The auth-userdb returns the args generated in master.conf, right ? i think comment out the user and group setting in master.conf will fix it but im not sure if that is the securest way. the mails come from postfix via dovecot-lda Hans master.conf service auth { # auth_socket_path points to this userdb socket by default. It's typically # used by dovecot-lda, doveadm, possibly imap process, etc. Its default # permissions make it readable only by root, but you may need to relax these # permissions. Users that have access to this socket are able to get a list # of all usernames and get results of everyone's userdb lookups. unix_listener auth-userdb { mode = 0600 #user = vmail #group = vmail } auth-ldap.conf.ext passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = static args = uid=vmail gid=vmail home=/home/MAILBOXES/%u/ mail=/home/MAILBOXES/%u/mail }

[Dovecot] The deleted_to_trash Plugin (workaround Outlook 2007 behaviour)
by J E Lyon 27 Jun '12

27 Jun '12

Hi, I see this plugin exists for v1 & v2, all very interesting... Surprised no one seems to have created an RPM and it looks like deleted_to_trash is one of the very few plugins to not be shipped as part of the default install with CentOS 5.5 or CentOS 6 (i.e. Dovecot v1 & v2 respectively.) Am I missing something, or does everyone really build from source? Thanks, James.

[Dovecot] pop3-throttle
by manu＠netbsd.org 27 Jun '12

27 Jun '12

Hello I am having a hard time with users using POP while leaving mailboxes of several gigabyte cumulated. This causes a lot of disk I/O and kills performancs for everyone. I try to encourage people migrating to IMAP, but that migration will take some time, and therefore I am looking for alterantive ways to workaround the problem. I found pop3-throttle-plugin.c, which seems a smart way to solve the problem, unfortunately it comes with no documentation. I was able to build it and load it, bu itsays nothing in the logs. Is there any doc somewhere? Any advices on how to set it up? -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz manu(a)netbsd.org

[Dovecot] Hardware infrastructure for email system
by Michael Wessel 27 Jun '12

27 Jun '12

Hi, I'm currently (re-)planning my email setup and have been doing some research. I have done some searches and read several threads in the areas of my questions here. While there are some that come close I haven't yet been able to get all my questions answered. I currently run a postfix, dovecot & roundcube setup and have about 2000 active accounts. I have a separate SMTP server for outbound mail and auth is done against a separate LDAP server. In front of the POP/IMAP server I have another SMTP (4 in parallel actually) server that receives and filters inbound mail through a company specific, proprietary filter before the mail hits the POP/IMAP server. LDAP & SMTP servers are ESXi VMs. So right now both dovecot and roundcube run on the same box which is a Dell PE2950 with dual quad-core Xeon, 16GB RAM and 6 1TB disks in RAID 6, so only local storage using maildir. So far it's been holding up fine, but it's beginning to show signs of overload now. I also expect an increase in users over the next few months up to somewhere between 10 - 20,000 mail boxes. Hence the re-planning. My first priority in redesigning my setup is reliability. I definitely need something fail-save and as close to always on as possible. Next is performance. And while the budget is of course limited for the moment I'm setting that aside and will worry about that when the time comes. Now here is my question(s): In order to support up to 20,000 mailboxes (distributed over several times-zones so they won't all be used at the same time) with a very reliable service with good performance, what do I actually need? Do I need(ul) SAN or is it just a "would be nice to have"? If yes, why and what would be appropriate for my needs? Or will a setup with a few more servers like the ones I already have, using something like DRBD and distributing services (imap, http, spamd etc) onto different boxes do? I know I have more reading to do on all the different options out there, but would like some input from people that have experience in this area so I can focus on the stuff that's right for my situation.

