[Dovecot] Filesystem quotas
by Andreas Kasenides 27 Nov '12

27 Nov '12

I could not determine if when using filesystem quotas (http://wiki2.dovecot.org/Quota/FS) Dovecot will use the reported quota and limits without the need of configuring them via "quota_rules". Is this possible somehow? Such a feature would determine the quota limits automatically from the filesystem quotas thereby allowing to make use of them in quota warnings. Dovecot already knows the quota settings and limits. Here is evidence from the logs > Nov 21 19:24:22 iolaos dovecot: imap(user): Debug: box=/Mail/ank > mount=/newmail match=yes > Nov 21 19:24:22 iolaos dovecot: imap(user): Debug: quota-fs: > host=xxxx.xxxx.ucy.xx.cy, path=/mail, uid=211, bytes > Nov 21 19:24:22 iolaos dovecot: imap(user): Debug: quota-fs: uid=211, > value=2779115520, limit=8388608000 I am using (testing) version 2.2alpha1.

[Dovecot] Plugin help, number of messages in mailbox
by Richard Platel 27 Nov '12

27 Nov '12

Hi, We use Dovecot for IMAP and POP (but not LDA), we want to do something when a user has an INBOX that becomes empty, or becomes not empty (set a flag in memcached, but that's not really important). I'm writing a plugin (for Dovecot 2.1.7). On mailbox_open() I can use mailbox_get_status() to get a count of messages in the mailbox, and then decrement this in expunge() or increment it in mailbox save_finish() (for IMAP APPEND or COPY commands). However in expunge() and mailbox_save_finish, even after calling the super function, mailbox_get_status doesn't update the number of messages in the mailbox. This is a problem if (for example) there are concurrent POP sessions. Two POP sessions could get all the messages in INBOX, one could logout, calling expunge a few times, eventually causing my plugin to note that the inbox is empty, then our LDA could deliver a message, mark the INBOX not empty, then the other POP session could log out, call expunge and cause my plugin to mark the INBOX empty, when it's not. So in summation: how can a plugin be notified of changes to a mailbox, and then accurately get the real number of messages in that mailbox?

[Dovecot] Folder layout after Cyrus to Dovecot migration
by Keith Edmunds 27 Nov '12

27 Nov '12

# dovecot --version 1.2.15 We're trying to migrate a server from Cyrus to Dovecot, and we're mostly there. On Cyrus, the folder layout in the MUA is: INBOX subfolder subfolder ... Sent Drafts Queue Trash Users cannot create sibling folders to the Inbox, only subfolders (and sub-subfolders, etc). We've replicated that with: -------------------------------------------------------------------------------- mail_location = maildir:/shared/imapmail/users/%u:INBOX=/shared/imapmail/users/%u:LAYOUT=fs namespace private { separator = / prefix = "INBOX/" inbox = yes } -------------------------------------------------------------------------------- ...however, the Sent/Drafts/Queue/Trash folders are now subfolders of Inbox. Cyrus seems to default to the above layout (at least, I can't find anywhere that defines it). There are no special settings in the MUA to achieve the abovev. Is there a way of replicating the above within Dovecot? We can probably go to V2 if we have to, but 1.2.15 would be preferable. Thanks, Keith

[Dovecot] cannot update mailbox - unable to lock for exclusive access
by 1st WebDesigns 27 Nov '12

27 Nov '12

Hi there, We're using Dovecot version 1.0.7 and Postfix, and since upgrading our Linux box we're getting this in the maillog: Nov 8 07:49:11 server1 postfix/local[27901]: 04B8E7081DA: to=<xyz(a)xyz.com>, orig_to=<abc(a)abc.com>, relay=local, delay=19, delays=0.07/0/0/19, dsn=4.2.0, status=deferred (cannot update mailbox /var/spool/mail/abc for user abc. unable to lock for exclusive access: Resource temporarily unavailable) Postfix is currently set to: mailbox_delivery_lock = fcntl, dotlock Dovecot has this: mbox_read_locks = fcntl mbox_write_locks = fcntl dotlock I've scoured the web and tried all kinds of different locking mechanisms and combinations to no avail. The mail is eventually delivered but on a busy day this can take several hours. In the evening it generally doesn't happen, which leads me to believe it occurs during the day when people have their mail clients open. However, this particular issue doesn't affect every user that has their mail client open, only some! We currently have the mailboxes in mbox format - yes I know we should upgrade to maildir which we will eventually, however we've been using mbox for the last 10 years and this has only become an issue since upgrading. What I have discovered this morning is a Dovecot connection that is open for 6 minutes before disconnection. During this 6 minutes the above problem occurs (new mail cannot get an exclusive lock). The same user will have connected and disconnected several times before and after, with a connection taking no more than a few seconds. But it seems sometimes the connection is taking longer than it should and I suspect the problem lies here. Please can anyone help! Thank you, G

[Dovecot] IMAP proxy - can it detect parodying to itself?
by Graham Leggett 26 Nov '12

26 Nov '12

Hi all, I have some IMAP servers fronted with separate perdition processes, and it would be ideal if I could collapse this down to having dovecot do both the IMAP proxying and the IMAP serving at the same time on the same IP addresses. One of the fields in my LDAP entries contains the canonical name of the server that hosts their mailbox, and if I follow the manual at http://wiki2.dovecot.org/PasswordDatabase/ExtraFields#LDAP I could add the host field to enable proxying. My question is whether dovecot has the ability to notice whether dovecot is being asked to proxy to itself, in other words the value of "host" is the current dovecot server, and when this happens, ignore the proxy and just be a straight IMAP server, because the user has connected to the right box already. Is this possible? Regards, Graham --

Re: [Dovecot] doveadm fails with passdb authentication binds (dovecot 2.0.16)
by mailing lists 26 Nov '12

26 Nov '12

Hello, >> # doveadm mailbox list -u user001 >> doveadm(user001): Error: user user001: Auth PASS lookup failed >> doveadm(user001): Fatal: passdb lookup failed > Are you running this on a Dovecot proxy? It looks like doveadm wants to do a passdb lookup to find out which server should handle this user. Passdb lookups don't work with LDAP binding. But if everything else works then I think you simply shouldn't have enabled doveadm proxying. So, set doveadm_proxy_port back to 0? thank you Timo, setting doveadm_proxy_port to 0 did the trick.

[Dovecot] Missing Messages on IOS device
by David Morsberger 26 Nov '12

26 Nov '12

I just converted my old server running UW/Panda to a Mac Mini Server running Mountain Lion (ML) Server. I'm using the postfix / dovecot setup provided by Apple. My IMAP clients are not showing all my emails. The Mail App on my iPhone and iPad is behaving the worse. I can see the emails that are not showing up in the cur directory. The ML Mail App is stating there are 3854 emails in my INBOX. There are 3948 files in the 'cur' directory ('ls cur | wc -l' returns 3948). Other mailboxes and directories have the same behavior. I'm not sure what to expect here. My method of conversion was to bulk copy (drag and drop) all the messages from one the UW server to the Dovecot server using the Apple Desktop Mail App in Mountain Lion. Any idea why these messages are not showing up on my devices and how I can get them to show up? bash-3.2# /Applications/Server.app/Contents/ServerRoot/usr/sbin/dovecotd --version 2.0.19apple1 bash-3.2# /Applications/Server.app/Contents/ServerRoot/usr/sbin/dovecotd -n # 2.0.19apple1: /Library/Server/Mail/Config/dovecot/dovecot.conf # OS: Darwin 12.2.1 x86_64 hfs aps_topic = com.apple.mail.XServer.fc3bb7c3-c8ef-4fe2-aff3-95ecd927fb11 auth_mechanisms = cram-md5 x-plain-submit plain login apop digest-md5 auth_socket_path = /var/run/dovecot/auth-userdb auth_username_format = %n default_internal_user = _dovecot default_login_user = _dovenull disable_plaintext_auth = no first_valid_gid = 6 first_valid_uid = 6 mail_access_groups = mail mail_location = maildir:/Library/Server/Mail/Data/mail/%u mail_log_prefix = "%s(pid %p user %u): " mail_plugins = quota zlib fts fts_sk managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave mdbox_rotate_size = 200 M passdb { args = /Library/Server/Mail/Config/dovecot/submit.passdb driver = passwd-file pass = yes submit = yes } passdb { driver = od } plugin { fts = sk quota = maildir:User quota quota_warning = storage=100%% quota-exceeded %u sieve = /Library/Server/Mail/Data/rules/%u/dovecot.sieve sieve_dir = /Library/Server/Mail/Data/rules/%u } postmaster_address = postmaster(a)mini.mmpcrofton.com protocols = imap pop3 lmtp sieve quota_full_tempfail = yes service auth { extra_groups = _keytabusers idle_kill = 15 mins unix_listener auth-userdb { user = _dovecot } } service dns_client { unix_listener dns-client { mode = 0600 } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } service_count = 0 } service imap { client_limit = 5 process_limit = 200 service_count = 0 } service lmtp { unix_listener lmtp { mode = 0600 } } service managesieve-login { inet_listener sieve { port = 4190 } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service pop3 { client_limit = 5 process_limit = 200 service_count = 0 } service quota-exceeded { executable = script /Applications/Server.app/Contents/ServerRoot/usr/libexec/dovecot/quota-exceeded.sh unix_listener quota-exceeded { group = mail mode = 0660 user = _dovecot } user = _dovecot } service quota-warning { executable = script /Applications/Server.app/Contents/ServerRoot/usr/libexec/dovecot/quota-warning.sh unix_listener quota-warning { group = mail mode = 0660 user = _dovecot } user = _dovecot } ssl_ca = </etc/certificates/*.chain.pem ssl_cert = </etc/certificates/*.cert.pem ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL:!ADH:!eNULL ssl_key = </etc/certificates/*.key.pem ssl_key_path = /etc/certificates/*.key.pem syslog_facility = local6 userdb { args = partition=/Library/Server/Mail/Config/dovecot/partition_map.conf enforce_quotas=no driver = od } verbose_proctitle = yes protocol lmtp { mail_plugins = quota zlib fts fts_sk sieve push_notify } protocol lda { mail_plugins = quota zlib fts fts_sk sieve push_notify } protocol imap { imap_id_log = * imap_id_send = "name" * "version" * mail_max_userip_connections = 20 mail_plugins = quota zlib fts fts_sk imap_quota imap_zlib imap_fts urlauth } protocol pop3 { mail_max_userip_connections = 6 }

[Dovecot] sieve-extprograms strips Return-Path headers
by Ben Morrow 25 Nov '12

25 Nov '12

The sieve-extprograms extension strips Return-Path headers before passing mail off to the external program. The patch to remove this behavious is trivial (and attached), but since it appears to be deliberate I felt I should investigate further. I believe this is basically a cut-and-paste error. The code to strip Return-Path has been there since the sieve-pipe plugin for Dovecot 1.x, and I believe it was copied from the equivalent code in the 'redirect' action for passing mail off to sendmail(8). In that case, stripping Return-Path is correct, since the message is being resubmitted for delivery (by SMTP or otherwise), and the last step of the new delivery will (should) add a new Return-Path header with the new envelope information. In the case of sieve-extprograms, though, the filtering is happening post-delivery, so a stripped Return-Path will never be replaced. Ben

[Dovecot] Proxy to join two accounts
by Tomek 23 Nov '12

23 Nov '12

Hello, I have server with IMAP on dovecot for user mails and second server on archiveopteryx as mail archive. I'm wondering if it's possible to make some sort of proxy to these two servers in way where: - dovecot server will be main IMAP service with INBOX, etc - I want archiveopteryx account to be something like shared folder with read only access (no delete, no move, etc) in path ex. /archive/user.name - this proxy mappings should allow adding few archive accounts to one user (in case of people replacement) + it will be cool if this mappings could be defined in database so I could write tools to manage archive access for bosses. Is such case possible to achieve with dovecot (any howto or example would be very helpful)? If not - do you know any proxy tools that could allow such configuration? Thanks for any help. Regards, Tomek.

[Dovecot] v2.1.10: Director director_servers order issue
by Bertrand Jacquin 23 Nov '12

23 Nov '12

Hi, I'm setting up an IMAP/POP cluster using dovecot director for some NFS reasons and I'm getting some troubles with director_servers directive. Configuration is shared on both nodes : director_servers = 10.0.50.50 10.0.50.51 director_mail_servers = 192.168.0.150 192.168.0.151 director_user_expire = 15 min 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 } inet_listener { port = 9090 } } service ipc { unix_listener ipc { user = $default_login_user } } Here 10.0.50.50 is node1, 10.0.50.51 is node2 # ring status on node1 director ip port type last failed 10.0.50.50 9090 self never 10.0.50.51 9090 never # ring status on node2 director ip port type last failed 10.0.50.50 9090 self never 10.0.50.51 9090 never self is the same on both nodes, and that generate some cases that can be observed on logs : # logs on node1 dovecot: director: Error: Remote director thinks it's someone else (connected to 10.0.50.51:9090, remote says it's 10.0.50.50:9090) And this is true, TCP packet contain bad DATA : # tcpdump -i eth0 -nn src host 10.0.50.51 and port 9090 -s 0 -w - -l | strings | egrep '^ME' ME 10.0.50.50 9090 # logs on node2 dovecot: director: Error: connect(10.0.50.51:9090) failed: Invalid argument Invalid argument is present as bind() is not done with the appropriate IP : # strace -p 6063 -fF -s 1024 -e trace=bind,connect bind(28, {sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("10.0.50.50")}, 16) = 0 connect(28, {sa_family=AF_INET, sin_port=htons(9090), sin_addr=inet_addr("10.0.50.51")}, 16) = -1 EINVAL (Invalid argument) Also, during this time, CPU is ~100% used. bind() is done with node1 IP address. I also tested using a DNS : director_servers = director-all director-all is two A entries, first containing 10.0.50.50, second 10.0.50.51 and the result here is exactly the same. Using two configurations : # director_servers on node1 director_servers = 10.0.50.50 10.0.50.51 # director_servers on node2 director_servers = 10.0.50.51 10.0.50.50 Give the same result as showed before : # ring status on node1 director ip port type last failed 10.0.50.50 9090 self never 10.0.50.51 9090 never # ring status on node2 director ip port type last failed 10.0.50.50 9090 self never 10.0.50.51 9090 never It seems that first sorted entry in director_servers is considered as "self".

[Dovecot] whoson plugin for 2.0
by Chuck Cochems 23 Nov '12

23 Nov '12

I have found a plugin at ftp://ftp.ufanet.ru/pub/boco/dovecot/whoson-plugin/ I was able to make it function on a dovecot 1.2.8 server, by changing __attr_unused__ to ATTR_UNUSED and strlcpy to i_strocpy (since glibc doesn't HAVE strlcpy, on purpose). However, it doesn't work with 2.1 this is, of course, because getenv() no longer functions lie it used to in plugins. so i need a replacement for getenv("IP") and getenv("USER") to make this work. i know, pop before SMTP is stupid, but the isp i'm doing this for hs customers that have used pop before smtp for ages. so I MUST make a whoson plugin. as i said, the remote ip and the email address are required to interface with whoson. (this is superior to DRAC, which just opens the IP)

[Dovecot] Is there a hook for a plugin to do some transient operation on the mail body ...
by Jay 23 Nov '12

23 Nov '12

... when the MUA has issued a FETCH? I am a Dovecot newbie ... so please bear with me if this is obvious. Basically what I am trying to do is process the mail body (in my own specific way) before Dovecot serves it up to the MUA. I want to do it as a transient operation in memory. So think of the scenario as ... - the MUA issues a FETCH - Dovecot intercepts the FETCH - Dovecot internally gets the mail from the storage into a buffer in memory ----> This is where I'd like to apply a function to the mail body and modify the mail body in the buffer (not in the storage) - Dovecot serves up the (modified) mail to the MUA Looking for a hook that allows me to do it using a plugin. Looks like the zlib plugin does something similar ... applies a decompression function ... but I am not 100% sure. Thanks for your help. -- J.

[Dovecot] maildir and end-of-line encoding
by Christoph Anton Mitterer 23 Nov '12

23 Nov '12

Hi. I just wondered, the following: My MDA may get mails that use LF or CR/LF end of line encodings and deliver them into maildirs. I couldn't find any information about, whether one should or must convert all into one format, cause AFAIK at least on the IMAP side, CR/LF is always used? How does this work on the maildir/backend side of dovcot? Can it work with both and simply automatically convert LF into CR/LF? Thanks, Chris.

Thank you. One thing that still doesn't work is subscribing to all mailboxes via "*", I guess because the folder names start with "." but dovecot mailbbox subscribe wants it without a starting "."

