[Dovecot] DH parameter length too small?
by Jörg Lübbert 02 Nov '13

02 Nov '13

Hello, from my understanding, using 1024bit DH parameters results in a not sufficiently secure key exchange for DH(E). Therefore I think it would be advisable to have parameters of at least 2048bit . In fact, I would see a great benefit in chosing parameter length arbitrarily. I also do not see the benefit of parameter regeneration. What were the design goals here? Thanks, Jörg Lübbert

[Dovecot] Pre imap-session scripting
by azurIt 02 Nov '13

02 Nov '13

Hi, is it possible to run a script right after the IMAP/POP3 session was started? I know about post-login scripting but this is probably not what i'm looking for. I need to run a script which will know PID of process running IMAP session (so it must be already started). Thank you. azur

[Dovecot] Broken files?
by LuKreme 02 Nov '13

02 Nov '13

Getting a lot of these error for two specific mailboxes. They repeat many times a day, usually within less than 5 minutes. mail dovecot: imap(kremels): Error: Broken file /home/kremels/Maildir/.zz.x-tech.2010/dovecot-uidlist line 2: Invalid extended fields: : $ cat .zz.x-tech.2010/dovecot-uidlist 3 V1263241007 N56581 G11fe2118db236952f984010021d1a38d OI tried deleting the files that generated the errors, but they were recreated and the errors returned. (I’m using dovecot2 and Maildir) -- Death was familiar with the concept of the eternal, ever-renewed hero, the champion with a thousand faces. He'd refrained from commenting.

Maybe it will start working if you configure Mutt set spoolfile=imap://steve@vmail-s/ (Just guessing -- I don't use Mutt.) Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Shared namespace, separator, username and dots.
by Marcio Merlone 02 Nov '13

02 Nov '13

Hi folks, I run a legacy mailserver that i had replaced courier-imap for dovecot 1.2. Everything is fine except for shared namespace. Maildir structure has been created using dot '.' as folder separator. It happens that all our users are created as name.surname as default. So when I want to select a shared folder, MUA end up with the following IMAP command: select shared.jhon.doe.folder.subfolder Obviously I took ages to figure why it won't work since it takes 'doe' as a folder and not a username part. When sharing a folder from 'sales' user, for example, it works fine. What do you suggest to make shared folders work for all without rebuilding hundreds of maildirs to change folder separator from '.' to '/'? Thanks for any hint. # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-52-server x86_64 Ubuntu 10.04.4 LTS log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps managesieve ssl_listen: * disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login login_process_per_connection: no login_max_processes_count: 1024 max_mail_processes: 1024 mail_max_userip_connections(default): 20 mail_max_userip_connections(imap): 20 mail_max_userip_connections(managesieve): 10 first_valid_gid: 0 mail_privileged_group: mail mail_location: maildir:~/Maildir:INDEX=/var/cache/dovecot/%n fsync_disable: yes maildir_very_dirty_syncs: yes mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota acl imap_acl mail_plugins(imap): quota imap_quota acl imap_acl mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve namespace: type: private separator: . inbox: yes list: yes subscriptions: yes namespace: type: shared separator: . prefix: shared.%%u. location: maildir:%%h/Maildir:INDEX=%u/Maildir/shared/%%u list: children subscriptions: yes lda: postmaster_address: postmaster(a)a1.ind.br mail_plugins: quota sieve acl quota_full_tempfail: yes auth_socket_path: /var/run/dovecot/auth-master fsync_disable: no auth default: mechanisms: plain login master_user_separator: * passdb: driver: pam args: session=yes blocking=yes dovecot passdb: driver: passwd-file args: /etc/dovecot/passwd.masterusers pass: yes master: yes userdb: driver: nss args: service=ldap blocking=yes socket: type: listen client: path: /var/spool/postfix/private/dovecot mode: 436 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 438 plugin: sieve: ~/.dovecot.sieve acl: vfile acl_shared_dict: proxy::acl dict: acl: mysql:/etc/dovecot/acl-dict-sql.conf -- *Marcio Merlone* TI - Administrador de redes *A1 Engenharia - Unidade Corporativa* Fone: +55 41 3616-3797 Cel: +55 41 9689-0036 http://www.a1.ind.br/ <http://www.a1.ind.br>

[Dovecot] doveadm can't import his own mdboxes

We're running Dovecot 2.1.17 on Debian: # 2.1.17 (9efbc0731929): /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-042stab078.27.debug i686 Debian 7.1 simfs and we're having this namespace configuration: mail_location = mdbox:/var/mail/%Ld/%Ln/mdbox namespace inbox { disabled = no hidden = no ignore_on_failure = no inbox = yes list = yes location = prefix = separator = . subscriptions = yes type = private } As you can see, our namespace seperator is "." and not "/": a LIST "" "*" * LIST (\HasChildren) "." INBOX.test * LIST (\HasNoChildren) "." INBOX.test.huhu * LIST (\HasNoChildren \Trash) "." Trash * LIST (\HasChildren) "." INBOX a OK List completed.

