[Dovecot] Outlook FLAGS bug
by qmail＠top-consulting.net 14 Oct '10

14 Oct '10

I believe I have uncovered an Outlook bug. I've searched on the Internet a bit but I didn't find much on this particular topic. Basically it seems that Outlook (I'm using 2007) is overwriting message flags at least when replying to messages. I have seen the following behavior in the dovecot logs, first for only viewing a message, second when replying to a message. urfh UID STORE 65998 +FLAGS (\Seen) 3fxj IDLE DONE ejm4 UID STORE 65998 FLAGS (\Seen \Answered) The second STORE effectively wipes out any other flags on the message and replaces them with \Seen & \Answered I tried the same operation in Thunderbird and it performs properly. Anyone else encountered this bug ? Anyone knows if it's fixed in 2010 ?

Hi, ACL works fine now...

[Dovecot] Error on mailbox file
by augustocasagrande＠gmail.com 14 Oct '10

14 Oct '10

Hi! I'm running Postfix 2.2.9 as MTA. I have several mail clients , such as Outlook 2000/xp/2007. The clients comunicate to the MTA using pop3/smtp protocols. I have also installed Webmail Squirrel for the internet users. Squirrel needs an Imap server, so i have utilized Dovecot 1.2.6. To authenticate users , i use pam_winbbind to validate users to my NT domain. Here is my problem : Today i checked my /var/log/mail log and this took my attention : Sep 29 08:25:07 host1 dovecot: imap-login: Login: user=<USER>, method=PLAIN, rip=172.20.22.12, lip=172.20.22.14 Sep 29 08:25:07 host1 dovecot: IMAP(user): mail_location: mbox: mkdir(/home/NT-DOMAIN/user/mail) failed: Permission denied (euid=10188(user) egid=10001(domain users) missing +w perm: /home) Sep 29 08:25:07 host1 dovecot: IMAP(user): Fatal: Namespace initialization failed Here , i assume the user put his user name in CAPS (USER), and that i generating an error. Then Dovecot tries to create the directory /home/NT-DOMAIN/user/mail. In my dovecot.conf file , i have : mail_location = mbox:~/mail:INBOX=/var/mail/%u Now , the log continues : Sep 29 08:25:18 host1 dovecot: imap-login: Login: user=<user>, method=PLAIN, rip=172.20.22.12, lip=172.20.22.14 Sep 29 08:25:18 host1 dovecot: IMAP(user): mail_location: mbox: mkdir(/home/NT-DOMAIN/user/mail) failed: Permission denied (euid=10188(user) egid=10001(domain users) missing +w perm: /home) Sep 29 08:25:18 host1 dovecot: IMAP(user): Fatal: Namespace initialization failed Here the user re-enters the user, now correctly, but the problem persists . Finally , a could see this new log entry : Sep 29 10:50:43 host1 postfix/local[19663]: 50B98441E0: to=<user(a)domain.com>, orig_to=<user(a)domain.com>, relay=local, delay=0, status=bounced (cannot access mailbox /var/mail/user for user user. cannot open file: Permission denied) Here some user tries to send an email to this user , and a permission denied error occurs. Watching the permissions on the file : -rw------- 1 user users 1499655 2010-09-29 02:18 /var/mail/user Maybe some Dovecot process is blocking the file access ? List of Dovecot process: ps ax | grep dovecot 25997 ? Ss 0:07 /usr/sbin/dovecot 15399 ? S 0:02 dovecot-auth 20614 ? S 0:00 dovecot-auth -w How can i fix this issue? Thank you very much ! Augusto

[Dovecot] doveadm doesn't seem to honor mail_location, mail_uid, mail_gid
by Trever L. Adams 14 Oct '10

14 Oct '10

I am adjusting the recommended ldap configuration to match active directory instead of the standard posixaccount layout. The problem is that doveadm seems to ignore mail_uid and mail_gid along with (possibly) mail_location. This is a setup with all virtual users (all ldap, not system accounts). Everything works in postfix and standard dovecot operation, it is only doveadm which doesn't work. Ldap queries return everything but these entries (as they do not exist in AD). These items I have tried setting in the configuration and in environment variables. Any help would be GREATLY appreciated. Thank you, Trever -- "The three Rs of Microsoft support: Retry, Reboot, Reinstall." -- Unknown

Here is the relevant part from output of doveconf -n # 2.0.0: /usr/local/dovecot/etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.6 base_dir = /usr/local/dovecot/var/run/dovecot/ dict { expire = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } mail_plugins = quota acl expire virtual namespace { inbox = yes location = prefix = separator = . type = private } plugin { expire = Trash 7 Spam 30 expire_dict = proxy::expire } } protocol imap { mail_plugins = $mail_plugins imap_acl autocreate imap_quota } I have also created the database and tables for mysql and made the following change in dovecot-dict-sql.conf.ext file connect = host=localhost dbname=mails user=root password=xxxxxx map { pattern = shared/expire/$user/$mailbox table = expires value_field = expire_stamp fields { username = $user mailbox = $mailbox } } I am not getting any error in log file and expire is not working too please let me know the issue ... Thanks

[Dovecot] Why deliver+usercheck? deliver+MTA?
by Lukas Haase 14 Oct '10

14 Oct '10

Hi, I successfully configured dovecot using virtual users (and LDAP/AD). deliver is the LDA and verifies if the user exists (as recommended in the WIKI). However, the howtos in the Wiki say *nothing* about the case that the recipients should be verified *before* receiving the messages (prevent backscatter, ...). All configurations in the dovecot-Wiki (postfix and exim) just accept the mails and pass them to deliver. Also, all howtos which I found on the web. If the user does not exist, the mail is bounced because the mail was already accepted by the MTA. Nowadays this is an unacceptable configuration! Is there a special reason why there is no discussion about this? However, as postfix seems to be really too unflexible I have set up exim to handle incoming mail and do the usercheck in the router (with an LDAP query). But now the user is doubled-checked: Once when receiving with exim and a second time in deliver. This is not necessary, so I guess I can disable the LDAP query for deliver and set up a static userdb. Why does the Wiki recommened to verfify with deliver when the user needs to be checked at the MTA anyway? Regards, Luke

[Dovecot] Pigeonhole feature request: automatically copy sieve_global_path (default script) to user's sieve_dir
by Jerrale G 14 Oct '10

14 Oct '10

We have used the great managesieve you have merged together, with sieve, to create pigeonhole. However, when a user creates a custom script through a GUI of ours, the default, as we expected, would be ignored. Maybe you could add a retain_sieve_global=yes|no setting OR be more complex by having the sieve_global_dir copied to the users sieve_dir on first managesieve script save, if another setting to do this was set to yes. This way the administrators can create a skeleton directory and the users can retain the default skeleton settings. Maybe, in the future, you can do, just like the master auth for logging into users' imap accounts, you could have the master=yes allow login to each user's managesieve. Just some suggestions but, until a new feature comes around, I will have a cron job or a imap-login script do the trick. Timo has said that you are a separate developer from dovecot. I just want to thank you for the great job on sieve as well, Kudos, Jerrale G -- Jerrale G. SC Senior Admin

[Dovecot] Qmail+Vpopmail+Mysql+Dovecot 2.x (Notes on a successful conversion)
by Aaron 12 Oct '10

12 Oct '10

SoI had a hell of a time converting my qmail install to dovecot 2.0.5, so I thought I'd pass on what I learned. 1. When using vpopmail, do not use " --disable-many-domains". If you do, you'll need to recompile vpopmail without that setting and use the script found at http://qmailrocks.thibs.com/downloads/scripts/migrate-vpopmail-many-domains to collapse the tables. 2. Switch to mysql authentication. The following snippet works well. driver = mysql connect = host=/var/run/mysqld/mysqld.sock user=vpopmail password=YOURPASS dbname=vpopmail default_pass_scheme = PLAIN password_query = SELECT CONCAT(pw_name, '@', pw_domain) AS user, pw_clear_passwd AS password FROM vpopmail WHERE pw_name = '%n' AND pw_domain = '%d' user_query = SELECT pw_dir as home, 1008 AS uid, 1003 AS gid FROM vpopmail WHERE pw_name = '%n' AND pw_domain = '%d' 3. When integrating Sieve, vpopmail apparently needs to own auth-master and authdb. (example available on request) 4. If coming from maildrop as the LDA, you can put the following in your maildroprc to allow a gentler transition (or to keep maildrop's ability to call external applications) `test -r /usr/libexec/dovecot/deliver` if ( $RETURNCODE == 0) { `test -r $HOME/$EXT/.sieve` if ( $RETURNCODE == 0) { to "| /usr/libexec/dovecot/deliver -d $EXT@$USER" } } 5. When completely switching, you can either replace the .qmail files or use one of the following in qmail/control/defaultdelivery |/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d $EXT@$USER |/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d ${EXT/-*}@$USER -a $EXT@$USER -- This should allow a final conversion to vpopmail 5.5 (from 5.4.30) with dovecot 2.0.x.. I haven't done that final step yet, but it should now work. Anyhow, I hope this saves someone a few days of head scratching. a.

