[Dovecot] IMAP copy fails because the mailbox size of user1 is exceeding the quota limit of user2??
by Katja Wegner 05 Jun '14

05 Jun '14

Hi all, I do have a mailbox-quota problem in dovecot 2.0.19 that is beond my understanding. Could someone pls. give me a hint. - user1 max. mailbox quota is set to 1GB, the current mailbox size of user1 is 15MB - user2 max. mailbox quota is set to 10MB, the current mailbox size of user1 is 10kB - user1 shares the folder 'shared_folder' to user2 with all rights (read, write ...) - user2 has subscribed to 'shared_folder' the problem: - user2 tries to move a mail (20kB) to the shared folder via telnet: ". copy 1:1 shared/user1/shared_folder" - it fails with: "NO [OVERQUOTA] Quota exceeded (mailbox for user is full)" - copying the same mail to a local folder of user2 works without problems. - After I raised the max. mailbox quota of user2 from 10MB to 16MB it was possible to move the mail to the 'shared_folder' of user1. It looks like the copy operation fails because the mailbox size of user1 is exceeding the quota limit of user2! Is this possible? Is this a bug?

[Dovecot] attachment sis + EMLINK (too many links) = segfault bug (2.2.12)
by Pavel Stano 05 Jun '14

05 Jun '14

Hi, we use attachment dedup with lots of emails (still migrating to it from maildir). We use netapp storage with wafl filesystem over nfs. Problem is that netapp has hard limit of 100k hardlinks to one file. And we encountered it. Problem is that dovecot start do segfault (lmtp,dsync,pop3 etc) when it happend when tried to deliver new emails with that attachment. Here is strace of dsync: 6740 link("/nfsmnt/mailatch1/f9/10/hashes/f9108ddaa156ac15738e41ed3bedec1eda50175d", "/nfsmnt/mailatch1/f9/10/f9108ddaa156ac15738e41ed3bedec1eda50175d-7bb7a20ddb598853541a000028db4a9f") = -1 EMLINK (Too many links) 6740 --- SIGSEGV (Segmentation fault) @ 0 (0) --- ls -lh: -rw------- 100000 vmail vmail 4.7K Apr 28 16:54 /nfsmnt/mailatch1/f9/10/hashes/f9108ddaa156ac15738e41ed3bedec1eda50175d We were using mail_attachment_min_size=4kb, we solve it by increasing it to 8kb. It would be nice to somehow fix this problem. Like not crash when EMLINK happend and maybe do not deduplicate attachments but deliver email without dedup. Or create second file in hashes/ and start hardlinking it instead of original. AFAIK ext4 has also hard-link limit 64k (http://en.wikipedia.org/wiki/Hard_link#Limitations_of_hard_links) So this can happen to anyone with lots of emails.

[Dovecot] Plugin mail-filter tangles
by Stanislas SABATIER 05 Jun '14

05 Jun '14

System installed : Dovecot 2.2.12 as IMAP server and Postfix as MTA. Dovecot and Postfix connected via LMTP + Dovecot mail plugin 'mail-filter' to encrypt/decrypt emails on the fly with public/private users' RSA keys. Case study : You have 3 (virtuals) users belonging to 3 different domains, all managed by your Dovecot server. One of these users is connected to Dovecot with MUA Thunderbird, and he's writing an email to someone outside of yours domains, but he puts the two others users' email addresses in CC : mail from user1(a)domain1.dovecot --> to: someone@outside, CC: user2(a)domain2.dovecot, user3(a)domaine3.dovecot What happens (as far as I can understand) : The email is submitted to Postfix : one copy is delivered outside, the other is passed to Dovecot via LMTP for user2 & user3 @dovecot Dovecot is handling the final delivery, through mail-filter plugin as follow : 1. both users contexts are created from user_db queries 2. mail-filter plugin is init for user2 3. /mail_user_created/ for user2 4. mai-filter plugin arguments are parsed for user2 5. â¦/mail_allocated/ then /mail_save_begin/ for user2 (at this stage, the email is encrypted with users2 params) 6. Dovecot tells to LMTP that mail for user2 is delivered 7. then, â we are still in user2 context â, an other /mail_allocated/ is run, followed by a /istream_opened/ 8. mail user context is swithed to user3 --> /mail_user_created/ --> plugin's args parsed --> â¦ /mail_allocated/ 9. andâ¦ Dovecot tells to LMTP that mail for user3 is delivered So, it appears that Dovecot is re-using user2's email to pass it to user3 by opening an istream in user2's context. In my configuration, Dovecot can't do that because it has not the user2's private rsa key to reopen the email it has just encrypted, so it passes the email to user3 with user2 encryption params. Final result : user3 is receiving the email encrypted with user2's rsa key ! Problem : how to force Dovecot to deinit then reinit mail-filter plugin for each user to be sure that each email is encrypted with the right key before it is saved to users' mailboxes ? Thank you in advance for your help. Stan.

