[Dovecot] Defer emails until the user is ready to deal with them (snooze button / bring-forward file / bring-up file for emails)
by Chris Laif 19 Feb '13

19 Feb '13

Hi, I would like to add a feature to my email-client (Thunderbird) which stops emails from showing up until a specific time (e.g. having buttons for: show again this evening, tomorrow, next week, next month ...). As far as I've learned this is not possible with IMAP: - storing the 'do-not-show-until-time' within a custom header-field requires down- and uploading of the whole email and therefore causes problems especially with large emails - IMAP keywords are limited are limited in quantity and can not be compared with datetime functions Any suggestions will be greatly appreciated!

[Dovecot] Get rid of inotify in 2.1.15
by Martin Rabl 19 Feb '13

19 Feb '13

Hi, after update to Dovecot 2.1.5 (Ubuntu 12.04, dovecot from https://launchpad.net/~kokelnet/+archive/dovecot21) we are getting a huge ;-) bunch of log entries about " imap(USERNAME): Warning: Inotify instance limit for user 5000 (UID vmail)". At last I did an echo 512 > /proc/sys/fs/inotify/max_user_instances but the logentries did appear again after some minutes. Maybe you have a hint for me? Thank you! At the bottom my current configuration. -- Greetings, Martin Rabl # 2.1.15: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-36-generic x86_64 Ubuntu 12.04.2 LTS auth_anonymous_username = anonymous

[Dovecot] statistics on proxy ???
by Marco Giunta 19 Feb '13

19 Feb '13

Hi at all, could I have imap statistics on my dovecot proxy server ?? Here my config: # 2.1.13: /etc/dovecot/dovecot.conf ... mail_plugins = stats ... plugin { ... stats_refresh = 30 secs stats_track_cmds = yes } ... service stats { fifo_listener stats-mail { mode = 0666 } } ... protocol imap { ... mail_plugins = stats imap_stats } File '/var/run/dovecot/stats' is always 0 byte: # ls -la /var/run/dovecot/stats srw-------. 1 root root 0 Feb 18 14:24 /var/run/dovecot/stats and 'dovecotadm' say always: # doveadm stats dump session doveadm(root): Info: no statistics available Is there something wrong in my config, or stats are not available on proxy ??? Cheers, Marco

[Dovecot] Private message flags in shared mailboxes
by Timo Sirainen 19 Feb '13

19 Feb '13

I'm wondering a bit how these should work. Comments welcome. In v2.2 the recommended way to enable private flags for shared mailboxes is to create private indexes with :INDEXPVT=<path>. This creates dovecot.index.pvt[.log] files which only contain message UIDs and flags. The indexes are updated somewhat lazily by updating them whenever user has the shared mailbox opened and it gets synced. 1. What would be a good place to configure which flags are shared and which are private? Currently it forces \Seen flag to be private and others not. With Maildir I used to have the idea of configuring these in dovecot-shared file, but that's a rather annoying extra file. Then again it could be cached into dovecot.index. Another possibility would be in dovecot-acl file, but public mailboxes might be enabled without ACL plugin. Mailbox attributes (for URLAUTH and for future METADATA) also exist in v2.2, but they require configuring a dict for them, which isn't very efficient either to read every time a mailbox is accessed. Mailbox's admin user should be able to do this somehow via IMAP protocol also. METADATA would pretty much be required for that I guess. 2. Private flags aren't currently inherited from the primary (shared) flags. With user-shared mailboxes this is good, because the owner doesn't have private indexes for the mailboxes, so when owner reads a mail it gets a \Seen flag in the primary index. If that mailbox was shared to someone else, the \Seen flag shouldn't be set. But this also means that for truly shared (public) mailboxes that have no owner you can't set initial flags with Sieve's addflag command (e.g. \Seen flag to high-scored mails in Spam). I guess it could be possible to change this so that the inheritance is done for public namespaces but not for shared namespaces, but is that really a good idea either?.. 3. Currently COPY/APPEND ignore any private flags (which also means dsync won't set them always). Fixing this would require remembering these flags, committing the save to primary index, syncing the private index to get the new mails added there, then updating their flags (or doing it directly at sync stage with some kludging code). To avoid race conditions the private index would need to be locked before committing the save. I guess this is doable.. 4. Private keywords aren't supported. I guess not much worse than system flags, but more code complexity. Wonder if anyone would care about them.