[Dovecot] Dovecot Version 1.2.12 Slow IMAP LIST Question
by Dave Shanefelter 11 Oct '10

11 Oct '10

We are using Dovecot 1.2.12, FreeBSD 8.1 Stable, & SquirrelMail 1.4.21 Our problem is that SquirrelMail works fine inside our Network, but from the outside SquirrelMail times out before it can display the inbox contents. SquirrelMail times out for everyone, all of the time. In troubleshooting we have observed the following: >From the inside, if I telnet into Dovecot IMAP and issue ? LIST "" "*" I get an instant list of my folders. If I do the above from the outside, the LIST command slowly lists 10 - 15 entries and stops, then pauses for what seems to be 30 seconds to a minute, then lists another 10 - 15 entries. After about 5 minutes of this it finally times out. An interesting note is, when it stops listing and pauses, it doesn't stop at the end of a line (folder entry), it stops half way through a line entry. For example, say the folder entry is mailfolder/folder1/folder2, when it stops I see mailfolder/fol I don't think this is a SquirrelMail issue because of the IMAP LIST problem. We have turned on debugging, but the logs really don't show much, just the timeout. Can anyone offer additional troubleshooting to help us track down this issue? Thanks

[Dovecot] ATTN TIMO: Man pages of "deliver"
by Jerrale G 11 Oct '10

11 Oct '10

The man pages of "man deliver" do not explain the "-n" option which is confusing a lot of people as to why mailboxes and mail folders aren't being automatically created; yet, the dovecot wiki's both say to use "-n" in postfix's master.cf which keeps dovecot's lda from automatically creating the folders. People are pulling hair over this! The default should be to not use -n as most will want their directories automatically created. The dovecot wikis, at least wiki1, also do not include the -e option to be more verbose to postfix, on error. Jerrale G.Jerrale G. SC Senior Admin

[Dovecot] login_* options for 1.0.15
by Hugo Monteiro 10 Oct '10

10 Oct '10

Hello all, Although i'm aware that version 1.0.15 is rather old, that's what is used in Lenny, so... Either way, the setup is rather simple, regular dovecot install, with maildirs residing on a "local" ext3 filesystem accessed through FC to a SAN (2Gbps link). The server has 2 cores (with HT), so "almost" 4 cores and 3GB of ram. A couple weeks ago we had a major number of account migrations, from POP to IMAP. We started to notice that in times of peaks, specially after lunch hour, dovecot started to get REALLY slow and closing client connections. A restart to the service was enough to get things working again. Firstly i thought about the max fd number per process, but after checking it turned out it was already rather large, 8192 in our case. I cannot observe any concerning I/O load either. Besides upgrading, are there any suggestions?

[Dovecot] Visible temp files as Imap Folder in INBOX
by Antonio Perez-Aranda 10 Oct '10

10 Oct '10

Hi all, I'm using dovecot-1.2.15 and NFS as storage of Maildir . When I try over IMAP and Evolution to move a mail to another Imap Folder, a file like .nfs000000000159816c0000245 is created and when move operation is finished, the file is deleted. Sometimes, this file isn't deleted and then, you can see a new imap folder called .nfs000000000159816c0000245 when you restart your Evolution or another Imap Client. Is this file created by dovecot? maybe, must dovecot delete this file on login? I think thats is easy fix this with a Post-Login script but I think that dovecot must delete it

[Dovecot] Segfault in dovecot-lda 2.0.5
by Sean Cardus 10 Oct '10

10 Oct '10

Hi, I've recently started using dovecot-lda to handle my local maildir deliveries from Exim. Unfortunately I've been experiencing the occasional failed delivery - My Exim logs were showing: Child process of virtual_dovecot_delivery transport (running command "/usr/local/libexec/dovecot/dovecot-lda -d $local_part@$domain -f $sender_address -a $original_local_part@$original_domain") was terminated by signal 11 (Segmentation fault) I originally thought a specific mail was causing the crash, but calling the command myself delivered the mail without any issues. However, I found if I ran a script that delivered the same mail 10 times, I could reliably cause multiple segfaults all with the following backtrace: #0 0x005581e9 in maildir_sync_set_new_msgs_count (ctx=0x0, count=1) at maildir-sync-index.c:50 No locals. #1 0x0055f3c0 in maildir_save_move_files_to_newcur (_ctx=0x85afe60) at maildir-save.c:857 files = {arr = {buffer = 0x8555a08, element_size = 4}, v = 0x8555a08, v_modifiable = 0x8555a08} mfp = 0x8555a2c new_changed = false mf = 0x85affa8 newdir = true #2 maildir_transaction_save_commit_pre (_ctx=0x85afe60) at maildir-save.c:951 _data_stack_cur_id = 3 ctx = <value optimized out> _t = 0x85af500 sync_flags = <value optimized out> ret = <value optimized out> __FUNCTION__ = "maildir_transaction_save_commit_pre" #3 0x00555e8f in index_transaction_index_commit (index_trans=0x85af540, result_r=0xbfd78510) at index-transaction.c:27 it = 0x85af500 ibox = 0x858a108 ret = <value optimized out> __FUNCTION__ = "index_transaction_index_commit" #4 0x00595c11 in mail_index_transaction_commit_full (_t=0xbfd78528, result_r=0xbfd78510) at mail-index-transaction.c:237 t = 0x85af540 index = 0x85835e0 index_undeleted = false #5 0x00556284 in index_transaction_commit (t=0x85af500, changes_r=0xbfd785a8) at index-transaction.c:123 box = 0x8589ef0 itrans = 0x0 result = {log_file_seq = 0, log_file_offset = 0, commit_size = 0, ignored_modseq_changes = 0} ret = <value optimized out> #6 0x00533122 in mailbox_transaction_commit_get_changes (_t=0xbfd785d4, changes_r=0xbfd785a8) at mail-storage.c:1215 _data_stack_cur_id = 2 t = 0x85af500 ret = <value optimized out> #7 0x00a7eaef in mail_deliver_save (ctx=0xbfd786f8, mailbox=0x804ab55 "INBOX", flags=0, keywords=0x0, storage_r=0xbfd78794) at mail-deliver.c:219 open_ctx = {user = 0x85781b0, lda_mailbox_autocreate = false, lda_mailbox_autosubscribe = false} box = 0x8589ef0 trans_flags = <value optimized out> t = 0x0 save_ctx = 0x0 kw = 0x0 error = MAIL_ERROR_NONE mailbox_name = 0x804ab55 "INBOX" errstr = <value optimized out> changes = {pool = 0x85b5998, uid_validity = 0, saved_uids = {arr = {buffer = 0x85b59a8, element_size = 8}, v = 0x85b59a8, v_modifiable = 0x85b59a8}, ignored_modseq_changes = 0} range = <value optimized out> ret = 0 __FUNCTION__ = "mail_deliver_save" #8 0x00a7edf8 in mail_deliver (ctx=0xbfd786f8, storage_r=0xbfd78794) at mail-deliver.c:289 ret = -1 #9 0x0804a124 in main (argc=139843496, argv=0x855d1b8) at main.c:429 set_roots = {0x804b390, 0x0} ctx = {pool = 0x855d7a8, set = 0x855ef48, dup_ctx = 0x0, session_id = 0x0, src_mail = 0x85856e0, src_envelope_sender = 0x855d7b8 "sean(a)cardus.com", dest_user = 0x85781b0, dest_addr = 0x855d228 "sean(a)cardus.com", final_dest_addr = 0x855d228 "sean(a)cardus.com", dest_mailbox_name = 0x804ab55 "INBOX", dest_mail = 0x0, tried_default_save = true, saved_mail = false, save_dest_mail = false} service_flags = 1027 user = 0x1 <Address 0x1 out of bounds> errstr = <value optimized out> path = 0x0 storage_service = 0x855e3b0 service_user = 0x855ec70 service_input = {module = 0x804ab3c "lda", service = 0x804ab3c "lda", username = 0x855d202 "sean(a)cardus.com", local_ip = {family = 0, u = {ip6 = {in6_u = { u6_addr8 = '\000' <repeats 15 times>, u6_addr16 = {0, 0, 0, 0, 0, 0, 0, 0}, u6_addr32 = {0, 0, 0, 0}}}, ip4 = {s_addr = 0}}}, remote_ip = {family = 0, u = { ip6 = {in6_u = {u6_addr8 = '\000' <repeats 15 times>, u6_addr16 = {0, 0, 0, 0, 0, 0, 0, 0}, u6_addr32 = {0, 0, 0, 0}}}, ip4 = {s_addr = 0}}}, userdb_fields = 0x0} raw_mail_user = 0x857c1b8 raw_ns = 0x8571ea8 raw_ns_set = {name = 0x0, type = 0x0, separator = 0x0, prefix = 0x0, location = 0x804abd9 ":LAYOUT=none", alias_for = 0x0, inbox = false, hidden = false, list = 0x0, subscriptions = false, user_set = 0x0} storage = <value optimized out> box = 0x85801c0 raw_box = <value optimized out> input = 0x0 t = 0x8584d90 headers_ctx = 0x0 user_source = 0x804ab2c "" sets = <value optimized out> process_euid = <value optimized out> stderr_rejection = false mtime = -1 ret = <value optimized out> c = <value optimized out> error = <value optimized out> Any ideas?

