[Dovecot] Mail filters in incoming message
by Jos Chrispijn 19 Nov '13

19 Nov '13

With my iMap client, I use various mail rules to move specific email to the right mail folders. Downside of that is that is this mailclient is not online, all email is stuck in my inbox, which makes reading email by mobile phone kind of chaotic. I have seen several Pigeonhole Sieve examples, but I would like to know if there is a nub solution (I am not a programmer) to run filters when they enter my mail server (Postfix 2.10.2,1 icw Dovecot 1.2.17) or if there is a user friendly GUI available to set these filters? Perhaps Anyone interested to create such a GUI? Best regards, Jos Chrispijn --- Artificial intelligence is no match for natural stupidity

[Dovecot] wiki links
by Timo Sirainen 19 Nov '13

19 Nov '13

Since google points only to wiki.dovecot.org, I changed it to now redirect all requests to wiki2. I didn’t want to originally do this to avoid breaking all old links, but maybe it’s not that bad anymore. Most links exist anyway for wiki2 too.

[Dovecot] Calling dovecot-lda from maildrop/shell
by Florian Lindner 19 Nov '13

19 Nov '13

Hello, I want to make final delivery for some of my mailboxes using dovecot-lda, since I'm interested in using sieve. My usual MDA which is called from postfix is and will be maildrop. First try was to call dovecot-lda from command line: /usr/lib/dovecot/dovecot-lda -d spam(a)xgm.de < testmail which gave return code 75 (EX_TEMPFAIL) and logged: dovecot: auth-worker(3533): mysql(localhost): Connected to database system dovecot: imap-login: Login: user=<spam(a)xgm.de>, method=PLAIN, rip=::1, lip=::1, mpid=3535, secured, session=<jwXWP3HrwgAAAAAAAAAAAAAAAAAAAAAB> dovecot: imap(spam(a)xgm.de): Disconnected: Logged out in=91 out=830 dovecot: lda(spam(a)xgm.de): Error: user spam(a)xgm.de: Initialization failed: Namespace '': Mail storage autodetection failed with home=/home/flindner/Mail/spam dovecot: lda(spam(a)xgm.de): Fatal: Invalid user settings. Refer to server log for more information. My userdb/password is like that home == maildir == /home/flindner/Mail/spam (without prefixed "maildir:"). It works fine for dovecot-imap, it detects that spam is a maildir. I've also tried prefixing home and or maildir with "maildir:" or calling: HOME=maildir:~/Mail/spam /usr/lib/dovecot/dovecot-lda < testmail which gave: dovecot: lda: Error: user flindner: Relative home directory paths not supported: maildir:/home/flindner/Mail/spam dovecot: lda: Fatal: Invalid user settings. Refer to server log for more information. What is the problem with the LDA here? Thanks, Florian