Hi all, I had a imaps dovecot server working normal. I wanted to isolate the Internet connection by placing a proxy imap(Intranet connections still connect directly to the imap server). Yesterday I set up oneproxy imaps dovecot and thereafter, imap dovecot logs on errors: imap-login: Error: OpenSSL malloc() failed. You may need to increase login_process_size Need dovecot more memory with imap proxy connections than direct connections?

What wrong with this build? Maybe there is another way to do it? For example create backup in local temporary directory and synchronize this one and working storage.

[Dovecot] accumulating orphaned processes

I'm getting orphaned processes on our mail servers. Some machines has processes hanging around from a week ago.

[Dovecot] Requested xxxx scheme, but we have a NULL password after upgrade
by PhilQ 15 Feb '13

15 Feb '13

I'm having an issue I can't seem to work around after upgrading from Dovecot 1.0.7 to 1.2.17. After getting Dovecot 1.07 working on CentOS 5.9, I decided that it might be wise to upgrade to a later version, so I stuck with 1.x and went with 1.2.17, which I had to compile from source. CentOS was originally using /etc as the starting path for Dovecot files but the source distribution puts most of the stuff under /usr/local/etc. After the usual config>make>make install dance I made the necessary changes to point to the new libraries, modules, etc. and the "imap-login: Fatal: Dovecot version mismatch: Master is v1.2.17, login is v1.0.7...." messages went away. After doing this though I cannot login, I get the following error messages: Feb 13 15:50:40 auth(default): Info: client in: AUTH 7 NTLM service=imap lip=192.168.2.102 rip=192.168.2.100 lport=143 rport=1470 Feb 13 15:50:40 auth(default): Info: client out: CONT 7 Feb 13 15:50:40 auth(default): Info: client in: CONT 7 TlRMTVNTUAABAAAAB4IIogAAAAAAAAAAAAAAAAAAAAAFASgKAAAADw== Feb 13 15:50:40 auth(default): Info: client out: CONT 7 TlRMTVNTUAACAAAAMAAwADAAAAAFAooATj7XW6ve2hwAAAAAAAAAADgAOABgAAAAUwBlAHIAdgBlAHIAMQAuAGgAZQByAHMAYwBoAGwAYQB1AHIAZQBuAC4AYwBvAG0AAwAwAFMAZQByAHYAZQByADEALgBoAGUAcgBzAGMAaABsAGEAdQByAGUAbgAuAGMAbwBtAAAAAAA= Feb 13 15:50:40 auth(default): Info: client in: CONT 7 TlRMTVNTUAADAAAAGAAYAGoAAABoAGgAggAAAAAAAABIAAAAEAAQAEgAAAASABIAWAAAAAAAAADqAAAABQKIAgUBKAoAAAAP*CENSORED*bgBiAFEAUwBFAC0AVwBJAE4AWABQAEXO6p/WuopqQ02x1kzJGW3NoQELKw32N88JqkbMOYOVErhiS492elwBAQAAAAAAA*CENSORED*ysN9jcAAAAAAwAwAFMAZQByAHYAZQByADEALgBoAGUAcgBzAGMAaABsAGEAdQByAGUAbgAuAGMAbwBtAAAAAAAAAAAA Feb 13 15:50:40 auth(default): Info: cache(pquesinb,192.168.2.100): miss Feb 13 15:50:40 auth(default): Info: passwd-file(pquesinb,192.168.2.100): lookup: user=pquesinb file=/etc/dovecot.users Feb 13 15:50:40 auth(default): Info: password(pquesinb,192.168.2.100): Requested NTLM scheme, but we have a NULL password Feb 13 15:50:40 auth(default): Info: cache(pquesinb,192.168.2.100): miss Feb 13 15:50:40 auth(default): Info: password(pquesinb,192.168.2.100): passdb doesn't support credential lookups Feb 13 15:50:40 auth(default): Info: cache(pquesinb,192.168.2.100): miss Feb 13 15:50:40 auth(default): Info: password(pquesinb,192.168.2.100): passdb doesn't support credential lookups Feb 13 15:50:40 auth(default): Info: cache(pquesinb,192.168.2.100): miss Feb 13 15:50:40 auth(default): Info: password(pquesinb,192.168.2.100): passdb doesn't support credential lookups Feb 13 15:50:40 auth(default): Info: cache(pquesinb,192.168.2.100): miss Feb 13 15:50:40 auth(default): Info: password(pquesinb,192.168.2.100): passdb doesn't