[Dovecot] Plugin architecture
by Philipp Brüll 06 Feb '14

06 Feb '14

Hi, I'm currently developing a scrambler plugin which should be used to store the mails encrypted on the disk. It uses a special ostream for encryption and an istream for decryption. The idea is, that if a mail arrives via LMTP it goes through the ostream and is written encrypted to disk. If an mail is accessed via IMAP, the istream is used to decrypt the data from disk. That all works fine, but if I add the zlib plugin it all gets mixed up. For some reason, the lmtp process tries to read something from disk using the chain of istreams. That behaviour is a little bit bizzare to me, because my understanding is, that the zlib plugin at this point should only write (compressed) data to disk. Why is the istream used here? And what is read? If I remove zlib from the configuration again, it all works as expected. The dovecot version is 2.1.17. Best regards, Philipp

[Dovecot] Trying to get Dovecot Director Proxying working
by Murray Trainer 06 Feb '14

06 Feb '14

Hi All, Firstly, thanks for all the really helpful responses to my previous questions "Architecture for large Dovecot cluster" and "Sizing MTA servers". I am now trying to get a Dovecot director proxy working with a single backend mail server. When I try to connect to the dovecot proxy on the pop3 and imap ports I get connection refused. I want the authentication to be on the backend mail server initially. I am not sure if I am missing something? More info below... Thanks Murray # doveadm director status mail server ip vhosts users 27.54.95.41 100 0 # doveadm director map doveadm(root): Error: userdb list: Disconnected unexpectedly doveadm(root): Error: user listing failed user mail server ip expire time # doveadm fetch -A user ALL doveadm(root): Error: userdb list: Disconnected unexpectedly doveadm: Error: Failed to iterate through some users # doveconf -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.1 auth_cache_size = 32 M auth_cache_ttl = 2 hours auth_debug = yes auth_verbose = yes base_dir = /var/run/dovecot/ director_mail_servers = 27.54.95.41 director_servers = 27.54.95.37 disable_plaintext_auth = no mail_debug = yes passdb { args = nopassword=y proxy=y driver = static } service auth { unix_listener auth-userdb { mode = 0666 user = dovecot } } service director { fifo_listener login/proxy-notify { mode = 0666 } inet_listener { port = 9090 } unix_listener director-userdb { mode = 0600 } unix_listener login/director { mode = 0666 } } service imap-login { executable = imap-login director } service ipc { unix_listener ipc { user = dovecot } } service pop3-login { executable = pop3-login director } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = uid=dovenull gid=dovenull home=/var/run/dovecot/empty driver = static }

[Dovecot] LMTP troubles
by Phillip Odam 06 Feb '14

06 Feb '14

Background: Dovecot: v 2.0.9 OS: AWS Linux (derived from CentOS) At this stage I've avoided upgrading to a newer version of Dovecot as version 2.0.9 is what AWS Linux provides and I'd like to be able to run a regular AWS Linux installation if I can. As opposed to pulling newer versions of dovecot from other repositories or building from source, since the odds are this issue is not a bug in dovecot. I've just tried setting up the LMTP service and eventually uncovered that that the greeting the server responds with straight after connecting isn't being returned. This must be a configuration mistake on my behalf but I just haven't been able to figure it out yet. I haven't had LMTP configured for awhile but I'm sure I've had it all in place and don't recall any issue like this. I've followed the detail here http://wiki2.dovecot.org/LMTP, in particular # add lmtp to protocols, otherwise its listeners are ignored protocols = imap pop3 lmtp service lmtp { inet_listener lmtp { address = 192.168.0.24 127.0.0.1 ::1 port = 24 } unix_listener lmtp { #mode = 0666 } } What's also interesting, using telnet my first attempt to connect results in the server closing the connection immediately and then a second attempt to connect results in an established connection but no response from the server so that then the LMTP client knows it's all good to begin issuing commands. I have no idea about the architecture of dovecot and the LMTP service but it's as if dovecot has successfully bound to the port allocated for LMTP* but the the LMTP service has either not started or dovecot doesn't know which service to pass the connection on to. * - dovecot has definitely bound to the port (localhost:24) as netstat clearly shows this. I've tried enabling debug logging per the details here http://wiki2.dovecot.org/Logging and checked that I'm looking at all the logs I need to be using doveadm log find but not seeing any information that helps. At the moment I know I'm light on necessary detail for anyone to help but I thought I'd try in case anyone has seen this before and is able to tell me I've missed X and Y. I'm planning on setting up a clean environment to sort this issue out and if needed will follow up here with more detail and the final solution/s. Thanks Phillip

