[Dovecot] v2.1.10 released
by Timo Sirainen 20 Sep '12

20 Sep '12

http://dovecot.org/releases/2.1/dovecot-2.1.10.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.10.tar.gz.sig The director bugfix is pretty important at least when running in two director setups, since it can break the directors until both of them are manually shut down. I'm not entirely sure if the same happens in >2 director setups, but I'd think so (although I do wonder why I haven't seen it happen in them). BTW. I'm hoping for v2.2.alpha1 release within a week or two and to get it stabilized rather quickly. + imap: Implemented THREAD=ORDEREDSUBJECT extension. + Added "doveadm exec" command to easily execute commands from libexec_dir, e.g. "doveadm exec imap -u user@domain" + Added "doveadm copy" command. + doveadm copy/move: Added optional user parameter to specify the source username. This allows easily copying mails between different users. + Added namespace { disabled } setting to quickly enable/disable namespaces. This is especially useful when its value is returned by userdb. + Added mailbox_alias plugin. It allows creating mailbox aliases using symlinks. + imapc storage: Added imapc_max_idle_time setting to force activity on connection. + fts-solr: Expunging multiple messages is now faster. - director: In some conditions director may have disconnected from another director (without logging about it), thinking it was sending invalid data. - imap: Various fixes to listing mailboxes. - pop3-migration plugin: Avoid disconnection from POP3 server due to idling. - login processes crashed if there were a lot of local {} or remote {} settings blocks.

> we have no problem, just i want to learn how can i do that. i think > it's clear . Well... I'm pretty sure most others don't. But anyway. As in ALL Internet protocols (IMAP being no exception), letting the client read data on the server requires it to download the data. Preventing download will prevent reading the mail. Period. So if you're fine with that and just want to learn how to do it, then just disable the account in the user database. /Peter

It uses the variant defining the largest allowed content size. I choose 1024 bit (128 Byte), since that is what most of the SHA-3 candidates use, so it's hopefully somewhat future proof.

[Dovecot] Proxy connection timeouts

We are seeing a few (0-15) proxy failures like the following out of ~3m successful proxied connections a day. Average session creation load over our peak hour is about 47/sec.

[Dovecot] Mailbox aliases
by Timo Sirainen 18 Sep '12

18 Sep '12

I've been wondering about ways to handle all the various different Sent/Sent Messages/Sent Items/etc mailboxes that different clients create and if there could be a way to make them work at least somewhat better. I'm mainly thinking about ISP-like installations where users are using tons of different clients and there's no way to get everyone configured properly. Of course the eventual solution is hopefully that all the clients will support SPECIAL-USE extension, but while waiting for that maybe mailbox aliases could help some. So one possibility would be to force autocreation of wanted specific mailbox names, and create aliases for the other commonly used mailboxes. The main difference here for the current behavior is that all of the mailboxes would contain the same mails, instead of different mails going to different mailboxes with different clients. So for example: .. mailbox Sent { auto = create special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent alias_for = Sent } .. If "Sent Messages" doesn't exist: - DELETE Sent works as usual - RENAME Sent works as usual If "Sent Messages" is created: - it's symlinked to Sent - DELETE "Sent messages" deletes the symlink, not the contents - RENAME "Sent messages" isn't allowed - DELETE/RENAME Sent fails with message: Delete/Rename for Sent not allowed before "Sent Messages" is deleted. Thoughts? The main disadvantage is that clients would still see two different mailboxes, and some would download contents from both of them. I was thinking about creating some wiki page which could list the best working configurations and also a client list, which would specify if it supports SPECIAL-USE and what the default mailbox names it uses are.

[Dovecot] Released Pigeonhole v0.3.2 for Dovecot v2.1.9
by Stephan Bosch 18 Sep '12

18 Sep '12

Hello Dovecot users, I've been busy recently with some wholly unrelated Dovecot IMAP patches, so Sieve development moved a bit into the background. This release therefore consists mostly of small bugfixes. The most important change is the fix of a bug in ManageSieve's CHECKSCRIPT command that causes a segfault. Quite a few people have encountered this problem recently, so it is about time I release this now. Changelog v0.3.2: + sieve-refilter tool: improved man page documentation by explicitly specifying the syntax used for mailbox arguments. + Sieve: spamtest and virustest extensions: improved trace debugging of score calculation. + Sieve: made error messages about exceeding the maximum number of actions more verbose. - Sieve tools: fixed problems with running as root: sievec and sieve-dump now ignore mail_uid and mail_gid settings when run as root. - Sieve: fixed bug in action accounting (for limit checking): increase action instance count only when an action is actually created. - Sieve: include extension: fixed namespace separation of :global and :personal scripts. - ManageSieve: fixed segfault bug triggered by CHECKSCRIPT command. - Fixed linking with ld.gold. - Fixed several Clang compile warnings and a few potential bugs. The release is available as follows: http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.2.tar.gz http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.2.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information.

[Dovecot] trash plugin together with sieve_before ?

