rip=192.168.200.6, lip=192.168.200.22, TLS, session=<EfvjiYfYrgCwxigG> seems client cert is ok, but Dovecot does not like Thunderbirds method to handle TLS-Cert login w/o username and password. Hint http://dovecot.org/list/dovecot/2012-December/069771.html does not seem to be valid for Dovecot 2.2 On the other hand I think it is not a suitable method to include CRLs into CA file. Certificate should include a link to CRL or - better - an URL to OCSP. Does Dovecot support OCSP? best regards Christian

[Dovecot] Altmove doesn't working after a dsync.
by Breno Moreira 22 Mar '13

22 Mar '13

Hi guys, I'm having a problem with the altmove command after a mailbox migration using dsync. What I'm trying to do is move some users from a datacenter to another and, for that, I'm using the dsync feature. First thing I do is run the dsync mirror command, and this is working properly, but all mails are moved to the main path, ignoring the ALT statement in the mail location. So, what I tried to do was run the doveadm altmove to move the old mails to the new alternate storage, but it simply doesn't work or sometimes moves only few messages. After the user receives new messages, these new files are correctly moved. It can be problem with my search parameter in the altmove command? Or this is a normal result? Best Regards, Breno Moreira -- --------------------------------------------------------------------- Breno Moreira

[Dovecot] How do I enable dsync sieve script replication?
by Oli Schacher 22 Mar '13

22 Mar '13

Hi all, Thank you Timo for adding sieve script replication to dsync, much appreciated! Should this run out of the box with 2.2.rc3 and latest pigeonhole+patch or does this have to be enabled in the configuration somehow? I upgraded my dsync replication test setup, but it doesn't sync sieve so far, so I'm not sure if this is a config issue or if I maybe made a mistake while upgrading/patching. btw: not sure if you saw this bugreport, dsync over tcp still produces "no command given" errors randomly (http://www.dovecot.org/list/dovecot/2013-March/088751.html) Thanks Oli #dovecot -n: # 2.2.rc3: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.22.1.el6.x86_64 x86_64 CentOS release 6.3 (Final) auth_master_user_separator = * auth_mechanisms = plain login dict { acl = mysql:/etc/dovecot/dovecot-dict-shares.conf quotadict = mysql:/etc/dovecot/dovecot-dict-quota.conf } disable_plaintext_auth = no doveadm_password = <munged> listen = * login_greeting = Dovecot ready. mail_max_userip_connections = 50 mail_plugins = " quota notify replication" 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 namespace { list = children location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Spam { auto = subscribe special_use = \Junk } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { acl = vfile:/etc/dovecot/acls acl_shared_dict = proxy::acl mail_replica = tcp:<munged>:1337 quota = dict:::proxy::quotadict quota_rule = *:storage=10M:messages=1000 quota_rule2 = Spam:ignore quota_rule3 = Trash:storage=+100M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=75%% quota-warning 75 %u sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = pop3 imap lmtp sieve service aggregator { fifo_listener replication-notify-fifo { user = fumail } unix_listener replication-notify { user = fumail } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = fumail mode = 0660 user = fumail } user = root } service dict { unix_listener dict { mode = 0600 user = fumail } } service doveadm { inet_listener { port = 1337 } } service imap { vsz_limit = 2 G } service lmtp { inet_listener lmtp { address = 127.0.0.1 port = 24 } process_min_avail = 5 unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } service managesieve { vsz_limit = 2 G } service pop3 { vsz_limit = 2 G } service quota-warning { executable = script /usr/local/bin/quotawarning.py unix_listener quota-warning { mode = 0666 user = fumail } user = fumail } service replicator { process_min_avail = 1 } ssl_cert = </etc/ssl/<munged>.crt ssl_key = </etc/ssl/<munged>.key userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { imap_client_workarounds = mail_plugins = " quota notify replication acl imap_acl quota imap_quota" } protocol pop3 { mail_plugins = " quota notify replication quota" pop3_uidl_format = %08Xu%08Xv } protocol sieve { managesieve_logout_format = bytes ( in=%i : out=%o ) } protocol lmtp { deliver_log_format = from=<%f> msgid=%m action=<%$> subject=%s mail_plugins = " quota notify replication sieve quota" postmaster_address = postmaster@<munged> quota_full_tempfail = yes } -- message transmitted on 100% recycled electrons

[Dovecot] v2.2 dsync_brain_lock() FLOCK compatibility issue on Solaris 11.1
by Walter Steiner 22 Mar '13

