Hi I allready have set 256 on max_user_instances , and in the log i keep seeing Mar 28 10:08:44 mail dovecot: imap(some.username): Warning: Inotify instance limit for user 98 (UID vmail) exceeded, disabling. Increase /proc/sys/fs/inotify/max_user_instances All users use thunderbird 3.1.9 , and from time to time this show in log , with a random user.

[Dovecot] v1.2.12 and debug
by Walt Shekrota 30 Mar '11

30 Mar '11

Is there some kind of extended debug that might show why my maildir is not foundat login? It has worked off and on, once briefly today then no more. I'm going around twiddling knobs guessing at this point which is foolish. I need some real bread crumbs to indicate what is going wrong. I've tried all kinds of .conf file ... example file etc. I figured using the least number of settings should get me somewhere but I still have no luck. I'd love to just give up and load that PPA for 2.x but I have no idea what package to install in debian. (I have the PPA update) Thanks. -Walt

[Dovecot] dovecot.conf
by Walt Shekrota 30 Mar '11

30 Mar '11

In 1.2.12 or there abouts how do changes in the dovecot.conf happen? After doing the sig HUP I have noted there is generally a delay in the recognition of items in my .conf. An example I had logging set off, turned it on and it was several restarts before I again saw logging? This delay is driving me nuts in trying to figure out what needs to change. Thanks. -Walt

[Dovecot] migrating to dovecot
by Alexandre Chapellon 30 Mar '11

30 Mar '11

Hello, I am trying to setup a migration scenario from an proprietary solution to dovecot IMAP/POP3. Whereas am only at the strating point, things appear quite complicated because of the following reasons: - The proprietary solution uses special/own/proprietary mailbox format (wich is more like maildir but is not maildir) - I don't have direct access to the filesystem where the mails are stored. The best I could do would be a snapshots of the filesystem - I have about 1,5TB of mail data. - Having users to be forced to empty their mailbox before migration or re-download their whole mailbox after migration would be something hard for me to present as a correct option. Am looking for advices that would avoid me loosing time searching in bad directions. Or even point me to a miraculous tool thatdoes all magic while i have a beer :) Best regards. -- horoa: la voie est libre

To elaborate, if there is a database associated with this setup it is really fubar. note: tail of dovecot -n lda: postmaster_address: postmaster mail_plugins: sieve quota_full_tempfail: yes deliver_log_format: msgid=%m: %$ rejection_reason: Your message to <%t> was automatically rejected:%n%r auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 504 socket: type: listen client: path: /var/spool/postfix/private/dovecot-auth mode: 432 user: postfix group: postfix plugin: sieve: ~/.dovecot.sieve sieve_dir: ~/sieve This in no way represents the settings in my dovecot.conf. It seems to have rembered old .conf settings and mixed them. At no time was mode 504 set or even 432. What am I doing wrong? Thanks. -Walt I'm also toying with the idea of loading 2.x if I can figure out the PPA stuff.

[Dovecot] file permissions
by Walt Shekrota 29 Mar '11

29 Mar '11

Dovecot 1.2.12 maildir format using :LAYOUT=fs (my Mail dir came from KDE) I can't remember the permissions of the /Mail/ directory because I haven't been concerned with it too much until now. I think they were user:user or user:mail. Now a new mail ends up 600 root:mail. (in alternate directories) When I start my mutt client to the imap server it gets an error for any folder containing a root:mail new mail file. I think the root ownership is a procmail side effect? If I chmod 760 Mail/folder/* (then the new emails show in dovecot without the access error) It appears mail comes to the INBOX fine just not individual folders On the initial access, dovecot gets a "missing +r perm" or "+x" in the log. 1: What permission structure should permeate my Mail dir? 2: What might affect the incoming mail file getting wrong permissions/ownership? I'm thinking the later may be a procmail issue unless it is related to initial incorrect permissions? Thanks for any insight. -Walt