[Dovecot] migrate machines and upgrade
by Donny Brooks 08 Oct '10

08 Oct '10

I am about to be migrating mail servers and have a few questions. First a little background: Old mail server: Fedora 11 dovecot-1.2.11-3.fc11.x86_64 installed from yum repo mbox mail format OpenLDAP authentication 250+ users New mail server: Fedora 13 dovecot-2.0.1-1_118.fc13.x86_64 installed from atrpm rpm file Maildir mail format OpenLDAP authentication 250+ users I plan to use dsync on the new machine to migrate the mail off the old machine and mbox format to the new machine and Maildir. I think I read where I can do the migration without interfering with normal mail delivery and then when i get ready to do the final move I just kill dovecot on the old machine, dsync once more, and start the service on the new machine. What would be the best way to accomplish this? And as for the configuration changed between 1.2.11 and 2.0.1, where to start? I see there is now a conf.d directory for 2.0.1. How will this tie in to the 1.2.11 config? Any pointers there? Other option is to move the mbox mail as it sits to the new machine, install 1.2.X branch dovecot on new machine, and let the convert plugin do all the work. However I like the idea of the dsync doing the sync with minimal downtime. Thanks in advance. -- Donny B.

Hello, I reported a while back that it wasn't possible to compile the whole of Dovecot using gcc 4.5.2 and the new gold linker, but it's now working with recent snapshots of both binutils and GCC. Cheers, Olivier

[Dovecot] Significant performance problems
by Chris Hobbs 07 Oct '10

07 Oct '10

Hi all, I'm sure my issues are a result of misconfiguration, but I'm hoping someone can point me in the right direction. I'm getting pressure to move us back to GroupWise, which I desperately want to avoid :-/ We're running dovecot 1.2.9 on Ubuntu 10.4 LTS+postfix. The server is a VM with 1 vCPU and 4GB of RAM. We serve about 10,000 users with anywhere from 500-1000 logged in at any one time. Messages are stored in Maildir format on two NFS servers (one for staff, the other for students). Today I implemented the "High performance" setup described here: http://wiki.dovecot.org/NFS (mainly moving indexes off of NFS, since I'm only using the one server). I also added imapproxy to our webmail client server (SOGo). The vast majority of our users come in over the web. We currently see load averages spiking into the 20-30 range. When this happens, service crawls to a near standstill, and ultimately the SOGo client starts crashing out. I'm wondering if anything jumps out at anybody here - feel free to mock if/when you find an obvious configuration problem. I just want it to work :-) dovecot -n # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-25-server x86_64 Ubuntu 10.04.1 LTS log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s managesieve listen(default): * listen(imap): * listen(pop3): * listen(managesieve): *:2000 ssl_cert_file: /etc/dovecot/certs/mail_nhusd_k12_ca_us.crt ssl_key_file: /etc/dovecot/certs/mail_nhusd_k12_ca_us.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login login_process_per_connection: no login_process_size: 512 login_processes_count: 20 login_max_processes_count: 3000 login_max_connections: 64 max_mail_processes: 2048 mail_max_userip_connections(default): 20 mail_max_userip_connections(imap): 20 mail_max_userip_connections(pop3): 10 mail_max_userip_connections(managesieve): 10 mail_access_groups: staffmailusers mail_privileged_group: dovecot mail_uid: mail mail_gid: 502 mail_location: maildir:~/Maildir:INDEX=/var/indexes/%u mail_nfs_storage: yes mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): acl imap_acl quota imap_quota expire mail_plugins(imap): acl imap_acl quota imap_quota expire mail_plugins(pop3): mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: shared separator: / prefix: shared/%%u/ location: maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u list: children lda: deliver_log_format: %$ -- FROM=%f SUBJECT=%s mail_plugins: cmusieve acl expire log_path: info_log_path: syslog_facility: mail postmaster_address:postmaster@nhusd.k12.ca.us hostname: mail.nhusd.k12.ca.us auth_socket_path: /var/run/dovecot/auth-master auth default: passdb: driver: pam passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 plugin: quota: maildir:User quota quota_rule: *:storage=9G quota_rule2: Trash:storage=200M acl: vfile acl_shared_dict:file:/home/staff/dovecot/shared-mailboxes expire: Trash 7 Trash/* 7 Spam 30 expire_dict: proxy::expire sieve: ~/.dovecot.sieve sieve_dir: ~/sieve sieve_extensions: +imapflags dict: expire: mysql:/etc/dovecot/dovecot-dict-expire.conf -- Chris Hobbs Director, Technology New Haven Unified School District -- This message was scanned by ESVA and is believed to be clean.

[Dovecot] And again... too many open files
by Joseba Torre 07 Oct '10

07 Oct '10

Hi! Two days ago I upgraded to 1.2.15, and again I the warning "Warning: fd limit 1024 is lower than what Dovecot can use under full load" reappeared. It's a bit weird, because my actual limits are higher. From /etc/security/limits.conf * soft nofile 4096 * hard nofile 8192 root soft nofile 4096 root hard nofile 8192 dovecot soft nofile 4096 dovecot hard nofile 8192 I added the * lines to avoid problems if a new user was involved, and finally supposed it was a bug in the detection process. Today, as expected, dovecot was not responding with the famous "Too many open files" error. Has something changed? Is there some way to know which is the maximum number of files that can be open? Is there some parameter I can change to avoid this? Here's my dovecot -n # 1.2.15: /usr/local/etc/dovecot.conf # OS: Linux 2.6.18-164.11.1.el5 x86_64 Red Hat Enterprise Linux Server release 5.4 (Tikanga) syslog_facility: local1 protocols: imap imaps pop3 pop3s listen(default): *:143 listen(imap): *:143 listen(pop3): *:110 ssl_listen(default): *:993 ssl_listen(imap): *:993 ssl_listen(pop3): *:995 ssl_cert_file: /usr/share/ssl/certs/imapd.pem ssl_key_file: /usr/share/ssl/certs/imapd.pem disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_process_per_connection: no login_process_size: 256 login_processes_count: 16 login_max_processes_count: 256 login_max_connections: 512 max_mail_processes: 2048 first_valid_uid: 100 mail_location: maildir:~/Maildir:INDEX=/var/dovecot/%u:CONTROL=/var/dovecot nas/%u/control mail_nfs_storage: yes lock_method: dotlock mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %v.%u auth default: cache_size: 1000 cache_ttl: 6000 master_user_separator: * debug: yes passdb: driver: passwd-file args: /usr/local/etc/bloqueados deny: yes passdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf passdb: driver: passwd-file args: /usr/local/etc/shadow passdb: driver: pam passdb: driver: passwd-file args: /usr/local/etc/dovecot-master.conf master: yes userdb: driver: prefetch userdb: driver: passwd-file args: /usr/local/etc/passwd userdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 plugin: quota: fs -- Joseba Torre.

