Dovecot Sieve and Postfix header_checks Issue
by Klaipedaville on Google 27 Sep '14

27 Sep '14

Hello List, I tried to subscribe but it's taking forever for the confirmation email to arrive so I thought I would ask away by emailing directly. My apologies in advance should this question appear twice. It may seem real simple to experts but I cannot really figure it out. I'll try to be concise: Dovecot version is 2.1.7. Its dovecot –n is real short one and follows right after my question. I have my Postfix 2.9.6 properties set like this: header_checks = /etc/path/to/myfile. Then I have Dovecot Sieve also configured and working fine. Now the trouble is that these two cannot be combined together can they? Dovecot Sieve and Postfix's header_checks? If I turn off header_checks in Postfix then Dovecot Sieve is working fine. If I vise versa turn off Dovecot Sieve then Postfix's header-checks are also working fine. However, when I keep them both turned on it also works but only partially and in this case Dovecot Sieve never bounces back any rejected massages remotely, the bounce happens only locally. That is I can see it in my logs that it was rejected locally but the message is never sent back to the sender saying something like, "Spam is rejected here". Thus the reject turns into a silent discard without telling the sender anything at all. Any ideas, help, advices how do I fix that? Would be really grateful for any suggestions / assistance at all. Many thanks in advance! P.S. I would like to use both because Dovecot Sieve is a very powerful and great plugin that uses Spamassassin's added tags and headers based on which I create my rules. Postfix in its turn has a very neat feature of checking the headers via regexp but Postfix does not see / detect Spamassassin's added headers at all because I passed delivery and authentication (which is a way better than Postfix's) to dovecot deliver. # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.6 ext4 auth_mechanisms = plain login cram-md5 scram-sha-1 auth_verbose = yes hostname = WindTalker info_log_path = /var/log/dovecot-sieve.log log_path = /var/log/dovecot-sieve-errors.log mail_location = maildir:/home/mvail/%d/%n 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 passdb { args = /etc/dovecot/passwd driver = passwd-file } plugin { sieve = ~/.dovecot.sieve sieve_default = /etc/dovecot/default.sieve sieve_dir = ~/sieve } pop3_uidl_format = %g postmaster_address = postmaster(a)example.com protocols = imap pop3 sieve service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } ssl_ca = </etc/ssl/ca.crt ssl_cert = </etc/ssl//new.crt ssl_key = </etc/ssl/new.key userdb { args = uid=vmail gid=vmail home=/home/vmail/%u driver = static } protocol lda { mail_debug = yes mail_plugins = sieve } Regards, Dennis.

ALT storage question
by Ralf Hildebrandt 27 Sep '14

27 Sep '14

I want to migrate from a non-hashed storage to a hashed storage. So I set this up: mail_location = mdbox:/srv/vmail/%2.256Hu/%Lu/mdbox:ALT=/srv/vmail/%Ld/%Ln/mdbox I rsynced the "old" mdbox-style mailbox from another machine to to /srv/vmail/%Ld/%Ln/mdbox (/srv/vmail/charite.de/ralf.hildebrandt/mdbox in my case) The mail_location /srv/vmail/c5/ralf.hildebrandt(a)charite.de was non-existing. Then I connected using IMAP and tried to have a look at the INBOX: Sep 27 11:15:15 imap(ralf.hildebrandt(a)charite.de): Debug: Effective uid=10000, gid=10000, home=/srv/vmail/c5/ralf.hildebrandt(a)charite.de Sep 27 11:15:15 imap(ralf.hildebrandt(a)charite.de): Debug: Home dir not found: /srv/vmail/c5/ralf.hildebrandt(a)charite.de Sep 27 11:15:15 imap(ralf.hildebrandt(a)charite.de): Debug: Namespace inbox: type=private, prefix=, sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes location=mdbox:/srv/vmail/c5/ralf.hildebrandt@charite.de/mdbox:ALT=/srv/vmail/charite.de/ralf.hildebrandt/mdbox Sep 27 11:15:15 imap(ralf.hildebrandt(a)charite.de): Debug: fs: root=/srv/vmail/c5/ralf.hildebrandt(a)charite.de/mdbox, index=, indexpvt=, control=, inbox=, alt=/srv/vmail/charite.de/ralf.hildebrandt/mdbox Sep 27 11:15:15 imap(ralf.hildebrandt(a)charite.de): Debug: Namespace : /srv/vmail/c5/ralf.hildebrandt(a)charite.de/mdbox doesn't exist yet, using default permissions Sep 27 11:15:15 imap(ralf.hildebrandt(a)charite.de): Debug: Namespace : Using permissions from /srv/vmail/c5/ralf.hildebrandt(a)charite.de/mdbox: mode=0700 gid=default Sep 27 11:15:15 imap(ralf.hildebrandt(a)charite.de): Debug: Namespace : /srv/vmail/c5/ralf.hildebrandt(a)charite.de/mdbox/mailboxes/INBOX doesn't exist yet, using default permissions Sep 27 11:15:15 imap(ralf.hildebrandt(a)charite.de): Debug: Namespace : Using permissions from /srv/vmail/c5/ralf.hildebrandt(a)charite.de/mdbox: mode=0700 gid=default Sep 27 11:15:15 imap(ralf.hildebrandt(a)charite.de): Error: Mailbox INBOX has existing files in alt path, rebuilding storage to avoid losing messages Sep 27 11:15:15 imap(ralf.hildebrandt(a)charite.de): Error: Failed to autocreate mailbox INBOX: Internal error occurred.