[Dovecot] SQL passdb, LDAP userdb
by Kristof Bajnok 05 Jun '14

05 Jun '14

Hi, in my current setup, LDAP authentication + userdb works fine. I'd like to integrate Dovecot with Shibboleth. I have a custom module at the IdP (*) that inserts short-time tokens to an SQL table at user authentication, and I want Dovecot to use the token table for passdb but keep LDAP for storing the userdb (uid, quota, etc) I thought it was simple as omitting the sql user_query, but I got: Warning: mysql: Query failed, retrying: Table 'webmail.users' doesn't exist Error: sql(user@domain,ipaddr): User query failed: Table 'webmail.users' doesn't exist (using built-in default user_query: SELECT home, uid, gid FROM users WHERE username = '%n' AND domain = '%d') Do you have any hints how to do this? Thanks, Kristof (*): in SAML there is an Identity Provider that does user authentication, which is separated from the services

UID 26624 is a valid user ('info' of domain14552) but under a compleltly different domain name (hamish is under domain25367). However that user has also not logged in around the time the ownership was changed. There is no relevance to the two users, except that they exist on the system and for some reason this issue happened to the hamish user. The NFS server does not know about the UIDs, it just provides the numeric IDs which is translated on the dovecot/exim servers by NSS and Dovecotr using the replicated MySQL database. Additionally both users have existed for some time and the databases are in sync. Customers also do not have any access to the file system so there will be no symlinks in place. Its also not a single server that we are seeing the issue on, it maybe one Dovecot server accessing one NFS server. Then the next time its a different Dovecot server accessing a different NFS server. >> >the logs for that time which is abnormal (a whole bunch of other logins from >> >other customers but nothing from those two users and no errors) > What about cron jobs, message delivery, backups, ... anything that > possibly can alter that file. I don't think, it's a Dovecot issue, unless > the uid 26624 is valid and hamish is shared with that user. Nothing besides Courier being replaced by Dovecot has changed in the server setup (although I could be wrong there, but we are going through one component at a time and until this issue is resolved we are not moving onto the next), and the only file which is being modified is a file which only Dovecot maintains. There are hourly backups which do an rsync to another server in case of hardware failure, there are scripts which move mailboxes between NFS servers but they show up in logs. Exim has no need to touch a dovecot controlled file, and when it writes mail into the maildir its writing as the correct user. It also seem odd that one login is fine then randomly the next login the file ownership has changed, nothing happens in between the two logins which are in some cases only 5 to 10 minutes apart. All I am really looking for is ideas on where to look, as it seems odd that nobody else is reporting this, and since its a reasonably new setup its possibly something we have done in the config (which I posted in my first email). Is there a reliable way to run a script directly when a dovecot session starts and finishes so we could output the ownership before and after which may also help eliminate the session itself. Cheers, Bruce

[Dovecot] empty emails with 2.2.13/pigeonhole
by Cor Bosman 04 Jun '14

04 Jun '14

I recently upgraded from 2.2.10 to 2.2.13, and also upgraded pigeonhole. Ever since im seeing some empty emails appear in my inbox. Return-Path: <cricket(a)stats2.xs4all.net> Delivered-To: <cor> Received: from imapdirector1.xs4all.net ([194.109.26.173]) by userimap9.xs4all.nl (Dovecot) with LMTP id CHu0MUDDjlOBdwAAwvsqNQ for <cor>; Wed, 04 Jun 2014 08:57:04 +0200 Thats all this mail contains. This only happens using LMTP/Sieve, and with many different senders/recipients. Debug log shows nothing out of the ordinary, except that the mail seems to be corrupted by the time it hits sieve. It's very hard to diagnose. Our path is kind of lengthy, and in theory it could happen everywhere. Mail first arrives on incoming MX server which is sendmail. From there it's sent to a dovecot director using lmtp, which sends it to a server that does final delivery with sieve. Im not sure where the email gets corrupted. Any extra debugging I could turn on? Two extra things to note. So far it seems to only happen to emails that would have hit a matching sieve filter rule. I have asked a dozen people to verify this, and all emails would have matched a filter if all was well. Instead, it gets dropped into the inbox because pigeonhole seems to be working with the corrupt file and cant match any rules anymore. And second, 99% of our email is handled differently, from the sendmail server directly into a local mailer, and that never causes issues. We're in the process of switching to lmtp. Any insights? cor

[Dovecot] /etc/passwd userdb and long usernames
by Nicolás Reynolds 04 Jun '14

04 Jun '14

hi! i've configured dovecot to lookup usernames in /etc/passwd and it's working ok but it's having some problems retrieving info when the username is longer than 32 chars (i know it isn't recommended but everything seemed to work ok except for the hardcoded limit in useradd...) i found this on logs showing extra characters on the home field: http://pastie.org/pastes/9257902/text?key=vsxstofu3rf5wum4aic5va is there a limit on username length? i "solved" it by setting auth_username_format = %0.30u -- http://partidopirata.com.ar

[Dovecot] Dovecot + NFS + FreeBSD breakage ?
by Xavier Beaudouin 04 Jun '14

04 Jun '14

Hi, I am trying to update my old mails servers from dovecot 2.1.15 to 2.2.12 (freebsd ports) and upgrade to FreeBSD 10.0-P3. My mail storage are on NFS with index also. On 2.1.15 everything is ok, and in 10-mail.conf I have the good things to be added as wiki tell me (eg http://wiki2.dovecot.org/NFS) BUT, when I try a single connection like : $ telnet ::1 110 Trying ::1... Connected to localhost. Escape character is '^]'. +OK Dovecot ready. user test@domain +OK pass thebloodypass Connection closed by foreign host. Looking the log : Jun 4 10:09:10 mail03 dovecot: master: Dovecot v2.2.12 starting up for imap, pop3, lmtp Jun 4 10:09:20 mail03 dovecot: pop3-login: Login: user=<test@domain>, method=PLAIN, rip=::1, lip=::1, mpid=5540, secured, session=<7x47Jf76IQAAAAAAAAAAAAAAAAAAAAAB> Jun 4 10:09:20 mail03 dovecot: pop3(kiwi(a)oav.net): Fatal: nfs flush requires mail_fsync=always This is very strange since : # doveconf -n | grep -E 'sync|nfs' mail_fsync = always mail_nfs_index = yes mail_nfs_storage = yes So either there is some breakage somewhere or something that is buggy somewhere...