Hi, Is there any code around that lets Dovecot (2.x) aauthenticate via a XMLRPC server (which connects to a LDAP server) instead of going directly to a LDAP server? It could give much more flexibility. TIA Egbert Jan, NL

[Dovecot] v2.1 memory usage
by Timo Sirainen 21 Nov '12

21 Nov '12

v2.1's imap/pop3 processes are linked with OpenSSL by default, because of imapc/pop3c storages. I wonder if you notice any actual (system-global) memory usage reduction when compiling without those and you have thousands of imap processes? ./configure --with-storages=mdbox sdbox maildir mbox cydir I guess I could try it myself also but maybe someone else wanting to reduce memory usage is quicker? :) Related to that, you can look at where imap processes' memory goes with: http://dovecot.org/tools/linux-maps-parse-imap.pl I don't know how much memory those (writable!) file-backed memory areas actually use per-process. Maybe nothing, maybe something..

[Dovecot] users mail folders have to be subscribed
by Andre Bischof 20 Nov '12

20 Nov '12

Hi, I did a migration from cyrus 2.2 to dovecot (fresh installation, details below) via cyrus2dovecot from FU Berlin. That worked, but I first was missing mails in subfolders ander Inbox. No I detected that they are in the users Maildir in folders in his directory. They are listed when using telnet: * LIST (\HasChildren) "." "INBOX.ebay" * LIST (\HasNoChildren) "." "INBOX.ebay.xj" But they are not shown in thunderbird, I have to subscribe to them one by one. I probably did something wrong and maybe messed up with namespace and seperator settings - it would be great if one could lead me out of that. The wiki was a great help installing and configuring everything, but now I'm stuck. I use dovecot 2.1.7 under Ubuntu 12.10: # dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.5.0-18-generic x86_64 Ubuntu 12.10 auth_verbose = yes mail_debug = yes mail_location = maildir:~/Maildir managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation s ubaddress comparator-i;ascii-numeric relational regex imap4flags copy include variab les body enotify environment mailbox date ihave namespace inbox { inbox = yes list = yes location = prefix = separator = . type = private } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster@localhost protocols = imap pop3 sieve service auth { unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { deliver_log_format = msgid=%m: %$ mail_plugins = sieve sieve postmaster_address = postmaster quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r } Any help is greatly appreciated!

[Dovecot] upgrade 1.0.15 -> 2.1.7: MBOX index compatibility and performance
by Benoit Branciard 19 Nov '12

19 Nov '12

Hi, we just upgraded our mailserver from Dovecot 1.0.15 to Dovecot 2.1.7. We use MBOX format (due to legacy compatibility), system users, PAM+GSSAPI auth, filesystem quotas, and indexes located on a separate filesystem: mail_location = mbox:~/mail:INBOX=~/mail/INBOX:INDEX=/var/cache/dovecot/indexes/%16Hu/%u The 2.1.7 configuration files have been rewritten based on default templates instead of converting it from 1.0.15. The server has ~8000 mailboxes and about ~2000 simultaneous IMAP/POP active connexions. The problem is: - indexes seem to be rebuilt: first IMAP/POP connexion for each user thows lots of error messages in the log, and the global index size decreases. Example error log: Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: copy: i_stream_read() failed: Input/output error Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Cached message size larger than expected (27884 > 27855) Nov 19 08:56:38 myhost dovecot: imap(myuser): Error: Corrupted index cache file /var/cache/dovecot/indexes/4/myuser/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 4414 - load average is extremely high (more than 10x the usual one), resulting from an significant increase of disk I/O, and for now (4h after the "monday rush") this doesn't seem to decrease.

[Dovecot] advices for a new installation
by Surviet Amine 18 Nov '12

18 Nov '12

hello everyone, first of all, please forgive my bad english skill, I live in France. On our "old" Dovecot 1.x architecture, we have NFS shares between the front servers (MTA, IMAP...) and mail storage server. I've read some wiki2 pages that present the new director and imap proxy. But I'm still don't see things clearly, so I post here to have your advices to set-up a new mail architecture. The hardware we have : - 24x hard drives in a SAS bay - this bay is directly attached via SAS to a server that I'll call : mail storage server - 2 others servers run ProxMox Virtual Environment The PVE will help us to get many virtual servers : - MX : "mail in" servers - IMAP/POP : our hosted clients services These clients may come from webmail (RoundCube) and others clients (Outlook, Thunderbird, mobile clients...) - RoundCube webmail - MySQL server (hosts in databases accounts and settings for Postfix, Dovecot and RoundCube) - maybe antivirus and antispam servers I've read several threads about NFS and IMAP issues. So I decided to not keeping it. In this scenario, I've tried for the mail receiving part : - front-end (postfix lmtp-client) to mail storage server (lmtp server) that seems to runs fine, now i'll must try to add antispam and antivirus scans Now, for the IMAP part, could you, please tell me, if it is better to : - have several IMAP frontend servers that proxy to the mail storage server or - still keeps NFS between the mail storage server and the frontends Dovecot ? On our Dovecot 1.x webmail use imapproxy. I've read that others proxies exist. We have used for a limited time Perdition. What is the differences between imapproxy, Perdition, nginx imap proxy and Dovecot proxy ? Thanks for sharing your experience of "large mail service" that are solid enought to be scaled.

[Dovecot] Different Mechanism for POP3
by Tim Smith 18 Nov '12

18 Nov '12

Just wondered if there was a way of making the PLAIN an authentication method for POP3S transactions only without making this an option for IMAP? I am attempting to connect to a POP3S server through the GMail interface available through "Accounts and Import". The issue is that there does not seem to be an option to specify the type of mechanism within their interface so I think I have to offer PLAIN along with SSL. Has anyone else had any experience of using the GMail import settings? -- Tim Smith Tel: 01423 564 078 Mob: 07984 398 299 Email: info(a)titan21.co.uk Web: www.titan21.co.uk

[Dovecot] couple questions about dovecot
by Raan Young 18 Nov '12

18 Nov '12

I am attempting to migrate an ancient IMAP server to Dovecot 2.0.9 running on CentOS 6.3, while trying to minimize the impact on users. Most are using Outlook. I have everything working, but have run into a couple of problems, neither horrible, but both weird. It started when I noticed Outlook shows the .subscriptions file in the folder listing. I figured out a way to prevent that (see below), but then decided to attempt the same tactic to move the .imap index structure out of the folder tree and ran into an interesting side-effect. The .subscriptions issue would seem to be a bug, since the documentation I found implies Dovecot should be hiding it from list requests - as it does for the .imap index structure. I made a workaround by using the below mail_location setting. This puts the .subscriptions file above the imap folder structure and hence outside the list scope. mail_location = mbox:~/imap:INBOX=~/mbox:CONTROL=~:INDEX=~/.imap You'll note I have also moved the .imap index. This works, but the full path to the index files has extra layers of .imap. For example, if a folder tree of imap/A/B/C/D exists, where D is the actual mbox format message file, then the index files are stored in .imap/A/B/C/.imap/D. Don't know if this is a bug or I'm misunderstanding something. Can you provide any insight or better solutions for either issue? Some clients are also using iPhones and/or roundcubemail for web access. Those do not have the .subscriptions issue. Raan

[Dovecot] multiple users to same e-mail account with ldap authentication
by Marco Gatti 14 Nov '12

14 Nov '12

Hi, I was looking for a particular case of dovecot configuration I cannot find anywhere. Is there a way dovecot can authenticate via ldap different windows 2008 AD users that have access to the same e-mail account (like user authorization in ms exchange)? For example I want to extend AD schema to let users have 10 email accounts (with multiple domain support). If they are private accounts I think there is no problem at all. But if I want two or more users to access the same mail account what happens? Can I do it with dovecot? Or should I create AD groups and add members to that, to let user access the same mail account? Cheers -- Marco

Hello! I've got dovecot running with postfix. Have virtual users under vmail folder. When I connect with outlook, I can read, delete messages. When I sign on with webmail, also can delete messages, Mutt is working as well on the mail server, can delete messages. Once the message is deleted it moves to the trash. Works as it supposed to. But on Iphone, when I add a mail user, got the mailbox synced with IMAP I can see the INBOX, but when I delete a message, get this error: "Unable to Move Message The message could not be moved to the mailbox Trash." http://www.netchimp.co.uk/webdesign/wp-content/uploads/2011/12/iphone_unabl… What causing this problem?

[Dovecot] Dovecot 2.1.10
by Ralf Zimmermann 14 Nov '12

14 Nov '12

Hi all, I've a problem with dovecot-2.1.10. At time we use dovecot-1.2 without zlib. We setup a new server with dovecot 2.1.10. After syncing the emails everything looks fine. But if we use zlib plugin all new emails have no content. There are a lot of "Error: Maildir filename has wrong S value" log entrys. So we have compiled dovecot-2.0.18 and we use exactly the same configuration. Everything works. What can be our problem with version 2.1.10? Greets Ralf

[Dovecot] dovecot lost mail! Cause?
by Lukas Haase 14 Nov '12

14 Nov '12

Hi, After using dovecot for several years now, today happend something which makes me really feel unconfortable: An email received was just not delivered properly, or, is lost! The mail (from an external server) was sent to two local mailboxes, user1 and user2. user1 received the message but for user2, it *magically* disappeared. MTA is exim4 which definitely processed the messages and handed over to dovecot deliver: 2012-11-12 07:28:21 1TXnVG-00053I-GD SA: [...] id=8644593.887351352701 685934.JavaMail 2012-11-12 07:28:21 1TXnVG-00053I-GD => user1 <user1(a)example.com> R=dovecot T=dovecot_pipe 2012-11-12 07:28:21 1TXnVG-00053I-GD => user2 <user2(a)example.com> R=dovecot T=dovecot_pipe 2012-11-12 07:28:21 1TXnVG-00053I-GD Completed Also, the log of dovecot tells that the mail should have been stored: Nov 12 07:28:21 mail dovecot: deliver(user1): sieve: msgid=<8644593.887351352701685934.JavaMail>: stored mail into mailbox 'INBOX' Nov 12 07:28:21 mail dovecot: deliver(user2): sieve: msgid=<8644593.887351352701685934.JavaMail.orbitz>: stored mail into mailbox 'INBOX' user1 received the mail but user2 not. Since user2 is myself, I *know* that I did not accidently delete any mail or something like that. It was just never received! Disk space is 3GB left, so enough. So I grepped the whole Maildir of user2 for the message ID. There is only one match in the dovecot.index.cache and within that, the most important data of the mail (Message ID, Date, Sender, Receiver, Subject) appears. But apart from that, not a single file! Is there hope to ever find out why what was going wrong here? It feels me veeeeeeeeery unconfortable because from now on I can never be sure any more that all my mails are really received :( :( However, as I said, my mail system processed maybe millions of messages the past 8 years. Although, I can not be sure if that was the case ... :( And help greatly appreciated! Luke PS: Dovecot version 1.2.15 (Debian 6.0.6) with Maildir backend on local harddrive. No NFS, nothing which can go wrong ... PPS: Original log files, just named replaced for privacy.

[Dovecot] Dovecot newbie (migrating from qmail)
by Ajai Khattri 13 Nov '12

13 Nov '12

Ive been using qmail+vpopmail+courier-imap for many years but its time to retire that server so I thought this might be an opportunity to see how I could use Postfix and Dovecot to provide the same services. Im running Dovecot 2.1.9 and Postfix 2.9.4. I have spent a few days reading through some of the docs on the wiki (there's doesn't seem to be any large overview of Dovecot concepts or books so bear with me). Im thinking something simple like passwd-file setup would suffice for me. I want to use completely virtual users. Id like to store mail under /home/vmail/$domain/$user. I think Ive figured out how to do that. But how do I create the maildir? I understand the need to have a mail directory but also a directory for things like sieve - how to specify that? Im thinking the structure would be something like: /home/vmail/$domain/$user/mail <-- mail stored here /home/vmail/$domain/$user/ <-- sieve and other sundry store here Or should the sieve stuff also be under its own folder alongside the maildir? Is it possible to have a separate passwd file per domain? It is possible to combine password and userdb files into one per domain? (I prefer to keep all files related to each domain in its own folder). Also would like to configure Postfix to use dovecot-sasl and I want to use dovecot-lmtp for deliveries. Any good docs / example on those? Later on, I think I want to integrate some kind of virus and spam filtering (amavisd and maybe dspam - anybody used those? would I configure Postfix to handle that or dovecot-lmtp?) Im sure Ill have more questions as I get more complicated but baby steps for now. -- Aj.

[Dovecot] Commercial features in Dovecot future: Object storage, archive
by Timo Sirainen 13 Nov '12

13 Nov '12

Hi all, Dovecot Oy’s web pages at www.dovecot.fi have been updated. The products page lists two features that will be available for commercial licensing, extending the functionality of the basic open-source version of Dovecot. * Storing emails to (high-latency) object storage, initially supporting Amazon S3, Caringo CAStor and Scality. * Email archive storage. See http://www.dovecot.fi/products/index.html for details. I’ve been developing Dovecot for over 10 years now. For a long time it was my primary motivation in life to create the best IMAP server available :) I think I've pretty much accomplished that by now. The future is looking very bright for Dovecot: we will continue the open source development stronger than ever, but in addition, for the long term it needs some additional licensed components that bring the money to cover the cost for future Dovecot development and to be able to build up the support in a professional way. These new features will be added as plugins on top of Dovecot to extend the functionality. Note that I’m not just randomly choosing which features will be open and which will be licensed. Only some specific features will be licensed where my company is going to make money with partnerships and in other measurable ways.

[Dovecot] mbox vs. maildir storage block waste
by Christoph Anton Mitterer 13 Nov '12

13 Nov '12

Hi. I recently mentioned in several posts, that I'd tended to use mbox rather than maildir, because you don't loose so much space (due to always allocating full blocks per maildir file and thus per mail). I made some tests of my archive, which consists of some 3,4 million mails at a total of 42GB). Most of these mails are probably normal sized, but there are also some with bigger attachments. For those who are interested here are the results: I used a 53687091200 B image file (via loop device) and tested ext4 only. btrfs is IMHO not yet ready, I have had often issues with XFS (corruptions), reiser4 is more or less dead and reiser3 is said to have issues (see e.g. its wikipedia article, even though it has that mode for small files which would fit nicely). As you see the number of mails increased a bit, cause I tested over several days... but this is only a very small increase so it shouldn't change the numbers a lot. 1) Original mbox archives (right now in Evolution) mbox exact space: 38122676224 (does not include meta-data) mbox guess space: 44625670144 (includes Evolution meta-data which is several GBs) mbox num mails: 3412999 (occurances of From_ lines) In the following: - image file, 1B-blocks, Used_begin, Used_end, Available_begin, Available_end result out of df -B 1 - mdir exact used space is the sum of du -B 1 for each regular file (i.e. each mdir file) - mdir guess used space du -B 1 on the root dir of the filesystem - mdir num mails: find . type -f | wc -l on the root dir of the filesystem 2) EXT4 with 4096 blocks: image file: 53687091200 1B-blocks: 52844687360 Used_begin: 188555264 Used_end: 45198778368 Available_begin: 49971777536 Available_end: 2444972032 mdir exact used space: 44810866688 mdir guess used space: 45010243584 mdir num mails: 3423296 delta: 6.688190464 G delta / mail: 1953 B 3) EXT4 with 2048 blocks: image file: 53687091200 1B-blocks: 50324295680 Used_begin: 82857984 Used_end: 41598846976 Available_begin: 47557083136 Available_end: 6041094144 mdir exact used space: 41323991040 mdir guess used space: 41516007424 mdir num mails: 3425033 delta: 3.201314816 G delta / mail: 934 B 4) EXT4 with 1024 blocks: image file: 53687091200 1B-blocks: 50314834944 Used_begin: 38287360 Used_end: 39909360640 Available_begin: 47592193024 Available_end: 7721119744 mdir exact used space: 39683908608 mdir guess used space: 39871086592 mdir num mails: 3425033 delta: 1.561232384 G delta / mail: 455 B As you can see, the delta per mail is rather close to the statistically expected values of 2048B, 1024B and 512B. In the end I probably changed my opinion. ~7GB of wasted block space for all my mails is actually quite a lot, but in days of cheap disk space it's acceptable. And with mbox one has IMHO the major disadvantage that mailservers (including dovecot) store some meta-data _in_ it (i.e. in the mails themselves) , which I don't like a lot. I still think about reports that mbox is much faster with full text search (which sounds reasonable)... but therefore one needs probably and database backend anyway. HTH, Chris.