[Dovecot] Trouble with password scheme module
by Ian R. Justman 29 Mar '11

29 Mar '11

Hi, all. About two and a half years ago, I wrote a hack to add an additional MD5-based password scheme to Dovecot, but I wrote it as a hack to src/auth/password_scheme.c since it was relatively easy to do, and I needed to get a machine running since the machine I was replacing, a Sun Ultra 5 running Post.Office, had dying hard drives. Now, I'm actually sitting down and adapting it as a module and am having trouble getting it to work. The code tarball itself can be picked up here: http://www.ian-justman.com/code/dovecot/password_scheme_po_smd5.tar.gz Before I continued, I made sure that a system-level account worked: # telnet <server IP> 110 Trying <server IP>... Connected to <server IP>. Escape character is '^]'. +OK Dovecot ready. user <username> +OK pass <password> +OK Logged in. quit +OK Logging out. Connection closed by foreign host. I then enabled the module, which introduces the password scheme "PO-SMD5". I have Dovecot's default scheme set to SMD5. If I get a password hash whose value has a {PO-SMD5} tag on it, the session looks like the following: # telnet <server IP> 110 Trying <server IP>... Connected to <server IP>. Escape character is '^]'. +OK Dovecot ready. user <user with PO-SMD5 password> +OK pass <user's password> -ERR Authentication failed. quit +OK Logging out Connection closed by foreign host. The following entry is deposited into the system log: Mar 28 17:44:51 <hostname> dovecot: auth: Error: sql(<username>,<server IP>): Unknown scheme PO-SMD5 However, when I try using an account covered by the system (which does work when the plugin isn't loaded in dovecot.conf), the session looks like the following: mikuru# telnet <server IP> 110 Trying <server IP>... Connected to <server IP>. Escape character is '^]'. +OK Dovecot ready. user <user with system password> +OK pass <user's password> Connection closed by foreign host. The following entry is deposited into the system log: Mar 28 17:45:13 <hostname> dovecot: pop3: Error: dlopen(/usr/local/lib/dovecot/lib_password_scheme_po_smd5.so) failed: /usr/local/lib/dovecot/lib_password_scheme_po_smd5.so: Undefined symbol "password_scheme_unregister" Otherwise, the patch I developed under 1.x applies cleanly to 2.0.x's password_scheme.c and works perfectly as a builtin. This work was done under FreeBSD 8.1-RELEASE amd64. Any ideas? --Ian. -- Ian R. Justman UNIX hacker. Anime fan. Any questions? ianj (at) ian-justman.com

[Dovecot] dovecot auth password mismatch
by david＠davidwbrown.name 28 Mar '11

28 Mar '11

Hello dovecot gods, after using Postfix with webmail for 8 years the new gen of email smartphones forces me to consider using IMAP. Actually, for several months I was successfully using IMAP. I believe the reason why IMAP worked previously (before migrating to the Cloud) the hosting server and the client machines were considered local by the system. Now, I have moved everything to a Cloud service. And, now attempts to use my Ubuntu Evolution or iPhone generates the following error condition in my logs: dovecot: auth(default): client in: AUTH 1 PLAIN service=imap lip=xxx.yyy.www.zzz rip=75.214.160.72 lport=143 rport=59107 resp=AGRhdmlkAGx1dGVmaXNr dovecot: auth(default): passwd(kilroy,75.214.160.72): lookup dovecot: auth(default): passwd(kilroy,75.214.160.72): Password mismatch dovecot: auth(default): passwd(kilroy,75.214.160.72): CRYPT(mypass) != 'x' dovecot: auth(default): new auth connection: pid=15522 dovecot: auth(default): client out: FAIL 1 user=kilroy ******************* dovecot -n ******************* 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.34.1-rscloud x86_64 Ubuntu 10.04.2 LTS log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: maildir:~/Maildir mbox_write_locks: fcntl dotlock auth default: realms: myname.name, hisname.name, hername.name default_realm: myrealm.com username_format: %n verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd userdb: driver: passwd

[Dovecot] Errors logged from 2.0.11
by Andreas Kossack 28 Mar '11

28 Mar '11

Hi all, we use dovecot 2.0.11 with local (LDAP based) users and see (occasionally) error messages like "Mar 15 09:29:26 MailServ local3:err|error dovecot: imap(xxxx): Error: creat(/dovecot.mailbox.log) failed: Permission denied (euid=1985(xxxx) egid=219(yyyy) stat() failed: No such file or directory, euid is not dir owner) but all (filesystem) permissions are correct and the user doesn't report any errors. All works as expected. What can be the reason for such messages? -- Mit freundlichen Grüßen A.

[Dovecot] IMAP move extension support
by Nikolay Shopik 28 Mar '11

28 Mar '11

Hi Timo, Any chance we could get IMAP move extension support in Dovecot? http://tools.ietf.org/html/draft-krecicki-imap-move-01 This is now landed in Thunderbird trunk, so it will be great to have server to test and use with :). Thanks

[Dovecot] Regression in settings-parser.c (dovecot 2.0.11)
by Michal Hlavinka 28 Mar '11

