[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?

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.

[Dovecot] pop3-login no longer segfaults with gcc4.5.2 and gold :)

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

[Dovecot] migration 1.2.5 -> 2.0.5 load increased dramatically
by Ralf Hildebrandt 06 Oct '10

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

Hello all, First of all sorry for this, it has been discussed many times, but i can not make it work. I tried for a long time now. I do something wrong, but i do not know what. 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

[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? Something missing/incorrect? Thanks!

[Dovecot] Can't receive emails
by Chris 05 Oct '10

05 Oct '10

Hello everyone, I installed postfix and dovecot (imap + pop) on a debian server. I can send emails via postfix and I could receive emails via dovecot before. Yesterday my server got shutdown and restarted and since then, I somehow have some problems. If I send some emails, I don't receive them in /var/vmail/%d/%n/Maildir But the login works fine (pop and imap). How can I figure out, why there are no mails comming?

[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] Virtual Folders
by qmail＠top-consulting.net 05 Oct '10

05 Oct '10

I have the following setup: dovecot --version 1.2.10 namespace private { prefix = virtual. separator = . location = virtual:~/Maildir/virtual:INDEX=MEMORY } protocol imap { mail_plugins = quota imap_quota fts fts_solr antispam virtual #pwd ~/Maildir/virtual/all #cat dovecot-virtual * all The problem is that I can't access any of the virtual folders. Logging the IMAP conversation showed me this: 5ptq SELECT "virtual.all" frdv IDLE 5ptq NO Mailbox doesn't exist: all (all)^M + idling^M frdv OK Idle completed.^M What am I doing wrong ?

[Dovecot] question on quota configuration on 2.0.5
by Leonardo Rodrigues 05 Oct '10

05 Oct '10

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.
