[Dovecot] Dovecot SASL: SCRAM-SHA-1 Authentication Fails
by Thomas Reim 26 Feb '13

26 Feb '13

Dear all, I use Dovecot SASL (2.1.15) on Ubuntu 12.04 for IMAP authentication and Postfix SASL authentication. I tried to setup SCRAM-SHA-1 as SASL mechanism. This works well on Dovecot's client side towards my OpenLDAP server (with libsasl-2), but fails on the server side (IMAP and SMTP). In the following, there's an extract from Dovecot's log, when using mutt as SMTP client: dovecot: auth: Debug: auth client connected (pid=0) dovecot: auth: Debug: client in: AUTH#0111#011 SCRAM-SHA-1#011 service=smtp#011 nologin#011 lip=192.168.0.65#011 rip=192.168.0.65#011 secured#011 resp=<hidden> dovecot: auth: scram-sha-1(?,192.168.0.65): authzid not supported dovecot: auth: Debug: client passdb out: FAIL#0111 postfix/smtpd[7621]: warning: markaurel.gas.de[192.168.0.65]: SASL SCRAM-SHA-1 authentication failed Here's the log, when using mutt as IMAP client: dovecot: auth: Debug: auth client connected (pid=23409) dovecot: auth: Debug: client in: AUTH#0111#011 SCRAM-SHA-1#011 service=imap#011 secured#011 session=<session ID>#011 lip=192.168.0.65#011 rip=192.168.0.65#011 lport=143#011 rport=36543#011 resp=<hidden> auth: scram-sha-1(?,192.168.0.65,<session ID>): authzid not supported auth: Debug: client passdb out: FAIL#0111 In the following is mutt's output: imap_authenticate: Trying method scram-sha-1 SASL local ip: 192.168.0.65;36543, remote ip:192.168.0.65;143 External SSF: 128 External authentication name: myname mutt_sasl_cb_authname: getting authname for mail.mydomain.local:143 mutt_sasl_cb_authname: getting user for mail.gas.de:143 mutt_sasl_cb_pass: getting password for myname@mail.mydomain.local:143 Authentifiziere (SCRAM-SHA-1)... 4> a0002 AUTHENTICATE SCRAM-SHA-1 <uuencoded string> 4< a0002 NO [AUTHENTICATIONFAILED] Authentication failed. IMAP queue drained imap_auth_sasl: scram-sha-1 failed I've configured mutt, so that it immediately retries the SASL authentication using DIGEST-MD5. This 2nd try is succesful and mutt gets access to the imap/smtp service. Any hints, what's going wrong here?

[Dovecot] Dovecot auth works when tested with doveadm, but fails with Postfix
by Darren Pilgrim 26 Feb '13

26 Feb '13

I have three postfix 2.9.5 servers: chombo, rush, yoshi. Chombo relays to rush and yoshi for outbound email. Outbound relay requires SASL authentication. Rush and yoshi run Dovecot 2.1.12 servers with simple passwd-file backends. If I create a new password hash for chombo's user, houseloki, on either rush or yoshi: # doveadm pw -u houseloki -p <password> {CRAM-MD5}... Then I add that to rush and yoshi's passwd file: houseloki@_auth.bluerosetech.com:{CRAM-MD5}... Then `doveadm reload`, it works fine: # doveadm auth houseloki <password> passdb: houseloki auth succeeded extra fields: user=houseloki(a)_auth.bluerosetech.com So I add that username and password to the smtp_sasl_password_maps hash file on chombo, reload postfix, and then try to relay something from chombo, it fails with rush and yoshi logging warnings like: Feb 19 03:32:33 yoshi postfix/smtpd[75783]: warning: chombo.example.com[2001:db8::2]: SASL DIGEST-MD5 authentication failed: <really long string redacted> Rush and yoshi have other hashes in their passwd files, and if I configure chombo to use one of those, it works fine. Those hashes use digest-md5 and are at least a few years old. I tried that scheme instead of the default cram-md5, as well as several others, but none work. I've poured over the wiki and man pages, but can't find the problem. What am I missing? Why can I not generate new hashes correctly?

25 Feb '13

Hello, I have some problems with (listing) subscriptions on my test system running 2.2beta2 (compared with 2.1.15, configuration and Maildir content unchanged): With 2.1.15: 0 lsub "" "*" * LSUB () "." "INBOX.Trash" * LSUB () "." "INBOX.in2009" * LSUB () "." "INBOX.test" * LSUB () "." "INBOX.test.test2" * LSUB () "." "INBOX.in2010" * LSUB () "." "INBOX.in" * LSUB () "."

