autocreate mailboxes
by Mike Pultz 02 Aug '14

02 Aug '14

Hello, I just upgraded to Dovecot 2.2.13 from the 2.0 version branch- so far everything is working great. I wanted to take advantage of the mailbox option to auto create and auto subscribe users to a Sent and Trash folder (using the support for the special use flags), but ideally, I only want to do this for new mailboxes, and not for all the mailboxes that already exist on the system. The reason for this is because all the existing users likely already have a sent-mail folder configured, and I don't want to implement this, and have their sent-mail folder switched to this new one. When I set this up on my test system, I noticed that the new sent and trash folders appeared in my existing mailbox, and when I checked the account on my iPhone, it switched my sent-mail folder away from my "normal" sent-mail folder, and I couldn't change it back. Is there a way to do this ONLY when dovecot creates a new mailbox? Thanks, Mike

Advantage of LMTP
by Jerry 02 Aug '14

02 Aug '14

Sat, 2 Aug 2014 06:53:58 -0400 Presently, I have: "virtual_transport = dovecot" in my Postfix main.cf file and dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/dovecot-lda -f ${sender} -d ${recipient} in the master.cf file. Is there any advantage to using LMPT instead? All of my users are configured as virtual users. If I change it, do I have to eliminate the above from my master.cf file? -- Jerry

[Dovecot] Converting old emails to compressed format
by Renaud Allard 02 Aug '14

02 Aug '14

Hello, I know this question has already been asked, but I would really like a solution here as I tried all I could find on the wiki or mail archives I am now running dovecot 2.2.12 Compression works fine for new mails, so zlib works Mails are currently stored using dbox So I tried for testing dsync -D -v mirror -u user -m Archives dbox:~/temp dsync -o "plugin/zlib_save=xz" -D -v mirror -u user -m Archives dbox:~/temp dsync -o "plugin/zlib_save=" -D -v mirror -u user -m Archives dbox:~/temp dsync -o "plugin/zlib_save=" -D -v mirror -u user -m Archives maildir:~/temp dsync -o "plugin/zlib_save=xz" -D -v mirror -u user -m Archives maildir:~/temp And also converting again those maildir messages to dbox (just in case it wouldn't work from dbox format) And also with backup instead of mirror None of this actually works, mails are indeed copied, but not compressed So I am wondering if there is a way to compress those mails? Thank you

Configuring pigeonhole/sieve
by Timothy Murphy 02 Aug '14

02 Aug '14

I've been trying for a few days to get pigeonhole/sieve working in order to filter email with spamassassin. Unfortunately I have had no success; and I have found no document which simply tells me what changes I need to make to which files, and what other action I have to take. I'm running CentOS-7 on my home-server, and have postfix + dovecot working perfectly; moreover spam is marked with ***Spam*** added to the Subject header. The only problem is that this spam is getting through to my inbox. It's clear that I'm overlooking some action I should be taking, and I'm sure there must be a document somewhere that gives simple and complete instructions on setting up pigeonhole/sieve to work with SpamAssassin. If anyone knows of such a document I should be eternally grateful. I was told at one point that "You need to pass your mail through dovecot-lda or lmtp", but I have no idea what this means. I see in /var/log/dovecot when I re-start dovecot "Aug 02 00:13:04 master: Info: Dovecot v2.2.10 starting up for imap, pop3, lmtp, sieve, sieve (core dumps disabled", which seems to imply that lmtp is enabled. Any suggestions or advice gratefully received. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

Dovecot EE on SciLinux 6.5: No Config Files in /etc
by Asai 02 Aug '14

02 Aug '14

Greetings, I tried installing Dovecot EE on Scientific 6.5 yesterday, but there was no repo under that release version, so I hardcoded the release version to 6 in yum.repos.d/dovecot.repo. That worked, but when I installed, it didn't install any default configuration files. /etc/dovecot was empty. Is that to be expected for EE? -- --Asai

Are you implying that Dovecot 2.1.7 doesn't enable persistent modseq tracking in this case? I never claimed that earlier versions of Dovecot didn't advertise CONDSTORE or didn't implement it properly, etc. Perhaps I should have written "...after *any* of the two commands... (and maybe others)" -- meaning it does after either of those two commands, and the other ones I don't care about and so didn't test. > And as mentioned above, there are 6 different ways of enabling CONDSTORE. > (Enabling QRESYNC is done 1 way ... the "ENABLE QRESYNC" command). Yes, agreed, noted. I'm asking about two out of those five / six. And not just about what the RFC says, but about how real, out in the field, installed on mail servers that people use, possibly quite old, versions of Dovecot behave. So let me try again: Is sending SELECT ... (CONDSTORE) or STATUS (... HIGHESTMODSEQ ...) enough to enable reliable persistent modseq tracking for all versions of Dovecot which advertise CONDSTORE in their capabilities? Not what the currently relevant RFC says, but how Dovecot versions with CONDSTORE in their caps behave. This is the one thing I'd really like to know. > > > So my questions are: >> >> 1 - Is this (enabling persistent modseq) also the case for all Dovecot >> versions prior to 2.1.7 that advertise CONDSTORE? >> >> There must be people running older versions out there, older than 2.1.7. >> >> If not, how can I branch my logic to not use HIGHESTMODSEQ, given that >> Dovecot doesn't appear to return any version info via its greeting or via >> the ID command? >> > > As noted above, this is irrelevant.

However: > Returning NOMODSEQ on mailboxes that don't support persistent > mod-sequences has worked since 1.2.0, at least as far as I know. The linked message from 2012, discussing 2.0.18, says: "2) If a mailbox doesn't have modseqs enabled, return NOMODSEQ. This isn't ideal, but seems like the only possibility" And based on my tests, Dovecot 2.1.7 returns "HIGHESTMODSEQ 1" for mailboxes where modseq tracking has not been enabled. You're largely right about the value only being relevant if the client enabled CONDSTORE, and I don't care too much about this quirk, just wanted to to get a clarification on this as well, if possible.

Differences in "Delivered-To" header between deliver and LMTP
by Jeff Rice 01 Aug '14

01 Aug '14

Hi, I'm transitioning my server over from using the deliver LDA and LMTP. Suddenly a bunch of sieve filters stopped working, and I noticed the contents of the Delivered-To header are different. Using Dovecot's deliver LDA, the contents are a bare email address (foo(a)bar.com) Using Dovecot LMTP, they are in brackets (<foo(a)bar.com>). Is there a reason why this isn't consistent between the two delivery agents? It seems like it ought to be. Jeff

solr_add_definite_query quotes queries
by G H 01 Aug '14

01 Aug '14

So Solr 4.0 and higher supports regular expressions in searching. However, Dovecot is quoting search queries in solr_add_definite_query (via solr_add_str_arg). This breaks regex searching. I do a sample search for emails with "merged" in their body via the query /merg.*/. If you look at the Solr logs, it is sending: q=body:"/merg.*/" which is converted to body:\"/merg.*/\" inside Solr. but if it had sent only: q=body:/merg.*/ then regex would have worked. Is regular expression searching on the dashboard? I'm considering patching fts-backend-solr.c to not quote-enclose the search, but am looking for any better suggestions. Or perhaps not quote-enclose if the search is prefixed with RX: (ie: "RX:/merg.*/")... Thanks, G H

Issue with exim and auth protocol
by Mildred Ki'Lya 31 Jul '14

31 Jul '14

Hi, I'm trying to set up exim (4.83) as a submission server, and need to set up the dovecot authentication in exim. I'm having an issue with that (documented at <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=756258>) The problem is that exim doesn't follow the handshake as described here: <http://wiki2.dovecot.org/Design/AuthProtocol>. The wiki page says that the client should start the handshake, but exim waits for the server to start and to receive the DONE command until it starts its own handshake. What I actually get is: exim connects to dovecot auth dovecot VERSION 1 1 dovecot SPID 48 And then, dovecot stops (I presume it waits for the client handshake, VERSION and CPID). Exim on its side waits for the DONE. This results in the SMTP connection by exim never replying to the AUTH PLAIN command. This is exim 4.80 (or 4.83) and dovecot 2.1.7. I have another server set up almost exactly the same (but with dovecot 2.1.17) where it does work. In that case, dovecot finishes the handshake before exim starts its handshake. It results in: exim connects to dovecot auth dovecot VERSION 1 1 dovecot MECH PLAIN plaintext dovecot SPID 10905 dovecot CUID 1 dovecot COOKIE d3861d29441f06d962490eab8549fd46 dovecot DONE exim VERSION 1 0 exim CPID 10619 exim AUTH 1 PLAIN service=smtp secured rip=82.247.184.53 lip=80.67.179.36 nologin resp=<base64 encoded string> I don't understand what could change the dovecot behaviour in that regard. Is there a solution that would only require modifying the configuration? Thank you, Mildred

PAM and YubiKeys
by Jack 29 Jul '14

29 Jul '14

Hi List, I am trying to get authentication to Dovecot with a Yubikey OTP. I have the PAM modules installed and can successfully authenticate to ssh with the Yubikey, so I am confident that the network level and Yubikey configuration is correct. I can also authenticate to Dovecot via PAM using a plain password, however when I try to use the Yubikey authentication with Dovecot things don't go well. Network monitoring reveals that the software does not even attempt to connect to the authentication servers. My Dovecot authentication is configured as follows :- passdb { driver = pam args = failure_show_msg=yes dovecot override_fields = proxy host=1.2.3.4 master=XXXXXX pass=XXXXXX } userdb { driver = passwd-file args = username_format=%u /etc/dovecot/users } The dovecot Pam config file is :- auth sufficient pam_yubico.so id=99999 key="xxxxxxxxxxx" authfile=/etc/yubikey_mappings debug @include common-auth @include common-account @include common-session When failing to authenticate with Dovecot, the PAM debug log shows :- [../pam_yubico.c:parse_cfg(761)] called.

Missing IMAP Subfolders
by Tim 29 Jul '14

29 Jul '14

I've recently encountered an issue with my IMAP folders on Dovecot 2.0.19. When I telnet into my account and perform a list, I get the following response: A list "" "*" * LIST (\Unmarked) "." "INBOX" A OK List completed. However I know there are subfolders here and have examined the server directly via SSH and strangely: a select INBOX.Clients * OK [CLOSED] Previous mailbox closed. * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 0 EXISTS * 0 RECENT * OK [UIDVALIDITY 1394028715] UIDs valid * OK [UIDNEXT 1] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest a OK [READ-WRITE] Select completed. When I also subscribe to a couple if these which I am able to to do despite not being able to "LIST" them, I get this with LIST-EXTENDED: a04 LIST (SUBSCRIBED RECURSIVEMATCH) "*" "*" * LIST (\Subscribed \NonExistent) "." "INBOX" (CHILDINFO ("SUBSCRIBED")) * LIST (\Subscribed \NonExistent) "." "INBOX.Clients" (CHILDINFO ("SUBSCRIBED")) * LIST (\Subscribed \NonExistent) "." "INBOX.Clients.Bob" a04 OK List completed. Just not sure why a LIST is not giving me a full list as it's causing problems subscribing to these with Mail Clients. Any help is appreciated!

incremental mailbox syncs for quick migration
by Jogi Hofmüller 29 Jul '14

29 Jul '14

Hi all, We are facing quite large mailboxes (>10GB) in our migration from cyrus to dovecot. I did a test on one mailbox and repeated the sync a couple of times with the expected result that the second, third, etc. sync took only seconds compared to minutes for the first sync. We use this command to sync a mailbox: doveadm backup -R -u USER imapc: Are there any problems to be expected when we first do a sync for all mailboxes but do not migrate the users right away but instead do the actual migration using a second sync? Cheers, -- j.hofmüller http://thesix.mur.at/

problem migrating shared folders from cyrus to dovecot
by Jogi Hofmüller 29 Jul '14

29 Jul '14

Hi all, We face a problem migrating shared mailboxes from an old cyrus server to dovecot. Whereas migrating regular users works like a charm, the shared mailboxes cannot be migrated. dsync/doveadm states: "Error: Failed to access mailbox INBOX: Mailbox does not exist". This is somehow true since the shared mailboxes live not under user.mailbox but rather under shared.mailbox (cyrus special). Has anyone a solution for this peculiar problem?

Multiple servers and NFS
by Richard Hector 29 Jul '14

29 Jul '14

Hi all, For some reason, I didn't go to http://wiki2.dovecot.org/NFS until now, and I'm starting to get worried ... The plan was to have multple servers (MXes) receiving mail, and delivering via LMTP to multiple backend dovecot servers (with amavis in front of dovecot; LMTP both sides). Then we'd have multiple servers for clients to use IMAP or POP3. This is more or less how the system already works, except with Courier IMAP, and postfix on the backends, delivering to maildirs with procmail. But with the recommendation to use the Director for both IMAP/POP3 and LMTP - that starts to sound like I need a whole bunch more servers to run Directors and proxies, and even then it might not be a good idea to have different servers running lmtp and imap/pop. One possible mitigating point is that our 'load balancing' is DNS round-robin, so a given client will probably stick with a single imap/pop server anyway, but if the user has multiple clients (desktop/mobile etc) then they may still hit different servers. Can someone clarify best practice for a setup needing multiple servers for load balancing and redundancy? Is Courier already likely to have been suffering these problems? Oh, the NFS server is a NetApp Filer, if that matters. I'm using dovecot 2.2.9 from debian wheezy backports, in order to get the quota policy daemon support. Thanks, Richard

Dovecot mailstore performance tuning
by Murray Trainer 29 Jul '14

29 Jul '14

HI All, We have a couple of dovecot director proxies and six backed mailstores each accessing mailboxes stored on five NFSv4 filsystems with about 1TB of mail on each in maildir format. We have about 800 max users on each mailstore at peak times and performance appears to starting to degrade at these times. The mailstores are pretty recent hardware with 64GB of RAM and 24 cores. The NFS storage is EMC VNX and we are doing about 250 I/O per sec upto max of 500 on each filesystem. I need to squeeze more performance out of these servers whether that is in the NFS client, Dovecot or Linux OS/kernel areas. We use LDAP for auth and I am doing some tuning in that area. The NFS filesystems are mounted with the options below: 10.11.0.238:/mailbox_store_01 on /home1 type nfs4 (rw,relatime,vers=4.0,rsize=65536,wsize=65536,namlen=255,hard,nordirplus,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.11.0.96,local_lock=none,addr=10.11.0.238) My dovecot config is below. I am not seeing any obvious issues in the server logs. Any suggestions on how to improve performance would be appreciated.

Dovecot pigeonhole help sought

I'm running postfix + dovecot + dovecot-pigeonhole on my CentOS-7 home server. I would like spam to finish up in ~/Maildir/.Spam/ .

No, this is a dovecot server running in my own laptop. I guess some computer crash left the mail in an inconsistent state, and I need to assert the extend of the problem.