[Dovecot] Dovecot Listescape plugin problem
by vupibi 18 Nov '13

18 Nov '13

Dovecot Version: 2.0.19 I'm on Ubuntu 12.04.3 using Zentyal with Dovecot for a mail Server. What I try to setup is the possibility to use slashes ("/") in folder names inside the IMAP account. Regularly if I name a folder "foo/bar", the system creates me a folder named "bar" inside a folder named "foo". Listescape should give me the possibility but it does not work. It's not possible for me to write inside the "/etc/dovecot/dovecot.conf" because Zentyal will overwrite all changes when restarting the server. So my Configs are in "/etc/dovecot/extra.conf" and look like this: mail_plugins = listescape (i tried "mail_plugins = $mail_plugins listescape" as well, no success) namespace inbox { separator = "\\" prefix = inbox = yes hidden = no list = yes location = maildir:/var/vmail/%d/%n:LAYOUT=fs } My dovecot -n output # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-55-generic x86_64 Ubuntu 12.04.3 LTS ext4 auth_gssapi_hostname = mailand.sxps.local auth_krb5_keytab = /etc/dovecot/dovecot.keytab auth_mechanisms = gssapi plain first_valid_gid = 116 first_valid_uid = 108 log_timestamp = "%Y-%m-%d %H:%M:%S " mail_gid = 116 mail_home = /var/vmail/sieve/%d/%u mail_location = maildir:/var/vmail/%$ mail_plugins = listescape mail_uid = 108 managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace inbox { hidden = no inbox = yes list = yes location = maildir:/var/vmail/%d/%n:LAYOUT=fs prefix = separator = \ } passdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } plugin { autocreate = Trash autocreate2 = Spam autocreate3 = Sent autocreate4 = Drafts autosubscribe = Trash autosubscribe2 = Spam autosubscribe3 = Sent autosubscribe4 = Drafts quota = maildir:User quota quota_rule = *:storage=0 sieve = /var/vmail/sieve/%d/%u/sieve-script sieve_global_path = /var/vmail/sieve/default.sieve sieve_storage = /var/vmail/sieve/%d/%u } protocols = pop3 imap sieve service auth { executable = /usr/lib/dovecot/auth unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = ebox mode = 0600 user = ebox } user = dovecot } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 } } service managesieve-login { inet_listener sieve { port = 4190 } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 } } ssl_cert = </etc/dovecot/ssl/dovecot.pem ssl_key = </etc/dovecot/ssl/dovecot.pem userdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } protocol imap { mail_plugins = quota imap_quota autocreate } protocol pop3 { mail_plugins = quota } protocol lda { auth_socket_path = /var/run/dovecot/auth-master mail_plugins = sieve quota postmaster_address = admin(a)sxps.eu } Any Ideas? -- View this message in context: http://dovecot.2317879.n4.nabble.com/Dovecot-Listescape-plugin-problem-tp45… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Experience with ALTStorage on NFS mount
by Urban Loesch 18 Nov '13

18 Nov '13

Hi, we are thinking about storing older mails (eg. safed before 6 months) to an alternative storage mounted via NFS from an external storage box. Some technical details - the storage will be connected via 1 gbit ethernet. Access will be allowed from different dovecot servers, but only to divided directories for each dovecot. - storage has the option to use RAID 5 or 6. Max. amount of Disks are 15. - the index files and the primary storage are just divided in two different directories and are stored local on SAS disks with RAID 10 - current mail_location config is: mdbox:/home/vmail/%d/%n:INDEX=/home/dovecotindex/%d/%n - future mail_location config shoudl look like: mdbox:/home/vmail/%d/%n:INDEX=/home/dovecotindex/%d/%n:ALT=/home/extstorage/vmail/%d/%n My question is, if someone of you have already experience in such a setup with NFS? And are there some tuning tips for NFS? We have not many experience with NFS right now. Or perhaps is there some better solution? Many thanks and regards Urban

[Dovecot] I wrote CheckPassword Shell example for Dovecot
by Nicolay Vizovitin 18 Nov '13

18 Nov '13

Hello, Seeing as there are not too many Dovecot CheckPassword driver usage examples on the Internet, I wrote one using Shell script. You can see post about it here: http://devblog.plesk.com/2013/11/shell-checkpassword-authentication-in-dove…. The post also has a link to Mercurial repository with the example. Feel free to use the example as you see fit. You may even include it into documentation (or link to it), if you'd like. Thanks for such great software as Dovecot! -- Best regards, Nick

Anyway I?ve noticed once that 10.9 Mail didn?t show some of my mails until I restarted it. Then there are several other annoying bugs.. I really shouldn?t have upgraded yet. We are running Dovecot 2.0.12, and I already have the Mavericks Mail patch of a few days ago. Still requires a restart to get new mail.