We have a sieve script doing sieve_before to sort spam to spam-folders. Now I'm trying to configure the "Trash" plugin, but it doesn't seem to work.. I noticed my config file says: # Space separated list of plugins to load (none known to be useful so far). Do NOT # try to load IMAP plugins here. #mail_plugins = and that doveconf doesn't list any plugins loaded for "protocol sieve". Should we load quota and trash here ? -jf

[Dovecot] Shared Mailboxes in a multi domain environment
by Alessio Cecchi 18 Sep '12

18 Sep '12

Hi, I would like to enable mailbox sharing for my users. I'm using dovecot 2.1.9 with vpopmail authentication. For security reason shared mailboxes should be available only for users of the same domain. Dovecot's wiki suggest to enable acl like this: plugin { # assumes mailboxes are in /var/mail/%d/%n: acl_shared_dict = file:/var/mail/%d/shared-mailboxes.db } but in vpopmail, and also in many others configuration, mailboxes are, for example, in /var/mail/nas1/%d, /var/mail/nas2/%d and so on, so it's difficult to restrict shared mailboxes available only for the same domain. A trick could be set acl_shared_dict to /var/mail/%d-shared-mailboxes.db, but I don't know if it's safe on an NFS environment. So, why don't provide a way to restrict shared mailboxes also for dict in SQL? One way could be to add to "user_shares" table a column "domains" which is the same domain of the mailbox'owner and a config option, for acl, like acl_only_for_same_domain =yes/no so dovecot can add a "WHERE %n = domain" for the SELECT. Are there other possible solutions?

[Dovecot] dovecot 1.x: problem with quota
by Toni Mueller 17 Sep '12

17 Sep '12

Hi, I have now verified that there is a problem with quota (and sieve?). Summary: If the "maildirsize" file gets garbled (= every once in a while), mail is getting lost randomly. Details: I have a Debian box (6.0.5/amd64) with a Postfix server (2.7.1), which delivers email via Dovecot (1.2.15) to local disk (ext3). My email is filtered via a sieve script (wish I could have something better, eg. procmail). The account data is fetched from an SQL database, and I have a default quota set in dovecot.conf (200MB). My own mailbox has no quota (*:storage=0, mentioned in the database). A client sent an email to me, which is logged as being delivered like normal to my mailbox, but doesn't show up there. After poking around, I decided to simply delete the maildirsize file and have the client send that email again, and voila, it shows up in my mailbox. At the same time, however, other emails get delivered just fine, so the heinous thing is that you don't immediately notice that something fishy is going on - only when the client actually calls you (sort of defeats some uses of email)... The problem is worsened by the fact that you can't tell *which* emails get lost - you only end up with a random subset of "your" messages. The problem occurred now after running for a few months. FWIW, the problem with the garbled maildirsize file resulted in a different user's email getting bounced due to "mailbox full", when it wasn't. Questions: * Is this a known problem (Google was unhelpful/unwieldy)? * How can I prevent the problem, short of setting up a cron job to delete that file every week? * How can I log the delivery of messages in dovecot's log, not only the POP3/IMAP activity when people fetch their email? TIA! Kind regards, --Toni++

[Dovecot] clucene build warnings?
by Charles Marcus 17 Sep '12

17 Sep '12

Hi all/Timo, Is clucene still the best/recommended method for enabling full text search? Although I haven't enabled FTS yet, I plan on doing sometime in the future, and was going to be using clucene, but before I do, I'd like to see if I need to worry about an issue I've been seeing ever since I first installed clucene (and still get every time it is upgraded)... I run gentoo linux on an amd64 server, and have always gotten this warning whenever it is updated (and also got it when I first installed it): QA Notice: Package triggers severe warnings which indicate that it may exhibit random runtime failures. /var/tmp/portage/dev-cpp/clucene-2.3.3.4-r4/work/clucene-core-2.3.3.4/src/core/CLucene/index/DocumentsWriter.cpp:129:33: warning: passing NULL to non-pointer argument 2 of ‘void* memset(void*, int, size_t)’ Please do not file a Gentoo bug and instead report the above QA issues directly to the upstream developers of this software. Homepage:http://clucene.sourceforge.net/ Has anyone else ever seen similar warnings when building clucene? Is the gentoo ebuild output correct that this is not a gentoo bug, but is in fact a problem with upstream? If so, is it harmless? Or should I try to get upstream to fix it? That said, being that ianap, I probably wouldn't be much help to them, so, Timo, any chance you can see if this is a problem that needs to be addressed with them? Thanks, -- Best regards, Charles

Here my namespace config: namespace { list = children location = maildir:/var/vmail/%%d/%%n/Maildir:INDEX=/var/vmail/%d/%n/shared/%%u prefix = Gemeinsame-Postfaecher/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = maildir:/var/vmail/%d/%n/Maildir:INDEX=/var/vmail/indexes/%u prefix = separator = / subscriptions = yes type = private } Have I got a problem with my namespace config?

[Dovecot] RFC 6154: German umlauts in special_use folder names
by Daniel Parthey 17 Sep '12

17 Sep '12

Hi, the Drafts special folder is called "Entwürfe" in German locale. How should the special_use entry in the config file look like? Would you recommended to use the encoded folder name... mailbox "Entw&APw-rfe" { special_use = \Drafts } ...or rather the utf-8 Encoding in the dovecot config file? mailbox "Entwürfe" { special_use = \Drafts } Regards Daniel -- https://plus.google.com/103021802792276734820

Hi, Is there a way to strip a backslash if it exists at the start of username like \user(a)example.com within the Dovecot LDA? I am using Dovecot 2.1.9 with a LDAP backend, so I cannot do any sort of SQL trickery. Dominic.

Hi all I receive the following error in my mail.log. Does anybody know how to configure dovecot to get rid of this ? I have one server up and running with postfix, dovecot and a mysql backend. The error above happens on another server with postfix, dovecot and a ldap backend. Any hints ? Mit freundlichem Gruß Carsten Laun-De Lellis Dipl.-Ing.

14 Sep '12

Hello I am using dovecot with POP3S and IMAPS ports, When client connect to POP3S port (995) , i can see in dovecot log file that the protocol is TLSv1 So how come the protocol is TLSv1 and not SSL ? Does the user connect t port 995 with SSL protocol then encrypt again inside the SSL session to make The TLSv1 protocol ? Or does the client use TLSv1 Protocol immediately when connect to port 995 without Using SSL protocol ? Please Help. Robert JR