[Dovecot] Change in LAYOUT=fs between 1.2.9 and 2.0.19?
by Martijn 04 Jun '14

04 Jun '14

While testing an upgrade from Dovecot 1.2.9 (on Ubuntu 10.04 LTS) to 2.0.19 (12.04 LTS) I encountered the following change in behaviour: In both setups, mail_location is defined as follows: mail_location = maildir:~/domains/%d/%n/.Maildir:LAYOUT=fs No other mail_location-related settings are set in the config. On 1.2.9 this leads to new mail being delivered to this example directory: /home/username/domains/example-domain.ext/webmaster/.Maildir/INBOX/new/ On 2.0.19 the exact same mail_location is set, but new mail is now delivered to: /home/username/domains/example-domain.ext/webmaster/.Maildir/new/ Notice the missing /INBOX/ in the path on 2.0.19. I found no mention of this change on http://wiki2.dovecot.org/Upgrading/2.0 which first lead me to suspect this was a bug in 2.0.19. However, while browsing the 2.0-wiki I found a page which sheds some light on the behaviour that is to be expected from Dovecot 2.0.x. Quote from http://wiki2.dovecot.org/MailLocation/Maildir#Directory_layout > "Mailbox directory name": "Without DIRNAME, INBOX will be stored at ~/Maildir/{new,cur,tmp}/, but when DIRNAME is specified, we get an extra path component INBOX/ immediately prior to the DIRNAME value, so in the example above INBOX would be stored at ~/Maildir/INBOX/mAildir/{new,cur,tmp}/." I then changed mail_location to have an empty DIRNAME, like: mail_location = maildir:~/domains/%d/%n/.Maildir:LAYOUT=fs:DIRNAME= It appears this fixes the problem for new mail arriving (haven't tested other folders yet). Questions: 1. Is this a deliberate change in behaviour between the two versions? If so, may I suggest adding this change to the Upgrading to 2.0 wiki page, because I was unable to find the relevant info quickly. If not, is this a misconfiguration on my side, or a (known) bug in one of the two versions? 2. Is the DIRNAME=(empty) a good solution, or is it unusual/hacky to leave DIRNAME empty? Any particular problems I may expect using this configuration? Thanks in advance for your help. -- Kind regards, Martijn

[Dovecot] Info about sharing mail folder
by Gianluca Calloni 03 Jun '14

03 Jun '14

Hi to all. First of all.. I'm new on the mailing list.. So.. Sorry in advance for any mistake or error on posting here.. The question (or doubt..) is about sharing mail folder. I use a test mail server. Is not the production server (always dovecot + postfix + spamassassin + clamav) Well.. In test mail server i can use the share folder, follow the conf istruction on wiki dovecot. And work fine. But i need to know if is possible for user_a(a)mydomain.com to share only 1 or 2 subfolder (E.g. .INBOX.FOLDER_A and .INBOX.FOLDER_B shared, .INBOX_FOLDER_C not shared) When i do some test sharing folder, the user with wich user_a(a)mydomain.com share the mailbox can view all the subfolder of user_a(a)mydomain.com Following my dovecot versione e config. Thank's in advance My dovecot version is 2.0.19 My dovecot conf is : # 2.0.19: /etc/dovecot/dovecot.conf doveconf: Fatal: open(/etc/dovecot/dovecot.conf) failed: Permission denied calloni@dovecot:~$ sudo -i [sudo] password for calloni: root@dovecot:~# dovecot -n # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.5.0-49-generic i686 Ubuntu 12.04.4 LTS ext4 dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no first_valid_uid = 150 last_valid_uid = 150 mail_gid = mail mail_location = maildir:/var/vmail/%d/%u mail_plugins = acl mail_uid = vmail namespace { inbox = yes location = prefix = separator = / type = private } namespace { list = yes location = maildir:%%h:INDEX=~/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile acl_shared_dict = proxy::acl } postmaster_address = postmaster(a)jodovit.local protocols = " imap pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = mail mode = 0600 user = vmail } } service dict { unix_listener dict { group = mail mode = 0600 user = vmail } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } Thi

Not offhand, but if you want a remote tool, it ought to be simple to cobble together some feeder script and netcat (or openssl s_client). It will also be simpler if you configure the master password feature so you don't have access to all user passwords. So something like this for dumping the INBOX contents #!/bin/sh master-user=masteru master-password=masterp while read user server; do netcat --ssl $server 993 <<_EOF_ >${user}.report 1 LOGIN ${user}*${master-user} ${master-password) 2 SELECT INBOX 3 ... 4 LOGOUT _EOF_ done I don't know enough IMAP to fill in "3 ..." to dump all headers, but I'm sure it's not hard to find out. It's even simpler if you don't need to do it remotely: just use doveadm fetch -A hdr MAILBOX '*' Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] list all emails from command line?
by Tomasz Chmielewski 03 Jun '14