[Dovecot] v2.2.rc1 released
by Timo Sirainen 25 Feb '13

25 Feb '13

http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc1.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc1.tar.gz.sig A few fixes since beta2. Also added tcp and tcps (=tcp+ssl) targets for dsync, where the destination needs to be a doveadm-server listener. I'm planning on releasing v2.2.0 in 1-2 weeks if no major problems are found. Please test and report any bugs found. BTW. I've also gone through basically all of my unread emails. If you haven't gotten a reply to something, ask again. Here's again all the biggest changes since v2.1: * When creating home directories, the permissions are copied from the parent directory if it has setgid-bit set. For full details, see http://wiki2.dovecot.org/SharedMailboxes/Permissions * "doveadm auth" command was renamed to "doveadm auth test" * IMAP: ID command now advertises server name as Dovecot by default. It was already trivial to guess this from command replies. * dovecot.index.cache files can be safely accessed only by v2.1.11+. Older versions may think they're corrupted and delete them. * LDA/LMTP: If saving a mail brings user from under quota to over quota, allow it based on quota_grace setting (default: 10% above quota limit). * pop3_lock_session=yes now uses a POP3-only dovecot-pop3-session.lock file instead of actually locking the mailbox (and causing IMAP/LDA/LMTP to wait for the POP3 session to close). * mail_shared_explicit_inbox setting's default switched to "no". * ssl_client_ca_dir setting replaced imapc_ssl_ca_dir and pop3c_ssl_ca_dir settings. + Implemented IMAP MOVE and BINARY extensions + Implemented IMAP CATENATE, URLAUTH and URLAUTH=BINARY extensions (by Stephan Bosch). + Implemented IMAP NOTIFY extension. Requires mailbox_list_index=yes to be enabled. + Redesigned and rewritten dsync. The new design makes the syncing faster, more reliable and more featureful. The new dsync protocol isn't backwards compatible with old dsync versions (but is designed to be forwards compatible with future versions). + All mailbox formats now support per-user message flags for shared mailboxes by using a private index. It can be enabled by adding :INDEXPVT=<path> to mail location. This should be used instead of :INDEX also for Maildir/mbox to improve performance. + Improved mailbox list indexes. They should be usable now, although still disabled by default. + Added LAYOUT=index. The mailbox directories are created using their GUIDs in the filesystem, while the actual GUID <-> name mapping exists only in the index. + LMTP proxy: Implemented XCLIENT extension for passing remote IP address through proxy.

[Dovecot] Bug when a duplicated file is found
by Angel L. Mateo 25 Feb '13

25 Feb '13

Hello, Last days we had to restore some mailboxes from backup. Our mailboxes are in maildir format and during restore, some duplicated files appeared. The situation is: * A user has messages in his new directory when the backup is made * In some moment after the backup is done, the user accesses to his mailbox, so the message is move to the cur directory. * We restore his mailbox directly to his maildir path, so the message is now at new directory too. When this happens, dovecot detect it and it renames one of the files. This is the reported log: Feb 13 23:08:05 myotis31 dovecot: imap(<user>): Warning: Fixed a duplicate: /home/alumnos/59/122559/Maildir/cur/1360169810.M670208P13643.myotis31,S=6282,W=6409:2, -> 1360793285.M721935P29136.myotis31 The problem with this is that we are using zlib plugin so messages are compressed. When the rename is done, the rename is to a name without the S=XXXX field (neither the W=XXX, although this field is less sensible), so the result is that user's can't access to any message after this one. I think than in this situation, rename one of the files is a good solution (although it provokes duplicate mails, but this an expected/acceptable situation after the restore), but the rename should maintain the S= and W= fields (and even other maildir flags). -- Angel L.

[Dovecot] SSL errors for just one client after updaing both dovecot and openssl
by Charles Marcus 25 Feb '13

25 Feb '13

Hi all, Ok, I have a strange problem after updating both dovecot and openssl... OpenSSL was 1.0.0j, now updated to 1.0.1c Dovecot was 2.1.13, now updated to 2.1.15 I'm getting a bunch of lines like the following: Feb 23 10:48:01 myhost dovecot: imap-login: Disconnected (no auth attempts in 29 secs): user=<>, rip=#.#.#.#, lport=993, TLS handshaking: SSL_accept() syscall failed: Connection reset by peer, session=<In+cO2bWngCthJz2> where only the session id (and number of seconds for no auth attempts) is different... This is happening for only the one client. All other clients - I've counted about 25 so far - are working fine. Anyone have any ideas? I can't believe it is a generic openssl problem, since it is only affecting the one client. I've contacted him and asked him to reboot any/all devices that connect to our mail to see if that helps... -- Best regards, */Charles/*

[Dovecot] understanding namespace configuration
by btb＠bitrate.net 25 Feb '13

25 Feb '13

i'm a little confused about namespace configuration. reading http://wiki2.dovecot.org/Namespaces , and looking at the examples, it seems that when a namespace is declared, you can either do "namespace { ..." or "namespace foo { ..." - i'm having trouble finding clarity on the significance of "foo" though. it would appear it's not required, but then what is its purpose? what does it mean? does it imply something? it's also unclear to me how to create the "default private namespace". i see that there are three types of namespaces, but the list of namespace settings doesn't seem to include a parameter to set the namespace type. what am i missing? it's also not quite clear how to denote a namespace as "default". from coming across this thread [ http://mailman2.u.washington.edu/pipermail/imap-protocol/2010-May/001077.ht… ] it would indicate in theory that a namespace is denoted as default by using an empty prefix - but i wasn't able to find corroboration of that in dovecot's documentation. thanks -ben