[Dovecot] Configuring SPECIAL-USE Dovecot 2.0.9
by Keith Mountifield 01 Nov '13

01 Nov '13

Hi All, I'm trying to configure Dovecot 2.0.9 to support Outlook 2013. As I understand it, I need to configure XLIST. I have added imap_capability = +XLIST to 20-imap.conf When I try to query the IMAP folders I get an error "An IMAP command Failed". Looking at the logs I get XLIST Command not found. I can only assume that I'm missing something in the configuration. Any help would be greatly appreciated Thanks Keith

[Dovecot] init script as provided http://wiki2.dovecot.org/DovecotInit
by Jess Portnoy 01 Nov '13

01 Nov '13

Hello list, I would add: # dovecot Startup script for the dovecot server # # chkconfig: - # processname: dovecot # config: /path/to/config # pidfile: /path/to/pid So that it supports the chkconfig used by RHEL and clones too. Also, maybe it should be installed by the Makefile's install target? it could then also set: DAEMON=/path/to/dovecot/daemon instead of: DAEMON=/usr/local/sbin/dovecot Cause naturally, it will know the prefix chosen. May the source be with you, Jess Portnoy

[Dovecot] Logging in to a virtual users Maildir
by Steve Downes 01 Nov '13

01 Nov '13

Trying to set up a mailserver to run exim4, dovecot2, (clamav procmail or similar not yet installed) on a virtual machine & access it from various hosts mostly using Mutt. So far no attempt at encryption although there are some pem files from a previous attempt & some evidence from the mutt debug file they may be being used . So far I have attempted to set up dovecot to by accessed by MUAs only & tried to access it from Mutt on on the mailserver virtual machine & on another on locally networked machine (no networking problems). When I open a local mutt I get the following:- 1) could not connect to vmail-s (connection refused) (vmail-s is the mailserver host) 2) mutt then opens, with a blank message screen 3) from mutt I then put C (open mailbox ? for list) & ?. 4) I then get a file list for the mailbox including all dovecot files but no mailbox files except cur. new, & tmp 5) if enter on ../ I get (presumably) /home/vmail/users/steve/ showing Maildir as the 2nd line 6) select Maildir gives me my inbox but continuing the process does not give me acces to any other folders. The files in my mailbox are from my previous version of Dovecot (V1*) but I have previously tried to start anew set of mailboxes with similar results. I enclose below:- my Dovecot.conf file My muttrc file a .muttdebug0 file Dovecot log files show nothing but Dovecot stop/start lines. Any pointers please?

[Dovecot] IMAP Dovecot unknown namespace creating root folders
by marcus lively 31 Oct '13

31 Oct '13

Hi, I hope someone can point me in the right direction here. I am migrating a mailbox from a non cPanel server, and the mailboxes have folders which seem to be at the same level as the Inbox. The users access these mailboxes using IMAP. The new server configuration is Exim > Dovecot 1.2.17 > Maildir with the standard cPanel install settings. dovecot -n output below I have created the new mailbox within cPanel however when I try to create a 'top level' folder in Outlook I receive the error 'Cannot create the folder: Unknown namespace' (Note I also tried this with the windows mail client to ensure it was not client side) I know that I can get round this by setting the root folder path on the client to 'Inbox' and therefore the folders would be created as sub-folders of Inbox, and this would not be visible to the user, but I was hoping to migrate without touching the clients. Should dovecot report the default root folder path automatically, or create a default top level namespace for each user so this can be done, or could I have just gone wrong and missed something. Any advice on getting this working appreciated, thanks for any help Maspry # 1.2.17: /etc/dovecot.conf # OS: Linux 2.6.32-71.el6.x86_64 x86_64 CentOS release 6.4 (Final) protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/dovecot/ssl/dovecot.crt ssl_key_file: /etc/dovecot/ssl/dovecot.key ssl_cipher_list: ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_process_per_connection: no login_processes_count: 2 login_max_processes_count: 50 login_max_connections: 500 mail_max_userip_connections(default): 20 mail_max_userip_connections(imap): 20 mail_max_userip_connections(pop3): 3 maildir_copy_preserve_filename: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): acl quota imap_quota mail_plugins(imap): acl quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): UID%u-%v pop3_logout_format(default): top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_logout_format(imap): top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_logout_format(pop3): top=%t/%p, retr=%r/%b, del=%d/%m, size=%s, bytes=%i/%o namespace: type: private prefix: INBOX. inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)example.com auth default: mechanisms: plain login cache_size: 1024 username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!#$-=?^_{}~./@+% passdb: driver: checkpassword args: /usr/local/cpanel/bin/dovecot-auth userdb: driver: prefetch socket: type: listen client: path: /var/run/dovecot/auth-client mode: 438 plugin: quota: maildir quota_rule: Trash:ignore acl: vfile

Re: [Dovecot] Encryption solution for messages at rest
by Douglas Mortensen 30 Oct '13