[Dovecot] Invalid Managesieve commands are counted twice
by Christoph Bußenius 12 Nov '12

12 Nov '12

Hi, the Managesieve server closes the connection if it receives an unknown command before authentication: "IMPLEMENTATION" "Dovecot Pigeonhole" "SIEVE" "fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave" "NOTIFY" "mailto" "SASL" "PLAIN" "STARTTLS" "VERSION" "1.0" OK "Dovecot ready." --> BOGUS NO "Error in MANAGESIEVE command received by server." NO "Error in MANAGESIEVE command received by server." BYE "Too many invalid MANAGESIEVE commands." Connection closed by foreign host. Note that only one bogus command has been sent by the client, however the server sends two identical error messages. This seems to be a bug in Pigeonhole 0.3.3. In version 0.2.6, the connection was kept open after the error message. This is actually important to us because we use the "sieveshell" utility which is shipped with the Python "managesieve" package. The managesieve.py module always sends a BOGUS command after the TLS handshake. According to its comments, this is done to work around problems with other server implementations: # Some servers send capabilities after TLS handshake, some # do not. We send a bogus command, and expect a NO. If you # get something else instead, read the extra NO to clear # the buffer. typ, data = self._command('BOGUS') (The full source is at http://pydoc.net/managesieve/0.4.2/managesieve) As a result, sieveshell cannot be used with TLS and a current Dovecot/Pigeonhole server.

[Dovecot] Sieve users script problem.
by Eliezer Croitoru 12 Nov '12

12 Nov '12

I am using Dovecot 2.1.9 which seems to solve older bug in sieve. Now I have another problem with users scripts. I want dovecot to run users scripts but it seems to not even see them. Dovecot runs the default sieve script from home dir but wont see the sieve scripts in the sieve subdirectory and some logs: Nov 10 18:35:54 lda(user(a)domain.local): Debug: Quota root: name=User quota backend=maildir args= Nov 10 18:35:54 lda(user(a)domain.local): Debug: Quota rule: root=User quota mailbox=* bytes=1073741824 messages=0 Nov 10 18:35:54 lda(user(a)domain.local): Debug: Quota rule: root=User quota mailbox=Trash bytes=+32212254 (3%) messages=0 Nov 10 18:35:54 lda(user(a)domain.local): Debug: Quota warning: bytes=1020054732 (95%) messages=0 reverse=no command=quota-warning 95 raw mail user Nov 10 18:35:54 lda(user(a)domain.local): Debug: Quota warning: bytes=214748364 (20%) messages=0 reverse=no command=quota-warning 20 raw mail user Nov 10 18:35:54 lda(user(a)domain.local): Debug: none: root=, index=, control=, inbox=, alt= Nov 10 18:35:54 lda(user(a)domain.local): Debug: Destination address: eliezer(a)domain.local (source: user@hostname) Nov 10 18:35:54 lda(user(a)domain.local): Debug: sieve: include: sieve_global_dir is not set; it is currently not possible to include `:global' scripts.

[Dovecot] Solr 4.0 - lucene - FTS
by Charles Marcus 12 Nov '12

12 Nov '12

Hi Timo, As one who is interested in implementing FTS sometime in the future, I'm curious about what is in store as far as improvements go... Specifically, any plans for implementing immediate/automatic index updates at delivery time? The lack of automatically updated indexes is one downside for its implementation... Also, does the release of Solr 4.0 mean anything for the lucene library used by dovecot? http://www.marketwatch.com/story/lucidworks-congratulates-apache-foundation… Thanks, -- Best regards, Charles

[Dovecot] Sieve puts incoming message into inbox on any problem with submission_host
by Christian Rohmann 12 Nov '12

12 Nov '12

Hello dovecot-users, I have a question/suggestion regarding the submission_host feature of the lda (either via dovecot-lda binary or lmtp) in combination with sieve. When trying to deliver message to a mailbox and this message has a sieve redirect action applied to it, dovecot is using the configured smtp server to forward the message just fine. Unfortunately, if the server configured for submission is unavailable, returns an error or cannot be found via DNS, sieve will simply put the message into the inbox and be done with it: --- dovecot.log --- dovecot: lda(user1): Error: lmtp client: DNS lookup of idonotexist.example.com failed: Name or service not known dovecot: lda(user1): Error: sieve: msgid=unspecified: failed to redirect message to <user2> (refer to server log for more information) dovecot: lda(user1): sieve: msgid=unspecified: stored mail into mailbox 'INBOX' dovecot: lda(user1): Error: sieve: execution of script /mailboxes/user1/.dovecot.sieve failed, but implicit keep was successful (user logfile /mailboxes/user1/.dovecot.sieve.log may reveal additional details) --- /dovecot.log --- The same applies to vacation messages being sent out. Especially with an (unconditional) redirect action, users don't expect to find messages in their inbox. Also problems with the submission_host could very much be temporary and a little delay in delivering a message is better then putting it somewhere the user doesn't expect a message to be. Is there any way to change the behavior of dovecot or the sieve plugin to tempfail in case a message cannot be sent out? I know that with multiple sieve actions it gets more complicated as there could be corner cases were the first message can be sent via the submission server and another message produced by the same sieve script cannot. I'd love sieve to behave like this: a) if submission host is unreachable (hostname wrong, timeout, ...) -> tempfail b) if submission host returns 4xx error -> tempfail c) if submission host returns 5xx error -> fail(-save) and just drop the message into inbox or even have an option to reject the message completely in this case. In case of a tempfail response, the mta simply queues the message and tries again later. In case of a permanent fail the mta will create a bounce message to in form the sender. Regards and have a great weekend, Christian

[Dovecot] quota recalc does not work

Hi I upgraded dovecot from 2.0 to 2.1 , and now i face the quota recalc problem. All settings are keep in mysql Before , after a change in mailbox.quota field, i run doveadm quota recalc and all was ok , but now that command doesn't do anything. After i change a quota for a user , i have to restart dovecot to get the new quota , or do a "doveadm reload" instead of recalc.

[Dovecot] Mails don't get deleted after POP3
by cullinan＠rocketmail.com 09 Nov '12

09 Nov '12

Hi, there! Well, I am new to dovecot, so please be patient with me: I have a virtual server and want to setup simple mail delivery. postfix, saslauthd and dovecot basically work fine. The only open issue is, that (I guess) dovecot doesn't remove the mail when it's retrieved via pop3 from the server. It keeps sending me the same emails again and again. (The mail client (Thunderbird) is configured to remove the messages from the server - it was working already.) I guess that dovecot cannot write to some files / has problems with write permissions. But it doesn't tell me anything... Can you tell me, what configuration might be wrong or how can I enable more debugging to see what dovecot is doing after the mails got sent out via pop3? Here is the configuration: # dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.38-8-server x86_64 Ubuntu 11.04 log_timestamp: %Y-%m-%d %H:%M:%S protocols: pop3 pop3s login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/pop3-login mail_privileged_group: mail mbox_write_locks: fcntl dotlock mail_executable: /usr/lib/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/modules/pop3 auth default: passdb: driver: pam userdb: driver: passwd -----8<----- # dovecot -a # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.38-8-server x86_64 Ubuntu 11.04 base_dir: /var/run/dovecot log_path: info_log_path: log_timestamp: %Y-%m-%d %H:%M:%S syslog_facility: mail protocols: pop3 pop3s listen: * ssl_listen: ssl: yes ssl_ca_file: ssl_cert_file: /etc/ssl/certs/dovecot.pem ssl_key_file: /etc/ssl/private/dovecot.pem ssl_key_password: ssl_parameters_regenerate: 168 ssl_cipher_list: ssl_cert_username_field: commonName ssl_verify_client_cert: no disable_plaintext_auth: yes verbose_ssl: no shutdown_clients: yes nfs_check: yes version_ignore: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/pop3-login login_user: dovecot login_greeting: Dovecot ready. login_log_format_elements: user=<%u> method=%m rip=%r lip=%l %c login_log_format: %$: %s login_process_per_connection: yes login_chroot: yes login_trusted_networks: login_process_size: 64 login_processes_count: 3 login_max_processes_count: 128 login_max_connections: 256 valid_chroot_dirs: mail_chroot: max_mail_processes: 512 mail_max_userip_connections: 10 verbose_proctitle: no first_valid_uid: 500 last_valid_uid: 0 first_valid_gid: 1 last_valid_gid: 0 mail_access_groups: mail_privileged_group: mail mail_uid: mail_gid: mail_location: mail_cache_fields: mail_never_cache_fields: imap.envelope mail_cache_min_mail_count: 0 mailbox_idle_check_interval: 30 mail_debug: no mail_full_filesystem_access: no mail_max_keyword_length: 50 mail_save_crlf: no mmap_disable: no dotlock_use_excl: yes fsync_disable: no mail_nfs_storage: no mail_nfs_index: no mailbox_list_index_disable: yes lock_method: fcntl maildir_stat_dirs: no maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: no maildir_very_dirty_syncs: no mbox_read_locks: fcntl mbox_write_locks: fcntl dotlock mbox_lock_timeout: 300 mbox_dotlock_change_timeout: 120 mbox_min_index_size: 0 mbox_dirty_syncs: yes mbox_very_dirty_syncs: no mbox_lazy_writes: yes dbox_rotate_size: 2048 dbox_rotate_min_size: 16 dbox_rotate_days: 1 mail_drop_priv_before_exec: no mail_executable: /usr/lib/dovecot/pop3 mail_process_size: 256 mail_plugins: mail_plugin_dir: /usr/lib/dovecot/modules/pop3 mail_log_prefix: %Us(%u): mail_log_max_lines_per_sec: 10 imap_max_line_length: 65536 imap_capability: imap_client_workarounds: imap_logout_format: bytes=%i/%o imap_id_send: imap_id_log: imap_idle_notify_interval: 120 pop3_no_flag_updates: no pop3_enable_last: no pop3_reuse_xuidl: no pop3_save_uidl: no pop3_lock_session: no pop3_uidl_format: %08Xu%08Xv pop3_client_workarounds: pop3_logout_format: top=%t/%p, retr=%r/%b, del=%d/%m, size=%s dict_db_config: dict_process_count: 1 managesieve_max_line_length: 65536 managesieve_logout_format: bytes=%i/%o managesieve_implementation_string: dovecot auth default: mechanisms: plain realms: default_realm: cache_size: 0 cache_ttl: 3600 cache_negative_ttl: 3600 executable: /usr/lib/dovecot/dovecot-auth user: root chroot: username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ username_translation: username_format: master_user_separator: anonymous_username: anonymous krb5_keytab: gssapi_hostname: winbind_helper_path: /usr/bin/ntlm_auth failure_delay: 2 verbose: no debug: no debug_passwords: no ssl_require_client_cert: no ssl_username_from_cert: no use_winbind: no count: 1 worker_max_count: 30 process_size: 256 passdb: driver: pam args: deny: no pass: no master: no userdb: driver: passwd args: -----8<----- Please let me know if you need more.

The current stable release is RHEL 6.3, released in June 2012. What is the valid reason preventing you from upgrading to the 6.x distribution? The packages in general in 6.x are 5 years newer than 5.x. And given the fact that RHEL runs miles behind the bleeding edge, you're way behind the curve even with a recent RHEL distribution. You can probably find a much newer version of Dovecot in an RPM somewhere, and Postfix for that matter. But it would be better for you if you simply upgraded to RHEL 6.3. -- Stan

Is there a way I can have something like the following setup: 192.168.0.2 port 110/143, with no starttls/ssl 192.168.0.3 port 110,995/143,993 with starttls/ssl 192.168.0.4 port 110,995/143,993 with starttls/ssl I am looking to setup dovecot so that some IPs will run without any notion of SSL whereas other IPs will run with with ssl/starttls available, each with its own certs

[Dovecot] pop3 exim4 dovecot
by Patrick Shirkey 08 Nov '12

08 Nov '12

Hi, I have an exim4 and dovecot system. The system has multiple accounts. Exim4 is receiving emails in the /var/mail/user files and dovecot is configured to use /home/user/mail (mbox) folder. I have one account that dovecot is not processing replies/bounces/etc... The data is being written in the /var/mail/user file by exim4 but as far as dovecot is aware there is nothing in the pop3 inbox. Can anyone suggest how I can enable dovecot to know that the data is in the /var/mail/user file and deliver it to the pop3 inbox for this account? -- Patrick Shirkey Boost Hardware Ltd

[Dovecot] v2.2.alpha1 released
by Timo Sirainen 08 Nov '12

08 Nov '12

http://dovecot.org/releases/2.2/alpha/dovecot-2.2.alpha1.tar.gz http://dovecot.org/releases/2.2/alpha/dovecot-2.2.alpha1.tar.gz.sig I wanted to start stabilizing v2.2 release some months ago already, but I somehow got stuck adding more and more features. Now it looks like all of the necessary API changes are done, so everything I'm planning on near future can still be added to v2.2 without major changes. The redesigned dsync hasn't had much testing yet, so avoid running it with important mails. Would be nice if people started testing and reporting any bugs. I was going to create some kind of a test suite for testing all the possible syncing combinations and also doing some random stress testing, but I haven't had time for that yet. The new dsync supports doing very fast syncs by saving the resulting state and giving it as command line parameter to the next sync. So for example doveadm sync -s "" > new-state saves the state and doveadm sync -s `cat new-state` continues from the saved state. The replicator code doesn't yet support this. * When creating home directories, the permissions are copied from the parent directory if it has setgid-bit set. For full details, see http://wiki2.dovecot.org/SharedMailboxes/Permissions * "doveadm auth" command was renamed to "doveadm auth test" * IMAP: ID command now advertises server name as Dovecot by default. It was already trivial to guess this from command replies. + Implemented IMAP MOVE and BINARY extensions + Implemented IMAP CATENATE, URLAUTH and URLAUTH=BINARY extensions (by Stephan Bosch). + Implemented IMAP NOTIFY extension. Requires mailbox_list_index=yes to be enabled. + Redesigned and rewritten dsync. The new design makes the syncing faster, more reliable and more featureful. The new dsync protocol isn't backwards compatible with old dsync versions (but is designed to be forwards compatible with future versions). + All mailbox formats now support per-user message flags for shared mailboxes by using a private index. It can be enabled by adding :INDEXPVT=<path> to mail location. This should be used instead of :INDEX also for Maildir/mbox to improve performance. + Improved mailbox list indexes. They should be usable now, although still disabled by default. + Added LAYOUT=index. The mailbox directories are created using their GUIDs in the filesystem, while the actual GUID <-> name mapping exists only in the index. + LMTP proxy: Implemented XCLIENT extension for passing remote IP address through proxy.

