duplicated mail in users inbox only
by Tom Priebe 07 Jul '16

07 Jul '16

Hello, one of my users has the issue that some mails seem to get doubled -- but only in their inbox. The mail is bcc'd to them and the original recipient receives one copy as intended. The log shows nothing extraordinary, postfix, dovecot and sieve are certain that they received and delivered one single mail (per user). Further research showed that the doubled mails' mailbox files have the same inode, which seems inexplicable. I'm using dovecot 2.2.13 replicated over two servers (Master-Master). Duplication seems to happen regardless of the receiving server, yet still not all mails they receive with them in bcc are duplicated. Here's doveconf -n > # 2.2.13: /etc/dovecot/dovecot.conf > # OS: Linux 3.16.0-4-amd64 x86_64 Debian 8.3 > auth_gssapi_hostname = mail.net.t-labs.tu-berlin.de > auth_mechanisms = login plain gssapi > auth_username_format = %n > auth_verbose = yes > default_client_limit = 1024 > default_process_limit = 1024 > default_vsz_limit = 512 M > doveadm_password = supersecretpassword > listen = *, [::] > log_timestamp = "%Y-%m-%d %H:%M:%S " > login_log_format_elements = user=<%u> method=%m rip=%r lip=%l > %c % > mail_location = maildir:~/Maildir > mail_plugins = " notify replication" > mail_privileged_group = mail > 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 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 { > args = failure_show_msg=yes dovecot > driver = pam > } > plugin { > mail_replica = remote:vmail@mail1.inet.tu-berlin.de > sieve = /mail/home/%u/.dovecot.sieve > sieve_dir = /mail/home/%u/sieve > sieve_max_redirects = 20 > } > postmaster_address = postmaster(a)net.t-labs.tu-berlin.de > protocols = imap sieve > service aggregator { > fifo_listener replication-notify-fifo { > user = vmail > } > unix_listener replication-notify { > user = vmail > } > } > service anvil { > chroot = empty > client_limit = 4096 > process_limit = 1 > } > service auth { > client_limit = 4096 > unix_listener /var/spool/postfix/private/auth { > group = postfix > mode = 0660 > user = postfix > } > unix_listener auth-master { > mode = 0600 > user = vmail > } > unix_listener auth-userdb { > mode = 0600 > user = vmail > } > user = root > } > service doveadm { > inet_listener { > port = 12345 > ssl = yes > } > } > service imap-login { > client_limit = 1024 > inet_listener imap { > port = 143 > } > inet_listener imaps { > port = 993 > ssl = yes > } > process_limit = 100 > process_min_avail = 2 > service_count = 50 > } > service imap { > process_limit = 1024 > } > service managesieve-login { > client_limit = 1024 > executable = /usr/lib/dovecot/managesieve-login > inet_listener sieve { > port = 4190 > } > process_limit = 1024 > process_min_avail = 20 > service_count = 1 > } > service managesieve { > process_limit = 1024 > } > service pop3-login { > client_limit = 1024 > inet_listener pop3 { > port = 110 > } > inet_listener pop3s { > port = 995 > ssl = yes > } > process_limit = 100 > process_min_avail = 2 > service_count = 50 > } > service pop3 { > process_limit = 1024 > } > service replicator { > process_min_avail = 1 > unix_listener replicator-doveadm { > group = vmail > mode = 0660 > } > } > ssl = required > ssl_ca = </etc/ssl/certs/TUB-CA.pem > ssl_cert = </etc/ssl/certs/mail.inet.tu-berlin.de.crt > ssl_cipher_list = > EECDH+ECDSA+AESGCM:EECDH+aRSA+AESGCM:EECDH+ECDSA+SHA384:EECDH+ECDSA+S > HA256:EECDH+aRSA+SHA384:EECDH+aRSA+SHA256:EECDH+aRSA+RC4:EECDH:EDH+aR > SA:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!SRP:!DSS:!RC4 > ssl_client_ca_dir = /etc/ssl/certs > ssl_key = </etc/ssl/private/mail.inet.tu-berlin.de.pem > ssl_prefer_server_ciphers = yes > ssl_protocols = !SSLv2 !SSLv3 > userdb { > driver = passwd > override_fields = home=/mail/home/%u uid=vmail gid=vmail > allow_all_users=yes > } > protocol lda { > auth_socket_path = /var/run/dovecot/auth-master > mail_plugins = " notify replication sieve" > } > protocol sieve { > managesieve_logout_format = bytes=%i/%o > managesieve_max_line_length = 65536 > managesieve_notify_capability = mailto > managesieve_sieve_capability = fileinto reject envelope encoded- > character vacation subaddress comparator-i;ascii-num eric relational > regex imap4flags copy include variables body enotify environment > mailbox date ihave > } Has anyone any suggestions what went wrong?

Please keep replies on-list. If you removed the compiler flag, how can you get error about compiler flag? Perhaps you need to contact package maintainer?

