[Dovecot] patch for 2.0.alpha3 crash

Dovecot-2.0.alpha3 crashes on startup for me on Mac OS X.

[Dovecot] selective disable_plaintext_auth
by Mariano Absatz 11 Nov '09

11 Nov '09

Hi, I've been using dovecot for some time now, always with the setting: disable_plaintext_auth = yes so that no user can accidentally expose their username/password in the open. However, I'm now trying to configure a webmail client in a nearby server which doesn't support TLS or SSL IMAP connections :-( Is there any way to allow plaintext_auth only for a small set of IP addresses (for what I see in the comment, this is automatic for local addresses, alas, the webmail client is on another host).

Hi All, Sorry if this is a dumb questions, but what methods are available for retrieving mail for a system user i.e www-data. Basically my setup is just a normal Dovecot-IMAP which is working fine for shell users, but I want to be able to read mail for system users via IMAP. Is this doable? Cheers

[Dovecot] Missing 'mailbox' variable ?
by David Goncalves 10 Nov '09

10 Nov '09

Hi, I'm using Dovecot with LDAP. My users have an home directory and a field named 'mailMessageStore'. Then the full mailbox path is 'homeDirectory/mailMessageStore' In dovecot-ldap.conf i configured as follows : user_filter = (&(objectClass=qmailUser)(cn=%u)) user_attrs = qmailUID=uid,qmailGID=gid,homeDirectory=home,mailMessageStore=mail=maildir:~/%$ Everything is working as expected but... I'm using sieve and in the 'dovecot.conf' there is no way to get a variable containing the mailbox path... As the mailMessageStore field can contain something different than the login or uid, how can i get the mailbox path in the conf ? Regards. -- David Goncalves - http://www.lestat.st

[Dovecot] Auth failure delays
by Timo Sirainen 09 Nov '09

09 Nov '09

Currently Dovecot works like this when authentication fails: - the delay is always at least auth_failure_delay seconds (default: 2s) - each failed attempt doubles the delay for that specific imap/pop3 connection (no such delays for e.g. smtp) - the delay's upper limit is 3 minutes For v2.0 I was planning on making dovecot-auth process do these checks and keeping the state in anvil process: - the delay is always at least auth_failure_delay seconds (default: 2s) - for each remote IP address the delay is doubled, regardless of how the request comes (imap, pop3, smtp, etc). - the delay's upper limit is .. hardcoded to 15 secs? i kind of hate the thought of making this configurable. - each successful authentication from the IP resets the IP's delay - the delay happens before authentication is even attempted, so even successful auth attempts will have the delay (unless of course there haven't been auth failures from that IP) If the upper limit is 15 secs, that means max. 240 auth attempts per hour per IP. The reason I was thinking 15 secs is because I have some vague memories about Thunderbird dropping connection after 15 or maybe 30 seconds of idling. If user has one successful login, it's of course possible to get around the delay doubling by just doing failed attempt -> successful attempt -> failed -> success -> etc. But probably no one is really going to try to do that, and even if they did it's still not that bad. The second successful login will still have that 2 second delay before it resets the delay. So that's still max one auth/2 seconds or max. 1800 auth attempts/hour. Any thoughts?

In fact, because multiple uids (and gids) have to create a directory there, you have to use a tmp-like directory. "1xxx" means the sticky-bit, so users may not remove an entry owned by another user. Because root is owner of /var/dvindex, you have just those two users able to remove: root and the owning user of the subdir. The user-specific subdirectories should be 0700 or something like that, so the security is OK.

IMHO, as soon as you have system users the /var/dcindex must be 1777, the few exceptions, when all users share a single group, or you can pre-create the directories are the special cases. BTW: _If_ you use system users and your account name <-> uid relationship can change, you should use an template different than /var/dcindex/%u, e.g. /var/dcindex/%i, because if a new user with an name already used in past, but with another uid logs on the server, the uid cannot access the old /var/dcindex/ahinds tree. The leftover files should not make much worries, except the subscription perhaps.