[Dovecot] mime support for pigeonhole
by Tim Dickson 06 Feb '14

06 Feb '14

is there any chance of rfc5703 (mime support/extension) being added to pigeonhole? I am trying to filter mail with .exe and .zip attachments, to no success. I have tried *header :contains "x-attached" [".zip", ".exe"] *but emails i'm getting don't have x-attached. a sample snippet is below. Subject: testa1 Content-Type: multipart/mixed; boundary="------------020304040002050407030900" This is a multi-part message in MIME format. --------------020304040002050407030900 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit this has a compressed file added a1 --------------020304040002050407030900 Content-Type: application/x-zip-compressed; name="pinglog.zip" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="pinglog.zip" I have tried *header :contains ["Content-Type","name","filename"] ["application/x-zip-compressed",".zip",".exe"]* but that doesn't work either. I can't use body because that doesn't include the mime headers, so the only way I can see is to use mime (aka rfc5703) I am using dovecot 2.1.8 with pigeonhole 0.3.3 (and am about to use dovecot 2.2.9 with pigeonhole 0.4.2 on another server) If I'm just missing the point, or there is already support, please point me in the right direction.

[Dovecot] Mail location security
by Roman Gelfand 06 Feb '14

06 Feb '14

I am not sure I understood this issue correctly... When using maildir with ie ldap. Suppose ldap attribute settings say gid 8 and uid 999, Those are the permissions for every email address. If so, someone who has access to one email user on the server, has access to all. If this is so, is using mailbox instead of maildir resolve this problem? Thanks in advance

[Dovecot] userdb section not recognized in dovecot.conf. Help?
by CypherPunk 06 Feb '14

06 Feb '14

I'm following a tutorial[1] on how to configure dovecot and the tutorial says to insert the following configuration options into the dovecot.conf file: disable_plaintext_auth = no mail_privileged_group = mail mail_location = mbox:~/mail:INBOX=/var/mail/%u userdb { driver = passwd } This seems to have worked for a lot of others using this tutorial but not for me. When I try to start dovecot, I am told that the section at userdb is an unknown section type. I've spent the last few hours on Google searching this out and I've gotten conflicting answers that don't make sense. Is this the proper way to use the userdb directive? For information, I've also tried userdb{ driver = passwd-file } and that didn't work either. So I'm assuming that perhaps userdb is deprecated somehow but I don't know what to replace it with. Can someone point me in the right direction? Many Thanks! CypherPunk [1] https://www.digitalocean.com/community/articles/how-to-set-up-a-postfix-e-m…

[Dovecot] Debian Wheezy-Backports - Dovecot (1:2.2.9-1~bpo70+1) missing xz compression support?
by T.B. 05 Feb '14

05 Feb '14

Hallo Everyone, since some days a new dovecot version is available in Debian "wheezy-backports": (1:2.2.9-1~bpo70+1) wheezy-backports As described in http://wiki2.dovecot.org/Plugins/Zlib and http://www.dovecot.org/doc/NEWS-2.2 "xz"-compression is available since Dovecot version 2.2.9. Today I tried to convert my mailboxes with the new xz compression. Therfore I changed my config as follows: /etc/dovecot/conf.d/10-mail.conf: # Space separated list of plugins to load for all services. Plugins specific to IMAP, LDA, etc. are added to this list in their own .conf files. mail_plugins = zlib acl fts fts_solr /etc/dovecot/conf.d/90-plugin.conf: # Enable these only if you want compression while saving: zlib_save_level = 9 # 1..9 zlib_save = xz # gz or bz2 or xy Now I tried to convert my mailboxes - but somehow, something goes wrong: root@SERVER:/# dovecot --version 2.2.9 root@SERVER:/# dsync mirror mdbox:/srv/converted_vmail/ doveadm(root): Error: zlib_save: Support not compiled in for handler: xz dsync(root): Error: zlib_save: Support not compiled in for handler: xz Where is the failure? Did the packet maintainer forget to activate xz? I can't find anything xz related in the debian package changelog: http://metadata.ftp-master.debian.org/changelogs//main/d/dovecot/dovecot_2.… Should I contact the Debian packet maintainer? http://packages.qa.debian.org/d/dovecot.html Best regards T.B.

[Dovecot] How to archive mails on different server
by Anant Saraswat 05 Feb '14

05 Feb '14

Hi Guys, I want to make some new changes to my exim mail server So if any user archive his/her mail they will save on any other server not on Exim server , and whenever user want to search for any old mail he will go to archive folder and can search it from there.... So basically i want to setup a diffrent server for archiving and want to connect it to my Exim server. So whevever user archive his/her mail it will autometically save to diffrent server. So is it possible using any plugin , or something else . I am using Roundcube,Exim 4.72, Dovecot(LMTP). Regards, Anant Saraswat

Hi there, I've started work on a side project that I've been long wanting to do; better HTML archives of email. https://github.com/kaihendry/imap2json I'm just designing the JSON schema atm, and I thought it would be good to get your feedback (Esp Timo) before I make a horrible mistake. https://github.com/kaihendry/imap2json/blob/master/JSON-design.mdwn Is it a good idea to base the id of a converation by the sha1sum of the first message for example? Any other tips or words of encouragement would be great. Kind regards,

