[Dovecot] SA54438
by Timo Sirainen 14 Aug '13

14 Aug '13

http://secunia.com/advisories/54438/ Since I already got 3 private mails about this, here's the same reply for everyone (actually updated, now that I looked at the code): This was a v2.2-only bug. And it isn't really a DoS.. It only caused the one pop3 process to crash in assert, which was handling only the connection that had already disconnected. (Unless you were running a non-recommended configuration with multiple clients per process.) So the only problem it caused was that Dovecot logged an assert error and maybe wrote a core dump.

[Dovecot] Dovecot security
by Jay Khashan 14 Aug '13

14 Aug '13

Hi, THIS IS URGENT I have Debian Linux machine which I installed as a mail server with postfix, and dovecot. my mail server is setup to use SMTP relay. I currently have ports 143, 995, 25 & SSMTP ports open. in the last few days I have been under attack where email is being sent to fake email address for example xxx(a)evg-mail.org which does not exist in the mysql db. I need to figure out and lock down dovecot, because I believe the attack is some kind of virus /spyware. I need to know what statement in dovecot.conf or main.cf (postfix) I can modify to lock it down. Also open to install software to combat this kind of attack. Let me know what configuration files, info do you need to help out Many Thanks ~Jay

[Dovecot] HG changes affecting received headers
by Thomas Leuxner 13 Aug '13

13 Aug '13

Let me say this is a rather cosmetic issue, but it appears with the latest commits (around 2.2.5 release) the scheme of 'Received' headers has changed for LMTP: 1) Inet socket: Return-Path: <dfn-adv-bounces(a)dfn-cert.de> Delivered-To: <tlx(a)leuxner.net> Received: from spectre.leuxner.net ([188.138.0.199]) by spectre.leuxner.net (Dovecot) with LMTP id 8AkXDF5cA1LvDgAAZ53dLw for <tlx(a)leuxner.net>; Thu, 08 Aug 2013 10:52:46 +0200 2) UNIX socket: Return-Path: <dfn-adv-bounces(a)dfn-cert.de> Delivered-To: <tlx(a)leuxner.net> Received: from spectre.leuxner.net ([]) by spectre.leuxner.net (Dovecot) with LMTP id q8WuGflcA1I3DwAAZ53dLw for <tlx(a)leuxner.net>; Thu, 08 Aug 2013 10:55:21 +0200 3) Old (Pre 2.2.5) build, UNIX socket: Return-Path: <dfn-adv-bounces(a)dfn-cert.de> Delivered-To: <tlx(a)leuxner.net> Received: from spectre.leuxner.net by spectre.leuxner.net (Dovecot) with LMTP id 8NiKKX0h+lFRIAAAZ53dLw for <tlx(a)leuxner.net>; Thu, 01 Aug 2013 10:51:09 +0200 While it probably should resolve the FQDN in 1) (Postfix does), not sure what it should do with a UNIX socket in 2). Previously as shown in 3) it had none of it... Thomas

[Dovecot] Can't take user info from an alternate file
by dave＠661.org 13 Aug '13

13 Aug '13

I'm positive I did everything right to get Dovecot to take usernames and passwords from /etc/dovecot/users, but it still goes for /etc/passwd and /etc/shadow. The format of /etc/dovecot/users is "alice:{PLAIN}plaintextpassword" Here's my "doveconf -n": # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-51-virtual x86_64 Ubuntu 12.04.2 LTS auth_debug = yes auth_verbose = yes auth_verbose_passwords = plain hostname = papasmurf.foobar.com listen = * mbox_write_locks = fcntl passdb { args = scheme=PLAIN-MD5 username_format=%n /etc/dovecot/users driver = passwd-file } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0664 user = postfix } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = username_format=%n /etc/dovecot/users driver = passwd-file } I'm using Ubuntu Precise and version 2.0.19 of Dovecot. -- David Griffith dave(a)661.org

[Dovecot] Unlock non existent locks
by Thomas Hummel 12 Aug '13

12 Aug '13

Hello Timo, I'm running a single instance of dovecot-2.1.15 on a single host running 8.3-RELEASE-p3 FreeBSD amd64 mailboxes (Maildir), control files and indexes are on NFS (v3,tcp) mail_nfs_storage = yes lock_method = fcntl [didn't touch the following] # Mail index files also exist in NFS. Setting this to yes requires # mmap_disable=yes and fsync_disable=no. mail_nfs_index = yes served by an Isilon s200 node (OneFS 6.5.5.22) procmail delivers in the same location through postfix-2.8.7 The filer shows *a lot* of such messages : 2013-08-02T14:12:29+02:00 <0.5> XXXX-10(id10) /boot/kernel.amd64/kernel: [lkf_delegate.c:2752](pid 46390="kt: dwt3")(tid=101282) dev_local_lkf_unlock(): no lock entry present to unlock for resource: 1:19d5:fdbe ;client: 0xa51cc3f444107 Corresponding file may be a message, a maildir, an index, ... I can experience the same message with a simple fcntl C program which tries to unlock an NFS file without prior locking of it. However, the problem occurs only on a FreeBSD client (I tried the old nfs client and the new (mount_newnfs), not on a 2.6.32-358.11.1.el6.x86_64 CentOS release 6.4 (Final) Linux release. So my guess is that dovecot has some safety mechanism which tries to unlock locked files, maybe after some timeout and that, in the case of a an already unlocked file, the FreeBSD client sends the unlock RPC request to the server anyway whereas the linux client does not, noticing there isn't anything to unlock. Can you help me explaining such a behavior ? Are those "unlock a file with no prior lock" made on purpose or is it a bug ? Would it be an application or a RPC bug ? Can you think of another reason ?

[Dovecot] GUID Mismatch Issue
by Jeff Geiger 12 Aug '13

12 Aug '13

Dovecot 2.1.7 While migrating mail from one server (Maildir) to another (mdbox), a config issue caused my dsync to fail on a few accounts. Those accounts received mail on the new server over night and it autocreated new inboxes with new GUIDs. Now dsync wants nothing to do with mirroring between the two (diff GUIDs). Is there a way to fix this? dsync(jeff(a)foo.bar): Error: Mailbox INBOX changed its GUID (0eee4b021dcadd5158550000eed085a1 -> 43f87412a8f00352ac340000be821591) dsync(jeff(a)foo.bar): Error: msg iteration failed: Couldn't open mailbox 0eee4b021dcadd5158550000eed085a1 dsync(jeff(a)foo.bar): Error: Mailbox INBOX changed its GUID (0eee4b021dcadd5158550000eed085a1 -> 43f87412a8f00352ac340000be821591) dsync(jeff(a)foo.bar): Error: Mailbox Trash changed its GUID (0fee4b021dcadd5158550000eed085a1 -> 6300df050ef10352e9350000be821591) dsync(jeff(a)foo.bar): Error: Mailbox Sent changed its GUID (832d1e3663cadd515f5d0000eed085a1 -> 855ef505c0f00352fc340000be821591) I need a way to merge the mailboxes, in either direction, so I can clear out one side and successfully migrate the mail accounts. Any tips or pointers are greatly appreciated.

[Dovecot] multiple passdbs and auth sockets
by md＠Linux.IT 12 Aug '13

12 Aug '13

I have a few systems which run dovecot 1.x as the authentication backend for Postfix, with multiple auth { } sections like this one, each one with a different passdb and its own socket: auth ldap-10 { passdb ldap { args = /etc/dovecot/dovecot-ldap-10.conf } socket listen { client { path = /var/spool/postfix/private/auth-10 mode = 0666 } } } I need multiple sockets tied to multiple dbs because there are duplicated accounts, but after switching to dovecot 2.1.7 apparently *all* passdbs are checked and dovecot reports this message: Warning: Obsolete setting in /etc/dovecot/conf.d/auth-local.conf.ext:91: add auth_ prefix to all settings inside auth {} and remove the auth {} section completely doveconf shows that all my custom sockets are now part of a single "service auth { }" section, while all the passdbs appear at the top level. How can I update my configuration for dovecot 2.x? -- ciao, Marco

[Dovecot] Errors in SASL authentication ("attempted master login")
by Grzegorz Staniak 12 Aug '13

12 Aug '13

Hi, I'm using dovecot 2.2.4 (with Postfix 2.8.4) as both the SASL authentication backend and the delivery agent, and I keep getting lines like the following in the dovecot.log from the authentication subsystem: auth: passdb(toshiba1(a)domain,8.8.8.8,master): Attempted master login with no master passdbs (trying to log in as user: plain) The connections come from an old (embedded) mail client in a printer-fax machine. I googled for this specific error, but I only found info about old clients using "user\0user\0pass" string incorrectly during authentication, which caused a problem for earlier, development versions of dovecot. Actually, I recently migrated from 1.2 to 2.2.4 exactly to alleviate this situation, but the errors persist. Is there a way to remove the problem or work around it? Regards, GS -- Grzegorz Staniak <gstaniak [at] gmail _dot_ com>

[Dovecot] The docs a re a bit weird on "Directory hashing"
by Eliezer Croitoru 12 Aug '13