[Dovecot] doveadm proxy kick in director setups
by Tom Pawlowski 27 Jun '12

27 Jun '12

Something I noticed on a 2.1.7 director test cluster (two directors, three backends): 'doveadm proxy kick user' will kick all connections for that user on that director only. Any additional connections on other directors will remain active unless the command is run on all directors. Are the proxy and director sub-commands intended to be separate and distinct in their operation? If so, then this makes sense, as a proxy isn't necessarily a director. Are there any plans for a proxy kick equivalent that would work across directors? -- Tom Pawlowski OIT-CSS System Administrator office: Hill 145 email: tompru(a)jla.rutgers.edu phone: (732) 445-2634

[Dovecot] director map and mysql
by Костырев Александр Алексеевич 27 Jun '12

27 Jun '12

hello! Is "doveadm director map" command suppose to work when I store "host" value in mysql table? It gives me nothing in output with no errors in log. I've successfully setup directors with static passdb, and decided to give a try setup with storing host value in mysql table. The proxying is actually working, I'm just unhappy with no output from "doveadm director map". on the other hand output from "doveadm director map" is not empty, when I configure my password_query not to return host from table. director's settings in dovecot.sql is: passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf } userdb { driver = sql args = /etc/dovecot/dovecot-sql.conf } director_servers = 192.168.5.125 director_mail_servers = 192.168.5.110 192.168.5.111 service doveadm { inet_listener { port = 24245 } } protocol doveadm { auth_socket_path = director-userdb } doveadm_proxy_port = 24245 in /etc/dovecot/dovecot-sql.conf at director there's password_query = SELECT \ NULL AS password,\ 'Y' as nopassword, \ 'Y' AS proxy, \ MBOX_NAME as user, \ host2 as host \ from M_MAILBOX \ where MBOX_NAME = '%u' user_query = SELECT \ MBOX_NAME AS username, \ MAIL_DIRECTORY as home \ from M_MAILBOX \ where MBOX_NAME = '%u'; iterate_query = select MBOX_NAME AS username from M_MAILBOX; backend's conf: service doveadm { inet_listener { port = 24245 } }

the configuration keyword "pop3c_master_user" mentioned in the dsync migration documentation (http://wiki2.dovecot.org/Migration/Dsync) does not work for dovecot 2.1.7. a config line like: "pop3c_master_user = cyrus" will produce this error: doveconf: Fatal: Error in configuration file /etc/dovecot/local.conf line 33: Unknown setting: pop3c_master_user it's not defined in: src/lib-storage/index/pop3c/pop3c-settings.* is this feature not enabled with intention? btw. another question: will 'doveadm backup' mirror all the IMAP ACL information? thanks martin

[Dovecot] Dovecot performance under high load (vs. Courier)
by email builder 27 Jun '12

27 Jun '12

Hi, We are building a new system that will support a large number of users (high volume, high concurrent usage, etc). We have played with Dovecot, but in most serious applications we have traditionally used Courier IMAP. It's my (lay) understanding that with indexing and perhaps other things in Dovecot, it might perform better than Courier in larger environments like this. Am I correct or is it less clear-cut? Any tips on making the migration (not migrating an existing system, I mean migrating our paradigm - things to consider, things to watch out for)? TIA

[Dovecot] Virtual users - what is better Maildir or mbox?
by Kaya Saman 26 Jun '12

26 Jun '12

Hi, I'm trying to configure a server to use SAMBA and Winbind to authenticate to Active Directory.... I managed to get this portion up and running even the Dovecot portion. For reference something similar to this guide: http://www.whitneytechnologies.com/?p=119 However PAM is slightly different: # cat /etc/pam.d/dovecot auth sufficient pam_krb5.so no_user_check validate account sufficient pam_permit.so This is what my dovecot.conf file looks like: # cat dovecot.conf # v1.2+: auth_use_winbind = yes auth_winbind_helper_path = /usr/local/bin/ntlm_auth protocols = imap # It's nice to have separate log files for Dovecot. You could do this # by changing syslog configuration also, but this is easier. log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot-info.log # Disable SSL for now. ssl = no disable_plaintext_auth = no # We're using Maildir format #mail_location = maildir:~/Maildir mail_location = mbox:/mail:INBOX=/mail/%u # Authentication configuration: auth_verbose = yes auth_debug = yes auth_username_format = %n auth_mechanisms = plain ntlm login userdb { driver = static # args = uid=501 gid=1001 home=/mail/%u args = home=/mail/%u driver = static } passdb { driver = pam args = failure_show_msg=yes } Now what I would like to know is, which is better for "virtual hosting" Maildir or mbox? Basically my requirement is that I would like to separate users via either individual folders and then put each user's mbox or Maildir in the created directory, or simply name each mbox or Maildir according to the user name. First up is this possible? Secondly, how would I go about doing it? My users are not allowed to login to the system outside of IMAP as it's a Mail only server. Currently I've been looking at many links: http://satish-linuxbug.blogspot.co.uk/2008/08/freebsd-with-active-directory… http://joseph.randomnetworks.com/2005/11/08/freebsd-users-and-groups-with-s… http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm http://wiki2.dovecot.org/Authentication/Mechanisms/Winbind http://wiki2.dovecot.org/TestInstallation http://wiki2.dovecot.org/VirtualUsers http://www.linuxmail.info/active-directory-dovecot-pam-authentication/ http://wiki2.dovecot.org/HowTo/SimpleVirtualInstall I'm running dovecot version 2.1.7 on FreeBSD 8.2 x64 RELEASE. The system is not being used as an MTA server meaning that only IMAP transfers are being done using MS Outlook then filtered by Thunderbird. Regards, Kaya