support credential lookups Feb 13 15:50:42 auth(default): Info: client out: FAIL 7 user=pquesinb Looking at the log from the old version while it was working, I was getting messages like the following: dovecot: Feb 04 14:14:21 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 04 14:14:21 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 04 14:15:03 Info: IMAP(pquesinb): Disconnected: Logged out dovecot: Feb 04 14:15:03 Info: IMAP(pquesinb): Disconnected: Logged out dovecot: Feb 04 14:15:23 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 04 14:15:23 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 04 14:16:05 Info: IMAP(pquesinb): Disconnected: Logged out dovecot: Feb 04 14:16:05 Info: IMAP(pquesinb): Disconnected: Logged out /etc/dovecot.users contains a list of usernames. Is this error the result of additional security which has been incorporated into the later version of Dovecot, or is it because my installation of the later version from source is broken, somehow incompatible, etc? Dovecot was configured to use PAM and it appeared to know the password of my account, failing when it was entered incorrectly so I'm assuming that it was successfully using PAM. I kept the same syntax in the later config file. >From dovecot.conf: passdb pam { # [session=yes] [setcred=yes] [failure_show_msg=yes] [max_requests=<n>] # [cache_key=<key>] [<service name>] # # session=yes makes Dovecot open and immediately close PAM session. Some # PAM plugins need this to work, such as pam_mkhomedir. # # setcred=yes makes Dovecot establish PAM credentials if some PAM plugins # need that. They aren't ever deleted though, so this isn't enabled by # default. # # max_requests specifies how many PAM lookups to do in one process before # recreating the process. The default is 100, because many PAM plugins # leak memory. # # cache_key can be used to enable authentication caching for PAM # (auth_cache_size also needs to be set). It isn't enabled by default # because PAM modules can do all kinds of checks besides checking password, # such as checking IP address. Dovecot can't know about these checks # without some help. cache_key is simply a list of variables (see # doc/wiki/Variables.txt) which must match for the cached data to be used. # Here are some examples: # %u - Username must match. Probably sufficient for most uses. # %u%r - Username and remote IP address must match. # %u%s - Username and service (ie. IMAP, POP3) must match. # # The service name can contain variables, for example %Ls expands to # pop3 or imap. # # Some examples: # args = session=yes %Ls args = cache_key=%u dovecot #args = dovecot } If anyone could give me some ideas on where to go from here, I'd really appreciate it. If there's little chance of getting the newer version to work with CentOS 5 then I'm ready to just drop back to the older version.

Re: [Dovecot] Authentication with many Windows AD
by Antonio Alberola 14 Feb '13

14 Feb '13

Hi, > You can set as many databases as you want. Check this: > > http://wiki2.dovecot.org/PasswordDatabase > http://wiki2.dovecot.org/Authentication/MultipleDatabases This solution is valid if I have only one domain. In case you have more than one domain, you need authenticate in the appropriate LDAP server. Is That correct? I'm going to explain my particular case. I have five Windows domains with some users who belong to those domains. I also have other users who are authenticated with local UNIX accounts. The only thing that I can do (I think) is using a Radius server. But, I'd rather not use it.