12 Aug '13

In squid we use a double layer of hashed directories on the FS to allow storage of millions of files. I was reading the "Directory hashing" section but never understood it.. since it's written.. in a way I could not understand. I am using this line: mail_location = maildir:/home/vmail/%d/%n/Maildir/ and I want to migrate to a hash based directory scheme. While trying to understand how that hash will work I stumbled a old thread at: http://www.dovecot.org/list/dovecot/2010-June/049695.html there they used: mail_location=maildir:/buzones/us.es/%1Hu/%2.1u/%n so I assume it should be used like that: mail_location=maildir:/home/vmail/%H/%2.256Hn/%d_%n/Maildir/ or: mail_location=maildir:/home/vmail/%1Mu/%2.1Mu/%d_%n/Maildir/ It's a bit hard to think alone so I hope you can assist me. let say I want to follow the model of squid cache_dir which has: cache_dir aufs /usr/local/squid/var/cache/squid 40000 16 256 And means a two layers cache of max 16 directories on the first layer and 256 directories on the second layer. The above allows millions of files storage and can benefit from all ext4 lower kernel levels of compatibly rather then do stuff on the user-land.. Since I am not 100% sure that the scheme I understood is indeed what I think I assume the above will need a small correction. Eliezer

[Dovecot] prevent dovecot from modifying maildirs
by Felix Rubio Dalmau 11 Aug '13

11 Aug '13

Hi all, Is there any possibility to ask dovecot to write nothing to disk, something like a "read only" state, without shutting it down? I have set up a ZFS+postfix+dovecot mail server, and I need both postfix (postsuper -h ALL) and dovecot (¿?) to stop modifying the disk to create the snapshot to be saved. Does anybody has any idea on how to achieve this? Regards! Felix

[Dovecot] constant Log synchronization error's
by Kim Bisgaard 10 Aug '13

10 Aug '13

Hi, I am seeing constant "Log synchronization error"s in my logs. See later for an example. This is dovecot 2.2.4, pigeonhole 0.4.1, and postfix 2.10.1 (with mailbox_command = /usr/libexec/dovecot/deliver) on a Fedora 19 system. I am using packages from Atrpms so there are some patches applied - ask for details. The mailboxes have resently been moved from a i386 system. I have tried to manually do "doveadm force-resync" for all users, but the problem persists :-( Here are an example from a user which does not use sieve: 11:45:48 Y dovecot: imap-login: Login: user=<X>, method=PLAIN, rip=62.199.61.123, lip=192.168.0.5, mpid=21531, TLS, session=<XxDNm3XhdAA+xz17> 11:45:52 Y dovecot: imap-login: Login: user=<X>, method=PLAIN, rip=62.199.61.123, lip=192.168.0.5, mpid=21541, TLS, session=<UewQnHXhAwA+xz17> 11:45:54 Y dovecot: imap(X): Error: mdbox /var/mail/X/mdbox/mailboxes/INBOX/Streams/dbox-Mails: map uidvalidity mismatch (0 vs 1283330954) 11:45:54 Y dovecot: imap(X): Disconnected: Internal error occurred.

[Dovecot] Mailbox Format
by Vijay Rajah 10 Aug '13

10 Aug '13

Hello List, I'm in the process of implementing a new mail server environment from scratch. I was wondering, what mailbox format is recommended? I have been using maildir format for my other projects. I would like to use some format that provides Single Instance Storage. I'm using postfix 2.11 and will use lmtp. I will be using dovecot 2.2.5 (Latest) version. I'm not planning on using NFS (if that matters) and will use dsync to backup mails to another server. Thanks in Advance Vijay Rajah

Re: [Dovecot] prevent dovecot from modifying maildirs

Filesystem consistency is different than, for lack of a better term, dovecot consistency. The latter places additional constraints on the content of files, rather than treating them as sequences of disk blocks. I don't think you can ensure the latter without stopping all dovecot processes (and maybe the MTA/LDA as well), which will be much more difficult and disruptive than just taking a snapshot. (I think some snapshot aware application like databases and hypervisors allows the operator to put the application in a state of acquiesence, long enough to take a snapshot, then unblock all processes after the snapshot.) I'd take the suggestion of the previous poster: take snapshots, don't worry, be happy. The small amount of inconsistencies is trivial compared with quickly recovering a mail store after disaster.

[Dovecot] Getting default uid/gid of users via socket for virtual user support for sendmail
by Steffen Kaiser 09 Aug '13

09 Aug '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm trying to make my life easier with sendmail and virtual users. For that I'd like to pass sendmail the home directory and uid/gid for each user. The user data is storred in a LDAP,& I retrieve it from the auth-userdb socket fine. If I add uid / gid to each user, I get them via that socket as well, but is there a way I get the default uid/gid? I mean, without calling an external program, such as doveadm. There is an "initialize" phase, so the default information is retrieved just once per lifetime of the demon, but each time the sendmail binary is invoked.

[Dovecot] Override master service settigs with spaces
by Ulrich Zehl 08 Aug '13

08 Aug '13

I'd like to override one setting for a master service in conf.d/10-master.conf. Unfortunately, said setting contains spaces, and I do not know how to escape them properly. Here's what I've tried so far. (Note: This is just the easiest/silliest test case I could come up with; not the actual setting or service I want to overwrite.) conf.d/10-master.conf: service quota-status { executable = quota-status -p postfix -o plugin/quota_status_success=Testing 1 2 3 inet_listener { port = 12340 } } Reaction: $ printf "recipient=test(a)example.org\nsize=0\n\n" | nc 127.0.0.1 12340 action=Testing conf.d/10-master.conf: service quota-status { executable = quota-status -p postfix -o "plugin/quota_status_success=Testing 1 2 3" inet_listener { port = 12340 } } Reaction: $ printf "recipient=test(a)example.org\nsize=0\n\n" | nc 127.0.0.1 12340 action=DUNNO [<-- This is the default setting] conf.d/10-master.conf: service quota-status { executable = quota-status -p postfix -o 'plugin/quota_status_success=Testing 1 2 3' inet_listener { port = 12340 } } Reaction: $ printf "recipient=test(a)example.org\nsize=0\n\n" | nc 127.0.0.1 12340 action=DUNNO [<-- This is the default setting] conf.d/10-master.conf: service quota-status { executable = quota-status -p postfix -o plugin/quota_status_success="Testing 1 2 3" inet_listener { port = 12340 } } Reaction: $ printf "recipient=test(a)example.org\nsize=0\n\n" | nc 127.0.0.1 12340 action="Testing [<-- Note the " after = ] conf.d/10-master.conf: service quota-status { executable = quota-status -p postfix -o plugin/quota_status_success=Testing\ 1\ 2\ 3 inet_listener { port = 12340 } } Reaction: $ printf "recipient=test(a)example.org\nsize=0\n\n" | nc 127.0.0.1 12340 action=Testing\ [<-- Note the \ ] I'm out of ideas now.

[Dovecot] Postfix aliases with quota-status service
by Thomas Leuxner 07 Aug '13

07 Aug '13

The latest HG commits seem to have fixed some underlying problems with the 'quota-status' service. Now doing some quick tests I wonder if this can be used with aliases on the Postfix side. Appears the 'check_policy_service' used in the example below will query existing users via Dovecot's Auth Backend: http://sys4.de/en/blog/2013/04/05/dovecot-quota-mit-postfix-abfragen/ http://www.postfix.org/SMTPD_POLICY_README.html This works fine for Dovecot user 'philo' where the mail is rejected upfront before it enters the queue: ==> /var/log/mail.log <== Jul 30 13:41:18 spectre postfix/smtpd[31072]: NOQUEUE: reject: RCPT from host.example.com[1.2.3.4]: 554 5.2.2 <philo(a)trashheap.net>: Recipient address rejected: Quota exceeded (mailbox for use r is full); from=<user(a)example.com> to=<philo(a)trashheap.net> proto=ESMTP helo=<host.example.com> Now user 'gunge' is an alias for 'philo' in Postfix, thus the quota check will not recognize the user, will queue the message and reject it at the MDA stage: ==> /var/log/mail.log <== Jul 30 14:41:02 spectre postfix/lmtp[31460]: 3c4HSD5ZkBzBP: to=<philo(a)trashheap.net>, orig_to=<gunge(a)trashheap.net>, relay=spectre.leuxner.net[private/dovecot-lmtp], delay=1.2, delays=1.1/0.01/0/0.13, dsn=4.2.2, status=deferred (host spectre.leuxner.net[private/dovecot-lmtp] said: 452 4.2.2 <philo(a)trashheap.net> Quota exceeded (mailbox for user is full) (in reply to end of DATA command)) This is probably intended behaviour, just want to make sure that I'm not missing a point here. For now the only fix that comes to my mind to create "quota aware" aliases - is creating 'dummy' users in Dovecot which point to the same mailbox rather than performing aliasing on the Postfix end. Open to suggestions... Regards Thomas

[Dovecot] v2.2.5 released

06 Aug '13

http://dovecot.org/releases/2.2/dovecot-2.2.5.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.5.tar.gz.sig So, I'm back from the first vacation I've had in about 10 years. (Well, maybe there were a few short ones.) I was planning on coding it the whole time, but looks like I didn't manage to get anything at all done. Maybe that's a good vacation?.. Anyway, I've still a few more pending things to look into, but it's been too long since v2.2.4 so here are the fixes so far. + SSL: Added support for ECDH/ECDHE cipher suites (by David Hicks) + Added some missing man pages (by Pascal Volk) + quota-status: Added quota_status_toolarge setting (by Ulrich Zehl) - director: Users near expiration could have been redirected to different servers at the same time. - pop3: Avoid assert-crash if client disconnects during LIST. - mdbox: Corrupted index header still wasn't automatically fixed. - dsync: Various fixes to work better with imapc and pop3c storages. - ldap: sasl_bind=yes caused crashes, because Dovecot's lib-sasl symbols conflicted with Cyrus SASL library. - imap: Various error handling fixes to CATENATE. (Found using Apple's stress test script.)