03 Jun '14

This is not strictly Dovecot question, but a more general IMAP one. I'm running a Dovecot server and have a user who is claiming that some email sent to him, say, on 30 May, showed up in his mailbox on 02 Jun. I've checked Postfix logs, and the message was correctly received on 30 May and passed to Dovecot. A similar issue happens every few days. This leaves me with two possibilities: 1) Dovecot is somehow not presenting the new mail to the user in a "timely manner" 2) user's email program is broken Therefore, I wanted to do some kind of "IMAP list" of the account, with a command line tool: - specify username, pass and server, - the tool would return a list of all email in their folders (message ID, From, To, Date, Subject). I would run it i.e. daily and this would let me verify when the mail was really visible in the account. Is anyone aware of a tool I could use to achieve that? -- Tomasz Chmielewski http://www.sslrack.com

[Dovecot] dovecot: lda(foo): Error: User foo doesn't have home dir set, disabling duplicate database
by Christian Hoffmann 02 Jun '14

Hello everyone, I have a small problem with dovecot installed on ubuntu-13.10. I use dovcot as LDA with a LDAP-passdb and a pam-passdb. The userdb is static. A mail to LDAP-user 'foo' is delivered with the error-message dovecot: lda(foo): Error: User foo doesn't have home dir set, disabling duplicate database A mail to the pam-user 'bar' will deliverd without this error. But both users should work with the static-userdb. Where is my mistake?

Can someone explain how I can create message rules to use with this version of Dovecot? I specially switched to this version because it supports then Pigeonhole Sieve. I would like to volunteer to contribute as a volunteer when someone would like to create a html driven user interface that provides a user friendly configuration interface and would make such configuration a piece of cake. -- Best regards, Jos Chrispijn --- Artificial intelligence is no match for natural stupidity

[Dovecot] Dovecot 2.1.13: some questions about the mail-filter plugin
by Axel Luttgens 02 Jun '14

02 Jun '14

Looking at mail_filter_mailbox_allocated() of src/plugins/mail-filter/mail-filter-plugin.c: if ((class_flags & MAIL_STORAGE_CLASS_FLAG_OPEN_STREAMS) == 0 && (class_flags & MAIL_STORAGE_CLASS_FLAG_BINARY_DATA) != 0 && muser->out_socket_path != NULL) v->save_begin = mail_filter_mail_save_begin; it seems that a backend with MAIL_STORAGE_CLASS_FLAG_OPEN_STREAMS unset and MAIL_STORAGE_CLASS_FLAG_BINARY_DATA set is expected by the plugin. Technically, this would thus exclude the mbox backend, since its flag configuration seems to be exactly the opposite: struct mail_storage mbox_storage = { .name = MBOX_STORAGE_NAME, .class_flags = MAIL_STORAGE_CLASS_FLAG_MAILBOX_IS_FILE | MAIL_STORAGE_CLASS_FLAG_OPEN_STREAMS | MAIL_STORAGE_CLASS_FLAG_HAVE_MAIL_GUIDS, [...] Is this a correct interpretation? If yes, what is the rationale? I couldn't find any info related to such a limitation in the docs; the README file of http://dovecot.org/patches/2.2/mail-filter.tar.gz even says: "Mail filter plugin can read an email from any storage supported by Dovecot and modify the mail in some way"... All of this stems from my attempts to have working mail filters when I was trying to better understand the behaviors Stanislas was describing in a recent thread... Hence another question; in sdbox-storage.c, the definition of the "alias" for sdbox comes with: struct mail_storage dbox_storage = { .name = "dbox", /* alias */ .class_flags = MAIL_STORAGE_CLASS_FLAG_FILE_PER_MSG, [...] The initialization of member class_flags seems to be incomplete, when compared to the one for the name "sdbox". A typo? On the other hand, Stanislas showed a configuration with mail_location = dbox:/mailboxes/%Ld/%Ln and seemed to have a working mail filter. If above interpretation is correct, this would mean that the "alias" definition isn't used, but that the one for "sdbox" is used instead. Out of curiosity, how/where is that substitution achieved? Regards, Axel

[Dovecot] Combining userdbs
by Bubreg István 01 Jun '14

01 Jun '14

Hi, I think that using more than one userdb with setting the result actions doesn't work as expected from the documentation. The goal would be to set user-specific quotas for a few users with a specific passwd-file like this : cat /etc/dovecot/quotas foo:x::::::userdb_quota_rule=*:storage=2G The first userdb is passwd (with pam passwd): userdb { driver = passwd result_failure = return-fail result_internalfail = return-fail result_success = continue-ok skip = never } The second one is for the specific quota userdb { args = username_format=%n /etc/dovecot/quotas driver = passwd-file result_failure = continue result_internalfail = continue result_success = return-ok skip = notfound } User 'foo' exists in (pam) passd, but there's no place to store his own quota rule, that's why came handy to use a second userdb for storing just one extra field. That's working quiet well, he default quota is overriding form passwd-file. BUT: I've played a lot with changing the result_* and the 'skip' parameters, but none of them worked in the situation where a user ('bar') _only_ exists in passwd (and has to use the default quota config). doveadm quota get -u bar says doveadm(bar): Fatal: User doesn't exist With changing the parameters this error has gone, but the second userdb doesn't used for user 'foo' - even if the parameters are : userdb { driver = passwd result_failure = return-fail result_internalfail = return-fail result_success = continue <-- in theory, the next userdb is coming skip = never } userdb { args = username_format=%n /etc/dovecot/quotas driver = passwd-file result_failure = continue result_internalfail = continue result_success = return-ok skip = notfound } My question is that how should i set the result_* and 'skip' parameters to solve this : - there's a default quota rule in the config - some (a few) users has a larger quota - there's no way to store the user-specific quotas in the 'real' userdb (because it's pam/passwd) Thank you for your effort. # dovecot -n # 2.2.13 (de9b10f2e168): /etc/dovecot/dovecot.conf # OS: Linux 3.11.0-15-generic i686 Ubuntu 12.04.4 LTS auth_debug = yes auth_debug_passwords = yes auth_verbose = yes auth_verbose_passwords = yes disable_plaintext_auth = no listen = * log_path = /var/log/dovecot.log mail_debug = yes mail_location = maildir:~/Maildir mail_plugins = " quota" managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave duplicate 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 = } passdb { driver = pam } plugin { quota = maildir:User quota quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap sieve" service managesieve-login { inet_listener sieve { port = 4190 } } service managesieve { process_limit = 1024 } ssl = no ssl_cert = </etc/dovecot/private/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = passwd result_failure = return-fail result_internalfail = return-fail result_success = continue-ok } userdb { args = username_format=%n /etc/dovecot/quotas driver = passwd-file result_failure = continue-ok result_internalfail = continue-ok skip = notfound } protocol imap { mail_plugins = quota }

