[Dovecot] quota fs: Support for hardlimit quotas (where softquota is unset)
by Jan Friesse 17 Jul '12

17 Jul '12

Hi, included is patch which adds support for calculating fs quota from hardlimit where softlimit is unset. I'm usually not setting softlimit on my server causing dovecot work incorrectly (not reporting quota at all). Regards, Jan Friesse

[Dovecot] Feature request
by Malloc Kilobyte 17 Jul '12

17 Jul '12

Hi, I am implementig Dovecot as a part of my new e-mail server, which is aimed to be replacement for proprietary software I've been using sofar. Appreciating all Dovecot rich features, I lack just one. And this is the ability to customize the "quota exceeded, message rejected" message. I know I can set it's default content using quota_exceeded_message parameter, but i would also like to have ability to set: - to whom the message is sent. Some mail systems send copy not only to the sender, but also to the recipient. It makes sense in case rejected message has big size. - it's subject - if the rejected message is being attached ( with or without it's own attachments ) or not Moreover, I think it would make sense if the "rejected messege" contained information about size of rejected message and current mailbox space usage. Please, consider this in future development. with regards and respect to the tremendousness of Dovecot, -- malloc4k

[Dovecot] LDAP.conf filter issue
by Tony Hlabse 17 Jul '12

17 Jul '12

All, We are trying to use the user_filter options to limit authentication to a single user group. The cusotmer has security rules that they want to only have users belonging to a group to have access. Sample we have tried. auth_bind = yes auth_bind_userdn = EXAMPLE\%n base = / hosts = example.test.com ldap_version = 3 user_filter = (&(sAMAccountName=)(memberOf=CN=LR3BCC-DL,OU=Autonomy,OU=Exchange,OU=Enterprise Administration,DC=example,DC=test,DC=com)) Thanks Tony

[Dovecot] doveadm director status username != doveadm director status username@mailserver
by Joseba Torre 17 Jul '12

17 Jul '12

Hi, I've almost finished my new director based setup, but in the first test I discovered that imap and lmtp connections were not always being proxied to the same server. After some research now I think that the main problem is that in imap connections users connect as 'username' while lmtp connections are as 'username@mailserver'. In my current setup I receive mail via SMTP in my director servers (which are loadbalanced by a CISCO machine), and then they send them to dovecot running on localhost. I've tried to get rid of the @mailserver in postfix in a generic way with no success. Is there any way to redirect connections based only in the local part of the address? Or there is a way to get rid of the @mailserver in the postfix -> lmtp connection? Both doveadm config -n and postconf -n are attached. Thanks. $ doveadm config -n # 2.1.8: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-220.17.1.el6.x86_64 x86_64 Red Hat Enterprise Linux Server release 6.2 (Santiago) auth_debug = yes auth_master_user_separator = * auth_verbose = yes director_mail_servers = buzones2.ehu.es buzones3.ehu.es director_servers = director1.ehu.es director2.ehu.es doveadm_proxy_port = 4444 lmtp_proxy = yes mail_debug = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave passdb { args = proxy=y nopassword=y starttls=any-cert driver = static } protocols = imap pop3 lmtp sieve service auth { unix_listener auth-userdb { user = dovecot } } service director { fifo_listener login/proxy-notify { mode = 0666 } inet_listener { port = 3333 } unix_listener director-userdb { mode = 0600 } unix_listener login/director { mode = 0666 } } service doveadm { inet_listener { port = 4444 } } service imap-login { executable = imap-login director } service lmtp { inet_listener ltmp { address = director2.ehu.es 127.0.0.1 port = 24 } unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } service managesieve-login { executable = managesieve-login director vsz_limit = 128 M } service pop3-login { executable = pop3-login director } ssl_cert = </etc/ssl/private/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem syslog_facility = local1 userdb { args = allow_allusers=yes driver = static } protocol lmtp { auth_socket_path = director-userdb mail_plugins = " sieve" syslog_facility = local2 } protocol doveadm { auth_socket_path = director-userdb } $ postconf -n alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases canonical_maps = hash:/etc/postfix/canonical command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix debug_peer_level = 2 html_directory = no inet_interfaces = all inet_protocols = all local_destination_concurrency_limit = 10 local_recipient_maps = ldap:/etc/postfix/ldap-local-recipients.cf proxy:unix:passwd.byname $alias_maps mail_owner = postfix mailbox_transport = lmtp:inet:localhost:24 mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man message_size_limit = 15000000 mydestination = ehu.es, mailsever.ehu.es, othermailserver.ehu.es mydomain = ehu.es myhostname = director1.ehu.es mynetworks_style = host myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES relayhost = [smtp.ehu.es] sample_directory = /usr/share/doc/postfix-2.6.6/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop unknown_local_recipient_reject_code = 550

We don't use passdb in the directors because incoming mails have already been checked by postfix, and the final mail server need to check our ldap server for other values, so we check there.

