New created users can not log in
by Ferdinand Gruber 17 Sep '15

17 Sep '15

Hi, I am using dovecot 2.2 for some time. All users on the system can log in using Horde Webmail. But now, after creating a new user on the server with <useradd -m username> this new user is not able to log in. Of course I have set a password for the new user. In the log file I can see: Sep 16 23:04:05 servername auth: gkr-pam: error looking up user information Sep 16 23:04:07 servername HORDE: [imp] [login] Authentication failed. [pid 1584 on line 730 of "/srv/www/htdocs/horde/imp/lib/Imap.php"] Sep 16 23:04:07 servername HORDE: [imp] FAILED LOGIN for calendar (93.82.157.132) to {imap://localhost/} [pid 1584 on line 157 of "/srv/www/htdocs/horde/imp/lib/Auth.php"] Sep 16 23:04:07 servername HORDE: [horde] FAILED LOGIN for calendar to horde (93.82.157.132) [pid 1584 on line 199 of "/srv/www/htdocs/horde/login.php"] Please give me a hint. -- Ferdinand

How to "Windows Authenticate"
by Mark Foley 17 Sep '15

17 Sep '15

I've been using Dovecot 2.2.15 as the IMAP server for Outlook (2010/2013) on Windows workstations for over 6 months with no problems. Dovecot is hosted on the office Samba4 AC/DC server. I have been using auth_mechanisms plain login, and passdb driver = shadow. What I'd like to do now is use the "Windows Authenticated" login so I don't have to have separate passwords for users logging into the Windows AD workstations and their Outlook clients. If anyone has actually done this I'd appreciate some tips. My various attempts have not been successful. Here is my current config: $ doveconf -n # 2.2.15: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.10.17 x86_64 Slackware 14.1 auth_debug_passwords = yes auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no info_log_path = /var/log/dovecot_info mail_location = maildir:~/Maildir passdb { driver = shadow } protocols = imap ssl_cert = </etc/ssl/certs/OHPRS/GoDaddy/Apache/c5fe0cc8242d6030.crt ssl_key = </etc/ssl/certs/OHPRS/GoDaddy/mail.ohprs.org.key userdb { driver = passwd } verbose_ssl = yes Thanks, Mark Foley

FreeBSD 10 & default_vsz_limit causing reboots?
by Rick Romero 15 Sep '15

15 Sep '15

Ok, So this is really more of an observation than anything else. I had a FreeBSD 10.1 server that was running great. Some SSL issue came up, or I upgrade Dovecot in ports - something occurred and the machine started rebooting randomly. It would run for 2 weeks, then reboot. It might run for 5 days and then reboot. So I started doing more FreeBSD upgrades, thinking it was a kernel issue. The reboots only increased. This weekend I started thinking I might actually be having hardware issues. But, since I don't have easy physical access to the box and it's REALLY under loaded, I figured what the hell and upraded to 10.2 on Sunday. I think it rebooted 4 times after that on Sunday, and then another 2 times Monday morning. Its worth noting that while I have crash dumps enabled, they don't seem to be occurring. So hardware is still a possibility. After the 2nd Monday morning reboot, I started to wonder if there was some sort of process issue. Besides the OS upgrades - I had been monitoring the Dovecot logs for when the process limits are reached, and increasing them. It's a 'big' box, and load is typically between .30 and .50. CPUs aren't overtaxed, and most of the memory is dedicated to ZFS. The reboots are so short, I've only received one 'down' alert due to them. So it's a conerning issue, but not really impacting production. On a whim I changed my default_vsz_limit (as I had been increasing every other limit but that) from 384M to 512M. The system hasn't rebooted in 24hours. Now that could be a coincidence, but I thought I'd at least put it out there. If you see anything weird in my dovecot config, let me know - My config was originally vpopmail, but over time I've migrated to SQL-only. root@romulus:/usr/local/etc/dovecot # dovecot -n # 2.2.18: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 10.2-RELEASE amd64 auth_master_user_separator = * auth_mechanisms = plain login auth_username_translation = %@ auth_verbose = yes default_login_user = dovecot default_vsz_limit = 512 M disable_plaintext_auth = no first_valid_gid = 89 first_valid_uid = 89 last_valid_gid = 89 last_valid_uid = 89 log_path = /dev/stderr login_greeting = Ready. login_trusted_networks = 172.16.100.0/24 mail_fsync = never mail_plugins = " quota zlib stats" mail_privileged_group = mail namespace compat { alias_for = hidden = yes inbox = no list = no location = prefix = INBOX. separator = . } namespace inbox { inbox = yes location = prefix = separator = . } passdb { args = /usr/local/etc/dovecot/dovecot-master-sql.conf driver = sql master = yes pass = yes } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf driver = sql } plugin { quota = maildir quota_rule = Trash:storage=+10%% stats_refresh = 30 secs stats_track_cmds = yes } protocols = imap pop3 service anvil { client_limit = 3175 } service auth { client_limit = 3684 unix_listener auth-master { mode = 0600 } } service imap-login { process_limit = 1536 process_min_avail = 25 service_count = 1 } service imap-postlogin { executable = script-login rawlog /usr/local/etc/dovecot/lastauth-imap.sh user = vpopmail } service imap { executable = /usr/local/libexec/dovecot/imap imap-postlogin process_limit = 1536 } service pop-postlogin { executable = script-login /usr/local/etc/dovecot/lastauth-pop.sh user = vpopmail } service pop3-login { process_limit = 1536 process_min_avail = 15 service_count = 1 } service pop3 { executable = /usr/local/libexec/dovecot/pop3 pop-postlogin } service stats { fifo_listener stats-mail { mode = 0600 user = vpopmail } } shutdown_clients = no ssl_cert = </etc/ssl/mail.pem ssl_key = </etc/ssl/mail.key ssl_key_password = na userdb { driver = prefetch } verbose_proctitle = yes protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep mail_max_userip_connections = 100 mail_plugins = " quota zlib stats imap_zlib quota imap_quota" } protocol pop3 { mail_max_userip_connections = 100 mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv }

Dovecot does not accept new connection with error "imap-login: Error: read(anvil) failed: EOF"
by Julien Fastré 14 Sep '15

14 Sep '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, First of all, thank you for the work the contributors are doing with Dovecot ! Dovecot is doing a great job ! I am encountering a problem with a configuration and, despite my search on the web, I do not find any solution for this problem. Dovecot seems to stop accepting new connection. The users : - - can not save sent messages to "Sent" folder (using Thunderbird) ; - - can not connect or retrieve message from webmail (using sogo or roundcube) In the log, I see this error : > Jun 30 13:54:53 mail dovecot: imap-login: Error: read(anvil) > failed: EOF Jun 30 13:54:53 mail dovecot: message repeated 2 times: > [ imap-login: Error: read(anvil) failed: EOF] (the message may be repeated more than 2 times) It happens... sometimes. Manually restarting the dovecot service make the software working again. By searching on the web, I regularly see this statement in logs : > dovecot: auth: Error: read(anvil-auth-penalty) failed: EOF like here : http://www.dovecot.org/list/dovecot/2010-November/054694.htm l But it doesn't seem to be the same problem as mine (anvil / anvil-auth-penalty). The problem happens during peak load. Sometimes it happens twice a week, sometimes it may spent two month without any problem (during holidays, I did not had any problem). My configuration : > # doveconf -n # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux > 3.13.0-49-generic x86_64 Ubuntu 14.04.3 LTS login_trusted_networks > = 10.0.3.0/24 mail_location = mbox:~/mail:INBOX=/var/mail/%u > mail_plugins = quota acl 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 namespace { list = children location > = maildir:/var/mail-data/vhosts/%%u:INDEX=~/shared/%%u prefix = > shared/%%u/ separator = / subscriptions = no type = shared } > 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 > = separator = / type = private } passdb { driver = pam } passdb { > args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { > acl = vfile acl_shared_dict = > file:/var/mail-data/acl_db/shared-mailboxes quota = maildir:User > quota quota_grace = 10%% quota_rule = *:storage=2G quota_rule2 = > Trash:storage=+100M sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } > postmaster_address = julienfastre(a)cvfe.be protocols = " imap lmtp > sieve" service auth { unix_listener > /var/spool/postfix/private/dovecot-auth { group = postfix mode = > 0660 user = postfix } } service lmtp { unix_listener > /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = > 0600 user = postfix } } ssl_ca = </etc/dovecot/certificates/ca.pem > ssl_cert = </etc/dovecot/certificates/mail.cert.pem ssl_key = > </etc/dovecot/certificates/mail.key.nopass.pem userdb { driver = > passwd } userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver > = ldap } protocol lmtp { mail_plugins = quota acl sieve } protocol > imap { mail_max_userip_connections = 30 mail_plugins = quota acl > imap_quota imap_acl } As somes answer about anvil-auth-penalty may suggest it is linked with proc capabilities, this is the limitation of the /proc > root@mail:/home/ubuntu# ps -aux | grep anvil postfix 4568 0.0 > 0.0 27404 1596 ?

Need help on checkpassword userdb/passdb
by Mark Foley 13 Sep '15

13 Sep '15

I'm experimenting with checkpassword as an auth method for usedb and passdb (http://wiki2.dovecot.org/AuthDatabase/CheckPassword) I've set up the userdb and passdb *exactly* as the wiki suggests as the "standard way": passdb { driver = checkpassword args = /user/util/bin/checkpassword } userdb { driver = prefetch } I've created a checkpassword program that does receive the correct user and password from dovecot. And I am successfully authenticating with ntlm_auth and exiting with status 0. My debug output: AUTHORIZED: (null) USER: (null) userdb_uid: (null) userdb_gid: (null) arg1=/usr/local/libexec/dovecot/checkpassword-reply CMD: /usr/bin/ntlm_auth --username="mark" --password='mypass' ntlm_auth status: 0 Now, the wiki says 2 things that have me stumped: 1. It says that, "Dovecot calls the script with AUTHORIZED=1 environment set when performing a userdb lookup. The script must acknowledge this by changing the environment to AUTHORIZED=2, otherwise the lookup fails." As you can see from my program log, "AUTHORIZED" is not set. Why? Nor are any of the other environment variables mentioned in the wiki. I've listed all the environment variables that *are* passed to the program at the bottom of this message. 2. The wiki says, "Your program received a path to checkpassword-reply binary as the first parameter. Execute it." I did so as a fork() and then execve("/usr/local/libexec/dovecot/checkpassword-reply") How do I know it worked ... or failed? What am I doing wrong?