[Dovecot] Please HELP: how to delete all messages older than X days from the server?
by Răzvan Sandu 06 Aug '13

06 Aug '13

Hello, Would you please help me solve the following case? My (CentOS) server runs dovecot and allows both POP3 and IMAP service. Users are virtual users (no home directories), with messages stored in Maildir directories under /var/spool/mail/vhosts/example.com/username Some of them use mobile devices (without local storage space), so I must allow IMAP access, not just POP3. But the storage on the server must be for a strictly *limited* period of time. As an admin, I'm trying to force each user to: - download *locally* received messages when they arrive at the office - don't let copies of messages on the server (incoming, sent, trash, drafts, etc.) For various reasons, e-mail client configuration is not under my control (I can't rely on client configuration for implementing this). Implementing filesystem quotas is not an option because a. presently, all virtual users share same UID/GID on the server and b. administrative reasons (the "full quota" situation may occur unexpectedly and this is not tolerable in corporate policy). So I need EITHER: 1. a method of downloading locally *all* messages from the server (incoming, sent, trash, drafts, etc.) to the workstation, when the user consults his/her mailbox from a POP3 desktop client, thus completely *emptying* the user's mailbox on the server OR 2. an automatic, elegant but forceful method of deleting all messages older than X days (incoming, sent, trash, drafts, etc.) I've tried to use a line such as: doveadm expunge -u john.doe(a)example.com before 4w run as root, from a script in crontab, but for "expunge" doveadm won't let me skip the "-u" parameter (to perform the expunge for *all* users). Could you please help? Any sugestion is welcomed. Thanks a lot, Răzvan

[Dovecot] Using ldap and pam
by Bo Lynch 06 Aug '13

06 Aug '13

Having some issues with ldap logins. I am using Centos 5,dovecot-1.0.13-1.el5.rfx and openldap-servers-2.3.43-25.el5_8.1 Trying to get this to work with the SoGo interface. First I converted all my standard system users to ldap using the openldap-tools. This worked fine, however when a user changes there password they can no longer see there email. If they change it back to the original password mail can be seen. This has stumped me for a day or so so I was hoping someone could shed some light. /etc/dovecot.conf protocols = imap imaps disable_plaintext_auth = no mbox_read_locks = fcntl mbox_write_locks = fcntl protocol imap { } protocol pop3 { } protocol lda { postmaster_address = postmaster(a)example.com } auth default { mechanisms = plain login passdb pam { } passdb ldap { args = /etc/dovecot-ldap.pass } userdb passwd { } user = root user = root socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } dict { } plugin { } /etc/dovecot-ldap.conf hosts = 127.0.0.1:389 sasl_bind = no auth_bind = yes auth_bind = no ldap_version = 3 deref = never dn = cn=sogo,dc=ameliaschools,dc=com dnpass=password base = dc=ameliaschools,dc=com scope = subtree pass_attrs = uid=user, userPassword=password pass_filter = (uid=%u)

[Dovecot] How to troubleshoot LDA or LMTP?
by John Williams 06 Aug '13

06 Aug '13

Please forgive me if these are silly questions. I am a normal user, not a system administrator. I am using Dovecot as a kind of IMAP caching proxy, i.e. reading IMAP mail via Gnus + Dovecot + Offlineimap. I am trying to enable sieve functionality. *Desired behaviour* When Gnus (or whatever MUA) asks for new mail from Dovecot, that before Dovecot returns and answer, the sieve rules are executed. Please tell me if I completely misunderstand how the mail system works in this instance. *Actual behaviour* As far as I can tell, not only are the sieve rules not executed, but also neither LDA or LMTP is invoked. *What works* Running the scripts manually via `sieve-filter` works fine. The next time I read from my local dovecot server the mail is all in the desired place. Also, the LMTP service is running, listening on port 24. *What doesn't work* I thought the next step would be to execute dovecot-lda manually (as is suggested on the wiki and in numerous newsgroup posts), but I can't figure out how to do this. When I execute it as root and provide my non-root username via the -u option, it hangs. I can see that it spawns a child process that executes as the non-root user (specified with the -u option). So, could someone tell how to execute dovecot-lda manually please? Also, when does LMTP process messages? When sending mail via SMTP, or when reading mail via IMAP? I would prefer to use LMTP rather than LDA. *My environment* Fedora 19 & sendmail. Is any other information relevant, apart from the dovecot configuration? Thank you, John .2.4: /etc/dovecot/dovecot.conf # OS: Linux 3.10.4-300.fc19.x86_64 x86_64 Fedora release 19 (Schrödinger’s Cat) auth_socket_path = /var/run/dovecot/auth-userdb debug_log_path = /var/log/dovecot-debug.log disable_plaintext_auth = no hostname = falcon.novoalexandrovsk.ru info_log_path = /var/log/dovecot-info.log lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes login_greeting = Dovecot ready, folks! mail_access_groups = mail mail_debug = yes mail_location = mbox:~/mail/mailboxes:DIRNAME=mBoX-MeSsAgEs:INDEX=~/mail/index:CONTROL=~/mail/control:INBOX=/var/spool/mail/%u 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 ihave mbox_write_locks = fcntl namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_global_dir = /var/lib/dovecot/sieve/global/ sieve_global_path = /var/lib/dovecot/sieve/default.sieve } postmaster_address = johnfrombluff(a)gmail.com protocols = imap lmtp sieve service auth { unix_listener auth-userdb { mode = 0600 user = mail } } service lmtp { executable = lmtp -L inet_listener lmtp { address = 192.168.0.101 127.0.0.1 ::1 port = 24 } user = mail } service managesieve-login { inet_listener sieve { port = 4190 } process_min_avail = 1 service_count = 1 vsz_limit = 64 M } service managesieve { process_limit = 10 } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } protocol lmtp { info_log_path = /var/log/dovecot-lmtp-info.log log_path = /var/log/dovecot-lmtp-debug.log mail_plugins = " sieve" } protocol lda { info_log_path = /var/log/dovecot-lda-info.log log_path = /var/log/dovecot-lda-errors.log mail_plugins = " sieve" } protocol sieve { mail_max_userip_connections = 10 managesieve_implementation_string = Dovecot Pigeonhole, Asshole! managesieve_logout_format = bytes=%i/%o managesieve_max_compile_errors = 5 managesieve_max_line_length = 65536 }

[Dovecot] dovecot, spamassasin and lmtp
by alfdc 06 Aug '13

06 Aug '13

Hi, Ok, so I got rid of my procmail in favor of dovecot lmtp as my MDA. However, I lost the ability to tag the emails as SPAM or not. Before, this is done by procmail. Filtering is done by the Evolution client. Is there a way to do something similar now? I still want my filtering to be done by the Evolution. So I need something similar what procmail is doing i.e. altering the email header and putting some tag on it if it is a SPAM. Thanks. -- View this message in context: http://dovecot.2317879.n4.nabble.com/dovecot-spamassasin-and-lmtp-tp43709.h… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] script to test CATENATE
by Mike Abbott 06 Aug '13

06 Aug '13

Attached please find a perl script which tests the CATENATE support in dovecot. I used this to test my CATENATE implementation a few years ago and it runs fine against dovecot in OS X Server. When run against dovecot-2.2.4 though it always fails or hangs, which in some cases means we interpreted RFCs differently and in other cases means it's finding bugs; both conditions are worthy of scrutiny. (It's random-number driven so every run is different.) A couple months ago I reported a few simple bugs which this script found and you fixed them; thanks. Then it started finding problems for which it's harder to isolate simple reproducible test cases. Vacations and other work interceded but now Apple is pleased to give you the script itself to allow you to iterate faster. Here are some examples of it running. One time only, pass the --init argument to store some template messages used by the real tests: $ ./catenate.pl --host your.test.server --user testuser --password 1234 --init connecting (imaps)... capability... logging in... deleting old templates mailbox... creating templates mailbox... append1... Append succeeded append2... Append succeeded logout... success $ ./catenate.pl --host your.test.server --user testuser --password 1234 connecting (imaps)... capability... logging in... append1... Append failed as it should have (bad url): <append1 NO [BADURL ;invalid;] Invalid IMAP URL: Unexpected IMAP URL path segment: `;invalid;'.> append2... Append failed as it should have (bad url): <append2 NO [BADURL /inbox/;uid=99999999] Message not found.> append3... Append succeeded [...] All tests passed. $ If it concludes with anything other than "All tests passed" or hangs then it found something that it didn't expect and that should be examined. Use the --verbose option to see the entire client-server conversation. We hope that you find this script helpful to harden your CATENATE code. I will be happy to answer any questions.

[Dovecot] problems with expire plugin

Hi all, I'm experiencing problems to set-up the expire plugin in dovecot.