Thanks for confirming what I suspected, Timo. The latter, if it is at all feasible, appears to be an "inside job" type of exploit, where the exploiter already has an account but can arbitrarily change their password. It's not as serious as the pre-login one, but worth addressing if the narrow circumstances of using post-login bash scripts apply. Joseph Tam <jtam.home(a)gmail.com>

doveadm penalty: who is 0.0.0.0?
by Peer Heinlein 27 Sep '14

27 Sep '14

Using doveadm penalty I just noticed a penalty for 0.0.0.0. Is this Postfix querying the auth-socket for his SASL-requests? I tried adding 0.0.0.0 to login_trusted_networks, but that doesn't help.

Re: director
by Chris Lasater 26 Sep '14

26 Sep '14

The configuration and run/base_dir directories can be where ever you like. The locations Eduardo stated are the most appropriate for dovecot installed with an RPM. Mine were compiled and set in the home directory, so they are in a slightly different location. As long as you use the -c to point to the correct configuration file you should be good. For mine I kept my dovecot config file in the default location and put the director one elsewhere and created an alias, so that I can start the director by just typing director. This might make things easier for you to manage, then you can just stop it by running "doveadm -i <instance_name> stop" alias director="sudo -E PATH=${PATH} LD_LIBRARY_PATH=${LD_LIBRARY_PATH} /home/user/dovecot/sbin/dovecot -c /home/user/dovecot/etc/dovecot/director.conf" On 09/23/2014 05:00 PM, jjhoffart wrote: >> Thanks for the replies, >> I am still fairly new to dovecot and still learning. This is a quick run down of my setup: 3 servers running iRedMail (this is a package that installs dovecot 2.1.7, postfix, and LDAP). All three servers share an NFS backend. The same 3 servers are also sitting behind a load balancer. What I want to do is use these three servers as directors and mail servers. So from the replies I have gotten I understand that I need to create 2 config files 1 for director and 1 for dovecot. Now my next question is do these config files need to be stored in /etc/dovecot or /var/run/dovecot?

I currently have two servers I am trying to cluster together. These servers will also have a shared NFS backend. I have read on the site that I will need to configure director since I am using NFS. I have read through all of the documentation on director but still need a little guidance to get things up and running. One of the questions I have is about the base_dir on the Multiple Invocations section of the wiki. It states that I will need to change the bas_dir to the new run directory, not sure what needs to happen here, can anyone help me out?

Is dovecot vulnerable to the shellshock/CVE-2014-6271 exploit?
by Joseph Tam 26 Sep '14

26 Sep '14

I'm right now handling this beach-ball sized grenade, and trying to figure out which of our services need to be locked down right away. Since dovecot passes values via environment variables based on user input (e.g. username, password, mailbox?) to auxilliary executables (including possibly bash shell scripts), is dovecot vulnerable to this exploit? (This is not a fault of dovecot, but rather bash's inadequate handling of environment variables.) For example, injection of this sort 1 LOGIN (){x;}exploit-code whatever I guess auth_username_chars would mitigate this particular attempt (assuming it can work), but other values such as mailbox names could also be injected post authentication. Can someone with working knowlegde of dovecot's internals confirm/deny whether this is a something that needs to be addressed? Joseph Tam <jtam.home(a)gmail.com>

How to configure dovecot imap to listen on multiple ports?