[Dovecot] Applying a DNS RBL to deny authentication?
by Marc Perkel 05 Feb '14

05 Feb '14

Hope to get some attention about this idea to reduce hacking passwords. Here is a list of about 700,000 IP addresses that are hacking passwords through SMTP AUTH http://ipadmin.junkemailfilter.com/auth-hack.txt This is a list of IP addresses that attempted to authenticate against my fake AUTH advertizing on servers with no authentication. We do front end spam filtering for thousands of domains and I decided to advertize authentication where there is none and I accept and blackhole all authenticated email to those servers. I have harvested the IP addresses in this list that is available through an RBL. It seems to me that a nice dovecot feature would be the ability to do a black list check against IP addresses connecting and deny access if listed. Thoughts?

[Dovecot] dsync backup; compressed to uncompressed
by Michael Smith (DF) 05 Feb '14

I need to backup some of the mailboxes on our system. We are currently using mdbox with zlib compression plugin. The backups need to be maildir without compression. How can I accomplish this using dsync? The following just causes each msg file in maildir to be compressed as well. dsync -f -u user1 backup maildir:/var/tmp/user1 While this just causes the dsync to fail while spewing a bunch of errors because it can no longer read the compressed mdbox files. dsync -f -u user1 -o mail_plugins= backup maildir:/var/tmp/user1 # doveconf -n # 2.2.4: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.19.1.el6.x86_64 x86_64 CentOS release 6.3 (Final) auth_debug = yes auth_debug_passwords = yes auth_default_realm = domain1.net auth_master_user_separator = * auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = plain debug_log_path = /var/log/dovecot-debug.log disable_plaintext_auth = no dotlock_use_excl = no lda_mailbox_autocreate = yes lock_method = dotlock mail_access_groups = mail mail_debug = yes mail_fsync = always mail_location = mdbox:~/mail:INDEX=~/index mail_plugins = quota zlib mail_privileged_group = mail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date mbox_read_locks = dotlock mbox_write_locks = dotlock mdbox_rotate_interval = 1 weeks mdbox_rotate_size = 20 M mmap_disable = yes namespace { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-sql-master.conf.ext driver = sql master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { autosubscribe = Trash autosubscribe2 = Junk autosubscribe3 = Drafts autosubscribe4 = Sent autosubscribe5 = INBOX mail_max_userip_connections = 10 managesieve_max_line_length = 65536 quota = dict:User quota::file:%h/dovecot.quota quota2_rule = Trash:storage=+10%% quota3_rule = Junk:storage=+20%% quota_rule = *:storage=100M:messages=100000 recipient_delimiter = + sieve_before = /var/opt/mail/global.sieve/ zlib_save = gz zlib_save_level = 9 } pop3_reuse_xuidl = yes protocols = imap pop3 sieve lmtp service auth { inet_listener auth { port = 113 } unix_listener auth-userdb { user = nobody } } service lmtp { inet_listener lmtp { port = 24 } process_min_avail = 10 service_count = 1 } service managesieve-login { inet_listener sieve { port = 4190 } process_min_avail = 0 service_count = 1 vsz_limit = 64 M } ssl = no ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lda { mail_plugins = quota zlib sieve } protocol imap { mail_plugins = quota zlib imap_quota } protocol sieve { mail_max_userip_connections = 10 mail_plugins = quota zlib managesieve_max_line_length = 65536 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 } protocol lmtp { mail_plugins = quota zlib sieve }

[Dovecot] BLF-CRYPT passwords
by KT Walrus 04 Feb '14

04 Feb '14

I’m using the Dovecot Enterprise Edition on Centos 6.5, but Blowfish password hashes don’t seem to work. What can I do to enable Blowfish hashes for passwords? Maybe I don’t have my installation configured properly? Note that I really want to use the existing Blowfish hashes in my MySQL database for Dovecot Authentication. The hashes are generated by PHP crypt() that has Blowfish support built-in. I looked at PHP’s sources, and PHP uses crypt_blowfish.c from http://www.openwall.com/crypt/. This code is in the public domain and could easily be used by Dovecot to support Blowfish passwords on all platforms (if Dovecot doesn’t already support Blowfish on all platforms). Kevin

[Dovecot] mail_log_events, but who exactly triggered events?
by Arkadiusz Miśkiewicz 04 Feb '14

04 Feb '14

Hi. mail_log_events is nice addition but how to log who exactly triggered particular event? For example 5 users from 5 IP addresses uses single imap user/mailbox. One of them deletes email and I'm logging delete related events. The only logged thing is: dovecot: imap(user): delete: box=INBOX, uid=673287, msgid=<some@thing>, size=1230 which tells me nothing about who triggered it actually (note all 5 users were logged in at deletion time) How to solve this problem? Thanks, -- Arkadiusz Miśkiewicz, arekm / maven.pl