[Dovecot] v2.0 lmtp logging
by Pascal Volk 05 Nov '09

05 Nov '09

Hi, I am not yet completely happy with the logging behavior of the lmtp. It logs informative messages like 'lmtp: Info: Connection closed' or 'lmtp: Info: Disconnected for inactivity'. Hm, which server was connected to the lmtp? Who was disconnected for inactivity? I think it would be useful if the lmtp would also log new connections. For example: a) TCP connections: lmtp: Info: Connection: rip=10.1.2.3, lip=10.1.2.5, cid=1255555555.12345 b) Socket connections: lmtp: Info: Connection: via socket, cid=1255555777.10452 rip: There may be multiple SMTP servers in front the IMAP server(s) lip: The lmpt may listen to more than one address cid: The 'connection ID', consists of the current unix time and the pid of the lmtp process. (Or some other values in some other format) The cid should be used in the 'saved' messages. So the delivering MTA would see something like '250 2.0.0 OK: 1255555555.12345 Saved', instead of a message like '250 2.0.0 <jdoe(a)example.com> Saved'. The lmtp should also write the cid to the log. For example: 'lmtp(jdoe): Info: msgid=123, cid=1255555555.12345: saved mail to INBOX' (or discarded because of a matching sieve rule). With this connection ID it would be possible to trace the route which the e-mail has taken. Regards, Pascal -- The trapper recommends today: c01dcafe.0929623(a)localdomain.org

[Dovecot] meaning of parameter imap_idle_notify_interval??
by Ingo Thierack 05 Nov '09

05 Nov '09

Hello, is my understanding of the parameter "imap_idle_notify_interval" right, if i say, it's the time between two point where dovecot tells the client he is here, and sould have nothing directly todo with the notification of new mails arrived. I played with the values around. And the courios is, in thunderbird the folloing. set to 30 seconds. Thunderbird pop up around 25 seconds after the message is deliverd to the inbox. set to 60 seconds. Thunderbird pup up around 50 seconds after the message is deliverd to the inbox. I switch over from archiveopteryx, where no such delay was. Regards, Ingo

[Dovecot] defunct in 1.24 on FreeBSD Alphaserver
by Paweł Kaczor 05 Nov '09

05 Nov '09

Hello, I've recently upgraded Dovecot from 1.1.16 to 1.2.4 on FreeSBD 6.3- RELEASE running on old Alphaserver 1200. Some time after this upgrade all user's MUAs showed error that user password was not accepted. I've noticed many zombies of imap and pop3 processes on my server (all in defunct state). Looks like when "login_max_processes_count" was reached, Dovecot canceled all new connections. I've setup completely new configuration based on http://wiki.dovecot.org/TestInstallation and no error was produced but every time I closed telnet the imap process became defunct. So, I tried to trace what was happening with ktrace: ktrace -d -f log -p pid_of_imap_process In attached file is a part of ktrace output at the moment when I close telnet connection. What is interesting (at last for me, but I'm lamer) is an error: 1576 imap 1256902587.568406 CALL close(0xffffffffffffffff) 1576 imap 1256902587.568448 RET close -1 errno 9 Bad file descriptor AFAIK, such error could be produced by inconsistent file system so I double checked OS and I'm 100% sure it's OK. At the very end of this history I had to switch back to 1.1.16 version of Dovecot which works OK now. I'll be very thankful if somebody could point me to explanation what can cause such strange behavior. Regards, Pawel Kaczor -- "A z kwiatków, jakie pan lubi najbardziej?

[Dovecot] IMAP goes down from time to time
by Juan Felipe Estrada 05 Nov '09

05 Nov '09

Good Morning I´m writing back cause the IMAP going down issue has changed a little, i still have the dovecot-1.0.7-7.el5 but with 2 changes; I added to the dovecot.conf the outlook-idle workaround, and the three login_processes parameters login_process_per_connection = yes login_processes_count = 3 login_max_processes_count = 128 Since I added this parameters the IMAP process has gone down just 1 time in 2 weeks, before this, the proccess was going down about 4 times a day so I think this is suitable, the next step i´ll take is to update the Dovecot.