Configure Dovecot for GSSAPI [formerly: Looking for GSSAPI config]
by Mark Foley 06 Jul '16

06 Jul '16

After a over a year and a half struggling to get Dovecot to do either NTLM or GSSAPI authentication with Samba4 AD/DC, I believe I've finally got it! Thanks to all those in this list who helped: Jan Jurkus, Edgar Pettijohn, Gregory Sloop, Tom Talpey especially Aki Tuomi; and infinite thanks to Achim Gottinger on the SambaList for his patience in working this through with me. Although my purpose was for Dovecot to authenticate mail clients, the configuration settings needed were on the Samba side. I hope a variation of these instructions can eventually make it into: http://wiki2.dovecot.org/Authentication/Kerberos What is essentially missing from the wiki is how to set up the proper Service Principal Names and the subsequent creation of a dovecot useable kerberos keytab file. The wiki comment on "k5principals passdb" was not helpful and largely unintelligble to me. Perhaps like many of you, I have switched from Microsoft SBS and Exchange to Samaba4 and Dovecot/IMAP. The transition was completely transparent to my users, except they needed a separate password for email authentication in the absence of NTLM or GSSAPI working with Dovecot. A mild inconvenience, but I have been on a "quest" to fill that gap. This solution finally takes care of that last piece. The following describes how to create the SPNs and krb5 keytab files using Samba4 which has its own built-in (Heimdal) kerberos. The procedures are probably similar for other facilities such as setspn for Windows, but I've not used those so I won't attempt to discuss those mechanism here. You do need kerberos as the Samba built-in kerberos does not have needed commands like `klist`. My distro (Slackware 14.1) does not come with kerberos (nor, I think, does Ubuntu), but is easily found at: https://slackbuilds.org/repository/14.1/network/krb5/ Ubuntu/Debian: apt-get install krb5-config libpam-krb5 krb5-user ssh-krb5 (perhaps more) After provisioning Samba4, copy the krb5.conf template to /etc/krb5.conf. (Note: the actual docs advise symlinking: ln -sf /usr/local/samba/private/krb5.conf /etc/krb5.conf but I prefer making a copy in case I need to modify things). I've set The /etc/krb5.conf file to world readable. It's default contents are (and these do not need to be changed): [libdefaults] default_realm = HPRS.LOCAL dns_lookup_realm = false dns_lookup_kdc = true where HPRS.LOCAL is my realm, of course use your own. Now, we need a samba user in order to create the necessary SPNs (Server Principal Names): $ samba-tool user create dovecot New Password: Retype Password: User 'dovecot' created successfully Next, add the SPN(s), and create the keytab: $ samba-tool spn add imap/mail.hprs.local dovecot $ samba-tool domain exportkeytab --principal imap/mail.hprs.local /etc/dovecot/dovecot.keytab Dovecot does not do my (outgoing) SMTP serving, only (incoming) IMAP, but if it did I'd have to create another SPN for smtp: $ samba-tool spn add smtp/mail.hprs.local dovecot $ samba-tool domain exportkeytab --principal smtp/mail.hprs.local /etc/dovecot/dovecot.keytab Dovecot needs to be able to read the keytab file: $ chgrp dovecot /etc/dovecot/dovecot.keytab $ chmod g+r /etc/dovecot/dovecot.keytab my new keytab: $ klist -Kek /etc/dovecot/dovecot.keytab Keytab name: FILE:/etc/dovecot/dovecot.keytab KVNO Principal ---- -------------------------------------------------------------------------- 1 imap/mail.hprs.local(a)HPRS.LOCAL (des-cbc-crc) (0x232616c2a4fd08f7) 1 imap/mail.hprs.local(a)HPRS.LOCAL (des-cbc-md5) (0x232616c2a4fd08f7) 1 imap/mail.hprs.local(a)HPRS.LOCAL (arcfour-hmac) (0x9dae89a221dc374a39f560833352f60f) (and if I also created the spn for smtp I would also have these:) 1 smtp/mail.hprs.local(a)HPRS.LOCAL (des-cbc-crc) (0x232616c2a4fd08f7) 1 smtp/mail.hprs.local(a)HPRS.LOCAL (des-cbc-md5) (0x232616c2a4fd08f7) 1 smtp/mail.hprs.local(a)HPRS.LOCAL (arcfour-hmac) (0x9dae89a221dc374a39f560833352f60f) DOVECOT SETTINGS: My version: 2.2.15 Of crucial importance is to build dovecot with GSSAPI! That is NOT one of the default settings. In the dovecot build directory: ./configure --with-gssapi=yes Other than that serious build gotcha, settings are pretty simple. Add the following 3 settings to 10-auth.conf: auth_gssapi_hostname = "$ALL" auth_krb5_keytab = /etc/dovecot/dovecot.keytab auth_mechanisms = plain login gssapi The auth_gssapi_hostname is supposedly not required according to some of the above-listed commentors, but my 10-auth.conf template implies differently, so it can't hurt. gssapi does not require a passdb. Use whatever userdb you want. The dovecot wiki doc has some suggestions, not of which I've tried. I use the 'driver = passwd' for my userdb for unrelated reasons. I couldn't get any of this working until I rebooted the Samba AD/DC-Dovecot server, but that just may have been me not stopping/starting Samba and Dovecot in the right sequence (or, everything happened to start working with a concurrent upgrade to Samba 4.2!). In my WIN7 and Ubuntu Thunderbird clients I selected gssapi/kerberos for the IMAP authenticate method and it works! I've even changed the test user's AD password, just to make sure. Someone please put at least the required info on creating the SPNs and krb keytab file for other poor schmucks like me. Now, if I can get NTLM figured out for the remaining Outlook users ... ! --Mark