[Dovecot] dsync error: "Mailboxes don't have unique GUIDs"
by Jeff Gustafson 25 Jun '12

25 Jun '12

I'm getting an error backing up mailboxes. I'm using the mirror command: dsync -fvo mail_home=/home/users/bob mirror ssh vmail(a)10.1.4.1 dsync -o mail_home=/home/.incoming_mail_migrations/users/bob dsync-remote(vmail): Error: Mailboxes don't have unique GUIDs: 1ef6ee37c694894d783100000581a675 is shared by INBOX and INBOX dsync-remote(vmail): Error: command BOX-LIST failed dsync-local(vmail): Error: Worker server's mailbox iteration failed The mail user doesn't yet exist on the destination yet, thus the use of the mail_home parameter. I found a mailing list message where a person was having a similar problem but I couldn't find confirmation that the issue was resolved.

[Dovecot] specifying home/sieve/sieve_dir relative to mail_location
by Edgar Fuß 25 Jun '12

25 Jun '12

With 1.2, is it possible to specify home, sieve and sieve_dir relative to mail_location? I have mail_location = maildir:/import/mail/%n/:INDEX=/var/db/dovecot/indexes/%n and, in the plugin section, home = /import/mail/%n/home sieve = /import/mail/%n/dovecot.sieve sieve_dir = /import/mail/%n/sieve I would like to partially move users to another location (different file server) by using an LDAP entry. I know it's possible to specify everything relative to home, so I could probably use relative ~/../-type paths for mail_locatin etc., but that looks a bit awkward. The VirtualUsers/Home Wiki enty contains an example for relative paths user_attrs = .., mailDirectory=home=/var/vmail/%$ which I do not understand.

[Dovecot] 2.1.7 TLS issues
by Christian Rößner 25 Jun '12

25 Jun '12

Hi, I have an interesting problem: I am building dovecot packages for Ubuntu since 10.04. Never had bigger trouble with it. Now since 2.1.6 or 2.1.7 (I can not say more precisely), Thunderbird 10ESR and Outlook 2010 can no longer use 143/TLS correctly. Automx delvers 143/TLS and Outlook tells me that it can not create a secure connection. I changed automx to use 993/SSL and everything works. Under Thunderbird 10ESR, I get a box that tells me that I need to change settings. When I sent mail, TB told me that it could not copy the mail to the sent folder. I also changed to 993/SSL and everything is perfect. At the other and, Apples Mail.app and iOS devices work perfectly over 143/TLS. So my guess is that it has to do with OpenSSL. Did something change in dovecot concerning TLS? Can I change options in the built process? Thanks in advance -Christian Rößner --- Roessner-Network-Solutions Bachelor of Science Informatik Nahrungsberg 81, 35390 Gießen F: +49 641 5879091, M: +49 176 93118939 USt-IdNr.: DE225643613 http://www.roessner-network-solutions.com

[Dovecot] The deleted_to_trash Plugin (workaround Outlook 2007 behaviour)
by J E Lyon 24 Jun '12

24 Jun '12

Hi, I see the plugin exists for v1 & v2, all very interesting... Surprised no one seems to have created an RPM and it looks like deleted_to_trash is one of the very few plugins to not be shipped as part of the default install with CentOS 5.5 or CentOS 6 (i.e. Dovecot v1 & v2 respectively.) Am I missing something, or does everyone really build from source? Thanks, James.