[Dovecot] Disabling plus sign extension delimiter in lmtp listener (or userdb)
by Benoit Panizzon 01 Jun '14

01 Jun '14

Hello We have migrated our email services from a server, which did not support IMAP and folders, therefore threated the plus sign + as a normal character in a part of an email address. Our new server delivers the emails via lmtp to dovecot. the few users which got a + character in the username first could not log-in (fixed by adding + to auth_username_chars). Now the next problem turn out to be, that the lmtp listener stripps everything after the + sign. The MTA correctly sends the whole email address, so it's not the MTA's fault. It can easily be tested by connecting to the dovecot LMTP listener IP address by telnet: 220 grautvornix.imp.ch Dovecot ready. mail from:<nobody> 250 2.1.0 OK rcpt to:<b+enoit(a)iscan.ch> 550 5.1.1 <b+enoit(a)iscan.ch> User doesn't exist: b(a)iscan.ch I could not find any configuration parameters for the lmtp listener or userdb service to tell it what to do with the + sign. Did I miss something, or is it impossible to have the + sign accepted as a normal character in an email address? Kind regards -Benoit-

[Dovecot] Upgraded my dovecot?

I upgraded my server from Ubuntu 12.04LTS to 14.04LTS and it upgrade my dovecot too. Probably should have thought about that a little more before I pushed the button but oh well. So it didn't work when it came back up and I had to add a "inbox=yes" line to my namespace in 15-mailboxes.conf and that fixed it. So is there anything else I should update in my config files for this newer version of dovecot? # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-30-generic x86_64 Ubuntu 14.04 LTS auth_mechanisms = plain login mail_location = mbox:~/mail:INBOX=/var/mail/%u 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 = } passdb { driver = pam } protocols = " imap" service imap-login { inet_listener imaps { port = 0 } } service pop3-login { inet_listener pop3 { port = 0 } inet_listener pop3s { port = 0 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { imap_capability = IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS mail_max_userip_connections = 30 } Thanks,

I have a user with with W7/TBird/IMAP to my dovecot 2.1.17 server, the user complains whilst he is composing lengthy emails (with multiple fowrds/replies quoted in the message) he gets 'hour glass' over compose windows with some message about not being able to save drafts, he then powers off ADSL modem, which enables him to continue composing email, powers on ADSL, and sends email what if anything can I assess at server end to identify any issues? any TB tips, what to enable or disable on TB ? looking at dovecot now (past the issue) with 'doveadm who' I don't see the user listed I think the user keeps many messages open concurrently in TB tabs, could that exhaust connection limit ? I expect this to be a TB issue? but, hope for some pointers

Hi there, We recently upgraded to 2.2.12 (the current version in FreeBSD's port tree), and are seeing these errors in our logs (not super frequently, but it happens): May 30 13:20:57 mail1 kernel: pid 15752 (imap), uid 1005: exited on signal 6 May 30 13:20:57 mail1 dovecot: imap(xxx): Fatal: master: service(imap): child 15752 killed with signal 6 (core not dumped - set service imap { drop_priv_before_exec=yes }) I tried manually upgrading to 2.2.13, on the off chance that was fixed, but I couldn't get the new pigeonhole (0.4.3) to compile once I did (perhaps why the FreeBSD port maintainer hasn't updated yet?). Suggestions? Right now we just check every couple of hours for affected users, and then delete all of the dovecot files for the affected user, which ends the error. Thanks, Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

As others have intimated, the use of procmail as your LDA is causing your mailbox to become inconsistent with respect to your indices. Procmail is appending your messages to mailboxes, but is ignorant of the existence of dovecot indices, and does not update them. When your IMAP service access those mailboxes, it detects this condition, and that's the log messages you are seeing. I think those messages are benign -- you can probably ignore it. Dovecot will automatically rebuild them. The alternative is to let dovecot's be responsible for message delivery: it can then update the indices, and IMAP/POP will find consistent indices. Try this at the end of procmailrc for regular delivery to the INBOX ################################################################################ # Replace default action using dovecot-lda to maintains caches. ################################################################################ :0 w | /location/of/dovecot-lda -d $USER For for non-INBOX filtering, try something like :0 Hw *^Subject: TEST |/location/of/dovecot-lda -d $USER -m testbox Joseph Tam <jtam.home(a)gmail.com>

> * ^List-Id:.*users.lists.fedoraproject.org > | $DELIVER -m $DESTDIR/MLists/Fedora You removed the '-d' parameter -- it may or may not work without it, but you'll need it in a virtual user setup. I'm not sure whether procmail sets $USER by itself or it gets passed as an environment variable, so if $USER is not working, use $LOGNAME, or better yet, just hardcode the value if this is your own script. Also, the -m parameter is the name of a mailbox, not a pathname, so I think "MLists/Fedora" is what you want. > This is what I found in the procmail log: > lda: Fatal: destination user parameter (-d user) not given Well, this error couldn't be more explicit, can it?