[Dovecot] dovecot-1.2.12 core
by Thomas Hummel 07 Oct '10

07 Oct '10

Hi Timo, just to report that . dovecot-1.2.12 which ran fine for several month . on FreeBSD 7.2-STABLE (/usr/obj/usr/src/sys/GENERIC amd64) . using Maildir (mailboxes, control and indexes on NFS) has crashed this morning on our server. I found nothing special in the logfile. Attached are dovecot -n output and a gdb backtrace of the core file. Thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] User authentication fields size limit
by Andre Nathan 06 Oct '10

06 Oct '10

Hello I'm using authentication via SQL, and I'm storing the full mail_location in the database. This is a long string because we're using multiple partitions and hashing to create this path. It looks like this: # doveadm user andre=sneakymustard.com userdb: andre=sneakymustard.com password : $1$ixW87UeD$fLhORaJS0c5wNFmWqfJdI1 mail : mdbox:/var/spool/imap/partition7/11/andre=sneakymustard.com:INDEX=/var/lib/… quota_rule: *:bytes=1024M Depending on the user's email, this string can be even longer. What I've noticed is that it is truncated when it reaches 128 bytes. Could this size limit be increased? Thanks, Andre

[Dovecot] dovecot-2.0-pigeonhole-0.2.1 installation in wrong lib dir?
by Wolfgang.Friebel＠desy.de 06 Oct '10

06 Oct '10

I am building dovecot-2.0-pigeonhole-0.2.1 (dovecot-2.0.5, but that does not matter) with dovecot-config in place (in /usr/lib64/dovecot) on a 64bit Linux (RHEL5): ./configure --with-dovecot=/usr/lib64/dovecot The libs needed for several executables in libexec such as /usr/libexec/dovecot/managesieve-login are not installed in /usr/lib64 but in /usr/lib64/dovecot. Therefore the executable will fail to run: ldd /usr/libexec/dovecot/managesieve-login libdovecot-login.so.0 => not found libdovecot.so.0 => not found librt.so.1 => /lib64/librt.so.1 (0x00000032e9600000) libc.so.6 => /lib64/libc.so.6 (0x00000032e8200000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00000032e8e00000) /lib64/ld-linux-x86-64.so.2 (0x00000032e7e00000) To me this looks like a bug in the generated Makefile. I could easily fix that by providing the library path for the loader or by symlinks in /usr/lib64, but this is a workaround only. When doing the fix then managesieve works as expected (tested against my patched websieve using GSSAPI) -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany

06 Oct '10

During norml operation this morning we're seeing a significantly increased load on the IMAP server (factor 5, from 5 to 25). Does dovecot need to rebuild index files or perform other IO intensive operations after the upgrade? We're using Maildir Our monitoring shows increased "system" time. We're runnign fewer processes, the IO rate ist identical to yesterday, memory usage is identical. -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

First of all, i have virtual users, with virtual domains. Mail is stored in /usr/local/virtual/domain name/user So if my domain is domain.com and my e-mail address is johan(a)domain.com the directory is /usr/local/virtual/domain.com/johan i followed the wiki, and my configuration looks like the following. beasty dovecot # dovecot -n # 2.0.5: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.1-STABLE amd64 ufs auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login auth_verbose = yes dict { acl = mysql:/usr/local/etc/dovecot/dovecot-dict-acl-sql.conf quotadict = mysql:/usr/local/etc/dovecot/dovecot-dict-quota.conf } disable_plaintext_auth = no first_valid_gid = 1004 first_valid_uid = 1004 last_valid_gid = 1004 last_valid_uid = 1004 log_timestamp = .%Y-%m-%d %H:%M:%S . mail_access_groups = vmail mail_debug = yes mail_gid = 1004 mail_location = maildir:/usr/local/virtual/%d/%n mail_uid = 1004 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 mbox_write_locks = fcntl namespace { hidden = no inbox = yes list = yes location = prefix = separator = / subscriptions = yes type = private } namespace { inbox = no list = children location = maildir:/usr/local/virtual/%%d/%%n/shared/:INDEX=/shared/%%n prefix = shared/%%d/%%u/ separator = / subscriptions = no type = shared } passdb { args = /usr/local/etc/dovecot/dovecot-mysql.conf driver = sql } plugin { acl = vfile acl_anyone = allow acl_shared_dict = proxy::acl autocreate = Trash autocreate2 = Junk autocreate3 = Sent autocreate4 = Drafts autocreate5 = Templates autosubscribe = Trash autosubscribe2 = Junk autosubscribe3 = Sent autosubscribe4 = Drafts autosubscribe5 = Templates quota = dict:::proxy::quotadict quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2 = storage=80%% /usr/local/bin/quota-warning.sh 80 } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = vmail mode = 0660 user = vmail } } service dict { unix_listener dict { mode = 0600 user = vmail } } service imap-login { inet_listener imap { address = 192.168.50.200 port = 143 } } service pop3-login { inet_listener pop3 { address = 192.168.50.200 port = 110 } } ssl = no userdb { args = /usr/local/etc/dovecot/dovecot-mysql.conf driver = sql } protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep imap_idle_notify_interval = 2 mins imap_logout_format = bytes=%i/%o imap_max_line_length = 64 k mail_plugins = quota imap_quota autocreate acl imap_acl mail_log notify } protocol pop3 { mail_plugins = quota trash pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } protocol lda { auth_socket_path = /var/run/dovecot/auth-master mail_plugins = quota acl mail_log notify postmaster_address = postmaster(a)test.com sendmail_path = /usr/local/sbin/sendmail } That is my config file.

[Dovecot] Imap Folder activity detect
by Antonio Perez-Aranda 06 Oct '10

06 Oct '10

Hi all, We are migrating a mail service with 80.000 users, and 40.000 of them are using IMAP. At present, this service is handled by Courier, with some custom patches. And we are migrating to Dovecot 1.2.15. One of these patches is used to interact with Spamassassin. If Courier detects any move/copy operation to the "IsSPAM" or "IsntSPAM" folders, a specific bash script is executed like IsSPAM.sh and IsntSPAM.sh These scripts do the following: IsSPAM.sh 1. Takes user as parameter USER. 2. Retrieves the homeDirectory of USER from ldap, using ldapsearch. 3. Executes /usr/bin/sa-learn --spam ... with IsSPAM folder IsntSPAM.sh 1. Takes user as parameter USER. 2. Retrieves the homeDirectory of USER from ldap, using ldapsearch. 3. Executes /usr/bin/sa-learn --ham ... with IsntSPAM folder 4. Moves all content from IsntSPAM to INBOX I think that it shouldn't be very hard to implement a plugin to detect MOVE/COPY events to specified folders, and to execute specified scripts on detection. Is there already such a plugin for dovecot 1.2.15?

[Dovecot] How to add the missing maildir folders
by Egbert Jan van den Bussche 06 Oct '10

06 Oct '10

Hi fellow list members, What would be the best way to add the .Sent,.Draft, etc. folders to the maildir tree? It seems not Dovecots task to do that but of the MUA. I have seen several options. Use of skel but that works only for new system users. I have only virtual users preloaded in a database. I've discoverred that ONLY Roundcube add the folders (if configured to do that) but I've not been able to have the folders created by Thunderbird. Yes, you can manage the subscribtions to folders but there is no way to create them. I did not bother to try Outlook... MY users use pop3, imap and web (Roundcube) but I cannot ask them to use Roundcube first, just to create the folders. I have no such thing as maildrop, which seems to be able to create folders. Should I run some script during login? How? TIA Egbert Jan (NL)