Currently our dovecot servers are on our webhosting linux boxes. We are using the LAMP stack to host websites, and also doing email with postfix & dovecot on these systems. We provide this as a hosting setup for 100+ accounts/websites on a single server (a multi-tenant setup). Each customer has anywhere between 1-100 email accounts which Dovecot services. If a customer has vulnerable PHP code on a website, some of these will allow a remote file upload. I have seen cases where they upload a PHP script that is a sort of web-based console/shell to the server (file-system, etc.). It provides several tools which all run through the uploaded PHP script to try to brute force and do other attacks. I've seen attempts at a root exploit. We've never had a root exploit and any such case of a customer's site being hacked has been easily contained by simple filesystem permissions being correct (and the fact that we have apache setup to run all scripts as the user who is the owner of the script files, which confines the script to that users' permissions). Still nobody loves the idea of bad guys trying to hack on your box. So.... given that type of scenario, if filesystem permissions weren't correct, or some new exploit surfaced that allowed someone bypass or elevate to root, then they could theoretically have access to the entire fileystem including where emails are stored. I hope to never have this sort of thing happen. We patch our systems regularly and have other security measures we follow to prevent this. We also are managing most of the PHP scripts customers use ourselves now and are updating those for the CMS' and other systems proactively. However, it would be nice to know that even if we were breached, the emails on the server were encrypted and would be completely useless to an attacker. This type of encryption is ideal and some regulations prefer (although don't require) it. - Doug Mortensen Network Consultant Impala Networks P: 505.327.7300 -----Original Message----- From: dovecot-bounces(a)dovecot.org [mailto:dovecot-bounces@dovecot.org] On Behalf Of Michael Orlitzky Sent: Monday, October 28, 2013 11:52 AM To: dovecot Subject: Re: [Dovecot] Encryption solution for messages at rest On 10/28/2013 12:02 PM, Douglas Mortensen wrote: > Hi, > > We have clients with various security & compliance requirements. > Although not required, it would be ideal to have messages encrypted at > rest. You can rule out a lot of the crazier options by answering the questions, (a) What attack scenario do you have in mind? (b) How will encryption help?

[Dovecot] Right values for Antispam plugin
by Michael Neurohr 30 Oct '13

30 Oct '13

Hi! I'm currently configuring the Dovecot Antispam plugin for the use with Dspam. In general it works, but I'm not sure about one special config parameter: antispam_dspam_args At the moment I set it to: antispam_dspam_args = --source=error;--signature=%%s;--user;%u Is that the appropriate value for retraining? I'm not sure if "%%s" is correct to get the signature value. I was not able to find any documentation that describes that value. So I just want to know if my plugin config is correct for retraining. plugin { antispam_backend = dspam antispam_spam = Spam antispam_trash = trash;Trash;Deleted Items;Deleted Messages antispam_signature = X-DSPAM-Signature antispam_signature_missing = move antispam_dspam_binary = /usr/bin/dspam antispam_dspam_args = --source=error;--signature=%%s;--user;%u } Thanks, Michael

Hi to all. Is it possible to disable unsecure POP3 protocol at all in Dovecot 2.1? There was "protocols" option in 1.x version, and there was separate pop3 and pop3s modules. There is no "pop3s" in configuration files in 2.1.

[Dovecot] Problem with dovecot-lda
by Wolfgang Ganzert 29 Oct '13

29 Oct '13

Hello Ladies and Gentlemen, first of all I have to say that dovecot is really impressive. I seems to be a very goot IMAP server and has in general a good documentation. I'm a beginner regarding the administration so please excuse if my questions sound silly but I want to learn to administrate these sophisticated things. Now here's my configuration: Linux openSuSE 12.1 Postfix 2.8.8 Dovecot 2.0.16 Boundary condition: Postfix as smtp (Postfix is configured as relay server; mail is sent to smtp.web.de if mail is not locally distributed) Dovecot as IMAP server in my private network (192.168....) Situation: I want to store outgoing mail which is send by postfix also in a "SENT" folder in Dovecot. The SENT folder is available and created through the plugin "autocreate". The main.cf file from postfix contains the following mailbox command: mailbox_command = /usr/lib/dovecot/dovecot-lda -f "$SENDER" -a "$RECIPIENT" -m SENT If I send a simple mail from the shell with the following command echo "Hello me" | mail -s "Dovecot test 50, shell nach SENT" $USER the mail is send to my mailbox and stored in the folder "SENT" as unread. Problem: 1. I would expect to have to mails coming in; one in my "SENT" folder because this is copy of the mail and another one which is the incoming folder because the mail was sent to me. But, there is no mail in the incoming folder. 2. If I use a mail client like kmail2 the same thing happens. The mail is distributed to the SENT folder but there's no copy in the incoming folder. 3. If I send a mail to my adress at @web.de with the postfix configuration from above I do not receive the mail at web.de. 4. If I send a mail to my adress at @web.de with a postfix simplified mailbox command NOT containing the mailbox with "-m", then mail is send to web.de and there I receive it in the incoming box. This is the simplified command: mailbox_command = /usr/lib/dovecot/dovecot-lda -f "$SENDER" -a "$RECIPIENT" Summary: All examples from above show that I do not get a COPY of the outgoing mail in my "SENT" folder but it's the REAL mail. Can You please give me some advice what to do? Thank You! Wolfgang P.S.: In /var/log/mail and /var/log/dovecot.log I do not get any errors.

