dovecot 2.2.25 BUG: local_name is not matching correctly
by Arkadiusz Miśkiewicz 18 Oct '16

18 Oct '16

Bug report: When using dovecot 2.2.25 SNI capability it doesn't always match proper vhost config. For example if we have such config: local_name imap.example.com { ssl_cert = </etc/certs/cert.imap.example.com.pem ssl_key = </etc/certs/cert.imap.example.com.pem } but imap client sends mixedcase SNI hostname like "IMAP.example.com" then dovecot won't match above local_name imap.example.coml config section. IMO dovecot should do case insensitive comparison. Case sensitive matching for DNS names makes little sense. -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )

Re: First steps in Dovecot; IMAP not working

Sorry, my previous message got mangled. I'm re-writing it, quoting manually. I apologize for the traffic. >(Sorry I read this list in digest form so frequently I'm half a step behind.) No problem. >No, it's quite explicit. User "webuser" has uid/gid = 1001(webuser)/1000(ftpusers). Your mail spool has permission uid/gid = root(0)/mail(8), neither of which allows webuser to write to this mail spool to creates its own mail folder. You're right (I don't have enough Unix habits, it seems...). I couldn't change this user (it must be in the ftpusers group for other purposes), so I tried adding another user for testing mail. "mailtest", the new user, is in group mail(8). In addition, I've added write permission for "others" to /var/mail. Now, I'm trying to send a message to "mailtest" from another, working, e-mail account and nothing happens. This time, "doveadm log errors" is empty. In short, I don't get any error but no mail either. >Aki Tuomi <aki.tuomi(a)dovecot.fi> replies with several solutions: >>In your configuration, dovecot uses whatever user/group returned by PAM.

Ok, I thought I had to do all of them (and didn't understand step a)). So I've done step c) by allowing everyone write access. >Or if you dynamically/frequently onboard mail accounts, and users cannot arbitrarily write into this directory, you can "chmod 1777 /var/mail/" and let dovecot auto-create it (might also want to set "lda_mailbox_autocreate = yes". I've done it right now; same problem. Since "doveadm log errors" returns an empty result, where should I look for the problem? Thank you.

That would be step 0. A good first step is to test whether you have basic authentication working (to separate out if you have a server or client issue). I assume you allow plaintext communication, but if not, substitute telnet with "openssl sclient -connect your-server:993": C: # telnet your-server 143 S: * OK [CAPABILITY ...

Maildir Expunged GUID mismatch for UID
by Steven Xu 14 Oct '16

14 Oct '16

Dovecot version:2.2.25 Since we used to keep our email files on widows server, I made the following changes in maildir-storage.h #define MAILDIR_EXTRA_SEP ',' #define MAILDIR_INFO_SEP_S ":" to "+". Everything seems working except EXPUNG, The dovecot log is flooded by messages like following: imap(xxxxx): Error: Mailbox INBOX: Expunged GUID mismatch for UID 7039 Then I read the source code, and found the following lines in maildir-sync-index.c T_BEGIN { guid = maildir_uidlist_lookup_ext(ctx->mbox->uidlist, uid, MAILDIR_UIDLIST_REC_EXT_GUID); if (guid == NULL) guid = t_strcut(filename, ':'); mail_generate_guid_128_hash(guid, guid_128); } T_END; I have to change the code to guid = t_strcut(filename, '+'); So, should MAILDIR_EXTRA_SEP be used here instead of ':'? Thanks, Steven

update dovecot-acl in all subfolders in a public folder
by Lukas Henrich 14 Oct '16

