[Dovecot] SHA512-CRYPT scheme fails password verification
by Jouko Nikula 25 Dec '13

25 Dec '13

Hello, If I try to use the crypt schemes provided by libc. I fail as follows: jnikula@jlaptop:~/$ doveadm pw -s SHA512-CRYPT -p 123456 {SHA512-CRYPT}$6$to2umWLDtqvzS8SV$ZGpBeGNKuUN/2HKG6I2BEAt.Gzrz/y.SZDkos2GT2ik8obnp3XCFWfVsKVriJa6jjHULmLIqCSSyaF5YrTH7u. jnikula@jlaptop:~/$ doveadm pw -t {SHA512-CRYPT}$6$to2umWLDtqvzS8SV$ZGpBeGNKuUN/2HKG6I2BEAt.Gzrz/y.SZDkos2GT2ik8obnp3XCFWfVsKVriJa6jjHULmLIqCSSyaF5YrTH7u. -p 123456 doveadm(jnikula): Fatal: reverse password verification check failed: Password mismatch Using SHA512 sum scheme (-s SHA512) works ok in the same manner. I have dovecot version 2.2.9 on Linux 3.11.0-14-generic x86_64 Ubuntu 13.10 and I get the same results on 32-bit Debian as well. Does anyone have idea what's wrong? Thanks in advance, Jouko Nikula

[Dovecot] Patch for Dovecot's quota policy daemon
by Peer Heinlein 24 Dec '13

24 Dec '13

Hi Timo, we wrote a simple Patch for the Dovecot quota policy daemon. If a user is over quota, I prefer blocking the user sending e-mails, so I need a policy daemon, that's able to use the envelope or sasl sender as lookup key. I'd be happy if that patch can become part of the normale Dovecot releases. Peer -------- Original-Nachricht -------- Betreff: Re: Fwd: Quota-Patch Datum: Wed, 11 Dec 2013 17:33:45 +0100 Von: Stephan Seitz <s.seitz(a)heinlein-support.de> Organisation: Heinlein Support GmbH An: Peer Heinlein <p.heinlein(a)heinlein-support.de> Parameter r Code ENUM QUOTA_MATCH_RECIPIENT Stringmatch recipient= ${recipient} This macro expands to the complete recipient address.

Parameter S Code ENUM QUOTA_MATCH_SASLSENDER Stringmatch sasl_sender= ${sasl_sender} This macro expands to the SASL sender name (i.e. the original submitter as per RFC 4954) in the MAIL FROM command when the Postfix SMTP server received the message.

[Dovecot] Eliminate legacy INBOX namespace - how?
by Charles Marcus 24 Dec '13

24 Dec '13

Hi all, Our mailstore was converted from a Courier-IMAP system last year, but I am planning a migration to a shiny new VM, and would really like to clean things up and do away with the legacy INBOX namespace. My goal is to simplify IMAP client setup - no special 'INBOX' namespace needed, they just enter the server info and credentials. Also important because I will be rolling out SOGo, which has a nice web interface, and I want the mailstore to be as close to default dovecot settings as possible - although I do plan on converting from maildir to mdbox when I do the conversion I also don't want other folders to show up as subfolders of the Inbox in IMAP clients, they should all show up on the same level as the Inbox. I've read http://wiki2.dovecot.org/Migration/Courier, but I don't see anything about how to eliminate this stupid legacy INBOX. namespace, so that new IMAP clients won't show all folders as subfolders of the INBOX unless/until they add the INBOX namespace prefix in the advanced settings. I've also been reading http://wiki2.dovecot.org/Namespaces, but I'm still confused as to how to go about this. Currently I have: namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = INBOX. separator = . } The wiki recommends avoiding the 'alternative' of having two different namespaces, so I don't want to do that. Also - it would be ok if existing clients had temporary issues displaying folders properly until the INBOX prefix was removed (I would give everyone plenty of advance warning). Anyone ever done this before? Any suggestions Timo? Note: I am planning a migration to a new mail server (VM), so could make any filesystem layout changes when I do this if necessary. Thanks, -- Best regards, */Charles/*