Segfault dovecot 2.2.9
by Simon Gareste 29 Jul '14

29 Jul '14

Hi all, When trying to set up dovecot, I somehow managed to get a segfault. Trying to launch dovecot from command line (simply execute 'dovecot') results in the error message: Segmentation fault (core dumped) Trying dovecot -n results in pretty much the same: # 2.2.9: /etc/dovecot/dovecot.conf Segmentation fault (core dumped) Looking at syslog, I see doveconf[3676]: segfault at 200 ip 00007fbb93c4fcb3 sp 00007fff005b4c10 error 4 in libc-2.19.so[7fbb93c04000+1bc000] I tried but couldn't find the core dump anywhere on the server. Any help on this would be appreciated too. I (trying to ) run it with postfix, on an Ubuntu 14.04 (Linux mail2.arturia.com 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux), brand new server. What troubles me even more is that I just set up successfully another mail server a week ago, with the same configuration (diffing the conf folders) except for log or mailbox paths (driver and stuff are the same). In the google search I've done, I saw some stuff about openssl: both servers are running 1.0.1f, since one is running fine, I guess this is not the culprit. One difference I noticed between the two servers is that on the failing one, there is no /var/run/dovecot. I presume this folder and its files are created once dovecot is launched, so that's why it's not present, and is only a symptom of the failure, not a cause? Thanks for your help, and please tell me what other information I could provide to help. Simon

Multiple passwords with sql authentication
by BlackVoid 29 Jul '14

29 Jul '14

I'm currently working on a control panel which is using postfix, dovecot and other applications and I want to add application specific passwords to increase security. I found one solution [1], however it requires the password to be included in the query which is something I do not want to do, because the query may be written in clear-text to log-files. So I'm wondering if there is a way to have multiple passwords with dovecot without risking passwords being leakied in clear-text to log-files.

Migration from mbox/maildir++ to mdbox
by Nima Saed-Samii 28 Jul '14

28 Jul '14

Dear list, dovecot version: 2.1.7 I have an old mail server that uses mboxes for the INBOX and maildirs for subfolders. I want to migrate our mail handling to a new setup using mdboxes for everything. The current config looks like this: # 2.1.7: /etc/dovecot/dovecot.conf doveconf: Warning: service anvil { client_limit=1000 } is lower than required under max. load (1127) # OS: Linux 3.2.0-0.bpo.4-686-pae i686 Debian 6.0.10 auth_mechanisms = plain login disable_plaintext_auth = no first_valid_uid = 114 log_path = /var/log/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = mbox:~/Mail/MBox:INBOX=/var/mail/%u mail_max_userip_connections = 30 mail_privileged_group = mail namespace { hidden = yes inbox = yes list = no location = prefix = "#mbox/" separator = / } namespace { location = maildir:~/Mail/Maildir prefix = separator = / } passdb { args = dovecot driver = pam } protocols = imap service auth { client_limit = 1024 user = root } service imap-login { inet_listener imap { port = 0 } process_limit = 1024 } ssl_cert = </etc/ssl/certs/cert-imap.ikp.pem ssl_key = </etc/ssl/private/key-imap.ikp.pem ssl_key_password = ********* userdb { driver = passwd } I would like to use dsync to migrate all to mdboxes and transfer them to the new system.

ACLs on Top level mailboxes.
by Dan Carroll 28 Jul '14

28 Jul '14

Hello, I’m in the process of migrating a mail server to new hardware. At the same time, I’ve made the decision to switch from courier to dovecot (v2.2.13) and from what I have seen so far I’m pretty happy. I have two questions for the list. I’d like my users mailboxes (Maildir format) to look like this: Inbox UserCreatedSubFolder1 UserCreatedSubFolder2 … Sent UserCreatedSubFolder3 Drafts Trash Junk Archives The Top level folders (Sent, Drafts etc) are all “Special” and I do not wish the users to be able to delete them. I also don’t want them to create new Top level folders. This will force all custom folders to be under a Top Level folder. The Maildir format currently looks like this: ~/Maildir/cur ~/Maildir/new ~/Maildir/tmp ~/Maildir/.INBOX/.UserCreatedSubFolder1/cur ~/Maildir/.INBOX/.UserCreatedSubFolder1/new ~/Maildir/.INBOX/.UserCreatedSubFolder1/tmp ~/Maildir/.Sent/cur ~/Maildir/.Sent/new ~/Maildir/.Sent/tmp etc…. I can get ACLs working with dovecot-acl files, and the permission I need (I think is) “owner lrwstipe”. But if I put it into the ~/Maildir directory, then it applies to Inbox. I’ve tried creating an .INBOX dir and putting it in there but that did not work. I also tried some global-acl file settings but I could not make that work either. Basically, I’m wondering how to apply ACLs to the Top level and have different ACLs for the actual inbox when using this scheme. I’m not opposed to changing the Maildir format, but that would mean a lot of work re-doing proemial scripts. My second question relates to migration. Is it enough that I copy the Maildir structure and simply delete the courier files or is it a lot better to use a courier->dovecot migration tool? I realise folder subscriptions would be lost but that’s OK, I’ll recreate them manually anyway. Thanks for your time. -Dan

After upgrade from 2.1 to 2.2.13 clients can create folders with names containing slash character on a Linux system
by David Davidov 28 Jul '14

28 Jul '14

We have following issue: After upgrade from 2.1 to 2.2.13 clients can create folders with names containing slash character. This was not possible with our previous version 2.1. Tested. Our Dovecot runs on Debian Wheezy system. According http://wiki2.dovecot.org/Plugins/Listescape this should be disabled on a Posix system. We use the usual separator '.' as you can see in the config file later. Issue can be reproduced using outlook 2013. On the file system this is the representation of the "Family/Friends" folder /home/vpopmail/domains/0/example.org/steve/Maildir/.Family/Friends /home/vpopmail/domains/0/example.org/steve/Maildir/.Family/Friends/new /home/vpopmail/domains/0/example.org/steve/Maildir/.Family/Friends/tmp /home/vpopmail/domains/0/example.org/steve/Maildir/.Family/Friends/cur Doveadm does not lists properly the folder doveadm mailbox list -usteve(a)alltimes.com |grep -i Family INBOX.Family This is the server configuration: ----------------------- dovecot -n # 2.2.13: /dovecot/etc/dovecot/dovecot.conf # OS: Linux 3.2.59-grsec x86_64 Debian 7.6 auth_username_chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890@!#$&\'*+=?^_`{|}~.-" base_dir = /var/run/dovecot/ disable_plaintext_auth = no listen = * login_log_format_elements = user=<%u> method=%m rip=%r lip=%l pid=%p %c mail_access_groups = vchkpw mail_fsync = never mail_plugins = quota stats namespace { inbox = yes location = maildir:~/Maildir:INDEX=/home/vpopmail/dovecot-indexes/%d/%n prefix = INBOX. separator = . type = private } passdb { args = /home/vpopmail/bin/chkpw driver = checkpassword } plugin { acl = vfile:/dovecot/acls quota = maildir quota_rule = INBOX.Trash:ignore stats_command_min_time = 1 mins stats_domain_min_time = 12 hours stats_ip_min_time = 12 hours stats_memory_limit = 64 M stats_refresh = 30 secs stats_session_min_time = 15 mins stats_track_cmds = yes stats_user_min_time = 1 hours } protocols = imap pop3 service imap-login { executable = /dovecot/libexec/dovecot/imap-login inet_listener imap { address = * port = 143 } inet_listener imaps { address = * port = 993 } process_min_avail = 16 service_count = 0 } service imap { executable = /dovecot/libexec/dovecot/imap-ld-hack process_limit = 1500 vsz_limit = 256 M } service pop3-login { process_min_avail = 16 service_count = 0 } service pop3 { executable = /dovecot/libexec/dovecot/pop3-ld-hack process_limit = 1500 vsz_limit = 256 M } service stats { fifo_listener stats-mail { mode = 0600 user = vpopmail } } ssl_ca = </apache/conf/ssl.crt/server-ca.crt ssl_cert = </apache/conf/ssl.crt/server.crt ssl_cipher_list = ALL:-ADH:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP ssl_key = </apache/conf/ssl.key/server.key userdb { driver = vpopmail } userdb { driver = prefetch } protocol imap { imap_client_workarounds = mail_max_userip_connections = 100 mail_plugins = quota stats acl imap_quota imap_stats } protocol pop3 { mail_max_userip_connections = 100 mail_plugins = quota stats acl pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_enable_last = yes pop3_no_flag_updates = yes pop3_uidl_format = %f } ----------------------- We need a way to prevent creation of those folders, because our users create several of them a day. Any suggestions? regards, David Davidov

by Michael Pierce 28 Jul '14

28 Jul '14

Hi, Firstly, I'd like to apologise if this is really simple or the answers available easily. I have searched and tried to solve this alone but with no success. I'm having an issue with dovecot to which its reporting "Disconnected (no auth attempts)" in the info log file. From what I understand this is usually due to SSL not being enabled (however, ssl = required is in the config). I hope someone can help. I have included config file, and log file information below. Please and Thanks, Michael Pierce ps, apologies if I was supposed to pastebin these, I was not sure. *dovecot -n* # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 3.10.9-xxxx-grs-ipv6-64 x86_64 CentOS release 6.5 (Final) auth_debug_passwords = yes base_dir = /var/run/dovecot/ disable_plaintext_auth = no first_valid_uid = 200 info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_gid = 12 mail_uid = 200 passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocols = imap ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } *dovecot-sql.conf* driver = mysql connect = host=/var/run/mysqld/mysqld.sock dbname=mailreader_mail user=[removed] password=[removed] default_pass_scheme = SHA512 password_query = SELECT email as user, password, 'maildir:/home/mail'||maildir as userdb_mail FROM users WHERE email = '%u' dovecot-info.conf Jul 28 10:58:50 master: Info: Dovecot v2.0.9 starting up (core dumps disabled) Jul 28 10:58:59 auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Jul 28 10:58:59 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so Jul 28 10:58:59 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_mysql.so Jul 28 10:58:59 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Jul 28 10:58:59 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libmech_gssapi.so Jul 28 10:58:59 auth: Debug: auth client connected (pid=22493) Jul 28 10:59:00 imap-login: Info: Disconnected (no auth attempts): rip=[removed], lip=[removed]

mdbox "doveadm purge" strategy
by Jesus Cea 28 Jul '14

28 Jul '14

Hi there. I am using mdbox storage with great success but I am seeing something I find strange and I would like to compare notes with you. When doing "doveadm purge", "m.*" files with non deleted messages are left alone, but "m.*" files with deleted messages copy the "non deleted" messages to a newly created "m.*" file and delete the original. Good so far. What surprises me is that the newly created "m.*" files are not fullsize. they can be "small" files, not using the 2MB max size I have configured for mdbox storage. Moreover, those files stay in that size forever, no new messages are appended ever. I guess each old "m.*" file with deleted messages generates a new independent "m.*" containing only the non deleted messages. I wonder if that is the case and if that is a fundamental issue that can't be changed. I would like my "m.*" files to use the full configured mdbox size, instead of having quite a few of new SMALL "m.*" files. Thanks for your time and attention!. -- Jesús Cea Avión _/_/ _/_/_/ _/_/_/ jcea(a)jcea.es - http://www.jcea.es/ _/_/ _/_/ _/_/ _/_/ _/_/ Twitter: @jcea _/_/ _/_/ _/_/_/_/_/ jabber / xmpp:jcea@jabber.org _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz

struggling with pigeonhole date extensions
by Laeeth Isharc 27 Jul '14

27 Jul '14

I am struggling with how to use the date extension for Dovecot/Pigenhole implementation of Sieve email filtering language. I have read RFC 5260 several times and tried different things with no luck. I would like to place all messages this year up till the end of March into the specified mail folder. What the snippet below actually seems to do is take any messages this year (whether before or after March). Any thoughts? if allof(date :value "eq" :originalzone "date" "year" "2014", date :value "le" :originalzone "date" "month" "3") { fileinto "INBOX/2014 up to Mar"; stop; } Incidentally, it's puzzling how sparse the ecosystem seems to be for managing sieve scripts given the importance of email and the unmanageability of volumes these days without rules. What would be nice to have is something like the Outlook rule manager as a front end and server side sieve scripts on the back. I looked at Modoboa (which seems to be the only standalone option), but it's a bit heavy for my taste and I struggled to configure it in the time I had available. Thanks in advance.

IMAP forward boxes
by Andre Dietrich 26 Jul '14

26 Jul '14

Hi all, since a few weeks I'm experimenting with some "IMAP forward boxes", but I didn't find a satisfactory solution yet. Target function is a directory structure like following in a shared mailbox: /intern/users/fred /intern/users/ted /intern/users/alice The idea is, that a mail, moved to the directory "/intern/users/fred" via IMAP-client will be forwarded to "fred(a)test.domain" without modifying the mail (except the header line "delivered to:"). So if you get a mail in your inbox and want fred to answer it, you drag'n'drop it to /intern/users/fred. Fred gets the mail in his inbox and can answer it. To share all inboxes, to drop mails directly to them, is not an option, because I don't want everybody to see all other inboxes mails. Only to apply "-w-" ACL rights isn't an option either, because it seems to irritate the mail clients. Some month ago I had a partially working solution using a cron bash script. The script read the mails in the cur and new folders, processed the folders path and passed it to sendmail. It's ok, but it has to run quite often to get an adequate forwarding time and on sendmail errors mails got lost without any notification. It would be nice to have a dot-forward file in this subfolder (like in the qmail mailbox root), which is processed by dovecot when a mail is dropped in. Is it possible to solve this with a sieve script, a dot-forward file, or something similar ? I'm grateful for all solutions / ideas ! thx! Andre

Pigeonhole Sieve LDAP support
by Stephan Bosch 25 Jul '14

25 Jul '14

Hi, Yesterday, I committed two important and rather big changes to the Pigeonhole repository. The first creates a generic interface for implementing Sieve script storages. It was already possible to some extent to read Sieve scripts from other sources than the local filesystem, such as Dovecot dict, but that was still pretty limited, as it was not possible to do this with sieve_before/sieve_after. This is now supported. But, more importantly, ManageSieve did not support storing Sieve scripts on locations other than the local filesystem. Now, alternatives can be implemented. Still, I haven't actually implemented write access to a storage other than the local filesystem yet, but now this would be much easier to achieve. The second creates an LDAP script storage implementation. Much like the dict storage, it is still read-only. It can be compiled directly into the Sieve interpreter, and, alternatively, it can also be compiled as a plugin called sieve_storage_ldap. I've updated the documentation in the sources. For all Xi repository users: I added compilation of LDAP storage as a plugin. Read the INSTALL files and other files referenced therein for more information about how to use the plugin. The plugin is installed as part of the dovecot-ldap package. This is a rather big change, but it should all be backwards compatible in terms of configuration. If you have problems (I heard about one so far), please don't hesitate to notify me. Regards, Stephan.