Dovecot CalDAV server
by Timo Sirainen 11 Sep '15

11 Sep '15

I've been once in a while over the years thinking about implementing CalDAV (and CardDAV) to Dovecot. It might be time to start that soon. Does anyone have any suggestions? So far my main goals would be: - scalable, of course - configurable storage (object storage, regular fs, maybe some key-value dbs, maybe storing as emails) - efficient indexes (potentially using key-value dbs? or maybe just local files. not sure yet what kind of indexing is needed) - have it work with dsync (= replication & migration) Some things I wonder about: - Maybe there is already some code out there that could be used to implement it faster? - Maybe even use something else besides C to implement it.. Then again that makes integration to Dovecot more difficult. - Is anybody interested in helping to develop this? :) I think I still have too much other work that I won't spend a lot of time coding it.. One thing that makes this easier is that Open-Xchange has already implemented a CalDAV server, so they can help to avoid the biggest design mistakes. (There are a couple of reasons why they'd want to replace that.)

My dovecot works fine against Active Directory 2003, but not against AD2008
by Fran 10 Sep '15

10 Sep '15

Hello, my dovecot installation has been working fine against AD till we upgrade from AD 2003 to AD 2008. As http://wiki2.dovecot.org/AuthDatabase/LDAP said, now I'm not able to connect AD through 389 port. The port 3268 works fine though. (...) Sep 7 19:02:05 <dovecotServer> dovecot: imap-login: Error: master(imap): Auth request timed out (received 0/12 bytes) Sep 7 19:02:05 <dovecotServer> dovecot: imap-login: Internal login failure (pid=4846 id=1) (internal failure, 1 successful auths): user=<<username>>, method=PLAIN, rip=<clientLAN_IP>, lip=<dovecotServer_IP>, TLS, session=<T+grMCsfqgAKHyZV> (...) Sep 7 19:02:06 <dovecotServer> dovecot: auth: Error: ldap(<username>,<clientLAN_IP>,<ZjyONSsf6QAKHyZV>): Connection appears to be hanging, reconnecting Sep 7 19:02:06 <dovecotServer> dovecot: auth: Error: ldap(<username>,<clientLAN_IP>,<T+grMCsfqgAKHyZV>): LDAP search returned multiple entries (...) Is there a technical reason for this problem? Does it exist any workaround? The use of Global Catalog (port 3268) is not a solution for me, since it misses many attributes. (ex. I use the field "initials" to set the quota and this field is not available through port 3268). I also noticed that, now, it uses any DC available in the domain, it doesn't care what I configured in "hosts = " parameter. This is using "hosts = dc03.domain:389": ----------------------------------------------- [root@<dovecotServer> ~]# netstat -anp | grep dovecot | grep auth tcp 22 0 <dovecotServer_IP>:55217 <dc03.domain_IP>:389 ESTABLISHED 4872/dovecot/auth tcp 22 0 <dovecotServer_IP>:57645 <dc06.domain_IP>:389 ESTABLISHED 4872/dovecot/auth tcp 0 0 <dovecotServer_IP>:55216 <dc03.domain_IP>:389 ESTABLISHED 4872/dovecot/auth It looks like it does a look up for other domains controller (I don't know how nor why) and it connect aleatory to any DC in my domain (in this case dc06.domain, but it changes any time), additionally to the configured one (dc03.domain). This is using "hosts = dc03.domain:3268": ------------------------------------------------ [root@<dovecotServer> ~]# netstat -anp | grep dovecot | grep auth tcp 0 0 <dovecotServer_IP>:58485

Convert from Maildir to Mdbox
by J. Echter 09 Sep '15

09 Sep '15

Hi, i'd like to convert from maildir to mdbox. what would be the best way to do this? i have read the dsync part of the dovecot wiki but i don't get what i have to use for my setup. my dovecot.conf (the snippets i think would matter): mail_gid = 5000 mail_home = /DATEN/vmail/%d/%n mail_location = maildir:/DATEN/vmail/%d/%n/mail/ mail_plugins = " zlib" mail_uid = 5000 Thanks for your input.

[Dovecot] dsync replication errors
by Oli Schacher 09 Sep '15

09 Sep '15

Hi I'm trying to build a cluster of two servers with dsync replication (based on http://wiki2.dovecot.org/Replication) My test setup works fine for very simple tests, I can log in to both servers, copy a message to one of the servers and it successfully apperars in the other account. But, if I try to copy a large amount of messages at once to one of the accounts, my maillogs get flodded with errors(see below) and the mailboxes seem to get out of sync and messages are duplicated over and over again (I originally copied 100 messages and ended up with thousands in both mailboxes until I killed dovecot) I'd appreciate if someone could have a look at my config and tell me what I did wrong. dovecot.conf of both servers, they are identical except for the target ip in mail_replica: dovecot -n # 2.2.beta1 (070ca24e5846+): /etc/dovecot/dovecot.conf # OS: Linux