[Dovecot] zlib unexpected EOF
by Anand Kumria 04 Feb '14

04 Feb '14

Hi, I am seeing occasional log entries like: Feb 4 06:20:01 mail1 dovecot: imap(user(a)example.com): Error: read(<imap client>) failed: zlib.read(<imap client>): unexpected EOF at 894774 Feb 4 06:20:01 mail1 dovecot: imap(user(a)example.com): Disconnected in APPEND (1 msgs, 201 secs, 0/5180550 bytes) in=894774 out=643701 I've been able to correlate this to users - using Thunderbird - complaining that they have been unable to "send email". Is the problem on the Dovecot side, their side or something else? If on the Dovecot any pointers and what I should look at? Thanks, Anand

[Dovecot] Dovecot2 + Quota
by drum.lucas＠gmail.com 04 Feb '14

Hello! I need to configure Quota on Roundcubemail with Dovecot2. So, I did: 90-quota.conf: # SQL backend: quota = dict:User quota::proxy::sqlquota quota_rule = *:storage=20M:messages=1000 } dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } OK, works! but, My webmail shows me 20M of quota. But on my Postfixadmin I configured 200M. How can I fix this? Att; *Lucas Possamai* http://about.me/lucaspossamai https://www.digitalocean.com/?refcode=25021cb7dbdf

[Dovecot] Assertion failed with imapc after upgrading Dovecot from 2.1.7 to 2.2.9
by Sylvain 29 Jan '14

29 Jan '14

Hi ! I have an old Courier IMAP and in front of it, I have put a proxy cache with Dovecot/imapc. I use Debian Wheezy (stable) which package Dovecot in version 2.1.7. I have tested the upgrade to Debian Jessie (testing) which package Dovecot in version 2.2.9 but an assertion is thrown : dovecot: imap(xxx): Panic: file imapc-list.c: line 499 (imapc_list_delete_unused_indexes): assertion failed: (strncmp(vname, fs_list->ns->prefix, fs_list->ns->prefix_len) == 0) I have checked source code and have seen that if *imapc_list_prefix* is not set, assertion will not be "walked". It's works but special inbox aren't detected correctly in email clients. If I understand the meaning of *vname* variable, it is because our Courier IMAP send us "INBOX" which is the value of my *imapc_list_prefix* and thus, assertion is thrown.

[Dovecot] Shared mailbox ACL
by Alex Ferrara 29 Jan '14

29 Jan '14

Hi everyone, I am having some trouble with shared folders in trying to replicate how we use them with a Cyrus backend. The auth database is Samba4 active directory, so I am using an LDAP lookup to authenticate and forcing the UID and GID to be all the same. I have a post-login script that sets the group ACL, and this seems to be working fine. /mnt/mail is an NFS mount to a FreeNAS machine, and there is only one Dovecot server connecting to that NFS share. I have been able to get the inbox of the shared mailbox to appear in Thunderbird, but I would like to allow all subfolders to have the same ACLs. Is there a way to do this without having an ACL entry for each folder in the dovecot-acl file? I also cannot seem to create folders under the shared inbox. Thanks. Below is the output of /mnt/mail/acl/shared-mailboxes shared/shared-boxes/group/accounting/accounting 1 shared/shared-boxes/group/team1/team1 1 shared/shared-boxes/group/team2/team2 1 Below is the output of dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-22-pve x86_64 Debian 7.3 nfs auth_mechanisms = plain login auth_username_format = %n mail_debug = yes mail_location = maildir:/mnt/mail/mailboxes/%n/Maildir:INDEX=/var/local/dovecot-indexes/%n mail_plugins = acl mail_shared_explicit_inbox = no managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace { list = yes location = maildir:/mnt/mail/mailboxes/%%n/Maildir:INDEX=/var/local/dovecot-shared/%%n prefix = ZGroup/%%n/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_defaults_from_inbox = yes acl_shared_dict = file:/mnt/mail/acl/shared-mailboxes sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap lmtp sieve" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service imap-postlogin { executable = script-login /usr/local/bin/postlogin.py user = vmail } service imap { executable = imap imap-postlogin } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } user = vmail } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { mail_plugins = quota sieve } protocol lda { mail_plugins = quota sieve } protocol imap { mail_plugins = acl imap_acl }

Oh yes, that's right. I confused maildir format with sendmail queue files that separates header and body. There is still some similarlity for mass mailouts to the same mail domain: they will have almost identical headers +/- message IDs and a few bytes here and there, but as you say, SiS is the way to go for deduping bulky message attachments.

[Dovecot] recipient_delimiter -- feature request
by Andrew Ray 29 Jan '14

29 Jan '14

Hi, It would be nice if the recipient_delimiter configuration option supported multiple recipient delimiters as Postfix now does. e.g. now if I set: recipient_delimiter = +- in Postfix, then test-extension(a)sample.com and test+extension(a)sample.com are both recognized. But if I set: recipient_delimiter = +- in Dovecot, neither of the above are recognized and instead test+-extension(a)sample.com is valid. Well, presently this feature isn't that important to me, but I imagine it could be a source of confusion for people who are migrating from say qmail to postfix (as I am doing) and notice Postfix's cool ability to support both types of delimiters and assume Dovecot will as well (as I did).

