[Dovecot] using 'socat' to relay Dovecot SASL's auth socket over TCP?
by snowcrash 17 Jun '07

17 Jun '07

hi, i've been running Exim & Dovecot together on the same box. Exim's been sharing Dovecot/SASL auth info over a local unix socket. works great. i'm now splitting Exim & Dovecot onto two different boxes. iiuc, Dovecot ONLY provides a UNIX (local) socket; *not* a TCP socket for over-the-network access. SUre, I could mount the Dovecot socket's volume over NFS ... but just don't want to go there. i've just discovered, socat - Multipurpose relay http://www.dest-unreach.org/socat/ … [View More]

Hi, First of all congratulations for you development. It´s really good. We have a customer that has a copy of all inbound and outbound mail in an account. When he tries to open the mail, the process of index all mail consume all cpu and memory. How can we avoid this kinds of things? Thank you in advance, Lucas

Hi Jon, I cannot help with the specific question, but in my opinion, your first and primary goal should be to get that server updated to 1.0.1 asap... 0.99.x is no longer supported - and *very* dated...

[Dovecot] dovecot under attack
by Jon Slater 16 Jun '07

16 Jun '07

Hi, I’ve posted this before but no one was able to help. I can’t figure out what they are trying to do, and if I should be concerned. I am running dovecot version 0.99.14 on Fedora Core 4. It appears that my dovecot server is under attack. This morning in my system e-mail I saw this: dovecot: Authentication Failures: rhost= : 23431 Time(s) adm: 33 Time(s) bin: 33 Time(s) mail: 33 Time(s) mysql: 21 … [View More]Time(s) nobody: 15 Time(s) news: 14 Time(s) operator: 8 Time(s) sshd: 2 Time(s) Unknown Entries: check pass; user unknown: 23431 Time(s) But, when I check my log files I can’t find an IP address for the attacker. So, for example, if I search my logs for “operator” I see: ./messages:Jun 15 23:30:56 lambdacenter dovecot(pam_unix)[15512]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= user=operator ./messages:Jun 15 23:31:00 lambdacenter dovecot(pam_unix)[15670]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= user=operator ./messages:Jun 15 23:31:16 lambdacenter dovecot(pam_unix)[16332]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= user=operator ./messages:Jun 15 23:31:20 lambdacenter dovecot(pam_unix)[16480]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= user=operator ./messages:Jun 15 23:31:27 lambdacenter dovecot(pam_unix)[16695]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= user=operator ./messages:Jun 15 23:31:38 lambdacenter dovecot(pam_unix)[16884]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= user=operator ./messages:Jun 15 23:31:55 lambdacenter dovecot(pam_unix)[17080]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= user=operator ./messages:Jun 15 23:32:11 lambdacenter dovecot(pam_unix)[17182]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= user=operator ./audit/audit.log:type=USER_AUTH msg=audit(1181971858.967:156312): user pid=15512 uid=0 auid=4294967295 msg='PAM authentication: user=operator exe="/usr/libexec/dovecot/dovecot-auth" (hostname=?, addr=?, terminal=? result=Authentication failure)' ./audit/audit.log:type=USER_AUTH msg=audit(1181971862.772:156382): user pid=15670 uid=0 auid=4294967295 msg='PAM authentication: user=operator exe="/usr/libexec/dovecot/dovecot-auth" (hostname=?, addr=?, terminal=? result=Authentication failure)' ./audit/audit.log:type=USER_AUTH msg=audit(1181971878.710:156707): user pid=16332 uid=0 auid=4294967295 msg='PAM authentication: user=operator exe="/usr/libexec/dovecot/dovecot-auth" (hostname=?, addr=?, terminal=? result=Authentication failure)' ./audit/audit.log:type=USER_AUTH msg=audit(1181971882.379:156775): user pid=16480 uid=0 auid=4294967295 msg='PAM authentication: user=operator exe="/usr/libexec/dovecot/dovecot-auth" (hostname=?, addr=?, terminal=? result=Authentication failure)' ./audit/audit.log:type=USER_AUTH msg=audit(1181971908.712:156879): user pid=16695 uid=0 auid=4294967295 msg='PAM authentication: user=operator exe="/usr/libexec/dovecot/dovecot-auth" (hostname=?, addr=?, terminal=? result=Authentication failure)' ./audit/audit.log:type=USER_AUTH msg=audit(1181972032.080:156904): user pid=16884 uid=0 auid=4294967295 msg='PAM authentication: user=operator exe="/usr/libexec/dovecot/dovecot-auth" (hostname=?, addr=?, terminal=? result=Authentication failure)' ./audit/audit.log:type=USER_AUTH msg=audit(1181972047.607:156917): user pid=17080 uid=0 auid=4294967295 msg='PAM authentication: user=operator exe="/usr/libexec/dovecot/dovecot-auth" (hostname=?, addr=?, terminal=? result=Authentication failure)' ./audit/audit.log:type=USER_AUTH msg=audit(1181972066.325:156928): user pid=17182 uid=0 auid=4294967295 msg='PAM authentication: user=operator exe="/usr/libexec/dovecot/dovecot-auth" (hostname=?, addr=?, terminal=? result=Authentication failure)' I’ve checked my snmplog for port activity on port 110 (for POP3) and 143 (for IMAP), but I don’t see anything unusual.