[Dovecot] Feature request for maildir style boxes
by David Ford 06 Oct '10

06 Oct '10

greetings, i'd like to ask for a certain feature request. dovecot:maildir_uidlist_recreate() to set the gid of new files based on the parent directory group ownership and normally that's desired, an appropriate security method. on our server, we use directory permissions to more stringently isolate access between users and services. we have three group ids used for this, and i'll use my name as example. Oct 05 13:44:30 imap(david): Error: fchown(/home/david/.maildir/dovecot-uidlist.tmp, -1, 497(net-mail)) failed: Operation not permitted (egid=1234(david), group based on /home/david/.maildir) Colt log # ls -ld /home/ /home/david /home/david/public_html/ /home/david/.maildir /home/david/.maildir/cur|awk '{printf "%s %5s %9s %s\n", $1,$3,$4,$9}' drwxr-xr-x root root /home/ drwx--x--- david net-all /home/david drwxr-x--- david net-mail /home/david/.maildir drwx------ david david /home/david/.maildir/cur drwxr-x--- david net-web /home/david/public_html/ the purpose of this is to prevent undesired access to personal files. users cannot 'cd' or 'ls' in other user's home directories, mail stores, or web files. apache, procmail, dovecot et cetera, are in the appropriate groups and therefore have access needed to do file ops. however, they're limited to their appropriate stores. as mentioned at the beginning, dovecot tries to match the gid of the parent directory for new files and normally, that's desired and expected behavior, but in our case. dovecot creates the file as uid/gid of the user, so the knob can either ignore the failure to set gid per the parent and not log it, or not attempt to set the gid per parent in the first place. src/lib-storage/index/maildir/maildir-uidlist.c 1412: if (box->file_create_gid != (gid_t)-1 && fchown(fd, (uid_t)-1, box->file_create_gid) < 0) { if (errno == EPERM) { mail_storage_set_critical(box->storage, "%s", eperm_error_get_chgrp("fchown", temp_path, box->file_create_gid, box->file_create_gid_origin)); } else { mail_storage_set_critical(box->storage, "fchown(%s) failed: %m", temp_path); } } to something like: ( "new_files_inherit_parent_gid = true" ) if (box->file_create_gid != -1 && --> box->new_files_inherit_parent_gid) { fchown(fd, -1, box->file_create_gid) ... } bool new_files_inherit_parent_gid [default true] could be added the following for example: src/lib-storage/mailbox-list-private.h:struct mailbox_list src/lib-storage/mail-storage-private.h:struct mailbox this block of code appears in similar instances for a number of other occasions (and could be made a more global function), but not all files in ~/.maildir/* appear to use a function like this. the uidvalidity functions are a little different for example. == for a busy mail server, that's a lot of excess logging and pollution when trying to review nightly logs for issues :) thank you for the consideration, -david

Hello, There is the autocreate plugin[1], but the problem is that a user cannot delete those mailboxes. It can be a problem for people using clients in different languages and that want mailboxes in these languages. I would be great if Dovecot could make some of these automatic mailboxes optional.

[Dovecot] release plan for dovecot antispam plugin?
by Tom Hendrikx 06 Oct '10

06 Oct '10

Hi, I noticed that someone took over the development of the dovecot antispam plugin, and the is currently hosted at dovecots hg repo. Great to see that the plugin is not dead! ;) I created a gentoo ebuild that builds the plugin from the repo, and the plugin seems to work nice with dspam (using mailtrain backend). I'm running a checkout from Tue Sep 21 16:14:48 2010. However, it is lacking a release so distributions can also easily update the plugin. Is there any news on this? Regards, Tom

[Dovecot] LMTP proxy too many DATA output timeout (perhaps)
by Luca Palazzo 05 Oct '10

05 Oct '10

Hi All, we are getting a lot of this message from dovecot director. They seem to be too many. Backend servers do not log anything and postfix logs a lot of these errors. It seems that dovecot strategy handgling data output timeout when proxying LMTP is or too aggressive or may have some other problem. This error generate sometime a lot of dupicate deliveries, probably because meanwhile real server has finished delivering the mail, proxy drops the connection. Another symptom, maybe related to duplicate uid patch, is that we are receiving blank email. What may I look further? Regards Luca

[Dovecot] Proxying LMTP - Auth PASS lookup failed
by Edward Carraro 05 Oct '10

05 Oct '10

I'm trying to configure my proxy/director server, which proxies imap/pop/managesieve correctly already, to proxy LMTP to my backend message store server (dovecot+postfix already configured there) This is what I have so far: 10-auth.conf using auth-static.conf.ext instead of auth-ldap.conf.ext (switching to this made proxying imap/pop/managesieve work) 10-director.conf protocol lmtp { auth_socket_path = /usr/local/var/run/dovecot/director-userdb } 10-master.conf (changed user from vmail to dovecot as it was giving permission denied error before -- on the backend dovecot server this is still 'vmail') unix_listener auth-userdb { mode = 0600 user = dovecot } 20-lmtp.conf lmtp_proxy = yes auth-static.conf.ext passdb { driver = static args = proxy=y nopassword=y } my dovecot logs show: auth: Debug: password(user(a)dev.domain.com): passdb doesn't support credential lookups lmtp(1261): Error: user user(a)dev.domain.com: Auth PASS lookup failed postfix show: [private/dovecot-lmtp] said: 451 4.3.0 <user(a)dev.domain.com> Temporary user lookup failure (in reply to RCPT TO command) Any ideas?

[Dovecot] Another dovecot-lda / deliver Segfault
by Michael P 05 Oct '10

05 Oct '10

I just upgraded from 1.2.11 to 2.0.5. When I send mail from a virtual local user, to another virtual local user, the email sends fine (passing though postfix, then amavisd, then to dovecot deliver) and the recipient receives it, but during this deliver segfaults (pointing to libdovecot.storage.0.0.0) and sends an undeliverable message back to the original sender. This does not happen if someone outside the localdomain sends mail, and does not happen sending from local to a remote address, just purely from virtal to virtual locally.

[Dovecot] question on quota configuration on 2.0.5

Hi, On dovecot 1.2 i had the following configuration on my dovecot-sql.conf file: password_query = select endereco as user, password, '/var/spool/mail/%u' as userdb_home, 'maildir:/var/spool/mail/%u' as userdb_mail, 8 as userdb_uid, 12 as userdb_gid, concat('*:storage=', quota) as userdb_quota_rule, 'Trash:storage=100M' as userdb_quota_rule2 from emails where endereco = '%u' and ativa = '1' special attention to 'Trash:storage=100M' as userdb_quota_rule2 after migrating to 2.0.5, i got this warning on the logs: Oct 3 16:06:41 ns2 dovecot: imap(user(a)domain.com), rip=127.0.0.1, lip=127.0.0.1: Warning: quota root User quota rule Trash:storage=100M: obsolete configuration for rule 'storage=100M' should be changed to 'storage=+100M' Oct 3 16:08:09 ns2 dovecot: imap(user(a)domain.com), rip=127.0.0.1, lip=127.0.0.1: Error: quota: Unknown namespace: Trash about changing 100M to +100M, that's OK, no problem .... but even after changing that, i still keep getting the 'unknown namespace' message. question: what's the correct way of doing this configuration on dovecot 2.0 ? The idea of this configuration is to give plus 100M of the user's quota on the Trash folder, thus avoiding problems with out webmail which copies messages to trash before erasing from the actual folder. -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

[Dovecot] v1.2.15 released
by Timo Sirainen 05 Oct '10

05 Oct '10

http://dovecot.org/releases/1.2/dovecot-1.2.15.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.15.tar.gz.sig See the "ACL handling bugs" message for more details about the ACL merging bug. * acl: Fixed the logic of merging multiple ACL entries. Now it works as documented, while previously it could have done slightly different things depending on the order of the entries. * acl: Don't give admin rights to all owner mailboxes. This was originally done to make sure that mailbox owner couldn't accidentally remove their own admin rights. But this is already prevented by SETACL command, so it's not necessary. Also sysadmin may have intentionally removed some admin rights from some mailboxes (especially when using symlinked shared mailboxes). - Maildir: Fixed potential "Duplicate file entry" in dovecot-uidlist file errors. - Maildir: Avoid unnecessary uidlist recreation during mail delivery. - imap: When SELECT fails, it didn't close the previous mailbox. - Dovecot master process could have died if it got SIGCHLD signals very rapidly while it was trying to log. This could have happened for example if a lot of imap/pop3 sessions disconnected at the exact same time.