Maildir migration - using separate INDEX and CONTROL directories?
by Richard Hector 24 Jul '14

24 Jul '14

Hi all, I'm working on a migration from Courier to Dovecot, and the courier-dovecot-migrate.pl seems to work ok, but it puts all the metadata files (dovecot-uidlist etc) in the Maildir, while I want to put them in the appropriate places as specified: mail_location = maildir:~/Maildir:INDEX=/var/mail/meta/index/%d/%1n/%1.1n/%n:CONTROL=/var/mail/meta/control/%d/%1n/%1.1n/%n http://wiki2.dovecot.org/Quota/FS explains why some of these files need to go in different places (which is why I'm doing it), but I haven't seen a complete list of what files will be moved as a result of those directives. Is there a handy tool to move the files to the right places? Or is there a complete list of what files need to go where? Thanks, Richard

Sieve plugin (fc17 + sendmail + roundcube)
by Franck CALLEJA 24 Jul '14

24 Jul '14

Hello, I'm trying to configure sieve plugin on my mail server so that people can do mail filtering (and mostly vacation notification) on their account. The mail server is running fine since 5 years and is based on :- sendmail- dovecot- roundcube It serves 2 differents domains. I've recently installed pigeonhole for fc17, and managed to configure managesieve plugin in roundcube successfully. Users can now manage filters from roundcube. The problem is that filters are not applied when new mails arrives. I've modified dovecot.conf to activate sieve plugin, and the configuration is as follow : # dovecot -n# 2.1.16: /etc/dovecot/dovecot.conf# OS: Linux 3.8.13-100.fc17.x86_64 x86_64 Fedora release 17 (Beefy Miracle) log_path = /var/log/dovecot.logmail_debug = yesmail_location = mbox:~/mail:INBOX=/var/spool/mail/%umanagesieve_notify_capability = mailtomanagesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihavembox_write_locks = fcntlnamespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = }passdb { driver = pam}plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve}protocols = imap pop3 lmtp sieveservice imap-login { service_count = 0}service lmtp { executable = lmtp -L}service pop3-login { service_count = 0}ssl_cert = </etc/pki/dovecot/certs/dovecot.pemssl_key = </etc/pki/dovecot/private/dovecot.pemuserdb { driver = passwd}protocol lmtp { info_log_path = /var/log/dovecot-lmtp.log mail_plugins = " sieve"}protocol lda { mail_plugins = " sieve"} In /etc/sendmail.cf I've this configured :# cat /etc/mail/sendmail.mc divert(-1)dnl include(`/usr/share/sendmail-cf/m4/cf.m4')dnl VERSIONID(`setup for linux')dnl OSTYPE(`linux')dnl define(`confLOG_LEVEL', `15')dnl define(`confDEF_USER_ID', ``8:12'')dnl define(`confTO_CONNECT', `5m')dnl define(`confTRY_NULL_MX_LIST', `True')dnl define(`confDONT_PROBE_INTERFACES', `True')dnl define(`PROCMAIL_MAILER_PATH', `/usr/bin/procmail')dnl define(`ALIAS_FILE', `/etc/aliases')dnl define(`STATUS_FILE', `/var/log/mail/statistics')dnl define(`UUCP_MAILER_MAX', `2000000')dnl define(`confUSERDB_SPEC', `/etc/mail/userdb.db')dnl define(`confPRIVACY_FLAGS', `authwarnings,novrfy,noexpn,restrictqrun')dnl define(`confAUTH_OPTIONS', `A')dnl define(`confMIN_QUEUE_AGE', `15m')dnl define(`confTO_QUEUERETURN', `5m')dnl define(`confMAX_MESSAGE_SIZE', `15000000')dnl define(`confDONT_BLAME_SENDMAIL', `forwardfileingroupwritabledirpath,ForwardFileInUnsafeDirPath,ForwardFileInUnsafeDirPathSafe')dnl define(`confTO_IDENT', `0')dnlFEATURE(`no_default_msa', `dnl')dnl FEATURE(`smrsh', `/usr/sbin/smrsh')dnl FEATURE(`mailertable', `hash -o /etc/mail/mailertable.db')dnl FEATURE(`virtusertable', `hash -o /etc/mail/virtusertable.db')dnl FEATURE(`genericstable',`hash -o /etc/mail/genericstable.db')dnlGENERICS_DOMAIN_FILE(`/etc/mail/generics-domains')dnlFEATURE(redirect)dnl FEATURE(always_add_domain)dnl FEATURE(use_cw_file) FEATURE(use_ct_file)dnl FEATURE(local_procmail, `', `procmail -t -Y -a $h -d $u')dnl FEATURE(`access_db', `hash -T<TMPF> -o /etc/mail/access.db')dnl FEATURE(`blacklist_recipients')dnlEXPOSED_USER(`root')dnl DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnlFEATURE(`accept_unresolvable_domains')dnl FEATURE(`relay_hosts_only')dnl FEATURE(`dnsbl', `ipwhois.rfc-ignorant.org',`"550 Mail from " $&{client_addr} " refused.

Migration from mbox/maildir++ to mdbox
by Nima Saed-Samii 24 Jul '14

24 Jul '14

Dear list, dovecot version: 2.1.7 I have an old mail server that uses mboxes for the INBOX and maildirs for subfolders. I want to migrate our mail handling to a new setup using mdboxes for everything. The current config looks like this: # 2.1.7: /etc/dovecot/dovecot.conf doveconf: Warning: service anvil { client_limit=1000 } is lower than required under max. load (1127) # OS: Linux 3.2.0-0.bpo.4-686-pae i686 Debian 6.0.10 auth_mechanisms = plain login disable_plaintext_auth = no first_valid_uid = 114 log_path = /var/log/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = mbox:~/Mail/MBox:INBOX=/var/mail/%u mail_max_userip_connections = 30 mail_privileged_group = mail namespace { hidden = yes inbox = yes list = no location = prefix = "#mbox/" separator = / } namespace { location = maildir:~/Mail/Maildir prefix = separator = / } passdb { args = dovecot driver = pam } protocols = imap service auth { client_limit = 1024 user = root } service imap-login { inet_listener imap { port = 0 } process_limit = 1024 } ssl_cert = </etc/ssl/certs/cert-imap.ikp.pem ssl_key = </etc/ssl/private/key-imap.ikp.pem ssl_key_password = ********* userdb { driver = passwd } I would like to use dsync to migrate all to mdboxes and transfer them to the new system.

doveconf option "-e"
by Django [BOfH] 24 Jul '14

24 Jul '14

Hi Timo, If I could tell you a little smart wish, I've one for you. ;) Today I'm writing my own configurationdocumentation 'bout Dovecot in my dokuwiki and for documentation purposes I changing some options several times a day. Postfix supports on its own postconf an option -e. So I can set up mostly every configuration-option on the fly. Dovecot's doveconf has no such option. So, I changed the configuration-files and reload my dovecot-daemon. It were grait if doveconf has a similar function, like postconf's option "-e". Maybe you can make a little update to doveconf in one of the upcomming releases? ;) Best regards Django -- "Bonnie & Clyde der Postmaster-Szene!" approved by Postfix-God http://wetterstation-pliening.info http://dokuwiki.nausch.org http://wiki.piratenpartei.de/Benutzer:Django

Problems with custom plugin
by Lukas Mika 24 Jul '14

24 Jul '14

Hi everybody, I wrote a plugin for Dovecot 2.1.something which was based on the information found at http://wiki2.dovecot.org/Design/Storage/Plugins and by studying the mail_log plugin. My plugin can be found here: https://github.com/dim-0/dovecot-mbc It takes the notify plugin's information, that a new mailbox has been created (or an old one been renamed) in order to trigger a custom script (which in my case sets default ACLs for shared mailboxes). This plugin went quite well for a while, but then I recently upgraded Dovecot to version 2.2.9 and now I cannot build my plugin anymore. I get two error messages which both describe the same thing: src/mbc-plugin.c: In function ‘mbc_mailbox_create’: /usr/include/dovecot/src/lib/module-context.h:46:67: error: ‘struct mbc_user_module’ has no member named ‘reg’ COMPILE_ERROR_IF_TYPES_NOT_COMPATIBLE(OBJ_REGISTER(obj), (id_ctx).reg) src/mbc-plugin.c: In function ‘mbc_mail_user_created’: /usr/include/dovecot/src/lib/module-context.h:46:67: error: ‘struct mbc_user_module’ has no member named ‘reg’ COMPILE_ERROR_IF_TYPES_NOT_COMPATIBLE(OBJ_REGISTER(obj), (id_ctx).reg) Obviously the module context nowadays expects another attribute/struct named "reg". However, I cannot find any information about this within the documentation and plugin mentioned above. The only clue I have got yet is the definition in module-context.h: union STRUCT_NAME_module_context { struct STRUCT_NAME_module_register *reg; // it's allowed to have some structure here so it won't waste space. // for example: struct STRUCT_NAME_vfuncs super; }; However, I still cannot make any sense of it (yet). Could you please help me in filling the gap and understanding, what has to be changed? Thanks a lot in advance for an awesome piece of software and any input on this topic, Lukas

Dovecot GMail API
by Timo Sirainen 23 Jul '14

23 Jul '14

Hi all, I'm still (mostly) on vacation this week and afterwards lots of different things to do .. But hopefully I'll still get around to answering all the pending mails in this list and applying some of the patches people have sent and get the next v2.2.14 release out. Anyway, people have kept asking about GMail API and Inbox App and how that affects Dovecot. For a while now I've been planning on implementing some kind of a HTTP API for mail access, so might as well use GMail's: http://www.dovecot.fi/dovecot-launches-a-gmail-api-compatible-rest-api-to-e…

SSL certificate problem (SSL alert number 42)
by Boyandin Konstantin 23 Jul '14

23 Jul '14

Hello, After client (Thunderbird, now version 31.0) updated today, it stopped connecting to Dovecot IMAP4S. The infamous "SSL alert number 42" is reported. Mail server uses local (created for intranet) CA certificate as root. I would appreciate pieces of advice on how to handle that without enabling plaintext authentication over insecure channels. Other intranet services work with this local CA quite fine. Thank you in advance.

[patch] enable ECDH auto functions based on feature defines, not on version number
by Hanno Böck 22 Jul '14

22 Jul '14

Hello, I recently tried to build my system with libressl instead of openssl. In dovecot one issue that popped up was that libressl doesn't have the ECDH auto functions from openssl 1.0.2 beta versions. However as the #ifdef's in dovecot's code check for the openssl version and libressl's version numbers are higher the compilation fails there. Attached is a patch that will change that checks. Instead of checking for the version number it checks for the availability of the feature itself (by checking for the define of SSL_CTRL_SET_ECDH_AUTO). This should make this check more robust and work independently of the version number of the used openssl instance. cu, -- Hanno Böck http://hboeck.de/ mail/jabber: hanno(a)hboeck.de GPG: BBB51E42

BUG: Authentication client sent unknown handshake command
by Lukas Haase 22 Jul '14

22 Jul '14

Hi, Some time ago my dovecot started to become BUGgy: Evertime I restart the system, dovecot is started but I cannot login. I see the following information in the logs: Jul 4 04:04:36 mail dovecot: auth: passwd-file(user,127.11.91.218,<nfkQjFT9vwCADFra>): no passwd file: /etc/dovecot/imap.passwd Jul 4 04:04:36 mail dovecot: auth: Error: BUG: Authentication client sent unknown handshake command: REQUEST?1183186945?20438?1?a8c7241e7b0778f9f0125da760cd16fa Jul 4 04:04:36 mail dovecot: imap: Error: Authentication server didn't send valid SPID as expected: MECH#011PLAIN#011plaintext Jul 4 04:04:36 mail dovecot: imap: Error: Disconnected from auth server, aborting (client-pid=20438 client-id=1) Jul 4 04:04:36 mail dovecot: imap-login: Internal login failure (pid=20438 id=1) (internal failure, 1 succesful auths): user=<user>, method=PLAIN, rip=127.11.91.218, lip=73.82.101.172, mpid=20439, TLS, session=<nfkQjFT9vwCADFra> It does not help to restart the client. But when I then restart the server service dovecot restart it works again. But this is very dangerous because the server might reboot and I might not immideately have the chance to restart dovecot manually. What's going on here? mail:/# uname -a Linux mail 2.6.32-openvz-042stab090.2-amd64 #1 SMP Sat Jun 21 00:22:42 MSK 2014 i686 GNU/Linux mail:/# dovecot --version 2.1.7 Thanks, Luke

subfolders in public mailboxes
by Burak Arslan 21 Jul '14

21 Jul '14

Hello, I added this to the configuration: namespace { type = public separator = . prefix = public. location = maildir:/var/mail/public subscriptions = no list = yes } and I can list maildirs inside these folders correctly. however, I can't see any subfolders. The issue seems to be that /var/mail/public dir itself is interpreted as a maildir directory. However, what I'd like to do is to have a bunch of directories inside /var/mail/public and treat them as separate maildirs. (I'd like to use this to make a few existing mailboxes public) is this possible? Best regards, Burak

Mailboxes not showing up in MS Outlook
by Jerry 21 Jul '14

21 Jul '14

Sat, 19 Jul 2014 15:03:03 -0400 I am not sure exactly where the problem is here. I am using a sieve script that sorts various incoming messages into their own mailbox.

Dovecot Replication: First Run
by Asai 19 Jul '14

19 Jul '14

Greetings, I'm working on building a redundant Dovecot server which will be replicated with my original. I would like to know if there's any potential problems I could run into in running this for the first time. For example, during an initial sync is it possible for the new server to sync improperly with the original and delete all of the emails on the original? Are there any gotchas that I should be aware of when doing a first run? -- --Asai

Difference btw. Dovecot Director and Dovecot Proxy
by Nathan Schultheiss 19 Jul '14

19 Jul '14

Hello, For a few days I try to understand what program (Dovecot Director or Dovecot Proxy) I should use for my email architecture. We are a hospital, and for security reasons, we must host ourselves our emails, and we must leave Google Apps... I wish to make a Dovecot backend for each department of the hospital. Each backend Dovecot has a local storage. Server 01: cardiology Server 02: emergency ... Server 05: administration Dovecot looks in the database which server to use to store email (lmtp) and transfer the mail for storage. I do not understand if I have to work with Dovecot Director or Proxy if I would that LMTP or IMAP request are forwarded to the right backend. Each have self storage and have not access to the other backend storage (no nfs, no network storage, ...). Users indicate imap.hospital.local, this point to Dovecot Director or Proxy and Dovecot check the login/password and forward the user to the right backend. In my database I put user@hospital = storage host 172.16.2.10 = folder /home/vmail/user/ (Maildir) I've read that the Director can refer the user to the same backend when there is a activ session (POP, IMAP, LMTP) But can we tell him to always refer the user to the same backend (IMAP and LMTP) ? I've found this picture schema who user have Dovecot Proxy => Dovecot Director => Dovecot Backend And I'm confused why they have proxy + director ?!? Can anyone tell me if I need to focus on Dovecot Director or Dovecot Proxy to create the architecture of this hospital ? My question is probably stupid for Dovecot sysadmin, but I'm lost in the WIKI :) Thanks in advance, Nathan

Postfix user@domain splitting
by Ricardo Branco 18 Jul '14

18 Jul '14

I have been trying looking though all the wiki documents to setup LMTP. It now seems to all be connected except that it keeps saying that the user is not recognised when postfix sends to LMTP, it sends the full recipent email address but seems that on the dovecot side it is unable to work with this. I have checked the userdb and made sure its using %n but alas it still does not work. Currently ive had to revert to using LDA as it works fine with that but i still dont know how as the postfix config variable $RECIPIENT is the full email address and does not seem to matter to LDA.