sieve_extprograms - double linebreaks at filtering
by Hajo Locke 09 Sep '15

09 Sep '15

Hello List, i have a problem when using sieve-plugin sieve_extprograms. I use dovecot 2.2.18 and bundled pigeonhole 0.4.6 (Ubuntu 14.04.3 LTS) i have enabled sieve_extprograms and vnd.dovecot.filter to send mail to user-defined script and get changed content back. My script previously was used with procmail and is working fine. Using same script with vnd.dovecot.filter leads to odd behavior. I already found out the problem itself: By sending Mailcontent to filter-programm it seems that sieve/sieve_extprograms is adding additional linebreaks to every line of complete mail. Please see this image to clarify: http://r31i.imgup.net/header8d56.jpg?l=de Every lineending got additional windows-lineendings, which leads to problems with processing scripts. Piping mails by procmail to same script is working without problems, because this mails are recieved "clean" without the "^M". this is part of dovecot.conf: plugin { sieve = ~/.dovecot.sieve sieve_plugins = sieve_extprograms sieve_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter +vnd.dovecot.execute sieve_pipe_bin_dir = /usr/local/bin/ sieve_filter_bin_dir = /usr/local/bin/ } this is part of userscript ~/.dovecot.sieve: require ["fileinto", "vacation", "variables", "envelope", "imap4flags", "vnd.dovecot.filter", "subaddress"]; if address "to" "test2(a)example.com" { filter "my-script"; } my-script currently just recieves and saves raw-data, so i could find difference between sieve and procmail mails. What to do here? Is this a kind of bug of sieve/sieve_extprograms or i have to use additional parameters? Thanks, Hajo

Problems setting up SIS (duplicate files with same hash)
by Joe Beaubien 09 Sep '15

09 Sep '15

Hi everyone, I am currently trying to setup our next dovecot server (2.2.18) with SIS enabled, but I have enconutered 1 problem and 1 question: *1) Same attachment, different filenames* I have a feeling a misconfigured something (or forgot to do something) because SIS almost works, but not quite since 3 identical attachment take 3x the space (see end of email for my SIS config). For 3 the emails I sent with the same attachment, I got 3 seperate files with the same hash name but a different string following the dash: -rw------- 1 info info 2.6M Sep 5 11:14 e35083e3280a21c6aaabbae8cb23d54493f514a5-6a22711a7b05eb5509480000045c9bf4 -rw------- 1 info info 2.6M Sep 5 11:16 e35083e3280a21c6aaabbae8cb23d54493f514a5-6c22711a7b05eb5509480000045c9bf4 -rw------- 2 info info 2.6M Sep 5 11:18 e35083e3280a21c6aaabbae8cb23d54493f514a5-6e22711a7b05eb5509480000045c9bf4 drwx------ 2 info info 4.0K Sep 5 11:18 hashes For the record, the "hashes" subfolder has only 1 hash (e35083e3280a21c6aaabbae8cb23d54493f514a5) which perfectly matches the first part of the 3 filenames. *2) Saving attachments under a generic name or more flexible permissions?* It seems that dovecot saves the attachment with the username and group of the user who has received the email. Is it possible to have dovecot save the attachments as a generic user (like dovecot or dovenull) so that all my different users can share the same pool of attachments? Alternatively, is it possible to have dovecot save the attachment under more flexible permissions so that they can be shared between users? This would allow us to save alot of disk space. *Here is the SIS config I am using:* mail_attachment_dir = /data/emails/attachments #mail_attachment_min_size = 128k #mail_attachment_fs = sis posix #mail_attachment_hash = %{sha1} Any help would be very much appreciated. Thank you, Joe B

Dovecot and IPA
by Kanwar Ranbir Sandhu 08 Sep '15

08 Sep '15

Hello, I'm trying to get Dovecot to use GSSAPI for authentication. I have an IPA server on CentOS 7 with a bunch of my servers attached to the IPA domain, including the server running Dovecot. I've followed official documentation from Red Hat and read numerous wiki articles on how to configure Dovecot to get it to use GSSAPI correctly. I don't think I've done anything incorrectly, but it refuses to work. This is the error I'm seeing: mailman02 dovecot: imap-login: Disconnected (tried to use unsupported auth mechanism): user=<>, method=PLAIN, rip=1.1.1.1, lip=2.2.2.2, TLS, session=<QhWSqxofyAAKyAkM> I don't understand why no username is being passed. My mail client is Evolution 3.10.4. FYI, Dovecot does work fine using a user/password file. I'm just trying to switch it over to GSSAPI so that I can manage passwords from one system. Any help would be appreciated. Regards, Ranbir -- Kanwar R.S. Sandhu

Multiple vacation
by Michele Locati 08 Sep '15

08 Sep '15

Hi all I'm using Dovecot 2.2.9 and I'm having problems configuring multiple vacation actions. The problem is that I'd like to have two different senders and two different messages, selecting the correct case by the recipient email address. I mean, if someone writes me to my email address "to-address1(a)example.com" I'd like to answer from "from-address1(a)example.com" with the message "TEST 1". If someone writes me to my email address "to-address2(a)example.com" I'd like to answer from "from-address2(a)example.com" with the message "TEST 2". Here's my script: require ["fileinto","vacation"]; vacation :addresses ["to-address1(a)example.com"] :from " from-address1(a)example.com" text: TEST 1 . ; } vacation :addresses ["to-address2(a)example.com"] :from " from-address2(a)example.com" text: TEST 2 . ; But the vacation filter doesn't work, and I see this message in the log file: main script: line X: error: duplicate vacation action not allowed (previously triggered one was here: main script: line Y). Is there a way to allow multiple vacation actions? Thank you Michele