[Dovecot] Corrupted mboxes with v2.2.4, posix_fallocate and GFS2
by Francesco Prelz 05 Aug '13

05 Aug '13

Hi, on a clustered Dovecot server installation that was recently moved from a shared GPFS filesystem to GFS2, occasional corruptions in the users' INBOXes started appearing, where a new incoming message would be appended directly after a block of NUL bytes, and be scanned by dovecot as being glued to the preceding message. I traced this to the file extension operation performed in mbox_sync_handle_eof_updates, where the 'file_set_size' call is used. If available, file_set_size will use the posix_fallocate call. In GFS2 posix_fallocate increases the file size in 4 kB chunks (there seems to be no guarantee anyway that posix_allocate will extend a file by the exact size requested). After a successful posix_fallocate call, mbox_sync_handle_eof_updates currently proceeds in rewriting the mailbox starting from the originally intended 'file_size': 1306 if (file_set_size(sync_ctx->write_fd, 1307 file_size + -sync_ctx->space_diff) < 0) { 1308 mbox_set_syscall_error(sync_ctx->mbox, 1309 "file_set_size()"); 1310 if (ftruncate(sync_ctx->write_fd, file_size) < 0) { 1311 mbox_set_syscall_error(sync_ctx->mbox, 1312 "ftruncate()"); 1313 } 1314 return -1; 1315 } 1316 mbox_sync_file_updated(sync_ctx, FALSE); 1317 1318 if (mbox_sync_rewrite(sync_ctx, mail_ctx, file_size, 1319 -sync_ctx->space_diff, padding, 1320 sync_ctx->need_space_seq, 1321 sync_ctx->seq) < 0) 1322 return -1; When posix_fallocate extends the mailbox beyond the requested 'file_size', a variable size block of NUL bytes is left behind at the tail of the mailbox, with the side effects described above. I successfully worked around this issue by undefining HAVE_POSIX_FALLOCATE, as the performance penalty with falling back to direct block appends seems small. At least a size check (and possible truncation) after the mbox_sync_file_updated call above should probably be added. I thought that the issue would be anyway worth bringing to your attention. Thanks. Francesco Prelz INFN - Sezione di Milano

[Dovecot] Passing data safely in password_key?
by Attila Nagy 05 Aug '13

05 Aug '13

Hi, I would like to convert my custom POP/IMAP proxy to Dovecot's. In this proxy I do more than giving back user name, password and the host and I need extra information. Luckily all of them are available as variables, but more than one comes as user input (like user name and cleartext password) and I'm not sure how to pass them safely. Obviously I would need a separator, which is guaranteed not to show up either in user name and the cleartext password. Should I use escape (%E) here, or is there a better way?

[Dovecot] ACL not copied to new mailboxes
by Markus Weippert 05 Aug '13

05 Aug '13

Hi, I had some trouble with ACLs not being copied to new child mailboxes in dovecot 2.2.4. It doesn't matter whether it's a private, shared or public mailbox I create the folder in, the ACLs just seems to be ignored. Anyway, I debugged the executable and came up with the attached patch. Since I'm not a developer, I'm not 100% sure about this but it works for me now.

[Dovecot] [Metadata Plugin] Q: Source Repository
by Christoph Hintermüller 05 Aug '13

05 Aug '13

Hi I'm currently trying to package V14 of Metadata plugin for Ubuntu Quantal (https://launchpad.net/~privatedata/+archive/dovecot-2.2.2/) to be installed along with dovecot 2.2.4. According to my efforts packaging the plugin i do have some questions For future releases, is it possible to add a link to the current release on the meta data mercurial page which includes in the filename of the tar.gz archive the current version number of the plugin ( metadata-plugin-v14.tar.gz). That would allow to add an appropriate line in the debian/watch file to detect when a new release of the plugin is available. Currently i have to check mercurial page manually and use an updated version mangling entry to ensure that the packaging system downloads the latest version. The link would help to simplify this. Especially as the base link in my debian/watch file currently points to tip.tar.gz and not to the archive the linke of the V14 tag points to. The sources i got represent the tip.tar.gz downloaded on July 19th 2013 23:16 CET which likely do not exactly correspond to the contents of the archive containing sources of V14. Therefore a versioned link to the source archives of the latest version would simplify things a lot, especially adding patches released for the latest version. As well as reporting the following addition. Further I have added a doc directory stub, containing the configuration examples found in thread http://dovecot.2317879.n4.nabble.com/dovecot-metadata-8-released-tp10091.ht… Greetings Christoph

[Dovecot] Subfolders of Inbox with LAYOUT=fs
by Keith Edmunds 05 Aug '13

05 Aug '13

We've just converted to LAYOUT=fs. Some users had subfolders under Inbox, and for those users some MUAs no longer show those folders. The directory structure is that the cur, tmp and new folders are in the 'location' directory, but the subfolders are in $location/INBOX/$foldername. I am suspicious of this: 12 list "" INBOX * LIST (\HasNoChildren) "/" "INBOX" 12 OK List completed. I have tried moving the cur, tmp and new folders to $location/INBOX, and changing 'location' in dovecot.conf, but the subfolders still do not show. Question: is it legitimate to have subfolders of INBOX when using LAYOUT=fs? If so, what am I missing?

Hi all/Timo, When some of our users are composing a message in Thunderbird, I see a ton of these in the logs, and they keep repeating the entire time they are typing until the message gets sent... > 2013-08-05T10:34:42-04:00 myhost dovecot: imap-login: Login: user=<user(a)media-brokers.com>, method=PLAIN, rip=###.###.###.###, lport=993, mpid=8152, TLS, session=<El2GNTTjNgDAqAIc> > 2013-08-05T10:34:42-04:00 myhost dovecot: imap(user(a)media-brokers.com): Disconnected: Disconnected in IDLE in=149 out=12449 > 2013-08-05T10:34:42-04:00 myhost dovecot: imap-login: Login: user=<user(a)media-brokers.com>, method=PLAIN, rip=###.###.###.###, lport=993, mpid=8153, TLS, session=<lJedNTTjNwDAqAIc> > 2013-08-05T10:34:42-04:00 myhost dovecot: imap(user(a)media-brokers.com): Disconnected: Disconnected in IDLE in=149 out=12449 I confirmed that their 'Auto-Save' settings are the defaults (5 minutes, same as mine), and when I'm composing a message, there are no entries like this. The only other option I could think of that might affect t his is the 'spell check as you type', which is also enabled on mine. Also - I'm not sure this *always* happens to these users... all I know is, I see these flooding the logs sometimes, and when I remote in, that user is composing a message. Anyone have any idea why this happens to only a few of our users, and possibly only sometimes? Could it be something in the HTML of the quoted text when they are replying to certain messages? Thanks, -- Best regards, Charles

[Dovecot] Design: Adding checksums to index files
by Timo Sirainen 05 Aug '13

05 Aug '13

I've been planning on adding these for years. Maybe it's about time soon. I guess they could be added already to v2.2, but enabled only by a new setting because it requires file format changes that old Dovecots can't then read. I could probably patch v2.1 also so it is able to at least read the new format without failing. For v2.3 this new format could then be made the default. And what would the checksums be exactly? Would the standard CRC32 and CRC8 work fine, or are there any better ones? 1. dovecot.index v2.1+ always only fully recreates this file, never overwrites data to it. So the checksums could be written only when the dovecot.index is being recreated. There are 3 possible things to checksum: - header (32bit checksum) - all of the mail records (32bit checksum) - each mail record independently (8bit checksum per mail) The header's checksum could be verified every time the index is opened. The full mail record checksum could be verified when something appears to be wrong, but it's probably a waste of time to check it in normal operation. I'm not really sure about the per-mail checksums. It would be easy to create them while dovecot.index is being created, but after reading the file into memory the records are updated in many ways in many places. It's probably not worth the complexity and extra slowness to verify and/or update the checksums in all the different places. So is it worth it to even have them? In error conditions when fixing up indexes it could be useful to skip over records with broken checksums (and check if the mail is in dovecot.index.backup with correct checksum). Maybe that's enough to be worth 1 byte per message?.. 2. dovecot.index.log This file is only appended to. Each committed transaction could be prefixed in the new format with <transaction size><transaction 32bit checksum>. With the new format this wouldn't actually increase the log file size much, because there is already some space wasted for a compatibility "boundary" record that could be removed now. 3. dovecot.index.cache Cache file is the most complex file. Its headers get overwritten once in a while. Probably not worth the trouble to checksum the header itself, and there's not a lot that could be done even if a broken checksum was found. But each mail_cache_record could have its own checksum. A 8bit checksum could be added without increasing the file's size. Maybe that would be enough? 4. dovecot.index.thread This is a rather simple file and a 32bit checksum could be added to its header, and verified every time the file is read (because it's fully read anyway). 5. dovecot.mailbox.log This file doesn't even have a header. There are 3 unused bytes in each record currently. One of them could be used for a new "flags" parameter, with the only flag being "checksum added". There would still be space left for 8bit or 16bit checksum. 6. Other files There are also some text files, like dovecot-acl, subscriptions, quota usage and Sieve scripts. They probably have to be without checksums for now.