Dovecot/K9/Thunderbird IMAP interaction issues: replicated messages, constant reloading (TB) & missing new messages (K-9)
by David Gessel 18 Jul '14

18 Jul '14

Version Info: FreeBSD 9.2-RELEASE #0 r266046 AMD64, Dovecot 2.2.13, dovecot-pigeonhole-0.4.3, amavisd-new-2.8.0_2,1, clamav-0.98.4, postfix29-2.9.9_1,1, postfixadmin-2.3.6, spamassassin-3.4.0_12 (zpool data and output of dovecot -n at bottom of post) I suspect these are related problems and further that they are related to some trivial newb error I've made in my configuration, but searching descriptions of the symptoms has not yet guided me to a solution. I recently migrated from Courier to Dovecot on new hardware and imap synced a 16GB mailstore (du -hs) divided up into annual directories with about 15,000 messages each. I mention the size because it seems an errant Remove Duplicate Messages (Alternate) 0.3.9 acting on what seem to be false duplicates in Thunderbird reduced the inbox size from 7500-ish messages to 1300 (DOH!) and may have solved my K-9 problem described below. My old Courier server still has the vast majority of these messages and I will resync someday and then try to file them away more expediently than my previously somewhat lazy management style to keep the inbox small. * In thunderbird, I get constant downloading of messages. Every time I switch to the inbox from another folder, the messages start redownloading. This sometimes, but not always, seems to create duplicate messages, but I'm now fairly sure they are only created in the client and not on the server. Searching through various forums, it appears this has been a problem for Thunderbird for some time, but it wasn't for me on Courier. As posts about similar errors seem to have petered out over the last year without any clear guidance on how to fix it that I could find, I expect there's a simple fix I just haven't found yet, either in TB configuration or in Dovecot. Any hints? I tried Thunderfix to remove the .msf files and will be redownloading my mail over the thin pipe out to Iraq for the next 6 months (DOH!). One artifact is that when I restart thunderbird, my inbox is reported as having about 130 messages in it, then thunderbird starts redownloading headers and eventually gets back up to the 1297 currently listed both in the TB pane and by ls | wc -l in /cur. Is it possible there is a time out that needs to be extended? In TB, I've set (among other less apparently relevant options) mailnews.tcptimeout;1000 mail.db.idle_limit;30000000 * Also, with Thunderbird, I get duplication of messages in the client. I suspect this is related to the previous redownload error, but there is some indication in some posts that it is potentially related to a dirty flag. I've had this problem before with Thunderbird and Courier, but it went away after a TB update. It seems to have reappeared with Dovecot. The TB client hasn't been updated during the transition, so some interaction issue seems more likely than a pure TB bug. Likely TB's fault as this is a well known, but poorly diagnosed TB issue (deleting duplicates regularly seems to be the solution, but my inbox would double in size every few hours on the LAN. Now that I'm remote over a 2mbps link, it has slowed way down: bonus!). * "Expunged message reappeared, giving a new UID" errors appear a lot. This might well be related to the last error. This seems to happen with TB client connections, but I'm not sure what action triggers it. I am not replicating. I tried renaming 10-director.conf to 10-director.conf.disabled and got no complaints from Dovecot (as I'm not using replication, it shouldn't) but that indicates that this Expunged message reappeared error is probably of a different source than, for example, Simon Fraser's debug effort. * K9 was only showing a subset of my messages and generally not the new ones. They'd appear in the alert properly, but weren't visible in the client and sometimes they'd be visible and then disappear later. I imagined there could a correlation between TB checking mail and perhaps moving messages from /new to /cur and K9 losing track, but the potentially tragic "duplicate" removal may have reduced my inbox to a size that k9 can handle as K9 inbox display seems normal now as far as I can tell. When I resync (assuming I can), I sort of dread this problem reappearing. K9 worked as expected against Courier with the same inbox. These apparently difficult to diagnose problems are occasionally suggested as related to namespace configuration issues and thunderbird is reported to have issues with some separator options. I vaguely suspect this, but I'm pretty sure my namespace config is default and should be well tested. I haven't, for example, explicitly stated the default "/" but left it commented out. I increased the connection limit count per user*IP to 20 as TB seems to be parallel downloading a lot of folders. This has neither improved nor degraded performance in any way I can see and is probably irrelevant. Any hints greatly appreciated.

Sieve: adding Date: header when missing
by Daniele Nicolodi 17 Jul '14

17 Jul '14

Hello, there is a way with a sieve rule to add a Date: header when it is missing? Adding one with the time of reception of the message or using the date from the the first Received: header would be good options. Unfortunately I'm receiving some useful automated messages that lack a Date header and this screws up the sorting in my imap clients. I have a script to fix those acting on the Maildir storage, but I would prefer to have the thing solved more radically. Thanks. Cheers, Daniele

If local Dovecot stops working, check lo
by Steve Litt 17 Jul '14

17 Jul '14

Hi all, You probably know this already, but just in case... Let's say you have your email client getting mail from a Dovecot server on the same computer (which is a really good way of doing things, by the way). Then one day your email client starts saying "connection refused" after a suitably long timeout. So then, to find out where things are getting stuck, you do the following command: openssl s_client -connect 127.0.0.1:993 -quiet And you don't even get an OK back. This means it's not your username or password, because you never even got that far. Before spending a lot of time doing diagnostic tests and narrowing it to the root cause, try this as root: ifdown lo ifup lo A malfunctioning lo will cause Dovecot not to connect to clients. My experience with Debian Wheezy is that lo "goes down" a lot, so this is one of the first things I do when odd stuff happens.

Resource Temporarily Unavailable on replicator-doveadm

We're running 2.2.13 on two servers with replication. Still trying to get my replication tweaked correctly and I’m noticing a bunch of these errors for the same users over and over again: dsync-server(user(a)host.com): Error: write(/var/run/dovecot/replicator-doveadm) failed: Resource temporarily unavailable The 5-7 that I see all have quite a number of individual mailboxes (20+), I’m wondering if that has something to do with it?

Hi! I got this error when build dovecot from source (rev 17627), configure it as imapc proxy (http://wiki2.dovecot.org/HowTo/ImapcProxy) and run imaptest with clients=2 or more, on latest stable version (2.2.13) and with clients=1 this error does not occurred.

Sending emails using dovecot auth
by Murray Trainer 16 Jul '14

16 Jul '14

Hi All, I have noticed that dovecot / exim on Cpanels appear to support sending emails via exim after authenticating to Dovecot - see message below 550-Please turn on SMTP Authentication in your mail client, or login to the 550-IMAP/POP3 server before sending your message We are migrating users mail off cpanels into split mta and dovecot servers and are having problems with some users being abble to send emails afterwards. Does anyone understand how the CPanel config works? Thanks Murray

Not only is http://atrpms.net/name/dovecot/ empty, but: http://packages.atrpms.net/dist/el6/ seems to return a 404.

Dovecot2 Antispam MAILTRAIN backend with SpamAssassin
by Mohammad S. Babaei 15 Jul '14

15 Jul '14

Hi there, I've already asked this question on FreeBSD forums without getting any response. So, I thought it's a good idea to ask it again here. I've setup Dovecote2 (2.2.13) + Postfix + SpamAssassin on my FreeBSD 10 VPS and it works flawlessly. Though, I couldn't setup the Dovecot Antispam plugin to train SpamAssassin when I move mails to the Junk folder. I installed the plugin from FreeBSD ports and followed the official documentation [1] and the man page [2] without any success.

Permissions with mailman
by Niklas Lemcke - 林樂寬 15 Jul '14

Hi, I'm running a Mailserver, and recently also a Mailinglist. I'm sporting # dovecot --version 2.1.7 on a debian stable machine with postfix & mailman. Everything works fine, except that no archive is being created (here an excerpt from my log): Jul 2 15:29:39 blade01 postfix/qmgr[5217]: B30BCE1F52: from=<list(a)mail.myserver.com>, size=802, nrcpt=1 (queue active) Jul 2 15:29:39 blade01 dovecot: lda(list): Error: user list: Initialization failed: Initializing mail storage from mail_location setting failed: mkdir(/var/mail/vmail//list/mail) failed: Permission denied (euid=38(list) egid=38(list) missing +w perm: /var/mail/vmail/, we're not in group 5000(vmail), dir owned by 5000:5000 mode=0775) Jul 2 15:29:39 blade01 dovecot: lda(list): Fatal: Invalid user settings.

Now: $ groups list list : list vmail and the permissions are 775, but it's still complaining about "missing +w perm". What is it referring to with "we're not in group 5000"? Thanks for any help! -- Niklas - 林樂寬

by CJ Keist 15 Jul '14

All, Just move our mail servers over to a new mail server running postfix 2.11.1 and dovecot 2.2.13 and getting the subject line errors in my /var/adm/files. People are complaining of loosing their connections to the mail server. I've been able to google this error but haven't found fix for this yet.

Changed IMAP MOVE behavior in Dovecot 2.2.x
by Iavor Stoev 15 Jul '14

15 Jul '14

Hello, After the migration to Dovecot 2.2.13 from Dovecot 2.1.17, I noticed a changed behavior when I move a message from one folder to another. I use Thunderbird with: Account Settings -> Server Settings -> When I delete a message: Just mark it as deleted. I use Thunderbird 24.6.0 with IMAP. With Dovecot 2.1.x when I move a message, the message appears in the new folder and is marked for deletion in the original folder (which gives me an easy option to undo the action if I made a mistake until I choose to Compact/Purge the folder). With Dovecot 2.2.x when I move the a message it is marked for deletion and is AUTO Compacted/Purged immediately. Is there a way to achieve the 2.1.x behavior with Dovecot 2.2.x? Thank you Iavor

Integrity check of mailboxes before dsync
by Murray Trainer 15 Jul '14

15 Jul '14

Hi All, I am migrating a large number of Dovecot mailboxes - some of them are quite old. I hit an issue yesterday with a corrupt file (index?) that was preventing the mailbox from being synced properly As soon as I removed the file the dsync worked. Is there a way to check the integrity of each mailbox / indexes before I dsync it? Thanks Murray

director / main instance
by Will Yardley 15 Jul '14

15 Jul '14

I have directors and backend servers running on the same systems (x3). To be able to run doveadm foo with a minimum of fuss (without having to list socket paths explicitly), should it be the director that's the "default"? If so, is it safe to symlink '/var/run/dovecot' to '/var/run/dovecot-director', or should I just make the director's base path /var/run/dovecot directly? in dovecot-director.conf, I have: service doveadm { inet_listener { port = 8889 } } local 192.168.x.0/24 { doveadm_password = Foo } doveadm_proxy_port = 8888 and in dovecot-main.conf, I have: service doveadm { inet_listener { port = 8888 } } local 192.168.x.0/24 { doveadm_password = Foo } protocol doveadm { auth_socket_path = director-userdb } Is this correct (and is there anything unneeded / redundant there)? # dovecot instance list path name last used running /var/run/dovecot-director director 2014-07-14 20:36:49 yes /var/run/dovecot-main main 2014-07-14 20:36:49 yes # dovecot director status mail server ip vhosts users 192.168.x.xx 100 2 192.168.x.xx 100 0 192.168.x.xx 100 0

Transition from one server to another.
by Anders Wegge Keller 15 Jul '14

15 Jul '14

A frind of mine and I are running a dedicated server, that among other things host mail for ourselves and friends and families. All in all about 15 different domains with 35-40 users. The machine in question is old, so we are doing a slow transition from the old server to the new one. So far, we've managed to move web hosts seamlessly. Due to the technical capabilities at some of the user base, it would be nice to get to a setup, where we can move individual users imaps from the old server to the new one, as we get the time to visit them. I have an idea how such a transition could go: 1. Upgrade the old dovecot 1.2.15 to 2.1.whateveritis from debian squeeze backports. 2. Set dsync up to replicate mails from the old server to the new server. I know that 2.2 is recommended, but with a limited amount of user, I'm willing to take a performance hit. 3. Migrate my parents &c to use the new server. 4. When all users have been moved on to using the new server, upgrade MX records for the domain to point at the new server. 5. When all MX records are updated, decalre success. Is this feasible, and what would the risks be. For instance, during step 4, mails are bound to arrive at bothe the old and new server for some time. Will this cause problems? Is there a simpler solution to the problem? -- /Wegge Leder efter redundant peering af dk.*,linux.debian.*

Have you tried: 10-master.conf service imap { drop_priv_before_exec=yes } as suggested by the error?

protocol specific AuthDatabase Queries
by claus 14 Jul '14

14 Jul '14

Hi, i have to configure different sql-queries for protocol lmtp, another for protocol smtp and one query for other protocols. I have configured in "/etc/dovecot/conf.d/auth-sql.conf.ext" one entry for all protocols and 2 protocol specific entries: protocol lmtp { passdb { driver = sql args = /etc/dovecot/dovecot-lmtp-sql.conf.ext } } protocol smtp { passdb { driver = sql args = /etc/dovecot/dovecot-smtp-sql.conf.ext } } passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } is this correct or do i have to configure all possible protocols seperately? First i had a working configuration for all protocols except for lmtp (but now i need additionally a special query for smtp): protocol !lmtp { .. } protocol lmtp { .. } Can you tell me whats the prefered configuration? Thanks Claus

doveadm dump ignores .pvt
by Thomas Herrmann 14 Jul '14

14 Jul '14

While debugging a different problem, I used "doveadm dump" to show information about a maildir folder; it happily reported values from dovecot.index and dovecot.index.log (confirmed by strace): [...] messages count ........... = 978 seen messages count ...... = 967 [...] However, mail clients reported different values, I guess because the Seen flags were actually stored in the dovecot.index.pvt.log files. Is this a known problem or a result of my (maybe unsupported?) setup? My public maildir folder contains only links to mailboxes of the private maildir of the mail admin, i.e.: /home/vmail/public/.Info -> ../adwin.de/mail-admin/Maildir/.Info namespace { list = children location = maildir:/home/vmail/public:INDEXPVT=/home/vmail/adwin.de/%n/public prefix = ADwin/ separator = / subscriptions = no type = public } My setups leads to .pvt-files in the public namespace, could this be a problem? http://wiki2.dovecot.org/SharedMailboxes/Symlinks explicitly states that symlinking _should_ work. Using version 2.2.13 (debian packages). Regards, Thomas

Flags in public folders disappear when more than 25 flags are used
by Thomas Herrmann 14 Jul '14

14 Jul '14

Hello, I have been using flags in public folders for quite a while with no problems. Once the flags were added to all clients (Thunderbird), they were visible and synchronized properly. Now I have added some new flags, and in the dovecot-keywords files I see that I am now using more than 25 flags (in which case they are not stored using an additional letter in the filename). Now I see that newly added flags are only visible in the client for a short time and then suddenly disappear. How can I debug this, or what may be a reason for this?