[Dovecot] Building the Antispam plugin fails
by Michael Neurohr 29 Oct '13

29 Oct '13

Hi! I'm running Dovecot 2.2.5 on a CentOS 6.4 server from the ATRPMs repository. Unfortunately this repo does not provide a packaged version of the Antispam Plugin. So I followed the steps outlined in the Dovecot Wiki [1]. But when running the command ./configure, I get stuck with the following error: checking for dovecot-config in "/usr/local/lib/dovecot"... not found configure: configure: Use --with-dovecot=DIR to provide the path to the dovecot-config file. configure: error: dovecot-config not found So I downloaded the dovecot-devel package and run the configure command again with the following command: ./configure --with-dovecot=/usr/include/dovecot but with the same result. I made sure the the directory "/usr/include/dovecot" does contain the Dovecot header files. What can I do next? Do I really also have to install Dovecot from the sources only to get the Antispam Plugin working? Thanks, Michael [1] http://wiki2.dovecot.org/Plugins/Antispam

[Dovecot] recipient_delimiter deux
by LuKreme 29 Oct '13

29 Oct '13

OK, I've been banging my head on why my procmail setup for virtual users is no longer working (difficult to test, since enabling it breaks live user's mail). There are only a few virtual users who have any sort of filters in place anyway (the heavy procmail users are local, not virtual), and they are fairly simple, so I think I can recreate them with sieve. I think I have everything I need for sieve to work, but now what? The first thing I want to do is have sieve process recipient_delimiter into a separate mailbox (creating it, if needed). Googling just for example sieve scripts comes up empty (well, directing to the dovecot wiki which at least on the links that come up, does not have sample scripts). so, foo+bar(a)example.com will go into foo's mailstore in the folder .bar/new/ On 27 Sep 2013, at 00:24 , Steffen Kaiser <skdovecot(a)smail.inf.fh-brs.de> wrote: > Dovecot LDA uses the "-m" option and only lda_mailbox_autocreate and lda_mailbox_autosubscribe, no need for recipient_delimiter to override the default mailbox. Which I still don't understand. recipient_delimiter = + is the default, so I shouldn't need to set it in my confs, I just need to setup a sieve recipe (is that what it is called? script?) that will process these messages, right? What would that look like? I have to setup the SQL users so that LMTP or LDA is used for deliver, but I want that to apply only to the sql users. Something like this, maybe? userdb { args = /etc/dovecot/dovecot-sql.conf.ext default_fields = uid=vpopmail gid=vchkpw mail_location=/usr/local/virtual/%u mail=maildir:/usr/local/virtual/%u sieve=/var/sieve/%u.sieve protocol_lda=$mailplugins sieve driver = sql } I'm sure that protoco_lda isn't the right syntax though. If I set sieve=/var/sieve/%u.sieve as above would users still be able to use sieve-manage to manage their own sieve files? And what MUAs support this? If I left that out, do I put ~/.dovecot.sieve in with the other mailboxes and {cur,new,tmp} and the index files, or will there be issues? If I put a dovecot.sieve file there will it just be seen, processed, and work?

[Dovecot] Dovecot replication - I'm stuck
by IT geek 31 28 Oct '13

28 Oct '13

Hi, I've been following the wiki document at http://wiki2.dovecot.org/Replication, but I've become stuck. I'm running version 2.1.3 on NetBSD 5.2 (v2.2+ isn't available as a package yet, and compiling my own is well outside my wheelhouse). I have a couple of questions: The wiki page keeps referring to "vmail". Is this a just system user I need to create? Presumably on both Dovecot boxes? If I don't use virtual users, do I need this? Here is my dovecot -n: # 2.1.3: /usr/pkg/etc/dovecot/dovecot.conf # OS: NetBSD 5.2 cobalt auth_mechanisms = plain login dsync_remote_cmd = ssh -l%{login} %{host} doveadm dsync-server -u%u listen = 192.168.1.1 login_greeting = Go on then, let's have it... mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_plugins = " notify replication" passdb { driver = passwd } plugin { mail_replica = remote:vmail@server2.mydomain.com replication_full_sync_interval = 1 hours } protocols = imap service aggregator { fifo_listener replication-notify-fifo { user = vmail } unix_listener replication-notify { user = vmail } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } service imap-login { inet_listener imap { port = 0 } } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0600 } } ssl_cert = </etc/openssl/certs/mail.mydomain.com.crt ssl_key = </etc/openssl/private/mail.mydomain.com.key userdb { driver = passwd } protocol lda { postmaster_address = postmaster(a)mydomain.com } Any help would be greatly appreciated, as I'd really love to get this working. Thanks, -Mark

Re: [Dovecot] Dbox group file permissions
by Chris Lasater 28 Oct '13

28 Oct '13

Just in case someone else has the same problem, I had to change the following two variables mail_home = /mnt/home/imapd/%d/%n mail_location = dbox:/mnt/home/imapd/%d/%n to mail_home = /mnt/home/imapd/%d/%n mail_location = dbox:~/ "When mail_location begins with%h or~/, its permissions are copied from the first existing parent directory if it has setgid-bit set. This isn't done when the path contains any other %variables."