Re: [Dovecot] Android ICS stock client and IMAP Capability issue.
by Massimiliano Cianelli 08 Nov '12

08 Nov '12

Hi, Yes w/o prefix work as expected, try to add a prefix like courier does (eg. Inbox.) It will not work as expected. Due I'm upgrading an old installed server, I've to keep everything as much transparent I can... it includes IMAP folder and subscription. Looking at that I've encountered that issue, and analyzed for fix it (thank you open source), not everyone will want to use/use k9.. but you can be 100% sure the stock client is there. Due that Google act like BlackBerry, Microsoft,etc.. (hovewer they will not fix it soon, or really respect the rfc), it's much simple add Namespace on prelogin banner then wait or have to tell someone to install another client for that mailbox. I didn't know the history, but looking at change log seems that idle as been put back to prelogin client for some kind of compatibility with their service. Anyway, the most important reason that got me to subscribe the mailing list for write those emails, is share with the community that problem and provide a solution.. for someone in the future that have the same problem and will search on internet for a solution (like I've does.. before analyze it on my own). If the workaround will be added to the wiki or will be put in the source.. the important thing is that there is a solution simple and fast (two.. the source modify, and the configuration file) and someone can find it.. (Sarcastic) And if the mayans were right we can't wait for google to fix it :p Best Regards Sent from Galaxy Nexus Robert Schetterer <rs(a)sys4.de> ha scritto: >Am 07.11.2012 08:13, schrieb Massimiliano Cianelli: >> Hello, >> >> My phone: >> Android ics 4.1.2 on galaxy nexus. >> And yes, stock mean the default client that come with the os in IMAP mode. >> >> I already know about that configuration parameter, but it will display two time namespace in postlogin capabilities, and so I like much more to adjust the source code to fix the issue. >> >> Yes there is k9 but I didn't like it too much, I prefer the stock client and is much important to keep compatibility with stock client then user-installed client. >> >> About the issue on Google code, there is thr issue on google code... but Google is a lot slow in fixing those things. >> http://code.google.com/p/android/issues/detail?id=1811 >> >> In a few hour I'll update the issue noticing where is hidden the problem. >> >> Regards >> Sent from Galaxy Nexus > >Hi , i shortly tested this with android sdk jelly bean 4.1.1 and "my >setup" dovecot 2.1.10 with included orginal android mail app in imap mode, >,leaving IMAP prefix blank, everything works as expected, no double >shown inbox, namespace problems etc >so you might have to fit your namespace setup. >Also you might follow allready given advice from here. > >Anyway , i understand you using "stock client" >but you have to understand that the producers of mail clients >optimize their stuff fitting best in their own server structure >making money with it, therefor their motivation coding better imap code >is not very high, same case is for outlook and microsoft >however, i would say, fixing bugs is on the google site here, looks like >there is patch >at >http://code.google.com/p/android/issues/detail?id=1811 >and the issue seems long known > >i dont see any hard relation to dovecot in this case >meanwhile using k9mail seems the best way to workaround >there are lots of other bugs around android versions >over the years i dont expect google to fix them > > >> >> Robert Schetterer <rs(a)sys4.de> ha scritto: >> >>> Am 06.11.2012 07:08, schrieb Ben Morrow: >>>> At 6AM +0100 on 6/11/12 you (Massimiliano Cianelli) wrote: >>>>> Hi, >>>>> >>>>> My setup: >>>>> Dovecot 2 latest, installed to replace courrier IMAP, and off course >>>>> configured with the dot separator and all folder under INBOX.*. >>>>> >>>>> The problem: >>>>> My phone was driving me mad during the test, due that it will only >>>>> recognize Inbox. >>>>> >>>>> How found the solution: >>>>> I've started sniffing IMAP traffic on my server and ended up with one >>>>> difference: >>>>> On courier it ask for namespace, on dovecot it won't. >>>>> >>>>> I gives a better look, and noticed that courier show namespace >>>>> capability on prelogin banner, adding it too solved the problem. >>>>> >>>>> Reason: >>>>> Android ICS stock client seems do not honor the capability gived after >>>>> the login. >>>> >>>> See http://wiki2.dovecot.org/Upgrading/2.0?highlight=%28capability%29 ; >>>> you need to set imap_capability and/or get your client fixed. >>>> >>>> Ben >>>> >>> >>> Hi, first ,what is the exact meaning of >>> >>> "Android ICS stock client" >>> >>> do you mean default included email client in standard android in imap >>> mode, when yes, which version of Android , i like to test my own >>> however is there changelog/code etc at google for this behave? >>> >>> conf example >>> >>> # Override the IMAP CAPABILITY response.

[Dovecot] acl and subfolder
by Laurent Foucher 07 Nov '12

07 Nov '12

hello, I'm using dovecot 2.0.16 and i would like to use acl for subfolder.

[Dovecot] Auth USER lookup failed
by Angel L. Mateo 07 Nov '12

07 Nov '12

Hello, I'm running dovecot 2.1.9 and I'm trying to configure shared folders. So, as described at http://wiki2.dovecot.org/SharedMailboxes/Shared I have configured a namespace like this: namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = yes } In one user (user1) I have configured ACLs so another one (user2) has access to a folder. Now, I want to susbscribe user2 to this folder. The problem I have is that whenever I try to list folders for this user (running thunderbird client) I get a panic and an error in the dovecot server (I have attached the complete log). The error says: Nov 6 11:58:56 myotis30 dovecot: auth: Error: userdb(user1): client doesn't have lookup permissions for this user: userdb uid (113246) doesn't match peer uid (14585) (change userdb socket permissions) Nov 6 11:58:56 myotis30 dovecot: auth: Debug: master out: FAIL#0112 Nov 6 11:58:56 myotis30 dovecot: imap(user2): Error: user user1: Auth USER lookup failed Nov 6 11:58:56 myotis30 dovecot: imap(user2): Debug: auth input: Nov 6 11:58:56 myotis30 dovecot: imap(user2): Error: Couldn't create namespace 'shared/' for user user1: userdb didn't return a home directory, but plugin setting quota used it (%h): dict:User quota::file:%h/Maildir/dovecot.quota It seems that imap process running for user2 is trying to a user lookup that fails. So I have manually tried it root@myotis30:/etc/dovecot/conf.d# sudo -u user2 doveadm user user2 userdb: user2 home : <homeDirectory> uid : 14585 gid : 404 root@myotis30:/etc/dovecot/conf.d# sudo -u user2 doveadm user user1 doveadm(user2): Error: user user1: Auth USER lookup failed doveadm(user2): Error: userdb lookup failed for user1 I have checked the socket permissions, but they are 0666 (if I'm looking the right socket): root@myotis30:/etc/dovecot/conf.d# ls -l /var/run/dovecot/auth-userdb srwxrwxrwx 1 dovecot root 0 nov 6 11:43 /var/run/dovecot/auth-userdb In fact, I have tried to put all sockets with permissions 0666 and 0777, but the error persists.

[Dovecot] LDAP congestion
by Bernhard Schmidt 07 Nov '12

07 Nov '12

Hello, I've been asked to have a look at a misbehaving mail server of some colleagues today where almost all logins where failing or excessively delayed, while the LDAP database itself was pretty fast. They run Dovecot 1.2.11 (yes, I know, stoneage) against an LDAP server run by a 3rd party, auth_bind=yes (required). The problem is that this third party LDAP server delays bindResponse 3 seconds when the password is wrong. A user wanted to login every 2-3 seconds this morning with the wrong password, which effectively killed the system because the LDAP connection was mostly stalled waiting for the auth timeout. >From a previous discussion with Timo I know that bindRequests cannot be parallelized in LDAP, so the problem does not come completely unexpected. Other than removing the failure delay in the LDAP server, is there anything one can do? If there is any change in newer Dovecot versions about that please tell me so I can encourage them to upgrade, but I haven't seen anything in the changelog. Any way to get several LDAP workers/connections for passdb in parallel? Thanks, Bernhard

[Dovecot] "starting" dovecot

My system never issues the "dovecot start" command. I do, however, run /usr/local/libexec/dovecot/imap on port 9xxx. I talk to the server through port 9xxx and through the preauth tunnel. Is this arrangement OK? Are there some things that will only work if "dovecot" is invoked?

[Dovecot] Modifying mailbox GUIDs?
by Faheem Patel 07 Nov '12

07 Nov '12

Greetings all, I can view a mailbox's GUID like so: doveadm mailbox status -u guid However, how may I *modify* a mailbox GUID? Can this be done using doveadm or some other tool? If not, how may I go about modifying the dovecot.mailbox.log (where I assume GUID data is stored)? My specific use case has to do with me wanting to modify an existing mailbox's GUID so that its messages are mirrored into a folder of the same name using "dsync mirror". (As we know, dsync utilizes GUIDs to determine mailbox uniqueness) Thanks! -- - Faheem

[Dovecot] Error: Internal quota calculation error
by Micah Anderson 07 Nov '12

07 Nov '12

Hello, I'm using 2.1.7 with seive and mysql quotas. We had an outage the other day where the database server where quotas are stored was not available for a short period of time. In dovecot land, the following types of errors occured in that scenario: Oct 26 22:19:01 grosbeak dovecot: lda(example(a)riseup.net): Error: Internal quota calculation error Oct 26 22:19:01 grosbeak dovecot: lda(example(a)riseup.net): Error: sieve: msgid=<20122132765181x.ABCCE457(a)example.com>: failed to store into mailbox 'Trash': Internal error occurred. Refer to server log for more information. [2012-10-26 22:19:01] Oct 26 22:19:01 grosbeak dovecot: lda(example(a)riseup.net): Error: sieve: script /maildir/e/example/.dovecot.sieve failed with unsuccessful implicit keep (user logfile /maildir/e/example/.dovecot.sieve.log may reveal additional details) I expect that there would be quota calculation errors as dovecot could not reach the database server, but what worried me was the 'failed to store into mailbox' message from sieve. The 'Trash' mailbox in this particular seive script is the correct location for the message to be filed into, but the worrisome message is the 'failed with unsuccessful implicit keep'. I looked through all the message-ids that reported this error and I found that the messages were properly delivered in the end, so this might be some issue interacting between sieve, dovecot and quota and just causing a scary message that can be ignored? thanks for any information you can provide, dovecot is great! micah --

[Dovecot] how to best import Evolution/Thunderbird mail into dovecot?
by Christoph Anton Mitterer 07 Nov '12

07 Nov '12

Hi. I'm migrating all my mail archive (some 60 GB) from Evolution (which is really a broken piece of software) into dovecot. Now I face the problem how to do this best... Evolution (which is still a old 2.32.x version) itself uses mbox files, in a special hierarchical structure to allow subfolders and that like. It also stores it's own status info in X-Evolution and X-Evolution-Source mail headers. Unfortunately,... much of the mail was earlier from a Thunderbird installation, which uses it's own status headers (X-Mozilla*) that were not recognised by Evolution. I have no idea which mbox subformat was always used throughout the different programs and versions... 1) Any way to check for that? To make things worse... Thunder(burden) seems to have used a modified From_ line syntax... "^From -<address> <date>$" Ideally I'd like migrate all mail into dovecot (for storage reasons again, mbox) retaining the different status flags (read, forwarded, etc.) and getting rid of the proprietary headers (of course only when they were. First thing I tried was to simply copy mail within Evolution (i.e. dragging&dropping it from the local folders to the IMAP folders from dovecot). - that preserves the status from Evolution, but doesn't restore that from Thunderbird - it clutters up the information of all From_ lines... "<address> <date>" becomes "<address of my default evolution account> <now>" - neither does it handle the special Thunderbird From_ lines - neither does it remove the Thunderbird or the X-Evolution-Source headers - if Evolution has already had corrupted index files (and this is extremely likely... as it happens even immediately during recreating all of them)... so I may loose mail So my idea was that I need a program that: - can parse all the different mbox formats (those that use the quoted ">From" style and those that use Conent-Length) - can differentiate message headers from body (so that I can drop the proprietary headers and replace them by what dovecot uses as headers) - must of course understand multiline message headers 2) Any idea for a tool like that? The meaning of the X-Evolution and X-Mozilla* headers are easy to find on the web.... so I can convert them. So I basically "just" need a tool that parses all kinds of mbox formats... allow me to drop/add headers... and spits out the rest unmodified. 3) dovecot uses some special headers like X-UID and X-IMAPD... will it create these on it's own, the first time it processes the new mbox file? I mean these headers won't be there after creation. 4) Should I drop out (during) conversion... any other mail headers.. that dovecot uses as it's own? Thanks, Chris.

[Dovecot] sieve
by Christian Rößner 06 Nov '12

06 Nov '12

Hi, is there a sieve option that can reject a mail directly without creating a new mail and sending that out? I know about reject "Reject message goes here"; but I am looking for a mechanism that can reject Mail. Postfix can use reject_unverified_recipient to connect to LMTP and ask if a mail would successfully be enqueued and will return the status gotten from the LMTP server if not. Chances are high that the mechanism would work, too, if Dovecot would know about the sieve rule, while getting a connection on LMTP. Does Dovecot know all rules at this point or is sieve handled after the mail has already been accepted?

[Dovecot] Android ICS stock client and IMAP Capability issue.
by Massimiliano Cianelli 06 Nov '12

06 Nov '12

Hi, My setup: Dovecot 2 latest, installed to replace courrier IMAP, and off course configured with the dot separator and all folder under INBOX.*. The problem: My phone was driving me mad during the test, due that it will only recognize Inbox. How found the solution: I've started sniffing IMAP traffic on my server and ended up with one difference: On courier it ask for namespace, on dovecot it won't. I gives a better look, and noticed that courier show namespace capability on prelogin banner, adding it too solved the problem. Reason: Android ICS stock client seems do not honor the capability gived after the login. Request: Maybe is possible to put namespace capability in prelogin banner for the next version? That will solve trouble with a setup like the mine and android stock email client. Thank you, Best regards Sent from Galaxy Nexus

[Dovecot] Quota
by Christian Rößner 05 Nov '12

05 Nov '12

Hi, is it possible to ask Dovecot for a users quota by talking to the Dovecot server over TCP? I know about doveadm quota -u <user>, but I would like to know, if I can query for that over a network connection (on the Postfix ML they suggested writing a policy service that checks quota. Postfix is not always on the same server as Dovecot is). Does the LMTP protocol give that information somehow? I am not so familiar with LMTP. Or some Unix-Socket to query that could also be configured as inet_listener? Thanks in advance -Christian Rößner -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Axel von der Ohe, Marc Schiffbauer Aufsichtsratsvorsitzender: Joerg Heidrich

[Dovecot] maildir S= and W=
by Christoph Anton Mitterer 05 Nov '12

05 Nov '12

Hi. Even new mails delivered by my MDA don't get the ,S= and ,W= fields set... (but when I "upload" a mail via IMAP to dovecot, they are set) Is there some place in dovecot where I need to enable this? Or would it be the MDA that has to calculate and set this already when placing a file in ./new? Thanks, Chris.

I don't know if Dovecot takes advantage of this in any way though. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] dovecot dimensioning
by mancyborg＠gmail.com 01 Nov '12

01 Nov '12

Hi All, first post here, nice to meet you :) I've been using dovecot + postfix + clamav + spamassassin for years but always with few users. Now i must build a server for 1500 users, they will use various email software (thunderbird, outlook, ..) the webmail (i'm not sure if squirrelmail or roundcube) and blackberry devices (with the BIS service). There will be around 1000 domains (virtual_domains) and postfix will read its users and domains from mysql. Let's say that they will send and receive around 5000 emails per hour (10K in total per hour). I was thinking to use karspersky server instead of clamav. I already have the hardware, it is a server with 4 physical cpu (Intel Xeon E5504 @ 2.00GHz) and 24 gb of ram, do you think it is enough ? Thanks for supporting, regards and have a nice day, Mike

[Dovecot] Out of memory/Managesieve
by Jim Knuth 31 Oct '12

31 Oct '12

Hello, I have here a problem with managesieve. With the login about webmail (roundcube) comes here in the log: --snip dovecot: managesieve-login: Fatal: pool_system_realloc(4294967296): Out of memory dovecot: managesieve-login: Fatal: master: service(managesieve-login): child 10157 returned error 83 (Out of memory (service managesieve-login { vsz_limit=1024 MB }, you may need to increase it)) --snap I've increased of 2048M and the same above. then with 4096 M happens the following --snip dovecot: managesieve-login: Panic: epoll_ctl(add, 61538840) failed: Bad file descriptor dovecot: managesieve-login: Fatal: master: service(managesieve-login): child 9777 killed with signal 6 (core dumps disabled) --snap How can one solve then this? Any ideas greatly appreciated. Thanks. -- Mit freundlichen Grüßen, with kind regards, Jim Knuth --------- Backup interessiert niemanden - Auf Restore kommt es an!

[Dovecot] IMAP proxy between Office 365 client/Sun Messaging Server
by John Dalbec 31 Oct '12

31 Oct '12

I would like to be able to migrate messages from existing end-user accounts on Sun Messaging Server to Office 365 using an administrator login and password. Unfortunately the migration tool for Office 365 doesn't support SASL AUTHENTICATE PLAIN login. The online documentation I've found suggests that I should be able to configure dovecot as an IMAP proxy and have it log in to Sun Messaging Server with AUTHENTICATE PLAIN and encode_base64("user\0admin\0adminpw") in response to a login from the Office 365 migration tool. I'd like to configure dovecot to run only the IMAP proxy if possible. I was thinking of setting all accounts to use the same (strong) password in the proxy. Would anyone be willing to share a sample configuration? Thanks, John Dalbec ellucian Luminis system administrator Youngstown State University

[Dovecot] Unable to get Managesieve working
by Cliff Dunn 31 Oct '12

31 Oct '12

I have Roundcube webmail (v. 0.8.2) running with the managesieve plugin (v. 5.1). I am able to create sieve rules without any problems in Roundcube, but incoming mail is not being processed with the rule I specify. I suspect there is something that isn't configured correctly in dovecot, but unfortunately I am unable to find a resolution online and my very limited knowledge of dovecot isn't allowing me to solve this problem on my own. I am including my dovecot config below. Please keep my knowledge level in mind when suggesting options and let me know if there is any other information I can provide to help troubleshoot the problem. Thanks for any assistance! # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.6 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps managesieve ssl_cert_file: /etc/ssl/certs/postfix.pem ssl_key_file: /etc/ssl/private/postfix.key ssl_cipher_list: ALL:!LOW:!SSLv2 login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login mail_privileged_group: mail mail_location: maildir:~/mail:LAYOUT=fs:INBOX=~/mail/ mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve auth default: mechanisms: plain login passdb: driver: pam passdb: driver: pam userdb: driver: passwd userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix plugin: sieve: ~/.dovecot.sieve sieve_dir: ~/mail/sieve

[Dovecot] lmtp out of memory - raw backtrace
by Daniel Parthey 31 Oct '12

31 Oct '12

Hi, Our setup: - 4 hosts with director and mailbox instance - delivery via director lmtp into mailbox lmtp - mailbox format: mdbox - storage on NFS - OS: Linux 2.6.32-44-server x86_64 Ubuntu 10.04.4 LTS - Dovecot 2.1.10 - Pigeonhole 0.3.3 We're getting strange "out of memory" lmtp errors/backtrace with dovecot 2.1.10 accompanied by high load caused caused by a lot of lmtp deliveries to one user. First action would be to increase vsz_limit to a higher value, but I just want to make sure there is no bug - before blindly increasing this limit. I think it should not crash and corrupt mdbox, even if memory limit is reached: Oct 29 20:14:56 10.129.3.249 dovecot: lmtp(26698, user1(a)example.org) Fatal: pool_system_realloc(16777216): Out of

[Dovecot] POP3 Proxy : user format not accepted
by Christian Gregoire 30 Oct '12

30 Oct '12

Hello, I want to use Dovecot as a POP3 proxy (http://wiki.dovecot.org/HowTo/ImapProxy) All is working fine on my sample platform, except that I have plenty (several thousands) of users that login using local_part#domain, instead of local_part@domain, which is an old setting on my POP3 server. And in that case, Dovecot returns 'Authentication failed'. Here is my proxy table : mysql> select * from tbl_proxy; +--------------------+-------------+--------------------+ | user | host | destuser | +--------------------+-------------+--------------------+ | christian(a)mydom.fr | 10.10.100.1 | christian(a)mydom.fr | | christian#mydom.fr | 10.10.100.1 | christian(a)mydom.fr | +--------------------+-------------+--------------------+ If I login on the Dovecot proxy with the '@' version, everything is fine : root : ~> telnet 10.10.100.24 110 Trying 10.10.100.24...