[Dovecot] Post login script issue with pop3 protocol

My script: ---- LDAP_URI='ldap://127.0.0.1:389' LDAP_BASEDN='o=domains,dc=iredmail,dc=org' BIND_DN='cn=vmailadmin,dc=iredmail,dc=org' BIND_PW='plain_passwd' if [ X"${USER}" != X"dump-capability" ]; then ldapmodify -c -x \ -H "${LDAP_URI}" \ -D "${BIND_DN}" \ -w "${BIND_PW}" <<EOF dn: mail=${USER},ou=Users,domainName=$(echo ${USER} | awk -F'@' '{print $2}'),${LDAP_BASEDN} changetype: modify replace: lastLoginDate lastLoginDate: $(date +%Y%m%d%H%M%SZ) - replace: lastLoginIP lastLoginIP: ${IP} - replace: lastLoginProtocol lastLoginProtocol: pop3 EOF fi ---- It works with IMAP protocol, but failed with POP3 protocol.

[Dovecot] Why : dovecot_destination_recipient_limit = 1 ?
by Koenraad Lelong 03 Nov '09

03 Nov '09

Hi all, I'm trying to activate sieve. In all tutorials I have seen I need to set dovecot_destination_recipient_limit = 1 in Postfix's main.cf. Can anyone explain why ? I like to know because when I set this and the dovecot transport in Postfix, I'm having problems when aliasses are used that map to different recipients, i.e. info@... results in user1@..., user2@..., etc. The problems are an error from Postfix : Oct 30 09:25:19 lace3 postfix/pipe[19729]: 8A77E2D5B5B: to=<some.body(a)some.where.org>, relay=dovecot, delay=2390, delays=2390/0.04/0/0.01, dsn=4.3.5, status=deferred (mail system configuration error) Oct 30 09:25:19 lace3 postfix/pipe[19729]: warning: pipe flag `D' requires dovecot_destination_recipient_limit = 1 Thanks for any info. Regards, Koenraad Lelong.

[Dovecot] X.509 certificate based IMAP login
by dovecotlist＠encambio.com 03 Nov '09

03 Nov '09

Hello list, The dovecot version is 1.2.6 running on Solaris x86 11 (nv-b91). The relevant configuration lines are: passdb ldap { # LDAP database (doc/wiki/AuthDatabase.LDAP.txt.) args = /pfx/etc/dovecot/dovecot-ldap.conf } The file dovecot-ldap.conf is correct and LDAP authentication is working well. We would like to make it possible for users with a X.509 client certificate to log in without providing LDAP or any other credentials. Is there something like: passdb x509 { args = /pfx/etc/dovecot/dovecot-caroots.pem nopwd = yes } ...avaibable, or is there another solution? Thanks, Brian

[Dovecot] second fs quota root crashes

Hallo. In our dovecot 1.2.6 server running under Solaris 9 I would like to set up a second quota root because the mail folders are in the users home directories and the inboxes of all users are in /var/mail. As soon as I add quota2 = fs:INBOX:noenforcing:mount=/var/mail the imap client crashes repeatedly as soon as the user tries to open a mail folder. Thanks for any help.

03 Nov '09

Just saw this new twist to an issue I reported last week with dovecot-2.0.alpha2. I logged into an IMAP account using telnet to port 143. After 30 seconds dovecot closed the connection. Mon Nov 2 16:00:07 server dovecot[52355]: imap: dup2(-1, 5) failed: Bad file descriptor Mon Nov 2 16:00:07 server dovecot[52355]: imap: service(imap): dup2s failed Mon Nov 2 16:00:07 server dovecot[52355]: imap-login: Login: user=<userV>, method=PLAIN, rip=192.168.1.10, lip=192.168.1.7, pid=59521 Mon Nov 2 16:00:37 server dovecot[52353]: master: service(imap): Initial status notification not received in 30 seconds, killing the process Mon Nov 2 16:00:37 server dovecot[52353]: master: service(imap): child 59521 killed with signal 9 Mon Nov 2 16:00:37 server dovecot[52353]: master: service(imap): command startup failed, throttling

[Dovecot] Unable to create imap nested dirs.