[Dovecot] Blocking certain hostnames/clients
by Charles Marcus 28 Oct '13

28 Oct '13

Hello, As a result of learning of the new 'Intro' App introduced by LinkedIn, and discussing how to block SMTP access to my postfix server from these clients, I'm now interested in doing the same for dovecot. Bottom line desire is to avoid scraping/hijacking email stored on my dovecot server by any client other than a users client. This includes Intro (so, LinkedIn), Blackberry, GMail, Outlook, etc. The boss has expressed the desire to NOT block all email from them, just disallow any of their clients from AUTH'ing (either SMTP or IMAP/POP). I'd be interested if anyone has any kind of database of hostnames/IP blocks of the freemailers out there that support adding 3rd party accounts, especially ones supporting IMAP. Anyway, article raising the concern found here: http://www.bishopfox.com/blog/2013/10/linkedin-intro/ "LinkedIn released a new product today called Intro. They call it ?doing the impossible?, but some might call it ?hijacking email?. Why do we say this? Consider the following: Intro reconfigures your iOS device (e.g. iPhone, iPad) so that all of your emails go through LinkedIn?s servers. You read that right. Once you install the Intro app, all of your emails, both sent and received, are transmitted via LinkedIn?s servers. LinkedIn is forcing all your IMAP and SMTP data through their own servers and then analyzing and scraping your emails for data pertaining to?whatever they feel like." -- Best regards, */Charles/*

[Dovecot] Which MTA for a personal-use dovecot instance?
by Dan Langille 27 Oct '13

27 Oct '13

I'm planning to deploy a personal dovecot IMAP server (i.e. I am the only user) in a FreeBSD jail. At present, I have IMAP deployed on the same host as one of my mail servers, which is running Postfix. I do like Postfix, but it seems to be a bit overkill for this particular situation. All my incoming MX are provided by Google. They handle the incoming mail and forward to my private MX, and from there the mail for me goes into my ~/Maildir. With the move to IMAP in a jail, I need to get the mail from my private MX into that jail. All mail being sent to that jail will be destined for my ~/Maildir, with some massaging via procmail. Given that I've just started using mail/nullmailer, I was wondering if there was something simple that I could use. I was planning to use postfix, require TLS, lock things down tightly. But I'm open to suggestions for something simple. -- Dan Langille - http://langille.org/

[Dovecot] Dovecot proxy hooks
by dac＠getodata.ro 26 Oct '13

26 Oct '13

I am interested in the possibility of using Dovecot IMAP/POP proxying capabilities to analyze emails that are passing through and possibly modify content on the fly. This subject has been discussed here [1] before. I have tried the mail-filter plugin [2], but the hooks it uses are only called in a non-proxy setup. Is there a practical way of doing this, or plans to add such a feature?

[Dovecot] Plugin issue with update from 2.0.19 to 2.1.17
by Reinaldo Matukuma 26 Oct '13

26 Oct '13

Hello. Probably only Timo can help-me with this. I have a self-made plugin based on the zlib plugin that i use to cryptograph the messages at inbox. As a side-effect of the cryptography, my plugin changes the size of the message, but until 2.0.19 this works well with dovecot index and the W/S flags. But now, i'm going to upgrade to 2.1.17 and now i have these messages on log at my test ambiance: Oct 15 20:19:25 test dovecot: imap(reinaldo(a)exemplo.com.br): Error: Cached message size smaller than expected (367 < 529) Oct 15 20:19:25 test dovecot: imap(reinaldo(a)exemplo.com.br): Error: Maildir filename has wrong S value, renamed the file from /storage/test/messages/exemplo.com.br/reinaldo/Maildir/.Sent/cur/1381879158.M634385P5208.test,S=367,W=378:2,S to /storage/test/messages/exemplo.com.br/reinaldo/Maildir/.Sent/cur/1381879158.M634385P5208.test,S=529:2,S Oct 15 20:19:25 test dovecot: imap(reinaldo(a)exemplo.com.br): Error: Corrupted index cache file /storage/test/messages/exemplo.com.br/reinaldo/Maildir/.Sent/dovecot.index.cache: Broken physical size for mail UID 6 I understood with these messages that the dovecot is arguing to get the real size of the file now, overriding the return of size from my crypto plugin. But i don't understood if this is a consequence from the changes to correct the index issue (the dovecot.index.cache issue). So... I want know if the correct way to fix this would be change my plugin to return the real size of the file (that will be larger than the effective message that the plugin returne after the de-cryptography) or if i need use some new function to the plugin replace the expected size based on the real size of the message, not of the file. Thanks Reinaldo