[Dovecot] Per user based protocol access and pause after failed login?

Hello. Tried search, no luck, sorry, if this is already answered, but I'm still looking a solution using pam_auth how to define in dovecot which user can access which protocol, for example, default is: protocols = pop3 pop3s imap imaps I'd like to use something like this: exclude_using_pop = user1, user2, @group exclude_using_pops = user1, user2, @group exclude_using_imap = user1, user2, @group exclude_using_imaps = user1, user2, @group The idea is security and also preventing imap … [View More]

[Dovecot] SHA256 password patch
by Jasper Slits 16 Jun '07

16 Jun '07

Hi, I made a patch against branch-1.0 for SHA256 password hashing support for Dovecot. Courier Authlib supports this hashing scheme and in order to migrate from Courier to Dovecot, I've added SHA256 support to Dovecot. The attached patch is based on BSD licensed code from Olivier Gay (http://www.ouah.org/ogay/sha2/) Changes made by me in Olivier's sha2{.h,.c} code: - Prototype for sha256_transf is added to sha2.h - sha256_get_digest() is added to sha2{.h,.c} - Code for UNROLL_LOOPS is … [View More]removed - Support for SHA224,SHA384,SHA512 was removed - Functions are renamed to match those in sha1{.h,.c} - SHA256_DIGEST_SIZE is renamed to SHA256_RESULTLEN I can add safe_memset calls if requested. Patch is attached and can also be found at http://www.malochia.nl/dovecot/sha256.patch Kind regards, Jasper diff -r -u -N --exclude=Makefile.in --exclude=.deps --exclude=Makefile src/auth/password-scheme.c auth/password-scheme.c --- src/auth/password-scheme.c 2007-02-21 13:30:38.756711250 +0100 +++ auth/password-scheme.c 2007-02-21 14:18:49.645380500 +0100 @@ -10,6 +10,7 @@ #include "mycrypt.h" #include "randgen.h" #include "sha1.h" +#include "sha2.h" #include "str.h" #include "password-scheme.h" @@ -153,6 +154,17 @@ return str_c(str); } +static const char *sha256_generate(const char *plaintext, + const char *user __attr_unused__) +{ + unsigned char digest[SHA256_RESULTLEN]; + string_t *str; + sha256_get_digest(plaintext, strlen(plaintext), digest); + str = t_str_new(MAX_BASE64_ENCODED_SIZE(sizeof(digest)+1)); + base64_encode(digest, sizeof(digest), str); + return str_c(str); +} + static const void * password_decode(const char *password, unsigned int result_len) { @@ -196,6 +208,23 @@ return memcmp(sha1_digest, data, SHA1_RESULTLEN) == 0; } +static bool sha256_verify(const char *plaintext, const char *password, + const char *user) +{ + unsigned char sha256_digest[SHA256_RESULTLEN]; + const char *data; + + sha256_get_digest(plaintext, strlen(plaintext), sha256_digest); + + data = password_decode(password, SHA256_RESULTLEN); + if (data == NULL) { + i_error("sha256_verify(%s): Invalid password encoding", user); + return 0; + } + + return memcmp(sha256_digest, data, SHA256_RESULTLEN) == 0; +} + static const char *ssha_generate(const char *plaintext, const char *user __attr_unused__) { @@ -466,6 +495,7 @@ { "MD5-CRYPT", md5_crypt_verify, md5_crypt_generate }, { "SHA", sha1_verify, sha1_generate }, { "SHA1", sha1_verify, sha1_generate }, + { "SHA256", sha256_verify, sha256_generate }, { "SMD5", smd5_verify, smd5_generate }, { "SSHA", ssha_verify, ssha_generate }, { "PLAIN", plain_verify, plain_generate }, diff -r -u -N --exclude=Makefile.in --exclude=.deps --exclude=Makefile src/lib/Makefile.am lib/Makefile.am --- src/lib/Makefile.am 2007-02-21 13:30:38.792713500 +0100 +++ lib/Makefile.am 2007-02-21 14:21:59.437241750 +0100 @@ -73,6 +73,7 @@ sendfile-util.c \ seq-range-array.c \ sha1.c \ + sha2.c \ str.c \ str-sanitize.c \ strescape.c \ @@ -146,6 +147,7 @@ sendfile-util.h \ seq-range-array.h \ sha1.h \ + sha2.h \ str.h \ str-sanitize.h \ strescape.h \ diff -r -u -N --exclude=Makefile.in --exclude=.deps --exclude=Makefile src/lib/sha2.c lib/sha2.c --- src/lib/sha2.c 1970-01-01 01:00:00.000000000 +0100 +++ lib/sha2.c 2007-02-23 14:03:46.857739818 +0100 @@ -0,0 +1,257 @@ +/* + * FIPS 180-2 SHA-224/256/384/512 implementation + * Last update: 02/02/2007 + * Issue date: 04/30/2005 + * + * Copyright (C) 2005, 2007 Olivier Gay <olivier.gay(a)a3.epfl.ch> + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.