[Dovecot] Dovecot does not update acl_shared_dict file
by Chris Smith 30 Oct '12

30 Oct '12

Hi all, Firstly, thanks for all your effort with this software. Much appreciated. I am having a slight issues trying to enable reading of other users mailboxes. The docs are a little sparse for those that aren't mailadmin heros, I wonder if anyone could please help me see where I am going wrong. I would like to allow some users to list and read the mailboxes of others. E.g: When User1 logs in, they are presented with a list of their own folders, and those of User2, User3, etc to which they have (e.g. read/list) access I followed the instructions on the wiki (for Version 1.X)- there are two concepts here: 1. Grant some [e.g. list/read] access on a mailbox folder to a particular user 2. Enable the acl_shared_dict to allow dovecot to track (and display to IMAP clients) the folders to which they have access. This will take the form of a BDB file: /var/lib/dovecot/shared-mailboxes.db This file can only be updated by using the SETACL command. *This is where I have the problem*. The SETACL command does nothing. No matter how hard I try, I cannot get dovecot to update this file. The only indication I have that the file exists and is readable by dovecot is the disappearance from the logs of the line: No acl_shared_dict setting - shared mailbox listing is disabled So I can see that dovecot knows the file is there because it does not complain any more. The file is there (because I created it myself, although it is empty: size = 0), and in a moment of weakness I made sure it could be updated (this will be changed back!): ls -l /var/lib/dovecot/shared-mailboxes.db -rwxrwxrwx 1 dovecot dovecot 0 2012-10-30 12:27 /var/lib/dovecot/shared-mailboxes.db But if I try to update the ACL, absolutely nothing happens: [ > command ] [ < reply ] > telnet localhost 143 < * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=CRAM-MD5] Email server > a login [User2] [pass] < a OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH ACL RIGHTS=texk] Logged in > a SETACL Inbox [User 1] rl < a OK Setacl complete.

[Dovecot] Save/restore IMAP session state
by Timo Sirainen 30 Oct '12

30 Oct '12

Some future Dovecot version will have "imap-idle" processes where IDLEing IMAP connections get moved, so the system wouldn't waste so much memory for all the IDLEing imap processes. A week ago I thought I'd see how easy it would be to implement this. I got a basic proof of concept working as a "X-STATE" command. Save the state: a x-state * STATE AQDLW45QdwAAAAMAAABuAQAAAAAAAFAcffYAPHnpFctbjlDbYQAAcEmzCwAA a OK State exported. Restore the state: b x-state AQDLW45QdwAAAAMAAABuAQAAAAAAAFAcffYAPHnpFctbjlDbYQAAcEmzCwAA b OK State imported. This could also be used to implement quick session state restoring for webmails (as suggested by Michael Slusarz). For getting the imap-idle process there would have to be code that: * triggers the session saving when process is IDLEing * figures out what filesystem paths the imap-idle should be looking at (i.e. paths to selected mailbox's dovecot.index.log file and maybe for e.g. maildir new/) * send the session state string, paths and imap connection fd to imap-idle process via UNIX socket * implement the actual imap-idle process * implement a way for imap-idle process to send back the state and connection fd to restore the imap process The patch is ugly and still missing many things. Anyway I thought I'd include it here just in case someone was really eager to continue implementing it. :) I'm not sure when I'll have time for it. A full patch would probably have to have some session_save()/session_restore() functions in lib-storage API. But a quick and dirty way is possible to implement for v2.1 as well, as long as some IMAP extensions aren't used (most importantly rfc5267).

I did consider it, and you're right, it is tricky to get it absolutely right. If robusteness and security was of utmost importance, I would abandon PHP too.

[Dovecot] does dovecot interpret any mail headers specially with maildir?
by Christoph Anton Mitterer 30 Oct '12

30 Oct '12

Hi. For mbox, http://wiki2.dovecot.org/MailboxFormat/mbox#Dovecot.27s_Metadata lists a numer of mail headers: - X-IMAPbase - X-IMAP - X-UID - Status - X-Status - X-Keywords - Content-Length that are treated specially by dovecot. It also suggests, that these should be stripped by the LDA (I guess in order that someone sending you such mail cannot set the status or keywords, or even "attack you" by setting a bogus Content-Length). I wondered, when using maildir, are there any headers that dovecote would treat specially, too? And which I therefore should strip? Thanks, Chris.

[Dovecot] No failover from director to backend?
by Patrick Westenberg 29 Oct '12

29 Oct '12

Hi everyone, short version: Is there no built in failover mechanism for the director service to handle a backend failure? Long version: I have a frontend server running the director service and two backends. Due to maintenance I had to shut down one of the backends which caused connection errors for the users being directed to this backend. I was very surprised as I expected the director to redirect these users to the remaining backend. Am I wrong or is the director not working as expected?

[Dovecot] INBOX permissios woes

29 Oct '12

Hello, I have a dovecot system that uses winbind authentication against Active Directory. I set it up by following the directions in the wiki. That works great. When a new user receives an email, the inbox is created with permissions 600 (rw- --- --) and ownership user:mail , even though I did chmod 02770 /var/spool/mail. And then, when dovecot tries to access the inbox, it throws the error: Oct 29 13:47:59 imap-login: Info: Login: user=<user1>, method=PLAIN, rip=10.0.0.6, lip=10.0.0.26, mpid=29047, secured Oct 29 13:47:59 imap(user1): Error: stat(/var/mail/user1) failed: Permission denied Oct 29 13:47:59 imap(user1): Error: stat(/var/mail/user1) failed: Permission denied Accessing users' Sent, Trash, creating new folders.... all that works fine.

[Dovecot] Overlapping userdb/passdbs
by James Devine 29 Oct '12

29 Oct '12

I have an ldap server for which each entry includes the email address and the username portion of the email address for authentication. Authentication works by username if the username is unique among all the entries. I need to now add some users which must authenticate even if the username is not unique. I figured one way to do this would be to add a second user/pass db which puts further restrictions on the ldap query to make it unique for those users. This doesn't seem to work however as if the user is found in the first ldap query but the password does not match it does not try the second. I would use the password as part of the query but this setup requires me to allow the client to hash the password. Is there a way to do this? Or maybe I am approaching the problem wrong.

[Dovecot] Can Dovecot authenticate against an external email server?
by Marc Perkel 29 Oct '12

29 Oct '12

Just wondering if anyone has done this. I have a spam filtering service where I am now storing spam for users I filter for. It's a filter and forward service so I don't control the recipient's email server. What I would like to do somehow is have the user enter their email address and password and then look up their POP/IMAP server from a database and try to authenticate from it. If sucessful then the user will be able to access their stored spam using Dovecot and Squirrelmail. Any suggestions? Thanks in advance

[Dovecot] Auth caching and password changes
by Angel L. Mateo 29 Oct '12

29 Oct '12

Hello, In my system I have configured auth caching. The problem I have is that whenever a user changes his password, he/she can't login to dovecot after a while and the scenarios described at http://wiki2.dovecot.org/Authentication/Caching are not applied. I have tried also with "doveadm auth cache flush <login>", but it didn't work. He also could to login again if he waits for a time or if I run "doveadm auth cache flush" in the server, flushing all auth information from cache. I have attached the log I had when I changed my password (and suffered the problem). I have attached my doveconf -n too. -- Angel L.

[Dovecot] trash plugin not doing it's job

[Dovecot] Configuring Dovecot & Snarf plugin for the first time
by Jeffrey Ross 29 Oct '12

29 Oct '12

I've been using uw-imap for some time on my linux system and have been running into issues with it so I've decided to move to Dovecote, so far it seems to have solved the issues I've been having however I need/want to move the incoming emails out of /var/spool/mail/{user} in the same (or similar fashion) that uw-imap did, and I found the snarf plugin. However whenever I enable the snarf plugin using the example on the wiki page my email is not loaded and when I remove my configuration for snarf my email re-appears. Based upon what I can tell the snarf plugin is either not loading (but I see it listed in the logs) or simply not working (which is probably because its not configured properly). The system is Fedora 16 (x86_64), the MTA is Exim, and Dovecot is 2.0.21 (version supplied with Fedora). I know I'm making a newbie mistake. Any guidance would be appreciated. Thanks, Jeff dovecot -n provides the following: [root@xyzzy conf.d]# more /tmp/dovecot.changes # 2.0.21: /etc/dovecot/dovecot.conf # OS: Linux 3.4.11-1.fc16.x86_64 x86_64 Fedora release 16 (Verne) mail_debug = yes mail_location = mbox:~/mail:INBOX=~/mbox mail_plugins = " zlib" mbox_write_locks = fcntl namespace default { inbox = yes location = prefix = separator = / } namespace snarf { hidden = yes list = no location = mbox:/run/dovecot/empty:INBOX=/var/spool/mail/%u prefix = /snarf separator = / } passdb { driver = pam } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename snarf = = /snarf/INBOX } service imap-login { inet_listener imap { address = localhost } } service pop3-login { inet_listener pop3 { address = localhost } } ssl_cert = </etc/pki/tls/certs/XYZZY.pem ssl_key = </etc/pki/tls/certs/XYZZY.pem userdb { driver = passwd } protocol imap { mail_plugins = " zlib imap_zlib snarf" } and the logs (in debug) show the following: Oct 20 21:29:45 xyzzy dovecot: imap-login: Login: user=<jeff>, method=PLAIN, rip=98.109.156.118, lip=132.238.254.34, mpid=19627, TLS Oct 20 21:29:45 xyzzy dovecot: imap: Debug: Loading modules from directory: /usr/lib64/dovecot Oct 20 21:29:45 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib05_snarf_plugin.so Oct 20 21:29:45 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib20_zlib_plugin.so Oct 20 21:29:45 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib30_imap_zlib_plugin.so Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: Effective uid=500, gid=500, home=/home/jeff Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: Namespace default: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mbox:~/mail:INBOX=~/mbox Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: fs: root=/home/jeff/mail, index=, control=, inbox=/home/jeff/mbox, alt= Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: Namespace snarf: type=private, prefix=/snarf, sep=/, inbox=no, hidden=yes, list=no, subscriptions=yes location=mbox:/run/dovecot/empty:INBOX=/var/spool/mail/jeff Oct 20 21:29:45 xyzzy dovecot: imap(jeff): Debug: fs: root=/run/dovecot/empty, index=, control=, inbox=/var/spool/mail/jeff, alt= Oct 20 21:29:46 xyzzy dovecot: imap-login: Login: user=<jeff>, method=PLAIN, rip=98.109.156.118, lip=132.238.254.34, mpid=19629, TLS Oct 20 21:29:46 xyzzy dovecot: imap: Debug: Loading modules from directory: /usr/lib64/dovecot Oct 20 21:29:46 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib05_snarf_plugin.so Oct 20 21:29:46 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib20_zlib_plugin.so Oct 20 21:29:46 xyzzy dovecot: imap: Debug: Module loaded: /usr/lib64/dovecot/lib30_imap_zlib_plugin.so Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: Effective uid=500, gid=500, home=/home/jeff Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: Namespace default: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mbox:~/mail:INBOX=~/mbox Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: fs: root=/home/jeff/mail, index=, control=, inbox=/home/jeff/mbox, alt= Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: Namespace snarf: type=private, prefix=/snarf, sep=/, inbox=no, hidden=yes, list=no, subscriptions=yes location=mbox:/run/dovecot/empty:INBOX=/var/spool/mail/jeff Oct 20 21:29:46 xyzzy dovecot: imap(jeff): Debug: fs: root=/run/dovecot/empty, index=, control=, inbox=/var/spool/mail/jeff, alt=

[Dovecot] LDA without lookup as non-root?
by E.B. 29 Oct '12

29 Oct '12

Hello, I'm having some problems getting LDA to work without userdb lookups and have a few related questions. This system has all users in MySQL, each user with unique UID/GID, no local users at all. Installation is from apt-get. 1) If LDA is invoked without lookups, is it correct to assume that the "service auth" and "service auth-worker" can be completely removed from dovecot master configuration? (I have tried commenting them out and logging into IMAP, which seems to work, not sure if anyone else needs the auth service) 2) If LDA is invoked without lookups, will I be unable to use Dovecot quota plugin? Does it need to have a user lookup to get quota info? (haven't added quota support, need to take this one step at a time) 3) The interesting part -- I am invoking LDA from Maildrop. See: http://thread.gmane.org/gmane.mail.imap.dovecot/65473 So when invoked, Maildrop has already dropped to the destination UID/GID and the needed paths are available in the environment. However, using as many permutations of calling LDA as I can think of (based on http://wiki2.dovecot.org/LDA ), I always get this: (command line usage error. Command output: lda: Fatal: Couldn't lookup our username (uid=2500) ) The UID is correct for the target user. If I add "-d $LOGNAME" to my LDA callout, I get permission denied on the userdb lookup, which I guess is another issue to work out if I want to go with lookups. But right now I am trying not to. Why does LDA seem to try for a lookup even when I follow the wiki instructions how to call it without a lookup? 3.5) Related question, my users have separate homedir and maildir, both paths are looked up by Maildrop. I think I need to call LDA with "HOME=$DEFAULT dovecot-lda -f $FROM". Is this correct?

[Dovecot] mail open slowly
by Bernics Gábor | Penta Unió Zrt. 29 Oct '12

29 Oct '12

Hello, I have a dovecot IMAP server (relative small hardware: HP Microserver with 6 Gbyte RAM, linux soft RAID1 with 2x 7200 SATA disk) with 100 Gbyte maildirs. Server works fine but sometimes I can open mails slowly (5-10 sec), typical with new mails. It's intresting when I open an another old mail (with 0 sec wait), after new mail open quickly. Is it dovecot mail indexes or I/O problem? Load and CPU use is small typical 0.10, 10%, I see small IO wait. Debian 6.0, Dovecot 1.2.15, fsync and nmap is disable Best Regards, Gabor

[Dovecot] Active Directory 2003 user database and passwords with special characters
by Boris PINON 29 Oct '12

29 Oct '12

Hello everybody, As explained in the topic, i have troubles with authentication of my users. First of all, sorry for my poor english... I'm running dovecot v1.2.15 on a Debian 6 64bits server up to date. My users database is an Active Directory 2003 (it's important to know that because Active Directory can't retrieve users passwords, you have to bind LDAP with a domain administrator). So, i'm using userdb ldap for authenticated my users and it works ! BUT... When an user having a password with special characters like " ² ° § µ à é è ç à â ê î ô û ù ä ë ï ö ü ", authentication does not work. And in my log file : MY_SERVER | mail/info | dovecot | 2012/08/27 10:42:14 | auth(default): cache(my_user,192.168.7.127): plain(RU0975é*) != 'RU0975Ã©*' As you can see, the character é has been replaced by Ã©.