[Dovecot] imapc: Restrict the number of connections
by René Neumann 17 Jul '12

17 Jul '12

Hi, I have managed to get an imapc connection to another server and bind its contents to only one account (via global ACL). The namespace itself is created as public, though it does not seem to make a difference for this use case (i.e., it does not matter, whether its type is 'public', 'shared', or 'private'). namespace { hidden = no list = children location = imapc: prefix = Gemeinsam. separator = . subscriptions = no type = public } One problem remains: Though there is only one account that is allowed to use this imapc-connection, each imap-process opens a connection to the imapc'd server. Is this caused directly by the imapc_*-definitions in the config? Or is there a way of restricting this to only the account which actually uses it. Used dovecot version: 2.1.8 Thanks, René

Dear Timo, Do you intend to introduce bcrypt into the built in password schemes? In lew of all these hacks lately many larger companies appear moving this way, we are looking at it too, but dovecot will then be the weakest link in the database security. So, are you planning on this and if so what sort of timeframe / version would you expect it to be in beta ? Nik

[Dovecot] incremental backups of maildir via rsync

-----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?

[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

[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

[Dovecot] imap-login: Panic: epoll_ctl(add, 6) failed: Invalid argument

13 Jul '12

Hello, More problems (it seems that we won't be able to put our new servers in production). The problem now is that when we reach 1000 dovecot processes we have errors like: Jul 9 12:10:22 myotis31 dovecot: imap-login: Panic: epoll_ctl(add, 6) failed: Invalid argument Jul 9 12:10:22 myotis31 dovecot: imap-login: Fatal: master: service(imap-login): child 32251 killed with signal 6 (core dumps disabled) and server doesn't accept any new connection. Our servers are running in ubuntu 12.04 with kernel 3.2.0-24-generic kernel. I have found a similar problem at https://bugzilla.redhat.com/show_bug.cgi?id=681578 but it is for redhat kernel of series 2.6. Could be the same problem? Any pointer to this problem for ubuntu kernels? Or for generic 3.0 kernels? Any idea? -- Angel L.

[Dovecot] mail_log plugin logs UTF-8 mailbox name
by Ewald Dieterich 11 Jul '12

11 Jul '12

A small bug in the mail_log plugin: When I copy a mail from the inbox to a mailbox with special characters, the mailbox name is logged in UTF-8: [...] copy from INBOX: box=INBOX.Euro €, [...] I guess the name should be in mUTF-7, like it is done when I copy the other way round: [...] copy from Euro &IKw-: box=INBOX, [...]

Hi all, I'm using dsync for backups. I recently upgraded to 2.1.7 due to issues with dsync mirror/backups. 2.1.7 fixed the issue with the guid conflict, but now I'm seeing this error on a couple of mailboxes: Error: proxy client timed out (waiting for output stream to flush, 0 bytes left) If there are 0 bytes left, why is it trying to flush? I'm using this command to backup the mailbox: dsync -vo mail_home=/home/users/user%domain.com backup ssh vmail(a)10.1.2.2 dsync -o mail_home=/home/.incoming_mail_migrations/users/user%adomain.com Any ideas? ...Jeff

First, this sub discussion in this thread has been dealing strictly with mechanical storage, and that was intentional. Now you've injected solid state storage, and in the process you first disagreed with my statement, then agreed with it. Apparently you didn't realize you did so. Would you please clarify what I stated that is "simply not true"? You comment WRT SSD doesn't prove anything I said to be untrue. Quite the contrary, you reinforced my statements. -- Stan

[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] configuring imap_stats
by Reinhard Vicinus 09 Jul '12