[Dovecot] different configurations for individual user
by Joshua C.S. Chen 16 Jun '07

16 Jun '07

Hi everyone, I am planning to upgrade my current uw-imap to dovecot. I am using Linux (Redhat EL 4). The main purpose is to use maildir instead of mbox. For some reason, I don't want to upgrade all users' mail boxes all at a time, but I want to change the imap server first (to dovecot), while keeping all mbox files, then convert them to maildir user by user (one user at a time). My question is: Is it possible that dovecot can setup individual user's own configuration? so that some … [View More]

[Dovecot] shared folders
by T. Horsnell 14 Jun '07

14 Jun '07

A number of our users would greatly benefit from truly shareable mail folders. I know we can bodge this with symlinks, but mailbox corruptions seem to occur when simultaneous updates are made, but this may be a client issue I guess. So I wonder if true shareability is creeping up the agenda. By true shareability, I mean such that if two users have the same folder open and one of them makes a modification to it, the display of that folder on the other user's screen immediately reflects that … [View More]

[Dovecot] How do I test new code?
by Stewart Dean 14 Jun '07

I know how to run a second instance of the *base* code (to check different functionality/config) and documented it in http://wiki.dovecot.org/RunningDovecot What I realize I don't know how to do is to run an altogether different version or build of the code as that second instance, which would be good to have to check out upgrades before they go into production. While I could do a build in the regular fashion and put DC somewhere else or name it something else, so I could invoke this … [View More]