[Dovecot] Dovecot Quotas in Version 2
by Brian Spraker 24 Jun '12

24 Jun '12

Hello all, Just upgraded from Ubuntu 10.04 to 12.04 on a server today and went through a few issues that I finally got corrected with many different services. However, one of them - I absolutely cannot figure out. I was using Dovecot 1 in Ubuntu 10.04 - but in Ubuntu 12.04, it has been upgraded to Dovecot 2. Finally managed to get the configuration to work and get it to use MySQL as the back-end authentication method (had to install the dovecot-mysql package). But, I cannot get quotas to work. The moment I uncomment a quota line, Dovecot fails to start. Would appreciate any help with this. I am not using any of the individual configuration files on the conf.d folder - simply the dovecot.conf and dovecot-sql.conf file. Here is a copy of those. You can see the one commented line (mail_plugins under imap) simply will not work - but yet the one under POP works (although I don't think it is used): base_dir = /var/run/dovecot/ disable_plaintext_auth = no first_valid_uid = 33 last_valid_uid = 33 listen = * log_timestamp = "%Y-%m-%d %H:%M:%S " mail_privileged_group = www-data passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { quota = maildir quota_rule = Trash:storage=100M } protocols = imap pop3 service auth { user = root } service imap-login { executable = /usr/lib/dovecot/imap-login } service imap { executable = /usr/lib/dovecot/imap } ssl = no userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { imap_client_workarounds = mail_plugin_dir = /usr/lib/dovecot/modules/imap # mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_uidl_format = %08Xu%08Xv } And for the dovecot-sql.conf file (passwords changed, of course): driver = mysql connect = dbname=horde user=<USER> password=<PASSWORD> host=localhost default_pass_scheme = PLAIN password_query = SELECT user_uid as user, user_pass as password FROM horde_users WHERE user_uid = '%u'; user_query = SELECT uid, gid, home, maildir, concat('maildir:storage=', quota) AS quota FROM horde_users WHERE user_uid = '%u'; I did not update the dovecot-sql.conf file at all - so I don't know if there maybe be some configuration issue with how it is pulling the quota limit from the database. Quotas are in bytes in the database. Certainly would appreciate any help with this. I went through the Dovecot Quota Configuration in the wiki but it wasn't any help - as I basically already have that line in the config file, but it will fail to start Dovecot. Thank you! Brian S.

[Dovecot] Problems getting auto create plugin to work
by Dr Josef Karthauser 23 Jun '12

23 Jun '12

Hi there, I've configured the 'autocreate' plugin (in v.2.1.6), but it doesn't appear to be working. Can someone help me work out how to work out why please? I've got this in my 20-imap.conf file: protocol imap { mail_plugins = $mail_plugins antispam autocreate } and this in my 90-plugins.conf file: plugin { autocreate = Trash autocreate2 = Spam autosubscribe = Trash autosubscribe2 = Spam ... etc } But, the spam does not get created upon login. I've restart dovecot and restarted my mail client, but there's no hint of an spam folder. Is there something else that I also need to do? Thanks, Joe

[Dovecot] Import from Evolution
by Jonathan Ryshpan 23 Jun '12

23 Jun '12

I need to import the mail database generated by the evolution mail reader into dovecot. Evolution stores its mail in maildir format (fully standards compatible, I think); I would be using the maildir format in dovecot. Is there anything in the wiki, etc. explaining exactly how to do this? Why do this? Evolution is hopelessly broken, and is not likely to be fixed in the forseeable future, and I would like to keep my mails in maildir form. Reviews of kmail are very bad, and thunderbird uses the mbox format for storage. Thanks in advance - jon

