Hi. I'm using dovecot 2.0.18 and I'm trying to authenticate through a CAS server (until now authentication was through MS Active Directory). I could not find anywhere some examples, so here is what i have done so far. -install phpcas and pam_cas -edit /etc/pam.d/dovecot auth sufficient /lib/security/pam_cas.so -simap://webmail.mydomain.com -f /etc/pam_cas.conf -edit /etc.pam_cas.conf host mycas.mydomain.com port 443 uriValidate /cas/proxyValidate ssl on proxy ??????????????????????? trusted_ca /etc/cert/certificate.pem debug on - and finally dovecot.conf which I'm sure is complety wrong userdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } passdb { driver = pam args = cache_key=%u dovecot } What I get in log is Oct 15 15:39:58 auth-worker: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Oct 15 15:39:58 auth-worker: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so Oct 15 15:39:58 auth-worker: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_mysql.so Oct 15 15:39:58 auth-worker: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_pgsql.so Oct 15 15:39:58 auth-worker: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Oct 15 15:39:58 auth-worker: Debug: Module loaded: /usr/lib64/dovecot/auth/libmech_gssapi.so Oct 15 15:39:58 auth-worker: Debug: pam(user,127.0.0.1): lookup service=dovecot Oct 15 15:39:58 auth-worker: Debug: pam(user,127.0.0.1): #1/1 style=1 msg=Password: Oct 15 15:39:58 auth-worker: Info: pam(user,127.0.0.1): pam_authenticate() failed: Permission denied Oct 15 15:40:00 auth: Debug: client out: FAIL 1 user=user Oct 15 15:40:00 imap-login: Info: Aborted login (auth failed, 1 attempts): user=<user>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Oct 15 15:40:00 auth: Debug: auth client connected (pid=9019) Any ideas?

[Dovecot] [sieve] - counting headers
by kjonca＠o2.pl 14 Oct '12

14 Oct '12

In some of my maildrop filters I have rules with weighted scoring[1], but only to count headers (for example to count "Received:" header) ie. all these rules are of form "/pattern/:h,1" Can dovecot sieve do this?

HELP! I have installed sendmail, dovecot, and squirrel mail. The squirrel mail portion of it works just fine, but I would like to have Mozilla Thunderbird as a client. Whenever I try and connect to the server it says "Thunderbird failed to find the settings for your email account." We do have an MX record in DNS pointing to our server. We are using Ubuntu 12.0.4.1, and have Dovecot 2.2.6 sendmail version 8.14.4-2ubuntu2 We are doing this for a class project and it is due by Tuesday 10/16/2012.. Thanks, Justin

[Dovecot] dsync ignores ssh-agent
by Mark Hills 12 Oct '12

12 Oct '12

I use IMAP over SSH, in pre-auth. I wanted to use dsync to offline mail to my laptop. dsync v2.1.10 would always ask for my SSH key/passphrase, ignoring ssh-agent. The culprit is the env_clean() in the stack below. Reading the source, I saw DOVECOT_PRESERVE_ENVS. When used as follows in my script it enables dsync to find my ssh-agent: export DOVECOT_PRESERVE_ENVS="SSH_AGENT_PID SSH_AUTH_SOCK" dsync mirror ssh imap.example.com /home/mark/opt/dovecot/bin/dsync and it now works without asking for password every time. I'm posting here so that anyone else googling for the same problem will hopefully find this, as I couldn't find anything about this in the docs. Also I'm interested in why dsync so aggressively cleans the environment; I tried a naive removal of env_clean() but this breaks basic functions. With this dsync is working very well for offline mail -- combined with alpine and a local exim for the outbound queue :) Thanks -- Mark Breakpoint 2, env_clean () at env-util.c:59 59 if (clearenv() < 0) (gdb) bt #0 env_clean () at env-util.c:59 #1 0xb7df10fc in master_service_env_clean () at master-service.c:454 #2 0xb7df26d4 in master_service_exec_config (service=0x809e7d0, input=0xbffff7e4) at master-service-settings.c:103 #3 0xb7df29be in config_exec_fallback (service=0x809e7d0, input=0xbffff7e4) at master-service-settings.c:153 #4 0xb7df2b65 in master_service_open_config (service=0x809e7d0, input=0xbffff7e4, path_r=0xbffff780, error_r=0xbffff7d8) at master-service-settings.c:206 #5 0xb7df3130 in master_service_settings_read (service=0x809e7d0, input=0xbffff7e4, output_r=0xbffff7dc, error_r=0xbffff7d8) at master-service-settings.c:345 #6 0x0805c672 in doveadm_read_settings () at doveadm.c:275 #7 0x0805c7d6 in main (argc=5, argv=0x809e1c0) at doveadm.c:342

[Dovecot] INBOX.INBOX.Sent causes problems in 2.0
by Christoph Bußenius 12 Oct '12