Postfix/dovecot: user unrecognized, file permissions being misread

Hello all. Have spent several days following the excellent tutorial: http://www.binarytides.com/install-postfix-dovecot-debian/ but still fail to have the user recognized and am getting log entries that the mail directories are 0755 when I can clearly see that they are 0774. Very puzzling, any help would be deeply appreciated. Best regards, Andy =========== Details =========== • I can add directories under IMAP, so my IMAP login and permissions must be correct. • I can create an outgoing message under IMAP, but clicking SEND just hangs. Logs do not indicate problem. • I clearly can send it a message with smtp.

duplicate Mails with dsync replication
by Dennis Kuhn 05 Jul '16

05 Jul '16

Hi! We have some strange replication issues. Some mails are duplicated when expunged. This bug is quite hard to reproduce, it just happens occasionally. It seems somehow related to sieve. When i deleted the sieve script i could not reproduce this behavior. Here are some logs, mjm-100010(a)mydomain.com is an alias for mjm(a)mydomain.com: # Master Jun 23 00:51:41 dobby4 dovecot: lmtp(mjm-100010(a)mydomain.com): copy from <lmtp DATA>: box=INBOX, uid=7816, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 00:51:41 dobby4 dovecot: lmtp(mjm-100010(a)mydomain.com): 4N23HaMVa1fpmQEAJEBNLA: sieve: msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>: stored mail into mailbox 'INBOX' Jun 23 04:52:57 dobby4 dovecot: pop3(mjm(a)mydomain.com): expunge: box=INBOX, uid=7816, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:52:57 dobby4 dovecot: dsync-local(mjm(a)mydomain.com): save: box=INBOX, uid=7817, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:55:21 dobby4 dovecot: pop3(mjm(a)mydomain.com): expunge: box=INBOX, uid=7817, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 # Replica Jun 23 00:51:42 dobby5 dovecot: dsync-server(mjm-100010(a)mydomain.com): save: box=INBOX, uid=7816, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:52:57 dobby5 dovecot: dsync-server(mjm(a)mydomain.com): copy from INBOX: box=INBOX, uid=7817, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:52:57 dobby5 dovecot: dsync-server(mjm(a)mydomain.com): expunge: box=INBOX, uid=7816, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:55:22 dobby5 dovecot: dsync-server(mjm(a)mydomain.com): expunge: box=INBOX, uid=7817, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 The problem is the "dsync-server(mjm(a)mydomain.com): copy from INBOX: box=INBOX, uid=7817" on dobby5 at 04:52:57. This creates a new uid 7817 and the new mail is replicated back to dobby4. But i have no idea what triggers this copy. Any ideas? The dovecot version is 2.2.24. Thanks Dennis

many imap connections issue
by Бауыржан Сахариев 05 Jul '16

05 Jul '16

I'm using dovecot 2.1.7 I'm trying to connect to dovecot by imap via Java mail api. My approach described here <http://stackoverflow.com/questions/37991025/why-iterating-over-all-java-mai…>. Bill Shannon, author of the Java Mail api recommended me to check carefully my server side (I have dovecot at server side). Actually, imap login in loop works but very slow. Each store.connect(login,password) takes about 1 minute. I tried to increase mail_max_userip_connections client_limit and process limit but it didn't help. My dovecot sometimes performs query, sometimes not! My logs: Jul 04 18:23:25 auth: Error: pgsql: Query failed, aborting: SELECT email, 'maildir:/home/mailboxes/maildir/'||maildir as mail,'/home/mailboxes/home/'||maildir as home, 500 as uid, 500 as gid FROM users WHERE email = 'test(a)test.domain.com' Jul 04 18:23:25 auth: Error: sql(test(a)test.domain.com,127.0.0.1,<HGiPY842jgB/AAAB>): User query failed: ERROR: permission denied for relation users My user and password queries: password_query = SELECT email as user, password FROM users WHERE email = '%u' user_query = SELECT email as user, 'maildir:/home/mailboxes/maildir/'||maildir as mail, '/home/mailboxes/home/'||maildir as home, 500 as uid, 500 as gid FROM users WHERE email = '%u' My master conf *Please note, that I'm using same uid!* service imap-login { inet_listener imap { #port = 143 } inet_listener imaps { #port = 993 #ssl = yes } # Number of connections to handle before starting a new process. Typically # the only useful values are 0 (unlimited) or 1. 1 is more secure, but 0 # is faster. <doc/wiki/LoginProcess.txt> #service_count = 1 # Number of processes to always keep waiting for more connections. #process_min_avail = 0 # If you set service_count=0, you probably need to grow this. #vsz_limit = $default_vsz_limit } service imap { # Most of the memory goes to mmap()ing files. You may need to increase this # limit if you have huge mailboxes. #vsz_limit = $default_vsz_limit # Max. number of IMAP processes (connections) #process_limit = 1024 } service auth { unix_listener auth-userdb { #mode = 0666 #user = #group = } # Postfix smtp-auth #unix_listener /var/spool/postfix/private/auth { # mode = 0666 #} # Auth process is run as this user. #user = $default_internal_user } service auth-worker { # Auth worker process is run as root by default, so that it can access # /etc/shadow. If this isn't necessary, the user should be changed to # $default_internal_user. #user = root } I'm sure that long login *reason is poor dovecot config* but some things are not clear to me and I can't improve it. 1. Which service are being used when Java connects to dovecot? imap-login,imap or auth? My assumption - imap-login. Imap user for dealing with folders *after* login, auth is for delivery (my assotioations here are postfix,lmtp,lda) =) Is my assumptions about imap-login and other services correct? 2. Which user are being used when I login? One that specified in connection code(one of 50K users in loop) or uid(500) user? I suggested that only one user and increased mail_max_userip_connections is it correct? 3. May some troubles in connection (which I showed above) caused by mode(0660) bad config in master.cf services? 4. Almost each loop iteration connects to dovecot in 60 seconds and rarely connects in a few milliseconds. Is that fact somehow connected with deafult_idle_kill which equlas to 1 mins?