[Dovecot] New experimental XEXEC plugin status
by Marc Perkel 12 Jun '07

12 Jun '07

No to long ago I proposed an experimental extension to the IMAP protocol to allow IMAP to execute extername server side code and talk to email plugins to create custom client/server applications over an existing authenticated IMAP connection. I am happy to say they we have working code. It's not quite ready to download yet but we do have some life happening. I have started to document it on the Dovecot wiki here. http://wiki.dovecot.org/Plugins/xexec I'm looking to see if I can generate … [View More]some interest in this. XEXEC Plugin XEXEC is an experimental non-standard extension to the IMAP protocol that allows you to run and server side application and have it communicate with email plugins (Thunderbird) allowing custom client/server applications to communicate over an existing authenticated IMAP channel. The email client sends the XEXEC command with the name of the server side module that it wishes to run along with parameters to pass to the server. Here are some examples: XEXEC blacklist add joe(a)example.com XEXEC whitelist del joe(a)example.com XEXEC changepassword MyNewPassword XEXEC forwardmail myaccount(a)yahoo.com Uses for XEXEC The XEXEC can be used to run anything but in theory it should be used for client server applications that relate to email or groupware applications like calendars and contact lists. Its main purpose is to allow email clients to set server side settings over the existing authenticated channel without having the user have to log in separately using a different application to control user settings. Examples of possible usage includes: * Setting server side white lists and black lists * Changing the password for the email account * Allowing users to set email forwarding preferences * Allowing users to set vacation messages * Allowing users to exclude email from specific countries or language character sets * Allowing users to control server side spam filter settings * Server Side Calendar and Group Contact Applications like MS Exchange has * SMTP over IMAP for sending outgoing email without separate SMTP settings * Setting rules for server side folder delivery. * Setting text message alerts to cell phones for important email notification Wouldn't it be nice if you could change your email password i your email client and have it set the new password on the server at the same time? This would eliminate the need to change the server and client passwords separately. Or imagine sending outgoing email without having to configure SMTP. You just set up the incoming email and the outgoing email works as well. Or wouldn't you like to do some of the fancy tricks that Microsoft Exchange Servers do without having to use Exchange? It is our hope that this experimental protocol will lead to significant expansion of IMAP functionality. About this Plugin This plugin is the idea of Marc Perkel of Junk Email Filter <http://www.junkemailfilter.com> who hired Nicolas Boullis ( nicolas.boullis(a)free.fr <mailto:nicolas.boullis@free.fr>) to write the code. I (Marc Perkel marc(a)perkel.com <mailto:marc@perkel.com>) am trying to get the concept out there in some sort of working form with the idea that it will catch on. Hopefully other people who find this concept useful will build on the idea, do it right, and perhaps some variation of this concept will eventually become a standard. Status This plugin is a nonstandard experimental extension to the IMAP protocol. It is offered as a proof of concept and it is my hope that it will catch on in some form and make it into the IMAP officially. At this point there is nothing on the client side to talk to anything on the server side. So this code is presently useless until more development is done. Configuration To activate and configure this plugin you have to first add it to your dovecot.conf file. You can do so as follows: protocol imap { mail_plugins = xexec } Then to add applications you specify the module name and map it to a server side executable program. xexec = module:executable Here are some examples: plugin { xexec = blacklist:/usr/local/dovecot/blacklist.sh %u xexec2 = whitelist:/usr/local/dovecot/whitelist.sh %u xexec3 = average:/usr/local/dovecot/average xexec4 = smtp:/usr/local/dovecot/smtp } The idea is that the module name will be a reference to an executable and will hide what is happening on the server. When the command XEXEC module <parameters> is passed then the server will run the executable and pass the parameters to the executable. Interacting with XEXEC A typical session with XEXEC might look like this. * OK Dovecot ready. 001 login marc(a)perkel.com password 001 OK Logged in. 002 xexec blacklist add joe(a)example.com * OK Adding joe(a)example.com to server side blacklist for marc(a)perkel.com 002 OK command exited successfully 003 xexec changepassword MyNewPassword * OK New Password set Sucessfully for marc(a)perkel.com 003 OK command exited successfully Many of the details of how everything will work under different conditions have yet to be developed. Download and Installation Coming Soon! License This software and the concepts behind is are free. No patent or copyrights are asserted on the concept. This is a gift to the world community. Code is released under GPL2. Help Needed We could use some help with this project. We haven't even started writing any client side code. We are looking for sharp people with good ideas to help develop this concept in a way that will eventually lead to becoming part of the standard. We envision that certian commands to do ordinary universal stuff (password, smpt, whit list, black list, forwarding) will become standardized so that features to set server side settings can become part of standard email applications.