14 Oct '16

Hello everyone, right now I have problem and can't find a proper solution. But first: dovecot-version: 2.2.13 Now to my problem: A client of mine uses a public folder called "groups". In this Folder are several subfolders like "Archive", "projects", "sales" und so on. Unfortunately this client (and his employees) created thousands of subfolders within these folders. The folder "groups" is stored in /data/vmail/domain.com/. So, if i type "tree -a -L 1 /data/vmail/domain.com/groups" I get the following outpout: /data/vmail/domain.com/groups/ ??? .Archive ??? .Archive.subfolder1 ??? .Archive.subfolder2 ??? .Archive.subfolder2.subfolder3 ??? .Archive.subfolder2.subfolder4 (....) ??? .projects ??? .projects.subfolder1 ??? .projects.subfolder2 ??? .projects.subfolder2.subfolder3 ??? .projects.subfolder2.subfolder4 (...) In this groups-folder are at the moment more than 3400 folders! Now to the permissions: When the folders "Archive", "projects" and so on had been created every folder got a dovecot-acl for the permission for each user, e.g.: user=user1 kxeilprwts user=user2 kxeilprwts This worked finde, as the dovecot-acl got copied from the parent folder when the employees created new subfolders. Now to my problem I'm facing right now: This client got 2 new employees. So how can I edit all these dovecot-acl files in all subfolders where these 2 new employess schould get access to? Thank you in advance! Yours sincerely, Lukas Henrich Furthermore here is the output of dovecot -n: # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 4.4.6-1-pve x86_64 Debian 8.4 auth_username_format = %Ln disable_plaintext_auth = no lda_mailbox_autocreate = yes mail_home = /data/vmail/domain.com/%Ln mail_location = maildir:~ mail_plugins = " 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 { hidden = no ignore_on_failure = no inbox = no list = children location = maildir:/data/vmail/domain.com/%%n:INDEXPVT=/data/vmail/domain.com/%n/share… prefix = shared/%%n/ separator = / subscriptions = yes type = shared } namespace { hidden = no ignore_on_failure = no inbox = no list = yes location = maildir:/data/vmail/domain.com/groups:INDEXPVT=/data/vmail/domain.com/%n/gr… prefix = groups/ separator = / subscriptions = yes type = public } namespace inbox { inbox = yes location = mailbox Archiv { special_use = \Archive } mailbox Archive { auto = subscribe special_use = \Archive } mailbox Archives { special_use = \Archive } mailbox "Deleted Messages" { special_use = \Trash } mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Entwürfe { special_use = \Drafts } mailbox "Gelöschte Elemente" { special_use = \Trash } mailbox "Gelöschte Objekte" { special_use = \Trash } mailbox Gesendet { special_use = \Sent } mailbox "Gesendete Elemente" { special_use = \Sent } mailbox "Gesendete Objekte" { special_use = \Sent } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Papierkorb { special_use = \Trash } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Spam { special_use = \Junk } mailbox Trash { auto = subscribe special_use = \Trash } prefix = INBOX/ separator = / subscriptions = yes } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } passdb { args = scheme=CRYPT username_format=%Ln /etc/dovecot/users driver = passwd-file } plugin { acl = vfile acl_shared_dict = file:/var/lib/dovecot/db/shared-mailboxes.db sieve = ~/dovecot.sieve sieve_dir = ~/sieve } postmaster_address = admin(a)domain.com protocols = " imap lmtp sieve sieve" service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } unix_listener auth-userdb { group = vmail user = vmail } } service imap-login { inet_listener imap { port = 143 } } service lmtp { inet_listener lmtp { address = 127.0.0.1 port = 24 } unix_listener /var/spool/postfix/private/lmtp-dovecot { group = postfix user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } } ssl_cert = </etc/ssl/certs/kmux-dovecot.intern.domain.com.crt ssl_key = </etc/ssl/private/kmux-dovecot.intern.domain.com.key userdb { args = /etc/dovecot/dovecot-ldap.conf.ext default_fields = uid=vmail gid=vmail home=/data/vmail/domain.com/%n driver = ldap } userdb { args = username_format=%Ln /etc/dovecot/users driver = passwd-file } protocol lmtp { mail_plugins = " acl sieve" } protocol lda { mail_plugins = " acl sieve" } protocol imap { mail_plugins = " acl imap_acl" }

First steps in Dovecot; IMAP not working
by Marnaud 13 Oct '16

Hello, I'm new in Dovecot and am having troubles making it working. I'm trying using Outlook and Apple's Mail as the mail clients. Outlook says it can't establish a secured connection to the server (for the IMAP protocol). I'm guessing sending e-mails works but I can't check. This is my current configuration (using dovecot -n): # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-042stab116.1 x86_64 Debian 8.6 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 } passdb { driver = pam } protocols = " imap" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } service imap-login { inet_listener imaps { port = 993 ssl = yes } } ssl = no ssl_cert = </etc/ssl/certs/mail.crt ssl_key = </etc/ssl/private/mail.key userdb { driver = passwd } userdb { driver = passwd } I find abnormal I'm seeing "ssl = no" in this configuration despite the fact that I have "ssl = required" in the /etc/dovecot/conf.d/10-ssl.conf file, but I'm new to this... I have looked around the web; finally, I'm asking here, hoping it's the correct place to ask. Arnaud