Using Dovecot v2.2.5.4; I see: # doveadm -v -o imapc_user=user(a)example.com -o imapc_password=password -o imapc_host=imap.example.com -o imapc_port=993 -o imapc_ssl=imaps -o imapc_ssl_dir=/etc/ssl -o imapc_feature=rfc822.size -o imapc_ssl_verify=no sync -1 -R -u user(a)example.com imapc: dsync(user(a)example.com): Info: copy from Drafts: box=Drafts, uid=8343, msgid=<4F387A25.5010900(a)example.com>, size=2954969 dsync(user(a)example.com): Info: copy from Drafts: box=Drafts, uid=8344, msgid=<5237B0BF.7030402(a)example.com>, size=3371710 dsync(user(a)example.com): Info: copy from Drafts: box=Drafts, uid=8345, msgid=<5237B588.6040009(a)example.com>, size=3266 dsync(user(a)example.com): Info: copy from Drafts: box=Drafts, uid=8346, msgid=<5237B6B4.2030203(a)example.com>, size=4201 dsync(user(a)example.com): Info: copy from Drafts: box=Drafts, uid=8347, msgid=<5237B888.7030807(a)example.com>, size=3371445 dsync(user(a)example.com): Info: copy from Drafts: box=Drafts, uid=8348, msgid=<5237C224.9010608(a)example.com>, size=3371745 dsync(user(a)example.com): Info: copy from Drafts: box=Drafts, uid=8349, msgid=<5237C350.5080608(a)example.com>, size=3371700 dsync(user(a)example.com): Info: copy from Drafts: box=Drafts, uid=8350, msgid=<5237C5EE.5030408(a)example.com>, size=3371619 dsync(user(a)example.com): Info: expunge: box=Drafts, uid=8209, msgid=< 4F387A25.5010900(a)example.com>, size=2954969 The interesting lines being uid=8209 and uid=8343; why would dsync both copy and then expunge the same message from the same mailbox?

[Dovecot] Strange output from LIST command
by azurIt 26 Oct '13

26 Oct '13

Hi, i'm using Dovecot 2.1.7 (Debian Wheezy) and output from LIST command looks strange: C: 4 LIST () "" (INBOX INBOX.Karantena INBOX.Spam) RETURN (STATUS (UNSEEN)) S: * LIST () "." "INBOX" S: * LIST () "." "INBOX.Karantena" S: * STATUS "INBOX.Karantena" (UNSEEN 0) S: * LIST () "." "INBOX.Spam" S: * STATUS "INBOX.Spam" (UNSEEN 0) S: 4 OK List completed. The UNSEEN information for INBOX is completely missing. It is correct behavior? If not, is this a known bug in 2.1.7? Thank you. azur

[Dovecot] Login into other user's account // master user for non-master users // chroot to users.<user>
by Steffen Kaiser 26 Oct '13

26 Oct '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Currently some of our organizational roles uses shared secrets (aka the password) to access the mail account of an organizational role, say "sales" for example. For one, I don't like shared secrets, for second, there had been some changes to shared mailboxes, I can only say "user sales has deleted the message at then and then". Therefore I would like to access the mailboxes of organizational roles with the accounts of the humans performing the role currently. Using sharing and ACLs it is possible to map the mailboxes of "sales" to "users.sales" namespace for specific other users, actually the human ones, say userA and userB for example. However, userB does not like managing identities in its MUA and refuses to acknowledge the messages in users.sales for various reasons. One reason was that userB wants to visibly separate strictly both mail accounts, the private messages in "userB" and the role's ones in "sales". Now, I came into thinking that it would be good in such case, if userB could authentificate as, say "sales*userB" - much like a master user - and ends in "sales"'s home, but with access permissions of "userB", well, like a chroot. Would it be an interesting feature to add to Dovecot's core? If I simulate "sales*userB" with password of userB and let the userdb return the home of sales, userB would gain "owner" privilegues of sales implicitly. So there seems to exist no workaround.

[Dovecot] LMTP, TLS/SSL, authentication, proxy
by Jogi Hofmüller 26 Oct '13

26 Oct '13

Folks, Several questions packed into one email ;) Can dovecot use TLS/SSL on LTMP inet socket? Can I configure dovecot to only let an authenticated user deliver mail via LMTP? Can I tell dovecot to use a user/password for proxying LMTP connections? All this is related to my quest to move from cyrus to dovecot transparently to our users. And if any of the above questions can be answered with yes, I would appreciate the odd hint on howto configure that :) Thanks in advance! -- j.hofmüller aka Thesix http://users.mur.at/thesix/

[Dovecot] Empty Mails from MAILER-DAEMON with Dovecot-Antispam and DSPAM
by Anna Christina Naß 26 Oct '13

26 Oct '13

Hallo, I've installed the dovecot-Antispam extension to my dovecot IMAP installation in conjunction with DSPAM. But when moving Mails from e.g. INBOX to Spam or vice versa, empty mails from MAILER-DAEMON appear after the original mail has been moved. This happens using Thunderbird 17esr, K-9 Mail on Android and Apple Mail (Mountain Lion). (Perhaps also when using a Webmail IMAP client) The source from one of these empty mails looks like this: ----snip---- Return-Path: <MAILER-DAEMON> X-Original-To: acn Delivered-To: acn(a)mydomain.name Received: from localhost (localhost.localdomain [127.0.0.1]) by <my host name> (Postfix) with SMTP id CB81B140011 for <acn>; Thu, 24 Oct 2013 09:23:33 +0200 (CEST) X-DSPAM-Reclassified: Spam Message-Id: <20131024072333.CB81B140011@<my host name>> Date: Thu, 24 Oct 2013 09:23:33 +0200 (CEST) From: MAILER-DAEMON ----/snip---- Do you have any idea why these mails appear and how I can prevent it?

