2.2.15 Panic in mbox_sync_read_next_mail()
by Hans Morten Kind 27 Nov '14

27 Nov '14

It might not be a fault in dovecot, as the user is accessing the folder locally with alpine while also running imap-sessions. However it would have been nice with a more graceful action than panic? The panic is preceeded by Error: Next message unexpectedly corrupted in mbox file PATH Panic: file mbox-sync.c: line 152 (mbox_sync_read_next_mail): assertion failed: (sync_ctx->input->v_offset != mail_ctx->mail.from_offset || sync_ctx->input->eof) At #7 in the enclosed backtrace the actual values are sync_ctx->input->v_offset = 564 mail_ctx->mail.from_offset = 564 sync_ctx->input->eof = 0 Some will recommend convertion to maildir, but with 25 years history, thousands of active users and dozens terrabytes of mboxes, we are not even considering it. hmk GNU gdb 6.8 Copyright (C) 2008 Free Software Foundation, Inc.

Pigeonhole, vacation being sent incorrectly
by Harry Mills 26 Nov '14

26 Nov '14

Hi, I have an issue with a vacation message in a sieve script. I can't see an error in the script itself. Pigeonhole version: 0.4.2-32 Dovecot Version: 2.2.10 The script was created by Ingo (part of the Horde suite), but I think the script is fine. The problem is that when a message is sent to the "everyone" group (and alias for every person in the organisation), vacation messages are being sent back which I believe is an error. The script is: =============================================== # Sieve Filter # Generated by Ingo (http://www.horde.org/apps/ingo/) (11/11/14, 5:20:06 pm GMT) require ["vacation", "regex", "fileinto"]; # Vacation if allof ( not exists "list-help", not exists "list-unsubscribe", not exists "list-subscribe", not exists "list-owner", not exists "list-post", not exists "list-archive", not exists "list-id", not exists "Mailing-List", not header :comparator "i;ascii-casemap" :is "Precedence" ["list", "bulk", "junk"], not header :comparator "i;ascii-casemap" :matches "To" "Multiple recipients of*" ) { if header :regex "Received" "^.*(2014) (\$.*\$ )?..:..:..

I cannot see the address for "user2(a)example.com" in any of those fields, or indeed referenced anywhere in the email. Is this a bug, or am I misunderstanding something?

imap-login segfaults when using post-login
by Nico Rittner 26 Nov '14

26 Nov '14

hello, i get these lines in syslog when using post-login within imap-login: imap-login: Fatal: master: service(imap-login): child 574 killed with signal 11 (core dumps disabled) imap[5523]: segfault at 14 ip b7556276 sp bfc1c940 error 4 in libdovecot.so.0.0.0[b7529000+d4000] these are the relevant sections i added: service imap-login { executable = imap post-login } service post-login { executable = script-login /path/to/exec } i also used /bin/true as /path/to/exec to exclude the used exec itself as the reason. same result. version is 2.2.13 on gentoo-linux. i wonder if this error is gentoo-specific (cflags/etc...) or a bug in dovecot. this behaviour can be reproduced on two other of my gentoo-machines. same configuration worked in previous versions, don't know the exact version number. thanks a lot for your suggestions. i'll also cc to the gentoo-people. nico

Sieve counterpart of IMAP SPECIAL-USE

Hi, It would be useful to allow Sieve scripts to "fileinto" based on SPECIAL-USE flags. But all I've been able to find about it is this: http://www.ietf.org/mail-archive/web/sieve/current/msg05171.html Has there been any progress since? /Peter

slow incremental indexing of maildirs with squat
by vitalif＠yourcmc.ru 26 Nov '14

26 Nov '14

Hi! I'm using Dovecot 2.1.7 on Debian Wheezy 32-bit (package version is 1:2.1.7-7+deb7u1) with maildirs. My problem is that the incremental indexing of maildirs with squat takes a very long time... I don't know if it reindexes anything, but it seems it iterates though all messages on each search query and reads them. It works fast only on successive queries within several minutes, probably because of the messages being in cache. What do you think, is it a bug? -- With best regards, Vitaliy Filippov