[Dovecot] Authentication with many Windows AD
by Antonio Alberola 14 Feb '13

14 Feb '13

Dear All, I'm a new user of Dovecot and I need support with the authentication process. I use Dovecot 2.0.9 and Postfix 2.6.6 on host x86_64-redhat-linux-gnu 2.6.32-279.14.1.el6.x86_64 CentOS release 6.3 (Final) I need to select the validation method depending on the user. I have users that have to be authenticate with UNIX account, and I have others thats have to be authenticate with Windows AD. For example, some sysadmins and special accounts needs validate with Unix accounts. Other normal users have to authenticate with Windows AD, I have many Windows controllers. Some users authenticate to a specific Windows AD and other users are validated in another one. How I can do this? Thank you very much. Antonio Alberola

[Dovecot] FreeBSD, Dovecot and ZFS
by Jason Lock 13 Feb '13

13 Feb '13

Mail Issues - FreeBSD Hello, my apologies if this may be the wrong forum but hoping that maybe someone might be able to provide some insight. Have a very sporadic and strange issue with our mail servers running Dovecot on FreeBSD. There are three servers hosting Dovecot with FreeBSD as the underlying operating system. All three connect to a NAS server, again running FreeBSD and ZFS. When the specific issue occurs, clients connecting to check mail via POP3 or IMAP experience long delays and timeouts. To the point where POP3 Logins fail due to the timeouts. The issue is further compounded by clients increasing the number of attempts to check mail. Part of the frustration in attempting to diagnose the issue is not knowing the root cause or symptom that initates the issue. Wondering if anyone has experienced anything similar, or suggestions on ways to help identify the root cause

by Piotr Rotter 13 Feb '13

Hello, I have issue with dovecot (v. 2.1.13)configuration after implementation dovecot-lda (I used maildrop earlier). Now i have 9 servers with storage by NFS v3. My problem is frequently dovecot-uidlist crashing. 2013-02-13T13:34:02.447969+01:00 k1 dovecot: imap(user(a)domain.com): Error: Broken file /path_to_mailbox/dovecot-uidlist line 3170: Invalid data: 2013-02-13T13:34:34.527715+01:00 k1 dovecot: pop3(user(a)domain.com): Error: Broken file /path_to_mailbox/dovecot-uidlist line 367: Invalid data: It happens few time in minute for diferent users and has effect to re retriving messages by pop3 clients.

[Dovecot] backing up maildir dovecot files
by David Mehler 13 Feb '13

13 Feb '13

Hello, I'm having to migrate servers. Both are dovecot2 systems. I'm wanting to copy over my mail store from one system to the other. I'd like to preserve dates/times of emails. These are maildir setups on both boxes, I'd like to be as transparent to the end user as possible. I currently have the first dovecot system offline and the second dovecot system is offline. Recommendations? Thanks. Dave.

[Dovecot] dsync 2.1.10 does not correctly handle renames of mailbox subtrees
by Karol Jurak 13 Feb '13

13 Feb '13

Hi, It seems that dsync 2.1.10 does not correctly handle renames of mailbox subtrees. The scenario is as follows. There are two servers, A and B, both running dovecot 2.1.10 and configured to use mdbox. Automatic replication between them is disabled, ie. replication plugin is not active and replicator service has process_min_avail = 0. I perform the following actions: 1. On A: doveadm mailbox create -u test_user a a/b a/b/c d 2. On A: doveadm sync -u test_user -d The result is as expected: on both A and B there are a/b/c and d mailboxes. Now I connect to A via IMAP and rename a/b to d/b. The result is as expected: on A there are a and d/b/c mailboxes. Next I execute on A 'doveadm sync -u mailstoragetest -d' and now the result is not as expected: there are a/b/c and d/b subtrees on both A and B and a/b is just a directory, ie. it does not contain dbox-Mails (the rest are proper mailboxes). dovecot.mailbox.logs have the following records appended to them: A: #2112: rename 33259783092361d18c60ba1c7cfe973c (2013-02-12 10:42:55) - this probably is the rename of a/b to d/b (recursive, ie. including children - in this case a/b/c => d/b/c) by the IMAP client #2136: rename ee2be6da91ae879476b152d7ca041f1b (1970-01-01 01:00:00) - rename of d/b/c to a/b/c by dsync (unexpected/incorrect) B: #1104: rename 33259783092361d18c60ba1c7cfe973c (1970-01-01 01:00:00) - rename of a/b to d/b (non recursive) by dsync What seems to be missing is the record in A's dovecot.mailbox.log describing the rename of a/b/c to d/b/c (or in general case the set of records describing the renames of all the children of a/b). Would appending such records allow dsync to make correct decisions as to which mailboxes and on which servers to rename?