28 Mar '11

Hi, one Fedora user sees regression in dovecot 2.0.11 (compared to prev. 2.0.9). There was change recently: http://hg.dovecot.org/dovecot-2.0/diff/bc77e80947c0/src/lib-settings/settin… which adds call to settings_find_key_nth(...., &parent_def,...). This function can set parent_def to NULL, but there is no check for this situation in the code. So on next line if (parent_def->type !=... dovecot crashes. We've tested simple fix: if (parent_def==NULL) return FALSE; and everything was working again. Michal Backtrace of the crash: Program received signal SIGSEGV, Segmentation fault. settings_find_key_nth (ctx=0x99e4050, key=0x99c4330 "plugin//etc", n=0xbff9bdac, def_r=0xbff9bda8, link_r=0xbff9bda4) at settings-parser.c:696 696 if (parent_def->type != SET_STRLIST) (gdb) p parent_def $1 = (const struct setting_define *) 0x0 (gdb) bt #0 settings_find_key_nth (ctx=0x99e4050, key=0x99c4330 "plugin//etc", n=0xbff9bdac, def_r=0xbff9bda8, link_r=0xbff9bda4) at settings-parser.c:696 #1 0x004f9ce5 in settings_find_key_nth (ctx=0x99e4050, key=0x99c4318 "plugin//etc/dovecot", n=0xbff9be1c, def_r=0xbff9be18, link_r=0xbff9be14) at settings-parser.c:693 #2 0x004f9ce5 in settings_find_key_nth (ctx=0x99e4050, key=0x99c42f8 "plugin//etc/dovecot/users", n=0xbff9beb4, def_r=0xbff9bebc, link_r=0xbff9beb8) at settings-parser.c:693 #3 0x004f94fd in settings_parse_keyvalue (ctx=0x99e4050, key=0x99c42f8 "plugin//etc/dovecot/users", value=0x99c42f2 "yes") at settings-parser.c:760 #4 0x004fa270 in settings_parse_line (ctx=0x99e4050, line=0x99c42d8 "plugin//etc/dovecot/users=yes") at settings-parser.c:862 #5 0x00dededa in set_line (ctx=0x99cd468, input=0xbff9c100, user_r=0xbff9c04c, error_r=0xbff9c0fc) at mail-storage-service.c:134 #6 user_reply_handle (ctx=0x99cd468, input=0xbff9c100, user_r=0xbff9c04c, error_r=0xbff9c0fc) at mail-storage-service.c:227 #7 mail_storage_service_lookup (ctx=0x99cd468, input=0xbff9c100, user_r=0xbff9c04c, error_r=0xbff9c0fc) at mail-storage-service.c:843 #8 0x00deeaae in mail_storage_service_lookup_next (ctx=0x99cd468, input=0xbff9c100, user_r=0xbff9c0ac, mail_user_r=0xbff9c0a8, error_r=0xbff9c0fc) at mail-storage-service.c:968 #9 0x0805f2e7 in client_create_from_input (input=<value optimized out>, ---Type <return> to continue, or q <return> to quit--- login_client=0x99ce810, fd_in=11, fd_out=11, input_buf=0xbff9c0e0, error_r=0xbff9c0fc) at main.c:202 #10 0x0805f5dd in login_client_connected (client=0x99ce810, username=0x99c409b "sjoerd", extra_fields=0x99c4110) at main.c:267 #11 0x0051606f in master_login_auth_finish (client=0x99ce810, auth_args=<value optimized out>) at master-login.c:206 #12 0x005163c2 in master_login_auth_callback (auth_args=0x99c410c, errormsg=0x0, context=0x99ce810) at master-login.c:374 #13 0x00516d3e in master_login_auth_input_user (auth=0x99cdcd8) at master-login-auth.c:239 #14 master_login_auth_input (auth=0x99cdcd8) at master-login-auth.c:359 #15 0x0052cc72 in io_loop_call_io (io=0x99cea10) at ioloop.c:384 #16 0x0052ded3 in io_loop_handler_run (ioloop=0x99cc390) at ioloop-epoll.c:213 #17 0x0052cbf0 in io_loop_run (ioloop=0x99cc390) at ioloop.c:405 #18 0x005181fb in master_service_run (service=0x99cc2e0, callback=0x805f100 <client_connected>) at master-service.c:478 #19 0x0805fb0d in main (argc=1, argv=0xbff9c4c4) at main.c:375

[Dovecot] FTS Compound Search
by duonut 28 Mar '11

28 Mar '11

Hi I use roundcube as the webmail fronted to a dovecot server. It currently has squat enabled. When round cube performs a search, it does a compound search even if only one field is selected. >From another thread i read, dovecot in the v1 period did not support compound searches for squat. Does the latest version of V2 support compound searches with fts squat? If not, does fts with solr support compound searches? -- View this message in context: http://old.nabble.com/FTS-Compound-Search-tp31241908p31241908.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Dovecot 2.0.9: Thunderbird 3.1.9: Very slow while open sent folder with many (4k>) mails
by Denny Schierz 27 Mar '11

27 Mar '11

hi, one customer told us, that he has performance problem in his Thunderbird 3.1.9, while open his sent folder, which has round about 4000 mails in it, and 20k in his Inbox. For example TB, tries to sync the sent-folder list (over SSL) from the sent folder for now over 15min. In the log, I can't see any strange things, so for me, Dovecot works ok. Maybe, I should use better cache options? Now he tries to move many messages to separate folders, but thats also a bit slow. So, is it a TB problem, with so many messages?