[Dovecot] How to configure sendmail using dovecot lmtp
by alfdc 05 Aug '13

05 Aug '13

Hi, I can't seems to find any posting on how to configure sendmail to use dovecot as lmtp. All I see is using it as LDA. I am particularly interested on how to tell sendmail to ask dovecot to deliver the message to the user. In the wiki for lda it says to add the following in the sendmail config: FEATURE(`local_procmail', `/usr/local/libexec/dovecot/deliver',`/usr/local/libexec/dovecot/deliver -d $u') MODIFY_MAILER_FLAGS(`LOCAL', `-f') MAILER(procmail) Is this the same for lmtp? If so how does it know when to use lda or lmtp? Beside, is procmail playing any role in any of these? Can the I just replace the whole thing as: FEATURE(`local_lmtp',`/usr/local/libexec/dovecot/deliver',`/usr/local/libexec/dovecot/deliver -d $u) MAILER(`local') Thanks. -- View this message in context: http://dovecot.2317879.n4.nabble.com/How-to-configure-sendmail-using-doveco… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Antispam folder names
by Jost Krieger 05 Aug '13

05 Aug '13

Is there anywhere a collection of folder names for the antispam_trash and antispam_spam configuration? Our problem is that in academia, you have a vast amount of different clients, and some, like Microsoft, use language-specific folder names *on the server*. So we're now collecting folder names to better handle the rare cases. Two more problems: 1. We needed to fix UTF-8 handling in the plugin, so that we kow canb say antispam_trash_pattern_ignorecase = gelöscht* in place of :set sp antispam_trash_pattern_ignorecase = gel&APY-scht* 2. Some clients allow prefixing the IMAP folders with a fixed name, often "INBOX". So we would like to specify something like antispam_trash_pattern_ignorecase = Junk*;*/Junk* which is not supported.

[Dovecot] Fileoperations in Maildir – problematic or okay?
by Martin Burgraf 05 Aug '13

05 Aug '13

Hi, I'm wondering: Is it a problem to move and delete files inside a dovecot-managed maildir? For example: I have a folder ~/.maildir/.Sub1.Start/cur and a folder ~/.maildir/.Sub1.Start.old/cur and like to regularly move old mails from the first to the second one. Can you create a cron job saying something like: find ~/.maildir/.Sub1.Start/cur -mtime +5 -exec mv {} ~/.maildir/.Sub1.Start.old/cur \; ? I guess this would be some sort of problem, wouldn't it? IIRC dovecot keeps indexes of the files inside a folder and moving them around like this may confuse the software, am I right? bye Martin

[Dovecot] ./configure dovecot
by LuKreme 03 Aug '13

When I do a ./configure in dovecot (2.2.1) I get this notice (first line): configure: WARNING: you should use --build, --host, --target Then, much later on: checking sys/ucred.h presence... yes configure: WARNING: sys/ucred.h: present but cannot be compiled configure: WARNING: sys/ucred.h: check for missing prerequisite headers? configure: WARNING: sys/ucred.h: see the Autoconf documentation configure: WARNING: sys/ucred.h: section "Present But Cannot Be Compiled" configure: WARNING: sys/ucred.h: proceeding with the compiler's result configure: WARNING: ## ---------------------------------- ## configure: WARNING: ## Report this to dovecot(a)dovecot.org ## configure: WARNING: ## ---------------------------------- ## checking for sys/ucred.h... no at the end I get: configure: creating ./config.status Install prefix . : /usr/local File offsets ... : 64bit I/O polling .... : kqueue I/O notifys .... : kqueue SSL ............ : yes (OpenSSL) GSSAPI ......... : no passdbs ........ : static passwd passwd-file pam checkpassword : -shadow -bsdauth -sia -ldap -sql -vpopmail userdbs ........ : static prefetch passwd passwd-file checkpassword nss : -ldap -sql -vpopmail SQL drivers .... : : -pgsql -mysql -sqlite Full text search : squat : -lucene -solr but there is no makefile created. ./configure --help just runs the configure script again, and none of --build --host or --target have any effect on the errors shown, including the first line error. So I think, ok, fine, I'll grab the latest build (2.2.4). Same result. OK, fine. Let's look at 1.2.17. Same thing, only without the cured.h warning. Still the same error on the first line after ./configure and still no make file. There's no big flashing warning anywhere that I can see that says, "Hey, dummy, this isn't going to work." config.log even ends with a "configure: exit 0" (The system already has dovecot 1.2.17 installed, but I was looking at installing $LATEST). -- May you live in interesting times

so if possible, I'd like an example of how to include system_groups_user in the userdb setup. I'm using ldap, but I could revert to using pam on ldap. There is a ldap query (gleaned from smbldap-tools) that will return a list of groups for a user (&(objectclass=posixGroup)(memberuid=%u)) but I don't know if the ldap driver will handle it but above all I can't figure out how it fits into the dovecot configuration! I'm trying to get Dovecot 2.1.7 on debian wheezy to recognize shared folders that have group ownership.

[Dovecot] Lowering Log Levels Back to Defaults
by Asai 02 Aug '13

02 Aug '13

Greetings, I'm sorry for asking what may be a really obvious question, but I'm having a hard time turning off logging, or at least getting less verbose logging. My dsync logs are about 7 MB daily, and I'm trying to get that switched off. At one point I had it on a lower level of verbosity, and I turned it up for debugging purposes, but now I cannot seem to turn it back down, which is something I did many times before. For example the logs are getting tons of Info level messages. dsync(asai(a)globalchangemusic.org): Info: expunge: box=Trash, uid=61625, msgid=<JIRA.14456.1367259371732.1046.1367259384800@hexagon>, size=9586 In dovecot.conf I have commented out the following include, which used to lower the log levels back to the defaults, but I've upgraded Dovecot recently to 2.2.4 from 2.1 something: #!include conf.d/10-logging.conf I had the default levels raised in that config file. I'm not sure this helps but: [vmail@triata ~]# doveconf -n # 2.2.4: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.32.1.el5xen x86_64 CentOS release 5.5 (Final) ext3 auth_mechanisms = plain login mail_home = /vmail/%d/%n/home mail_location = maildir:/vmail/%d/%n mail_plugins = " mail_log notify" 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 ihave namespace { inbox = yes location = prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } plugin { sieve = /vmail/%d/%n/sievescript } 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 } unix_listener auth-userdb { mode = 0660 user = vmail } user = root } service imap-login { process_min_avail = 3 service_count = 0 vsz_limit = 0 } ssl_cert = </etc/postfix/ssl/triata.globalchangemultimedia.net.pem ssl_key = </etc/postfix/ssl/triata.key userdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } protocol lda { hostname = triata.globalchangemultimedia.net mail_plugin_dir = /usr/lib64/dovecot/ mail_plugins = sieve postmaster_address = postmaster(a)globalchangemultimedia.net } protocol imap { imap_idle_notify_interval = 24 mins mail_max_userip_connections = 60 } -- --Asai

[Dovecot] Custom quota setup
by Richard Platel 02 Aug '13

02 Aug '13

(Dovecot 2.2-ee) We have a weird quota requirement, we have file storage that we manage through our own APIs but want that usage to come out of the user's mail quota. The usage is in a maildirsize like file uncreatively called filestoresize in the user's maildir. In the past we've been doing this by modifying the quota plugin and re-compiling, but it seems like it should be possible to do this via configuration. Is there a way to add a quota setting pointing at this file for additional usage (not limits)? The feature is used infrequently so it would probably be acceptable use the dirsize backend, but I can't figure out how to configure that to point at a certain directory. We pass custom quota rules for each user in our userdb, and use a custom dict proxy program, so that program could read the file and pass a setting at log in time too (if, for example, there was a setting that said "offset the user's quota usage by X amount") Thanks.

We do our own password auth (so we can support custom hash types, etc). I've only a private version of a HTTP-based passdb implemented for a customer. I'm not sure if I should bother adding something to be distributed with Dovecot, since I guess most people would want to modify it in some way anyway.

It'd be useful for us if the IMAP passdb could be used as a prefetch userdb. The remote IMAP server could respond with something like * OK key=value * OK key=value SEQ OK [CAPABILITY ...] Logged in. Or * OK <some JSON key value pairs> SEQ OK [CAPABILITY ...] Logged in. Would anyone else find this useful?

[Dovecot] 2.2.4 - Some questions about and needing help with quota-status
by Axel Luttgens 02 Aug '13