What namespace config do you have? I got more info from the user that had this problem. He reported that he was was setting up a new Email client (Nexus4 Android) and he sent me a screenshot of his setup. Everything look ordinary except perhaps the IMAP prefix set to "mail". My setup documents inform users to leave it blank, but sometimes they use "mail/", a holdover from the uw-imapd days. I provide some aliases for that, but I don't know what would happen if you leave off the trailing "/". My namespace settings as reported by dovecot -n: namespace { inbox = yes location = prefix = separator = / } (The following are aliases to keep backward compatibility) namespace { alias_for = hidden = yes list = no location = prefix = / separator = / } namespace { alias_for = hidden = yes list = no location = prefix = mail/ separator = / } namespace { alias_for = hidden = yes list = no location = prefix = ~/mail/ separator = / } namespace { alias_for = hidden = yes list = no location = prefix = ~%u/mail/ separator = / } I've asked the user to change his prefix, and he'll probably report back.

[Dovecot] Is there any way to mask or hide the INBOX label for Dovecot 1.2.x Shared Mailboxes?
by Jason Discount 13 Feb '13

13 Feb '13

Hello, I'm setting up a new Dovecot sever to replace an old Cyrus server, and need to keep things as consistent as possible. I have a couple local accounts, like junkmail and notjunkmail that users get shared access to, and can drop things in to train sa-update. However, when users share over junkmail's inbox, it's displayed in the hierarchy: • Other Users • junkmail • INBOX Is there any way to get junkmail's INBOX to just show up at Other Users/junkmail and not require that extra depth? • Other Users • junkmail I'm running Debian Squeeze and the standard dovecot package available therein: > # uname -a > Linux internet.digitalquay.com.au 2.6.32-5-xen-amd64 #1 SMP Sun Sep 23 13:49:30 UTC 2012 x86_64 GNU/Linux > #dovecot --version > 1.2.15 I'm running in a configuration where all mail is owned by the vmail user, due to the impression I'm under, that it's a better way if there is to be shared mailboxes.

[Dovecot] Marking messages read / retaining date with Sieve
by Bret Martin 13 Feb '13

13 Feb '13

I'm trying to mark several hundred thousand messages as read as they are delivered via dovecot-lda(1). (I'm importing some mail from another format for migration purposes.) I've been able to do this with Sieve, but it has the side effect that the messages' received and saved dates are set to the current date, and Apple Mail (at least) uses one of these to display the message date. Without the Sieve filter in place, the dates are retained based on the From_ line as I would like. Does anyone know of any way I can either - retain the date when delivering using Sieve? - systematically mark a specific set of messages as read *after* delivery instead, perhaps with doveadm(1)? (even marking *everything* read would work in this particular case. I couldn't find any way to set flags with doveadm) Thanks, --Bret

[Dovecot] POLL: v2.2 to allow one mail over quota?
by Timo Sirainen 12 Feb '13

12 Feb '13

Currently if user is 1MB under quota and someone tries to deliver mail that is over 1MB, Dovecot rejects the mail. But smaller mails aren't rejected probably for days. So user might not even realize that they didn't receive one of the mails. Also having a user "almost over quota" is a rather strange state I think. So what do you think about v2.2 allowing delivery of one last mail even if it brings the user over quota? Except add a limit that if the message size is as much as the user's entire quota limit it wouldn't be added (or 50% or ..?). Also IMAP wouldn't allow this, since user would get an error anyway. I could make this also optional, but if nobody really wants to keep the old behavior there's really no point in adding the option.