[Dovecot] How can I view these email files?
by Phill Edwards 27 Mar '11

27 Mar '11

I messed up my email today through a combination of stuff-ups with procmail and dovecot. The result was that I ended up delivering some email messages to the root Maildir folder instead of the sub-folders. The files are in the correct format but have names like msg.3BXE, msg.2BXE etc. Of course these don't show up in my IMAP client so I can't read them. Does anyone know a way I can point some sort of email client at these to read them? Or a way to transfer them under Maildir/new so that I can read them as part of my normal inbox?

[Dovecot] Multiple versions of Dovecot installed
by Phill Edwards 26 Mar '11

26 Mar '11

I have had to rebuild my 64-bit CentOS 5 email server and after installing dovecot rpms (using yum) I seem to have multiple versions installed: dovecot-1.1.20-1_98.el5 - from ATrpms repo dovecot-1.0.7-7.el5 - from CentOS repo dovecot-sieve-0.1.18-6.1.el5 - from ATrpms repo I have tried to install just the ATrpms version but when I do "yum install dovecot" the CentOS one always gets pulled in as well. Is this normal, or does it indicate that something has gone wrong in the installation process? I'm having an issue with Dovecot sieve because it can't find a sieve plugin in /usr/lib64/dovecot/lda/. However, there is one in /usr/lib/dovecot/lda/. Do I have some sort or 32-bit/64-bit mismatch?

Hi help is preciated, PROBLEM The dovecot-ldap.conf of "proxy server A" is working when the "host" attribute is the FQDN of other server: pass_attrs = uid=user,userPassword={SSHA}password,\ =proxy_maybe=,maildrop=host,=port=143,=destuser=%u,=starttls=any-cert pass_filter = (&(objectClass=posixAccount)(uid=%u)) CASES When the "host" attribute is the "FQDN of server A" dovecot imap-login start and infinite loop which swallow all RAM, and process are showing many connections although is just 1 test user connected.