[Dovecot] post-login scripting failing with "denied access to user" v2.1.7
by Frank 29 Jan '14

29 Jan '14

I am trying to have a default sieve rule for new mailboxes that can be edited by users using the round cube sieve plugin. It would actually be better executed when a new user is created but my postfixadmin runs on a separate machine so that's a bit tricky. The "sieve-default =" setting won't quite achieve what I want as I want users to be able to edit the default rule (to adjust SPAM level) Mail works fine before I add my post-login script to 10-master.conf ---------------------- service imap { # tell imap to do post-login lookup using a socket called "imap-postlogin" executable = imap imap-postlogin } service imap-postlogin { # all post-login scripts are executed via script-login binary executable = script-login /etc/dovecot/custom_sieve/postlogin.sh # the script process runs as the user specified here (v2.0.14+): user = mail # also tried $default_internal_user and root # this UNIX socket listener must use the same name as given to imap executable unix_listener imap-postlogin { } } After adding this setting, login fails and gives the error below. It certainly looks like a permission issue, but I have checked my script is executable and owned by vmail:vmail. The bash script executes fine as the mail user. The other possibility is that dovecot is denying access to the $HOME variable, but that seems unlikely. Nevertheless, I am stuck!

Just a guess, but I expect the difference is because NetApp de-dupes by checksumming blocks and mark whole blocks as duplicates if they have the same checksum. The message body has the same block offset in maildir (i.e. the start of a message is at byte 0), whereas mdbox might align message body anywhere in a block, so you might have 512 different block configurations for the same message. I don't know whether message alignment would be a worthwhile optimization for mdbox. Joseph Tam <jtam.home(a)gmail.com>

Everything costs less than a NetApp...except an EMC. > If anyone has any first-hand experience (or even > off-the-top-of-their-head thoughts), I'd love to hear them) Distributed filesystems give you the advantage of a single filesystem namespace with massive amounts of storage, fairly easy addition of storage space, and distributed replication to allow failure of a storage node without service interruption. Replication mitigates node failure, but not disk failure, so you still need RAID in each node. So you have RAID6 in a node and filesystem block mirroring amongst nodes. Thus storage utilization is -worse- than direct attach, CFS on SAN, or NFS head attached RAID10 and far worse than RAID6 in these 3 setups. And if using large SSD cache you'd surely use RAID6 with DAS, CFS, or NFS. You'd need half as many disk drives vs DFS. Each DFS expansion, assuming the typical model, entails the cost of a server, RAID HBA (unless using md) and disks, not strictly buying disks as with DAS, CFS/SAN, or NFS filer. Then you also need more switch ports, more power connections, greater UPS capacity due to all the CPUs, RAM, etc in the nodes. And you'll have a higher electric bill. So while a distributed filesystem storage architecture may seem less expensive it may not be. And just as one can build a DIY DFS cluster, one can also build a DIY NFS cluster instead of buying a NetApp, saving significant cash on the front end box and on disks since you'd need half as many vs a distributed filesystem architecture, though failure of one node may not be quite as graceful as with a NetApp losing a controller board. -- Stan

[Dovecot] Replication - what am I doing wrong?
by IT geek 31 27 Jan '14

27 Jan '14

Hi, I'm having issues getting replication working, and I'm not also not having much luck finding help on it. So I'm wondering... am I not asking the right questions? Or am I not providing enough information... or do we just not know how this aspect of the technology works? If it's the former, then any pointers on what questions to ask or information to provide would be very helpful. If the community genuinely doesn't know how this works then that's okay too - I will look at another solution (if one exists) and try to move on. But if I can get this working then that would be amazing as I really like Dovecot and would be gutted to move away from it. -Mark

[Dovecot] dovecot produces messages dupes after nfs problems
by Patrick Westenberg 25 Jan '14

25 Jan '14

Hi everyone, some days ago I had trouble with my NFS-Server (high delays) which caused dovecot lmtp to deliver the same message several times (up to 10x). I recognized some old/unused .nfsXXXX files in the maildirs which seemed to be index files. I deleted them and everything was fine again. However, there are still 2-3 mailboxen where mails (old and new ones) are delivered multiple times. All duplicates have no "received from" headers. Seperate lmtp log shows only one delivery. Any hint or advice what might be wrong?