Hi, i'm trying to configure imap_stats like it's documented in the wiki: http://wiki2.dovecot.org/Statistics. But as soon as i activate the imap_stats plugin i get the following error message trying to login via imap: dovecot: imap: Error: Can't load plugin imap_stats_plugin: Plugin stats must be loaded also (you must set: mail_plugins=$mail_plugins stats) But the stats plugin is configured as you can see in the attached configurations. Also i can get statistics without the imap_stats enabled, but as far as i know only of the pop3 users. Kind regards Reinhard

[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 . Fixed looking up parent mailbox name with different namespace vs. layout separators. . imapc: Don't list mailboxes that don't match list patterns. . layout=fs: Fixed listing mailboxes with prefix=INBOX/ . LIST with mailbox {} settings incorrectly set subscribed-flags. Here is my dovecot -n output: # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.5 auth_default_realm = example.net auth_verbose = yes default_process_limit = 256 default_vsz_limit = 512 M dict { expire = mysql:/etc/dovecot/dovecot-dict-sql.conf quota = mysql:/etc/dovecot/dovecot-dict-sql.conf } disable_plaintext_auth = no first_valid_gid = 8 first_valid_uid = 8 last_valid_gid = 8 last_valid_uid = 8 listen = * login_greeting = howdy, ready. mail_location = mdbox:~/mdbox:INDEX=/srv/dovecot_indexes/%d/%1n/%n mail_plugins = expire quota zlib stats maildir_very_dirty_syncs = yes namespace { inbox = yes location = prefix = separator = . } namespace { alias_for = hidden = yes inbox = no list = no location = prefix = INBOX. separator = . } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { antispam_allow_append_to_spam = yes antispam_backend = pipe antispam_debug_target = syslog antispam_pipe_program = /usr/local/bin/train_spam antispam_pipe_program_args = -d;10.0.1.109 antispam_pipe_program_notspam_arg = ham antispam_pipe_program_spam_arg = spam antispam_pipe_tmpdir = /var/tmp antispam_signature = X-Spam-Flag antispam_signature_missing = error antispam_spam_pattern_ignorecase = SPAM antispam_trash_pattern = trash;Trash;Deleted * expire = Trash expire2 = Trash/* expire3 = Spam expire_dict = proxy::expire quota = dict:Your mail quota::proxy::quota quota_rule = *:bytes=100663296 quota_rule2 = Trash:bytes=+20%% quota_rule3 = Spam:bytes=+10%% quota_rule4 = INBOX.Trash:bytes=+20%% quota_rule5 = INBOX.Spam:bytes=+10%% quota_rule6 = INBOX.restored_from_backups:bytes=+500%% sieve = ~/.dovecot.sieve sieve_after = /var/lib/dovecot/sieve/after.sieve sieve_before = /var/lib/dovecot/sieve/default.sieve sieve_dir = ~/sieve stats_refresh = 30 secs stats_track_cmds = yes zlib_save = gz zlib_save_level = 6 } postmaster_address = postmaster(a)example.net protocols = " imap pop3" service anvil { unix_listener anvil { group = dovecot mode = 0660 user = root } } service auth { unix_listener auth-userdb { group = mail mode = 0600 user = mail } } service dict { unix_listener dict { group = mail mode = 0600 user = mail } } service imap-login { process_min_avail = 10 service_count = 0 vsz_limit = 512 M } service imap-postlogin { executable = script-login /usr/local/sbin/postlogin_imap } service imap { executable = imap imap-postlogin process_limit = 2048 } service pop3-login { process_min_avail = 10 service_count = 0 vsz_limit = 512 M } service pop3-postlogin { executable = script-login /usr/local/sbin/postlogin_pop } service pop3 { executable = pop3 pop3-postlogin } service stats { fifo_listener stats-mail { mode = 0600 user = mail } } ssl_cert = </etc/certs/wildcard/cert.pem ssl_cipher_list = HIGH:-ADH:-aNULL ssl_key = </etc/certs/wildcard/key.pem userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } verbose_proctitle = yes protocol lda { mail_plugins = expire quota zlib stats sieve plugin { quota_exceeded_message = Sorry, your message cannot be delivered to that person because their mailbox is full.

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? Regards Hans de Groot

[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
by Peter Fraser 05 Jul '12

05 Jul '12

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

[Dovecot] userdb errors after upgrading to 2.1
by André Rodier 03 Jul '12

03 Jul '12

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. Can you point me in the right direction to fix this, please? Kind regards, André Rodier

[Dovecot] Wrong headers in dovecot-crlf

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