Shared mailboxes using SQL
by Daniel Miller 26 Nov '14

26 Nov '14

I recently tried to change from the simple file to a SQL dictionary for ACL. While the Wiki instructions seemed fairly clear I was having errors. After some further digging, and a little thinking - I read the errors and tried to infer what was happening. I have some IMAP groups configured for sharing. And I guessed the example dictionary didn't allow for them. Looking at my existing shared-mailboxes.db flat file I saw something that gave me a clue. So I added the following: map { pattern = shared/shared-boxes/group/$to/$from table = user_shares value_field = dummy fields { from_user = $from to_user = $to } } And things started working again! A suggestion that perhaps this be added to the wiki - possibly with a bit more information on the "map" sections. Also - would there be any benefit to setting up a separate SQL table for groups? -- Daniel

v2.2.14 released
by Timo Sirainen 26 Nov '14

26 Nov '14

http://dovecot.org/releases/2.2/dovecot-2.2.14.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.14.tar.gz.sig Looks like it took a bit longer to make this release after RC1 than I thought. I'm now in San Jose area for a few months and still jumping between apartments and trying to adjust to the new timezone. Some of the more important fixes since RC1: - Fixed several race conditions with dovecot.index.cache handling that may have caused unnecessary "cache is corrupted" errors. - auth: If auth client listed userdb and disconnected before finishing, the auth worker process got stuck (and eventually all workers could get used up and requests would start failing). Some of the larger changes since v2.2.13: * lmtp: Delivered-To: header no longer contains <> around the email address. Other MDAs don't have it either. * "Out of disk space" errors are now treated as temporary errors (not the same as "Out of disk quota"). * replication plugin: Use replication only for users who have a non-empty mail_replica setting. + lmtp proxy: Log a line about each mail delivery. + Added login_source_ips setting. This can be used to set the source IP address round-robin from a pool of IPs (in case you run out of TCP ports). + Rawlog settings can use tcp:<host>:<port> as the path. + virtual plugin: Don't keep more than virtual_max_open_mailboxes (default 64) number of backend mailboxes open. + SSL/TLS compression can be disabled with ssl_options=no_compression + acl: Global ACL file now supports "quotes" around patterns. + Added last-login plugin to set user's last-login timestamp on login. + LDAP auth: Allow passdb credentials lookup also with auth_bind=yes - IMAP: MODSEQ was sent in FETCH reply even if CONDSTORE/QRESYNC wasn't enabled. This broke at least old Outlooks. - passdb static treated missing password field the same as an empty password field. - mdbox: Fixed potential infinite looping when scanning a broken mdbox file. - imap-login, pop3-login: Fixed potential crashes when client disconnected unexpectedly. - imap proxy: The connection was hanging in some usage patterns. This mainly affected older Outlooks. - lmtp proxy: The proxy sometimes delivered empty mails in error situations or potentially delivered truncated mails. - fts-lucene: If whitespace_chars was set, we may have ended up indexing some garbage words, growing the index size unnecessarily. - -c and -i parameters for dovecot/doveadm commands were ignored if the config socket was readable. - quota: Quota recalculation didn't include INBOX in some setups. - Mail headers were sometimes added to dovecot.index.cache in wrong order. The main problem this caused was with dsync+imapc incremental syncing when the second sync thought the local mailbox had changed. - doveadm backup didn't notice if emails were missing from the middle of the destination mailbox. Now it deletes and resyncs the mailbox.

Possible to adjust username used to determine the proxy destination?
by Andy Dills 25 Nov '14

25 Nov '14

I'm in a fairly standard cluster environment: shared storage, bunch of servers each acting as both proxies and backends. We do /bin/checkpassword authentication, allowing a great deal of flexibility...protection against brute force, billing mechanisms, but relevant to this issue, I have it set up to allow users to login with either their username (if they are in one of our default domains) or their email address. I'm realizing now that as a consequence of this, "joe" and "joe(a)xecu.net" are unique as far as dovecot is concerned. Users who login with just their username (and not the full email address) can get assigned to a different backend server than when they login with the full email address (which would also include LMTP deliveries). This has been happening for years, a few broken indexes here and there that seem to resolve themselves, so it hasn't been impacting the service, but I'd like to correct it properly. Is there a way to manipulate this? For example, if I moved the authentication to the proxy layer (it's currently proxy=y nopassword=y), and set $ENV{USER} to the full email address, will director use that for selection instead of the user-supplied username? I'm open to suggestions on how best to accomplish this. Thanks, Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

doveadm backup for all users to file system
by Jeff Larsen 24 Nov '14

24 Nov '14

The wiki says that doveadm backup supports the -A option for all users, but when I specify a file-system destination (like /tmp, or an NFS mounted folder), it just rewrites each user backup to the same location overwriting the previous user's content. You end up with just the content for the last user processed. I tried the typical %u substitution but that just created folder named '%u' and had the same overwrite problem. My userdb is LDAP which works just fine for other doveadm commands. The verbose/debug output from doveadm backup shows that it is processing every user. Example: doveadm -vD backup -A sdbox:/tmp/backup My understanding is that "doveadm backup" is just a front-end for dsync. The dsync manpage on the other hand says "dsync can currently sync only one user at a time. If you want to dsync all users, you'll need to get a list of all users and execute dsync separately..." It appears that "doveadm backup -A" is doing the iteration for me, but it's not generating individual destination paths for each user. So, is this is a documentation problem for "doveadm backup"? Or am I missing something here? Is there some secret sauce for "doveadm backup -A" that I'm not finding? If all else fails, I know I can write a script to iterate over the available users and run the backup repeatedly, but I would like to keep this as simple as possible. Thanks, Jeff