22 Mar '13

Hello, On Oracle Solaris 11.1 (Solaris gcc-45 package set) core libraries do not provide flock() anymore. in file: src/doveadm/dsync/dsync-brain.c in function: dsync_brain_lock() around line: 234 is a (maybe unintentional) fix reference to FLOCK locks. if (file_wait_lock(brain->lock_fd, brain->lock_path, F_WRLCK, FILE_LOCK_METHOD_FLOCK, brain->lock_timeout, &brain->lock) <= 0) { resulting in a runtime error about unsupported flock() locks. (HAVE_FLOCK is not set by configure script) Personally, I have just changed "FLOCK" to "FCNTL". [ I have tried brain->lock->lock_method but this seems not to be the correct way => compile time error: dereferencing pointer to incomplete type ] Walter

Re: [Dovecot] Problem with Prefetch User Database

I use PAM because of the easyness of blocking specific validated users - you can just add/remove them in a plain text file. Easy administration will be necessary because of the planned huge amount of users on the system (28.000), and sometimes blocking a user is highly time-dependent (e.g. if one answers to a phising mail and sending out his credentials which are then abused for sending spam). I would go over LDAP if there is an equivalent easy way to solve this over LDAP (easy blocking out users by e.g editing a plain text file) - is there any?

[Dovecot] 2.2.rc2: problem with acl_shared_dict
by Lutz Preßler 22 Mar '13

22 Mar '13

Hello, 2.2.rc2, configuration as before: acl_shared_dict=file:... The contents of this file is used for e.g. LISTing shared mailboxes. But even with file and directory beeing world writable, it's not written into on SETACL commands. Instead, at least sometimes (it seems to make a difference if GETACL is used before in the session) the imap process crashes on SETACL or DELETEACL. Feb 26 00:31:52 host dovecot: imap(13373, user) K64y8ZTWOgB/AAAB: Fatal: master: service(imap): child 13373 killed with signal 11 (core dumps disabled) Anything to do for further debugging? Working correctly with 2.1.15. Greetings, Lutz

[Dovecot] director's imap/pop3 login timeout
by Angel L. Mateo 21 Mar '13

21 Mar '13

Hello, We have two (load balanced) director servers in front of 4 dovecot backend servers. Yesterday we had a problem at backend servers for some users (our SSO was down, so IMAP users couldn't authenticate) and this triggered a problem in director servers where almost nobody could open a new session. In our director's logs I could see errors like this: Mar 20 20:52:47 myotis41 dovecot: imap-login: proxy(<user>): Login failed to 155.54.211.162:143: [UNAVAILABLE] Temporary authentication failure. [myotis32:2013-03-20 19:52:47] So, it seems it was trying to authenticate for 1 hour, after that it timed out the login. But this timeout is too long. Is this a director timeout? Or a backend timeout? How can I reduce it? -- Angel L.

[Dovecot] Log DNS revese IP address

Hi list. Is it possible to log the DNS reverse address of every login? I didnt find a variable *%{hostname}* but the wiki say it only works on *deliver_log_format* and not on *login_log_format_elements* Something like this: Mar 21 13:49:33 mailserver dovecot: pop3-login: Login: user=<myuser>, method=PLAIN, rip=10.10.10.15, lip=10.10.10.1, mpid=18712, *host=client02.example.com* Thanks!

Hi, I have set up ImapcProxy based on the wiki2 page. My server is set up for no plain text auth without starttls. When I am trying to login in the proxy server, I am getting an error Unknown username/password. The log says: *dovecot: imap-login: Aborted login (auth failed, 1 attempts in 2 secs): user=<xxx>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, TLS, session=<1pBG/03XogB/AAAB>* The server log: *dovecot: imap-login: Disconnected (tried to use disabled plaintext auth): rip=10.x.x.x, lip=10.x.x.y* Through wireshark, I found the username and password is going in plain text only to the server.