High user number tune
by Edwardo Garcia 13 Jul '14

13 Jul '14

Halo, This might seem like another indirect thread. I Monday started new job, first task must replace courier. The job use POP3. and IMAP only for webmail, but must server support 4K POP3 at one times. I see from similar thread current settings not adequate , we will use TLS and if wiki read right Iprotocol So am close in think that need ? service pop3-login { process_limit = 4096 } service pop3 { process_limit = 4096 } service imap-login { process_limit = 2048 } service imap { process_limit = 2048 } then we have service managesieve { process_limit = 1024 } is that all we need change? I see in other thread someone says service anvil but I can not find out about it, does need change as well ? Why is it so complicated to change to let more user on, most other change one setting, dovecot want dozen :(

Pigeonhole sieve misfile
by Patrick Domack 13 Jul '14

13 Jul '14

I'm having an issue with sieve putting some emails into the spam folder, that should not be matching the spam rule. I tried looking but can't seem to find a debug option. Is there any way I can get a log of what the sieve rule path that matches so I can locate the misfiring rule? or maybe something else that is going on. I already checked the dovecot sieve log file, and there is nothing in there.

macros
by Arkadiusz Miśkiewicz 13 Jul '14

13 Jul '14

Does dovecot support any form of macros? I would like to share configuration file between several servers. Configs are different only in tiny aspects. Somethine like: dovecot-server.conf (different on each server): %define ID 55 %define SOMETHING SELECT FROM * WHERE something %define MECHANISMS digest-md5 dovecot-main.conf (common, shared config) !include dovecot-server.conf user_query = ${SOMETHING} AND id=${ID} auth_mechanisms = plain login ${MECHANISMS} etc -- Arkadiusz Miśkiewicz, arekm / maven.pl

Replication on dovecot 2.0
by Tom Barber(Alabs) 11 Jul '14

11 Jul '14

Hi Guys I'm running an Ubuntu 12.04 LTS server and not being particually inclined to upgrade I'm wondering what options I have for replication as it appears to be running dovecot 2.0.19. I saw the wiki page about replication and whilst it says you should use 2.2+ it doesn't say what the minimum requirements are, so I tried doing what it says but I get: Fatal: Plugin 'replication' not found from directory /usr/lib/dovecot/modules Any ideas or tips. Thanks Tom

1.2.4 disk full errors
by Iain Hallam 11 Jul '14

11 Jul '14

Hi. A user on a rather old mail system we have filled their disk space, and Dovecot has started to give lots of errors in the logs about "Expunged message reappeared" and "Duplicate file entry". The user can only see a few new messages, not the 33,551 in their inbox. In the TODO file in the current source code[1], Timo notes that (line 147): maildir: out-of-disk-space failures apparently cause all kinds of problems, e.g. "Expunged message reappeared", "Duplicate file entry"? [1] http://hg.dovecot.org/dovecot-2.2/file/c55c660d6e9d/TODO Does anyone know what's happening with Dovecot here and how to recover so that this user can see mail again? Unforuntately we're on a very old version, 1.2.4. Though there is a plan for migrating to a newer platform, I need to get this user accessing email again rather more urgently. Thanks, Iain Hallam.

Trigger for using an sqlite dictionary for quota
by David Anderson 10 Jul '14

10 Jul '14

Hi, I'm using Dovecot 2.0.9, and was trying to set up a dictionary process to use an sqlite database for quota management. The wiki page has examples for MySQL and PostgreSQL: http://wiki2.dovecot.org/Quota/Dict For sqlite, a trigger needs to be created to get it to work. But I was not sufficiently skilled in sqlite to adapt the PostgreSQL trigger (given on the above URL) for use. Nor did Googling find any example of anyone else who had done it. Does anyone here have an example, or the ability? (Through Googling I found an example trigger for using sqlite with expiries - but I was looking at quotas).

HIGHESTMODSEQ tracking
by Kostya Vasilyev 10 Jul '14

10 Jul '14

Hello, I'd like to follow up on someone else's old thread: http://dovecot.org/list/dovecot/2012-April/082624.html I understand that Dovecot (that 2012 discussion was about version 2.0.18) can return "HIGHESTMODSEQ 1" upon SELECT if persistent modseq tracking was never enabled for a mailbox. I'd like to get a clarification on how to enable proper persistent modseq tracking. Per RFC 4551, "A client supporting CONDSTORE.... indicates its willingness to receive mod-sequence updates... by issuing:" SELECT mailbox (CONDSTORE) STATUS (... HIGHESTMODSEQ ...) ... others ... It seems that Dovecot 2.1.7 (Debian 7.5) enables persistent modseq tracking after one of the above two commands (and maybe others). So far so good. So my questions are: 1 - Is this (enabling persistent modseq) also the case for all Dovecot versions prior to 2.1.7 that advertise CONDSTORE? There must be people running older versions out there, older than 2.1.7. If not, how can I branch my logic to not use HIGHESTMODSEQ, given that Dovecot doesn't appear to return any version info via its greeting or via the ID command? 2 - Is persistent modseq tracking (assuming it's been enabled) available for all types of backend mailbox formats that Dovecot might be using? To be more specific, can it ever be the case that Dovecot appears to enable modseq tracking, returning nice looking HIGHESTMODSEQ values from SELECT / STATUS, but the actual values get reset or not get updated because they're not properly persistent? I'm excluding changes to UIDVALIDITY here, obviously when that changes, the entire mailbox state must be assumed to have changed completely. 3 - I guess the change to return NOMOSEQ instead of "1" for mailboxes with modseq tracking disabled, as mentioned in that discussion from 2012, never happened? At least on the 2.1 branch? Thanks, -- K

Multiple email clients not in sync
by Marc Perkel 09 Jul '14

09 Jul '14

Hello everyone, I'm not sure if this is an issue with dovecot or my various email clients, or my settings. I'm running 2.2.13 and I have Thunderbird on my desktop and K@mail on my android phone. In theory if I delete email on one it should delete it on the other. It does delete it on the server - but the other client isn't always "aware" of it. Same thing sometimes with read messages. I read on one device but the other didn't know it's read unless I shut down and restart the app. Not knowing the details of how this all works I'm assuming there is some form of notification that goes on in the background so as to let other clients know what other clients do so they can sync up. And that where my setup isn't working consistently. Maybe my expectations are just too high? Maybe I don't have things set up correctly? What am I missing? Thanks in advance.

Problem with virtual mailbox when using K9 mail (android)
by Henrik Kjölhede 08 Jul '14

08 Jul '14

Hi! I've managed to setup a virtual mailbox that shows all unread or flagged mail from a selection of IMAP folders. This works great with Roundcube, which I use as webmail client. However, using K9 mail on my android phone, a mail that is opened seems to be immediately marked as read, and any flagging I do doesn't take. Presumably this is because it can't be reached any longer in the virtual folder. I tried adding the recent flag to the virtual search line, but that doesn't make any difference. I haven't been able to locate any information about anyone else experiencing this problem, so I was hoping that someone here could help. I realise that this is not exactly a "dovecot problem", but perhaps someone here has found a solution that they are willing to share. The search line in dovecot-virtual is currently "OR RECENT (OR UNSEEN FLAGGED). Regards

Limit confusion
by Micah Anderson 08 Jul '14

08 Jul '14

Hi, On one of my dovecot servers, i've got a limit problem... and I'm a little confused about which knobs I should adjust to solve it. I've been getting both of these: Error: net_connect_unix(imap) failed: Resource temporarily unavailable - http://wiki2.dovecot.org/SocketUnavailableess This one caused me to go read that wiki page, but none of those seem to apply to me: . i'm running 2.2.9 . i dont have service imap { client_limit }, although I do have service auth ( client_limit = 1024 } . my dovecot/auth process shows: dovecot/auth [91 wait, 0 passdb, 0 userdb] . it doesn't appear the master process is using very much cpu (in fact the system is mostly low load in general) .

Dovecot ignores existing mailboxes and creates its own
by Martin Vegter 08 Jul '14

08 Jul '14

Hello, I have Postfix with Maildir format. User's emails are being delivered into $HOME/mail/inbox Apart from ~/mail/inbox, there are the usual folders: $HOME/mail/archive $HOME/mail/drafts $HOME/mail/inbox $HOME/mail/trash Now I have installed dovecot, and set mail_location = maildir:~/mail:LAYOUT=fs additionally, I have defined mailboxes as follows: namespace inbox { mailbox drafts { special_use = \Drafts } mailbox sent { special_use = \Sent } mailbox trash { special_use = \Trash } } The problem I am having is following: 1) dovecot ignores the folders (drafts, sent, trash) and creates its own folders begining with capiotal letter: Drafts Sent Trash 2) dovecot ignores ~/mail/inbox and instead creates ~/mail/cur ~/mail/new ~/mail/tmp can somebody please advise how to tell dovecot, to use my existing folder structure, ie: ~/mail/inbox/{cur,new,tmp} ~/mail/drafts/{cur,new,tmp} ~/mail/sent/{cur,new,tmp} ~/mail/trash/{cur,new,tmp} any advice would be much appreciated thanks, Martin

Dovecot not changing SSL key and certificate as in config file
by Mitchell McMillan 08 Jul '14

08 Jul '14

I am trying to use my (decrypted) SSL key and certificate in Dovecot. I have changed /etc/dovecot/conf.d/10-ssl.conf like so: ssl_cert = </etc/ssl/private/ssl-chain-mail-mydomain.com.pem ssl_key = </etc/ssl/private/ssl-key-decrypted-mail-mydomain.com.key However, after running service dovecot restart, dovecot -n still says that the files /etc/dovecot/dovecot.pem and /etc/dovecot/private/dovecot.pem are being used. I am using dovecot 2.2.9, any help would be greatly appreciated.

doveadm quota recalc -A
by ML mail 08 Jul '14

08 Jul '14

Hello, It looks like my iteration SQL query (iterate_query) does not work as when I try to run "doveadm quota recalc -A" I get the following error: $ sudo -u vmail doveadm quota recalc -A doveadm(nobody): Error: user nobody: Mail access for users with UID 65534 not permitted (see first_valid_uid in config file, uid from userdb lookup). doveadm(nobody): Error: User init failed My iterate_query is quite simple: iterate_query = SELECT username FROM mailbox So from the output I really don't understand why it looks up the user "nobody". I don't have any user "nobody" in my mailbox SQL table. Anyone has an idea? Regards ML

Redis sentinel support in dict
by Lazy 08 Jul '14

08 Jul '14

Redis sentinel ( http://redis.io/topics/sentinel ) is a service that monitors and manages redis master slave replication. Using sentinel you can easily create a redis ha cluster. You can connect to a sentiniel and subscribe to certain events then in case of an failover update the redis address to new master etc. I think this is better suited to be used with dict proxy. Do You think it can be implemented without changes to dovecot core ? -- Michal Grzedzicki

dovecot 2.2.13 core dump (signal 11)
by Tom Lieuallen 08 Jul '14

We just upgraded from 2.1.16 to 2.2.13. One user is experiencing problems when using the shared namespace. Specifically it happens when opening/reading a message and when deleting messages. These functions work for other users. So far, this appears to be only affecting one user.

Multiple Instances with Director
by Cassidy Larson 08 Jul '14

08 Jul '14

I have four front end servers with two backend servers. Each front end server has three instances for different mail hosts (individual SSL certs, etc). I'm looking at adding a fourth instance on each front end server for the director process. Currently we just return the backend server ip via SQL and use the old master username/password to proxy the inbound POP/IMAP sessions to the correct backend server. The plan is for each instance to have connect to the same list of director_servers (one from each front end server). What's the trick to separate a director instance into its own setup and having multiple instances/servers connect to that director? Currently I have on my proxy instance: director_servers = 10.128.1.42:9090 (this is the inet_listener from the director instance) service director { unix_listener login/director { mode = 0666 } fifo_listener login/proxy-notify { mode = 0600 user = $default_login_user } unix_listener director-userdb { mode = 0600 } } And I get in logs: director: Fatal: No inet_listeners defined for director service (for standalone keep director_servers empty) Do I need an inet_listener on the front end instance if I want to forward all director queries to the director_servers list? Or is there some other trick to get a proxy front end to talk to a separate director instance(s)? Thanks, Cassidy

question on lmtp logged message
by Leonardo Rodrigues 07 Jul '14

07 Jul '14

Hi, I have dovecot running for IMAP4/POP3 and also local delivery through LMTP. It's working just fine, absolutely no problem on that, setup is fine. Anyway, sometimes LMTP seems to not be able to deliver some messages and keep them on postfixqueue. And on the next or third try, the message gets delivered successfully. The logged message, however, is not helping me identify what is happening.Example: (error - message was expunged) Jun 25 11:49:39 correio postfix/lmtp[21835]: ADB0A1AC05108: to=<vanilson.parreira(a)domain.com.br>, relay=correio.domain.com.br[private/dovecot-lmtp], conn_use=6, delay=13, delays=0.07/0/0/13, dsn=4.2.0, status=deferred (host correio.domain.com.br[private/dovecot-lmtp] said: 451 4.2.0 <vanilson.parreira(a)domain.com.br> Message was expunged (received-date) (in reply to end of DATA command)) (successfull delivery) Jun 25 12:34:42 correio postfix/lmtp[6411]: ADB0A1AC05108: to=<vanilson.parreira(a)domain.com.br>, relay=correio.domain.com.br[private/dovecot-lmtp], delay=2716, delays=2714/0/0/2.3, dsn=2.0.0, status=sent (250 2.0.0 <vanilson.parreira(a)domain.com.br> U7pOLAHsqlPvMgAAHvf8vg Saved) During these two log entries, absolutely nothing was changed, no configuration, absolutely nothing. Everything is local, i mean, no NFS involved. So, finally, question is: what does the 'message was expunged' message given from LMTP means ??? This is happening quite often but, as i mentionted, sooner or later all messages are getting delivered. It's working despite the delay this is causing.

dbox alternate storage and samba
by Francesco 07 Jul '14

07 Jul '14

Hello everyone, i was just wondering if it's possible to use a samba share as an alternate storage for dbox format. I tried creating a samba share, but when i try to move the email to the alternate storage using doveadm altmove, no errors are printed but no mails are moved. Everything works if the alternate storage is simply another directory on the server hard drive. am i mssing something? thanks in advance.

rmdir() EBUSY warnings on 2.2.12
by Giel van Schijndel 07 Jul '14

07 Jul '14

Hi, I'm getting a lot of syslog spam on FreeBSD 10 from nfs_flush_file_handle_cache_dir where, apparently it tries to rmdir() the mountpoint of my mail storage. > Jul 4 00:04:44 mailhost dovecot: imap(user(a)example.com): Error: nfs_flush_file_handle_cache_dir: rmdir(/var/mail/vhosts/example.com) failed: Device busy We're using ZFS and have /var, /var/mail, /var/mail/vhosts, /var/mail/vhosts/example.com and /var/mail/vhosts/example.com/user as separate ZFS datasets (to enable per-user and per-domain snapshotting). So apart from NFS flushing being unnecessary (ZFS != NFS) I'm not really sure why using rmdir() for another directory than the Maildir specified in mail_location is a good idea. I.e. given that Maildirs shouldn't ever be emtpy (cur,new,tmp) anyway. -- Met vriendelijke groet, With kind regards, Giel van Schijndel -- > A programmer started to cuss > Because getting to sleep was a fuss > As he lay there in bed Looping 'round in his head > was: while(!asleep()) sheep++; > -- piercings -- http://bash.org/?845468

by wuwei 07 Jul '14

07 Jul '14

hello everybody: I'm using dovecot with pigeonhole sieve Plugin.everything goes well.but when i use vacation module,i found a problem: I write a sieve with a vacation module in, and put it to the sieve location ,used *PUTSCRIPT* comand with *ManageSieve* and *set it ACTIVE*.It's work!I use A email send mail to him and receive an auto-reply.then ,I modify the sieve only change the days num from 7 to 1.Then I use B email send mail to him and receive an auto-reply too. The next day,I send two mails too.But only B receive the auto-reply.I thought that I would receive two mails too. so i think that A email's data in sieve maybe still 7 days.Then I restart the dovecot,but the problem still exsit. Is anyone know how to refresh the data or is their anyother way to solve the problem? thank you! -- View this message in context: http://dovecot.2317879.n4.nabble.com/help-how-to-refresh-pigeonhole-sieve-v… Sent from the Dovecot mailing list archive at Nabble.com.