02 Aug '13

Help! I'm stuck. :-( The config of my experimental setup appears at the end of this message; I'm providing hereafter some more info that may not be immediately obvious. This is dovecot 2.2.4 with changesets 9091d0f2d971 and 2be295a0b64f. All involved databases are sqlite ones. passdb and userdb are devised so as to change usernames. For example, I could have a user with addresses "doe(a)oldexample.com", "johnd(a)oldexample.com" and "john.doe(a)example.com" needing to be able to log in as "jdoe" or "u123456"; all db lookups for that user then end with name "john.doe". This is a single mail user setup (user/group "dovemailer", uid/gid 999). Service lmtp has been configured to run as that user; that required a slight adjustment at the auth-userdb socket level. As a general rule, the quota dict appears to be correctly updated upon message arrivals and removals (thru lmtp, pop, imap), and to be correctly queried/interpreted by the various parts of the server. For example, thru the userdb query, user john.doe has been given an even lower quota limit than the already low default defined for testings: $ sudo doveadm quota get -u john.doe Quota name Type Value Limit % Quota utilisateur STORAGE 20 5 400 Quota utilisateur MESSAGE 14 - 0 and is clearly recognized as being over-quota by lmtp: $ telnet /_ROOT/var/run/dovecot/lmtp Trying /_ROOT/var/run/dovecot/lmtp... Connected to (null). Escape character is '^]'. 220 almba.local Dovecot ready. mail from:<mary.jane(a)example.com> 250 2.1.0 OK rcpt to:<john.doe(a)example.com> 250 2.1.5 OK data 354 OK Subject: test . 552 5.2.2 <john.doe(a)example.com> Quota exceeded (mailbox for user is full) Note that both services config and dict are launched if they aren't running. Since it has been previously seen that running quota-status as root comes with its own problems, and since it is a single user setup anyway, I'm trying to run it as dovemailer as well. So, let's try to see what quota-status thinks about john.doe: $ sudo -u _postfix telnet /_ROOT/var/spool/postfix/private/quota-policyd Trying /_ROOT/var/spool/postfix/private/quota-policyd... Connected to (null). Escape character is '^]'. Connection closed by foreign host. Clearly, not much... Looking in the log: dovecot[10554]: quota-status: Fatal: Error reading configuration: net_connect_unix(/_ROOT/var/run/dovecot/config) failed: Permission denied This thus raises a first question: Q1. What makes lmtp and quota-status different? How does lmtp manage to fetch all needed info, while quota-status seems to require an access to the config socket? Let's then slightly adjust dovecot.conf, in the hope to make quota-status happy: service config { unix_listener config { group = dovemailer mode = 0660 } } Q2. Should the above really be needed, wouldn't there be a better way? I ask, because it seems to me that I'm starting to seriously lose the benefits of privilege separation... Anyway, let's ask quota-status again: $ sudo -u _postfix telnet /_ROOT/var/spool/postfix/private/quota-policyd Password: Trying /_ROOT/var/spool/postfix/private/quota-policyd... Connected to (null). Escape character is '^]'. recipient=john.doe(a)example.com size=10000 action=OK ^] telnet> quit Connection closed. In the log: dovecot[11050]: auth: Debug: userdb out: USER 1 john.doe(a)example.com quota_rule=*:storage=5k dovecot[11050]: quota-status: Debug: auth input: john.doe(a)example.com quota_rule=*:storage=5k dovecot[11050]: quota-status: Debug: Added userdb setting: plugin/quota_rule=*:storage=5k dovecot[11050]: quota-status(john.doe(a)example.com): Debug: Effective uid=999, gid=999, home=/_Mailstores/john.doe dovecot[11050]: quota-status(john.doe(a)example.com): Debug: Quota root: name=Quota utilisateur backend=dict args=john.doe:proxy::sql_quota dovecot[11050]: quota-status(john.doe(a)example.com): Debug: Quota rule: root=Quota utilisateur mailbox=* bytes=5120 messages=0 dovecot[11050]: quota-status(john.doe(a)example.com): Debug: Quota grace: root=Quota utilisateur bytes=512 (10%) dovecot[11050]: quota-status(john.doe(a)example.com): Debug: dict quota: user=john.doe, uri=proxy::sql_quota, noenforcing=0 dovecot[11050]: quota-status(john.doe(a)example.com): Debug: fs: root=/_Mailstores/john.doe/mboxes, index=, indexpvt=, control=, inbox=/_Mailstores/john.doe/mboxes/inbox, alt= It is to be noted that the config server is now launched as expected, but that the dict server still isn't. Trying a dirsize backend instead of the dict backend doesn't help. The problem seems to be circumscribed to the interaction with the quota backend since, for example, querying quota-status for an unknown recipient yields an expected "action=REJECT Unknown user". Hence my last question, after having tried a lot of things for several days now, with no more success: Q3. What am I doing wrong?

[Dovecot] mails delivered to the wrong user when using lmtp_proxy and reject_unverified_recipient
by Peer Heinlein 02 Aug '13

02 Aug '13

Hi, looks like we detected a serious bug in dovecot's lmtp proxying where e-mails are delivered to the wrong user. The setup is: *) Dovecot is configured with "lmtp_proxy=yes" # Support proxying to other LMTP/SMTP servers by performing passdb lookups. lmtp_proxy = yes *) Postfix uses "dynamic recipient verification", so Postfix starts sending a (verify) mail by LMTP to dovecot, but quits the lmtp-session right after the RCPT TO:. No DATA-stage is reached in the protocol and no real e-mail is sent. But Postfix had a LMTP-connection for "user1". *) Just some seconds later a "real" e-mail to "user2" has to be delivered to dovecot by LMTP. But Dovecot will deliver this mail to the wrong "user1" instead of "user2". Looks like dovecot re-uses the (still opened?) lmtp-proxy-connection from "user1" to deliver an e-mail to "user2". Have a log at the protocol: 1) There's a verify call to user1 from Postfix: Jul 19 13:49:49 mailms postfix/lmtp[9842]: DE653280C51: to=<user1(a)example.com>, relay=localhost[127.0.0.1]:24, conn_use=2, delay=120, delays=117/0.45/0/2.5, dsn=2.1.5, status=deliverable (250 2.1.5 OK) 2) Just five seconds later the e-mail to user2 (see Postfix' point of view in the last line) is delivered to user2 (see result from Dovecot in the last line): Jul 19 13:50:04 mailms dovecot: lmtp(10965, kraemer): save: box=INBOX, uid=49880, msgid=<59798276-E5D1-4053-A570-9901B731DF5D(a)example.come>, size=11020 Jul 19 13:50:04 mailms dovecot: lmtp(10965, kraemer): 1zTeKrMn6VHVKgAAhyqEuA: msgid=<59798276-E5D1-4053-A570-9901B731DF5D(a)example.com>: saved mail to INBOX Jul 19 13:50:04 mailms postfix/lmtp[10953]: C25FC280BE5: to=<user2(a)example.com>, relay=localhost[127.0.0.1]:24, conn_use=19, delay=116, delays=115/0.53/0/0.33, dsn=2.0.0, status=sent (250 2.0.0 <user2> 1zTeKrMn6VHVKgAAhyqEuA Saved) Same with user3 and user4: Jul 19 14:47:53 mailms postfix/lmtp[10845]: C389A2809D7: to=<user3(a)example.com>, relay=localhost[127.0.0.1]:24, delay=4.7, delays=3.7/0.87/0/0.19, dsn=2.1.5, status=deliverable (250 2.1.5 OK) Jul 19 14:47:55 mailms dovecot: lmtp(26546, fs211113): save: box=INBOX, uid=8504, msgid=<928729810.113.1374238063381(a)example.com>, size=233151 Jul 19 14:47:55 mailms dovecot: lmtp(26546, fs211113): MbMvI2816VGyZwAAhyqEuA: msgid=<928729810.113.1374238063381(a)example.com>: saved mail to INBOX Jul 19 14:47:55 mailms postfix/lmtp[22524]: 6F0D2280A6E: to=<user4(a)example.com>, relay=localhost[127.0.0.1]:24, conn_use=2, delay=10, delays=8.4/1/0/0.8, dsn=2.0.0, status=sent (250 2.0.0 <user3> MbMvI2816VGyZwAAhyqEuA Saved) The user itself is quite normal in the user database (but has a mailhost=127.0.0.1 set): root@mailms:/etc/dovecot/conf.d# doveadm user user2(a)example.com userdb: user2(a)example.com uid : 5000 gid : 5000 home : /srv/mail/user2 root@mailms:/etc/dovecot/conf.d# doveadm auth user2(a)example.com Password: passdb: user2(a)example.com auth failed extra fields: user=user2 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

Hi, Are log lines like the following: Jul 28 15:30:50 mx1.somewhere dovecot: auth-worker(18980): sql(user(a)domain,217.67.x.x): unknown user Jul 28 15:32:56 mx1.somewhere dovecot: auth-worker(18980): sql(user(a)domain,212.182.x.x): Password mismatch written every time any authetntication phase fails, in SASL as well as in POP3/IMAP mailbox access? I have a legacy app that would gain a lot if I could distinguish between failed SASL authentication and failed POP3/IMAP authentication. I know I can use the "auth failed" lines for the latter case, and postfix log lines in the former, but they don't contain user info. Is there a way for log monitoring software to get failed login lines with both user info, and the reason (SASL, POP3, IMAP)? Regards, -- Grzegorz Staniak <gstaniak [at] gmail _dot_ com>

[Dovecot] 2.2.4 - quota-status changing the user it is running as
by Axel Luttgens 02 Aug '13

02 Aug '13

Hello, I'm currently experimenting with this quota-status service configuration: service quota-status { client_limit = 1 executable = quota-status -p postfix # Let's make the default explicit. user = root unix_listener /var/spool/postfix/private/quota-policyd { user = postfix } } The idea is to run the service as root during the preliminary tests (at worst, since the service is going to be used as a policy daemon by Postfix only, it shouldn't be very problematic to have it running as root anyway). A user, with address john.doe(a)example.com and identified as john.doe, is known to be over-quota. A "doveadm quota get" returns: $ sudo doveadm quota get -u john.doe Password: Quota name Type Value Limit % Quota utilisateur STORAGE 5 5 100 Quota utilisateur MESSAGE 9 - 0 and messages for that user are correctly rejected by lmtp: dovecot[4989]: lmtp(5069, john.doe(a)example.com) QWSWLgrP4lF7FAAA5Q0ykw: msgid=<20130714161643.9085DF176F2(a)ALMba.local>: save failed to INBOX: Quota exceeded (mailbox for user is full) Let's now simulate a connection from Postfix: $ sudo -u postfix telnet /_ROOT/var/spool/postfix/private/quota-policyd Trying /_ROOT/var/spool/postfix/private/quota-policyd... Connected to (null). Escape character is '^]'. A look at the output of top (excerpt) confirms that quota-status is running as root: PID COMMAND UID 5100 quota-status 0 Going on with our telnet session: recipient=john.doe(a)example.com size=10000 action=OK Hmmm... OK, this may be a config problem of mine which may require further investigation. Anyway, looking at top's output: PID COMMAND UID 5100 quota-status 999 it appears that quota-status is now running as the mail_uid/mail_gid user; the switch happens immediately after having entered the empty line in the telnet session. Let's then try to go further within the telnet session: recipient=john.doe(a)example.com size=10000 action=DEFER_IF_PERMIT Internal error occurred. Refer to server log for more information. ^] telnet> quit Connection closed. and a look at the log indeed reveals that quota-status doesn't have sufficient privileges anymore: dovecot[4989]: quota-status(john.doe(a)example.com): Error: user john.doe(a)example.com: Error reading configuration: net_connect_unix(/_ROOT/var/run/dovecot/config) failed: Permission denied Is this the expected behavior, to have quota-status switch to another user?