[Dovecot] Getting rid of the common newbie problems
by Timo Sirainen 12 Jun '07

12 Jun '07

I think the most common Dovecot newbie problems are: - Not looking at the (correct) logs for errors - Authentication problems - Mail location problems - Mail permission problems Below are some of my ideas how I could stop people from asking these questions with future Dovecot (v1.1+) releases. Suggestions welcome. Distribution people especially should say if they're against some change. * Logging The log file problem is the most annoying one, because a lot of the other problems can be … [View More]solved once the admin figures out that Dovecot is actually giving useful error messages. Often the admin is only looking at the log file where "info" messages go (eg mail.log) because Dovecot logs its startup message and login messages there, but not where the errors go (eg mail.err). This has happened even with people who in general are experienced sysadmins. Logging to eg. /var/log/dovecot.log by default would be helpful here, but it's probably better to log via syslog by default. Cyrus logs to "local6" by default. Perhaps for Dovecot v1.1 I should make that the default too? Looks like in my Debian system the info messages then go to both /var/log/messages and /var/log/syslog. Error messages only go to /var/log/syslog. So there still isn't by default a single log file where the errors are logged, but it might help a bit. * Authentication Authentication problems can usually be solved by telling the user to set auth_debug_passwords=yes and looking at the logs. I'm not sure if there's anything that can be helped in here. Except the logging message could be updated a bit: "Aborted login: user=<asdga>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured, 1 failed authentications" So the last "n failed authentications" could be added, where n could also be 0. Another possibility would be to make Dovecot remember if there have been any successful logins (/var/lib/dovecot/success file) and if not, give a bit more helpful error messages: - Client gets: "NO Authentication failed. Refer to server log for more information." instead of the normal "NO Authentication failed." - Log contains: "Aborted login: user=<asdga>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured, 1 failed authentications (set auth_debug_passwords=yes to debug the problem)" I'm not sure if this is a good idea. * Mail location It seems to be difficult for some people to set mail_location. I don't know if anything can be done before Dovecot v2.0 where I'll split it to multiple settings, such as: driver = maildir root_dir = ~/Maildir index_dir = /var/indexes/%u Another problem that seems to be difficult to understand is why the mail directory contains "HOME_DIRECTORY_USED_BUT_NOT_GIVEN_BY_USERDB". The whole userdb concept appears to be weird. This could anyway be fixed by giving an error message earlier and failing the login with internal error. Probably the best place to give the error message would be already in the userdb lookup in dovecot-auth, but that would require that doveoct-auth knows if the home directory is really needed, and to give a useful error message it would also need to tell where it's tried to be used (mail_location, or some namespace's location, or ..). Probably too much trouble to be worth it. So the next best thing is to give the error when it's used: "Home directory is used in mail_location, but userdb didn't return a home directory" It would be nice if it didn't say userdb, but rather the userdb's name. I guess that would be possible if dovecot-auth told master (or deliver) which userdb was used, but that would normally be just extra overhead. * Mail permissions If mail location is difficult for some, then the concept of UIDs are how they're used in Dovecot is pretty much impossible for some to understand. One of the problems is that there exists "dovecot" user. So people think that their mails should be owned by the dovecot user. Although I've mentioned in everywhere I can think of that this should not be done, it won't help because either people won't read the pages or even if they do, they somehow still fail to ignore it even though it's written in bold. So unless people (and most importantly, distributions) are against it, I think the "dovecot" user should be renamed. "dovelogin" perhaps. In future I might split dovecot-auth even more, and then I would like to create a "doveauth" user as well. Another possibility would be to drop the dovecot user completely and instead use "nobody". That would mean that other nobody processes could kill Dovecot's login processes, but that's pretty much it. Once people understand that "dovecot" isn't the right user, they hit the next problem: "How do I tell Dovecot to run as vmail user?" I can paste links to wiki pages or tell them to "make userdb return uid=vmail", but that just doesn't seem to get through. There needs to be an easier way, and I think I figured out what it is: Add new "mail_uid" and "mail_gid" settings to dovecot.conf. Deprecate user_global_uid/gid in dovecot-ldap.conf and make all the userdbs mention that the uid/gid returned by userdb can be used to override the global mail_uid/gid. Perhaps also add "mail_home" template. This change makes it unnecessary to have a userdb configured at all. - "How do I tell Dovecot to run as vmail user?" - "Set mail_uid = vmail" in dovecot.conf - "Thanks" [View Less]