[Dovecot] mdbox, quota, ns, maildir quota?
by Brandon Lamb 26 Mar '11

26 Mar '11

Hello, I pasted my config below, hoping someone can point out something obvious. In my dovecot.log I am seeing: Warning: quota: Namespace '' is not Maildir, skipping for Maildir++ quota I am using mysql userdb_* and passing maildir:~/maildir or mdbox:~/mdbox for mail. When its maildir its fine, I had that originally then used dsync to convert to mdbox, updated mysql entry to point to mdbox:~/mdbox and now I keept getting those quota errors. It IS possible to have mixed environment still correct? Some users can be maildir and some can be mdbox since Im using the per-user userdb options? Any hints here? I would swear this was all working on a different server I had setup but Im no longer employed there so I cant peek at the config =P Thanks for any help or tips Brandon ------------------------------------------------------------------------------- root@mail1:~# dovecot -n # 2.0.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.37-2-amd64 x86_64 Debian wheezy/sid auth_cache_negative_ttl = 30 secs auth_cache_size = 4 k auth_cache_ttl = 30 secs auth_default_realm = greencrane.com auth_mechanisms = plain login auth_username_format = %Lu auth_verbose = yes auth_worker_max_count = 60 base_dir = /var/run/dovecot debug_log_path = /var/log/dovecot/debug.log default_client_limit = 1024 default_internal_user = mail default_login_user = mail deliver_log_format = %s from %f %$ dict/expire = mysql:/etc/dovecot/conf.d/dovecot-dict-expire.conf.ext disable_plaintext_auth = no first_valid_gid = 8 first_valid_uid = 8 info_log_path = /var/log/dovecot/info.log last_valid_gid = 8 last_valid_uid = 8 log_path = /var/log/dovecot/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " login_log_format = %s login_log_format_elements = (%u) (%r) mail_access_groups = mail mail_fsync = never mail_gid = 8 mail_location = maildir:~/maildir mail_log_prefix = "%Ls <%u>: " mail_max_userip_connections = 4 mail_plugins = quota expire mail_privileged_group = mail mail_uid = 8 mailbox_idle_check_interval = 1 mins maildir_very_dirty_syncs = yes passdb { args = /etc/dovecot/conf.d/dovecot-sql.conf.ext driver = sql } plugin/auth_socket_path = /var/run/dovecot/auth-master plugin/autocreate = Trash plugin/autocreate2 = Sent plugin/autocreate3 = Drafts plugin/autocreate4 = Spam plugin/autosubscribe = Trash plugin/autosubscribe2 = Sent plugin/autosubscribe3 = Drafts plugin/autosubscribe4 = Spam plugin/quota = maildir:User quota plugin/quota_warning = storage=95%% quota-warning 95 %u plugin/quota_warning2 = storage=80%% quota-warning 80 %u protocols = imap pop3 service auth { executable = /usr/local/libexec/dovecot/auth unix_listener auth-client { group = mail mode = 0666 user = mail } unix_listener auth-master { group = mail mode = 0666 user = mail } unix_listener auth-userdb { group = mail mode = 0666 user = mail } vsz_limit = 512 M } service dict { unix_listener dict { group = mail mode = 0666 } } service imap-login { chroot = login client_limit = 512 executable = /usr/local/libexec/dovecot/imap-login process_limit = 20 process_min_avail = 4 service_count = 0 user = dovecot vsz_limit = 128 M } service imap { drop_priv_before_exec = no executable = /usr/local/libexec/dovecot/imap vsz_limit = 512 M } service pop3-login { chroot = login client_limit = 512 executable = /usr/local/libexec/dovecot/pop3-login process_limit = 20 process_min_avail = 4 service_count = 0 user = dovecot vsz_limit = 128 M } service pop3 { drop_priv_before_exec = no executable = /usr/local/libexec/dovecot/pop3 vsz_limit = 512 M } service quota-warning { executable = script /etc/dovecot/quota-warning.sh user = mail } ssl_cert = </etc/dovecot/ssl/dovecot-cert.pem ssl_key = </etc/dovecot/ssl/dovecot-key.pem userdb { driver = prefetch } userdb { args = /etc/dovecot/conf.d/dovecot-sql.conf.ext driver = sql } valid_chroot_dirs = /mail verbose_proctitle = yes protocol lda { auth_socket_path = /var/run/dovecot/auth-userdb info_log_path = /var/log/dovecot/deliver.log lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes log_path = /var/log/dovecot/deliver.log mail_fsync = optimized mail_plugin_dir = /usr/local/lib/dovecot mail_plugins = quota expire trash autocreate postmaster_address = postmaster(a)greencrane.com quota_full_tempfail = yes rejection_reason = Your message to <%t> with subject of <%s> was automatically rejected:%n%r rejection_subject = Mailbox Full: %s sendmail_path = /usr/sbin/exim } protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep imap_id_log = * imap_logout_format = bytes=%i/%o imap_max_line_length = 64 k mail_max_userip_connections = 20 mail_plugin_dir = /usr/local/lib/dovecot mail_plugins = quota expire imap_quota autocreate trash } protocol pop3 { mail_max_userip_connections = 2 mail_plugin_dir = /usr/local/lib/dovecot mail_plugins = quota expire pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_enable_last = no pop3_lock_session = no pop3_logout_format = retr=%r/%b, del=%d/%m, size=%s pop3_no_flag_updates = yes pop3_reuse_xuidl = no pop3_save_uidl = yes pop3_uidl_format = %g }

by Frank Bonnet 26 Mar '11

26 Mar '11

Hello Is there a way to restrict access to Dovecot server during mailboxes convertion ? I need dovecot to be running to convert mailboxes from a format to another, but I would like to block all our LAN clients until the end of convertion. If there is no internal Dovecot mechanism I will use some firewall rule on the server. Thanks

[Dovecot] lda_mailbox_autocreate and lda_mailbox_autosubscribe
by Frank Bonnet 25 Mar '11

25 Mar '11

Hello I use real unix users on the mailhub and I would like to automate home directories creation for new users. I found lda_mailbox_autocreate and lda_mailbox_autosubscribe statements in 15-lda.conf file ( dovecot 2.0.11 ) which seem to be the right things for me :-) I use Postfix 2.8.1 with Dovecot LDA mailbox_command = /usr/local/libexec/dovecot/dovecot-lda All Mailboxes are located in /user/$USER/mail/ Does those two statements means that if a home directory does not exists it will be created at the first login of the new user ? I mean if new user "toto" has no homedir at all , dovecot will create /user/toto/mail at the very first successful connection ? Thanks a lot