26 Sep '14

I need my dovecot imap server to listen on ports 143, 993, and also 30143 and 30993. What syntax do I use in (I presume) the /etc/dovecot/conf.d/10-master.conf file to do this? Thanks! Rick

Does dovecot work OK on *BSD?
by Steve Litt 26 Sep '14

26 Sep '14

Hi all, I have a dovecot server on my Debian Wheezy desktop computer. My days with Debian are limited, and I'm investigating several 'BSD's: OpenBSD FreeBSD PCBSD NetBSD DragonflyBSD etc Is there any reason Dovecot wouldn't work on any of those? Does anyone know if those OS's have packages for Dovecot, or do I need to compile it myself? Thanks, SteveT Steve Litt * http://www.troubleshooters.com/ Troubleshooting Training * Human Performance

SSL issues when proxying

I'm getting this in the log when proxying IMAP (three "valid certificate" messages, two "Invalid certificate" messages) Why is dovecot (acting as a proxy to another dovecot instance here) not recognizing the StartCom Extended Validation Server CA? .

Confusing wording on the wiki
by Alan McGinlay 24 Sep '14

24 Sep '14

Hi, I am confused by the wording of this Wiki entry: sieve = ~/.dovecot.sieve The path to the user's main active Sieve script. When ManageSieve is used, this is a symbolic link pointing to the active script in the sieve_dir directory. Avoid placing the active Sieve script inside the sieve_dir directory. So this should be a link *to* the active script in the sieve_dir directory however the active script shouldn't actually be in that directory???? http://wiki2.dovecot.org/Pigeonhole/Sieve/Configuration Confused :S /A

LMTP proxying

How exactly is LMTP proxying supposed to work? According to the example on http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy I'm only seeing "proxy" in the password_query statements. But LMTP never sends a password.

Empty mailboxes
by Daniel Miller 24 Sep '14

24 Sep '14

This is driving me nuts. I need to rebuild a server - got a notification the main drive is failing, and it's been a year or two, so it's time. Got a new drive, fresh install of Ubuntu Tantric, started installing everything needed. Data stored on a RAID array - nicely available separate from the boot/operation drive. Did a fresh compile of Dovecot, copied over the configs from the old drive, mounted the RAID...and... Dovecot starts, authenticates users - and shows empty mailboxes. Nothing shown. Full panic - reboot on old drive. All mails present. Change back - no mail. Executing "doveadm user -u username" seems to give valid results. Mailbox location appears correct (using mdbox). I setup uid/gid the same - I thought it was a rights issue but everything looks correct. What can I do to try to find the stupid mistake I'm making? -- Daniel

quota recalc problem for big maildirs
by Dawid Stawiarski - nazwa.pl 24 Sep '14

24 Sep '14

hi, we use dovecot 2.2.13, and we've lately started using maildir quota (previously fs quota was used, right now it's "quota = maildir:User quota" changed from "quota = fs:User quota:user:inode_per_mail"). When the change was applied we didn't manually forced generating maildirsize files. So, when the first deliver happens (or the file grows larger then 5KB) it starts quota recalc. However for users with big maildirs, receiving email every couple of seconds, there are tens of delivery processes each doing its own recalc (as they open file for APPEND and there's no locking). What's even worse, after all the stats and getdents (it takes a lot of IO for 60GB account with 2M emails), deliver makes stat on 'new' dir and detects changes after which it unlinks freshly created maildirsize. So possibly this will never be finished as every process drops its own work. The same thing happened when we checked the native dovecot LMTP server (every connection has its own forked process - each running independently of the others). Is it a known unwanted "feature" of maildir quota (and we should use dict quota instead) or a bug that will be fixed? cheers, Dawid Stawiarski

Re: director
by Eduardo Ramos 23 Sep '14

The configuration use to be in /etc/dovecot, and the working dir is /var/run/dovecot. You should store your configuration file in the /etc/dovecot. The dovecot.conf file can be copied to dovecot-backend.conf and dovecot-director, for example, and you will use '-c' argument of dovecot binary to load on or another. If you do this, you will need create two separated working dir, that will be defined in base_dir on each configuration file.