[Dovecot] deliver and time
by Rick Romero 05 Oct '10

05 Oct '10

Hi All, I've been experimenting with deliver on my personal domain, and so far everything has been peachy except for Mail.app. Mail.app (on multiple devices) is showing what looks to be GMT times, rather than the date header. Initially I thought it was something I did on my Mac, until I got an Ipad to test with - and never connected it to my Mac - and had the same time issue. It seems Mail.app uses the timestamp ('arrived date'?) on the mail file itself (Maildir here) to display the time. So.. I have dovecot 1.2.10 installed on top of vpopmail (multiple MXs, delivering to OpenSolaris NFS share via tcp), and it seems that deliver is using the GMT time when writing the Maildir file, and vdelivermail just uses the adjusted time.. Or maybe it just allows the OS to write the timestamp. Either way, is this a known issue with deliver - or is there a patch? I don't recall ever seeing it come up on the list, and I'm not seeing anything in the changelog. Rick

[Dovecot] Released Pigeonhole Sieve v0.1.18 and ManageSieve v0.11.12 for Dovecot v1.2.15
by Stephan Bosch 05 Oct '10

05 Oct '10

Hello Dovecot users, The recent release of Dovecot v1.2.15 is a good opportunity to release new versions of Sieve and ManageSieve for Dovecot v1.2. These releases consist entirely of bugfixes and introduce no new features. Changelog Sieve v0.1.18: - Imap4flags: fixed segfault bug occuring in multiscript context. Occured in specific situations when a script using imap4flags was followed in the sequence by scripts not using imap4flags. - Imap4flags: fixed bug in setflag command; when parameter was a stringlist, only the last item was actually set. - Prevented assertion failure due to currupt binary string representation. If the string were missing a final \0 character an assertion was produced in stead of a binary corruption error. - Multiscript: fixed duplicate implicit keep caused by erroneous execution state update. - Fixed Sieve script name checking to properly handle length limit and added 0x00ff as invalid character. - Removed spurious old stdio.h (top) includes; these caused compile issues on specific systems. - Fixed default Sieve capability (as reported by ManageSieve): extra extensions spamtest, spamtestplus and virustest were enabled by default. These should, however, only be enabled when properly configured and there is no default configuration. - Variables extension: fixed :length set modifier to recognize utf8 characters in stead of octets. - Fixed unnecessary reporting of dummy extensions in ManageSieve SIEVE capability; the comparator-i;octet and comparator-i;ascii-numeric 'extensions' were reported explicitly. - LDA Sieve plugin: added _version symbol to enable Dovecot's plugin version check. Without this check, people can forget to recompile the plugin, which can lead to unexpected effects. Changelog ManageSieve v0.11.12: - Fixed error handling of PUTSCRIPT commmand; save commit errors would not make the command fail. - Fixed PUTSCRIPT bug causing it to hang when given an empty script name. The releases are available as follows: Sieve http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.18.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.18.tar.gz.sig ManageSieve http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.12.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.12.tar.gz.… ManageSieve patch http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.15-managesieve-0.11.12.diff… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.15-managesieve-0.11.12.diff… Refer to http://pigeonhole.dovecot.org and the Dovecot wiki for more information.

[Dovecot] [2.0.5] quota in maildirsize doesn't work with mdbox
by interfaSys sàrl 04 Oct '10

04 Oct '10

Hello, I'm using mdbox to store messages and maildirsize to store quotas I have the following in my dovecot.conf mail_plugins = quota trash zlib fts fts_squat imap_quota imap_zlib antispam quota = maildir:User quota quota_rule = ?:storage=1G quota_rule2 = Trash:storage=+10%% I noticed that the quotas were wrong, so I sent myself some emails in hope of seeing the ratio change to the correct values, but the amount of used space changed to the total of what was just received, not the total of what was in the mailbox. So I tried to recalculate the quota using doveadm quota recalc, but it didn't help, instead of recalculating the amount of used space, it just wrote 0 0 to maildirsize. Do I have a config problem or is someting broken in Dovecot? Cheers, Olivier

Now it works as documented, while previously it could have done slightly different things depending on the order of the entries. * virtual: Allow opening virtual mailboxes that refer to non-existing mailboxes. It seems that the benefits of this outweigh the lack of error message when typoing a mailbox name. + Added some disk I/O optimizations to Maildir and index code. They're especially helpful with short-lived connections like POP3. + pop3: Added pop3_fast_size_lookups setting. - doveconf sometimes failed with complaining about missing ssl_key setting, causing e.g. dovecot-lda to fail. - lda: If there's an error in configuration, doveconf didn't exit with EX_TEMPFAIL as it should have. - sdbox: Fixed memory leak when copying messages with hard links. - zlib + sdbox combination didn't work - zlib: Fixed several crashes, which mainly showed up with mbox. - quota: Don't crash if user has quota disabled, but plugin loaded. - doveadm fetch uid was actually returning sequence, not uid. - v2.0.4's subscription listing ignored (and logged a warning about) subscriptions=no namespaces' entries in some configurations. (So listing shared mailboxes' subscriptions could have been broken.) - acl: Fixed crashing when sometimes listing shared mailboxes via dict proxy.

[Dovecot] Setting up the Director
by Jason 'XenoPhage' Frisvold 04 Oct '10

04 Oct '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I'm trying to wrap my head around the Director and how it works, but I'm not having much luck finding documentation. Currently, I have two front end mail servers that use NFS for mail storage. I'm using Cisco's SLB for load balancing, though I may switch over to a server-based load balancing solution at some point. SLB works great, but it doesn't guarantee that a given user will stick to the same server. At least, not as it's configured now.. But, regardless, I want to move away from SLB so I can have a bit more control. If I want to implement the Director, do I need to have additional machines, or does it get configured on the front end mail machines? I'm thinking the former, but hoping for the latter.. :P Does anyone know of a really good write-up about the director and how it works? thanks, - --------------------------- Jason 'XenoPhage' Frisvold xenophage(a)godshell.com - --------------------------- "Any sufficiently advanced magic is indistinguishable from technology." - - Niven's Inverse of Clarke's Third Law -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.14 (Darwin) iEYEARECAAYFAkypPLcACgkQ8CjzPZyTUTT+/QCfUpOS4mdc6hMCZLXAYIlnfOdL XfcAmgIH0n1peB1qHKSfIps0wQ8dbHxF =h8Xt -----END PGP SIGNATURE-----

I've only experienced this with Thunderbird...maybe the "regular" berries have not configured their BIS accounts properly? The only problem I'm aware of with Blackberry devices is that if the BIS servers can't login because Dovecot is being upgraded (version mismatch), then they'll go into polling mode (no more instant emails).

[Dovecot] SASL auth and proxy
by mailing＠securitylabs.it 02 Oct '10

02 Oct '10

Hello, I'm finding a way to have a pool of smtp-auth servers in front of my actuals servers to permit relay to our customers. Now users sends emails connecting to the right IP via mail.domain.tld, with authentication. Every server has it's own user database in mysql. I'd like to have a pool of server (with round robin, ideally with postfix + sasl + dovecot) that authenticate the users with the actuals servers and then pointing mail.domain.tld to this pool and not to one server. My trouble is how to authenticate users. Can I use: http://wiki.dovecot.org/Authentication/MultipleDatabases to tell Dovecot to authenticate with every MySQL database on the servers "behind"? If yes, is there a better way to do this considering I'm already using some proxy machines (dovecot) for pop3/imap and so I already have a db with domain.tld -> IP of the server? I also have some machine without a MySQL DB for users (vpopmail + cdb), so the option with MultipleDatabases will be good only for some machines. Something similar to the proxy mechanism that I already use for pop3/imsp will be good: the proxy connect to the machine behind that do the authentication, I only need a table with domain -> server IP (that I already have). Thanks for any advice.

I'm wondering now is it even possible to use the same mbox's from 0.99.13-3 with version 1.0.15-2? Is there a procedure documented somewhere? Any pointers would be much appreciated.

[Dovecot] dovecot 2.04 broke folder sharing

Hi Timo, upgrading from 2.03 to 2.04 broke folder sharing at my setup double checked this with tests reverting versions etc setting acl and subcriptions are working with 2.04, but in difference to 2.03 no shared subfolder is created at acl/subscription set time so subscribing afterwards fail with ignore message by bad subscription the mails store is on drbd with ocfs2 i didnt change any other config parameter during the tests so some patch must have changed folder sharing behavior from 2.03 to 2.04 speculate something with default hardlinks etc? any idea ? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] ACL handling bugs in v1.2.8+ and v2.0
by Timo Sirainen 02 Oct '10

02 Oct '10

I thought I'd write one mail about this, rather than duplicate the whole thing to both v1.2.15 and v2.0.5 release announcements. So, ever since this commit: 2009-11-10 Timo Sirainen <tss(a)iki.fi> * src/plugins/acl/acl-backend-vfile.c: acl: Merge group rights if user belongs to more than one. [76ff6831c9ae] The ACLs were being merged, rather than fully replaced, a bit too often. Since this is about merging, the problem could have happened only when using more than one entry in the ACL file. The main problems created by this were: a) If admin wanted to remove some rights from mailboxes in user's private namespace (e.g. symlinked shared mailboxes), they may not have gotten removed. b) When mixing up multiple ACL entries, such as groups/users the more specific entry may not have replaced the previous entry (e.g. group-override may not have worked as expected). The bug happened when two or more ACL entries of same "type" existed. The first entry was handled correctly, but the next ones may have only been adding ACLs rather than replacing them. For example if you had the following ACL file: group=people lrwi user=foo lr user=bar lr So basically everyone in "people" group should have "lrwi" rights, but foo and bar users should have only "lr" rights. If foo and bar didn't belong to people group, everything would work as expected. If they did, then what would happen is: * foo would work correctly, because it was the first entry of user type. * bar would keep "lrwi" rights, because the previous entry (user=foo) was of the same type (both are "user" type), so Dovecot decided to add the rights on top of group=people entry rather than replace them. BTW. The other ACL bug/"feature" of automatically adding admin rights that was fixed in v1.2.15 was already fixed in v2.0.beta2.