If like from Nick Edwards suggested a imapproxy is used it will. imapproxy is keeping the connection open. doveadm who will give you a list of all actual logged in users. Without imapproxy you are right: Every page reload will cause a login and a logoff. I get some webmail users by "accident". To get an overview how many users used roudcube within a period check the database table users/last_login. Andreas

Disable user login for a few seconds ?
by Florent B 05 Jul '14

05 Jul '14

Hi all, I need to move e-mail files of my users from one file system to another. I use a MySQL backend on Dovecot 2.1. How can I do to disable temporary an account while moving files ? I have an "active" bit in my DB, but if I set it to 0, my MX servers are bouncing mails. How can I do to disable temporary an account ? In fact, I need dovecot not to do any change on files... I think I could change account password for a while, and reset it after migration, but it will disturb connected users. Maybe I could chmod 0 files on my old file system during migration ? How Dovecot will act ? Thank you :) Flo

Shared Mailbox + LDAP Easy with this script
by Allan Cassaro 05 Jul '14

05 Jul '14

Hello guys, After some hours fighting with shared mailbox, I finally understand how it works - and, realy, I can't believe how easy it is! So, to help others like me and to improve the shared mailbox with Dovecot this script does all the "hard work". I don't know if this group permit attachments, so, let's the link: https://sites.google.com/site/allancassaro/mkshared.tar.gz Enjoy! ===== From README file ===== This is a simple code to help with Dovecot Public Shared Mailbox function. Just configure a public shared mailbox with ACLs, change the configuration file and run this program. How it works: 1) The program connect to the LDAP server and fetch groups from it (with ldap filter) 2) With groups, it fetches the members and owners (or any attribute you want); 3) It will walk into the "shared folder" folder base directory and: 3.1) Rename any directory that was renamed in LDAP (based on entryUUID ldap attribute); 3.2) Create diretories and skeletion (new, cur and tmp) of any group that exists in LDAP; 3.3) Optionaly, remove any "orphan" directory (wihtout a ldap entrey); Example: dn: cn=Everyone,ou=Shared_Mailbox, dc=example,dc=com objectClass: labeledURIObject objectClass: top objectClass: groupOfURLs cn: Everyone labeledURI: ldap:///ou=Users,dc=example,dc=com?uid?one?(objectClass=person) member: uid=user2,ou=users,dc=example,dc=com member: uid=user3,ou=users,dc=example,dc=com member: uid=user1,ou=users,dc=example,dc=com member: uid=user.surname,ou=users,dc=example,dc=com owner: uid=user4,ou=Users,dc=example,dc=com This will create a folder tree like this: /path/toshared/.Everyone /path/toshared/.Everyone/new /path/toshared/.Everyone/cur /path/toshared/.Everyone/tmp With permission file (/path/toshared/.Everyone/dovecot-acl): user=user1 lr ... user=user.surname lr user=user4 lrwstipekxa Hope this helps you!

Shared folders not listed by IMAP

[Dovecot] dovecot: disable ssl compression
by Andreas Schulze 04 Jul '14

04 Jul '14

Hello, Our "it-security" department asked me about Qualys warnings like -> SSL/TLS Compression Algorithm Information Leakage Vulnerability As far as I learned it's compression inside ssl. postfix-2.11 knows 'tls_ssl_options = no_compression' ( see http://www.postfix.org/postconf.5.html#tls_ssl_options ) is the something comparable in dovecot too? Looks like most extensions in ssl exist only to be disabled :-/ Thanks Andreas

mixing Maildir and mdbox
by gustavo panizzo <gfa> 04 Jul '14

04 Jul '14

Hello i'm in the process to architect a new email system. i plan to use dovecot 2.2.9 (debian's wheezy). i would like to use maildir for 2 folders on each account (spam and no-spam) and the rest of the folders stored on mdbox. this should be opaque to my users. the reason for this, is i want to be able to train my anti-spam tools, but they read maildir or mbox, they don't read mdbox or dbox. but i want the other folders as mdbox (performance, backups, alternate storage) is there any way?, i prefer if is configurable in advance for all accounts but i could live with something that is done after account is created thanks! -- 1AE0 322E B8F7 4717 BDEA BF1D 44BB 1BA7 9F6C 6333

stripping extension from domain name
by Jerry 03 Jul '14

03 Jul '14

Thu, 3 Jul 2014 06:29:06 -0400 I know that the "%d" parameter is for the domain. Is there any way to use just the domain name sans its extension. EXAMPLE: example.com ==> example Also, I have a lot of logging going on in my dovecot log file. I want to limit it to just the barest amount, such as indicting what mail box mail was delivered to. Authentication errors, etcetera should only be shown if an error occurs. Is this possible? Thanks! -- Jerry

ACL configuration migration from Dovecot 2.1.17 to 2.2.13
by Iavor Stoev 03 Jul '14

03 Jul '14

Hello, I'm preparing migration to the latest Dovecot version 2.2.13 from the previous stable branch 2.1.17 which is deployed on my servers. With version 2.1.17 I use global acl dir to prevent all mail users to delete their INBOX.Junk Mail folder, which is part from our spam protection system. My current config is: cat /etc/dovecot/acls/INBOX.Junk\ Mail owner lrwstiae With version 2.2.13, the global acl dir support is disabled (with the above config, the imap server shows no folders at all) so I must use global acl file. The problem is that the "INBOX.Junk Mail" folder contains space character and I tried to escape it with "",'',/ and enclose the whole name with "" & '' without success. If I change the acl config to INBOX.Mail it works OK. The syntax of my global acl file is: cat /etc/dovecot/acls INBOX.Junk Mail owner lrwstiae The error is: Error: Global ACL file /etc/dovecot/acls line 1: Unknown ID 'Mail' Please advise Iavor Stoev Project Manager // Head of System & Network Administration Department

Bug/feature: mail fs pollution on IMAP select namespace/{non-existent}
by Peter Benko 03 Jul '14

03 Jul '14

Hi all, I have noticed a strange behavior with dovecot (tested with 2.2.13). I use shared folders to share mailboxes between users. I have a namespace called "Accounts" that hosts the shared folder for the users (prefix Accounts/%%n/). However, When I issue an IMAP select command on a random non-existent mailbox name under "Accounts", dovecot auto-creates it and pollutes my mail root directory: Python test code snippet: imapConn=imaplib.IMAP4_SSL(serverIP, serverPort) imapConn.login(serverLogin, serverPass) print imapConn.select("Accounts/NonExistentMailbox") imapConn.logout() Resulting in this: drwxr-x--- 1 vmail vmail 4096 Jun 12 10:00 _attachments_ >>> drwx------ 1 vmail vmail 4096 Jun 24 14:27 NonExistentMailbox <<< drwxr-x--- 1 vmail vmail 4096 Jun 24 00:54 user1 drwxr-x--- 1 vmail vmail 4096 Jun 24 01:24 user2 ... -rwxr-x--- 1 vmail vmail 72 Jun 24 14:27 shared-mailboxes.db ls -l NonExistentMailbox/ -rw------- 1 vmail vmail 0 Jun 24 14:27 dovecot-acl-list drwx------ 1 vmail vmail 4096 Jun 24 14:27 mailboxes <<< (empty) I attached a debug log and and my sanitized dovecot config. Please help! Is this a bug or a feature? I assume it might even cause more serious problems e.g., if I would select "Accounts/_attachments_" or something similar... I noticed this behavior with the latest Thunderbird client when I tried to subscribe to shared folders and it started to pollute my mail dirs (which signals that Thunderbird might be also buggy as it should not select non-existent folders under "Accounts"). I just reproduced it for simplicity with the above python script.

Dsync replication one-way
by Muriel 03 Jul '14

03 Jul '14

Hi all, I know that I can do a backup using doveadm: doveadm backup -u user ssh backup.server doveadm dsync-server -u user But it's possible to use replicator service to do the same job? Or dsync with replicator can only be used in a two-way environment? Thanks, Muriel

[Dovecot] zlib maildir reindex broken
by Richard Platel 03 Jul '14

03 Jul '14

I posted to the list about this a while ago but never got a response, I have a bit more information now. Dovecot 2.2.12 and other 2.2 versions are broken when using zlib and maildir. If messages are re-indexed, the INTERNALDATE of all messages is set to the time the re-index is done. The problem seems to be in src/plugins/zlib/zlib-plugin.c in the function zlib_mail_cache_open. During a reindex maildir_mail_get_received_date() does an i_stream_stat on the the i_stream_seekable stream created in zlib_mail_cache_open, but this istream does not know about the original maildir message file and always returns the current time for the file's stat times. This is also broken on initial index, but if mail is indexed when it's received (ours isn't) it coincidentally gets the right time.

BUG: segfault in auth when user listed multiple times in LDAP

Hi, I think I found a bug in the auth module. It can be triggered when the userdb is in LDAP and an user is found multiple times in LDAP.

Bug in quota_get_status
by Franz Knipp 03 Jul '14

03 Jul '14

Hi, the configuration option lmtp_rcpt_check_quota = yes didn't work, so I traced down the problem: quota_get_status (quota_storage.c:89) calls quota_test_alloc (quota.c:1352) with size = 0 bytes, which leads always to a FALSE result in quota_is_over (quota.c:1305). I've fixed the function quota_is_over by considering ctx->bytes_over and ctx->count_over. See the included patch. Kind regards, Franz -- Franz Knipp, +43 664 3980169 qnipp GmbH, Hauptstraße 54, 7064 Oslip, Österreich http://qnipp.com http://qnipp.com/qnipp.vcf

Mailboxes are in Maildir format. Any good backup tips? Had success with version control?
by deoren 03 Jul '14

03 Jul '14

I'm still pretty new to running a mail server, but one thing I've come to appreciate over the years is a good backup strategy. Since I have always run my own servers for practice and for personal use I don't have access to Enterprise backup solutions. Because of that I usually just fall back to scripts and tarballs and offload the content on a regular basis. Right now I'm using LVM snapshots + tarballs for daily backups, but I'd like to get better coverage for incremental changes that occur throughout the day. The size of existing content is low, but (small) changes are frequent. I went with Maildir format because based on my reading it is referred to as time tested and corruption resistant. Because individual emails are stored as separate files this also leads me to believe that a version control system (Git, SVN) would allow for easy point in time restores. I'm also going to research the GNU tar utility's support for incremental archives as that sounds promising. Suggestions and warnings are most welcome. Thanks!

How do you configure an iterate_query SQL lookup for the doveadm director? I tried: service director { userdb { ... } } but userdb is not a valid stanza for director. I do not have a default userdb stanza, all my userdb definitions are specified in service imap/lda/lmtp blocks. Thanks. G H

[Dovecot] TLS/SSL for Win8 & Outlook
by Sebastian Goodrick 02 Jul '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello I recently upgraded to dovecot 2.1.7 (as supplied with Debian Weezy).

[Dovecot] lazy_expunge and shared folders
by Florian 02 Jul '14

02 Jul '14

Hi, since migration to Dovecot 2.2 I have troubles with lazy_expunge as soon as a user shares a folder. The user the folder is shared to cannot login anymore, dovecot logs Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/' - When no folder is shared lazy_expunge is working fine, deleted mails are moved to the expunged namespace and can be recovered without any problems. - Sharing folders works as long as I disable lazy_expunge. I have used the config (with minor changes) with dovecot 2.0 for years without any problem. Switching to dovecot 2.2.10 (atrps repository) or 2.2.12 (dovecot enterprise repo) lazy_expunge and acl do not work together anymore. Is it a bug, a known limitation or is something wrong with my config? Any hints are welcome.

Direct groups of users to pairs of backend mailstores?
by Murray Trainer 02 Jul '14

02 Jul '14

Hi All, We are using Dovecot in a Director setup with two director proxies, six backend mailstores, mailbox storage in NFS, and user accounts stored in LDAP. Currently we have five NFS filesystems on EMC VNX storage which are all mounted on each of the six backend mailstores. At the moment all users could be directed to any of the six mailstores. We have a group of users with very large mailboxes we want to put on separate cheaper Backblaze NFS storage. Because this will be less reliable than our VNX storage we want to be able to direct this group of users to a new pair of backend mailstores that only have the Backblaze NFS mounts. This would isolate the rest of the users isolation from problems with the Backblaze NFS servers. I have read the Dovecot documentation which indicates it is possible to direct users always to a single backend server. Can Dovecot direct users to a pair or more of backend mailstores - ie a subset or another set of mailstores. If not it would be a great enhancement which would allow more scalability, flexibility and redundancy. Thanks Murray

Managing users and home dirs
by deano-dovecot＠areyes.com 02 Jul '14

02 Jul '14

For those of you using virtual users, and SQL, how are you managing your users and their home dirs ? That is, what process do you use for adding/deleting users, creating their home dirs etc ? I suppose it's easy enough to do manually, inserting rows in the database, creating dirs, chown/chmod yada yada, but there must be a better way to do it ... If you're doing dovecot replication then it gets even more cumbersome, having to duplicate the effort in two places (and make sure it's correct). I have a nice test setup using Percona XtraDB Clustering in a 3-node cluster which works swimmingly, albeit in VMs only at the moment. A master DB node and two dovecot nodes. Dovecot replication is up and running nicely too, and I almost have all the communications going over ipsec tunnels, so it will be nice and secure. I'm thinking of something like a cronjob with two tasks, the first would periodically scan the home dirs and compare the users to what's in the database. When it finds a new userdir (plus a file labeled PASSWD) the script would add the user to the database, create the Maildir and whatever else, then delete the PASSWD file. DB replication will push that to the other nodes. The second task is scanning the user database and comparing to the home dirs - basically opposite of the first cronjob. When it finds a user in the DB that doesn't have a home dir, it would create it and whatever else is needed. This way, to add a user one would just create a PASSWD file in /var/mail/domain.com/newusername/PASSWD on either of the dovecot replication partner systems. The first cronjob task would discover the newusername dir, create the user in the DB, create the Maildir, chown/chmod etc. and delete the PASSWD file, so it's ready to go on that system. DB replication pushes the user table to the other nodes. The second task on the other dovecot system will discover a new user in the DB that doesn't have a home dir, and do its thing to create it all. So the whole create-a-new-user process becomes something like this on either dovecot system : mkdir -p /var/mail/domain.com/newusername ; echo "changeme" > /var/mail/domain.com/newusername/PASSWD A max of 5 minutes later the user is added to the database, and the home dir/Maildir/etc/etc is created on both dovecot systems.

i need a little advice with dovecot master user

Hello, As a step to migrate to a newer version of dovecot, i've been asked to configure a master user for logging in into mailboxes of a dovecot 1.2. I've followed the instructions from this page: http://wiki1.dovecot.org/Authentication/MasterUsers but appearently something is going wrong. I've turned on the auth verbose and what i get in the log is: 2014-06-30 15:25:03 auth(default): Info: passdb(administrator,127.0.0.1,master): Master user logging in as user(a)domain.tld but the output from a telnet session says: Trying 127.0.0.1...