[Dovecot] UIDL conversion courier -> dovecot
by Will Yardley 25 Oct '13

25 Oct '13

I've got a weird split setup where POP3 is currently handled by Courier (courier-imap-3.0.2 distribution), and IMAP is currently handled by the RHEL 5 version of Dovecot (1.0.7) I'm trying to figure out a way to convert the POP3 UIDLs (in cases where the courierpop3dsizelist is newer than dovecot-uidlist, at least) to something that Dovecot will read, or to configure Dovecot's pop3 to use a UIDL format that will work, as mentioned in the migration wiki. We have some "squeaky wheel" users who don't have their POP clients set to delete messages, and are likely to complain about re-downloading their several GB of mail. Thus far, the migration scripts haven't seemed to work properly, maybe because of the versions I'm using. I'm not sure whether the Courier versions there refer to Courier MTA version or Courier IMAP version, but adjusting the UIDL format to %v-%u (as suggested for early Courier 3 / Dovecot 1.0) hasn't worked (I saw %u-%v online, but that also didn't work). Since the Courier system doesn't seem to report validity, I also tried just '%u' - this works *if* I delete the header line as well as rename the courierpop3dsizelist to dovecot-uidlist, but I still don't get the exact same UIDLs as before. I'm willing to write my own migration tool, or to adapt the existing one, but I could use some assistance knowing how to do the translation. Dovecot -n for that instance is below, slightly sanitized, obviously I can change pop3_uidl_format; I also tried getting rid of pop3_reuse_xuidl: Basically, to give a concreate example, the Courier system seems to use the filename as the UIDL, with this courierpop3dsizelist: /2 45 1382654636 1199751891.13891_0.water-ox:2,Sa 2412 0:1382654636 1199927364.22870_0.fire-ox:2,S 2440 0:1382654636 1199936486.3332_0.wood-ox:2,Sa 2074 0:1382654636 1199985712.27745_0.water-ox:2,RS 4007 0:1382654636 1199993867.23139_0.fire-ox:2,S 1550 0:1382654636 producing this UIDL output: UIDL +OK 1 1199751891.13891_0.water-ox 2 1199927364.22870_0.fire-ox 3 1199936486.3332_0.wood-ox 4 1199985712.27745_0.water-ox 5 1199993867.23139_0.fire-ox [...] Dovecot's dovecot-uidlist: 3 V1199747645 N606 562 W2412 :1199751891.13891_0.water-ox:2,Sa 563 W2440 :1199927364.22870_0.fire-ox:2,S 564 W2074 :1199936486.3332_0.wood-ox:2,Sa 565 W4007 :1199985712.27745_0.water-ox:2,RS 566 W1550 :1199993867.23139_0.fire-ox:2,S producing: UIDL +OK 1 1199747645-562 2 1199747645-563 3 1199747645-564 4 1199747645-565 5 1199747645-566 (or, if I change the format to just %u): +OK 1 650 2 651 3 652 4 653 5 654 # dovecot --version 1.0.7 # 1.0.7: /etc/dovecot.d/XXX.cfg base_dir: /var/run/dovecot/pop-its syslog_facility: local4 protocols: pop3 pop3s listen: *:110 ssl_listen: *:995 ssl_ca_file: /etc/pki/dovecot/certs/XX.pem ssl_cert_file: /etc/pki/dovecot/certs/XXXX.pem ssl_key_file: /etc/pki/dovecot/private/XXXX.key disable_plaintext_auth: yes login_dir: /var/run/dovecot/pop-its/login login_executable: /usr/libexec/dovecot/pop3-login login_greeting_capability: yes login_processes_count: 4 login_max_processes_count: 512 verbose_proctitle: yes mail_location: maildir:/var/spool/maildir/%1Ln/%Ln:INDEX=/var/spool/dovecot/indexes/%1Ln/%Ln mail_debug: yes mmap_disable: yes maildir_copy_with_hardlinks: yes mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/pop3 pop3_reuse_xuidl: yes pop3_uidl_format: %v-%u pop3_client_workarounds: outlook-no-nuls oe-ns-eoh namespace: type: private separator: . prefix: Mail. inbox: yes auth default: mechanisms: plain login passdb: driver: ldap args: /etc/dovecot.conf-ldap userdb: driver: static args: uid=vmail gid=mail home=/var/spool/maildir/%1Ln/%Ln socket: type: listen master: path: /var/run/dovecot/pop-its/auth-master mode: 384 user: vmail group: mail TIA! /wby