[Dovecot] Problem with Prefetch User Database
by megodin＠inboxalias.com 21 Mar '13

21 Mar '13

Hi there Community, I am currently setting up a Dovecot Mailserver, which works fine with some basic configuration (Dovecot + Sendmail). Sending and receiving Mails is just fine. For improving timings, I wanted to activate the prefetch user database - but apparently it doesn't seem to work correctly - I hope you can help me out! When I activate the prefetch user database, every time I get a "passdb didn't return userdb entries" from my mail.debug logs. Here's my config: passdb { driver = pam } # (I authenticate via PAM which is itself configured to ask ldap server, ldap returns it back to PAM - so Dovecot only sees the PAM-authentication part) userdb { driver = prefetch } userdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } # My userdb is going over ldap. Relevant parts of /etc/dovecot/dovecot-ldap.conf.ext: . .. user_attrs = uidNumber=50014,gidNumber=2084,modem-quota=quota_rule=*:storage=%$ user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uidNumber==50014,gidNumber=2084 I'm not sure.... maybe it's because of the PAMLDAPPAM? Or am I missing out something other fundamental? Thanks for any insights, Megodin --- Alle PostfÃ¤cher an einem Ort.

I'd prefer having this already prepared: In /etc/defaults/dovecot we should add: # Set amount of "open files" / ulimit -n ULIMIT_OPEN_FILES=16884 In /etc/init.d/dovecot we should add: # Set amount of open files / ulimit -n [ -n "$ULIMIT_OPEN_FILES" ] && ulimit -n $ULIMIT_OPEN_FILES Peer -- Heinlein Support GmbH Schwedter Str. 8/9b, 10119 Berlin http://www.heinlein-support.de Tel: 030 / 405051-42 Fax: 030 / 405051-19 Zwangsangaben lt. §35a GmbHG: HRB 93818 B / Amtsgericht Berlin-Charlottenburg, Geschäftsführer: Peer Heinlein -- Sitz: Berlin

[Dovecot] dovecot: auth-worker: order of authentication types
by David Obando 20 Mar '13

20 Mar '13

Hi all, I'm setting a mailserver using dovecot version: 2.1.7. On the server I have a couple of system users using PAM authentication and a lot of virtual users using SQL authentication. When a virtual user (e.g. david(a)virtdomain.de) logs in dovecot tries to authenticate the user via PAM and after failing it uses SQL: Mar 19 11:39:42 orange dovecot: auth-worker(7815): pam(david(a)virtdomain.de,<ip address>): pam_authenticate() failed: Authentication failure (password mismatch?) Mar 19 11:39:42 orange dovecot: auth: passwd(david(a)virtdomain.de,<ip address>,<T58IuUTYvgDZbill>): unknown user Mar 19 11:39:42 orange dovecot: imap-login: Login: user=<david(a)virtdomain.de>, method=PLAIN, rip=<...>, lip=<...>, mpid=7816, TLS Could I set up dovecot authentication so *users that authenticate with only their username (i.e. system users) always and only use PAM authentication *users that authenticate with their e-mail-address always and only use SQL authentication ???

[Dovecot] Override quota settings with LDAP
by Hanno Hirschberger 20 Mar '13

20 Mar '13

Hi all, my current Dovecot setup is fetching both the imap quota limit and the mail location settings from LDAP entries. user_attrs = [...] UDBmailQuota=quota_rule=*:bytes=%$, mailLocation=mail That is because we have 3 users who wants to fetch their mail from /var/mail/<username>. All the other users have maildir with maildir quota. The LDAP entry for /var/mail user looks like this: mailLocation: mbox:/var/empty:INBOX=/var/mail/<username>:INDEX=MEMORY Works fine with one exception: the mail quota for /var/mail users. The dovecot log gets spammed with: Mar 20 13:37:04 lmtp(2494, username): Warning: quota: Namespace '' is not Maildir, skipping for Maildir++ quota Mar 20 13:37:04 lmtp(2494, username): Error: opendir(/var/empty/.imap) failed: No such file or directory ... which is only logical, because there's no maildir for that user. I want to get rid of these error messages and like to ask you if there's a way to override the "quota = maildir:User quota" setting in my Dovecot configuration for the 3 /var/mail users. For example with an extra LDAP field? Sadly I don't really know how to realize this. Or is there any other / better way? You can look at my doveconf -n output here: http://pastebin.com/mJZ2CXbg Best regards, Hanno

[Dovecot] shared folders and "subscriptions = yes"
by Lars Uhlmann 20 Mar '13

20 Mar '13

Example (dovecot 1.2.15): ,-[dovecot.conf] | namespace public { | separator = / | prefix = management | location = maildir:/path/to/management | subscriptions = yes | } | | namespace public { | separator = / | prefix = sales | location = maildir:/path/to/sales | subscriptions = yes | } `----- To have all IMAP-Users automatically updated their shared folder structure I use "subscriptions = yes". This works with the side effect, that all IMAP-Users can see _all_ folders in every namespace even if they do not have "lookup" access. This is of course not wanted. Is it possible to have dovecot check the ACL file in the root of a namespace before it parses the subscrptions file? regards Lars