[Dovecot] Issue with Dovecot v2.0 auto packages
by Stephan Bosch 25 Mar '11

25 Mar '11

Hi, Yesterday night I upgraded the automated packages built at Xi to the latest experimental Debian packages for v2.0. This unfortunately causes a problem upon upgrade. I've contacted the maintainer, so this issue should resolve itself soon. The issue manifests as follows: Setting up dovecot-imapd (2:2.0.11-0~auto+25) ... ucfr: Attempt from package dovecot-imapd to take /etc/dovecot/conf.d/20-imap.conf away from package dovecot-common ucfr: Aborting. dpkg: error processing dovecot-imapd (--configure): subprocess installed post-installation script returned error exit status 4 configured to not write apport reports The Debian maintainer split dovecot-common in various new packages and moved config files in the process. Use ucfr --purge --force dovoecot-imapd /etc/dovecot/conf.d/20-imap.conf ucfr --purge --force dovoecot-managesieved /etc/dovecot/conf.d/20-managesieve.conf ucfr --purge --force dovoecot-sieve /etc/dovecot/conf.d/90-sieve.conf to get rid of these errors as a workaround. I did this in combination with temporarily purging and removing Dovecot, but that is probably not necessary. Once you have upgraded, you will not encounter this problem again. And yes, if you are using Sieve, be sure to install the new dovecot-sieve and dovecot-managesieved packages. Regards, Stephan.

[Dovecot] Dotlock dovecot-uidlist errors / NFS / High Load
by list＠airstreamcomm.net 24 Mar '11

24 Mar '11

As of late our four node dovecot 1.2.13 cluster has been experiencing a massive number of these dotlock errors: Created dotlock file's timestamp is different than current time (1295480202 vs 1295479784): /mail/user/Maildir/dovecot-uidlist These dotlock errors correspond with very high load averages, and eventually we have to turn off all but one server to stop them from occurring. We first assumed this trend was related to the NFS storage, but we could not find a networking issue or NFS related problem to speak of. We run the mail storage on NFS which is hosted on a Centos 5.5 host, and mounted with the following options: udp,nodev,noexec,nosuid. Secondly we thought the issues were due to NTP as the time stamps vary so widely, so we rebuilt our NTP servers and found closer stratum 1 source clocks to synchronize to hoping it would alleviate the problem but the dotlock errors returned after about 12 hours. We have fcntl locking set in our configuration file, but it is our understanding from look at the source code that this file is locked with dotlock. Any help troubleshooting is appreciated.

[Dovecot] Problem with expire plugin and expunge
by Christoph Pleger 24 Mar '11

24 Mar '11

Hello, I am running dovecot 2.0.9 with expire plugin, using the sqlite backend. The following command is executed every day by cron: doveadm expunge -A mailbox Trash savedbefore 30d I started to use the expire plugin about one month ago. Since then, using "doveadm search -A mailbox Trash savedbefore <days>" with different values for <days>, I could see every day how the messages were getting older. Yesterday was the first time that the expression "savedbefore 30d" became true for the oldest messages in the Trash mailbox and these messages were actually deleted from Trash. But today, all messages that were not deleted yesterday are new to "doveadm search", that means that "doveadm search -A mailbox Trash savedbefore 0d" shows all messages from Trash, but "doveadm search -A mailbox Trash savedbefore 1d" shows no messages from Trash, though during the last month I moved messages to Trash every day.

[Dovecot] Configure Dovecot For IMAP Only?
by Carlos Mennens 23 Mar '11

23 Mar '11

I've install Dovecot 2.0.11-1 on my Linux server and all the guides and tutorials I've found on Google don't work since I'm running 2.x and it seems most guides were done with 1.x. I've opened up the configuration file /etc/dovecot/dovecot.conf & from what I can see, this is all I could come up with: protocols = imap listen = * base_dir = /var/run/dovecot login_greeting = Server ready. mail_location = maildir:~/mail I obviously want / need IMAP4 access ONLY and not POP3. I've got only 12 local Linux shell users and all authentication is done by I think PAM. My friend sent me his configuration file to see if it would work on Dovecot 2.x however I don't think it does: auth_mechanisms = plain login mail_location = maildir:~/mail passdb { driver = pam } protocols = imap service auth { unix_listener auth-client { group = postfix mode = 0660 user = postfix } user = root } ssl_cert = </etc/ssl/certs/cert.pem ssl_key = </etc/ssl/private/key.pem userdb { driver = passwd } #protocol imap { # imap_client_workarounds = delay-newmail tb-extra-mailbox-sep #} Can anyone please tell me what I need to add to get this very basic IMAP server up and running?