v2.2.25 released
by Timo Sirainen 04 Jul '16

04 Jul '16

http://dovecot.org/releases/2.2/dovecot-2.2.25.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.25.tar.gz.sig Some minor fixes and (mainly logging) improvements since rc1. * lmtp: Start tracking lmtp_user_concurrency_limit and reject already at RCPT TO stage. This avoids MTA unnecessarily completing DATA only to get an error. * doveadm: Previously only mail settings were read from protocol doveadm { .. } section. Now all settings are. + quota: Added quota_over_flag_lazy_check setting. It avoids checking quota_over_flag always at startup. Instead it's checked only when quota is being read for some other purpose. + auth: Added a new auth policy service: http://wiki2.dovecot.org/Authentication/Policy + auth: Added PBKDF2 password scheme + auth: Added %{auth_user}, %{auth_username} and %{auth_domain} + auth: Added ":remove" suffix to extra field names to remove them. + auth: Added "delay_until=<timestamp>[+<max random secs>]" passdb extra field.

Shared mailboxes not showing up in shared namespace

Suggestions? Moving maildir to new storage and may be switch to mdbox
by Götz Reinicke - IT Koordinator 01 Jul '16

01 Jul '16

Hi, we got a new storage for our mails and now we think about the best way to use it. Currently about 1TB is stored in maildirs, some mail has been moved to client side local storage temporarily to get space on the old storage. I think of different options, some downtime in mind: a) stay with maildir and just rsync/move all mail to the new storage, mount the new storage at the old mountpoint (or may be new mountpoint and edit the dovecot config). b) "dsync backup" users maildir to mdboxes at a temp mountpoint and change the dovecot config afterwords. c) your suggestions or best practice Thanks for feedback .

v2.2.25 release candidate released

http://dovecot.org/releases/2.2/rc/dovecot-2.2.25.rc1.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.25.rc1.tar.gz.sig Quite a lot of changes. Please test out before the final v2.2.25 release, which I'm planning for tomorrow. Especially the new lib-dcrypt might have compiling problems with some OpenSSL versions. * lmtp: Start tracking lmtp_user_concurrency_limit and reject already at RCPT TO stage. This avoids MTA unnecessarily completing DATA only to get an error. * doveadm: Previously only mail settings were read from protocol doveadm { .. } section. Now all settings are. + quota: Added quota_over_flag_lazy_check setting. It avoids checking quota_over_flag always at startup. Instead it's checked only when quota is being read for some other purpose. + auth: Added a new auth policy service: http://wiki2.dovecot.org/Authentication/Policy + auth: Added PBKDF2 password scheme + auth: Added %{auth_user}, %{auth_username} and %{auth_domain} + auth: Added ":remove" suffix to extra field names to remove them. + auth: Added "delay_until=<timestamp>[+<max random secs>]" passdb extra field. The auth will wait until <timestamp> and optionally some randomness and then return success. + dict proxy: Added idle_msecs=<n> parameter. Support async operations. + Performance improvements for handling large mailboxes. + Added lib-dcrypt API for providing cryptographic functions. + Added "doveadm mailbox update" command + imap commands' output now includes timing spent on the "syncing" stage if it's larger than 0. + cassandra: Added metrics=<path> to connect setting to output internal statistics in JSON format every second to <path>. + doveadm mailbox delete: Added -e parameter to delete only empty mailboxes. Added --unsafe option to quickly delete a mailbox, bypassing lazy_expunge and quota plugins. + doveadm user & auth cache flush are now available via doveadm-server. + doveadm service stop <services> will stop specified services while leaving the rest of Dovecot running. + quota optimization: Avoid reading mail sizes for backends which don't need them (count, fs, dirsize) + Added mailbox { autoexpunge_max_mails=<n> } setting. + Added welcome plugin: http://wiki2.dovecot.org/Plugins/Welcome + fts: Added fts_autoindex_exclude setting. - v2.2.24's MIME parser was assert-crashing on mails having truncated MIME headers. - auth: With multiple userdbs the final success/failure result wasn't always correct. The last userdb's result was always used. - doveadm backup was sometimes deleting entire mailboxes unnecessarily. - doveadm: Command -parameters weren't being sent to doveadm-server. - If dovecot.index read failed e.g. because mmap() reached VSZ limit, an empty index could have been opened instead, corrupting the mailbox state. - imapc: Fixed EXPUNGE handling when imapc_features didn't have modseq. - lazy-expunge: Fixed a crash when copying failed.