I want to filter incoming mail into subdirectories. like "from" store at folder "old". the script is: require ["fileinto", "envelope"]; if envelope :is "from" "eliezer(a)test.dom" { fileinto "old"; } else { # The rest goes into INBOX # default is "implicit keep", we do it explicitly here keep; } the result is that the mail is stored in two folders instead of just one, INBOX and old. the logs shows: Oct 23 17:12:26 lda(eliezer(a)ngtech.co.il): Debug: sieve: executing script from /home/vmail/domain/eliezer/home/.dovecot.svbin Oct 23 17:12:26 lda(eliezer(a)test1.dom): Info: sieve: msgid=<5086B3C9.5030909(a)test.dom>: stored mail into mailbox 'INBOX' Oct 23 17:12:26 lda(eliezer(a)test1.dom): Info: sieve: msgid=<5086B3C9.5030909(a)test.dom>: stored mail into mailbox 'old' from unknown reason(or I didnt understood how sieve works?) plugin section from dovecot -n plugin { ... sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +vnd.dovecot.debug +imapflags +relational +comparator-i;ascii-numeric } Thanks, Eliezer

[Dovecot] How to activate antispam plugin
by Xavier Claude 28 Oct '12

28 Oct '12

Hello, I'm using dovecot 2.1.7 from the Debian backports package and I'm trying to get working the antispam plugin with dspam. I have followed the documentation http://wiki2.dovecot.org/Plugins/Antispam but it does not seem to work. The /var/log/dspam folder is empty even after I put mail in the Spam folder. How can I see if the plugin is working and what config option am I missing ? Thank in advance for your help. Here is my config from dovecot -n: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-xenU-6887-i386 i686 Debian 6.0.6 mail_location = maildir:~/Maildir namespace inbox { inbox = yes location = prefix = } passdb { driver = pam } plugin { antispam_backend = dspam antispam_dspam_args = --mode=teft;--deliver=;--user;%u antispam_dspam_binary = /usr/bin/dspam antispam_signature = X-DSPAM-Signature antispam_signature_missing = move antispam_spam = Spam antispam_trash = trash;Corbeille;Trash;Deleted Items; Deleted Messages sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap pop3" service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { mail_plugins = antispam } -- Xavier Claude claude.xavier(a)gmail.com

[Dovecot] Locking /var/mail/user issue with postfix and dovecot
by Robert JR 27 Oct '12

27 Oct '12

Hello, I have a question regarding mailbox locking and hope any one can help me to better understanding the locking of mbox My Postfix lock option is fcntl dotlock mailbox_delivery_lock = fcntl, dotlock virtual_mailbox_lock = fcntl, dotlock My Dovecot lock option is fcntl only mbox_write_locks = fcntl mbox_read_locks = fcntl now, when user is download a large mail (20 MB) for example, dovecot locks /var/mail/user with fcntl until the users finish downloading the mail ok here comes my question. While the user is downloading the mail , a mail arrives so postfix make some thing weird 1- Postfix creates /var/mail/user.lock for 5 secs , then postfix defer the mail with reason that the /var/mail/user is locked and then delete the /var/mail/user.lock (after 5 secs) My question is ? why postfix create user.lock although it shouldn't because already dovecot fcntl it … 1- Dovecot locks /var/mail/user using FCNTL 2- Posttix at the same time tries to FCNTL /var/mail/user .. but it fail since dovecot already fcnl it. 3- Postfix at the same time add dot lock /var/mail/user for 5 secs then remove the lock. the question is how come postfix dot lock /var/mail although it couldn't FCNTL the file in the first place ??????? what i was expecting is 1- Dovecot locks /var/mail/user using FCNTL 2- Postfix tries to FCNTL /var/mail/user 3- POSTFIX WILL NOT CREATE DOTLOCK file unless the FCNTL is released by dovecot!!!! Please advise if postfix will dot lock the file even if it couldn't FCNTL the file in the first place…… Regards

I downloaded and examined it; it's just a wrapper for /usr/bin/passwd, and there doesn't seem an easy way to modify it to use something other than the system password file.

[Dovecot] dovecot-lda delivery to Maildir/cur as 'seen'?
by Dale Gallagher 26 Oct '12

26 Oct '12

Hi I've added a server-side feature where authenticated customers sending through our SMTP server have their outbound mail copied to their Sent folder (like Gmail does). The delivery script called by qmail calls dovecot-lda to deliver it to the user's Sent folder. The problem now, is that the Sent folder shows the mail as unread, which MUAs flag (and notify, in the case of some). I've searched the docs and mailing list, but can't find an option to tell dovecot-lda to mark the mail being delivered, as seen/read. If I've missed something, please let me know. If not, then I think it might be a good idea to add a feature to dovecot-lda permitting one to specify delivery to the ./cur subfolder of a Maildir, instead of ./new. Thanks

[Dovecot] Shared folders not shown if "INBOX.shared.%.%" is used with dovecot 2.1.10
by Christoph Bußenius 26 Oct '12

26 Oct '12

Hi, Thunderbird uses the following IMAP command to list shared folders: . list "" INBOX.shared.%.% Dovecot 2.1.10 does not list any folders in response to this command. Dovecot 2.0.21 does list them: * LIST (\HasNoChildren) "." "INBOX.shared.user1.folder" . OK List completed. Both versions list the folders if "*" is used instead of "INBOX.shared.%.%". Because of this issue, shared folders are not shown in Thunderbird. The ACL of the folder in question is ACL "keilrwtscd" for user1 (who is trying to access them using Thunderbird). config: # 2.1.10: /usr/local/dovecot/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-42-server x86_64 Ubuntu 10.04.4 LTS disable_plaintext_auth = no mail_gid = vmail mail_location = mdbox:~/mail mail_plugins = acl mail_uid = vmail namespace { inbox = no list = children location = mdbox:%%h/mail prefix = INBOX.shared.%%u. separator = . subscriptions = no type = shared } namespace default { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = scheme=CRYPT username_format=%u /usr/local/dovecot/etc/dovecot/users driver = passwd-file } plugin { acl = vfile acl_shared_dict = file:/mail/shared-mailboxes } protocols = imap pop3 service auth { unix_listener auth-userdb { group = vmail mode = 0660 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /usr/local/dovecot/etc/dovecot/users driver = passwd-file } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_max_userip_connections = 20 mail_plugins = acl imap_acl acl } Cheers, Christoph -- Christoph Bußenius Rechnerbetriebsgruppe der Fakultäten Informatik und Mathematik Technische Universität München +49 89-289-18519 <> Raum 00.05.040 <> Boltzmannstr. 3 <> Garching

[Dovecot] Small issue with "submission host"
by Raphael Ordinas 26 Oct '12

26 Oct '12

Hi everyone, I'm facing a small issue with the lda/lmtp "submission_host" feature in dovecot 2.0.14. When sending mail to MTA (in case of sieve filter forwarding for example), dovecot pass a RCPT TO command just after the EHLO. He's missing the MAIL FROM command. Therefore, my MTA show me a warning like this : "improper command pipelining after EHLO". How can i solve that ? Regards, Raphael

[Dovecot] Public folders and groups
by b m 26 Oct '12

26 Oct '12

Currently I have dovecot working with Active Directory authentication and public folders with acl. In acl I have the users I want to access the public folders. It'll be easier for me to use one group instead of 50 users but I can't get it to work. From where does dovecot get the "group" attribute for a user? Can it read the groups that a user belongs from AD?

[Dovecot] Snarf plugin
by Jeffrey Ross 26 Oct '12

26 Oct '12

I've now upgraded dovecot from 2.0.21 to 2.1.10 and the good news is I no longer see dovecot crashing when loading the snarf plugin however snarf still does not do anything except make the inbox disappear. I've come to the conclusion that either snarf does not actually work, possible, but I doubt it, or more likely I have a configuration issue preventing it from working. The system is simple, all email is stored in /var/spool/mail/{username} and I want all the mail moved to ~/mbox when the user logs in via imap, similar to uw-imap. Any guidance would really be appreciated.

[Dovecot] Creating Maildir and populating with emails via external Python process
by Bradley Rintoul 26 Oct '12

26 Oct '12

Hello: I'm using Dovecot to provide IMAP services for Thunderbird clients. The user's mail is stored in Maildir format and the individual emails which the user "receives" are actually downloaded and put into the Maildir "repository" using a Python email client (POP3 client). I am trying to create the dovecot-uidlist file and maintain the "next UID" value within it, but I am having trouble with the UIDVALIDITY and the 128 bit mailbox global UID among other things. How can I "seed" a dovecot-uidlist file with these values..? Sorry if the information is not much to go on, please let me know what more information you might need to help point me in the right direction. Thanks, B. RIntoul

[Dovecot] spamc can't seem to call /usr/lib/dovecot/deliver

Hi, My server uses a system comprised of postfix, dovecot and dspam to filter and deliver mail. Postfix used the following flags in calling spamc and dovecot: flags=DRhu user=dovecot:secmail argv=/usr/bin/spamc -u ${recipient} -e /usr/lib/dovecot/deliver -d ${recipient} after an upgrade from Debian lenny to squeeze we were able to get everything working except spam filtering. Spamassassin is able to judge whether the mail coming in is spam but everything stops there.

[Dovecot] dovecot auth against AD on samba4
by Carsten Laun-De Lellis 24 Oct '12

24 Oct '12

Hi group I am currently running a mail server on ubuntu 11.04 with postfix 2.8.5, dovecot dovecot 2.0.13 and openldap 2.4.23. I have now read about sogo and I am thinking about installing it because of it's native outlook support capabilities. The ZEG appliance wouldn't be an option for me because I use a virtual server from a provider where I can't install my own vm or even an iso. When I go thru the documentation there is a part with installing OpenChange based on samba4. As far as I understood the OpenChange authentication is against the samba4 AD. Actually there is no support in syncing the AD against an OpenLdap Server and I would have to change the OpenLdap port because the AD is listening on port 389. To change the port wouldn't be a big deal, but what i was thinking about to run the dovecot auth also against the samba 4 AD. I searched around on the internet but didn't find a doc yet how to do that. Does anyone here could provide me with a link or a how-to ? Thanks very much in advance.

[Dovecot] Clarifications on Pigeonhole and MySQL lookups
by Sandro Tosi 24 Oct '12

24 Oct '12

Hello, we're scouting if it's possible to use Pigeonhole (currently v0.3.1, as this will be provided with an upcoming Debian package) with MySQL dict lookups with the mail setup we're designing. Our (main) goals are: 1. store the filters on the database 2. allow each user to enable/disable any of the filters set we provide (it's a static set of some general filters, available to all the users; we're currently not providing the possibility to users to write their own filters) For point 1) we already see[1] that's possible, but it uses the map construct that might not fit with our current database structure: we have a domain table (storing the domain info) and a mailbox table (storing the mailbox info, but the username is composed by the local part, stored in this table, and the domain part is a FK to the domain table, using an id). Do you think it's possible to run a join query on domain+mailbox to retrieve the mailbox_id needed to query the table for the filters? Or do we have to create the filter table and store the local(a)domain.ext info there ("relaxing" the integrity relationships between tables)? How do we specify which filters are enabled for any given user? We originally thought of an "Enabled" field on the filter table, but in the example in the doc[1] I hadn't seen a way to do that: it seems like the filter list is specified in the proxy definition - am I wrong? How can we do that? [1] http://hg.rename-it.nl/dovecot-2.1-pigeonhole/file/e9ed5d5cef4b/doc/script-… I think it's enough for now, maybe additional questions will arise going deeper in details :) Thanks in advance, -- Sandro Tosi Product Engineer Shared Hosting Products R&D | Dada.pro eml sandro.tosi(a)register.it

[Dovecot] Maildir hardlinks

Hello list, Excuse me for my poor english. I have updated on a test server dovecot 2.0.13 to dovecot 2.1.1. All works fine, but with the new version it seems that dovecot don't do hardlinks when deliver a message to multiple users. I have checked my config and the only rule I can see aboout that is maildir_copy_with_hardlinks = yes in /etc/dovecot/conf.d/10-mail.conf My mail location config is mail_location = maildir:~/MailDir:LAYOUT=fs I tryed using lmtp directly issuing 'telnet localhost 24' and sending a test message to 3 recipients. Then issuing a 'ls -il' in the "new" directory of that users, I saw the inode was not the same. I rechecked my config and take a look in the wiki and in the list for someone who had the same problems, but found nothing. Maybe I did something wrong, but I can't understand what. Can you help me?

[Dovecot] index files created improperly in dovecot 1.2.16
by john roman 23 Oct '12

23 Oct '12

Greetings, It seems to be a problem that ive seen occasionally on the web with few results as to a solution, but im experiencing it as well. Namely, dovecot creates index logs for users with a 600 permission, when it should create with a 700 permission. My indexes are stored in /var/indexes with the directory at 777 permission, the users are identified in MySQL. The error is as follows: Oct 23 09:03:13 mailer01 dovecot: POP3 (johnr(a)testing.com) stat(/var/indexes/j/johnr(a)testing.com/.INBOX) failed: Permission denied (euid=10509305(x10509305) egid=81607(pg199275) missing +x perm: /var/indexes/j) the permissions of /var/indexes/j are 700, owned by the euid and egid effectively. the only file that does not have this permission is in /var/indexes/j/johnr(a)testing.com/.INBOX/dovecot.index.log, at 600.

[Dovecot] 76Gb to 146Gb [Resolved]
by Spyros Tsiolis 23 Oct '12

23 Oct '12

Hello all, I would like to thank you all for your kind replies and feedback in regards to migrating from a smaller hdd to a bigger one (namely from 72gb to 146gb). I finally found a painless way of doing this. Since I believe that this is still an off-topic post, if anyone is interested in the solution i've adopted for this, let me know by replying to me privately. If, however, you don't mind me posting here, let me know. Many many thanks go to Alexander Hoogerhuis, the "mad Norwegian" :-) who helped me on this too much to describe here. Alex, you are a true sport. Thank you again people. All the Best, spyros ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis

Hi, Is there any option in Dovecot that enables logging the full path of where a message is saved in the backend? Dominic

[Dovecot] (new) director issues in 2.1.10
by Kelsey Cummings 23 Oct '12

23 Oct '12

Timo - I upgraded to 2.1.10 on our director servers two nights ago and apart from errors associated with the directors processes restarting everything looked great for ~24 hours until I failed our the real servers last night to update the nfs mount options for the spools. I followed the suggested procedure for each backend server, just run on one of the directors, which seemed to work as expected. doveadm director add x.x.x.x 0 doveadm director flush x.x.x.x The following errors on the directors that started after this went unnoticed until this AM. director: User bb host lookup failed: Timeout - queued for 30 secs (Ring synced for 36 secs) director: User cc host lookup failed: Timeout - queued for 48 secs (Ring synced for 66 secs, user refreshed 12 secs ago) director: User dd host lookup failed: Timeout - queued for 124 secs (Ring synced for 119 secs, weak user, user refreshed 155 secs ago) director: User ee host lookup failed: Timeout - queued for 79 secs (Ring synced for 119 secs, weak user, user refreshed 113 secs ago) ... User ff host lookup failed: Timeout - queued for 30 secs (Ring synced for 7427 secs, weak user, user refreshed 620 secs ago) This continued, combined with occasional login timeouts (as reported by some internal imap clients.) The login delays/timeouts got bad enough that our load balancers dropped both the servers while I was investigating. They seem to be okay after being restarted. -K

[Dovecot] auth timeout state=2, bad?
by Bernhard Schmidt 22 Oct '12

22 Oct '12

Hello, we run Dovecot 2.1.7 as SASL backend for our Postfix SMTP-AUTH farm and see this error message occasionally Oct 22 16:15:32 lxmhs52 dovecot: auth: PLAIN(?,xx.xx.xx.xx): Request 0.21 timeouted after 150 secs, state=2 Since it is mostly the same IP repeating I'm assuming it's a client issue. Is that correct? What could cause this? Can we safely ignore it? Thanks, Bernhard

[Dovecot] Marking all mail in one folder of public mailbox as read
by Frerich Raabe 22 Oct '12

22 Oct '12

Hi, I'm running Dovecot 1.2.17 on FreeBSD 9 to serve an archive of a few internal mailinglists. The archive is implemented using a public namespace: namespace private { separator = / prefix = inbox = yes } namespace public { separator = / prefix = Lists/ location = maildir:/home/vmail/lists/Maildir:CONTROL=~/Maildir/lists:INDEX=~/Maildir/lists subscriptions = no } As you can see, the CONTROL/INDEX files are stored per-user to allow private \Seen flags. The different mailinglists are all sent to the 'lists' user which has a Sieve script to file them into different folders, so I have directories on my harddisk like /home/vmail/lists/Maildir/.somelist /home/vmail/lists/Maildir/.anotherlist Now, I'd like to mark the mail in *one* of those folders as \Seen by default. If the INDEX files weren't per-user, it would simply be a matter of using 'addflag "\Seen";' in the Sieve script of the lists user. Alas, this has no effect. Hence my question - how can I have the mail of just one mailinglist get marked as "read" for all users? So far, the only option I see is to add a second public namespace, with a different prefix - and this namespace doesn't use private CONTROL/INDEX files. However, I'd like to keep using the "Lists" prefix if possible to avoid too many changes to the clients. -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

The dict is also needed for quota lookup from the database. The only thing which might be omitted is the global quota_rule since it is returned by the userdb/passwd in any case, but I'm not sure what happens if you only configure a "quota_rule2" without configuring a "quota_rule". > My outstanding issue is whenever I as the root mysql user update a > user's quota the other user also gets an update, I noticed with one > the messages column on the other user went from 0 to 2, another time > the quota value went up from 0 to 3500 it seems random. You should not be accounting the actual mailbox usage in the same virtual_users table as the quota is read from.