12 Oct '12

Hi, we have our namespace rooted at "INBOX.". Sometimes, users have folders like "INBOX.INBOX.Sent" or "INBOX.INBOX.INBOX.Sent". I do not know why these folders are created; I suspect it is due to buggy MUAs. If a mailbox like INBOX.INBOX.Sent exists, then in some cases Dovecot counts all messages in INBOX twice. This behavior can be demonstrated as follows: 1) Create a folder named "INBOX.INBOX.Sent" (using the IMAP CREATE command) 2) Save a message to "INBOX" (in my example the message is 7 MB) 3) dovecot-quota contains: priv/quota/storage 7129025 priv/quota/messages 1 4) doveadm quota recalc -u user1 5) Now dovecot-quota contains priv/quota/storage 14258050 priv/quota/messages 2 I.e. the user will experience that his quota fills up very fast. "doveadm -f flow fetch -u user1 'mailbox guid' ALL" prints: mailbox=INBOX guid=040ce73645177850497d000040c59ffc mailbox=INBOX guid=040ce73645177850497d000040c59ffc However, "doveadm -f flow fetch -u user1 'mailbox guid' mailbox INBOX" prints the message only once: mailbox=INBOX guid=040ce73645177850497d000040c59ffc How can we prevent this kind of confusion? What I'd like most is prevent the creation of these weird folders. Most MUAs have problems listing them properly, especially if both "INBOX.Sent" and "INBOX.INBOX.Sent" exist. Dovecot 2.1 does not seem to count anything twice. Cheers, Christoph Config: # 2.0.21: /usr/local/dovecot/etc/dovecot/dovecot.conf doveconf: Warning: service auth { client_limit=4096 } is lower than required under max. load (6224) # OS: Linux 2.6.32-42-server x86_64 Ubuntu 10.04.4 LTS disable_plaintext_auth = no mail_gid = vmail mail_location = mdbox:~/mail mail_plugins = quota mail_uid = vmail namespace default { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = scheme=CRYPT username_format=%u /usr/local/dovecot/etc/dovecot/users driver = passwd-file } plugin { quota = dict:ROOT::file:%h/dovecot-quota quota_rule = *:storage=5G } protocols = imap pop3 service auth { unix_listener auth-userdb { group = vmail mode = 0660 } } service imap { process_limit = 5000 } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /usr/local/dovecot/etc/dovecot/users driver = passwd-file } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_max_userip_connections = 20 mail_plugins = quota imap_quota } And the contents of the "users" file: user1:{plain}secret:::user1:/mail/users/user1:: -- Christoph Bußenius Rechnerbetriebsgruppe der Fakultäten Informatik und Mathematik Technische Universität München +49 89-289-18519 <> Raum 00.05.040 <> Boltzmannstr. 3 <> Garching

[Dovecot] [PATCH] dovadm plugins underlinking
by Natanael Copa 12 Oct '12

12 Oct '12

Hi, Running doveadm on Alpine Linux will show various underlinking errors: /usr/bin/doveadm: symbol 'acl_user_module': can't resolve symbol in lib '/usr/lib/dovecot/doveadm/lib10_doveadm_acl_plugin.so'. /usr/bin/doveadm: symbol 'acl_identifier_parse': can't resolve symbol in lib '/usr/lib/dovecot/doveadm/lib10_doveadm_acl_plugin.so'. ... (complete list is found here: http://bugs.alpinelinux.org/issues/1274) I understand that those are "harmless" (at least as long as you dont use those plugins), and even if some dynamic linkers are forgiving, the doveadm plugin modules are technically underlinked. The lib10_doveadm_acl_plugin.so uses symbol acl_user_module: $ nm -D /usr/lib/dovecot/doveadm/lib10_doveadm_acl_plugin.so | grep acl_user_module U acl_user_module That symbol is defined in lib01_acl_plugin.so: $ nm -D /usr/lib/dovecot/lib01_acl_plugin.so | grep acl_user_module 000000000020fb80 D acl_user_module Which means that lib10_doveadm_acl_plugin.so should be directly linked to lib01_acl_plugin.so.

hi- i'm setting up an imap proxy in front of a novell groupwise server. it seems to so far be partially working, but dovecot is having trouble in certain cases. i expect that it's ultimately due to what i believe is a very poor implementation of imap provided by groupwise [at least based on other experiences in the past] - but that's a big part of why i'd like to have dovecot in between it and clients. below is information collected during starting of dovecot, opening/initial connection from a client [os x mail.app], closing of the client, and stopping of dovecot. os is ubuntu 12.10 development/beta, dovecot is 2.1.7 courtesy of ubuntu's packages. log entries: Oct 11 13:24:33 halo dovecot: master: Dovecot v2.1.7 starting up Oct 11 13:24:49 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14171, TLS, session=<iHgu2cvLlwAKRChu> Oct 11 13:24:50 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14174, TLS, session=<t1E/2cvLoQAKRChu> Oct 11 13:24:51 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14176, TLS, session=<OZlM2cvLqgAKRChu> Oct 11 13:24:51 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14178, TLS, session=<d3NU2cvLsQAKRChu> Oct 11 13:24:51 halo dovecot: imap(jdoe): Connection closed in=16 out=350 Oct 11 13:24:52 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14180, TLS, session=<oxNa2cvLtAAKRChu> Oct 11 13:24:52 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:24:52 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14176 killed with signal 11 (core dumped) Oct 11 13:24:57 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:24:57 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14178 killed with signal 11 (core dumped) Oct 11 13:24:57 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14182, TLS, session=<FUCv2cvLuAAKRChu> Oct 11 13:24:58 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:24:58 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14180 killed with signal 11 (core dumped) Oct 11 13:25:03 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:25:03 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14182 killed with signal 11 (core dumped) Oct 11 13:25:03 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14184, TLS, session=<DQkF2svLuwAKRChu> Oct 11 13:25:03 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:25:03 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14184 killed with signal 11 (core dumped) Oct 11 13:25:09 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:25:09 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14174 killed with signal 11 (core dumped) [repeats] Oct 11 13:25:27 halo dovecot: dns-client: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: dns-client: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: master: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: auth: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: config: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: ssl-params: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: anvil: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: log: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) gdb backtrace: ~ >gdb /usr/lib/dovecot/imap /var/cache/imapproxy/jdoe/core GNU gdb (GDB) 7.5-ubuntu Copyright (C) 2012 Free Software Foundation, Inc.