Strange subscriptions added by dsync backup

Hi, We're in the process of migrating our dovecot 1.x mail server to a Dovecot 2.2.25 server. During the migration I'm moving from mbox storage to mdbox. I use the following method to do a one-way sync from our current mail server to our new mail server (command executed on the new server): doveadm -v -o imapc_host=oldserver \ -o imapc_user=$u \ -o imapc_master_user=$masteruser \ -o imapc_password="$masterpass" \ -o imapc_port=993 -o imapc_ssl=imaps \ -o ssl_client_ca_file=/etc/pki/tls/certs/ca-bundle.crt \ -o imapc_ssl_verify=yes \ -o mail_fsync=never \ -o mail_prefetch_count=20 \ backup -R -u $u imapc: $u is replaced by the username I'm migrating. The dsync command runs and exits with code 0 (all OK). However, when I look at the subscriptions file on the new server, there seem to be additional subscriptions that are not in the subscriptions file on the old server: 7b0d681945d0fc5711560000ffff90ca 7c0d681945d0fc5711560000ffff90ca 7d0d681945d0fc5711560000ffff90ca 7e0d681945d0fc5711560000ffff90ca 7f0d681945d0fc5711560000ffff90ca 800d681945d0fc5711560000ffff90ca Where do these come from? Is something wrong with the migration? It also seems that subscriptions for IMAP folders that only contain subfolders[1] are no longer present in the new subscriptions file: # diff -u sub-old.sorted sub-new.sorted --- sub-old.sorted 2016-10-11 13:42:44.175070610 +0200 +++ sub-new.sorted 2016-10-11 13:47:53.973888462 +0200 @@ -1,26 +1,26 @@ -Archive/Administration/ +7b0d681945d0fc5711560000ffff90ca +7c0d681945d0fc5711560000ffff90ca +7d0d681945d0fc5711560000ffff90ca +7e0d681945d0fc5711560000ffff90ca +7f0d681945d0fc5711560000ffff90ca +800d681945d0fc5711560000ffff90ca Archive/Administration/Conferences Archive/Announcements -Archive/Education/ Archive/Education/E02N3A Archive/Education/I0D51A Archive/Politics -Archive/Research/ -Archive/Research/FET/ Archive/Research/FET/VPH - Virtual Physiological Human Archive/Research/Grants/ICON IBBT Call 2011 Archive/Research/Grants/Marie Curie ITN 2011 Archive/Research/Grants/Odysseus Archive/Research/Grants/SymBioSysII/Funding Archive/Research/Grants/SymBioSysII/JobApplications -Archive/Research/Manuscripts/ Archive/Research/Manuscripts/ruby-ensembl-api Archive/Research/Projects/GUNZ Archive/Research/Projects/MIQAS Archive/Research/Projects/MODY Archive/Research/Projects/ruby-ensembl-api Archives -Archive/Service/ Archive/Service/EditorORC Archive/Service/Reviewing Deleted Messages Is this expected behaviour?

Auto-archiving
by ＠lbutlr 13 Oct '16

13 Oct '16

I’d like to know if there is a way to tell dovecot to 1) move messages older than # days to the Archive folder 2) rebuild the indexes 3) remove any folders that are left with no mail Preferably, I’d like this to be a action I an schedule via crontab or something to fire off for any users that want it. So, I do not want it to do this across all users and mailboxes.