Dovecot stores the current storage and mailcount in there. These columns should be different from the columns defining the maximum limit. Regards Daniel

[Dovecot] still having difficulties with per-user quotas
by David Mehler 20 Oct '12

20 Oct '12

Hello, I am trying to get per-user quotas working. My thanks to all who have helped so far. To recap I am running Dovecot 2.1 and Mysql where I've got my virtual users. All virtual users are under the system user vmail with a UID and GID of 5000. Looking over the wiki docs I've added a quota table and got the dict service working, I am not having problems with permissions or the login username and password, all that is working fine. Here's my current doveconf -n output it is producing the following debug error related to the userdb sql query: # 2.1.10: /etc/dovecot/dovecot.conf # XXX dict { quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } first_valid_gid = 5000 first_valid_uid = 5000 hostname = XXX last_valid_gid = 5000 last_valid_uid = 5000 mail_location = maildir:/home/vmail/%d/%n:LAYOUT=fs mail_plugins = " quota" namespace inbox { inbox = yes location = prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { quota = dict:User quota::proxy::quota quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u } protocols = imap service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { mode = 0600 user = vmail } } service dict { unix_listener dict { mode = 0600 user = vmail } } service imap-login { inet_listener imap { address = 127.0.0.1 ::1 } inet_listener imaps { address = xxx xxxx ssl = yes } } service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = vmail } ssl_cert = </etc/ssl/certs/server.crt ssl_key = </etc/ssl/private/server.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { mail_plugins = " quota imap_quota" } Oct 19 15:23:52 auth-worker(29279): Info: mysql(/var/run/mysqld/mysqld.sock): Connected to database mail Oct 19 15:23:52 auth-worker(29279): Debug: sql(xxx,::1): query: SELECT user as user, password FROM virtual_users WHERE user='xxx@domain'; Oct 19 15:23:52 auth: Debug: client passdb out: OK 1 user=xxx Oct 19 15:23:52 auth: Debug: master in: REQUEST 3523346433 29276 1 f5cd16e3f5e078c28d850749e42c86cc Oct 19 15:23:52 auth-worker(29279): Debug: sql(xxx,::1): SELECT concat('*:storage=', bytes, 'M') as quota_rule FROM quota WHERE username='xxx'; Oct 19 15:23:52 auth: Debug: master userdb out: USER 3523346433 xxx quota_rule=*:storage=368485M Oct 19 15:23:52 imap-login: Info: Login: user=<xxx>, method=PLAIN, rip=::1, lip=::1, mpid=29282, secured, session=</xKpcW7MFgAAAAAAAAAAAAAAAAAAAAAB> Oct 19 15:23:52 imap(xxx): Error: user xxx: Couldn't drop privileges: User is missing UID (see mail_uid setting) Oct 19 15:23:52 imap(xxx): Error: Internal error occurred.

[Dovecot] Dovecot 2 and TCP-Keepalive
by Sven Hartge 20 Oct '12

20 Oct '12

Hi! I am about to migrate a perdition-based IMAP/POP3 proxy to Dovecot. Unfortunately some users are behind a firewall/NAT setup which throws away seemingly idle TCP connections sooner than the established default of 24 hours (more likely after 30 minutes ...) resulting in all kinds of weird client behavior. And unfortunately² this firewall/NAT setup is outside of my control and I have no means of correcting this (in my opinion) flawed configuration. Now, with perdition I was able to use the --tcp_keepalive option which totally solved the mentioned weird client behavior. My question is: does Dovecot2 use TCP-Keepalive on its sockets per default or do I need to enable it some way I have not yet discovered? The manual and wiki only talk about "keepalive" in connection with the IMAP protocol and IDLE and my C-fu is too weak to understand the source code. Grüße, Sven. -- Sigmentation fault. Core dumped.

[Dovecot] Question about salted hashes
by Tobias Maffert 19 Oct '12

19 Oct '12

Hello. I'm switching from b1gmail to my own setup which consists of Postfix+Dovecot+MySQL (and maybe VBoxAdm). There are two problems: - b1gmail is using unsalted MD5 hashes. Is there any good way to make my new setup backward compatible? So I don't have to force all of my 50k users to change their password. - How do I change my setup to salted SHA256 (or an even better algorithm). And how do I make the hashes compatible between Postfix, Dovecot, MySQL (and maybe VBoxAdm)?

[Dovecot] Emails from invalid local accounts
by Steven Kiehl 19 Oct '12

19 Oct '12

Hi, I'm using dovecot 1.2.9 in a postfix/dovecot setup and I'm having issues with receiving spam where the "from" header contains an address like accounting(a)mydomain.com. Is there some way I can filter out these emails coming from outside our network with an account associated with our network which doesn't exist? Do I just need to configure some custom process to evaluate these addresses, or is there some way either in dovecot or spamassassin to do this? Thanks, Steve K

[Dovecot] lmtp proxy logging
by Jack Bates 18 Oct '12

18 Oct '12

The logging on lmtp and lmtp proxy is pretty limited from what I can see. It seems to handle errors, Connect, Disconnect, and in the case of lmtp delivery, it logs where an email is saved to. The lmtp may be enough, "connect, saved user, saved user..., disconnect", but I was curious if it is worth while to add more info logging for the proxy, primarily which recipients are sent to which proxy. I was thinking of local patching it, but I'll generate up something more inline with official code if it is desired. My thought is to show 1 entry for each recipient, and the destination server chosen. If I recall correctly, the proxy code doesn't actually listen in on the conversation, so logging results would probably complicate the code. Jack

[Dovecot] Problem with process_limit
by FABIO FERRARI 18 Oct '12

18 Oct '12

Hello, i have a problem with the process_limit configuration. Occasionally, it happens that the dovecot.log shows this line: master: Warning: service(imap): process_limit reached, client connections are being dropped So I checked, the process number, with the command: ps auxwww | grep imap | grep -v login | wc -l and it shows 1024. Then, i edited the file /etc/dovecot/conf.d/10-master.conf and set the line process_limit = 1500 I checked if the dovecot had accepted the change with the command doveconf -n | grep process_limit and it shows process_limit = 1500 But it is dropping the connections when they reach 1024 anyway, the configuration parameter is totally ignored. Can anyone help? Am I editing the right parameter? thanks in advance Fabio Ferrari P.S. The version of the dovecot is dovecot-2.0.1-1_118.el5 on Red Hat Enterprise Linux Server release 5.8 (Tikanga).

[Dovecot] real_rip variable addition for dovecot 2.1.10
by Jack Bates 18 Oct '12

18 Oct '12

Timo, Please check the code. I didn't add it, but a real_lip might be useful for some people as well. Also, I notice that pop3-proxy is doing a different xsession than the imap proxy. Is there an xsession standard that is different between the two, or just an oversight in the code? Both send the remote address/port, but only imap proxy sends the local address/port. This patch declares long variable %{real_rip} so that a backend server can declare a different login_log_format_elements login_log_format_elements = user=<%u> method=%m rip=%r lip=%l pip=%{real_rip} mpid=%e %c This is primarily useful for backend servers to log both the rip, lip, and in case of xsession, the real rip. I haven't done extensive testing yet, but as long as nothing does anything weird elsewhere in the code, it should be good. http://www.brightok.net/jbates/dovecot-2.1.10-real-ip.patch dovecot: pop3-login: Login: user=<test>, method=PLAIN, rip=192.168.1.5, lip=::1, pip=::1, mpid=8665, secured Jack Bates

[Dovecot] Difference between Indexing and Rescan in FTS
by Fred Kilbourn 18 Oct '12

18 Oct '12

I've had squat running on dovecot 2.0 and have been updating all users mailbox indexes nighty via cron with this command: doveadm -v search -A text xyzzyx I've just updated to 2.1 and I'm migrating to lucene indexes, but reading the documentation I'm having a hard time understanding the semantic differences between indexing and rescanning. If I were to continue to run an all user all mailbox index every night, would that be appropriate? Would running this every night avoid the need to ever rescan? Should I run rescan instead of index? Should I run both rescan and index? In which order? Best Regards, FredK

I am using Open Xchange community edition on top of dovecot and tha tis showing the 200MB limit, if I change it in the dovecot.conf the change is reflected in open xchange, but can't figure out how to change for 1 user.

[Dovecot] Dsync clustering

I have not seen mention of using dsync for clustering Dovecot in some time on the mailing list, but I believe Timo was going to write a wiki page when v2.2 became more mature. Does this documentation exist yet, or are there any resources on what dsync replication is capable of at this point (looking on the wiki and google didn't reveal much)? Thank in advance.

Easy enough to test. It's non-RFC compliant as one poster points out, so unless you got a good reason to do this like lots of zombie pop3 processes, leave it alone.

[Dovecot] Dovecot sieve and duplicate email subjects
by Benjamin Thomas 17 Oct '12

17 Oct '12

Hi, I'm running a small email server with the help of iRedMail. I can manage sieve scripts from the Rouncube web interface or manually inside the user's personal sieve folder. I have an email account setup to receive automated tasks. Some of these "alerts" occur too often and they have the same subject line, but different senders. This is the rule I am currently using: ##CODE START## # rule:[AutoAlerts] if anyof ( header :matches "Subject" "AutoAlert Type1*", header :matches "Subject" "AutoAlert Type2*", header :matches "Subject" "AutoAlert Type3*" ) { fileinto "INBOX.AutoAlerts"; stop; } ##CODE END## I was wondering if it's possible to gracefully handle duplicate subjects lines (within a given time frame) with sieve filters ? Ideally, I would like the first email of the day with subject ""AutoAlert Type1..." to get moved to the subfolder given above. Subsequent "duplicate" emails would then go into a "duplicate" subfolder. Is this possible with sieve filters ? I could not find anything striking me as obvious while reading the page http://wiki.dovecot.org/LDA/Sieve. Thanks very much for your input.

[Dovecot] Dovecot failed logins delay all logins
by Dominic Malolepszy 17 Oct '12

17 Oct '12

Hi all, I have observed with my Dovecot setup that unique failed logins cause legitimate correct logins to be slowed. I am running two servers, each with two Dovecot instances, a Proxy with Director, and a backend Dovecot. I suspect that the backend instance is throttling connections from the same IP, and because I am running a Proxy, the backend will only see either of the two server IPs. I confirmed this by directly connecting to the backend, to bypass the proxy and rule it. I initiated dozens of unique failed logins from one IP and separately attempted to login from the same IP, and experienced an extended delay during login. At the same time a login from a different IP suceeded imediately. I see nothing in the logs suggesting some sort of process limits were exceeded, however I do see the following proc title for the backend auth process: "dovecot/auth [7 wait, 0 passdb, 0 userdb]" I have increased the mail_max_userip_connections to a very large value however I believe that setting is a per username/ip limit. Is there any sort of setting in Dovecot that I can configure that stops this authentication throttling per IP? Below is the configuration of the backend Dovecot instance. # 2.1.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.5.2.el6.x86_64 x86_64 Red Hat Enterprise Linux Server release 6.3 (Santiago) auth_cache_negative_ttl = 3 secs auth_cache_size = 100 M auth_cache_ttl = 10 mins auth_default_realm = example.com auth_failure_delay = 5 secs auth_mechanisms = plain login auth_verbose_passwords = sha1 auth_worker_max_count = 25 base_dir = /var/run/dovecot/ disable_plaintext_auth = no first_valid_gid = 12 first_valid_uid = 8 last_valid_gid = 12 last_valid_uid = 8 login_greeting = Hello there. login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c mail_fsync = always mail_gid = mail mail_location = maildir:%h/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = " stats" mail_uid = mail mmap_disable = yes namespace { inbox = yes location = maildir:%h/Maildir prefix = INBOX. separator = . } passdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } protocols = pop3 imap service auth { unix_listener auth-userdb { group = mail mode = 0660 user = mail } } service imap-login { inet_listener imap { address = 0.0.0.0 port = 9143 } process_min_avail = 5 service_count = 0 vsz_limit = 256 M } service imap { process_limit = 1000 vsz_limit = 256 M } service pop3-login { inet_listener pop3 { address = 0.0.0.0 port = 9110 } process_min_avail = 5 service_count = 0 vsz_limit = 256 M } service pop3 { process_limit = 1000 vsz_limit = 256 M } service stats { fifo_listener stats-mail { mode = 0600 user = mail } inet_listener { address = 127.0.0.1 port = 24242 } } ssl = no stats_memory_limit = 64 M userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } verbose_proctitle = yes protocol imap { imap_logout_format = bytes_read=%i bytes_send=%o mail_max_userip_connections = 1000 mail_plugins = " stats " } protocol pop3 { mail_max_userip_connections = 1000 } Dominic

[Dovecot] Problem with quota update in dovecot 1.2

Hi A have a problem with quota2 table, working under postfixadmin. When I login into imap server with thunderbird client everything works fine, quota is update when i receive a message, but when I move message to trash or any other folder value for messages field in table quota2 increases +1 instead decreases or have still this same value. Only if I close my imap client value descending -2. I wish to table quota2 will be updated immediately after any operation on inbox. Is there any mistake in my configuration?

[Dovecot] Plugin hooks in login process
by Simone Lazzaris 16 Oct '12

16 Oct '12

Hi all; I've setup dovecot (2.1.10) in a cluster configuration. We have two servers acting as frontend which authenticates users and proxy them to other two servers which handles the "real" work. Users credentials are on a mysql cluster; we have one master, in which read/write queries are processed, and many replicated slave, which process read-only queries. The frontend servers reads users credentials from the read-only mysql slaves. I'd like to execute a query once the client is verified to update the last login data. Right now, that query is executed on the backend servers, via a post-login service: protocols = imap service imap-postlogin { executable = script-login /usr/local/etc/dovecot/postlogin.sh unix_listener imap-postlogin { group = vchkpw mode = 0600 user = vpopmail } } service imap { executable = imap imap-postlogin process_limit = 2048 } Problem is, if I execute the update on the backend, I miss the information regarding the original IP, as I only see the IP of the proxies. I haven't been able to launch the postlogin service on the frontend, so I figured that I can try to write a plugin - that also seems to me the cleanest solution. Looking in the dovecot source code, I noticed that there aren't any hooks in the execution path used by the proxies; I am missing something ? I am the only one missing the presence of this hooks in the auth/proxy process ? I've also thought of a workaround for this problem. One way is to monitor the dovecot logs on the frontend and execute the update asyncronously. One other way is to query directly the main mysql server of the cluster and adjust the query making it call a stored procedure that updates the information in case of successful login. But I'd really prefer to create a plugin, that I'd be willing to share. I attach the configuration of the servers (front and back) generated via postfix -n. Thanks in advance for any help. -- Simone Lazzaris | Responsabile aree datacenter e VoIP Interactive Network srl | via Roggia Vignola 9, 24047 Treviglio (BG) Tel. 0363 1970352 | Fax 0363.1971971 | www.interactive.eu

[Dovecot] Dovecot deliver Segmentation fault when arrive the first message
by Alessio Cecchi 16 Oct '12

16 Oct '12

Hi, I have found this strange problem. I'm working with Debian 6, dovecot 2.1.9 and vpopmail-auth. LDA is configured and works fine but the problem is when the first message arrive "dovecot-lda" return a "Segmentation fault", the message is written to the user's Mailbox but the message remains, also, in the queue of qmail (deferral: Segmentation_fault/) and at the second attempt is delivered fine. If disable ACL (acl and imap_acl from mail_plugins) in dovecot.conf "Segmentation fault" go away. Moreover, without ACL at the first delivery folders like Sent, Drafts, Trash, Spam appear immediately. An example, new user: root@demo-vpop ~ # tree /home/vpopmail/domains/qboxdns.it/cecchi2/Maildir/ -a /home/vpopmail/domains/qboxdns.it/cecchi2/Maildir/ ├── cur ├── maildirsize ├── new └── tmp

[Dovecot] Search for substring in header?
by Dave Abrahams 16 Oct '12

16 Oct '12

Hi, According to the IMAP spec (http://tools.ietf.org/html/rfc2060#page-37) if I do a search for "TO isocpp.org" it should find all the messages whose To: field contains the string "isocpp.org", but dovecot is returning me an empty list. However, a search for "TO tm(a)isocpp.org" produces a long list of messages. What am I doing wrong?