Public folder subscriptions with Outlook
by Paul Tansom 08 Sep '15

08 Sep '15

This is more an Outlook issue than Dovecot, but given that it is connected to Dovecot I figured there would be a good pool of knowledge here that increases the likelihood that somebody knows the answer :) I have a Dovecot server setup with a public folder and keep getting complaints that Outlook users don't see new folders created by other people. In Thunderbird it is simply a case of unchecking the box to only show subscribed folders, but I can't find a way to do this in Outlook. The only thing I can think of is putting a script on the server to check for new folders and update each users subcriptions file, but I'm not completely happy with that solution! Any suggestions welcome. -- Paul Tansom | Aptanet Ltd. | https://www.aptanet.com/ | 023 9238 0001 Vice Chair, FSB Portsmouth & SE Hampshire Branch | http://www.fsb.org.uk/ ============================================================================= Registered in England | Company No: 4905028 | Registered Office: Ralls House, Parklands Business Park, Forrest Road, Denmead, Waterlooville, Hants, PO7 6XP

Different behavior of ACLs in MUA and doveadm
by Thomas Leuxner 08 Sep '15

08 Sep '15

I have noticed a difference in the behavior of ACLs. When used in a MUA the following global ACL works fine and has the desired effect - new mailboxes can be created by a user being part of the 'PublicMailboxAdmins' group: [ global-acl: ] INBOX owner lrwstiekxap Public/* group=PublicMailboxAdmins lrwsipk Public/* anyone lr Public/* authenticated lrws Creating the same mailbox via doveadm however fails with a permission problem: doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=public, prefix=Public/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=no location=mdbox:/var/vmail/public:INDEXPVT=~/mdbox/public doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/public, index=, indexpvt=/var/vmail/domains/leuxner.net/tlx/mdbox/public, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 0 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=private, prefix=Virtual/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=virtual:~/mdbox/virtual doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/domains/leuxner.net/tlx/mdbox/virtual, index=, indexpvt=, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 1 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/dovecot-acl not found doveadm(tlx(a)leuxner.net): Error: Can't create mailbox Public/Archive/Newsletters/heise-security/2014: Permission denied Interestingly, doveadm succeeds when dovecot-acl is present in the namespace root - which of course is not desirable in the light of the global ACL: [ dovecot-acl: ] group=PublicMailboxAdmins lrwsipk doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=public, prefix=Public/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=no location=mdbox:/var/vmail/public:INDEXPVT=~/mdbox/public doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/public, index=, indexpvt=/var/vmail/domains/leuxner.net/tlx/mdbox/public, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 0 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=private, prefix=Virtual/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=virtual:~/mdbox/virtual doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/domains/leuxner.net/tlx/mdbox/virtual, index=, indexpvt=, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 1 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: acl vfile: reading file /var/vmail/public/mailboxes/dovecot-acl doveadm(tlx(a)leuxner.net): Debug: Namespace Public/: /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014 doesn't exist yet, using default permissions doveadm(tlx(a)leuxner.net): Debug: Namespace Public/: Using permissions from /var/vmail/public: mode=0700 gid=default doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/dbox-Mails/dovecot-acl not found doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014/dbox-Mails/dovecot-acl not found doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014/dbox-Mails/dovecot-acl not found doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014/dbox-Mails/dovecot-acl not found # 2.2.15 (6078354e6238): /etc/dovecot/dovecot.conf I know there have been some changes in Mercurial as to how global ACLs are interpreted. Is doveadm probably behind on them? Regards Thomas

Fetch command response questions
by Vlad Pop 08 Sep '15

08 Sep '15

Hello, I have the following issue: When using command FETCH 2 (BODY.PEEK[HEADER] UID INTERNALDATE FLAGS BODYSTRUCTURE) on 2 different emails, we get 2 different response structure. First response structure contains the BODYSTRUCTURE in a single line, while in the second response, the BODYSTRUCTURE is divided into multiple lines with "{61}" character at the end of each line. The difference between those 2 emails is the name of some attachments. The attachment is an .eml file named "Re: [SR-Users] Keep-Alive in dialog "freeing a free fragment"" Is this a sort of bug or is it correct to receive the BODYSTRUCTURE on multiple lines? Vlad Pop

segfault when using zlib module with glibc 2.22
by Florian Pritz 08 Sep '15

08 Sep '15

Hi, I'm seeing the following segfault when I run `doveadm search mailbox inbox` with the zlib module enabled with dovecot 2.18 and glibc 2.22 on Arch Linux. It does not happen with glibc 2.21. I've noticed that when I remove "zlib" from the mail_plugins line at the beginning of the config file the segfault goes away. I've also tested hg tip and the problem does not appear to be fixed yet. The segfault also happens with other commands like `doveadm purge`. Do you need any more information to reproduce and fix this?