Hi all, I'm trying to config a dovecot server on a debian-lenny box but I'm experiencing a problem that serveral users have on the net, but I haven't found any solution. I'm trying to create nested dirs with my thunderbird 2.0.0.23 client but without any luck :( I can create dir in the root, but not subdirs. have you any ideas? here you can you see the small config and attached my full config dovecot -n # 1.2.4: /etc/dovecot/dovecot.conf # OS: Linux 2.6.12.6-arm1 armv5tejl Debian 5.0.3 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mbox_write_locks: fcntl dotlock auth default: passdb: driver: pam userdb: driver: passwd # dovecot -a # 1.2.4: /etc/dovecot/dovecot.conf # OS: Linux 2.6.12.6-arm1 armv5tejl Debian 5.0.3 base_dir: /var/run/dovecot log_path: info_log_path: log_timestamp: %Y-%m-%d %H:%M:%S syslog_facility: mail protocols: imaps listen: * ssl_listen: ssl: yes ssl_ca_file: ssl_cert_file: /etc/ssl/certs/dovecot.pem ssl_key_file: /etc/ssl/private/dovecot.pem ssl_key_password: ssl_parameters_regenerate: 168 ssl_cipher_list: ssl_cert_username_field: commonName ssl_verify_client_cert: no disable_plaintext_auth: yes verbose_ssl: no shutdown_clients: yes nfs_check: yes version_ignore: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_user: dovecot login_greeting: Dovecot ready. login_log_format_elements: user=<%u> method=%m rip=%r lip=%l %c login_log_format: %$: %s login_process_per_connection: yes login_chroot: yes login_trusted_networks: login_process_size: 64 login_processes_count: 3 login_max_processes_count: 128 login_max_connections: 256 valid_chroot_dirs: mail_chroot: max_mail_processes: 512 mail_max_userip_connections: 10 verbose_proctitle: no first_valid_uid: 500 last_valid_uid: 0 first_valid_gid: 1 last_valid_gid: 0 mail_access_groups: mail_privileged_group: mail mail_uid: mail_gid: mail_location: mail_cache_fields: mail_never_cache_fields: imap.envelope mail_cache_min_mail_count: 0 mailbox_idle_check_interval: 30 mail_debug: no mail_full_filesystem_access: no mail_max_keyword_length: 50 mail_save_crlf: no mmap_disable: no dotlock_use_excl: yes fsync_disable: no mail_nfs_storage: no mail_nfs_index: no mailbox_list_index_disable: yes lock_method: fcntl maildir_stat_dirs: no maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: no maildir_very_dirty_syncs: no mbox_read_locks: fcntl mbox_write_locks: fcntl dotlock mbox_lock_timeout: 300 mbox_dotlock_change_timeout: 120 mbox_min_index_size: 0 mbox_dirty_syncs: yes mbox_very_dirty_syncs: no mbox_lazy_writes: yes dbox_rotate_size: 2048 dbox_rotate_min_size: 16 dbox_rotate_days: 1 mail_drop_priv_before_exec: no mail_executable: /usr/lib/dovecot/imap mail_process_size: 256 mail_plugins: mail_plugin_dir: /usr/lib/dovecot/modules/imap mail_log_prefix: %Us(%u): mail_log_max_lines_per_sec: 10 imap_max_line_length: 65536 imap_capability: imap_client_workarounds: imap_logout_format: bytes=%i/%o imap_id_send: imap_id_log: imap_idle_notify_interval: 120 pop3_no_flag_updates: no pop3_enable_last: no pop3_reuse_xuidl: no pop3_lock_session: no pop3_uidl_format: %08Xu%08Xv pop3_client_workarounds: pop3_logout_format: top=%t/%p, retr=%r/%b, del=%d/%m, size=%s dict_db_config: dict_process_count: 1 managesieve_max_line_length: 65536 managesieve_logout_format: bytes=%i/%o managesieve_implementation_string: dovecot auth default: mechanisms: plain realms: default_realm: cache_size: 0 cache_ttl: 3600 cache_negative_ttl: 3600 executable: /usr/lib/dovecot/dovecot-auth user: root chroot: username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ username_translation: username_format: master_user_separator: anonymous_username: anonymous krb5_keytab: gssapi_hostname: winbind_helper_path: /usr/bin/ntlm_auth failure_delay: 2 verbose: no debug: no debug_passwords: no ssl_require_client_cert: no ssl_username_from_cert: no use_winbind: no count: 1 worker_max_count: 30 process_size: 256 passdb: driver: pam args: deny: no pass: no master: no userdb: driver: passwd args:

[Dovecot] Author wanted for Dovecot article in Linux Magazine (Germany)
by Markus Feilner 31 Oct '09

31 Oct '09

Hi list, I am an editor at the German Linux Magazine and I am searching for an author or input on Dovecot, its advantages and especially the recent features. I had organized some authors, but unfortunately they don't have time right now. :-) Nevertheless I heard many positive comments on Dovecot. I can write or help writing the article, but I would love to have some input from an experienced dovecot admin - perhaps with some stunning, unusual setup that might interest our readers (most of them are skilled admins and programmers...) Something that can't be easily done with other mail servers would be great, something spectacular that is suitable to convince an mail admin why he should migrate to Dovecot. It won't be long, just about 2-3 pages (a maximum of 15000 characters) including screen shots and/or listings, code, > 10 Links and an author's biography with photo. Anybody interested? That would be great, feel free to send me a mail to: mfeilner(a)linuxnewmedia.de Unfortunately, we don't have much time, there's only two weeks left, but I will help and do a lot of work for the article. And don't worry about language! :-) Thanks a lot! -- Best Regards - Mit freundlichen Gruessen Markus Feilner ------------------------- Feilner IT Linux & GIS Linux Solutions, Training, Seminare und Workshops - auch Inhouse Koetztingerstr 6c 93057 Regensburg Telefon: +49 941 8 10 79 89 Mobil: +49 170 3 02 70 92 WWW: www.feilner-it.net mail: mfeilner(a)feilner-it.net Bei Xing: http://www.xing.com/profile/Markus_Feilner -------------------------------------- My OpenVPN book - OPENVPN : Building and Integrating Virtual Private Networks http://www.packtpub.com/openvpn/book My new book - Out now: SCALIX Linux Administrator's Guide http://www.packtpub.com/scalix/book

[Dovecot] Dovecot in-house benchmarking
by Joseba Torre 30 Oct '09

30 Oct '09

Hi, Before some major changes in our infrastructure, I was interested in the performance impact of moving indexes to our NAS (Emc Celerra v5.5). So I downloaded both dovecot-1.1.19 and dovecot-1.2.6, compiled them and wrote 2 confs for each of them, one with local indexes and another with indexes in the NAS. Then I created 19 pam users, and tested system performance this way: - uninstall current installed version - install a new version - start dovecot - for each user run: imaptest user=user pass=pass host=localhost port=143 mbox=${MBOX} seed=123 secs=300 | tail -1 > file - stop dovecot I'm not sure if these tests are real, but our results are: * In our conf, 1.1.19 and 1.2.6 performance are roughly the same * Moving the indexes to our NAS makes the system 3 times slower As we currently only have 1 system accessing mails or indexes, I tried later with nfs_* = no, and mmap_disable = no. This makes performance 10% better in any situation. Our testing setup (very close to the real one) - Dell PowerEdge 2850, 2 P4 Xeon 3GHz, 3GB RAM - RHEL 4.7 (not sure about this, the last RHEL4) 32 bits - mailboxes are always in a nfs filesystem - for testing mbox file I've used dovecot-cvs.mbox I've attached a couple of graphs to show this results (I've a lot of them, but result are pretty close from one to another). Also, dovecot -n output for 1.2.6 with indexes in the NAS. Only needed changes have been applied from one conf to another. If you feel that the benchmark can be more "real" with some changes, just tell me. Also, if you are interested in the rest of graphs or date, tell me. Next week I'll be quite busy, but as soon as possible I'll test with an iSCSI disk for indexes. Aaaaaaaaaaagur. -- Joseba Torre. Vicegerencia de TICs, área de Explotación