Fwd: Re: Dictionary quota with Flat file database

Hello Aki, Finally I am using maildir as quota backend and it works! I set the second way like it was write here http://wiki2.dovecot.org/Quota/Maildir With this method The quota can be personalized per user manually. I only have to create the file once for the new users. But I don't know if these following options in 90-quota.ext works again : quota_rule2 = Trash:storage=+100M quota_grace = 10%% I'm going to test that. Thanks a lot!

Released Pigeonhole v0.4.15.rc1 for Dovecot v2.2.25.rc1.
by Stephan Bosch 01 Jul '16

01 Jul '16

Hello Dovecot users, This upcoming release is all about bug fixes, of which only one is really important. It affects the new imapsieve plugin. Changelog v0.4.15: - imapsieve plugin: For any mail transaction, the mailbox was opened a second time, even if no mailbox rule matched. This was unintentional, useless and caused problems when the imapsieve plugin was used with other plugins like acl. - extprograms plugin: Significantly improved error handling. No stream errors were logged. - Several small fixes based on static analysis. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.15… http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.15… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release candidate and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

quota-status service
by Michael Fox 30 Jun '16

30 Jun '16

I'm trying to understand the quota-status service, but I can't find complete documentation. The quota-status service is mentioned here: http://wiki.dovecot.org/Quota And an example configuration is shown: service quota-status { executable = quota-status -p postfix inet_listener { port = 12340 # You can choose any port you want } client_limit = 1 } But I can't find any information on quota-status. "man quota-status" returns nothing. I am unable to find a "quota-status" file on my machine. Where is the executable located? What does the "-p postfix" option do? Are there any other command line options? The above wiki page shows three quota_status_* options in use: quota_status_success = DUNNO quota_status_nouser = DUNNO quota_status_overquota = "552 5.2.2 Mailbox is full" Where are their meanings documented? What are the allowed values? Are there other quota_status_* options? Thanks in advance. Thanks, Michael

Hi all, What specifically does this flag do? Does it affect what happens: -------------- - when the drive is full? - when the system user’s disk quota is full? - when the mailbox’s quota is full? -------------- Also, does it work with both LDA and LMTP? I don’t see much on this option in the docs. Thank you! -Felipe Gasper Houston, TX

Dictionary quota with Flat file database
by Sam 30 Jun '16

30 Jun '16

Hello, I want specific quotas for certain users and I looking for doing that with dictionary quota backend and Flat file. Because I am using "active directory" with PAM for authenticate, I can't get per-user quota limits with set/override them by returning "quota_rule" extra field from userdb. I started reading http://wiki1.dovecot.org/Quota/Dict, saw some good stuff... The problem is that I don't understand how to set the limit in the users files. If I open one created file I only see the current number of messages and the actual size. Not the quota limits... vi /home/vmail/john.doe/Maildir/dovecot-quota : priv/quota/messages 13 priv/quota/storage 600201 Here is /etc/dovecot/conf.d/90-quota.conf file details : plugin { # I think I have to set the default limits here quota_rule = *:storage=10G:messages=10000 } ... plugin { quota = dict:user::file:%h/Maildir/dovecot-quota # same result with : # quota = dict:User::file:%h/Maildir/dovecot-quota } my server : CentOS Linux release 7.2.1511 dovecot : dovecot-2.2.10-5.el7.x86_64 Thanks for helping.

Unread Mail flag being reset frequently with dovecot -git master-2.2
by Reuben Farrelly 30 Jun '16

30 Jun '16

Hi again, I'm experiencing problems with the Dovecot git master-2.2 branch, in which mails that have been previously read are randomly appearing as unread. This happens slowly and affects more and more emails the more changes that occur to a mailbox. I am using Maildir format and on Gentoo Linux x86_64 on local disks. Usually only a few at a time change their status - and it seems to be random which ones lose their read status. Typically though they are the most recent emails that have been delivered in the past few months (I haven't yet seen this occur with any really old emails). This problem is MUA independent, it can be observed with Thunderbird as well as Roundcube. If I go in and mark all mails as read then they will show as read for a short while until they too slowly start become 'unread' again. Currently I'm running git rev from https://github.com/dovecot/core/commits/master-2.2 : f292589f4b85e02d97d974dfe34324c6c0bb9d9f (I can't run anything newer due to an SSL symbol error which I reported earlier). This rev: b1254dfe442639236f881afae85e0739520ab409 Is known to be good, so the problem started happening somewhere between these two. (I know there are a lot of in-between revisions, but bisecting that could take days of time). Dovecot config is up at: http://www.reub.net/files/dovecot/thunderstorm-dovecot.conf Rawlog debug files are at http://www.reub.net/files/dovecot/rawlogs/ Hopefully someone else may have seen this happen before. Are there any other debugs I can gather which will help get to the bottom of this? Reuben