[Dovecot] Mail Sync
by Scott Hughes 23 Mar '11

23 Mar '11

I am trying to sync my mail on two different servers as testing for converting our business over to a server using dovecot. I am currently running dovecot version 2.0.11 While trying to sync the messages using Thunderbird and a program named imapsync, I run into an error stating that the dovecot server does not know how to handle messages with the FORWARD flag set. Is the FORWARD flag some type of non-standard flag or is there something I need to do in dovecot to allow for this flag? Thanks

[Dovecot] Bug: Creating mbox folders
by Kelly Stephens 23 Mar '11

23 Mar '11

Hey, I had trouble this morning creating a folder to contain sub-folders. I am using the mbox format. Turns out that the .imap directory in the new folder (directory) was not being created. Anytime I tried to view a sub-folder (using Thunderbird) dovecot would dump. Once I manually created the .imap directory, it works fine. dovecot --version -> 2.0.9 dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.35.11-83.fc14.i686 i686 Fedora release 14 (Laughlin) listen = * mbox_write_locks = fcntl passdb { driver = pam } protocols = imap ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } The maillog dump...

[Dovecot] different users with different quota
by Jim Knuth 23 Mar '11

23 Mar '11

Hello, How can one assign different users different Quota? So properly? quota_rule1 = userONE:storage=1G quota_rule2 = Trash:storage=100M quota_rule3 = SPAM:ignore quota_rule4 = userTWO:storage=5M quota_rule5 = Trash:storage=50M quota_rule6 = SPAM:ignore and so on ... Right or how? -- Mit freundlichen Grüßen, Jim Knuth P.S.: Bitte senden Sie KEINE HTML-Mails! Zufallszitat: Die Geschichte wird freundlich mit mir umgehen, denn ich habe vor, sie zu schreiben.

[Dovecot] FETCH got too little data (+ wrong W value) with 1 byte offset
by Vincent Artzner 23 Mar '11

23 Mar '11

Hi there, I juste set up dovecot as local imap server last week, with maildir format. Things went fine with two "low volume" accounts, until I added another one. Then I see two different things with connected clients: 1/ Quite oftent well formed messages that appear... and disappear quite immediately. On the server, the messages concerned by 2/ seem to be there, I can open the files and it looks ok (header, content). The only error log I get is this: 2011-03-18 14:43:14 IMAP(info): Info: Disconnected: FETCH failed bytes=109363/174063195 2011-03-18 14:43:14 imap-login: Info: Login: user=<info>, method=PLAIN, rip=192.168.0.191, lip=192.168.0.10, TLS 2011-03-18 14:43:15 IMAP(info): Error: FETCH [] for mailbox Envois UID 11572 got too little data: 63454 vs 63455 2011-03-18 14:43:15 IMAP(info): Error: Maildir filename has wrong W value: /home/info/Maildir/.Envois/cur/1300450349.M120256P3108.Serveurlinux,S=460764,W=460768:2,S 2011-03-18 14:43:15 IMAP(info): Error: Corrupted index cache file /home/info/Maildir/.Envois/dovecot.index.cache: Broken virtual size for mail UID 11572 Please note the size: 63454 vs 63455: it's always like that: one byte difference.

I also reproduced it with opera mail client. I tried to rename/delete dovecot.index.cache files as I have read about it, but doesn't changed anything. The incoming mails are provided to dovecot by procmail, so I think dovecot is responsible for settings the S, W params in the filenames. No other process should alter the messages (i still have to fully check this). I am a bit lost (not a system administrator at all) and would be grateful for any advice. Vincent

[Dovecot] DoveCot 2.0.9: Problem with some Clients and separator (migrate from Cyrus)
by Denny Schierz 23 Mar '11

23 Mar '11

hi, we had to move from a old dieing Sparc very quickly our Cyrus IMAP Users to Dovecot. Most things works, but some Clients (like Evolution or Thunderbird) are strange. Our separator in Dovecot2 is "^", the mailboxes on the filesystem are something like "INBOX.subfolder1.subfolder2", but in TB and Evo I see INBOX^subfolder1^subfolder^ In Roundcube Webmail, I have just a normal tree, as I expected. I used cyrus2dovecot.pl for converting. On Evolution I deleted the IMAP Profile and recreated it, and that was working, but it isn't a workaround for TB So, how can I fix it? namespace { type = private separator = ^ prefix = inbox = yes hidden = no subscriptions = yes } cu denny

[Dovecot] Master user creds for proxy stored statically/locally?
by Edward Carraro 22 Mar '11

22 Mar '11

I have successfully set up the master user on the destination server (2.0.11) and tests have worked. now I'm working on the proxy Before I had the proxy just forward everything to the backend and had the destination server do the authentication. My authentication is done via LDAP but not really sure how to append the master user and password to the users credentials after authentication is done. id rather not have the master user/pass in each users ldap entry and returned after doing a lookup or add a destuser field for each user... basically i prefer not having to add any new attributes to LDAP Can the information be stored locally in a file on the proxy? do i just make the same master user file that I have on the backend? Thanks!