File permissions: system groups for do not work for group/shared mailboxes
by Jens Kirchner 08 Sep '15

08 Sep '15

Hello! I am struggling to set up a group mailbox for users of a certain system group. I want to grant access to the mailbox on a filesystem mode by using the system groups. The problem, the set up works fine and when I use setfacl and grant permissions too each user manually, it works fine. However, I want to use a system user's group membership in order to grant access to these mailboxes insted of manually granting for each user. dovecot version: 2.2.9 This is the config part: namespace { location = maildir:/data/mail/public:LAYOUT=fs prefix = GROUP-MAILBOXES/ separator = / subscriptions = no type = public } ... passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } ... userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } filesystem permissions (getfacl): # file: GroupboxA/ # owner: root # group: root user::rwx user:user1:rwx group::rwx mask::rwx other::--- default:user::rwx default:user:user1:rwx default:group::rwx default:mask::rwx default:other::--- # file: GroupboxB/ # owner: root # group: root user::rwx group::rwx group:group1:rwx mask::rwx other::--- default:user::rwx default:group::rwx default:group:group1:rwx default:mask::rwx default:other::--- user1 is in roup1 When setting username-based permissions (GroupboxA), the mailbox is usable and subsribable; when setting groupname-based permissions (GroupboxB) it is not subscribable/usable. Thanks for your help in advance and best regards, Jens

bug in acl_defaults_from_inbox option
by Marco Giunta 08 Sep '15

08 Sep '15

Hi at all, there is a bug in in acl_defaults_from_inbox option: if you define it with ANY value ('yes', 'no', 'whatyouwant', 'xxx') it acts like the value is ALWAYS 'yes', and Dovecot enable it; the only way to disable it, is comment it or delete from configuration file. With 'acl_defaults_from_inbox = no', or 'acl_defaults_from_inbox = whatyouwant', all my folders get ACLs from INBOX; in my case I want to only share INBOX, but also all other folders were shared. When you comment 'acl_defaults_from_inbox', Dovecot works like expected.

Patch for "doveadm -f table" nit (was Re: Dovecot current number of connections being used.)
by Joseph Tam 08 Sep '15

08 Sep '15

> doveadm who -1 2>/dev/null | wc -l You have to redirect stderr to /dev/null because that's where the first header line is written to. The default format style (table) is inconsistent with the other formats (flow,pager,tab) that write headers and data to stdout. The following patch will pick this nit. This patch will require modifications to scripts that rely on doveadm writing headers to stderr.

Dear, use our static analysis tools, I find some bugs (Null deference pointer) for dovecot-2.2.18. Null deference pointer bugs often make program crashes, Please confim them, Thanks! 1. dovecot-2.2.18/src/config/config-request.c 332 'setting_export_section_name(ctx->prefix, def, children[i], i);', pointer 'children' in line 202 assigned NULL and if branch 'case SET_DEFLIST_UNIQUE' not execute, so pointer 'children' is always NULL. It load to a bug of null deference pointer In line 332.

RFC 5465 (NOTIFY) violation: missing HIGHESTMODSEQ in initial STATUS responses
by Guilhem Moulin 08 Sep '15

08 Sep '15

Quoting RFC 5465 (NOTIFY): “If the NOTIFY command enables MessageNew, MessageExpunge, AnnotationChange, or FlagChange notifications for a mailbox other than the currently selected mailbox, and the client has specified the STATUS indicator parameter, then the server MUST send a STATUS response for that mailbox before NOTIFY's tagged OK. […] If either AnnotationChange or FlagChange are included and the server also supports the CONDSTORE [RFC4551] and/or QRESYNC [RFC5162] extensions, the STATUS response MUST contain UIDVALIDITY and HIGHESTMODSEQ.” — https://tools.ietf.org/html/rfc5465#section-3.1 While unsolicited STATUS responses include HIGHESTMODSEQ indeed, the initial STATUS responses (caused by the presence of the STATUS indicator) do not: ~$ /usr/lib/dovecot/imap * PREAUTH [CAPABILITY IMAP4rev1 … CONDSTORE QRESYNC … NOTIFY SPECIAL-USE] Logged in as guilhem a ENABLE QRESYNC * ENABLED QRESYNC a OK Enabled (0.000 secs). b NOTIFY SET STATUS (SUBSCRIBED (MessageNew MessageExpunge FlagChange)) * STATUS INBOX (MESSAGES 9069 UIDNEXT 109398 UIDVALIDITY 1312585007 UNSEEN 0) […] b OK NOTIFY completed (0.008 secs). [time passes… a new message is delivered to INBOX] * STATUS INBOX (MESSAGES 9070 UIDNEXT 109399 UNSEEN 1 HIGHESTMODSEQ 22216) This defeats the purpose of the STATUS indicator for disconnected clients since they have to issue separate STATUS commands (or a LIST command if LIST-{EXTENDED,STATUS} have been advertized) to find out which mailboxes have got a new HIGHESTMODSEQ. Cheers, -- Guilhem.

NOTIFY regression: 2.18 no longer notifies of events in INBOX
by Guilhem Moulin 08 Sep '15