Disappearing message when move to Inbox subfolder
by Simon 13 Oct '16

13 Oct '16

We are using dovecot 2.0.9 on Centos 6.5 and having the following issues for one single user/single mailbox. When an Outlook (2016) user creates a folder under their Inbox, it does not create in their mailbox (checking with webmail the folder is not there). If they drag a message to that folder in Outlook, then it disappears. Ive searched their mailbox using doveadm and its simply gone. Ive tested with webmail doing essentially the same thing and it works with no issues. Any ideas here would be most well received :) Thanks in advance, Simon

dsync replication quota2 issue
by George Kontostanos 12 Oct '16

12 Oct '16

Hello list, We are testing a configuration with 2 mail servers using dsync replication (dovecot 2.2.25 ). Everything works fine except the quota2 which is calculated wrong only on one server. Quota2 resides on different databases since each server needs to update it. The problem: The local server always updates quota2 twice on each message it receives. This happens only on one server. Updates run fine on the second. SQL Debug: Query UPDATE quota2 SET bytes=bytes+2108,messages=messages+1 WHERE username = 'user(a)domain.org' Query UPDATE quota2 SET bytes=bytes+2108,messages=messages+1 WHERE username = 'user(a)domain.org' The result on the server that runs fine mysql> select * from quota2; +----------------------------+---------+----------+ | username | bytes | messages | +----------------------------+---------+----------+ | | user(a)domain.org | 2917126 | 17 | The result on the server that has the problem: mysql> select * from quota2; +----------------------------+---------+----------+ | username | bytes | messages | +----------------------------+---------+----------+ | | user(a)domain.org | 2920317 | 19 | dovecot -n is the same on both: root@mx2:/var/log # dovecot -n # 2.2.25 (7be1766): /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.4.15 (97b3da0) # OS: FreeBSD 10.3-RELEASE amd64 ufs auth_mechanisms = plain login auth_verbose = yes default_client_limit = 2560 default_process_limit = 512 dict { acl = mysql:/usr/local/etc/dovecot/dovecot-dict-shares-sql.conf.ext quota = mysql:/usr/local/etc/dovecot/dovecot-dict-quota-sql.conf.ext } doveadm_password = # hidden, use -P to show it doveadm_port = 12345 log_path = /var/log/dovecot.log mail_debug = yes mail_home = /usr/local/vhosts/mail/%d/%n mail_location = maildir:/usr/local/vhosts/mail/%d/%n:LAYOUT=fs mail_max_userip_connections = 70 mail_plugins = quota acl notify replication mail_privileged_group = vmail mail_shared_explicit_inbox = yes 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 index ihave duplicate mime foreverypart extracttext mbox_write_locks = fcntl namespace { inbox = no list = children location = maildir:/usr/local/vhosts/mail/%%d/%%n:LAYOUT=fs:INDEX=/usr/local/vhosts/indexes/%d/%n/shared/%%u:INDEXPVT=/usr/local/vhosts/indexes/%d/%n/shared/%%u prefix = shared/%%d/%%n/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes list = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / type = private } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile acl_shared_dict = proxy::acl mail_replica = tcp:beta.sophimail.com:12345 quota = dict:User quota::proxy::quota quota_rule2 = Trash:storage=+100M sieve = /usr/local/vhosts/mail/%d/%n/.dovecot.sieve sieve_before = /usr/local/vhosts/sieve/before.d/ sieve_dir = /usr/local/vhosts/mail/%d/%n sieve_global_dir = /usr/local/vhosts/sieve/%d sieve_global_path = /usr/local/vhosts/sieve/%d/default.sieve } protocols = imap lmtp sieve sieve service aggregator { fifo_listener replication-notify-fifo { mode = 0666 user = vmail } unix_listener replication-notify { mode = 0666 user = vmail } } service auth-worker { user = vmail } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { mode = 0600 user = vmail } user = dovecot } service config { unix_listener config { user = vmail } } service dict { unix_listener dict { mode = 0600 user = vmail } } service doveadm { inet_listener { port = 12345 } user = vmail } service imap-login { inet_listener imap { port = 143 } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } process_min_avail = 0 service_count = 1 vsz_limit = 64 M } service replicator { unix_listener replicator-doveadm { mode = 0666 } } ssl_cert = </usr/local/etc/postfix/keys/domain.com.crt ssl_key = </usr/local/etc/postfix/keys/domain.com.key userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lmtp { mail_plugins = quota acl notify replication sieve notify replication } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_plugins = quota acl notify replication imap_quota imap_acl notify replication } protocol lda { mail_plugins = quota acl notify replication sieve acl postmaster_address = root } local 192.168.3.6 { protocol imap { ssl_cert = </usr/local/etc/postfix/keys/domain.com.crt ssl_key = </usr/local/etc/postfix/keys/domain.com.key } } dovecot-dict-quota-sql.conf.ext: connect = host=127.0.0.1 dbname=quota user=mailadmin password=********** map { pattern = priv/quota/storage table = quota2 username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota2 username_field = username value_field = messages } Sorry for the lengthy email, any help is very much appreciated. -- George Kontostanos ---