[Dovecot] [BUG] Lucene plugin breaks header substring search
by Dave Abrahams 16 Oct '12

16 Oct '12

According to the IMAP spec if I do a search for "TO isocpp.org" it should find all the messages whose To: field contains the string "isocpp.org", but dovecot is returning me an empty list. However, a search for "TO tm(a)isocpp.org" produces a long list of messages. This behavior is present if I *even load* the lucene fts plugin.

Re: [Dovecot] per-user quotas
by David Mehler 16 Oct '12

16 Oct '12

Hello, Thanks for your replies so far. Still having issues with per-user quotas. To my Mysql virtual_users table I've added a column quota_kb and for a test user I've added in a value of 250000 going for a 250 megabyte quota. I've tried various sql queries they're returning empty sets not pulling out the information needed. Thanks. Dave.

I don't know if this was supposed to have changed with dovecot2, but http://wiki.dovecot.org/Plugins/FTS shows fts = squat solr so, since I have the lucene plugin—"fts = lucene" works by itself—I tried fts = squat lucene but: $ doveadm index '*' doveadm(dave): Error: fts: Failed to initialize backend 'squat lucene': Unknown backend So, is that syntax obsolete, is the wiki wrong, or am I doing something wrong? -- Dave Abrahams BoostPro Computing Software Development Training http://www.boostpro.com Clang/LLVM/EDG Compilers C++ Boost

[Dovecot] POP UIDL
by simon.buongiorno＠gmail.com 16 Oct '12

16 Oct '12

Hi I run a small mail server with Dovecot and postfix. Several of the accounts are popped by an external email provide I use, mostly out habit and also for a bit of redundancy. I have no details on that external server except that it uses exim. Lately, it's been repopping mail from accounts (mail is left on the server so I can use IMAP) at fairly frequent, but undetermined, intervals. Before I take it to them, I want to be sure it's not an error on my side. How can I be sure Dovecot does not have a problem with the UIDL list causing this external server to repop the mail? For the record, I'm not inclined to think it's a Dovecot issue, but since that's the bit I can fix, I'd like to be sure. Cheers Simon

[Dovecot] Dovecot Hangs while mutile users download mail for same account using pop3
by Robert JR 16 Oct '12

Hello, I have a weird problem in dovecot, Dovecot Hangs while multiple users download mail for same account using pop3 Three persons use 1 same email , and three of them use outlook express to check That specific mail .. Also some times one of the three users check the mail for this Account using imap (squirrel mail) And here comes the problem. suddenly all the three users are unable to check the mail And when the outlook express connect to the pop3 server, they are unable to disconnect And the outlook express keep asking "the server is not responding for 60 mins would you like to wait ? i checked /var/log/maillog, i can see the following errors dovecot: pop3(sales): Disconnected: Storage error during logout. to=<sales(a)domain.com>, orig_to=<sales(a)domain.,com>, relay=local, delay=357, delays=338/0.01/0/19, dsn=4.2.0, status=deferred (cannot update mailbox /var/mail/sales for user sales. unable to lock for exclusive access: Resource temporarily unavailable) When i used lsof | grep sales pop3 4278 sales 10u REG 8,3 22897673 12615705 /var/spool/mail/sales i went to /home/sales/mail/.imap/INBOX , but i didnot find any lock files -rw------- 1 sales sales 944 Oct 7 13:35 dovecot.index -rw------- 1 sales sales 49152 Oct 7 16:57 dovecot.index.cache -rw------- 1 sales sales 14044 Oct 7 16:57 dovecot.index.log 1- So what is exactly the problem? is the problem that three users are checking the same exact mail ? 2- is the problem that 2 users checking mail using pop3 and the third one checking it using imap insame time ? 3- is dovecot locking the inbox file while one of the users getting the mail ? 4- What is the cause of the problem ? Please help Regards Robert JR

[Dovecot] Where'd the Mail Go?
by John Reddy 16 Oct '12

16 Oct '12

Hi; I ran this: echo "Hello me" | mail -s "Dovecot test" $USER then created a bash script: for mbox in /var/mail/$USER /var/spool/mail/$USER ~/mbox ~/mail/* ~/*; do grep -q "Dovecot test" $mbox && echo "mbox: $mbox" done grep -q "Dovecot test" ~/Maildir/new/* 2>/dev/null && echo "Maildir: ~/Maildir" and ran it but couldn't find where the mail went. I checked /var/mail/my_user_name and it wasn't there, either. How do I find it? TIA, John

[Dovecot] Advanced dovecot tricks - spam review/release
by Marc Perkel 16 Oct '12

16 Oct '12

Hi, I'm looking for some advice to do a really advanced trick with Dovecot. I'm not sure if this can be done. I need to describe first. I have a spam filtering company that does front end spam filtering. (Junk Email Filter) I want to add a system where I store a copy of spam on a server and make it available to the customer to review and maybe resent on false positives. I know I could do something simple where I deliver all spam to a domain account and make it available to an administrator. Then if it's a false positive they would drag the message to a "resend" folder. I'll have something the checks the folder one a minute to pick up and resend. However What would be very cool is delivering the spam to individual accounts. So a user who logs in individually can see their own spam. But the admin for the domain would be able to see all users. Maybe the users would appear as folders? Then a master account (me) would be able to log in and see all the domains as folders and the users as folders inside the domains? One thing I can do is deliver the spam to 3 different places so it's visible on all levels. I'm just wondering if anyone out there has any ideas about that. And I'll need an authentication system.

HELP! I have installed sendmail, dovecot, and squirrel mail. The squirrel mail portion of it works just fine, but I would like to have Mozilla Thunderbird as a client. Whenever I try and connect to the server it says "Thunderbird failed to find the settings for your email account." We do have an MX record in DNS pointing to our server. We are using Ubuntu 12.0.4.1, and have Dovecot 2.2.6 sendmail version 8.14.4-2ubuntu2 We are doing this for a class project and it is due by Tuesday 10/16/2012.. Thanks, Justin

[Dovecot] dsync ignores ssh-agent
by Mark Hills 13 Oct '12

13 Oct '12

I use IMAP over SSH, in pre-auth. I wanted to use dsync to offline mail to my laptop. dsync v2.1.10 would always ask for my SSH key/passphrase, ignoring ssh-agent. The culprit is the env_clean() in the stack below. Reading the source, I saw DOVECOT_PRESERVE_ENVS. When used as follows in my script it enables dsync to find my ssh-agent: export DOVECOT_PRESERVE_ENVS="SSH_AGENT_PID SSH_AUTH_SOCK" dsync mirror ssh imap.example.com /home/mark/opt/dovecot/bin/dsync and it now works without asking for password every time. I'm posting here so that anyone else googling for the same problem will hopefully find this, as I couldn't find anything about this in the docs. Also I'm interested in why dsync so aggressively cleans the environment; I tried a naive removal of env_clean() but this breaks basic functions. With this dsync is working very well for offline mail -- combined with alpine and a local exim for the outbound queue :) Thanks -- Mark Breakpoint 2, env_clean () at env-util.c:59 59 if (clearenv() < 0) (gdb) bt #0 env_clean () at env-util.c:59 #1 0xb7df10fc in master_service_env_clean () at master-service.c:454 #2 0xb7df26d4 in master_service_exec_config (service=0x809e7d0, input=0xbffff7e4) at master-service-settings.c:103 #3 0xb7df29be in config_exec_fallback (service=0x809e7d0, input=0xbffff7e4) at master-service-settings.c:153 #4 0xb7df2b65 in master_service_open_config (service=0x809e7d0, input=0xbffff7e4, path_r=0xbffff780, error_r=0xbffff7d8) at master-service-settings.c:206 #5 0xb7df3130 in master_service_settings_read (service=0x809e7d0, input=0xbffff7e4, output_r=0xbffff7dc, error_r=0xbffff7d8) at master-service-settings.c:345 #6 0x0805c672 in doveadm_read_settings () at doveadm.c:275 #7 0x0805c7d6 in main (argc=5, argv=0x809e1c0) at doveadm.c:342

[Dovecot] INBOX.INBOX.Sent causes problems in 2.0
by Christoph Bußenius 12 Oct '12

12 Oct '12

Hi, we have our namespace rooted at "INBOX.". Sometimes, users have folders like "INBOX.INBOX.Sent" or "INBOX.INBOX.INBOX.Sent". I do not know why these folders are created; I suspect it is due to buggy MUAs. If a mailbox like INBOX.INBOX.Sent exists, then in some cases Dovecot counts all messages in INBOX twice. This behavior can be demonstrated as follows: 1) Create a folder named "INBOX.INBOX.Sent" (using the IMAP CREATE command) 2) Save a message to "INBOX" (in my example the message is 7 MB) 3) dovecot-quota contains: priv/quota/storage 7129025 priv/quota/messages 1 4) doveadm quota recalc -u user1 5) Now dovecot-quota contains priv/quota/storage 14258050 priv/quota/messages 2 I.e. the user will experience that his quota fills up very fast. "doveadm -f flow fetch -u user1 'mailbox guid' ALL" prints: mailbox=INBOX guid=040ce73645177850497d000040c59ffc mailbox=INBOX guid=040ce73645177850497d000040c59ffc However, "doveadm -f flow fetch -u user1 'mailbox guid' mailbox INBOX" prints the message only once: mailbox=INBOX guid=040ce73645177850497d000040c59ffc How can we prevent this kind of confusion? What I'd like most is prevent the creation of these weird folders. Most MUAs have problems listing them properly, especially if both "INBOX.Sent" and "INBOX.INBOX.Sent" exist. Dovecot 2.1 does not seem to count anything twice. Cheers, Christoph Config: # 2.0.21: /usr/local/dovecot/etc/dovecot/dovecot.conf doveconf: Warning: service auth { client_limit=4096 } is lower than required under max. load (6224) # OS: Linux 2.6.32-42-server x86_64 Ubuntu 10.04.4 LTS disable_plaintext_auth = no mail_gid = vmail mail_location = mdbox:~/mail mail_plugins = quota mail_uid = vmail namespace default { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = scheme=CRYPT username_format=%u /usr/local/dovecot/etc/dovecot/users driver = passwd-file } plugin { quota = dict:ROOT::file:%h/dovecot-quota quota_rule = *:storage=5G } protocols = imap pop3 service auth { unix_listener auth-userdb { group = vmail mode = 0660 } } service imap { process_limit = 5000 } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /usr/local/dovecot/etc/dovecot/users driver = passwd-file } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_max_userip_connections = 20 mail_plugins = quota imap_quota } And the contents of the "users" file: user1:{plain}secret:::user1:/mail/users/user1:: -- Christoph Bußenius Rechnerbetriebsgruppe der Fakultäten Informatik und Mathematik Technische Universität München +49 89-289-18519 <> Raum 00.05.040 <> Boltzmannstr. 3 <> Garching

[Dovecot] [PATCH] dovadm plugins underlinking
by Natanael Copa 12 Oct '12

12 Oct '12

Hi, Running doveadm on Alpine Linux will show various underlinking errors: /usr/bin/doveadm: symbol 'acl_user_module': can't resolve symbol in lib '/usr/lib/dovecot/doveadm/lib10_doveadm_acl_plugin.so'. /usr/bin/doveadm: symbol 'acl_identifier_parse': can't resolve symbol in lib '/usr/lib/dovecot/doveadm/lib10_doveadm_acl_plugin.so'. ... (complete list is found here: http://bugs.alpinelinux.org/issues/1274) I understand that those are "harmless" (at least as long as you dont use those plugins), and even if some dynamic linkers are forgiving, the doveadm plugin modules are technically underlinked.

[Dovecot] imap proxy setup - "killed with signal 11"
by btb 12 Oct '12

12 Oct '12

hi- i'm setting up an imap proxy in front of a novell groupwise server. it seems to so far be partially working, but dovecot is having trouble in certain cases. i expect that it's ultimately due to what i believe is a very poor implementation of imap provided by groupwise [at least based on other experiences in the past] - but that's a big part of why i'd like to have dovecot in between it and clients. below is information collected during starting of dovecot, opening/initial connection from a client [os x mail.app], closing of the client, and stopping of dovecot. os is ubuntu 12.10 development/beta, dovecot is 2.1.7 courtesy of ubuntu's packages. log entries: Oct 11 13:24:33 halo dovecot: master: Dovecot v2.1.7 starting up Oct 11 13:24:49 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14171, TLS, session=<iHgu2cvLlwAKRChu> Oct 11 13:24:50 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14174, TLS, session=<t1E/2cvLoQAKRChu> Oct 11 13:24:51 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14176, TLS, session=<OZlM2cvLqgAKRChu> Oct 11 13:24:51 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14178, TLS, session=<d3NU2cvLsQAKRChu> Oct 11 13:24:51 halo dovecot: imap(jdoe): Connection closed in=16 out=350 Oct 11 13:24:52 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14180, TLS, session=<oxNa2cvLtAAKRChu> Oct 11 13:24:52 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:24:52 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14176 killed with signal 11 (core dumped) Oct 11 13:24:57 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:24:57 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14178 killed with signal 11 (core dumped) Oct 11 13:24:57 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14182, TLS, session=<FUCv2cvLuAAKRChu> Oct 11 13:24:58 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:24:58 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14180 killed with signal 11 (core dumped) Oct 11 13:25:03 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:25:03 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14182 killed with signal 11 (core dumped) Oct 11 13:25:03 halo dovecot: imap-login: Login: user=<jdoe>, method=PLAIN, rip=10.68.40.110, lip=10.59.1.53, mpid=14184, TLS, session=<DQkF2svLuwAKRChu> Oct 11 13:25:03 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:25:03 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14184 killed with signal 11 (core dumped) Oct 11 13:25:09 halo dovecot: imap(jdoe): Error: imapc: Mailbox 'Trash' state corrupted: Expunged message reappeared in session (uid=6282 < next_uid=6283) Oct 11 13:25:09 halo dovecot: imap(jdoe): Fatal: master: service(imap): child 14174 killed with signal 11 (core dumped) [repeats] Oct 11 13:25:27 halo dovecot: dns-client: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: dns-client: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: master: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: auth: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: config: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: ssl-params: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: anvil: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) Oct 11 13:25:27 halo dovecot: log: Warning: Killed with signal 15 (by pid=1 uid=0 code=kill) gdb backtrace: ~ >gdb /usr/lib/dovecot/imap /var/cache/imapproxy/jdoe/core GNU gdb (GDB) 7.5-ubuntu Copyright (C) 2012 Free Software Foundation, Inc.

[Dovecot] per-user quotas
by David Mehler 12 Oct '12

12 Oct '12

Hello, I've got quotas set up on an all-user basis on my system, it's a Postfix, Dovecot, Mysql virtual users setup. Currently I have each user getting a 1GB quota with these settings in 90-quota.conf: plugin { quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M } plugin { quota = maildir:User quota } While this works it's not what I want for all users. Say I add a virtual user called user1 to the mysql database but he's a test user and I only want that user to have 25 megabytes of storage, reading the wiki on quotas per-user items such as for example in a database overrides the global items above, is this right? If so, I'm hoping I'm not going to have to redo my entire user database, some users will have per-user quotas while I'll let others have the global quota. Thanks. Dave.

[Dovecot] Feature Request
by Marc Perkel 12 Oct '12

12 Oct '12

It would be handy (for me) if there were a userdb where a directory structure defined the db. userdb stat { mail_location=maildir:/fakedir/%d/%n:INBOX=/email/%d/%n:LAYOUT=fs } userdb stat { mail_location=maildir:/email/%d/%n:INBOX=/email/%d/%n:LAYOUT=fs } The idea being that if the first directory doesn't exist then it will try the second one.

I'm authenticating with this: userdb { driver = sql args = /etc/dovecot/master-combined-sql.conf } Default mail location: mail_location = maildir:/fakedir/%d/%n:INBOX=/email/%d/%n:LAYOUT=fs However - what I'd like to do is if the mail location doesn't exist then I want to try a second mail location: mail_location = maildir:/email/%d/%n:INBOX=/email/%d/%n:LAYOUT=fs How do I do that? Thanks in advance