08 Sep '15

Here is an example with APPEND $ /usr/lib/dovecot/imap S1: * PREAUTH [CAPABILITY IMAP4rev1 … MOVE NOTIFY SPECIAL-USE] Logged in as guilhem C1: a1 NOTIFY SET (INBOXES (MessageNew MessageExpunge FlagChange)) S1: a1 OK NOTIFY completed (0.000 secs) $ /usr/lib/dovecot/imap S2: * PREAUTH [CAPABILITY IMAP4rev1 … MOVE NOTIFY SPECIAL-USE] Logged in as guilhem C2: a2 APPEND INBOX {1+} C2: x S2: a2 OK [APPENDUID 1384472528 26085] Append completed (0.229 secs). With 2.13 from Debian Jessie, S1 sends a notification for the new message in INBOX, as expected: S1: * STATUS INBOX (MESSAGES 4333 UIDNEXT 26086 UNSEEN 1) However it doesn't with 2.18 from Debian Sid, as if ‘INBOX’ was excluded from the mailbox filter ‘INBOXES’. It does send a notification for ‘virtual/unseen’ instead (as expected), but nothing for ‘INBOX’. S1: * STATUS virtual/unseen (MESSAGES 3 UIDNEXT 15186 UNSEEN 3) This is INBOX-specific because APPENDING the message to another mailbox triggers the notification on both 2.13 and 2.18 as expected: S1: * STATUS test (MESSAGES 2 UIDNEXT 3 UNSEEN 2) S1: * STATUS virtual/unseen (MESSAGES 2 UIDNEXT 15195 UNSEEN 2) I attach the ‘dovecot -n’ output for both 2.13 and 2.18. -- Guilhem.

question on autch cache parameters
by matthias lay 07 Sep '15

07 Sep '15

Hi list, I have a question on auth caching in 2.2.18. I am using acl_groups for a master user, appended in a static userdb file # snip ############################### master@uma:{SHA}XXXX=::::::userdb_acl_groups=umareadmaster allow_nets=127.0.0.1 # snap ############################### and use this group in a global ACL file. I discovered this only works on first NOT-cached login environment in imap-postlogin script on first login: AUTH_TOKEN=e96b5a32ceb2cafc4460c210ad2e92e3d7ab388c MASTER_USER=master@uma SPUSER=private/pdf LOCAL_IP=127.0.0.1 USER=pdf AUTH_USER=master@uma PWD=/var/run/dovecot USERDB_KEYS=ACL_GROUPS HOME SPUSER MASTER_USER AUTH_TOKEN AUTH_USER SHLVL=1 HOME=/var/data/vmail/private/pdf ACL_GROUPS=umareadmaster IP=127.0.0.1 _=/usr/bin/env on the second cached login it looks like this AUTH_TOKEN=12703b11932f233520f6d4b33559c33aeb1cfc7f MASTER_USER=master@uma SPUSER=private/pdf LOCAL_IP=127.0.0.1 USER=pdf AUTH_USER=master@uma PWD=/var/run/dovecot USERDB_KEYS=HOME SPUSER MASTER_USER AUTH_TOKEN AUTH_USER SHLVL=1 HOME=/var/data/vmail/private/pdf IP=127.0.0.1 _=/usr/bin/env so the ACL_GROUPS is gone. is this intended to be like that. so groups not included in cache and I have to find another approach? anybody else encountered similar problems with some auth Variables and caching?

doveadm quota recalc problem for domain
by Samuel 06 Sep '15

06 Sep '15

Hello, I've set up user quota and domain quota for dict SQL and all seems OK. New mail for user increase the user quota and the domain quota. Deleting email count down user quota and domain quota. But in case of SQL failure, I'm trying to rebuild the user quota and domain quota with doveadm quota recalc. The problem is that the command : 'doveadm quota recalc -u foo@bar' sets the domain quota only with user foo@bar even when I try a domain quota recalc : doveadm quota recalc -A or doveadm quota recalc -u *@bar (only one user is taken in account for the domain quota and not all the user). The domain SQL database is broken with value of only one user for the whole domain quota. So how to achieve rebuild domain quota correctly with doveadm ? Thanks a lot. Samuel.

Considerations for a not so simple set-up ...
by Lars Hanke 05 Sep '15

05 Sep '15

I want to set up a new IMAP server with Dovecot, so far I've been running Cyrus. I'm running dovecot on Debian Jessie. The general idea of the system would be: 1) Virtual users, i.e. login users are disjoint from any mail accounts. 2) Real-Users authenticate using their kerberos tickets. 3) There is a n-to-n mapping of real to virtual users. 4) Maildirs shall be stored on glusterfs. 5) Fallback passwords for cloud access Concerning 1) and 2) I keep reading that this is possible, but I could not find any concise and current description. I'd welcome pointers to howtos. Concerning 3) this should be a matter of ACL, e.g. a single real user (kerberos pricipal) may have several mail-boxes (virtual users), and groups of real users may share the same mail-box. I have a faint idea, how this could be done in Cyrus (but never did that), but I read that these features should exist in Dovecot as well. But I'm completely lost to even figure out a starting point. I appreciate any keywords for further reading. Concerning 4) I read that there are some issues using NFS. Are there any caveats when using gluster? Concerning 5) Users logging in from outside may not have TGT on their notebooks, which by design should run as stand-alone. They should nevertheless be able to access their mail. I currently think of another set of real users, but anything less messy is welcome. Did someone try something similar, already? Thanks for your help, - lars.