Login failure with SElinux enforcing + Sqlite user DB
by G H 30 Jun '14

30 Jun '14

I am having a very strange issue with Dovecot + Sqlite + SELinux in enforcing. I am able to log in via IMAPS if SELinux is in permissive, but not able to do so when in enforcing. I do not see any SELinux denials even with dontaudit's enabled. I am running Centos 5 on x86_64 with a customized kernel build and SElinux Strict policy. The log dumps below are in the following order: 1. My syslog output when SElinux is enforcing 2. My mail client's protocol log (using Sylpheed) 3. My syslog output when SElinux is permissive. From the audit log, syscall 2 (from the message "type=SYSCALL ... syscall=2 success=no" appears to be sys_open for x86_64 architectures. syscall 87 is sys_unlink. Why is my mail client getting a SQL error message even though dovecot's auth log reported login success? Is this a sqlite problem instead of a dovecot one? FYI, I am using dovecot-2.2.10 (from ATrpms.net) and sqlite-3.3.6-7 There appears to be several options related to the temporary store on sqlite's documentation, the solution may be to use memory (instead of files) for temporary tables... dovecot: auth-worker(29695): Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_mysql.so dovecot: auth-worker(29695): Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_pgsql.so dovecot: auth-worker(29695): Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so dovecot: auth-worker(29695): Debug: sql(mailadmin,10.0.77.80): query: SELECT password FROM users WHERE username = 'mailadmin' dovecot: auth: Debug: client passdb out: OK 1 user=mailadmin dovecot: auth: Debug: master in: REQUEST 3487432705 29692 1 17d4d0374be5dec51ce20917470caed8 session_pid=29696 request_auth_token dovecot: auth-worker(29695): Debug: sql(mailadmin,10.0.77.80): SELECT username FROM users WHERE username = 'mailadmin' AND view_mail = 't' AND 'imap' = 'imap' dovecot: auth: Debug: master userdb out: USER 3487432705 mailadmin uid=97 gid=12 home=/var/mail/mailadmin auth_token=e0d0ed3080574ab089f1a5302d43110ffa15ec42 dovecot: imap-login: Login: user=<mailadmin>, method=PLAIN, rip=10.0.77.80, lip=10.0.78.223, mpid=29696, TLS, session=<0C+M3A/9OwCsEQFQ> audispd: node=myhost.somewhere type=SYSCALL msg=audit(1404144473.421:46298): arch=c000003e syscall=2 success=no exit=-13 a0=7fff97f77ce0 a1=c2 a2=1a4 a3=0 items=1 ppid=29697 pid=29699 auid=7033 uid=8 gid=12 euid=8 suid=8 fsuid=8 egid=12 sgid=12 fsgid=12 tty=(none) ses=108 comm="sqlite3" exe="/usr/bin/sqlite3" subj=system_u:system_r:dovecot_t:s0 key="access" audispd: node=myhost.somewhere type=CWD msg=audit(1404144473.421:46298): cwd="/var/run/dovecot" audispd: node=myhost.somewhere type=PATH msg=audit(1404144473.421:46298): item=0 name="./sqlite_ZPh8vGq4ia1CCsJ" inode=8192027 dev=fb:02 mode=040755 ouid=0 ogid=97 rdev=00:00 obj=system_u:object_r:dovecot_var_run_t:s0 audispd: node=myhost.somewhere type=EOE msg=audit(1404144473.421:46298): audispd: node=myhost.somewhere type=SYSCALL msg=audit(1404144473.422:46299): arch=c000003e syscall=2 success=no exit=-13 a0=7fff97f77ce0 a1=c2 a2=1a4 a3=0 items=1 ppid=29697 pid=29699 auid=7033 uid=8 gid=12 euid=8 suid=8 fsuid=8 egid=12 sgid=12 fsgid=12 tty=(none) ses=108 comm="sqlite3" exe="/usr/bin/sqlite3" subj=system_u:system_r:dovecot_t:s0 key="access" audispd: node=myhost.somewhere type=CWD msg=audit(1404144473.422:46299): cwd="/var/run/dovecot" audispd: node=myhost.somewhere type=PATH msg=audit(1404144473.422:46299): item=0 name="./sqlite_9i9aIbK0rBuJWFS" inode=8192027 dev=fb:02 mode=040755 ouid=0 ogid=97 rdev=00:00 obj=system_u:object_r:dovecot_var_run_t:s0 ...

Sieve seems to break mailbody during automatic redirection

Hi, I have a strange problem with sieve. After upgrading to 2.2.13 sieve seems to break the mailbody during automatic redirection.

The part of the mail-header looks normal. But as you can see at beginning of the mailbody something inserts the strange character "^M" after each newline. According to Google this is a endline charachter from Windows. And this seems to break some clients (Eg. Lotus Notes). With dovecot version 2.1.x I don't have this problem. Have you any solution for me? Many thanks Urban Loesch

Any issues with dsync between 2.1.7 and 2.2.9 ?
by deano-dovecot＠areyes.com 29 Jun '14

29 Jun '14

My current production system is running dovecot 2.1.7-7ubuntu1 on Ubuntu 13.04, and I'm building a new setup based on Ubuntu 14.04 with dovecot 2.2.9-1ubuntu2.1 - current standard in the repos. I'd like to use replication to get the mailstore from the old system to the new. Are there any caveats or gotchas to be aware of ? Is it possible to make it a one-way replication ? So problems or glitches on the new setup don't propagate to the old production ? Thanks - D.

Procmail to Sieve translation
by Gerhard Wiesinger 28 Jun '14

28 Jun '14

Hello, I'm trying to move from procmail to dovecot sieve. I found the translation script at http://www.dovecot.org/tools/procmail2sieve.pl It works well except the following use cases: * ^From:.*myemail@mydomain.com.* | formail -I"X-Priority: 2 (high)" -I"X-mydomain-com-seen: yes" | $SENDMAIL -oi \ myemail(a)mydomain2.com \ myemail(a)mydomain3.com :0c * ^From:.*myemail@mydomain.com.* ! +1123456789(a)mysmsprovider.com :0c * ^(To|Cc|Bcc):.*myemail@mydomain.com.* ! myemail(a)mydomain2.com myemail(a)mydomain3.com Is there a possibility to support these use cases (can be done manually)? How does forwarding to another domain work at the deliver process? :copy seems not to be supported, right? Thank you. Ciao, Gerhard

Dovecot virtual and SASL with Postfix
by Jerry 28 Jun '14

28 Jun '14

This is my first attempt to set up virtual users and sasl with Postfix. Can I use a regular password file in this format: user:{plain}password user2:{plain}password2 or do I need to use a different format? I have been trying to find an example of a virtual user SASL file, but without any luck. I suck at Googling too. All of the mail will be delivered to :/var/mail/vmail/<domain>/<user> -- Jerry

mixing Maildir and mdbox
by gustavo panizzo <gfa> 28 Jun '14

28 Jun '14

Hello i'm in the process to architect a new email system. i plan to use dovecot 2.2.9 (debian's wheezy). i would like to use maildir for 2 folders on each account (spam and no-spam) and the rest of the folders stored on mdbox. this should be opaque to my users. the reason for this, is i want to be able to train my anti-spam tools, but they read maildir or mbox, they don't read mdbox or dbox. but i want the other folders as mdbox (performance, backups, alternate storage) is there any way?, i prefer if is configurable in advance for all accounts but i could live with something that is done after account is created thanks! PD: please keep me CC'ed as i'm not subscribed to the list -- 1AE0 322E B8F7 4717 BDEA BF1D 44BB 1BA7 9F6C 6333

Just did some more scripting and got a total of 1413 distinct emails (distinct queueids) that suffered from this 'message was expunged' problem on the 36 hours i got the problems. As noted before, not even a single one of these 1413 were nrcpt=1. Problems were from nrcpt=2 or greater. So, whatever this is, it really seems to NOT affect single recipient messages. As you suspected, on those 1413 the very first recipient ALWAYS got a status=sent from dovecot/lmtp. "Message was expunged" never happened on the very first recipient delivery. About the first user (the first delivered message) checking the message right after delivery, i tried to confirm that by the logs. To make things a little easier, i used nrcpt=2 and nrcpt=3 situations, just to avoid posting lots of logs here.

Despite of that, 2nd recipient got the message successfully delivered. But we have also a delay=22 ... maybe lmtp instance had already opened the message BEFORE it was erased by the 1st user ? this delay is high, i know that and, usually, server do NOT suffer from this delays on deliveries. Anyway, during this problem period, queues were pretty large and, thus, load was very high, which i think explains this unusual delays. With these two cases, it really seems that this is somehow related to: - lmtp as delivery agent - multiple recipient messages - first (or previous users in fact) checked and deleted the message before all the recipients got the message delivery About the two parameters, maildir_copy_with_hardlinks and pop3_fast_size_lookups, i'll try to change them one at a time and try to reproduce the problems. Fact is i only had the problem with both set to yes and problems were completly vanished when both were set to no. -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

imap/pop3/lmtp proxy question/problem
by Jogi Hofmüller 25 Jun '14

25 Jun '14

Dear list, We are finally back to our task of migrating from cyrus to dovecot. dovecot mostly does what we want in terms of POP3/IMAP server. Now we are preparing for migration. The plan is to use dovecot as proxy for not-yet migrated accounts. This works wonderfully for IMAP but not for LMTP. Here's what I find in the logs when I try to deliver e-mail to the dovecot lmtp port: Jun 25 19:03:06 klee dovecot: lmtp(5037): Debug: none: root=, index=, indexpvt=, control=, inbox=, alt= Jun 25 19:03:06 klee dovecot: lmtp(5037): Connect from IP-address Jun 25 19:03:06 klee dovecot: lmtp(5037): Debug: user USER: Auth PASS lookup returned temporary failure: reason=Configured passdbs don't support crentials lookups Jun 25 19:03:06 klee dovecot: lmtp(5037): Debug: auth input: reason=Configured passdbs don't support crentials lookups Delivery works fine without proxy (lmtp_proxy = no). What I would need to do is to configure the proxy part so that POP3/IMAP uses the accounts username/password and LMTP uses a special account to deliver e-mail. This is dovecot-ldap.auth (the =proxy=y will be replaced by a field from ldap once the tests work): uris = ldaps://our.ldap.server/ tls = no auth_bind = yes base = dc=mur,dc=at deref = never scope = subtree user_attrs = =home=/srv/vmail/mail/%Lu,=uid=999,=gid=999 user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password,=proxy=y,=host=our.imap.server,=starttls=yes iterate_attrs = uid=user iterate_filter = (objectClass=posixAccount) dovecot -n # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 3.14-1-amd64 x86_64 Debian jessie/sid auth_verbose = yes disable_plaintext_auth = no lmtp_proxy = yes login_greeting = Dovecot is spitze! mail_debug = yes mail_location = maildir:/srv/vmail/mail/%u mail_plugins = acl namespace { hidden = no inbox = no list = children location = maildir:/srv/vmail/mail/%%u:INDEX=/srv/vmail/mail/%u/shared/%%u prefix = shared.%%u. separator = . subscriptions = yes type = shared } namespace inbox { hidden = no ignore_on_failure = no 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 = INBOX. separator = . subscriptions = yes type = private } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = file:/var/lib/dovecot/db/shared-mailboxes.db sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap lmtp pop3" service auth { unix_listener auth-userdb { group = vmail user = vmail } } service lmtp { inet_listener lmtp { address = 172.16.16.78 port = 24 } user = vmail } ssl_cert = </etc/dovecot/server.pem ssl_key = </etc/dovecot/private/server.pem userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { mail_plugins = acl quota sieve postmaster_address = postmaster(a)mur.at } protocol imap { mail_plugins = acl imap_acl } Regards, -- j.hofmüller Gerüchtegenerator http://plagi.at/geruecht

(Please keep me CC'd, I'm not subscribed) Hi folks, I'm using dovecot 2.1.7 (from Debian stable) with sieve. I have default sieve script configured, which lives in /etc/dovecot/sieve. I use dovecot-lda running under the virtual-mail user, which does not have write access to the /etc/dovecot/sieve directory. Now, when a mail gets delivered, I get the following message in my logs. Jun 25 14:29:43 mail dovecot: lda(2001): Error: sieve: binary save: failed to create temporary file: open(/etc/dovecot/sieve/default.svbin.mail.local.18902.) failed: Permission denied (euid=2009(virtual-mail) egid=2009(virtual-mail) missing +w perm: /etc/dovecot/sieve, dir owned by 0:0 mode=0755) Jun 25 14:29:43 mail dovecot: lda(2001): Error: sieve: the lda sieve plugin does not have permission to save global sieve script binaries; global sieve scripts like /etc/dovecot/sieve/default need to be pre-compiled using the sievec tool Due to the lack of permissions, this is of course expected. However, when I then try to precompile the script using sievec, that also fails: # sievec /etc/dovecot/sieve/default sievec(root): Error: sieve: binary save: failed to create temporary file: open(/etc/dovecot/sieve/default.svbin.mail.local.18952.) failed: Permission denied (euid=2009(virtual-mail) egid=2009(virtual-mail) missing +w perm: /etc/dovecot/sieve, dir owned by 0:0 mode=0755) So, apparently sievec drops privileges to the virtual-mail user. Why does this happen? It seems kind of counter-productive - I don't see a way to properly run sievec as root now? How is this supposed to work? Now I wrote this, I realized that it might be related that I have specified mail_uid and mail_gid globally in my dovecot.conf file. Perhaps those are intended to only be put inside the protocol imap and protocol lda blocks? This would mean duplicating of this bit of configuration, which doesn't really sound nice. Gr.

ot: accepting self certs into win pc?
by voytek＠sbt.net.au 24 Jun '14

24 Jun '14

few month ago, I've got a new Dovecot/Postfix server with self issued certificate (like the previous server), transferred users, all went well EXCEPT for one user on Win/Outlook (or Outlook Express) who tells me his new PC 'doesn't want to accept certificate' (sorry, I'm short on exact details at this time) I need to get it sorted out, I expect it 'should just work' like it did for other users, BUT, before I start looking, trying to 'educate myself' better if any one has any pointers, dos or don't regarding win email clients with self certified server, pls point me that way is using IE with www.dom.com/mycert.crt good point to start ? (after copying mycer.crt to web linked directory first?) thanks, V

Wheezy Dovecot workarounds
by Steve Litt 24 Jun '14

24 Jun '14

Hi all, In switching from Ubuntu to Debian Wheezy (7.5 64bit, network install), I'm finding some surprises in getting Dovecot to work. PROBLEM: As installed, the package manager doesn't give you the dovecot executable. WORKAROUND: To install the dovecot executable, you need to follow these instructions: http://wiki2.dovecot.org/HowTo/DebianStable PROBLEM: Even when you install Dovecot, it doesn't work, as evidenced by the inability of a local email client to talk to it. Further elements of the symptom are that nmap -A -T4 LocalIPAddress, whether LocalIPAddress is the IP of eth0, or 127.0.0.1, fails to find any open ports. Telnet can't operate dovecot at port 143, and openssl can't operate it at 993. However, bizarrly, executing these same commands on a remote machine into the original machine (including accessing the machine's Dovecot from an email client) work perfectly. WORKAROUND To "solve" this problem, do the following raindance as root: ifdown lo ifup lo After the raindance, local access to Dovecot works perfectly, and all nmap commands perform as expected. LOL, hey man, don't shoot me, I'm just the messenger. SteveT Steve Litt * http://www.troubleshooters.com/ Troubleshooting Training * Human Performance

Mangesieve security question
by Vijay Rajah 24 Jun '14

24 Jun '14

Hello, I have a dovecot 2.2.6 on a Linux platform. I have configured manageseive extension. I have opened the manageseive port (4190) to entire world. (since I need my thunderbird and other clients to create seive scripts). I just wanted to know if it is ok to open that port to everyone, and get some feedback on some security measures specific to manageseive. -Thanks in advance Vijay PS: I have taken reasonable server hardening measures. This question is specific to manageseive.