[Dovecot] Architecture for large Dovecot cluster
by Murray Trainer 25 Jan '14

25 Jan '14

Hi All, I am trying to determine whether a mail server cluster based on Dovecot will be capable of supporting 500,000+ mailboxes with about 50,000 IMAP and 5000 active POP3 connections. I have looked at the Dovecot clustering suggestions here: http://blog.dovecot.org/2012/02/dovecot-clustering-with-dsync-based.html and some other Dovecot mailing list threads but I am not sure how many users such a setup will handle. I have a concern about the I/O performance of NFS in the suggested architecture above. One possible option available to us is to split up the mailboxes over multiple clusters with subsets of domains. Is there anyone out there currently running this many users on a Dovecot based mail cluster? Some suggestions or advice on the best way to go would be greatly appreciated. Thanks Murray

[Dovecot] Dovecot imap-postlogin failed
by Sayajin 24 Jan '14

24 Jan '14

*** This is 2 posts combined into one which I had asked on linuxquestions.org and never got an answer *** Hi, In short I am trying to run a bash script which will then update a mysql database with the last login date/time & last IP for each mailbox. I have searched google dead but still cant figure out what im doing wrong or if there is some issue with the centos 6 rpm's for dovecot. -- - 1st i had the default dovecot in the centos 6 repo's which is version: 2.0.9 - I read that there was an issue with the script-login binary which was fixed in version 2.0.14, so i updated dovecot to version 2.2.7. - This sadly did not fix my issue with the bash script excecuting. In my /etc/dovecot/conf.d/10-master.conf i have the following service imap { executable = imap imap-postlogin } service imap-postlogin { executable = script-login /var/www/lighttpd/mail-admin/scripts/lastLogin.sh } But when i try login i still get the same error as with the previous version: - Nov 27 14:44:36 dovecot: imap(MaIlBoX(a)DoMaIn.co.za): Error: net_connect_unix(/var/run/dovecot/imap-postlogin) failed: No such file or directory - One thing i did notice on the one site was that someone had a ls of their /var/run/dovecot directory, and in there was a binary called imap-postlogin. - But i dont have that binary anywhere on my server, with the old or new version of dovecot. Please any help would be appreciated. ===================================================== ===================================================== Ok well i tried a few other things and got it working a bit more. So the variables that i needed are now being set correctly etc, but im getting authentication errors now which I was not before. my setup in 10-master.conf now looks like the following: service imap-postlogin { executable = script-login /var/www/lighttpd/mail-admin/scripts/lastLogin.sh unix_listener imap-postlogin { user = root } } service imap { executable = imap imap-postlogin } My lastLogin.sh bash script has the following in it for debugging echo "$(date +%Y.%m.%d-%H:%M:%S)"; echo "User: ${USER}" >> /tmp/tracking.log 2>&1; echo "Home: ${HOME}" >> /tmp/tracking.log 2>&1; echo "Client IP: ${IP}" >> /tmp/tracking.log 2>&1; echo "Server IP: ${LOCAL_IP}" >> /tmp/tracking.log 2>&1; The output to my /tmp/tracker.log is the following User: user(a)domain.com Home: /var/spool/mail/domain.com/user Client IP: x.x.x.x Server IP: y.y.y.y The Authentication Error I am getting now dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_mysql.so dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_pgsql.so dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so dovecot: auth: Debug: Read auth token secret from /var/run/dovecot//auth-token-secret.dat dovecot: auth: Debug: auth client connected (pid=25865) dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=imap#011secured#011session=VPOQpNvsPwDELro2#011lip=X.X.X.X#011rip=Y.Y.

[Dovecot] Writing an FTS plugin
by John Morrissey 23 Jan '14

23 Jan '14

Hi, I'm having some trouble writing an FTS plugin that uses notmuch (http://notmuchmail.org/) as the backend. As a proof of concept, I'm adding a hardcoded UID to the search results in the plugin's lookup handler: seq_range_array_add(&result->definite_uids, 1, 42); but this UID is never returned by IMAP SEARCH commands. I know the plugin is being used, since I'm also syslogging immediately before the call to seq_range_array_add(). Interestingly, SEARCH commands return correct results (based on the mailbox content and the search terms specified), but I'm not sure where those results are coming from. The notmuch plugin is the only configured FTS plugin: mail_plugins = $mail_plugins fts fts_notmuch plugin { fts = notmuch } What might I be doing wrong? Additionally, notmuch returns message filenames, which I'll need to translate to UIDs. I've seen maildir_uidlist_get_uid(), but I'm not sure where to get the struct maildir_uidlist arg it needs. notmuch only supports the Maildir format, so using a maildir_* function seems a reasonably safe assumption, but is there a better way? john -- John Morrissey _o /\ ---- __o jwm(a)horde.net _-< \_ / \ ---- < \, www.horde.net/ __(_)/_(_)________/ \_______(_) /_(_)__

[Dovecot] Problem with LDA. When vacation auto-reply sent, the field from=<>.
by Dmitry 23 Jan '14