[Dovecot] Possible sort optimization (?)
by Michael M Slusarz 25 Feb '13

25 Feb '13

Maybe this is just noise... but I can reproduce this fairly reliably. Mailbox with 21,000+ messages This query: a UID SORT RETURN (ALL COUNT) (DATE) UTF-8 SUBJECT "foo" is always about 10 percent slower than this split query (I've done this 4-5 times, and the numbers are similar): a UID SEARCH RETURN (SAVE) CHARSET UTF-8 SUBJECT "foo" b UID SORT RETURN (ALL COUNT) (DATE) UTF-8 UID $ (The particular query I used matched 5 messages out of the 21,000+) My not-very-scientific benchmarking process: 1.) Stop dovecot process 2.) Delete all dovecot index files for that mailbox 3.) Flush linux paging cache (sync && echo 3 > /proc/sys/vm/drop_caches) 4.) Restart dovecot 5.) Access dovecot via command-line (PREAUTH) 6.) SELECT mailbox 7.) Issue command(s) Could be a potential area for performance improvement or could simply be lazy benchmarking. michael

[Dovecot] Problem with the command hooks api
by Tony 24 Feb '13

24 Feb '13

I have been trying to use the command hook api in an experimental plugin I have written. The hook is registered using the command_hook_register function, and for most commands my hook functions get called once as expected. But when the client uses one of the "UID" commands (e.g. "UID FETCH" ) the hook functions are executed twice. I am using dovecot version 2.1.12. Am I correct in thinking this is a bug? If I am wrong and this is the intended behaviour, how should I detect whether the hook function call is the first or second for a client's command (in particular for the 'post command' hook)? Assuming it is a bug, I modified the code in the command_exec function to stop the second hook call, a patch for this is below. This appears to apply to later dovecot releases as well.

[Dovecot] LMTP logging
by Peter Rindfuss 24 Feb '13

24 Feb '13

Hi, Is there a way (in Dovecot 2.1.14) to sent LMTP log entries and IMAP log entries to different files? I know I could achieve this with syslog-ng, but as LDA has a log file of its own, I am wondering if this is possible with LMTP as well. I apologize if I missed something in the wiki. Thanks, Peter

The fact that the same certificate works for other clients, and also for TLS on Thunderbird seem to suggest Thunderbird is fumbling it. But maybe you can try the command diagnostic from the command line "openssl s_client -connect yourserver:993 ..." or use one of the online certificate checkers to get some useful diagnostics. > TLS: SSL_read() failed: error:14094418:SSL > routines:SSL3_READ_BYTES:tlsv1 alert unknown ca This error entry pops up in my logs once in a while. I think the error might be misleading since the error message happen in the middle of a long sequence of successful connections. Also check that the client is actually using the right security mode (not TLS or clear), perhaps by doing a network snoop. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] doveadm user error messages
by Thomas Leuxner 22 Feb '13

22 Feb '13

I use 'doveadm user' in some scripts and the exit codes are fine for my purposes. During tests it transpired that Dovecot 2.1 would give an error message when querying for non-existent users. Dovecot 2.2 just exits without a word. Not sure this is intended behaviour: $ doveadm user foo $ echo $? 67 $ id foo id: foo: No such user Regards Thomas

[Dovecot] pop3_lock_session and mdbox format
by Ewald Dieterich 22 Feb '13

22 Feb '13

Setting "pop3_lock_session = yes" in the configuration has no effect when I use Dovecot 2.1.13 with the mdbox format. A second POP3 connection to the same mailbox is still allowed. Grepping for MAILBOX_FLAG_KEEP_LOCKED in the source code shows that POP3 session locking only works for the Maildir and mbox formats. Is it possible to enable it for the mdbox format, as well? Ewald

[Dovecot] Trouble with expire plugin
by Gedalya 22 Feb '13

22 Feb '13

Hi all, Maybe someone here can help me with this problem, not sure if this is a configuration issue or an actual bug. my daily cron job says: #!/bin/sh doveadm expunge -A mailbox Junk savedbefore 14d doveadm expunge -A mailbox Trash savedbefore 30d doveadm expunge -A mailbox "Trash.*" savedbefore 30d But it hasn't been deleting any messages in a long time, I'm not sure when it stopped working. I've also noticed that it does delete matching rows in the expires database (expire_stamp < savedbefore days). Furthermore, rows are deleted even when running doveadm search, and regardless of the mailbox column, i.e. even when != the mailbox name being searched! Anyway why should doveadm search delete rows in the expires database?