[Dovecot] How to see if sieve is active ?
by Koenraad Lelong 30 Oct '09

30 Oct '09

Hi, I think I activated sieve, but it's doing nothing. I know manage-sieve works so I made some rules. But they do nothing. I ran sieve-test, which seems to work, but does not move the mail I test. Is this how it works ? I thought the -e parameter just "tested" the rules and did nothing and my command was supposed to do the "real thing". I read there should be a log. I don't find this, how should I enable this ? I just found that lda can have a separate log. I'll enable this and see. I read the wiki-page different times, but I don't see what I'm doing wrong. I attached some files. Sieve-test.txt is the command and output from sieve-test. Phpscript.sieve is the file .dovecot.sieve points to, and dovecot-config is my dovecot config ;-). Thanks for any pointers.

[Dovecot] dovecot-shared and shared "\Seen" flags
by Dave 29 Oct '09

29 Oct '09

(Running Dovecot 1.1.0) Is it possible to either - (a) Still have shared "\Seen" flags even while using the dovecot-shared file or (b) Indicate to Dovecot in some way other than the dovecot-shared file which permissions to use for any messages created? The problem is, in my shared folder (using symlinks) scenario I am using, I have to use the dovecot-shared file to make sure new messages get written with the correct user and group permissions so that everyone appropriate can access them, but I still would like the functionality of the shared "\Seen" flags in these shared/symlinked folders (which having dovecot-shared seems to knock out). Is it possible to do both somehow? Dave

Option (a) sounds like the cleanest solution, but a bit of testing showed that Postfix doesn't wait on deliver before replying to DATA so this seems to always result in a bounce. I've perused the postfix documentation but so far no luck; if anyone reading this has any insight on how we might configure postfix to behave this way, could you please let me know (maybe offlist would be best, as this may be considered somewhat off-topic). We are using something similar to option (b) currently, but it's not really an elegant approach and we would really like to move away from it. Option (a) sounds great, if we can somehow get it to work. TIA, Marty

[Dovecot] Question about Windows Mail for Vista IMAP client
by Stewart Dean 29 Oct '09

29 Oct '09

When TBird logs on, it does it quietly, that is it opens one or two logins. When you start working it'll open a few more. Quiet, no thrashing around When WM4Vista opens, it appears to login and disconnect (immediately) once for every folder a person has. 20 folders, 20 logins and disconnect, ripple fire. Anybody have an idea why WM4V is so busy and TB is quiet doing the same thing? I fell over this doing testing on V1.2.6 but find it's also the case back on my production V1.1.15 -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors. Now it's like an apartment in Bed-Stuy: you need three heavy duty pick-proof locks, one of those braces that goes from the lock to the floor, and bars on the windows.... ==== Stewart Dean, Unix System Admin, Bard College, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Wish-list: X-Delivered-To headers generated by dovecot-deliver
by Andrzej Adam Filip 29 Oct '09

29 Oct '09

Would it be sensible/"cost effective" to make dovecot-deliver generated X-Delivered-To header(s) based on command line parameter(s)? [after striping such existing headers, before consulting sieve] I need it to: a) *clearly* mark POP/IMAP account fetched by fetchmail [with fetchmail using directly dovecot-deliver in --mda option] b) cleanly implement "shared mailboxes" with MTA such as sendmail that can be easily forced to generate "one header per one recipient" [AFAIK] -- [pl>en: Andrew] Andrzej Adam Filip : anfi(a)onet.eu Order and simplification are the first steps toward mastery of a subject -- the actual enemy is the unknown. -- Thomas Mann