[Dovecot] Dovecot LDA and address extensions
by Tom Metro 12 Jun '07

12 Jun '07

I'm converting over a virtual user installation that used Postfix and maildrop with a MySQL back-end for mailbox lookups to use Dovecot LDA. The maildrop setup used a database table like: +-------------------------+--------+-------------+--------------------+ | address | owner | domain | mailbox | +-------------------------+--------+-------------+--------------------+ | postmaster(a)example.com | tmetro | example.com | .admin.postmaster/ | | root(a)example.… [View More]com | tmetro | example.com | .admin.root.lex/ | | tmetro(a)example.com | tmetro | example.com | .INBOX/ | | tmetro+spam(a)example.com | tmetro | example.com | .spam.tmetro/ | [...] where maildrop was handed ${recipient} from postfix, and it queries the above table matching ${recipient} to the address column, getting back the expression CONCAT_WS('/','/var/mail',domain,owner) as the home directory, and CONCAT_WS('/','/var/mail',domain,owner,mailbox) as the mailbox. The UID/GID are fixed, as this is a virtual user setup. So looking up the mailbox for the user postmaster(a)example.com returns: /var/mail/example.com/tmetro/.admin.postmaster/ Currently I'm using a static user database with Dovecot. This SQL appears to replicate the maildrop setup: user_query = SELECT CONCAT_WS('/','/var/mail',domain,owner) as home, CONCAT_WS('/','maildir:/var/mail',domain,owner,mailbox) as mail, 5000 as uid, 5000 as gid FROM vmbx2 WHERE userid = '%u' And this works for mail deliveries. The problem with this is that not only is a database lookup overkill for the IMAP server, as the root mail location for IMAP users follows a simple pattern adequately represented by the static userdb, it also breaks IMAP, because the returned 'mail' overrides mail_location, (currently set to maildir:/var/mail/%d/%n/), so for user tmetro(a)example.com it returns: maildir:/var/mail/example.com/tmetro/.INBOX/ instead of: maildir:/var/mail/example.com/tmetro/ (which is the same as the home directory). Can the "userdb sql" directive be added to the "protocol lda" section? Or perhaps instead create a new "auth lda" section, and move the "userdb sql" and "socket listen" directives to that section? The second issue is how to best deal with address extensions, something that wasn't fully implemented in the maildrop setup. Ideally I'd like a setup where a lookup is first performed for user+ext@domain, and if it fails to return a mailbox, then lookup user@domain. Assuming Dovecot can handle a multi-row query result (grabbing the first record and ignoring the rest), this can probably be hacked using an appropriate WHERE expression. But the difficulty is getting the address components. Postfix will provide them, but Dovecot's deliver doesn't seem to have a way of receiving them and passing them on to the user query. The example LDA setup shown here: http://wiki.dovecot.org/LDA/Postfix suggests passing the extension as an argument to the mailbox (-m) switch. But this assumes that one wants a one-to-one direct mapping between extensions and mailbox names. I suppose I could switch from: -d ${user}@${nexthop} to: -d ${recipient} and add even more complexity to the SQL to parse out the extension. But I'd rather avoid embedding the extension separator character in the SQL, and would rather eliminate it from the database as well. Maybe Sieve is the answer. I presume the argument to -m could be inspected in a Sieve script, which could then map to the desired target mailbox. The non-IMAP users (like postmaster(a)example.com) could be reimplemented as aliases that redirect to a user+ext(a)example.com address for the user responsible for that domain. But using Sieve scripts for extension to mailbox mappings seems far less elegant than using a database. Maybe I need to wedge a wrapper program between Postfix and deliver that will accept the address components from postfix, perform the lookup, and convert the results into a -d argument pointing to the "owner" (see table above) and a -m argument pointing to the mailbox. On a side note... When I used this command in postfix's master.cf: /usr/lib/dovecot/deliver -d ${user}@${nexthop} -n -m ${extension} as recommended in the wiki, the following error gets logged: ... status=bounced (command line usage error. Command output: Fatal: Unknown argument: -d Usage: deliver [-c <config file>] [-d <destination user>] [-m <mailbox>] [-f <envelope sender>] ) which doesn't make a lot of sense. I suspect what it is trying to say is that it didn't like something about the argument to the -d switch. Maybe that should be ${domain} instead of ${nexthop}. (What's up with all the whitespace between "[-m <mailbox>]" and "[-f <envelope sender>]"? Also, might be a good idea to have deliver always write errors - even startup errors - to the specified logging facility, given that not all programs that launch it will report what it writes to STDERR. I notice most postfix commands - even the ones people interact with - log errors.) I ended up switching to -d ${recipient} to emulate the old maildrop setup for now, and that worked fine. The sample dovecot.conf has: ## dovecot-lda specific settings ## # socket listen { # master { # path = /var/run/dovecot/auth-master I uncommented the first two lines, but left the 'path' directive commented, under the assumption that the comment was showing the default. But without it uncommented, the socket doesn't get created. This is an inconsistency compared to how defaults are shown elsewhere in dovecot.conf. -Tom [View Less]