[Dovecot] Is the users password available from a mail_filter?
by martijn.list 23 Dec '13

23 Dec '13

Hi, I'm working on a Dovecot encryption module which uses the mail filter plugin to encrypt/decrypt the message "on the fly". I was wondering whether it is possible to access the password (or a hashed password) of the user. It seems that only the user (using the %u parameter) is available to the mail_filter plugin. Any idea how to get hold of the (possibly hashed) password? Kind regards, Martijn Brinkers

[Dovecot] [dovecot-2.2.5] Duplicates in mdbox
by radek 23 Dec '13

23 Dec '13

Hi I have strange situation with one of mailboxes in mdbox format. Some messages are duplicated, not all. I am sure that is not sieve or another mail client issue, because access is via roundcube without sieve plugin. In maillog I have not found any suspicious information about this problem and i can see that from postfix do dovecot-lda was piped only one copy of message. Radek

[Dovecot] Horde + dovecot metadata support
by Andreas Schulze 23 Dec '13

23 Dec '13

Hello, Horde (http://horde.org) has the ability to store its preferences direct into a users imap mailbox using imap metadata extension. There are two implementations of the imap extension. 1. a dovecot plugin: http://hg.dovecot.org/dovecot-metadata-plugin 2. dovecot itself: http://www.dovecot.org/list/dovecot/2013-November/093243.html I setup Horde and dovecot-2.2.5 to use this extension and it works well using 1.) Now, with dovecot-2.2.9, the plugin fail to compile (unrelated problem on my side). So I tried 2.) But here I get a Horde-Error "Error in IMAP command GETMETADATA: Invalid arguments." I enables mail_debug but saw no helpfull logging. mail_attribute_dict = file:/tmp/%Lu/dovecot-attributes remote horde.testserver.ip/32 { imap_metadata = yes mail_debug = yes } Also I created directory /tmp/$my_login_id (mode 777) but dovecot also created no files. neither it logs anything about it. This is a sample imap session generated by horde: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN AUTH=LOGIN] Dovecot ready. 1 AUTHENTICATE PLAIN *** 1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE BINARY MOVE METADATA QUOTA] Logged in 2 NAMESPACE * NAMESPACE (("" "."))

Are there any hints or is the metadata extension just not fully implemented in dovecot?

[Dovecot] auth: Error: net_accept() failed: Too many open files
by boyd yang 23 Dec '13

23 Dec '13

Hi All, I got below errors when I do some 2000 users concurrency test against dovecot 2.1.7. Dec 23 10:18:52 auth: Error: net_accept() failed: Too many open files Dec 23 10:18:52 auth: Error: net_accept() failed: Too many open files Dec 23 10:18:52 auth: Error: net_accept() failed: Too many open files Dec 23 10:18:52 auth: Error: net_accept() failed: Too many open files Dec 23 10:18:52 auth: Error: net_accept() failed: Too many open files Dec 23 10:18:52 auth: Error: net_accept() failed: Too many open files Dec 23 10:18:52 auth: Error: net_accept() failed: Too many open files Dec 23 10:18:52 auth: Error: net_accept() failed: Too many open files Dec 23 10:18:52 auth: Error: net_accept() failed: Too many open files Dec 23 10:18:52 auth: Error: net_accept() failed: Too many open files Dec 23 10:18:52 auth: Error: net_accept() failed: Too many open files I seems the auth process become the bottleneck as there is only one auth process. service auth-worker { process_limit = 1000 } service imap-login { process_min_avail = 48 service_count = 0 } service imap { process_limit = 10240 process_min_avail = 8 } I find that the auth process does not open too many files with lsof, and my limit is very big(1000000). How to fix this? Thanks!