[Dovecot] Change password cheme
by Pascal Nobus 22 Mar '11

22 Mar '11

We want to update our password scheme from crypt to SHA256. Because usernames/passwords are in MySQL I thought this wouldn't be a problem. We have about 3000 users that need to be updated, so make a new password for them isn't possible. I was thinking of an automated script that would update the database after every login. So we did this: dovecot.conf: mail_executable = /usr/local/etc/updatepwd.sh updatepwd.sh: #!/bin/sh $USER $PASSWORD|/usr/local/etc/do_updatepwd.pl exec /usr/local/libexec/dovecot/imap "$@" (do_updatepwd.pl is a perl script that makes a sha256 from the second argument, and then update the mysql-query) However: the password is not in the ENVIROMENT anymore. I changed in dovecot the settings: auth_debug = yes auth_debug_passwords = yes Anyone a solution for this? Best regards, Pascal

[Dovecot] http://wiki2.dovecot.org/MailServerOverview contains poppycock
by William Blunn 22 Mar '11

22 Mar '11

Just having another look at http://wiki2.dovecot.org/MailServerOverview , it seems to have some statements in it which are misleading, and some which are really ... well ... wrong. Quote: "With the possible, optional, exception of the deliver MDA, Dovecot is not involved with reception, delivery, and storage of mail. That function is provided by a MTA such as postfix <http://www.postfix.org>. It is the MTA that determines where and how mail is stored - Dovecot must then be configured to retrieve the mail accordingly." (Entered by user "amfes".) This contains a significant proportion of poppycock. Dovecot includes extensive functionality for the storage (as in the action of storing) of e-mail as well as retrieval, in the shape of the LDA. Using Dovecot's LDA is /required/ in the case of Dovecot-specific mail storage formats (sdbox, mdbox). With mbox, use of the Dovecot LDA is advisable since it will guarantee a locking strategy which is compatible with Dovecot's mail retrieval functionality. And in any case, use of the Dovecot LDA has merit in that it should guarantee line-up between the mailstore configurations used for storage and retrieval. It is NOT the MTA that determines where and how mail is stored. It is the PERSON who configures the system who decides this, and codifies that configuration into whatever systems carry out local delivery and retrieval. It IS true that use of Dovecot's LDA is optional, but to say that it is a "possible exception" is misleading. People /should/ use the Dovecot LDA if they are using Dovecot IMAP/POP, and the /option/ is to use the MTA's local delivery system /if/ it is so indicated on a particular system. Quote: "Again, it bears repeating, Dovecot /is not responsible for mail delivery or storage/. Any questions on these issues involve your MTA and MDA. Get those working first." (Entered by user "DanielMiller".) Again, contains quite a lot of misleading nonsense. "Mail delivery" includes the hand-off of the message by the MTA to the LDA, and the storage of the message by the LDA. The LDA should probably be Dovecot, so really Dovecot /is/ partially responsible for mail delivery. "Storage" involves that placing of message into the message store. This should be done by Dovecot, so Dovecot is responsible for this. Bill

[Dovecot] dsync inbox conversion problem (mbox -> mdbox)
by Sergiy Kyrylkov 22 Mar '11

22 Mar '11

Hi, We are trying to convert all mbox mail on our systems to mdbox using dsync, in order to be able to use email sub-folders in Thunderbird. Everything works fine for non-inbox folders, however the inbox folders are not getting converted. We used: *dsync -v convert mbox:~/mail:INBOX=/var/mail/%u* *dovecot --version* 2.0.beta6 (3156315704ef) (shipping with RHEL6/SL6) *dovecot -n* # 2.0.beta6 (3156315704ef): /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-71.18.2.el6.i686 i686 Scientific Linux release 6.0 (Carbon) mail_location = mdbox:~/mdbox mbox_write_locks = fcntl passdb { driver = pam } protocols = imap service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } Sergiy

[Dovecot] Request - please uncomment !include_try /etc/dovecot/local.conf in example config
by Ng Oon-Ee 22 Mar '11

22 Mar '11

Hi, could I request that the example config in doc/dovecot/example-config/dovecot.conf be slightly altered to uncomment the last line? The point of include_try is that it only includes if such a file exists, and doesn't break anything if the file does not exist. My distro (Arch) has a policy not to apply non-essential patches, rather asking users to forward requests upstream, hence this email. It allows users to simply keep a local.conf with all their settings and not have to worry that it would not be used when the dovecot package gets upgraded (which mostly means /etc/dovecot/dovecot.conf gets replaced, depending on packaging standards). Thanks.