Yes "dovecot purge" is certainly my mistake in the script but it really works completely analogous "doveadm purge" probably why I did not notice the difference before :) It looks like it just launches the doveadm in this case. Adding slashes after asterisks unfortunately they also adds to the variable and the script gives an error like "doveadm(user/(a)example.org/): Error: User doesn't exist" Thanks for the idea , I think it will be now more correctly : === #!/bin/sh cd /backup/MailRoot/dovecot/domains || exit 1 for i in * do if [ -d $i ]; then cd $i for j in * do if [ -d $j ]; then dovecot purge -u $j@$i fi done cd .. fi done === >Четверг, 30 июня 2016, 13:53 +03:00 от Alexander Moisseev <moiseev(a)mezonplus.ru>: > >On 30.06.16 12:51, Николай Мананков wrote: >> -----screenshot begin----- >> >> mail:/etc/cron.daily # cat ./dovepurge.sh >> #!/bin/sh >> >> cd /MailRoot/dovecot/domains >> >> for i in * >> do >> cd $i >> for j in *; do dovecot purge -u $j@$i; done >> cd .. >> done >> >> -----screenshot end ----- >> >It might be worth to add slashes after asterisks to process only directories. >Does "dovecot purge" actually work? > >-----screenshot begin----- > >#!/bin/sh > >cd /MailRoot/dovecot/domains || exit 1 > >for i in */ > do > cd $i > for j in */; do doveadm purge -u $j@$i; done > cd .. >done > >-----screenshot end ----- > >> It is strange that the daemon does not do this automatically, and even setting up autoexpunge option does not help.

[patch] Support redis AUTH
by Dave 30 Jun '16

30 Jun '16

A very minor patch to support redis AUTH (for all that's worth) using an extra password= field. I'm not sure if this will be of any value to anyone here. We're testing it in development and "it works for us" but it's yet to be used in anger. Sorry if I'm going about this the wrong way, I tried emailing this directly but heard nothing back; so I'm reposting to the list as I'm honestly not sure what established protocol is regarding code contribution. -- Dave

filtering ssl_cert
by Russell Stuart 30 Jun '16

30 Jun '16

In dovecot 1 I was able to do something like this: protocol imap { ssl_cert = cert-imap.pem ssl_key = key-imap.pem } local ww.xx.yy.zz { protocol imap { ssl_cert = cert-imap-ww.xx.yy.zz.pem ssl_key = key-imap-ww.xx.yy.zz.pem } } The intent is ww.xx.yy.zz is an externally routable IP address which has a Cert signed by a real CA, other addresses are internal which have a variety of domain names, signed by a self-signed cert. That worked in dovecot 1, but in dovecot 2 I get the error: "Conflict in setting ssl_cert found from filter". Weirdly, this works in dovecot 2: local 0.0.0.0/0 { ssl_cert = cert-imap.pem ssl_key = key-imap.pem } local ww.xx.yy.zz { ssl_cert = cert-imap-ww.xx.yy.zz.pem ssl_key = key-imap-ww.xx.yy.zz.pem } But this doesn't: local 0.0.0.0/0 { protocol imap { ssl_cert = cert-imap.pem ssl_key = key-imap.pem } } local ww.xx.yy.zz { protocol imap { ssl_cert = cert-imap-ww.xx.yy.zz.pem ssl_key = key-imap-ww.xx.yy.zz.pem } } It smells like a bug. Anyway, does anybody know of a way to port my config to dovecot 2?

Error when searching in mailfolders

Hello, I just found that with my dovecot 2.2.21, when I use squirrelmail to search for something in my mailfolders, that fails with ERROR: Connection dropped by IMAP server. Query: SEARCH CHARSET ISO-8859-1 ALL FROM "someone" That happens for searches in any folder, except from INBOX. When I search in all folders, only results from INBOX are found, then the error message is shown. The log says: imap: Error: terminate called after throwing an instance of 'CLuceneError' imap(christoph): Fatal: master: service(imap): child 2834 killed with signal 6 (core dumps disabled) What can I do about that?

[patch] Fix for returning NULL values in SQL dict lookups
by NederHost/Sebastiaan Hoogeveen 29 Jun '16

29 Jun '16

Hi, I noticed a bug doing dict lookups on an SQLite database which had NULL values in its columns; a segmentation fault occurred, probably due to a null pointer dereference in str_tabescape. The problem is that sqlite3_column_text returns a null pointer for column values which are (SQL) NULL. It seems the other database drivers do something similar. The following patch makes the dict server check for null pointers and return a 'not found' reply in those cases (I changed the order around in the decision tree to avoid having to repeat return values): diff -Naur dovecot-2.2.24/src/dict/dict-commands.c dovecot-2.2.24-patched/src/dict/dict-commands.c --- dovecot-2.2.24/src/dict/dict-commands.c 2016-04-26 15:01:20.000000000 +0200 +++ dovecot-2.2.24-patched/src/dict/dict-commands.c 2016-05-11 22:04:06.000000000 +0200 @@ -83,14 +83,14 @@ { struct dict_connection_cmd *cmd = context; - if (result->ret > 0) { + if (result->ret > 0 && result->value) { cmd->reply = i_strdup_printf("%c%s\n", DICT_PROTOCOL_REPLY_OK, str_tabescape(result->value)); - } else if (result->ret == 0) { - cmd->reply = i_strdup_printf("%c\n", DICT_PROTOCOL_REPLY_NOTFOUND); - } else { + } else if (result->ret < 0) { i_error("%s", result->error); cmd->reply = i_strdup_printf("%c\n", DICT_PROTOCOL_REPLY_FAIL); + } else { + cmd->reply = i_strdup_printf("%c\n", DICT_PROTOCOL_REPLY_NOTFOUND); } dict_connection_cmds_flush(cmd->conn); } Kind regards, -- Sebastiaan Hoogeveen NederHost https://www.nederhost.nl/ KvK: 34099781