23 Jan '14

Hi, My problem is that when vacation auto-reply sent the field from=<> Because of this does not work "sender_dependent_relayhost_maps" in postfix. My scheme is: There are several postfix on different machines 1.1.1.1 - domain1 2.2.2.2 - domain2 3.3.3.3 - domain3 All they send messages to one server virtual_transport = lmtp:10.10.10.10:24 where mail is stored. In 10.10.10.10 installed dovecot 2.2.9, dovecot-pigeonhole 0.4.2 and another posfix In postfix inet_interfaces = 10.10.10.10 sender_dependent_relayhost_maps = hash:$config_directory/relayhost_maps relayhost_maps @domain1 [1.1.1.1] @domain2 [2.2.2.2] @domain3 [3.3.3.3] Sieve script make from Roundcube require ["vacation"]; # rule:[autoreply] if true { vacation :days 1 :subject "Test." "Test."; } (if add [":from" string] nothing changes) The letter comes, script fulfills, vacation auto-reply sent. But either /usr/sbin/sendmail -i -f <> -- user@senddomain or, if write in 15-lda.conf submission_host = 10.10.10.10:25 postfix log Jan 1 00:00:00 mail pf-OUT/cleanup[6098]: 4CD104A8A4: message-id=<dovecot-sieve-1390316174-295666-0@mail> Jan 1 00:00:00 mail pf-OUT/qmgr[5950]: 4CD104A8A4: from=<>, size=693, nrcpt=1 (queue active) How to make dovecot and dovecot-pigeonhole write in field MAIL FROM:?

[Dovecot] IDLE dropping EXISTS events on mass message arrival
by Eric Wong 22 Jan '14