[Dovecot] IMAP connection timeout value?
by Tamas Kadar 01 Oct '10

01 Oct '10

So we're having some ISP issues lately, meaning we have to reboot our cable modem like 2-3 times a day. An unfortunate side-effect I've found is, once the users max out their connection limit (which I've set to 10, and many people do), if we reboot the cable modem, they can't log in cause their connections get 'stuck' until I `doveadm kick` them, or wait for the connections to timeout which takes ??? minutes. Can I adjust that value to something like 30 seconds? Thanks and best regards, KT

[Dovecot] SSL strangeness with dovecot-lda in 2.0.4

Hello, First of all, thank you for developing a fantastic IMAP server! I've just upgraded to 2.0.4 (from 2.0.1) and when I try to run /usr/lib/dovecot/deliver (either directly from the commandline, or from within the MTA) I get the following error: doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: ssl enabled, but ssl_key not set I converted my old config file settings using "dovecot -c /etc/dovecot/dovecot.orig -n > /etc/dovecot/dovecot.conf" as some of the option names had changed. The computer has been rebooted since the upgrade.

[Dovecot] Possible bug with proxy in 2.0.4
by Ed W 01 Oct '10

01 Oct '10

Hi, I *think* there might be an auth/proxy bug in 2.0.4 Specifically I cloned my 1.2 virtual machine, upgraded the clone to 2.0.4 and tested it by trying to login using CRAM-MD5. I get the errors: Sep 29 22:50:23 mail_test dovecot: imap-login: Disconnected (auth failed, 1 attempts): user=<demo(a)abc.com>, method=CRAM-MD5, rip=x.x.x.x, lip=x.x.x.x, mpid=0, TLS Sep 29 22:50:30 mail_test dovecot: auth: mysql: Connected to mysql-local (postfix) Sep 29 22:50:30 mail_test dovecot: imap-login: Error: proxy: password not given: user=<demo(a)abc.com>, method=CRAM-MD5, rip=x.x.x.x, lip=x.x.x.x, mpid=0, TLS Interestingly the config here (accidently as it happens) causes the connection to use the dovecot "proxy" feature back to the original 1.2 machine. I updated my config so that everything stays on the 2.0.4 machine and authentication proceeds normally, messages about generating MD5 hash from the DB, etc, logged in ok. I then change the configuration so that the 2.0.4 machine proxies the connection back to the 1.2 machine (again) and try to login to the 2.0.4 machine and get the same errors as above. Seems like the error is only when proxying (needless to say, the old 1.2 machine works fine with CRAM and that's how it's normally accessed, so also does the 2.0.4 machine, it's only proxying one to the other which isn't apparently working?) It's late and so I haven't managed to probe the 1.2 machine too much, but initially looking at the log files I don't see any evidence of the 2.0.4 machine actually contacting it? Does this make sense? Thanks Ed W

[Dovecot] v1 ok, v2 not
by Alberto 01 Oct '10

01 Oct '10

hello everybody! This's my very first post in dovecot. I'm installing a new server for backup site, with qmail + vpopmail 5.4.32 + dovecot. Production server, more or less outdated, runs with Couier Imap, but everybody know the history.. I've been fighting for several days...And no luck with version 2.0.4, 2.0.3 neither. My first asumption was to review things thousand of times due to newbie condition... This morning I've tried version 1.2.14 and voila! , it works perfectly! The error log with version 2 was the famous unkown user one: dovecot: auth: vpopmail(test4(a)adomain.com,10.206.16.10): unknown user test4 user worked perfectly with pop3... Just FYI, is this can help. Regards!

[Dovecot] How does sieve's vacation keep track of duplicates?
by ben＠electricembers.net 01 Oct '10

01 Oct '10

I see the .dovecot.lda-dupes file that is created, but it doesn't seem like just plain text, and it doesn't seem to include strings of the senders, just the recipient. But I know the vacation functionality is clever enough to keep track of who it's already autoreplied to. On a related note, I'm curious about other smarts built in to sieve's vacation responder -- what other things does it check, like Precedence header? Benjamin

[Dovecot] Vacation script execution question.
by Lauro Costa G. Borges 30 Sep '10

30 Sep '10

dovecot 1.2.9 --- I wanna know how the vacation script works. I don't understand why it tries to find locally (using LDAP) a recipient for the "vacation notification email". On the log, "sender_email(a)gmail.com" is the person sending email to "lauro(a)my.domain.org", which is on vacation. Deliver tries to find locally "sender_email(a)gmail.com", to send the vacation notification message: ---- imap dovecot: deliver(lauro(a)my.domain.org): sieve: msgid=<AANLkTim2HNbM=7WNoMOySg3UXgrikGnVdXR+wjhOG7(a)mail.gmail.com>: sent vacation response to <sender_email(a)gmail.com> imap dovecot: deliver(lauro(a)my.domain.org): Namespace : Using permissions from /var/mail/mailboxes/my.domain.org/lauro~my.domain.org: mode=0700 gid=-1 imap postfix/cleanup[21083]: 3E01140A59: message-id=<dovecot-sieve-1285855441-226458-0@imap> imap postfix/qmgr[21051]: 3E01140A59: from=<>, size=615, nrcpt=1 (queue active) imap postfix/trivial-rewrite[21082]: dict_ldap_debug: ldap_build_search_req ATTRS: associatedDomain imap postfix/local[21089]: warning: dict_ldap_open: /etc/postfix/ldap-domain-maps.cf: Fixed query_filter (objectclass=domainRelatedObject) is probably useless imap postfix/pipe[21090]: warning: dict_ldap_open: /etc/postfix/ldap-domain-maps.cf: Fixed query_filter (objectclass=domainRelatedObject) is probably useless imap dovecot: deliver(sender_email(a)gmail.com): Loading modules from directory: /usr/lib/dovecot/modules/lda imap dovecot: deliver(sender_email(a)gmail.com): Module loaded: /usr/lib/dovecot/modules/lda/lib10_quota_plugin.so imap dovecot: deliver(sender_email(a)gmail.com): Module loaded: /usr/lib/dovecot/modules/lda/lib90_sieve_plugin.so imap dovecot: auth(default): master in: USER#0111#011sender_email(a)gmail.com#011service=deliver imap dovecot: auth(default): prefetch(sender_email(a)gmail.com): passdb didn't return userdb entries, trying the next userdb imap dovecot: auth(default): ldap(sender_email(a)gmail.com): user search: base=ou=gmail.com,ou=mail,ou=services,dc=ufsc,dc=br scope=subtree filter=(& (cn=sender_email)(objectclass=nisMailAlias)(ContaAtiva=TRUE) ) fields=rfc822MailMember,EmailQuota,EmailQuotaSpecial,eduPersonPrincipalName imap dovecot: auth(default): ldap(sender_email(a)gmail.com): ldap_search((& (cn=sender_email)(objectclass=nisMailAlias)(ContaAtiva=TRUE) )) failed: No such object : Why is that? ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

[Dovecot] dovecot-lda segfaults with some sieve scripts
by interfaSys sàrl 30 Sep '10

30 Sep '10

Hello, One account couldn't get emails all the sudden. dovecot-lda was crashing with "signal 11 (segmentation fault)". There was absolutely nothing in the dovecot logs, even with mail_debug=yes. I found out that it was because of the following lines in a sieve script that were generated by a script generator (Ingo). if true { keep; stop; } I'm using the latest revision of pigeonhole with Dovecot 2.0.4. Cheers, Olivier