[Dovecot] cumulative userdb ?
by Benoit Branciard 22 Jun '12

22 Jun '12

in Dovecot 2.0, is it possible to have kind of "cumulative" multiple userdb ? that is, for all users: - extract some attributes (let's say: uid, gid, home) from a first userdb (Passwd for example), - an extract some other attributes (mail for example, but overwriting those from the first userdb in case of redundancy) from a second userdb (LDAP for example) ? This is *different* from the "multiple databases" setup described in http://wiki2.dovecot.org/Authentication/MultipleDatabases, where it is meant as "failover": the second database is looked up only if the user isn't found in the first database. -- Benoit BRANCIARD Service InfraStructures (SIS) - Direction du Système d'Information (DSI) Université Paris 1 Panthéon-Sorbonne Centre Pierre Mendès France B 406 - 90, rue de Tolbiac - 75634 Paris cedex 13 - France Tél : +33 1 44 07 89 68 - Fax : +33 1 44 07 89 66 Accueil tél. : +33 1 44 07 89 65 Assistance : assistance-dsi(a)univ-paris1.fr Web : http://dsi.univ-paris1.fr -- Ce message a ete verifie par MailScanner pour des virus ou des polluriels et rien de suspect n'a ete trouve.

[Dovecot] Dovecot LDA, Offlineimap and Sieve
by Johnny 22 Jun '12

22 Jun '12

Hi, I am trying to st up Offlineimap to use Dovecots LDA to be able to use Sieve for mail filtering, but am not sure how to get this working. I think the right way would be to use 'preauthtunnel' in .offlineimaprc and try the setup below, which doesn't work. ,----.offlineimaprc | [Repository LocalRepository] | type = IMAP | preauthtunnel = ssh -q localhost '/usr/libexec/dovecot/deliver -d myloginid' `---- If I go via the network card, the snch is fine, but Sieve can't be used? ,---- | [Repository LocalRepository] | type = IMAP | preauthtunnel = MAIL=maildir:$HOME/Maildir/myMailDir /usr/libexec/dovecot/deliver -d mylogonid | remotehost = localhost | port = 143 | remoteuser = mylogonid | remotepass = mypassword `---- Has anyone got any tips on how to get offlineimap to send mail to Dovecot in a way that Siev3e can be used? thanks! -- Johnny

[Dovecot] LDA vs maildrop... LDA *and* maildrop?
by email builder 22 Jun '12

22 Jun '12

We're considering a move from Courier to Dovecot. So far, looks like it's not too bad, but the most challenging obstacle is what to do about our local delivery. Factors: 1. we use a lot of maildrop "features" that are impossible in sieve without piping to an external program (would rather not re-write our working maildrop scripts in another language) 2. would love to try dbox 3. we use IMAP/Maildir++ quotas (looks like with a little finesse it's possible to get maildrop and dovecot to play nice on this account, yes?) I saw it suggested to just call LDA from maildrop for any maildrop "to" commands (hmmm, what about "cc"?) here: http://article.gmane.org/gmane.mail.imap.dovecot/56120 How much overhead will this take? Would it be possible or advisable to use LMTP instead if that would help? Is this idea just too crazy?

[Dovecot] Manual manipulation of Sieve files
by email builder 22 Jun '12

22 Jun '12

We have some scripts that take care of some tasks when creating new email accounts, such as creating some default mail filter rules. I know Sieve scripts are plain text files, but need to be compiled for use. I see that you can use seivec to compile scripts manually, which can help me create .dovecot.svbin which can be placed where needed and permissioned correctly. But a couple questions: * Sieve has the concept of an active script - is this merely whatever is compiled into the .dovecot.svbin file? * Does dovecot (managesieve) do any other housekeeping when a user sieve script is installed and set as the active script? I would need to replicate this manually. * If the default script is always the same (sorry, for us, the solution isn't global scripts), would it work to compile that script once, keep the compiled version somewhere and merely copy it into the correct place for a new user? Are there issues with this? * Should we always have the plain text version along with the compiled one for proper managesieve operation going forward (users can edit their sieve scripts) Thank you

[Dovecot] Dovecot proxy/director and mail pop3/imap backend service on same server
by Aerion Stevens 22 Jun '12