[Dovecot] Replication (Mac OS X)
by Rusty Ross 25 Oct '13

25 Oct '13

Hello, I am taking a stab at setting up dovecot replication between two OS X Mavericks servers. (The dovecot version in Mavericks is 2.2.5.) The first question I have is in regards to userdb. The user accounts are Open Directory based. The output of: doveadm user ‘*' …yields only: # doveadm user ‘*' submit However, specific user accounts can be looked up explicitly, ie: # doveadm user 'mary' field value uid 214 gid 6 home mail maildir:/Library/Server/Mail/Data/mail/10C94BF9-5CC4-4DDB-B0F0-5D23F22B2D9F quota maildir:User quota:noenforcing quota_rule *:storage=0 mail_location maildir:/Library/Server/Mail/Data/mail/10C94BF9-5CC4-4DDB-B0F0-5D23F22B2D9F sieve /Library/Server/Mail/Data/rules/10C94BF9-5CC4-4DDB-B0F0-5D23F22B2D9F/dovecot.sieve sieve_dir /Library/Server/Mail/Data/rules/10C94BF9-5CC4-4DDB-B0F0-5D23F22B2D9F sieve_storage /Library/Server/Mail/Data/rules/10C94BF9-5CC4-4DDB-B0F0-5D23F22B2D9F According to http://wiki2.dovecot.org/Replication, user listing via “doveadm user ‘*’” is required for replication. Any thoughts about how I can get that working (or work around it) in this environment? Thanks, Rusty

[Dovecot] Replication not happening on 2.2
by Lucas Rothamel - Eye Catching Webdesign 24 Oct '13

24 Oct '13

Hello, first - thanks for the help in getting dovecot 2.2 compiled and installed on Debian. I have Dovecot 2.2 running now on two servers, and to test replication, I am polling mail on one server whilst the other creates mail regularly from crontab output. I have replication set up, but nothing at all is appearing on the other server, and I do not have any dsync / doveadm messages in /var/log/mail.log any more. With 2.1, these two used to spam many errors into mail.log. Any hints?

Hello, i want to know if it's possible to use mailbox sharing with mdbox. I have done a setup with maildir where it's working fine but with mdbox I'm only able to subscribe the shared folder but there are no messages in it. (maybe a problem with the namespace) I'm running dovecot 2.2.6 [deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.2.patched main ] on Debian Wheezy Kind regards Stefan

[Dovecot] Odd Feature Request - RBL blacklist lookup to prevent authentication
by Marc Perkel 23 Oct '13

23 Oct '13

I would like to have a list of IPs (hacker list) that I can do a lookup on so that if anyone tries to authenticate to dovecot they always fail if they are on my list. I have the list - and the list is available as a DNS blacklist. I'd like to have it work with both local IP lists or RBL lookup. The idea is so hackers from known IP addresses never succeed. If Dovecot provides the feature I have about 1/2 million IP addresses of known current hackers to block. Anyone else interested in this?

It did not. Any ideas why this is happening?

Surely there is a better way to do this? Looking at the code, it's trying to open the tty and turn off echo. For the record: FreeBSD 8.4-RELEASE-p3 And yes, there is no console.

[Dovecot] Dbox group file permissions
by Chris Lasater 22 Oct '13

22 Oct '13

Hi everyone, I feel like I am missing something obvious here. I have dovecot up and running and every piece of mail is given user read/write permission. I see the option mail_gid, but I do not see anyplace to set the group permissions. I see the below wiki talking about new home directories getting their permission from the parent directory, but this does not seem to work. Any assistance would be appreciated. http://wiki2.dovecot.org/SharedMailboxes/Permissions I changed the group permissions on the parent directory, and used rm -rf to delete the user directories, then logged in again so it was recreated. [user@dovecot ~]$ sudo ls -la /mnt/home/imapd/domain.example.net/ total 24 drwxr-x--- 6 imapd imapd 4096 Oct 21 17:35 . drwxr-xr-x 46 imapd nagios 4096 Oct 21 16:55 .. drwx------ 3 imapd imapd 4096 Oct 21 16:59 user1 drwx------ 3 imapd imapd 4096 Oct 21 17:35 user2 Setup Mail is written in dbox format CentOS 5.9 dovecot 2.2.6 NFS with director Mail Configs mail_home = /mnt/home/imapd/%d/%n mail_location = dbox:/mnt/home/imapd/%d/%n mail_uid = imapd mail_gid = imapd Thanks, Chris

[Dovecot] Mailboxes separated from IMAP server
by Reymer Antonio Vargas Solano 21 Oct '13

21 Oct '13

Hello folks, At my university we are trying to implement a distributed email backend, but I have some troubles, The topology: Server A: Postfix+LMTP # MTA Server B: Dovecot+LMTP # Just mailboxes Server C: Dovecot # POP3/IMAP Right now the Server A can leave a received email to the Server B, but I don't know how to communicate Server C to the Server B to retrieve the emails. I think that we should use IMAP protocol, but I am confused about how to connect them, I don't know if we have to use a proxy IMAP server, or another thing. Can anyone give me an idea? Regards, Reymer Antonio Vargas Solano