Detect IMAP server domain name in Dovecot IMAP proxy
by KT Walrus 12 Oct '16

12 Oct '16

I’m in the process of setting up a Dovecot IMAP proxy to handle a number of IMAP server domains. At the current time, I have my users divided into 70 different groups of users (call them G1 to G70). I want each group to configure their email client to access their mailboxes at a domain name based on the group they belong to (e.g., g1.example.com <http://g1.example.com/>, g2.example.com <http://g2.example.com/>, …, g70.example.com <http://g70.example.com/>). I will only support TLS encrypted IMAP connections to the Dovecot IMAP proxy (‘ssl=yes’ in the inet_listener). My SSL cert has alternate names for all 70 group domain names. I want the group domain to only support users that have been assigned to the group the domain name represents. That is, a user assigned to G23 would only be allowed to configure their email client for the IMAP server named g23.example.com <http://g23.example.com/>. My solution during testing has been to have the Dovecot IMAP proxy to listen on different ports: 9930-9999. I plan to purchase 70 IPs, one for each group, and redirect traffic on port 993 to the appropriate Dovecot IMAP proxy port based on the IP I assign to the group domain name in the site’s DNS. The SQL for handling the IMAP login uses the port number of the inet_listener I think this could work in production, but it will cost me extra to rent the 70 IPs and might be a pain to manage. Eventually, I would like to have over 5,000 groups so requiring an IP per group is less than ideal. I also think having Dovecot IMAP proxy have 5,000 inet_listeners might not work so well or might create too many threads/processes/ports to fit on a small proxy server. I would rather have 1 public IP for each Dovecot IMAP proxy and somehow communicate to the userdb which group domain name was configured in the email client so only the users assigned to this group can login with that username. Anyone have any ideas? For HTTP traffic, it is easy to query the host in the HTTP Request, but I don’t think IMAP traffic has such host info in it. Does the Dovecot IMAP proxy receive the hostname from the email client when exchanging SSL certs (like SNI for HTTPS)? Or, maybe I should have group domain in the username used to log in with (e.g., username+g23(a)example.com <mailto:username+g23@example.com> or username(a)g23.example.com <mailto:username@g23.example.com>). I don’t like to make the user configure their email client to log in with a name that is different than their mailbox address. It is simpler to just have them configure their email client with username(a)example.com <mailto:username@example.com> for both authorization and for the from/sender headers in the messages. Anyway, any ideas of how to set this up in production?

Outlook 2010 woes
by Bryan Holloway 12 Oct '16

12 Oct '16

Hello, everyone. We have recently begun migrating folks from an older server to a newer one, and things have been going quite well except for -- you guessed it -- Outlook 2010 users. Specifically it appears to be one customer in particular, and this particular customer has many nested mailboxes and lots of e-mail in general. Not sure if this is a factor. Old server: * Ubuntu 10.04.4 LTS * Dovecot 2.1.13 * Maildir++ * Local auth via passwd/shadow files New server: * Debian GNU/Linux 8.6 * Dovecot 2.2.13 * Maildir++ * Quotas enabled * LDAP Basically what's happening is that users are seeing large delays when navigating between different IMAP folders. So, for example, user "X" is sitting idle in their INBOX. If they then click on another folder there's a good 6-7 second delay before you can view its contents. If you immediately then navigate to other folders, you get a rapid response. But if the client then goes idle again for 10+ seconds, you will get this delay again. Some are reporting the OS saying "Outlook is not responding." (Everyone is running Windows 7.) Disclaimer: Yes, I know Outlook 2010 is a giant steaming pile of ____. However, everything worked dandy with Dovecot 2.1 and of course my customer is harping on this fact. Things I have tried/read about in the Dovecot list: * Check headers only -- doesn't seem to help. * Had a user completely remove their IMAP profile and re-add: no change. * Had a user set up an entirely new account on a new computer: same symptoms. * Someone mentioned to enable the "delay-newmail" workaround in 20-imap.conf, but this wasn't enabled in our 2.1 install, so that seems like it would not help our case. I was looking through the release notes of later Dovecots, and I noticed that in 2.2.14 there's mention of some issues with Outlook that were fixed, but it wasn't particularly specific about which versions. Should I be looking into that? And if so, is there a separate repository for newer dovecot? Currently the standard Debian 8.6 only has 2.2.13. Any help, suggestions, or pointers would be greatly appreciated. Thank you! - bryan