22 Jun '12

Hi all, I am interested in running a Dovecot Proxy(with Director) on the same server as the main Dovecot IMAP/POP3 service. I have a basic Proxy/Director configuration working, however I am struggling with getting the Proxy and IMAP/POP3 service to coexist on the same server. I plan to use three IMAP/POP3 servers with a NFS/maildir backend, and I am playing with Dovecot 2.1.5 at the moment. I have two seperate configurations, one for the Proxy/Director and one for the Dovecot IMAP/POP3 "mail backend servers". For this to work my thoughts are that I will need to run the Proxy/Director imap/pop3 login process on the standard ports 143, 110, 993, 995 and for the Dovecot IMAP/POP3 mail backend service running on the same server will need to use different ports (I decided to be 9143, 9110, 9993, 9995 for example). How do I tell the director to proxy incoming imap/pop3 connection to the mail backend servers running on ports 9143, 9110, 9993, 9995 rather than the default imap/pop3 ports? Using the default ports will clearly cause loops. Can anyone kindly provide an example snippet of config that tells the director to use different port for IMAP and POP3 proxy? I have so far found the following pages helpful to what I am working on: http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy http://wiki2.dovecot.org/PasswordDatabase/ExtraFields http://wiki2.dovecot.org/Director Cheers, Aerion.

[Dovecot] GlusterFS + Dovecot
by Romer Ventura 22 Jun '12

22 Jun '12

Hello, Has anyone used GlusterFS as storage file system for dovecot or any other email system..? It says that it can be presented as a NFS, CIFS and as GlusterFS using the native client, technically using the client would allow the machine to read and write to it, therefore, I think that Dovecot would not care about it. Correct? Anyone out there used this setup?? Thanks.

[Dovecot] dovecot 2.1.5 performance
by Angel L. Mateo 21 Jun '12

21 Jun '12

Hello, I'm migrating from 1.1.16 running in 4 debian lenny servers virtualized with xenserver and 1 core and 5GB of RAM to 2.1.5 running in 4 ubuntu 12.04 servers with 6 cpu cores and 16GB of RAM virtualized with VMWare, but I'm having lots a performance problems. I don't think that virtualization platform could be the problem, because the new servers running in xenserver has the same problems than running in vmware. I have about 70000 user accounts, most of them without real activity (they are students who doesn't read his email or have its account redirected to other provider). I have about 700-1000 concurrent imap connections. I have storage in nfs (nfsv3, the nfs server is a celerra), but indexes are in local filesystems (each server has its own index fs). Mailboxes are in maildir format. Old servers and actual director servers are load balanced with an radware appdirector load balancer (the new backend servers don't need to be balanced because I'm using a director farm) In the old platform I have scenario number 2 described at http://wiki2.dovecot.org/NFS, but in the new ones I have a director proxy directing all connections from each user to the same server (I don't specify any server for the user, director selects it according to the hash algorithm it has). Some doubts I have for the recommended in that url: * mmap_disable: both single and multi server configurations have mmap_disable=yes but in index file section says that you need it if you have your index files stored in nfs. I have it stored locally. Do I need mmap_disable=yes? What it's the best? * dotlock_use_excl: it is set to no in both configurations, but the comment says that it is needed only in nfsv2. Since I have nfs3, I have it set it to yes. * mail_nfs_storage: In single server is set to no, but in multi server it set to yes. Since I have a director in front of my backend server, what is the recommended? With this configuration, when I have a few connections (about 300-400 imap connections) everything is working fine, but when I disconnect the old servers and direct all my users' connections to the new servers I have lot of errors. server loads increments to over 300 points, with a very high io wait. With atop, I could see that of my 6 cores, I have one with almost 100% waiting for i/o and the other with almost 100% idle, but load of the server is very, very high. With the old servers, I have performance problems, access to mail is slow, but it works. But with the new ones it doesn't work at all. Any idea? -- Angel L.