[Dovecot] dovecot 2.1.15 hangs while connecting.
by Albert Whale 28 May '14

28 May '14

I am using Dovecot in two Server environments. My Legacy (5 years+ old) servers are running dovecot 1.1.20, and are responding as expected. These servers are using an NFS based storage for the /home directory structure, and are working beautifully. However, I need to replace these inefficient servers, and get more current. That brings me to the problem, where I am implementing Dovecot 2.1.15, which does not complete the authentication cycle.

[Dovecot] Corrupted Mail?
by Arthur Dent 28 May '14

28 May '14

Hello All, I have a Dovecot v2.2.12 installation running on a Fedora 20 box which is the mailserver for my family. This means that it is serving only 4 accounts. I use fetchmail->procmail to feed Dovecot and I read my mail on clients such as Evolution on (another) Fedora 20 machine, iPad/iPhone or squirrelmail on the web (running on the same Fedora 20 server). The average mail throughput for the whole family is around a couple of hundred messages per day, but each (and every) day I get between 3 and 10 of the following messages: dovecot: imap(mark): Error: Next message unexpectedly corrupted in mbox file /home/mark/mail/MLists/Fail2Ban at 3407473: 1 Time(s) I have googled, but with little success. What I have found seemed to suggest that removing the .index files and allowing Dovecot to rebuild them will solve this. I did: find /home -type f -name "dovecot.index.*" -exec rm -f {} \; but it has made no difference. Can anyone help me solve this please? Thanks in advance Mark

[Dovecot] dsync changing source permission to "root" in backup mode
by Peter Mogensen 27 May '14

27 May '14

Hi, We have dsync failing once in a while when running in "backup" mode. What's strange is that the result is that the file permissions on the *source* machine ends up with the wrong permissions (set to uid 0). Even though the dsync manual clearly says: "Backup mails from default mail location to location2 (or vice versa, if -R parameter is given). No changes are ever done to the source location. Any changes done in destination are discarded." Running: 'dsync -R -o mail_home=/users/maildir backup ssh -c arcfour src-host "dsync -o mail_home=/users/maildir"' I know it's running as root, but even then ... it shouldn't modify the source in "backup" mode ?? The error message from dsync when failing is: dsync-remote(root): Error: Cached message size larger than expected (5292 > 5289) dsync-remote(root): Error: Maildir filename has wrong S value, renamed the file from /users/maildir/.Sent/cur/1381224782.M959810P3574.mail,S=5292,W=5411:2,S to /users/maildir/.Sent/cur/1381224782.M959810P3574.mail,S=5289:2,S dsync-remote(root): Error: Corrupted index cache file /users/maildir/.Sent/dovecot.index.cache: Broken physical size for mail UID 1040 dsync-remote(root): Error: dsync(dst-host): read(/users/maildir/.Sent/cur/1381224782.M959810P3574.mail,S=5292,W=5411:2,S) failed: Cached message size larger than expected (5292 > 5289) /Peter

[Dovecot] Segfault when deselecting virtual folder 2.2.13+ HG TIP
by Colin Knox 27 May '14

27 May '14

Hello, I'm seeing a segfault in the imap process with the current mercurial tip (including changeset 17382 e99cd21e1f92) when selecting a particular virtual mail folder (but no other virtual mailboxes) and then selecting a different mail folder as in the IMAP transcript below. The same segfaults are triggered with IMAP clients. The situation is worse with the 2.2.13 which segfaults when any virtual mailbox is deselected so the recent patch helps partially. Configuration summary, IMAP session in gbd including backtrace and virtual mailbox spec follow. Any ideas what's causing this?

[Dovecot] Odd ownership of the dovecot-uidlist file
by dclist.hook＠hook.net.nz 27 May '14