Problems with GSSAPI and LDAP
by Juha Koho 12 Oct '16

12 Oct '16

Hello, I have a Dovecot 2.2.25 set up with OpenLDAP back end. I was trying to set up a GSSAPI Kerberos authentication with the LDAP server but with little success. Seems no matter what I try I end up with the following error message: dovecot: auth: Error: LDAP: binding failed (dn (imap/host.example.com(a)EXAMPLE.COM)) Local error, SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (No Kerberos credentials available (default cache: FILE:/tmp/dovecot.krb5.ccache)) I have set the import_environment in dovecot.conf: import_environment = TZ CORE_OUTOFMEM CORE_ERROR LISTEN_PID LISTEN_FDS KRB5CCNAME=FILE:/tmp/dovecot.krb5.ccache And these in LDAP configuration: dn = imap/host.example.com(a)EXAMPLE.COM sasl_bind = yes sasl_mech = gssapi sasl_realm = EXAMPLE.COM sasl_authz_id = imap/host.example.com(a)EXAMPLE.COM I have tried with different values in dn and sasl_authz_id and also leaving them out completely but I always end up with the error message above. Using simple bind without GSSAPI works just fine. The credentials cache file exists and is valid for the principal imap/host.example.com(a)EXAMPLE.COM. The file is owned by dovecot user so it shouldn't be a permission problem either. GSSAPI in OpenLDAP works but I suppose it is irrelevant here since the connection attempt never reaches the LDAP server due to the error. I also have similar setup for Postfix and it works fine. Any ideas what to try next? Best regards, Juha

Managesieve port 4190 not working
by Marcio Vogel Merlone dos Santos 12 Oct '16

12 Oct '16

Hi all, I am working on a fresh install with Ubuntu 16.04 LTS and Dovecot 2.2.22-1ubuntu2.1. I am unable to open port 4190, just 2000. I have this on 20-managesieve.conf: protocols = $protocols sieve service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } } service managesieve { process_limit = 1024 } protocol sieve { mail_debug=yes } This way I get only port 2000, if comment out the "sieve_deprecated" section leaving just the "inet_listener sieve" I get nothing. Could not find anything useful on logs or strace. Any hint? Thanks in advance, best regards. -- *Marcio Merlone*

Quota & prefetch uiserDB questions
by Cédric ML 12 Oct '16

12 Oct '16

Hello, I'm trying to make quota work on my dovecot server. I'm using prefetch userdb (source : http://wiki2.dovecot.org/UserDatabase/Prefetch) with a database located on a remote host : passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } userdb { driver = prefetch } userdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } With password_query containing (source : http://wiki2.dovecot.org/Quota/Configuration) : password_query = SELECT \ username AS user, \ password, \ homedir AS userdb_home, \ maildir AS userdb_mail, \ uid AS userdb_uid, \ gid AS userdb_gid, \ CONCAT('*:bytes=', quota) AS userdb_quota_rule \ FROM mailbox \ WHERE username = '%u' When I change the quota value in DB, it's not reflected to maildirsize file of the user. If I delete maildirsize file, it's re-created but not with the quota value which is set in the DB. Questions : how is this maildirsize file created ? how is it updated ? is there a way to make maildir++ quota work with dovecot using prefetch userDB ? Or do I have to use dict quotas ? Many thanks for your help. Regards, Cédric

[imap-login] SSL related crashes using the latest 2.2.25
by Adi Pircalabu 07 Oct '16

07 Oct '16

I'm running Dovecot as proxy in front of some IMAP/POP3 Dovecot & Courier-IMAP servers and in the last couple of days I've been seeing a lot of imap-login crashes (signal 11) on both 2.2.18 and 2.2.25, all SSL related.