[Dovecot] [PATCH] quota-status: allow different action for messages that are too large (over maximum quota)
by Ulrich Zehl 02 Aug '13

02 Aug '13

This proposed patch to quota-status allows the administrator to return different actions for messages that (a) cannot currently fit in the quota (because there's not enough free space) and (b) are over the maximum quota limit (and could not even be delivered if the mailbox was empty). Configuration works like this: plugin { quota_status_overquota = DEFER_IF_PERMIT 4.2.2 Mailbox full quota_status_toolarge = REJECT 5.2.3 Message length exceeds administrative limit } The patch is backwards compatible: If quota_status_toolarge is not set, quota_status_overquota is returned. No changes are necessary in setups where the new feature is not desired. The reason I developed this patch is: In my environment, I have mostly POP3 mailboxes, where condition (a) changes frequently (usually after each login), but condition (b) will almost never change (users do not get additional mailbox space often). Thus, I'd like to avoid bouncing mails that could be delivered half an hour later. This patch works for 2.2 and 2.1. (This assumes you have already applied the trivial patch I sent earlier; otherwise patch(1) will report some fuzz.) What do you think of this?

[Dovecot] misconception in uid and gid
by Felix Rubio Dalmau 02 Aug '13

02 Aug '13

Hi, I'm using a SQL database to store the usernames and passwords of my users. However, I have found that I must explicitly return the uid and gid with every query, even though all virtual users use the same uid and gid. The query, that works, is: user_query = SELECT mail, 'vmail' AS uid, 'vmail' AS gid, home, CONCAT('*:storage=', quota_MB*1024) AS quota_rule \ FROM virtual_users AS V LEFT JOIN virtual_domains AS D ON V.domain_id=D.id WHERE V.user='%n' AND D.name='%d' Nevertheless, if I remove the segments "'vmail' AS uid, 'vmail' AS gid" and modify the file conf.d/10-mail.conf to show mail_uid = vmail mail_gid = vmail I get this error: dovecot: auth: Error: userdb(<mail>): client doesn't have lookup permissions for this user: userdb reply doesn't contain uid (change userdb socket permissions) Does anybody know what is wrong in my set-up? Regards, Felix

Hello Axel, but then I don't get it: I thought that "uid" and "gid" in the user_query where used to access the local FS, whereas the "unix_listener auth-userdb" are used to indicate under which owner/group must be auth-userdb run... although maybe I'm wrong :-S :-) What I'm looking forward to is to eliminate the need for returning these two fixed items, as long as all the virtual_users will be using the same uid and gid. Does anybody know how can I do it?? Regards, and thank you!

[Dovecot] Wrong remote IP (rip) in mail.log using IMAP login
by tyli 02 Aug '13

02 Aug '13

Dear list users While trying to secure our dovecot server with fail2ban I came across the following problem: We use dovecot (1.2.9, ubuntu package) behind a NAT, and failed login attempts are logged with our firewall as the remote ip. Example: Apr 15 08:36:26 mail dovecot: imap-login: Disconnected (auth failed, 6 attempts): user=<xy>, method=PLAIN, rip=192.168.0.1, lip=192.168.0.3 Therefore I would ban 192.168.0.1 which means that I ban EVERY user. Funny thing is that POP3 login attempts are logged correctly: Apr 13 11:05:50 mail dovecot: pop3-login: Disconnected (auth failed, 1 attempts): user=<sgvyniwx>, method=PLAIN, rip=217.81.27.55, lip=192.168.0.3 Any ideas how to change this? Thanks in advance tyli

[Dovecot] trouble with setting individual quota values for multiple namespaces
by Andreas Oster 01 Aug '13

01 Aug '13

Hello all please apologize that I repost this problem again. I tried to get some help several times on the list but did not find/get a solution. I am still struggling to setup different quotas for namespaces. In addition to the default "INBOX" namespace I have created a namespace called "MailArchive" which should have its own quota value of 5G per user. At first I configured quota2 like this: quota2 = maildir:MailArchive quota:ns=MailArchive/ quota2_rule = *:storage=5G and this seemd to work quite well. Users, accessing the MailArchive namespace can see the 5G limit in their mail client, unfortunately in the mail.err log file, errors like these repeatedly appear: Jul 29 11:40:24 mailserver dovecot: imap(testuser): Error: quota: Unknown namespace: MailArchive/ Jul 29 11:41:43 dovecot: last message repeated 47 times In the WIKI I have read, that in order to have quota for different namespaces, one would have to use different quota backends so I changed the quota config for the MailArchive namespace to SQL. namespace inbox { disabled = no hidden = no ignore_on_failure = no inbox = yes list = yes location = mailbox Drafts { auto = subscribe driver = special_use = \Drafts } mailbox Junk { auto = subscribe driver = special_use = \Junk } mailbox Sent { auto = subscribe driver = special_use = \Sent } mailbox "Sent Messages" { auto = no driver = special_use = \Sent } mailbox Trash { auto = subscribe driver = special_use = \Trash } prefix = separator = / subscriptions = yes type = private } namespace { disabled = no hidden = no ignore_on_failure = no inbox = no list = yes location = maildir:/var/vmail/archive/%Ln/Maildir mailbox "Archived Mails" { auto = subscribe driver = } prefix = MailArchive/ separator = / subscriptions = yes type = private } plugin { quota = maildir:User quota:ns= quota2 = dict:Archive Quota:%u.mailarchive:ns=MailArchive/:proxy::sqlquota quota2_rule = *:storage=5G quota_rule = *:storage=1G quota_rule2 = Trash:storage=+200M } dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } Unfortunately this did not change anything. Quota is working like expected but I still get the same errors in mail.err. I am currently using dovecot version 2.2.4. Thank you for your kind help best regards Andreas

I think the cause is clear enough: you (user=md5i/uid=1000) are not part of group mail (gid=8), so the dovecot user process doing things on your behalf cannot create index files that are anlogous to the mailbox it's indexing. You can either 1) add "md5i" to group mail 2) remove g+w permission on your mail files (making group membership irrelevant) 3) fiddle with "mail_privileged_group = mail", but I'm a little hazy on all the ramifications of this. I don't know your particular circumstances, so I don't know which is best. If (big if) nothing on your system (particularly the MTA) requires access to your mail spool files by running as group=mail, probably 2) is your best option. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] LMTP: userdb lookup - user-filter with variables
by Burckhard Schmidt 31 Jul '13

31 Jul '13

I tried to use dovcots lmtp instead of dovecot-lda. postfix has in master.cf ... dovecot-lda -f ... -d ${user} to separate the user part from user(a)hostname.domain. So lookup of "user" succeeds in userdb (LDAP) done by dovecot-lda. I have always local addresses like to=<user(a)hostname.domain> postfix/lmtp[6579]: [ID 197553 mail.info] B3CDA66A16: to=<h0094slk(a)mailstore4.hu-berlin.de> With lmtp the userpart must be separated also. I tried user_filter (LDAP) with %n, %Ln, %8n without success: userdb lookup: user(a)hostname.domain doesn't exist) dovecot-2.1.17 I used "doveadm user h0094slk" and "doveadm user h0094slk(a)mailstore4.hu-berlin.de" for my tests. userdb { driver = ldap args = /usr/dovecot/etc/ldapuser.conf } and ldapuser.conf with ... user_filter = (&(uid=%n) (objectClass=cmsAccount)) user_attrs = homeDirectory=home I modified user_filter like uid=%Ln or uid=%8u success for doveadm user h0094slk (because nothing to split) userdb: h0094slk home : /home/p0094/h0094slk but no success for doveadm user h0094slk(a)mailstore4.hu-berlin.de userdb lookup: user h0094slk(a)mailstore4.hu-berlin.de doesn't exist It looks for me like user_filter do not use variables at this point?

"Hogging" CPU and memory is putting it strongly, as it is basically suspended while blocked on waiting for a connection, and if left for a long time in an idle state, might be swapped out to disk and not consuming (real) memory, or consuming real memory that isn't in use otherwise. As I stated before, the resource usage is small compared with all the other stuff going on, so if you don't have a busy mail server, I don't think you should sweat the difference. The benefits of LMTP should increase with load, as having LMTP resident will save you the overhead of repeatedly loading/unloading LDA, and I'm sure the CPU and memory usage of servicing that overhead will be non-trivial. If you have oodles of memory, then it's no problem keeping a LMTP resident. If you don't have enough memory and are VM disk thrashing, you'll have other problems and LDA/LMTP is the least of your worries. > And when it's running as root there is always the danger > of privilege escalation. LDA only runs when it's needed and since it > uses only user rights it shoudbe more harmless. I didn't contest the privilege separation aspect, as it a necessary design trade-off that one daemon doing things for all user will need overriding access. However, if this is a concern, you can virtualize all your users. LMTP can theoretically be subverted, but at least won't be as root. (I'm assuming LMTP stays as root, and not spawning off user processes to do the real work.) Joseph Tam <jtam.home(a)gmail.com>

Well, the background process is hogging CPU and RAM while it basically does nothing. And when it's running as root there is always the danger of privilege escalation.