[Dovecot] public namespace
by Daniel Fischer 21 Jun '12

21 Jun '12

Hello, dovecot -n # 2.0.18: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-2-amd64 x86_64 Debian wheezy/sid mail_gid = 5000 mail_location = maildir:~:INDEX=/var/mail/indexes/%d/%n mail_privileged_group = vmail mail_uid = 5000 namespace { hidden = no inbox = yes list = yes location = prefix = separator = / subscriptions = yes type = private } namespace { list = children location = maildir:/var/mail/vhosts/%d/public:INDEX=/var/mail/indexes/%d/%n/public prefix = Public/ separator = / subscriptions = no type = public } i´m a little bit confused but I hope I find help here. The user mailboxes work perfectly just the public mailbox is a little bit tricky I expect that all public maildirs be placed under /var/mail/vhosts/%d/public. They are created by defining a public namespace, under which all the shared mailboxes are. For those special users, I have set the maillocation via passwd file to /%d/public/%n, all other users have /%d/%n. So we have following folder structure \public \public\.info \public\.lager \public\.buchhaltung And so on Thats works fine, but with subfolder start the problems. When the info-user loggs on and creates a subfolder under his INBOX(called hust2) then no other people can see this. Otherside, if a normal user creates a folder in public folder info(called hust), the info user can´ t see this one. If I look to filesystem, the reason is clear: %d/public/.info# ls -la insgesamt 32 drwx--S---+ 2 vmail vmail 6 Jun 19 11:50 cur -rwxrwx---+ 1 vmail vmail 51 Jun 21 09:50 dovecot-uidlist -rw-rw----+ 1 vmail vmail 8 Jun 19 11:51 dovecot-uidvalidity -r--r-----+ 1 vmail vmail 0 Jun 19 11:50 dovecot-uidvalidity.4fe04b06 drwx--S---+ 5 vmail vmail 78 Jun 19 11:54 .INBOX.hust2 drwx--S---+ 2 vmail vmail 6 Jun 19 11:50 new -rw-rw----+ 1 vmail vmail 18 Jun 19 11:51 subscriptions drwx--S---+ 2 vmail vmail 6 Jun 19 11:50 tmp drwx--S---+ 5 vmail vmail 78 Jun 21 09:51 .Trash %d/public# ls -la insgesamt 16 -rw-rw----+ 1 vmail vmail 8 Jun 19 11:51 dovecot-uidvalidity -r--r-----+ 1 vmail vmail 0 Jun 19 11:51 dovecot-uidvalidity.4fe04b36 drwx--S---+ 7 vmail vmail 4096 Jun 21 09:50 .info drwx--S---+ 5 vmail vmail 78 Jun 21 09:51 .info.hust A look to the info mailbox makes it clear: info@BLABLA \INBOX \hust2 >create by info user in his mailbox \Trash \Public \info >his own public share \hust >create by other user in public folder What I need is: %d/public/lager/cur %d/public/lager/new %d/public/lager/tmp %d/public/lager/.foo %d/public/lager/.foo.bar %d/public/ info /cur %d/public/ info /new %d/public/ info /tmp %d/public/info/.hust %d/public/info/.hust.deeperhust %d/public/info/.hust2 All public maildirs under /%d/public/%n Must I create a namespace for all public maildirs?: namespace { location = maildir:/var/mail/vhosts/%d/public/info } namespace { location = maildir:/var/mail/vhosts/%d/public/lager } I can´ t figure out on my own, please give me an explanation. Thanks for soon comment. Daniel

[Dovecot] Dovecot not liking AD config from wiki??
by Kaya Saman 21 Jun '12

21 Jun '12

I think the issue seems to be the mechanism between Dovecot and AD, so basically PAM..... I adapted my pam.d file to this: # auth auth sufficient pam_krb5.so no_warn try_first_pass debug #auth sufficient pam_ssh.so no_warn try_first_pass auth required pam_unix.so no_warn try_first_pass # account #account required pam_nologin.so #account required pam_unix.so account required pam_krb5.so in the hope that this config would work: userdb { driver = static args = uid=501 gid=501 home=/mail/%u driver = static # args = uid=500 gid=500 home=/ZPOOL_1/%u # allow_all_users=yes } passdb { driver = pam } However I am still having issues :-( Regards, Kaya