[Dovecot] dsync migration questions
by Michael Smith (DF) 20 Mar '13

20 Mar '13

We are currently in the process of replacing one of our customer mail systems with a dovecot solution. However, one of the sticking points right now is how to get the old mail to the new system. On the dovecot side, we are using mdbox storage. On the old system we are using qpopper/mbox mailboxes in the following setup. All user inboxes are in /mnt/mail/mail_spool. Only select, privileged, users have mail folders in /mnt/mail/mail_spool/FOLDERS/user/. I know, insane setup, but it's almost 18 years legacy now. Like this... /mnt/mail/mail_spool/user1.mbox /mnt/mail/mail_spool/user2.mbox /mnt/mail/mail_spool/user3.mbox /mnt/mail/mail_spool/user4.mbox /mnt/mail/mail_spool/FOLDERS/user2/folder1.mbox /mnt/mail/mail_spool/FOLDERS/user2/folder2.mbox Also, the UIDs between the old system and the new dovecot solution are different. User1 may have uid 2134 on the old system, but have uid 193847 on the new system. We've tried the following. Note: User Anakin has a single message already in the new inbox. mkdir -p /mnt/mail/mail_spool/.migrate/ ln /mnt/mail/mail_spool/anakin /mnt/mail/mail_spool/.migrate/inbox chmod 644 /mnt/mail/mail_spool/.migrate/inbox dsync -D -v -R -u anakin(a)domain.com backup mbox:/mnt/mail/mail_spool/.migrate/ ... chmod 600 /mnt/mail/mail_spool/.migrate/inbox /bin/rm -rf /mnt/mail/mail_spool/.migrate dsync(root): Debug: Loading modules from directory: /usr/lib64/dovecot dsync(root): Debug: Module loaded: /usr/lib64/dovecot/lib10_quota_plugin.so dsync(root): Debug: Module loaded: /usr/lib64/dovecot/lib20_zlib_plugin.so dsync(root): Debug: auth input: anakin uid=1000001228 gid=1000001228 home=/var/spool/mail/CC/1000001228 quota_rule=*:storage=0:messages=0 dsync(root): Debug: Added userdb setting: plugin/quota_rule=*:storage=0:messages=0 dsync(root): Debug: Effective uid=1000001228, gid=1000001228, home=/var/spool/mail/CC/1000001228 dsync(root): Debug: Quota root: name=User quota backend=dict args=:file:/var/spool/mail/CC/1000001228/dovecot.quota dsync(root): Debug: Quota rule: root=User quota mailbox=* bytes=0 messages=0 dsync(root): Debug: dict quota: user=anakin, uri=file:/var/spool/mail/CC/1000001228/dovecot.quota, noenforcing=0 dsync(root): Debug: fs: root=/var/spool/mail/CC/1000001228/mail, index=/var/spool/mail/CC/1000001228/index, control=, inbox= dsync(root): Debug: Namespace : Using permissions from /var/spool/mail/CC/1000001228/mail: mode=0700 gid=-1 dsync(root): Debug: Effective uid=1000001228, gid=1000001228, home=/var/spool/mail/CC/1000001228 dsync(root): Debug: Quota root: name=User quota backend=dict args=:file:/var/spool/mail/CC/1000001228/dovecot.quota dsync(root): Debug: Quota rule: root=User quota mailbox=* bytes=0 messages=0 dsync(root): Debug: dict quota: user=anakin, uri=file:/var/spool/mail/CC/1000001228/dovecot.quota, noenforcing=0 dsync(root): Debug: mbox: INBOX defaulted to /mnt/test/mail_spool/.migrate/inbox dsync(root): Debug: fs: root=/mnt/test/mail_spool/.migrate, index=, control=, inbox=/mnt/test/mail_spool/.migrate/inbox dsync(anakin): Debug: Namespace : Using permissions from /mnt/test/mail_spool/.migrate: mode=0777 gid=-1 dsync(anakin): Error: Can't delete mailbox INBOX: INBOX can't be deleted. dsync(anakin): Debug: Namespace : Permission lookup failed from /var/spool/mail/CC/1000001228/mail/mailboxes/INBOX_b6845831821c42517c490000a72406a4 dsync(anakin): Debug: Namespace : Using permissions from /var/spool/mail/CC/1000001228/mail: mode=0700 gid=-1 dsync(anakin): Debug: Namespace : Permission lookup failed from /var/spool/mail/CC/1000001228/mail/mailboxes/INBOX_b6845831821c42517c490000a72406a4 dsync(anakin): Debug: Namespace : Using permissions from /var/spool/mail/CC/1000001228/mail: mode=0700 gid=-1 dsync(anakin): Info: INBOX: only in dest dsync(anakin): Info: INBOX: only in source dsync(anakin): Error: Trying to open a non-listed mailbox with guid=814b6332541c425169490000a72406a4 dsync(anakin): Error: msg iteration failed: Couldn't open mailbox 814b6332541c425169490000a72406a4 dsync(anakin): Error: Trying to open a non-listed mailbox with guid=814b6332541c425169490000a72406a4 Nothing was migrated. In some other combinations, trying to reproduce them again, it does migrate the old mail, but first destroys the existing mail in the new mailbox. Our goal is to cut mail delivery over to the new dovecot system (which will result in existing emails before migration), and then migrate the old mail *while* maintaining message UIDs. This is the easiest way to ensure no "lost" email with the migration. What are we doing wrong, and how do we achieve our goals? Thanks in advance. -- Michael Smith