This is a quick run down of my setup: 3 servers running iRedMail (this is a package that installs dovecot 2.1.7, postfix, and LDAP). All three servers share an NFS backend. The same 3 servers are also sitting behind a load balancer. What I want to do is use these three servers as directors and mail servers. So from the replies I have gotten I understand that I need to create 2 config files 1 for director and 1 for dovecot. Now my next question is do these config files need to be stored in /etc/dovecot or /var/run/dovecot?

dsync error: Error: Can't delete mailbox INBOX: INBOX can't be deleted.

sieve redirect to foreign email gets “Relay access denied”
by Henry Stack 23 Sep '14

23 Sep '14

I have a postfix mail server with sql authentication and I want to implement sieve on it. Sieve is working relative good, rules who contain 'fileinto' are executed perfectly. The problem is the redirect to other servers. I configured a rule in Sieve to redirect any email containing "redirect" in subject to a specified foreign destination. # So practically a email coming from sender(a)live.de for the local user testuser(a)server.net should be redirected to destination(a)gmail.com when the subject contains "redirect" if header :contains ["subject"] ["redirect"] {redirect "destination(a)gmail.com"; stop;} when I test it I get the following log entry /postfix/smtpd[32114]: NOQUEUE: reject: RCPT from mail.server.net[xx.xx.xx.xx]: 554 5.7.1 <destination(a)gmail.com>: Relay access denied; from=<sender(a)live.de> to=<destination(a)gmail.com> proto=ESMTP helo=<mail.server.net>/ How can I tell postfix to let dovecot/sieve relay the email?

Announce: Plugin for iOS Push Email support
by Stefan Arentz 23 Sep '14

23 Sep '14

I’ve been hacking on a personal side project to support native iOS Push Email in Dovecot. This is specifically for people who are migrating their mail away from OS X Server while keeping their existing Push Email functionality. Native Push Email has some great advantages: it speeds up email notifications (usually within seconds of being handled by dovecot-lda) and it improves battery life since the native notifications flow over a single highly optimized connection to Apple’s infrastructure. Although this is at version 0.1, it is working pretty well for me and I am looking for some additional testers that are interested. Please note that it is not possible to use this project without legally running a copy of OS X Server. You can purchase OS X Server on the Mac App Store or download it for free if you are a registered Mac or iOS developer. This feature is enabled by two projects: https://github.com/st3fan/dovecot-xaps-plugin <https://github.com/st3fan/dovecot-xaps-plugin> https://github.com/st3fan/dovecot-xaps-daemon <https://github.com/st3fan/dovecot-xaps-daemon> Both projects contain a README that describes how to get things going. I have only developed and tested on Ubuntu 12.04.5 so ideally you run the same version if you are interested in playing with this project. You will need to compile some code and not be afraid of a little admin work. I am also interested in a code review. The Dovecot plugin API is barely documented and I had to guess a lot of things by looking at other plugins. An extra pair of eyes specifically on that code would be awesome. Also from a security perspective. Please file bugs! S.

Re: [wishlist] testsuite for sieve scripts, libsievetest
by Phil Carmody 23 Sep '14

> BTW: It would be nice, if I could just 'git clone' dovecot. Hi, Thomas, I happily use Felipe Contreras' excellent git-hg bridge, as I am far happier in a GIT environment than an Hg one: https://github.com/felipec/git/wiki/git-remote-hg The workflow couldn't be much easier, in particular if you set up a few aliases for the common sequences of tasks. $ hg clone http://hg.dovecot.org/dovecot-2.2 $ git clone "hg::/home/phil/dovecot-2.2" dovecot-2.2-git $ cd dovecot-2.2-git $ git checkout -b hacking $ # work... $ cd ../dovecot-2.2 $ hg pull -u $ cd ../dovecot-2.2-git $ git checkout master $ git rebase master hacking $ # more work... (OK, my workflow includes pushing too ;-) ) Hope that helps. Cheers, Phil