[Dovecot] LDA vs. LMTP
by Martin Burgraf 30 Jul '13

30 Jul '13

Hi there, I'm using Dovecot together with Postfix; as I understand it, there are two ways to transfer the mail from Postfix to Dovecot. 1.) by using LDA with mailbox_command = /usr/libexec/dovecot/dovecot-lda -f "$SENDER" -a "$RECIPIENT" 2.) by using LMTP with mailbox_transport = lmtp:unix:private/dovecot-lmtp (currently using number 1) I'm interessted in the differences and the advantages/disadvantages of each of those solutions. According to http://wiki2.dovecot.org/LDA the recommended way is to use LMTP, since it's supposed to have a better performance. On the other hand, http://wiki2.dovecot.org/LMTP says, that LMTP is a backgound process, while LDA is only called when needed. I've also read, that LDA only uses the users privileges, which both means, that LDA should be better. I've also noticed, that LMTP adds an additional Recieved:-Header to the mail. Are there any other differences? Thank you M.

[Dovecot] Maildir permissions and Solr re-indexing
by Michael Welsh Duggan 29 Jul '13

29 Jul '13

I am running a very small dovecot installation with only one user (me). I use the Solr indexer for indexing. Due to complicated reasons, I was forced to remove all the indexes and need to re-index everything. All the files in my Maildir are owned by md5i:mail (I am md5i), and have 660 permissions. All directories have the same user:group permissions, and 770 with the setguid bit set. (That last may not be necessary, but I was trying several things to get my use case to work.) Unfortunately, I can't seem to get re-indexing to work. When I do "doveadm fts rescan -A" as root, I get the following error for each of my subgroups: doveadm(md5i): Error: fchown(/home/md5i/Maildir/.mail.test/dovecot.index.log.newlock, group=8(mail)) failed: Operation not permitted (egid=1000(md5i), group based on /home/md5i/Maildir/.mail.test - see http://wiki2.dovecot.org/Errors/ChgrpNoPerm) After this, each directory has a dovecot.index.log with md5i:md5i 600 permissions. I've read the mentioned page, and played around with the ideas on it, but haven't gotten things to work. Anyone have any clue to ship my way? -- Michael Welsh Duggan (md5i(a)md5i.com)

[Dovecot] Upgrading to dovecot2 broke IDLE on one mailer, but not another
by John Stracke 29 Jul '13

29 Jul '13

Last weekend I upgraded my server (complete reinstall, actually), from Debian sarge to wheezy, which brought me from dovecot 1.x (I think) to 2.1.7. It's all working now, *except* that the MUA I use on Android, Kaiten (a fork of K-9), apparently no longer gets IDLE notifications. Before the upgrade, when mail arrived, Kaiten would pop up an Android notification immediately; now, it never does (or it might, hours later, with all the messages it notices at that time--presumably this happens when its background service gets killed off and restarted). The weird thing is that IDLE still works flawlessly with Thunderbird, which suggests this is a protocol interaction between Dovecot 2 and Kaiten. (I plan to check with the Kaiten folks next.)

[Dovecot] how to setup different quota for multiple namespaces
by Andreas Oster 29 Jul '13

29 Jul '13

Hello all, I am using dovecot for some time now but always had very basic configurations. I recently have configured a new, additional namespace in order to move archived mails (Thunderbird Archives) to another storage system. namespace { type = private separator = . prefix = Archives. location = maildir:/var/vmail/archive/%Ln/Maildir subscriptions = yes list = children inbox = no } This works well but unfortunately I cannot find a solution to either ignore this new namespace from quota computation or add a separate quota value for it. I have integrated user authentication with LDAP and fetch some user attributes from LDAP entries: user_attrs = =home=/var/vmail/%Ln/Maildir,=mail=maildir:/var/vmail/%Ln/Maildir/,otherPager=quota_rule=*:storage=%$ I configured the quota plugin in the following way: plugin { quota = maildir:User quota:ns= quota2 = maildir:Archive quota:ns=Archives. quota_rule = *:storage=1G quota_rule2 = ns=Archives.:ignore } unfortunately this does not give the desired result. Folders under the Archives namespace use the same quota as INBOX. Does anyone have an idea how to fix this ? Thank you for your kind help Andreas

[Dovecot] Please help with : undefined symbol: mail_deliver_save_open

Greetings dovecot-mailing list! after upgrading from debian squeeze -> debian wheezy and therefore making the big dovecot jump from 1.x to 2.x we are stuck with one final(?) error that we can't get fixed. During login attempts the following is written to the logfiles. Error: dovecot: imap: Error: dlopen(/usr/lib/dovecot/modules/lib90_sieve_plugin.so) failed: /usr/lib/dovecot/libdovecot-sieve.so.0: undefined symbol: mail_deliver_save_open Searching the mailinglist and google in general the only thing i could find was that this error could be connected to loading the sieve plugin outside of lda.

[Dovecot] Case-insensitive "detail" mailboxes?
by /dev/rob0 27 Jul '13

27 Jul '13

We're using sieve with LMTP. We want to have lda_mailbox_autocreate and lmtp_save_to_detail_mailbox. Is there a way to make the "detail" case-insensitive? If so I have not found it yet. I suppose we could lowercase the input string for the SQL userdb query, but that's not what is wanted. The idea being that if a user makes a mailbox called "Test" is that user+test(a)example.com and user+TEST(a)example.com should both go to that "Test" mailbox. If it was lowercased, a mailbox called "Test" would be ignored and "test" used. With autocreate, this could be a problem if mail is delivered to autocreated case-sensitive mailboxes that the user won't see. Hmmm, maybe a global sieve script? -- http://rob0.nodns4.us/ -- system administration and consulting Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:

[Dovecot] dbus support in dovecot?
by Gene Heskett 27 Jul '13

27 Jul '13

Greetings; I am trying to transition from ubu10.04.4 LTS to ubu12.04.2 LTS, but in the changeover I want to setup dovecot as a local only imap server so that I can read & respond to email from any of the other 4 or so machines on my local net. To that end, and given that I have a well working setup right now, using fetchmail driving mailfilter as a pre-check, procmail as the MTA delivering to /var/spool/mail/me, with clamav and spamd in the mix to intercept and send to /dev/null the worst of the spam, or to a quarantine file if clamav triggers. The current transfer mechanism is driven by a script that uses inotifywait to detect newly delivered mail in that directory, and which then sends kmail a dbus message to go get the mail. Since I want to insert dovecot into this chain, does dovecot have a dbus port, and if so, what is the format of the command it expects? Thanks all.

[Dovecot] Namespace, Sieve and upgrading to dovecot 2.0 -- no folder "INBOX/"
by Ben 27 Jul '13

27 Jul '13

I just upgraded from debian squeeze->wheezy. This meant upgrading from dovecot 1.2 to 2.1.7 and upgrading to Pigdeonhole sieve. I have dovecot configured to use sieve and virtual users (I'll post config below) Now any message that come in get filtered by sieve, but any messages that don't hit any filters gives the error (in the sieve log): msgid=<XXXX(a)XXX.com>: failed to store into mailbox 'INBOX/': Invalid mailbox name As far as I can tell, Pidgeonhole has hard-coded to the behavior of 'keep' (that is unfiltered emails) to be: fileinto "INBOX/" However, in my setup "INBOX/" is not a valid folder. "INBOX" is. Is there a way to get pidgeonhole sieve to treat 'keep' as fileinto "INBOX"? Or do I need to reconfigure my dovecot namespaces? I tried playing with them, but everything works right now (sharing, etc) and when I changed my prefix on the inbox, etc, it did weird things (INBOX.INBOX.FOLDER) instead of (INBOX.Folder). Suggestions? Here is, I believe the relevant config info: dovecot.conf: namespace { inbox = yes location = prefix = separator = / type = private } namespace { list = children location = maildir:/Mail/Users/%%n/:INDEX=/Mail/Users/%u/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } Thanks, Ben

[Dovecot] dovecot-lda not logging if dovecot runs under daemontools
by Roberto Puzzanghera 26 Jul '13

26 Jul '13

Hello all, I have dovecot running under daemontools and I can't see dovecot-lda in action when I read the logs. I've set the logs to /dev/stderr because daemontools redirects /dev/stderr to /var/log/dovecot/current. The dovecot server works fine and I know that dovecot-lda is actually doing the delivery, because the sieve facility is working as well. I can get lda log working -but only on syslog- if I override the log_path in this way: protocol lda { mail_plugins = $mail_plugins sieve log_path = } I'm calling dovecot-lda in the usual qmail way. This is my .qmail-default: |/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d $EXT@$USER As running dovecot under daemontools seems to be a common practice among qmail users, could any of you give me an hint on how dovecot should be configured to achieve the purpose?

[Dovecot] Managing IMAP IDLE/Push with Sieve – possible?
by FF 25 Jul '13

25 Jul '13

Hello, I've been using Dovecot with Sieve for a long time already, and I'm very happy with it. Push is working fine too. I was wondering, however, whether it would be possible to define a Sieve rule (perhaps using some plug-in), such that an IMAP push message gets sent out only for specific senders etc.? Have you come across anything like that? Thanks a lot, F.F.