[Dovecot] Logon with Client Certificate and OTP fallback
by dovecot.pkoch＠dfgh.net 20 Mar '13

20 Mar '13

Dear Dovecot experts, we have unusual authentication requirements, namely: - almost all of our user are using a smartcard to connect with our mailserver. Thunderbird is our friend here as it will use the smartcard as an additional certificate store and Thunderbird will do client certificate based authentication when connecting via SSL with a mailserver - there's no way (at least that I know of) for our iPad users to use a smartcard, so our iPad and iPhone users use OTP token (http://www.gooze.eu/catalog/otp-tokens-oath-0) For 10 years we are using a very simple POP3-server where I replaced the authentication routines with my own functions and these function are doing the following: 1) if the connection was made without SSL refuse to connect 2) if the client was using a client certificate extract the username from the certificate. Since we cannot stop Thunderbird from sending a username/passowrd-combination we compare the username from the certificate with the username Thunderbird has sent. If the usernames matches we allow access and ignore the password. 3) if the client did not sent a client certificate we calculate the current OneTimePassword of the users OTP-token and compare that with the password Thunderbird has sent. If the passwords matches we allow access. If a OTP-password was validated it can be used for 24 hours so our OTP-users must use their tokens only once a day. Now we would like to switch from POP3 to IMAP, so here are my questions: - can Dovecot be CONFIGURED to do the above. I compiled it yesterday and SSL client authentication works as expected. OTP seems to be supported via PAM and I can write a PAM-modul for our OTP-tokens, so OTP would be possible too. But how do I tell Dovecot to do OTP-auth as a fallback for ClientCert-auth. - I already looked into the sourcecode of Dovecot. Seems like all the authentication routines were built as pluggable modules. Is there any documentation out there on how how to built my own auth-module. Integrating the OTP-auth directly into Dovecot would be a lot easier (for me) than creating a PAM-module, so I would prefer that. If there was interest from other people I would add some configuration options to Dovecot (for example the location of the OTP-token list). Otherwise I would just hardcode everything into the source.

[Dovecot] ACL to make mailboxes populated by master account Read Only for regular users.
by Alex Cherniak 20 Mar '13

20 Mar '13

We have a solution using Dovecot as a secondary mail archive. All mailboxes are populated/groomed by master account and the actual users have only read access. This is achieved by a simple ACL approach. dovecot.conf has protocol imap { mail_plugins = acl quota imap_quota zlib } plugin { acl = vfile:/etc/dovecot/acls:cache_secs=300 } /etc/dovecot/acls/.DEFAULT file is trivial: user=master lrwstipekxa owner lr It used to work with Dovecot 2.0.4 for years, but after upgrade to 2.0.18 users now have full access to folders created by master account and can delete, add and move mails. Should it behave this way? How can I "secure" mailboxes again? Any help is appreciated.

[Dovecot] Lot of dovecot process writes
by Angel L. Mateo 20 Mar '13

20 Mar '13

Hello, While monitoring my servers' behaviour (ubuntu 12.04 with dovecot 2.1.9, with about 70000 users) I have found that lots of disk usage is done by dovecot process (the parent process). Since lmtp, imap and pop3 connections are handle by their own process, what could be the reason of this? -- Angel L.