[Dovecot] Problem with Dovecot 2.0/2.1 and MySQL 5.1
by Mark Schmale 20 Jun '12

20 Jun '12

Hi everyone, since some time I got problems with dovecot & mysql. I got the problem with version 2.0.x and upgraded to 2.1.7 to check if its gone. But its not :( The logs just tell me this: dovecot: auth: Error: auth worker: Aborted request: Worker process died unexpectedly If I change to a sqlite setup, everything works fine. Here are some informations. I hope someone can tell me whats wrong with my system/setup. I really dont think that this is a bug because someone else should have hit that before me. doveconf - n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.2-hardened-r1 x86_64 Gentoo Base System release 2.1 auth_verbose = yes mail_location = maildir:~/%d/mail/%n 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 namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail user = vmail } } ssl_cert = </etc/ssl/dovecot/server.pem ssl_key = </etc/ssl/dovecot/server.key userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol lda { mail_plugins = sieve } contents of dovecot-sql.conf: default_pass_scheme = PLAIN-MD5 driver = mysql connect = host=localhost dbname=config user=user password=pass password_query = SELECT CONCAT( u.username, '@', d.name ) AS user, password FROM mail_user AS u LEFT JOIN mail_domains AS d ON u.domain = d.id WHERE u.username = '%n' AND d.name = '%d' user_query = SELECT home, uid, gid FROM mail_user AS u LEFT JOIN mail_domains AS d ON u.domain = d.id WHERE u.username = '%n' AND d.name = '%d' // linebreaks added by mailclient for readability bt full with gdb: [Thread debx7fb891e85977 "216be49381eb03d180103cdf6eb90483" fields_count = 2 name = 0x0 #1 sql_query_callback (result=0x7fb891e82f60, sql_request=0x7fb891e82c08) at passdb-sql.c:87 auth_request = 0x7fb891e82a80 _module = <optimized out> module = <optimized out> passdb_result = PASSDB_RESULT_INTERNAL_FAILURE password = 0x0 scheme = <optimized out> ret = <optimized out> __FUNCTION__ = "sql_query_callback" #2 0x00007fb891c3c940 in driver_sqlpool_query_callback (result=0x7fb891e82f60, request=0x7fb891e82e50) at driver-sqlpool.c:635 db = 0x7fb891e66540 conn = 0x0 conndb = 0x7fb891e66910 #3 0x00007fb891c3dbe0 in driver_mysql_query (db=<optimized out>, query=<optimized out>, callback=0x7fb891c3c8c0 <driver_sqlpool_query_callback>, context=0x7fb891e82e50) at driver-mysql.c:296 result = 0x7fb891e82f60 #4 0x00007fb891c3cc41 in driver_sqlpool_query (_db=0x7fb891e66540, query=0x7fb891e561c8 "SELECT CONCAT( u.username, '@', d.name ) AS user, password FROM mail_user AS u LEFT JOIN mail_domains AS d ON u.domain = d.id WHERE u.username = 'masch' AND d.name = 'masch.it'", callback=0x7fb891c31960 <sql_query_callback>, context=0x7fb891e82c08) at driver-sqlpool.c:657 db = 0x7fb891e66540 request = 0x7fb891e82e50 conn = 0x7fb891e667c0 #5 0x00007fb891c23b49 in auth_worker_handle_passv (args=0x7fb891e560b8, id=1, client=<optimized out>) at auth-worker-client.c:200 auth_request = 0x7fb891e82a80 passdb = <optimized out> password = 0x7fb891e55ff2 "somepassword" passdb_id = 1 #6 auth_worker_handle_line (line=<optimized out>, client=<optimized out>) at auth-worker-client.c:559 args = out>0x7fb891e560a8 id = 1 ret = false #7 auth_worker_input (client=0x7fb891e80650) at auth-worker-client.c:647 _data_stack_cur_id = 3 line = <optimized out> ret = true #8 0x00007fb89179f4b6 in io_loop_call_io (io=0x7fb891e80970) at ioloop.c:379 ioloop = 0x7fb891e5e390 t_id = 2 #9 0x00007fb8917a043f in io_loop_handler_run (ioloop=<optimized out>) at ioloop-epoll.c:213 ctx = 0x7fb891e69100 events = <optimized out> event = 0x7fb891e69170 list = 0x7fb891e809c0 io = <optimized out> tv = {tv_sec = 59, tv_usec = 999508} msecs = <optimized out> ret = 1 i = <optimized out> j = <optimized out> call = <optimized out> #10 0x00007fb89179ed50 in io_loop_run (ioloop=0x7fb891e5e390) at ioloop.c:398 No locals. #11 0x00007fb891786a87 in master_service_run (service=0x7fb891e5e240, callback=<optimized out>) at master-service.c:544 No locals. #12 0x00007fb891c289a3 in main (argc=2, argv=0x7fb891e5e080) at main.c:373 c = <optimized out> best regards, Mark Schmale