However, it looks like that auth_failure_delay effects all connects going through that socket. I mean: connect /var/run/dovecot2.2/auth-client attempt bad auth 2s penalty NO disconnect ==> Note, it's another connection almost immediately following each connect /var/run/dovecot2.2/auth-client attempt good auth 2s penalty OK disconnect Can I disable auth_failure_delay for local UNIX sockets?

dsync unstable? (other strange detail)
by Heiko Schlittermann 29 Jun '16

29 Jun '16

Hi, I'm trying to migrate from Cyrus (remote side) to Dovecot 2.2.24 (local). On the local side the destinations folders, and indexes are empty. The command I'm using is doveadm \ -o mail_plugins= \ -o imapc_master_user=<cyrus-user> \ -o imapc_password=<cyrus-password> \ -o imapc_host=<cyrus-ip> \ \ -o imapc_ssl_verify=no \ -o imapc_ssl=imaps \ -o imapc_port=993 \ backup -f -u "heiko" -R imapc: \ || { rc=$? echo "EXIT: $rc" >&2 exit $rc } On successive runs of the above command I get: dsync(heiko): Warning: Deleting mailbox 'Serververwaltung.Mailinglisten Anforderung': UID=16 GUID= is missing locally EXIT: 75 dsync(heiko): Warning: Deleting mailbox 'Serververwaltung.Mailman': UID=2 GUID= is missing locally EXIT: 75 dsync(heiko): Warning: Deleting mailbox 'Serververwaltung.Servermeldungen': UID=514 GUID= is missing locally EXIT: 75 dsync(heiko): Warning: Deleting mailbox 'Serververwaltung.Servermeldungen.AIDE': UID=188292 GUID= is missing locally EXIT: 75 dsync(heiko): Warning: Deleting mailbox 'Serververwaltung.Servermeldungen.AIDE.AIDE - 2012': UID=9343 GUID= is missing locally EXIT: 75 Any idea where to look next? Is 'doveadm backup' the wrong tool for such migration? (I'd say with about 2.2.9 I had similar problems, but at least it didn't stop at every subfolder.)

FTS search used / useful on an IMAP proxy?
by Luca Lesinigo 29 Jun '16

29 Jun '16

We are preparing an IMAP proxy based on dovecot-2.2.22, basic proxy functionality is already working and I’m trying to understand if having the FTS service configured on the dovecot *proxy* would be of any use. I do suspect it would be useless, I guess dovecot in imap proxy mode just forwards any command to the backend and does not bother to do anything about it, but I’m failing to find a definitive answer in the documentation. If I am guessing correctly, an fts service would only be useful if configured and working on the actual backend. Can anyone clarify my doubts? thank you, -- Luca Lesinigo

Disabling passdb pam in local.conf
by Patrick Ben Koetter 29 Jun '16

29 Jun '16

Greetings, I'm trying to create a configuration that leaves every config file deployed by an install process or paket management software untouched. The goal is to put every configuration required into /etc/dovecot/local.conf. I've come quite far, but I fail to disable pam as passdb service in local.conf. What I get if I run doveconf -n is this section: passdb { driver = pam } It is in there, because 10-auth.conf includes it: !include auth-system.conf.ext These actions are not an option at the moment: - modify /etc/dovecot/conf.d/10-auth.conf and comment/remove the !include-statement - create an /etc/dovecot/dovecot.conf which would contain all options required and would not include any other *.conf files Reading http://wiki2.dovecot.org/ConfigFile I see ways to include external files, but nothing to exclude a file in local.conf. Knowing Timo I would expect there is a way to acchieve what I want. I just don't seem to find it. What am I missing?

Suggestion: Split login_trusted_networks
by Peter Mogensen 29 Jun '16

29 Jun '16

Hi, For the upcoming 2.3 development, I'd like to re-suggest this: It seems the use of login_trusted_networks is overloaded. Example: * It's used for indicating which hosts you trust to provide XCLIENT remote IP's. (like a proxy) * It's used for indicating from which hosts you trust logins enough to disable auth penalty. (like in a webmail) Often these two uses cases have a different set of hosts. So you can't have one set of hosts which you trust for XCLIENT and another set of hosts you trust for not being the origin of brute force attacks. /Peter

Where Dovecot stores subscribtions for shared folder
by Miloslav Hůla 28 Jun '16

28 Jun '16

Hi, could please someone hint me, where Dovecot stores subscribtions for shared folder? Our configuration: namespace { disabled = no hidden = no ignore_on_failure = no inbox = no list = children location = maildir:/vmail/user/%%n/Maildir:INDEXPVT=/vmail/user/%n/Maildir/Shared/%%n prefix = user.%%n. separator = . subscriptions = yes type = shared } When I subscribe to 'user.test', I'll get ~Maildir/Shared/test/.INBOX/dovecot.index.pvt.log in it. When I unsubscribe from 'user.test', file stays there and its hash is the same. Kind regards, Milo

doveadm purge -A includes users with gid outside of limits and then reports error
by Michal Hlavinka 27 Jun '16