[Dovecot] Fwd: NFS question
by Nick Edwards 30 Sep '10

30 Sep '10

Resent to list, since my previous direct emails to Timo have gone unanswered I am NOT a member of this list so Timo please reply direct I do not wish responses from those who are not developers of dovecot, many I have since had discussions with on another list and spam binned (abusive souls like charlie marcus) some for trolling, I seek a definitive answer and there is only one man who can give this, but I likely was mailing a old address he doesn't read ---------- Forwarded message ---------- From: Nick Edwards <nick.z.edwards(a)gmail.com> Date: Fri, Sep 24, 2010 at 6:15 PM Subject: NFS question To: timo(a)iki.fi After reading the archives recently on a few threads about NFS I have concerns over our plans to move from cyrus to dovecot, we initially discounted dovecot as a choice over it, but since dovecot and sieve go well together, I am just re-capping everything before we approve move to courier or back to dovecot, having re read those threads over a couple of times, am I right in assuming that this caching problem, is really only a problem if using imap and the chances of it being an issue with pop3 is very rare? If this is the case, then we certainly would approve move to dovecot. I note some people who have apparently much larger systems than us, say that they have seen no problems but others say they may have had just not noticed. So, if smtp3 delivers to storage MailDir and pop3-1 connects to get mail - at the same time: no problem just wont see that message until next refresh at the same time: will see message if smtp3 and smtp1 deliver at same time there lies the corruption issue? If so, it will be reindexed at next delivery or pop3? Just trying to understand where it will be a problem, we will use postfix setting of virtual_transport = dovecot and dovecot_destination_recipient_limit = 1 We dont allow multiple logins either, we have only intention for one imap server, to compliment our two pop3's and 4 smtp's. We intend to use - pop3_lock_session=yes maildir_very_dirty_syncs=yes auth_verbose = yes auth_cache_size = 512 auth_cache_ttl = 3600 auth_cache_negative_ttl = 0 mail_location = maildir:/var/vmail/%1d/%d/%n/Maildir mmap_disable = yes mail_nfs_storage = yes mail_nfs_index = yes protocol lda { mail_plugins = quota cmusieve quota_full_tempfail = yes auth_socket_path = /var/run/dovecot/auth-master } Also, will this be more of a problem if we use dovecot v1.2 or v2.0 ? (only examples of configs we have for our move is for v1.2 at present for debian) Hope you do not mind me asking this in private, but given how those threads ended up in personal attacks, I would rather not reignite any fires.

hi, I see in dovecots logfile some error messages: Sep 29 15:33:43 auth(default): Error: LDAP: Connection lost to LDAP server, reconnecting Sep 29 15:34:15 auth(default): Error: LDAP: Connection lost to LDAP server, reconnecting Sep 29 15:34:50 auth(default): Error: LDAP: Connection lost to LDAP server, reconnecting Sep 29 15:35:22 auth(default): Error: LDAP: Connection lost to LDAP server, reconnecting Sep 29 15:36:01 auth(default): Error: LDAP: Connection lost to LDAP server, reconnecting Sep 29 15:36:37 auth(default): Error: LDAP: Connection lost to LDAP server, reconnecting Sep 29 15:37:16 auth(default): Error: LDAP: Connection lost to LDAP server, reconnecting Sep 29 15:37:52 auth(default): Error: LDAP: Connection lost to LDAP server, reconnecting Sep 29 15:38:24 auth(default): Error: LDAP: Connection lost to LDAP server, reconnecting I don't know, what could be the problem. I upgraded Dovecot from 1.2.13 to 1.2.14 to solving the problem, but ... no success. Our LDAP Server is 2.4.23 and works for our network without any problems. If I try to use ldapsearch from the Dovecot host, while I see the messages, ldapsearch works withouch any timeout. I enabled caching for auth too, but the problem still exists. My DoveCot Config: http://pastebin.com/W7zHf4fT the LDAP part: hosts = ldap ldap2 auth_bind = yes ldap_version = 3 base = cn=accounts, dc=foo user_attrs = postalAddress=domain, homeDirectory=/imap/spool/%d/%1n/%n, myMailQuota=quota_rule=*:storage=%$M user_filter = (&(objectClass=posixAccount)(uid=%n)) pass_attrs = postalAddress=domain, uid=user, userPassword=password pass_filter = (&(objectClass=posixAccount)(uid=%n)) default_pass_scheme = MD5 any suggestions? cu denny ps. when does dovecot switches to ldap2?

[Dovecot] Can we retrieve Dovecot Proxys 'hostName' from Director instead of LDAP?
by Edward Carraro 30 Sep '10

30 Sep '10

We have a Dovecot installation of several nodes that share an NFS mount for the user data. We are trying to configure Dovecot Proxy with Director in order to have Director select the appropriate IMAP server for a given user on behave of Dovecot Proxy. So far all examples I've seen on the dovecot site require the proxy to know the exact mail server to pass the user to by way of an LDAP lookup. Does anyone know of a way to have Dovecot Proxy pick a server from Directors status list instead of looking it up from LDAP? Also, how does Director discover that an IMAP server is up or down so that it can adjust in the case of a server failure? Is this something that Director does automatically or do we need to manually change the mail servers vhost count in case of an IMAP node failure? Thanks

[Dovecot] Problem with dovecot-acl
by dss 30 Sep '10

30 Sep '10

I have a problem with dovecot-acl. Some of our users need to use the same Mailbox with all folders: Inbox (with subfolders), Outbox, Send and Deleted, (some users need in full righs, some - readonly) so I choosed Symlinking mailboxes and tried to use dovecot-acl file. cat dovecot-acl: user=t1 lrwsti user=operolegs lrwsti user=operantona lrwsti user=operdss lr User operdss have lrwsti rights in this shared mailbox unstead of lr! But if I comment out other users in the dovecot-acl: #user=t1 lrwsti #user=operolegs lrwsti #user=operantona lrwsti user=operdss lr User operdss have lr rights. Whats wrong?

If you assume the user retrieves their mail soon after delivery, it doesn't make sense. :) I think the biggest benefit to my service is the catching is phisjing scams aimed at my users. I usually get a copy (dolts), and I will block the reply to addresses, but it would be better to remove it cpmpletely. Another possible use might be URL scanning for updated malware sites and labeling it accordingly -but modifying an email might a little excessive for this function. Rick

[Dovecot] Sieve during read or login?
by Rick Romero 29 Sep '10

29 Sep '10

I was wondering if anyone thought of applying filters to email post delivery, pre-read. Basically the idea would be to head off Spam, Malware or Phishing for already delivered email. Malware would probably be the least likely target, as (knock on wood) user workstations would be updated, but a targeted phishing scam would not create a public signature that would be downloaded, yet an admin may have a regex that could be used to remove that email before it left the server. I used to run find and grep on my Maildirs, but that's no longer practical. I think maybe an 'on connect', or 'on read' might be an option. Thoughts? Rick

[Dovecot] Doubts with email copying
by Alex Baule 28 Sep '10

28 Sep '10

Hi Timo..... Trying to resolve my problem with the references in copying a email between Folders (when i move from inbox -> sent for example), i got some doubt. My plugin create a new ostream in v->save_begin, and i start a function from my library to create the reference, but when the email is been copying, the new email don't pass in this function, and i don't start my function to create a reference. My doubt is, if copying a email is a "copy + paste", why the s->save_begin it's not called ? I search in the iostream-internal.h to rewrite some "open stream" but the only one available is the close. There is a place to call my function every time that one ostream is opened, including the copy ?

[Dovecot] v2.0.4 released
by Timo Sirainen 28 Sep '10

28 Sep '10

http://dovecot.org/releases/2.0/dovecot-2.0.4.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.4.tar.gz.sig multi-dbox users: Be careful about the INDEX change. Maildir users: I hope v2.0 is now finally stable. * multi-dbox: If :INDEX=path is specified, keep storage/dovecot.map.index* files also in the index path rather than in the main storage directory. WARNING: if you specified :INDEX= with earlier mdbox installation, you must now manually move the storage indexes to the expected directory! Otherwise Dovecot won't see them and will rebuild the indexes, possibly unexpunging some mails. - Maildir: Copying messages with hard links sometimes caused the source maildir's entire tmp/ directory to be renamed to destination maildir as if it were a message. - Maildir: v2.0.3 broke expunging copied messages sometimes - Maildir: INBOX whose tmp/ directory was lost couldn't be opened - single-dbox: Messages weren't copied with hard links - vpopmail support is hopefully working again. - dsync: POP3 UIDLs weren't copied with Maildir - dict file: Fixed fd leak (showed up easily with LMTP + quota)