Wishlist: add a variable %{x509} expanding to the client cert in Dovecot-auth
by Guilhem Moulin 24 Jun '14

24 Jun '14

Hi there, As of Dovecot 2.2.9, it's possible to enable passwordless authentication using client certificates [1]: ssl_ca = </etc/ssl/ca.pem ssl_verify_client_cert = yes auth_ssl_username_from_cert = yes (Password checking can be bypassed by returning the extra fields ‘password= nopassword’ in the passdb when the variable ‘%k’ expands to "valid".) However this requires the server admin to set up a PKI. Having a variable %{x509} expanding to the X.509 client cert in Dovecot-auth would remove such hassle and instead provide a way to manage authorized clients in the fashion of OpenSSH's ‘authorized_keys’. Postfix has a similar configuration option: relay_clientcerts [2]. There, the keys for the lookup table can be either client cert fingerprints or public key fingerprints (the digest algorithm can be configured with smtpd_tls_fingerprint_digest). I can't see why %{x509} should digest the certificate and not merely PEM-encode it, but having another %{pubkey} variable expanding to the (PEM-encoded) cert's SubjectPublicKeyInfo block would surely be useful :-) I wonder if there are other folks interested in having the client cert available in the passdb. Thanks, cheers, -- Guilhem. [1] http://wiki2.dovecot.org/SSL/DovecotConfiguration#Client_certificate_verifi… [2] http://www.postfix.org/postconf.5.html#relay_clientcerts

ACL group-override question
by Peter Chiochetti 23 Jun '14

23 Jun '14

Trying to get ACLs working, very basic setup: Virtual users are put into different acl_group via passdb. > u:{PLAIN}B::::::userdb_acl_groups=g The global acl file restricts what they can do. > * group-override=g > * group=g lr Shouldn't this mean, that the group rights override the user rights? The effect that I see though is, that the user "u" then may not do anything, not even lookup and read. The wiki text is not fully clear to me: It tells about disabling access fully (probably by specifying a non-existent group?). But this can only be one way to use group_override… -- peter

ACL group vs. owner question
by Peter Chiochetti 23 Jun '14

23 Jun '14

A hopefully simple question regarding the use of ACLs - the spirit being of taking away most permissions first and then adding them back selectively: In the global ACL declaration I have: > * owner lr > * group=SYS lrwstipekxa The owner is put into the SYS group via userdb extra field in static passwd file ("archiv" is a system user, but pam is disabled for the server): > archiv:::::::userdb_acl_groups=SYS Still, the group permissions do not get applied: > root@host:/etc/dovecot# doveadm -D acl debug -u archiv INBOX > […] > doveadm(archiv): Debug: Added userdb setting: plugin/acl_groups=SYS > doveadm(archiv): Debug: Effective uid=1002, gid=1001, home=/home/archiv > doveadm(archiv): Debug: acl: No acl_shared_dict setting - shared mailbox listing is disabled > doveadm(archiv): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Maildir > doveadm(archiv): Debug: maildir++: root=/home/archiv/Maildir, index=, indexpvt=, control=, inbox=/home/archiv/Maildir, alt= > doveadm(archiv): Debug: acl: initializing backend with data: vfile:/etc/dovecot/dovecot-acl > doveadm(archiv): Debug: acl: acl username = archiv > doveadm(archiv): Debug: acl: owner = 1 > doveadm(archiv): Debug: acl vfile: Global ACL file: /etc/dovecot/dovecot-acl > doveadm(archiv): Info: Mailbox 'INBOX' is in namespace '' > doveadm(archiv): Info: Mailbox path: /home/archiv/Maildir > doveadm(archiv): Info: All message flags are shared across users in mailbox > doveadm(archiv): Debug: acl vfile: file /home/archiv/Maildir/dovecot-acl not found > doveadm(archiv): Info: User archiv has rights: lookup read > doveadm(archiv): Info: Mailbox in user's private namespace > doveadm(archiv): Info: Mailbox INBOX is visible in LIST My question: Shouldn't this work? (In a stock setup.) PS: when I add "* group-override=SYS" to /etc/dovecot/dovecot-acl the user will not even be able to list INBOX. PPS: As an aside, the setup also switches any sytem or /virtual/ users during login in local.conf: > userdb { > driver = static > args = uid=archiv gid=archiv home=/home/archiv user=archiv > } but I get the above result without that switching when I make it read: > userdb { > driver = static > args = home=/home/archiv > } So I suppose that it's not relevant in this case… Thank you in advance -- peter

Setting mail_attach_dir for destination on dsync
by Laeeth Isharc 23 Jun '14

23 Jun '14

Hi. What is the best way to do this, please ? I can override with -o but this applies to source as I read the docs. So I wish to do something like this dsync mirror -u myuser(a)me.com mdbox:/home/mail/myuser/mdboxcopy With either of: 1) attachments stored within message so mail_attachment_dir for dest being blank Or 2) attachments stored in a sub directory of mdboxcopy eg mdboxcopy/attach/ Timo hints that this is possible, but I cannot see how to do this, Any ideas ?

config best practice
by Egbert 20 Jun '14

20 Jun '14

Hi! We will soon start upgrading our Ubuntu mail server (running 2.0.19) from 12.04.1 LTSto 14.04 LTS. The dovecot config is still pretty much in 1.x style; one flat file called dovecot.conf. I can easily switch to a dovecot.conf with the "!include" lines and rename my flat config file to local.conf. I've tested that and it works fine. I could also try to move all lines in local.conf to the different XX-.conf files in the conf.d subdir. What is wise and best practice? Should one edit the files in conf.d? Or will the files in conf.d be overwritten on an update of dovecot? Then I'll better stick to the way of working with the dovecot.conf with the !includes and local.conf and assume that all files in conf.d are default settings. TNX for any advise!

Sis attachment deduplication
by Laeeth Isharc 20 Jun '14

20 Jun '14

Hi. Two questions: 1. Is this now reasonably stable for large mailboxes (c 2mm messages)? 2. Will this leave the filename in the message body unchanged? So for example if I have the same attachment called proposalfromvendor.pdf and proposaltoclient.pdf in two different emails, will the original names be kept ? Or will it replace the filename with some kind of numeric hash ? Many thanks. Laeeth Sent from my iPad

IMAP Chunking Thunderbird
by MrLINK 20 Jun '14

20 Jun '14

Hi, using dovecot-2.0.9-7.el6.x86_64 on CentOS release 6.5 (Final) I have an issue with thunderbird imap chunking. Some attachments are corrupted, because Thunderbird is just storing the first chunk. Since there are some workarounds by editing the "mail.imap.fetch_by_chunks" via about:config this is not the best choice for me because every client has to be edited. Is there a way to set a central value on the dovecot server (i.e disable chunking since this is not a client behaviour only)? Thanks in advance!

Suggestion: Split login_trusted_networks
by Peter Mogensen 20 Jun '14

20 Jun '14

Hi, 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. * It's used for indicating from which hosts you trust logins enough to disable auth penalty. (like in a webmail) However... trustwise, this is trusting two different entities. The first case you put trust in the host. In the second case, you actually put trust in the user which uses the webmail (unless of course the webmail it self implements auth-penalties). 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

Replication and namespaces
by Laeeth Isharc 19 Jun '14

19 Jun '14

Hi. Replication in dovecot is running into trouble as it is trying to sync virtual namespaces and does not like it. dsync parameters With v2.2.9+ you can configure what parameters replicator uses for the doveadm sync command: replication_dsync_parameters = -d -N -l 30 -U The -f and -s parameters are added automatically when needed. Usually the only change you may want to do is replace -N (= sync all namespaces) with -n <namespace> or maybe just add -x <exclude> parameter(s). ........ What is the description of namespace that follows -n or -x? -x virtual Or -x 0/ Where 0/ is the prefix for my virtual namespace Does not seem to stop it trying to sync the virtual namespace... What should I be doing instead? Do I need to use all the parameters above? Or can I just use the -x ? Sent from my iPa

dsync initial replication failing
by Cassidy Larson 19 Jun '14

19 Jun '14

Trying to get my new storage server synced up using dsync replication with SSH. Followed the wiki and everything works great for the initial sync, for about 4 hours, then I get some errors and it stops replicating: dsync-local(user(a)host.com): Warning: Failed to do incremental sync for mailbox INBOX, retry with a full sync dsync-local(user(a)host.com): Error: Remote command returned error 75: ssh -lusername <remote_ip> doveadm dsync-server -uuser(a)host.com -U It happened around 2am. I restarted the new server dovecot process and it started to copy back up again, and then happened about four hours later. I have about 10,000 accounts, and it chugs through the list to replicate pretty well (~300Mbps), so I know it's working. Just not sure why it's failing after it's working so great. Running 2.2.13 on both on FreeBSD. Both show this: # doveadm replicator status Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 5645 Waiting 'failed' requests 0 Total number of known users 9957 Any ideas? Suggestions? Thanks, Cassidy

I think you will hear from proponents of both styles. I would say use whatever works best for you. I personally use one dovecot.conf without any includes because I like having all my configs in one place. Less editing mutiple files, and less forgetting some configuration squirreled away in some conf.d file. Joseph Tam <jtam.home(a)gmail.com>

RFE: dnsbl-support for dovecot
by Reindl Harald 17 Jun '14

17 Jun '14

after having my own dnsbl feeded by a honeypot and even mod_security supports it for webservers i think dovecot sould support the same to prevent dictionary attacks from known bad hosts, in our case that blacklist is 100% trustable and blocks before SMTP-Auth while normal RBL's are after SASL i admit that i am not a C/C++-programmer, but i think doing the DNS request and in case it has a result block any login attemt should be not too complex setup a own honeypot and feed rbldnsd with the sources is quite easy and in case of a own, trustable RBL where no foreigners report somebody by mistake it's relieable and scales well over many machines and services as long services supporting it mod_security: http://blog.inliniac.net/2007/02/23/blocking-comment-spam-using-modsecurity…

[Dovecot] Replication with virtual users and static userdb possible ?
by deano-dovecot＠areyes.com 17 Jun '14

17 Jun '14

Is it possible to get replication working in a virtual user setup that uses a static userdb ? My environment is fairly simple and typical - there's a single system user (vmail) that owns all the home dirs (/var/mail/domain.com/user). The virtual users (userid@domain.com:secretpassword) are kept in a single file (/var/mail/domain.com/PASSWD) that's unique per domain, and referenced as a static userdb : passdb { driver = passwd-file args = scheme=plain username_format=%u /var/mail/%d/PASSWD } userdb { driver = static args = uid=vmail gid=vmail home=/var/mail/%d/%n } I know the wiki http://wiki2.dovecot.org/Replication states that user listing must be enabled, but that's not available for a static userdb. The wiki http://wiki2.dovecot.org/UserDatabase/Static also says that it shouldn't be a problem because it will use do a passdb lookup instead (except for PAM which isn't used here). Unfortunately, it's not working. I've testing with ssh : dsync_remote_cmd = ssh -l vmail %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} mail_replica = remote:vmail@server2.domain.com as well as with straight tcp (SSL for later) mail_replica = tcp:server2.domain.com:999 /var/log/mail.err shows the problems ... Jun 3 11:30:53 server1 dovecot: auth: Error: Trying to iterate users, but userdbs don't support it Jun 3 11:30:53 server1 dovecot: replicator: Error: User listing returned failure Jun 3 11:30:53 server1 dovecot: replicator: Error: listing users failed, can't replicate existing data Anyone else have it working ? I'm sure it's something simple that I've just overlooked. Thanks - D.

Accessing a user mailbox from another user
by Angel L. Mateo 17 Jun '14

17 Jun '14

Hello, I'm looking for something maybe similar to master password but for final users and I don't know if there is already a way I could do it with dovecot. I have accounts that are used by a set of users who know their password. But I now want to remove this shared password and the users has to access to this shared account with their own password. Using shared folders is not an option (at least, not the first option) because of the behaviour our users are familiar with, such as: * They have and manage different sieve filters for the account * They have thier own Sent, Drafts, SPAM... for this shared account and their email client recognizes them as it (because they have its own account). What I'm looking for is something similar to master password, but for a user identifying as another regular user, not the "master" one. Do you know if there already is a way to configure a similar behaviour? I'm planning to configure an user and authentication backend (maybe pam) that gets users as <realuser>$<finaluser> and the realuser password, checks if <realuser> should access to <finaluser> and then returns <finaluser> mail location to dovecot.

Procmail wiki text -- don't muck with SENDMAIL
by era eriksson 16 Jun '14

16 Jun '14

I tried to edit http://wiki2.dovecot.org/procmail but got stuck on the TextCha. Approaching this list instead seems to be a time-tested secondary approach, and I wasn't completely comfortable making these changes without discussion anyway. So here goes. The SENDMAIL= assignment is not only irrelevant, but actually wrong. The note down in the update section about Ubuntu explains the problem well enough, but it applies to all the sections on the page. My proposed edit was to simply remove SENDMAIL and SENDMAILFLAGS from all the recipes on the page, and then remove the Ubuntu section altogether, because it would no longer add anything useful to the page. If somebody in the Dovecot community with edit access to the wiki wants to implement this change, I would be grateful on behalf of the people who try to use Procmail with Dovecot. -- If this were my real .signature, it would suck less. Well, maybe not.

[Dovecot] Pigeonhole and dsync replication not replicating 'SETACTIVE' for a sieve script
by Skeffling 16 Jun '14

16 Jun '14

Hello, I'm testing dovecot replication alongside pigeonhole and liking it. Dovecot v2.2.13 Pigeonhole v0.4.3 If I create or edit a sieve script on one server (via managesieve, using the thunderbird plugin as it happens) then it does get replicated to the other - great! However, if I set a script to be active (SETACTIVE) on one side then this is not being replicated across to the other server. Is this a known issue? Thank you! -- Andrew

[Dovecot] doveadm index - Bug or expected behaviour?
by Bruno Galindro da Costa 13 Jun '14

13 Jun '14

My ldap config is using the variable %d in base search for domain replacement when dovecot will search for users in LDAP. Its works fine for dovecot operation. But, for doveadm index, not. It ignores that variable and tries to pass a base search without domain. So, the search will not working.