27 May '14

Hi, We have just recently switched from Courier to Dovecot for both IMAAP and POP access for our shared hosting platform, and while the issues we have been seeing with Courier have gone away a new one has popped up. Unfortunately googling for an answer is difficult as it falls into the ownership and permissions category which people seem to have all the time. But in those cases it always happens, whereas what we are seeing is a random ownership change on the dovecot-uidlist file. Basically what we see is the user is able to login fine for days and then all of a sudden the file has changed ownership to a user under a different domain, what's worse is the other user has not even logged in during that time. Here's a snippet from a case from a month ago which was escalated to us, there are plenty of other examples but its so random we only know its happened when the customer complains or we happen to watch the logs, the current help desk procedure when the customer calls is to just fix the ownership of the file. -- 8<-- Mar 25 11:18:05 brio dovecot: pop3-login: Login: user=<accounts@DOMAIN1>, method=PLAIN, rip=IP, lip=IP, mpid=21739, TLS, session=<mwQLnGH1ZAB2XalI> Mar 25 11:18:08 brio dovecot: pop3(accounts@DOMAIN1): Disconnected: Logged out top=0 (0 b), retr=4 (274142 b), messages=27 (10797760 b), del=0 Mar 25 11:19:24 brio dovecot: pop3(accounts@DOMAIN1): Error: open(/mnt/spool/keepers/t/DOMAIN1/accounts/Maildir/dovecot-uidlist) failed: Permission denied Mar 25 11:19:24 brio dovecot: pop3(accounts@DOAMIN1): Error: open(/mnt/spool/keepers/t/DOMAIN1/accounts/Maildir/dovecot-uidlist) failed: Permission denied -- 8<-- In this case the ownership of the file was: -rw------- 1 jacqui-30747 DOMAIN2 48839 Mar 25 10:31 dovecot-uidlist when it should be: -rw------- 1 accounts-25105 DOMAIN1 48839 Mar 25 10:32 dovecot-uidlist As you can see both the user and the group have changed to a different user as if that user had recreated the file. Its worth noting that the parent directory does not change: drwx------ 8 accounts-25105 DOMAIN1 4096 Mar 25 10:31 . so this user should not even be able to access this file. It would be great if someone can give us some hints where the problem maybe as this has us stumped. Some more detail if it helps: root@brio:~# dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.2 auth_mechanisms = plain login cram-md5 apop auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@& default_process_limit = 3000 disable_plaintext_auth = no lock_method = dotlock mail_fsync = always mail_location = maildir:~/Maildir:INDEX=/home/indexes/%1d/%n@%d mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = " quota" maildir_stat_dirs = yes mmap_disable = yes 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 = . subscriptions = yes } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } passdb { args = /etc/dovecot/dovecot-sql-cram.conf.ext driver = sql } plugin { quota = maildir:User quota } protocols = " imap pop3" service imap-login { inet_listener imap25 { port = 25143 } } service imap-postlogin { executable = script-login -d /usr/local/bin/postlogin.sh } service imap { executable = imap imap-postlogin } service pop3-login { inet_listener pop325 { port = 25110 } } service pop3 { executable = pop3 imap-postlogin } ssl_cert = </var/www/mailadmin/ssl/cert.pem ssl_crypto_device = dynamic ssl_key = </var/www/mailadmin/ssl/mailx.hosts.net.nz.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } userdb { args = /etc/dovecot/dovecot-sql-cram.conf.ext driver = sql } verbose_proctitle = yes protocol imap { imap_capability = +XHOST_brio imap_logout_format = bytes=%i/%o mail_max_userip_connections = 50 mail_plugins = " quota imap_quota" } protocol pop3 { mail_max_userip_connections = 10 pop3_lock_session = no pop3_logout_format = top=%t (%p b), retr=%r (%b b), messages=%m (%s b), del=%d pop3_save_uidl = yes pop3_uidl_format = %f } root@brio:~# dpkg -l|grep dovecot ii dovecot-core 1:2.1.7-7 amd64 secure mail server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-imapd 1:2.1.7-7 amd64 secure IMAP server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-mysql 1:2.1.7-7 amd64 MySQL support for Dovecot ii dovecot-pop3d 1:2.1.7-7 amd64 secure POP3 server that supports mbox, maildir, dbox and mdbox mailboxes Mailbox storage is done over various NFS stores, however each user has a specific NFS store Connections are load balanced using LVS and keepalived over approx 10 real servers, persistant connections are setup so that a single user should only hit a single dovecot server (this is different from our courier setup due to the known NFS limitations with dovecot) We also have IMAP indexes stored on the dovecot servers ext3 file system itself rather than NFS. Each server is setup and maintained by puppet, and any one of the servers may see the issue. All servers are x86 with at least 2Gb of RAM User information comes from a MySQL database, and testing the SQL statements only ever return the correct record. Exim is writing to the Maildir with the correct permissions, and after fixing the ownership of the file dovecot can read and change the mailboxes. We do have a postlogin.sh script which runs after authentication to convert the old courier files over to the dovecot ones, this only happens however when the process has not run before (it appears dovecot deletes the files and recreates them, so we use a state file). Adding debugging to the script shows its running as the correct user at the last successful login. It does not run at all after the ownership has changed. There are some users who this is happening regularly, and other users who it has happened to only once. It is also not just limited to POP3, although this is where we commonly see it as dovecot accepts the IMAP connection if the ownership on a sub folders uidlist is different. If you need any further detail, I can provide it. Debugging could be much more difficult because of how random it is, while it can happen daily there have been periods of up to one week before its seen. Any help in finding this would be greatly appreciated, Cheers, Bruce

[Dovecot] Incorrect IMAP search results when FTS/Squat indexes are present with 2.1.7
by Robert L Mathews 27 May '14

27 May '14

We recently upgraded from Dovecot 1.2.15 (on Debian squeeze) to Dovecot 2.1.7 (on Debian wheezy/stable). For now, we continue to use FTS with Squat indexes. We'd like to eventually switch to Lucene but it's not yet supported in Debian stable. Since upgrading to 2.1.7, we've seen some problems with IMAP search results when an FTS Squat index is present (i.e., when the "dovecot.index.search" and "dovecot.index.search.uids" files are present). If it's present, even header searches sometimes give incorrect results (such as searches on FROM or SUBJECT headers). I'm wondering if this is a known issue with 2.1.7 and whether upgrading to a later version of Dovecot with Squat is likely to fix this (due to, say, <http://www.dovecot.org/list/dovecot-cvs/2012-June/020881.html>), or if Squat in all versions is a lost cause and I need to switch to Lucene. I can demonstrate the problem by showing the results of three searches on my mailbox. First, here are the correct results for header FTS searches when no "dovecot.index.search[.uids]" file is present: ---- .