[Dovecot] vpopmail quota

Hi, I'd like the vpopmail user database to return the quota settings for users, instead of having to rely on the validity of the maildirsize files. It doesn't look like this is currently possible. Would simply adding a auth_stream_reply_add call for "quota" with a suitable value in vpopmail_lookup be sufficient to make this work?

[Dovecot] SEGV when user over filesystem quota and "Move to Trash"
by Steffen Kaiser 12 Jun '07

12 Jun '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I've configured Dovecot v1.0.0 with filesystem quota and to use hardlinks. Latter I use intentionally to save disk space and to achieve that an user can delete mails even if over quota and using the "Delete to Trash" feature. The following happens, when the directory file of .Trash/* fills up and would need to be expanded, but fails because of an over-quota condition. The crash is not so problematic, because you can wait some time (I … [View More]guess until the lock of .Trash/dovecot-uidlist.lock expires) and you can delete mails from Trash to make room. However, there are leftover files in .Trash/tmp, what may make problems. First you get a "Out of quota" error in the MUA, maybe a second or a third time, too.

I'm using the dovecot available on Ubuntu Feisty (1.0rc17) and am trying to migrate from courier-imap.

[Dovecot] Multiple IP(or Host) listen in dovecot.conf.
by Yoshihiro Kawabe 11 Jun '07

11 Jun '07

Hi. Does someone make update for `Multiple IP(or Host) listen in dovecot.conf'? I made trivial patch so. But this patch doesn't solve `Support listening in multiple sockets' in TODO. It appends only the capability as multiple listen in dovecot.conf. So, `login_processes_count' becomes ambiguous. In CASE1, login_processes_count = 2, forked imap-login processes are 8. -- samples dovecot.conf applied this patch are following. CASE 1: listen = 127.0.0.1, 192.168.0.10, imap-server1, imap-… [View More]

There is no logging info, even with --enable-debug on and all .conf file directives I can find. Doing a 'ngrep port 993' shows no SSL dialog.

[Dovecot] Can't connect to SMTP outside localhost
by Jeremy Gillick 11 Jun '07

11 Jun '07

I have Dovecot setup with Postfix and can't seem to connect to to the SMTP server (port 25) unless I'm on the server itself (telnet localhost 25). For example, I cannot use my mail client, Thunderbird, to send mail from my laptop -- it cannot even connect to the server. I checked the logs and nothing shows up for the attempted connection.

[Dovecot] auth_username_format
by Sergio Souza 11 Jun '07

I configured in the archive dovecot.conf the parameter auth_username_format = "%Ld_%Ln" because the users of my server have access yours e-mail accounts based in /etc/passswd where they are registered in format domain.com_user. This configuration work without problems via pop3 and imap (squirrelmail). My server is CentOS 5.0 and dovecot is 1.0.rc15. The problem that occurs currently is: when the users go to have access the interface of change preferences (ISPCONFIG) where the supplied data of … [View More]

[Dovecot] dovecot vs. Outlook Mobile
by J.Wendland＠scan-plus.de 10 Jun '07

Hi, I am testing dovecot with Outlook Mobile 5 (OM5), which is currently not working. OM5 connects, says "NOOP" and "CAPABILITY", does login correctly and simply loggs out after that telling the user that it could not download any messages. When I put an imapproxy[0] in front of dovecot, OM5 works perfectly well. That leads me to the thought, that something in the way dovecot sends its responses makes OM5 upset. Does anybody on this have seen this before? Thanks, Jörg [0] http://www.… [View More]