Outlook 2010 not connecting to secure POP3
by Robert Moskowitz 24 Nov '14

24 Nov '14

OK, I did not know that this user has a new computer with Outlook 2010. This SHOULD make it easier but... I have the computer right next to me, they brought it over. It is on the same LAN as this notebook. I can access my server with: openssl s_client -connect z9m9z.htt-consult.com:995 And then log the user in with the appropriate POP3 credentials. In Outlook 2010, in Advanced settings I have specified "This server requires an encrypted connection (SSL)" and it switches to port 995 (from 110). I try connecting and I get an error that "Your server does notg support the connection encryption type you have specified." The first time we tried this it installed my self-signed cert in the local cert store. Any idea on what is going on or how to get this working?

Strange repplication issues
by Bertrand Caplet 24 Nov '14

24 Nov '14

Hi, I know there are lots of questions about replication, but I searched and didn't find my question. I've got some problems with syncing. I've got 2 servers: A and B When a email arrives on server A sometimes it's not syncing in server B I think server A doesn't always notify server B there are new mails to sync. But I don't know how to fix it. And I spotted something, when it isn't syncing. The only thing to do is to send local or remote mail to server B and then it sync or do a "doveadm sync -A tcp:serverB.example:port" of course. My doveconf -n of the two servers are in attachements bellow. By the way both of my dovecot servers are v2.2.9 P.S.: I didn't test from server B to A but I think it's the same problem.

by Rajesh M. 23 Nov '14

23 Nov '14

hi i am using dovecot for pop3 and imap along with qmail toaster i had recently changed over from a 32 bit system to a 64 bit system. i use squirrelmail. the issue i face is that when the user inserts an invalid password then the message he gets is connection dropped by imap server (instead of invalid userid or password) such a message confuses the user. my earlier 32 bit version used to give the correct message i am posting this issue here because i am not sure if this is squirrelmail issue or a dovecot issue. can somebody please let me know the reason for this ? rajesh

Migrate Separator and prefix
by Hanns Mattes 23 Nov '14

23 Nov '14

Hi, I'm thinking of changing the separator form "." to "/" and also to allow only folders under INBOX, changing the Prefix. I have to dovecot-servers, which are synched by the replication plugin. My idea is to switch off Server B, make the necessary config-changes, delete all user maildirs, restart the server an let replication do it's work. After that (and correcting the sieve-rules of the users if necessary), I'd stop server A, delete, restart, resync. My idea is, that this will avoid dealing with subscriptions files and change them to reflect the new INBOX-Structure. Is this going to work at all and/or is there a better way for the wanted migration? Thanks in advance Hanns

Outlook Express and STARTTLS
by Robert Moskowitz 23 Nov '14

23 Nov '14

I have one user that uses Outlook Express. Not only do I not use it, I don't have any systems here that can easily use it. I bit of a challenge. I am strictly enforcing STARTTLS or TLS for SMTP/POP3/IMAP connections. SO far a google search has not shown me how to configure this for a user. Anyone have a pointer to instructions so I can talk the person through the changes?

Prevent a message from be deleted but not from be moved
by Bruno Galindro da Costa 22 Nov '14

22 Nov '14

Is it possible to prevent a message from be deleted but not from be moved to another mailbox via ACL? I need this because I'm using antispam plugin with the mailtrain backend. It calls a script every time a message is moved to/from a monitored spam mailbox. But, if the user deletes a message from the spam folder, the script is executed with the option to train the antispam to consider that excluded message as a non spam. So, what I need is to prevent the user from delete a message from the spam mailbox, but I want to permit the user to move a menssage from the spam mailbox to another mailbox. -- Att.

You have the directory entries .dovecot.sieve and .subscriptions, which is anyway a directory indeed, so that's not even a bug. Move all your maildirs to /home/mail/%d/%u/Maildir and then update mail_location accordingly. Then move out the sieve files - .dovecot.sieve, sieve/, .dovecot.sieve.log, .dovecot.svbin to the home directory.

There are a number of funny things here. First of all, dovecot.sieve belongs in the *home* directory, not in Maildir. The home directory can be, typically, the parent directory of the Maildir. Like in: domains/example.com/user1/Maildir - the user1/ is the home directory and dovecot.sieve lives there. Would you please post your complete dovecot config (output of the command: dovecot -n) and also an example output of ls -la of your directory structure? See also http://dovecot.org/mailinglists.html