27 Jun '16

Hi, one our user reported that when he runs "doveadm purge -A" it goes through users that don't have gid in the first_valid_gid-last_valid_git range and it reports error. For example: doveadm(dovenull): Error: user dovenull: Mail access for users with GID 996 not permitted (see first_valid_gid in config file, gid from userdb lookup). doveadm(dovenull): Error: User init failed auth/userdb-passwd.c : passwd_iterate_want_pw(...) has checks for UID range, but does not have checks for GID range. Is there any reason for this? We've added those checks (see attached patch) and all seems fine. Cheers, Michal Hlavinka

Mailboxes on NFS or iSCSI
by Miloslav Hůla 27 Jun '16

27 Jun '16

Hello, we are running Dovecot (2.2.13-12~deb8u1) on Debian stable. Configured with Mailbox++, IMAP, POP3, LMTPD, Managesieved, ACL. Mailboxes are on local 1.2TB RAID, it's about 5310 accounts. We are slowly getting out of space and we are considering to move Mailboxes onto Netapp disk array with two independent network connections. Are there some pitfalls? Not sure we should use NTP or iSCSI mounts (both open implementations are not so shiny). Thanks for sharing any experiences. Kind regards, Milo

fts_solr crashs

Hi, I´ve set up in dovecot 2.2.24-1~auto+49 (from dovecot repo) fts_solr and fts_tika - jetti8 (from Debian Jessie) and latest tika-server running on a seperate machine. But if I want to rescan all messages for reindexing for instance all attachments with "doveadm -v index -u user(a)domain.tld INBOX" with 3137 mail in the INBOX it counts and then by 2900 mails the doveadm crashes with the following error message: doveadm(user(a)domain.tld): Info: INBOX: Caching mails seq=1..3137 2900/3137doveadm(user(a)domain.tld): Error: fts_solr: Indexing failed: 500 Java heap space java.lang.OutOfMemoryError: Java heap space doveadm(user(a)domain.tld): Panic: file http-client-request.c: line 769 (http_client_request_send_payload): assertion failed: (ret == 0) doveadm(user(a)domain.tld): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x8dc1e) [0x7f269375ec1e] -> /usr/lib/dovecot/libdovecot.so.0(+0x8dc98) [0x7f269375ec98] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f26936fd02e] -> /usr/lib/dovecot/libdovecot.so.0(http_client_request_send_payload+0xc8) [0x7f2693716b88] -> /usr/lib/dovecot/modules/lib21_fts_solr_plugin.so(solr_connection_post_more+0x49) [0x7f2691c538b9] -> /usr/lib/dovecot/modules/lib21_fts_solr_plugin.so(+0x361e) [0x7f2691c4f61e] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(+0x9a17) [0x7f2692ad5a17] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(+0x9e20) [0x7f2692ad5e20] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(fts_build_mail+0x999) [0x7f2692ad6809] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(+0x1056e) [0x7f2692adc56e] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_precache+0x29) [0x7f2693a1f7b9] -> doveadm(+0x2e947) [0x7f26943be947] -> doveadm(+0x28daf) [0x7f26943b8daf] -> doveadm(+0x2989d) [0x7f26943b989d] -> doveadm(doveadm_cmd_ver2_to_mail_cmd_wrapper+0x278) [0x7f26943ba788] -> doveadm(doveadm_cmd_run_ver2+0x560) [0x7f26943c8c70] -> doveadm(doveadm_cmd_try_run_ver2+0x37) [0x7f26943c8cc7] -> doveadm(main+0x1df) [0x7f26943aa33f] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf5) [0x7f2693347b45] -> doveadm(+0x1a716) [0x7f26943aa716] I don´t see any shortages on the seperate solr machine.

This makes the # namespace visible for clients that don't support NAMESPACE extension. # "children" value lists child mailboxes, but hides the namespace prefix. #list = yes # Namespace handles its own subscriptions. If set to "no", the parent # namespace handles them (empty prefix should always have this as "yes") #subscriptions = yes } I had to put this in dovecot.conf in order for the plugin to be enabled: mail_plugins = fts fts_solr solr is reachable at localhost:8880/solr and appears to be working. Please help, any suggestions are welcome Thanks

dsync is unstable?
by Heiko Schlittermann 27 Jun '16

27 Jun '16

Hi, I'm doing a backup from a Cyrus to a Dovecot (2.2.24) instance. On the dovecot side (localhost) I'm running doveadm \ -o mail_plugins= \ -o imapc_master_user=cyrus \ -o imapc_password=<cyrus-passwd> \ -o imapc_host=<cyrus-ip> \ \ -o imapc_ssl_verify=no \ -o imapc_ssl=imaps \ -o imapc_port=993 \ backup -f -u "heiko" -R imapc: dsync(heiko): Warning: Deleting mailbox 'Trash': UID=18290 already exists locally for a different mail: highest than remote's UIDs (remote UIDNEXT=19588) The destination (local system) does not change while running backup, the remote system (cyrus) can't be stopped while running this backup. Repeating the above command sometimes helps, sometimes not. Sometimes the names of the mailboxes dsync deletes change… Any idea how to stabilize it? I'm talking about cca 4500 mailboxes.