[Dovecot] LDAP: allow pop3, restrict imap
by Andreas Schulze 26 May '14

26 May '14

Hello, I have all userdata in a ldapserver. Every user has the right to use pop3. There is no explicit attribute allowing that. It's simply possible. Now I like to add imap. For a starting period I like to restrict, who may use imap. http://wiki2.dovecot.org/Authentication/RestrictAccess mention a solution where I could modify ldap pass_filter. But that require an attribute "service=pop3" to be present in the ldap servers. In my case I have to add it for every existing user :-/ No way... Are there other options? Thanks, Andreas

[Dovecot] socket /var/spool/postfix/private/auth not created
by lister171254 26 May '14

26 May '14

I'm on Ubuntu 13.10 and followed these instructions http://wiki2.dovecot.org/HowTo/PostfixAndDovecotSASL to configure Dovecot for Postfix. No matter what I try, the listener is not created. <http://dovecot.2317879.n4.nabble.com/file/n48182/32.png> dovecot -n does not show the listener (I guess that's why its not created) This is the extract from the /etc/dovecot/conf.d/10-master.conf --------------- service auth { # auth_socket_path points to this userdb socket by default. It's typically # used by dovecot-lda, doveadm, possibly imap process, etc. Users that have # full permissions to this socket are able to get a list of all usernames and # get the results of everyone's userdb lookups. # # The default 0666 mode allows anyone to connect to the socket, but the # userdb lookups will succeed only if the userdb returns an "uid" field that # matches the caller process's UID. Also if caller's uid or gid matches the # socket's uid or gid the lookup succeeds. Anything else causes a failure. # # To give the caller full permissions to lookup all users, set the mode to # something else than 0666 and Dovecot lets the kernel enforce the # permissions (e.g. 0777 allows everyone full permissions). unix_listener auth-userdb { #mode = 0666 #user = #group = } # Postfix smtp-auth unix_listener /var/spool/postfix/private/auth { mode = 0600 user = postfix group = postfix } # Auth process is run as this user. #user = $default_internal_user } ---------------- Postfix is not involved in this right now as I expect the socket to be created when I restart dovecot. Can't find any meaningfull errors in the logs either. I hope I'm missing something obvious Thanks, Leo -- View this message in context: http://dovecot.2317879.n4.nabble.com/socket-var-spool-postfix-private-auth-… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Copies of outgoing emails in the Sent folder
by Dmitry Podkovyrkin 26 May '14

26 May '14

Hi! My mail server works in tandem: Dovecot (IMAP) + Postfix. How can I configure in Gmail: Outgoing email copied to the Sent folder using postfix without mail client? This question is for the mailing list for Postfix? Mail client itself copies outgoing messages in the folder Sent, but the messages are large, and the server is far away. And to transmit email twice for sending and copying is not effective. Sorry for my English ). -- Regards Dmitry Podkovyrkin mobile: +7 922 20 56 756 email: dmirty(a)rutelecom.company skype: dmitryrw

[Dovecot] Multilayer mail handling
by Jimmy Thrasibule 26 May '14

26 May '14

Hi, I'm wondering what is the correct architecture and configuration to setup a multilayer mail handling? What I have in mind is something more like what we can found in Web platform architectures. 1. First layer does first checks: user authentication and SSL offloading. If all checks are OK request is proxied to layer 2. 2. Second layer, will actually handle the IMAP/POP3 connection proxied by layer 1, no major checks should be done as already made by layer 1. 3. Finally, layer 3 to do some virus checks on the emails and maybe some other things I can't think about. Do you have some pointers on how to set up such a mail stack where each layer can be on multiple other hosts? Best regards, Jimmy

[Dovecot] Index cache errors worse with 2.2.x
by Alexander 'Leo' Bergolth 25 May '14

25 May '14

Hi! I am getting "Cached message size smaller than expected" errors since dovecot-2.1.x. Until now, I thought that those errors don't do any harm, I assumed that the cache will just be rebuilt after the error had been detected. However, since dovecot 2.2.x (I tried 2.2.7 and 2.2.10), the errors sometimes seem to actually cause mail access to fail. With dovecot-2.1.1, only the first two messages were logged, since using 2.2.7 and 2.2.10, the "read ... failed: Invalid argument" sometimes appear: -------------------- 8< -------------------- May 7 17:03:52 samba dovecot: imap(xyz): Error: Cached message size smaller than expected (2246 < 2247) May 7 17:03:52 samba dovecot: imap(xyz): Error: Corrupted index cache file /home/xyz/mail/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 11277 May 7 17:03:52 samba dovecot: imap(xyz): Error: read(/var/mail/xyz) failed: Invalid argument May 7 17:03:52 samba dovecot: imap(xyz): Error: read(/var/mail/xyz) failed: Invalid argument (uid=11277) -------------------- 8< -------------------- I am using dovecot on RHEL6 with mbox mailboxes. Message size differences are always 1 byte. Any hints would be appreciated! Cheers, --leo P.S.: Those errors occur some times a day and affect different users..