'doveadm expunge' with -A and userdb { driver = passwd }
by Grant 05 Sep '15

05 Sep '15

I'm expunging mail in my crontab like this: doveadm search -u user1 mailbox INBOX.Trash savedbefore 30d doveadm search -u user2 mailbox INBOX.Trash savedbefore 30d doveadm search -u user3 mailbox INBOX.Trash savedbefore 30d ... I'd rather do this: doveadm search -A mailbox INBOX.Trash savedbefore 30d but I'm told not to: "If the -A option is present, the command will be performed for all users. Using this option in combination with system users from userdb { driver = passwd } is not recommended, because it contains also users with a lower UID than the one configured with the first_valid_uid setting." I'm using userdb { driver = passwd-file } but I'm guessing that's the same thing. Am I understanding this correctly? - Grant

Hi (New to dovecot) I am experiencing intermittent connection failures with both apple mail and ios mail. No specific errors and I cannot find relevant information on the mac logs or on my server. It spontaneously corrects. restarting dovecot - no dice It just happened now (again), this time there might have been a reason, I just dovecot-lda'd some large mailboxes from mbox to Maildir. But as I said, it spontaneously corrects, so is downloading now. While this connection error is occurring, then I can connect to dovecot via a remote mutt session, via web imap client and via outlook. Is this a known issue? FWIW: % doveconf -n # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.19.0-26-generic i686 Ubuntu 15.04 lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = 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 } mailbox virtual/All { special_use = \All } prefix = } passdb { driver = pam } postmaster_address = postmaster(a)biovolt.nl protocols = " imap lmtp" ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = passwd } protocol lda { info_log_path = /tmp/dovecot-deliver.log log_path = /tmp/dovecot-deliver-errors.log } Thanks Eric

Reviving an old thread: "requiring client certificates for external connections"
by Robert Giles 03 Sep '15

03 Sep '15

Hi folks - reviving an old thread from 2010: http://www.dovecot.org/list/dovecot/2010-December/055837.html We're basically looking to do the same thing: require client certificates for external connections, while preserving certificate-less username/password authentication for internal connections. Any tips on the best way to accomplish this? 'ssl_verify_client_cert = yes' can go within a local {} block, but it doesn't seem to force the client to submit a certificate. Thanks in advance - Robert Giles

new server
by Franc 03 Sep '15

03 Sep '15

I am going to build a new box (2-3.000 users, 4-500 domains name (50-100 real, remaining used as redirect on the main (.it,.eu,.com,...)) . Is there any how-to or similar to follow for build an updated system? (My current boxes are based on CentoOS 6.x using included Dovecot + PostFix .rpms) I am thinking to CentOS 7.x + Dovecot + PostFix + RoundCube + Squirrel + procmail with unix users and virtual users. But I admit that systemd isn't still my best friend ... :-) In CentOS 7.x there is a default dovecot-2.2.10. Is it enough Ok or better use different rpms source? Any hints is welcomed :-) Thanks, F.

sieve filtering utf 8 strings
by Sergey Schwartz 03 Sep '15

03 Sep '15

Guys, I'm completely stuck, so asking for advice. My user has a sieve script which checks message header if it contains words in russian like 'Лист бронирования отправлен'. Pritty simple script # rule:[Отправлено] if allof (header :contains "subject" "LDS (robot): Лист бронирования отправлен", header :contains "from" "noreply(a)bgoperator.com") { fileinto "Отправлено"; } I don't have errors compiling the script or executing it via LMTP, but it doesn't work. Normally user receives messages from robot with subject encoded as quoted-printable Subject: =?UTF-8?Q?LDS_(robot):_=D0=9B=D0=B8=D1=81=D1=82?= =?UTF-8?Q?_=D0=B1=D1=80=D0=BE=D0=BD=D0=B8=D1=80=D0=BE=D0=B2=D0=B0=D0=BD?= =?UTF-8?Q?=D0=B8=D1=8F__=D0=BE=D1=82=D0=BF=D1=80=D0=B0=D0=B2=D0=BB=D0=B5?= When I send a test message via Thunderbird with required words - sieve works fine and subject is encoded in base64 Subject: =?UTF-8?B?0JvQuNGB0YIg0LHRgNC+0L3QuNGA0L7QstCw0L3QuNGPINC+0YLQv9GA?= =?UTF-8?B?0LDQstC70LXQvQ==?= It is the same text, but encodind is different - base 64 works fine and quoted-printable does not. Is it possible to have both supported for sieve ? -- Best regards, Sergey Schwartz Senior System Administrator Biblio Globus Tour Operator www.bgoperator.ru T: +7 495 5042500 ext 1532 E: sergey.schwartz(a)bgoperator.com

Hi, I'm using Dovecot 2.2.13-11 (Debian Jessie) and shared namespace (to be old Cyrus compatible setting): namespace { list = children location = maildir:/vmail/user/%%n/Maildir:INDEXPVT=/vmail/user/%n/Maildir/Shared/%%n prefix = user.%%n. separator = . subscriptions = yes type = shared } My account: milo Other account: peter After subscription, I have: /vmail/user/milo/Maildir/Shared/peter/.INBOX/dovecot.index.pvt.log After unsubscribe, file and folder still exists. Where Dovecot stores the information, that I had unsubscribed from this folder? I need this to analyze subscriptions over all mail acounts. Thank you, Miloslav

Is there anyway of replicating between more than one other instance of Dovecot. I have bidirectional replication working successfully and it seems to be reliable. I would like to replicate from one or more of these instances to one other. Is this possible? Dirk

I put up a question on serverfault first, which has the details, including a stack trace: http://serverfault.com/questions/713687/dovecot-antispam-error-storing-mail . Details also copied below. Is this a known bug? If I built dovecot from source rather than using the Ubuntu 14.04 packages, would I expect that to help? Are there any configuration details that might be relevant?