22 Jan '14

Hi, I'm not sure if this is some throttling/DoS protection or a bug. I didn't see notice anything like it mentioned looking at the NEWS file from hg, this is on 2.1.7 on Debian stable. I have a client doing IDLE on INBOX.vomiteer. When individual messages arrive with some time interval in between them, I get EXISTS events for each message as expected. However, when I store a bunch of messages at once (via tag + mass copy in mutt on a fast-ish connection), I get a few EXISTS events (sometimes one, sometimes two) even though I copied a lot of new messages over. I expected to get an EXISTS event for each message which arrived, but perhaps there's some sort of DoS/throttling mechanism. strace -t -s4096 output of the dovecot process below: fd=13 is inotify, you'll see large read(13, ... indicating multiple filenames from inotify. However, only one EXISTS message got written to the socket. I've filtered out the gettimeofday syscalls for brevity. 07:30:02 epoll_wait(9, {}, 6, 3937) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/cur", {st_mode=S_IFDIR|0700, st_size=12288, ...}) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/new", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/new", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/cur", {st_mode=S_IFDIR|0700, st_size=12288, ...}) = 0 07:30:06 stat64("/home/ew/.maildir/.INBOX.vomiteer/dovecot.index.log", {st_mode=S_IFREG|0600, st_size=25920, ...}) = 0 07:30:06 fstat64(10, {st_mode=S_IFREG|0600, st_size=25920, ...}) = 0 07:30:06 epoll_wait(9, {}, 6, 7865) = 0 07:30:14 setsockopt(11, SOL_TCP, TCP_CORK, [1], 4) = 0 07:30:14 write(11, "* OK Still here\r\n", 17) = 17 07:30:14 setsockopt(11, SOL_TCP, TCP_CORK, [0], 4) = 0 07:30:14 time(NULL) = 1390289414 07:30:14 epoll_wait(9, {{EPOLLIN, {u32=4159555408, u64=4159555408}}}, 6, 22124) = 1 07:30:17 read(13, "\2\0\0\0\200\0\0\0\t\365\r\0000\0\0\0001390289417.M94623P14841.dcvr,S=1580,W=1619:2,S\0\0\2\0\0\0\200\0\0\0\n\365\r\0000\0\0\0001390289417.M94624P14841.dcvr,S=1580,W=1619:2,S\0\0\2\0\0\0\200\0\0\0\v\365\r\0000\0\0\0001390289417.M94625P14841.dcvr,S=1422,W=1460:2,S\0\0\2\0\0\0\200\0\0\0\f\365\r\0000\0\0\0001390289417.M94626P14841.dcvr,S=1422,W=1460:2,S\0\0\2\0\0\0\200\0\0\0\r\365\r\0000\0\0\0001390289417.M94627P14841.dcvr,S=1861,W=1907:2,S\0\0\2\0\0\0\200\0\0\0\16\365\r\0000\0\0\0001390289417.M94628P14841.dcvr,S=1861,W=1907:2,S\0\0\2\0\0\0\200\0\0\0\17\365\r\0000\0\0\0001390289417.M94629P14841.dcvr,S=4732,W=4854:2,S\0\0\2\0\0\0\200\0\0\0\20\365\r\0000\0\0\0001390289417.M94630P14841.dcvr,S=4732,W=4854:2,S\0\0\2\0\0\0\200\0\0\0\21\365\r\0000\0\0\0001390289417.M94631P14841.dcvr,S=4028,W=4128:2,S\0\0\2\0\0\0\200\0\0\0\22\365\r\0000\0\0\0001390289417.M94632P14841.dcvr,S=4028,W=4128:2,S\0\0\2\0\0\0\200\0\0\0\23\365\r\0000\0\0\0001390289417.M94633P14841.dcvr,S=3865,W=3968:2,S\0\0\2\0\0\0\200\0\0\0\24\365\r\0000\0\0\0001390289417.M94634P14841.dcvr,S=3865,W=3968:2,S\0\0", 32768) = 768 07:30:17 epoll_wait(9, {{EPOLLIN, {u32=4159555408, u64=4159555408}}}, 6, 499) = 1 07:30:17 read(13, "\2\0\0\0\200\0\0\0\25\365\r\0000\0\0\0001390289417.M94635P14841.dcvr,S=4092,W=4189:2,S\0\0\2\0\0\0\200\0\0\0\26\365\r\0000\0\0\0001390289417.M94636P14841.dcvr,S=4092,W=4189:2,S\0\0\2\0\0\0\200\0\0\0\27\365\r\0000\0\0\0001390289417.M94637P14841.dcvr,S=1517,W=1552:2,S\0\0\2\0\0\0\200\0\0\0\30\365\r\0000\0\0\0001390289417.M94638P14841.dcvr,S=1517,W=1552:2,S\0\0", 32768) = 256 07:30:17 epoll_wait(9, {}, 6, 498) = 0 07:30:17 stat64("/home/ew/.maildir/.INBOX.vomiteer/new", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0 07:30:17 stat64("/home/ew/.maildir/.INBOX.vomiteer/cur", {st_mode=S_IFDIR|0700, st_size=12288, ...}) = 0 07:30:17 stat64("/home/ew/.maildir/.INBOX.vomiteer/dovecot.index.log", {st_mode=S_IFREG|0600, st_size=26328, ...}) = 0 07:30:17 fstat64(10, {st_mode=S_IFREG|0600, st_size=26328, ...}) = 0 07:30:17 pread64(10, "\200\200\200\207@\0\0\20\0\0\0\0\0\0\0\0$\0\0\0\0\0\0\0\1\0\0\0\200\200\200\214\0\1\0\20\0\0$\0\337!\336R\344\231\2L\0\0\0\0\t\"\336R\t\"\336R\0\0\0\0\t\"\336R\0\0\0\0007\n\0\0\200\200\200\204 \0\0\20@\0\4\0\234e\0\0\200\200\200\242\2\0\0\20\317\0\0\0\10\0\0\0\320\0\0\0\10\0\0\0\321\0\0\0\10\0\0\0\322\0\0\0\10\0\0\0\323\0\0\0\10\0\0\0\324\0\0\0\10\0\0\0\325\0\0\0\10\0\0\0\326\0\0\0\10\0\0\0\327\0\0\0\10\0\0\0\330\0\0\0\10\0\0\0\331\0\0\0\10\0\0\0\332\0\0\0\10\0\0\0\333\0\0\0\10\0\0\0\334\0\0\0\10\0\0\0\335\0\0\0\10\0\0\0\336\0\0\0\10\0\0\0\200\200\200\207@\0\0\20\1\0\0\0\0\260\2L\0\0\0\0\4\0\4\0\1\0\0\0\200\200\200\242\0\2\0\20\317\0\0\0\250\275\0\0\320\0\0\0\234\277\0\0\321\0\0\0|\301\0\0\322\0\0\0|\304\0\0\323\0\0\0\200\307\0\0\324\0\0\0|\312\0\0\325\0\0\0h\315\0\0\326\0\0\0\\\320\0\0\327\0\0\0\224\323\0\0\330\0\0\0\210\325\0\0\331\0\0\0h\327\0\0\332\0\0\0h\332\0\0\333\0\0\0l\335\0\0\334\0\0\0h\340\0\0\335\0\0\0T\343\0\0\336\0\0\0H\346\0\0\200\200\200\204 \0\0\0200\0\4\0\337\0\0\0", 8192, 25920) = 408 07:30:17 pread64(10, "", 8192, 26328) = 0 07:30:17 stat64("/home/ew/.maildir/.INBOX.vomiteer/dovecot.index.log", {st_mode=S_IFREG|0600, st_size=26328, ...}) = 0 07:30:17 fstat64(10, {st_mode=S_IFREG|0600, st_size=26328, ...}) = 0 07:30:17 time(NULL) = 1390289417 07:30:17 setsockopt(11, SOL_TCP, TCP_CORK, [1], 4) = 0 07:30:17 write(11, "* 32 EXISTS\r\n", 13) = 13 07:30:17 setsockopt(11, SOL_TCP, TCP_CORK, [0], 4) = 0 07:30:17 epoll_wait(9, <unfinished ...> (Nothing happened after this) #