[Dovecot] Issue with Mavericks Mail Client
by Ken Mandelberg 17 Nov '13

17 Nov '13

We run a dovecot mailserver. One of the clients I use is a Mac Laptop. Recently I upgraded from Mountain Lion (10.8) to Mavericks (10.9). Under 10.8 it worked fine. On 10.9 it syncs up when I invoke the client, but after a while stops getting updates. Most of my mail clients are on Linux (thunderbird) or Android (K9) and I admit that several run against my very large INBOX simultaneously. The one of the 10.9 Mac laptop is the only one with this issue. Is there something known about the new 10.9 Mail client on the Mac that would lose sync against dovecot?

[Dovecot] Replication Setup

Hi, I am attempting to setup replication between two hosts running Centos 6.4 and Dovecot 2.2.5. My users are real unix users, so I am trying to run the replication as root user, so that it has the appropriate permissions to run. I have two users at present syd1 and syd2, and the two hosts are called syd1 and syd2 as well. When I start Dovecot with the settings below, nothing happens, and the two mailboxes remain un-synced. There are no errors in the log, just Dovecot starting successfully. I have attempted to run the dsync command manually from syd1: ssh -q -o StrictHostKeyChecking=no -i /home/vmail/.ssh/id_ecdsa root@syd2 doveadm dsync-server -usyd1 and I get the following in response, but this might be normal: VERSION dsync 3 1 Hhostname sync_ns_prefix sync_box sync_box_guid sync_type debug sync_visible_namespaces exclude_mailboxes send_mail_requests backup_send backup_recv lock_timeouno_mail_sync no_backup_overwrite Smailbox_guid last_uidvalidity last_common_uid last_common_modseq last_common_pvt_modseq changes_during_sync Nname existence mailbox_guid uid_validity uid_next last_renamed_or_created subscribed last_subscription_change Dhierarchy_sep mailboxes dirs unsubscribes Bmailbox_guid uid_validity uid_next messages_count first_recent_uid highest_modseq highest_pvt_modseq mailbox_lost cache_fields have_guids have_save_guids Atype key value stream deleted last_change modseq Ctype uid guid hdr_hash modseq pvt_modseq save_timestamp add_flags remove_flags final_flags keywords_reset keyword_changes Rguid uid Mguid uid pop3_uidl pop3_order received_date stream cname decision last_used .

[Dovecot] Dovecot antispam unable to call dspam since dovecot upgrade to 2.X
by Guillaume Hilt 15 Nov '13

Hello, Running Gentoo AMD64 2013 with postfix, mysql, dovecot and dspam, i finally upgraded to dovecot 2.X. I'm running dovecot 2.2.6, dspam 3.10.2-r1 and dovecot-antispam-2.0_pre20130429. My DSPAM configuration hasn't changed between dovecot 1.X and 2.X.

[Dovecot] Sieve script problem (don't know if is it possible to do this)
by Yanko Hernández Álvarez 15 Nov '13

15 Nov '13

Hello: I'm loosing my mind trying to classify my outgoing messages with sieve-test (2.0.9, centos 6.4). It came to the point I think it's not even possible with a sieve script. I need to classify my outgoing messages in three folders: 1- To my department (@dept.example.com) 2- To my company (@example.com, @anyotherdept.example.com) (anyotherdept.example.com as in a way to say "any other domain that ends with 'example.com', but not 'dept.example.com'") 3- To the rest of the word (@any.other.domain) The problematic requirement is I need to make a copy in EVERY IMAP folder that applies. For instance: for an email such as ---- From: myuser(a)dept.example.com To: user(a)dept.example.com, user(a)example.com, user(a)other.domain ... ---- I need to make a copy to all folders: Dept (because of user(a)dept.example.com) Company (because of user(a)example.com) and Rest (because of user(a)other.domain) Rule for #1 is simple: ----- if address :matches :domain "To" "dept.example.com" { fileinto: "Dept"; } ----- Rule for #2, I don't know how to declare it: I don't know how to make a rule that matches "example.com" (or anyotherdept.example.com) and not "dept.example.com". if allof(address :matches :domain "To" "example.com", not address :matches :domain "To" "dept.example.com") { fileinto: "Company"; } ... doesn't work, because user(a)dept.example.com matches (address :matches :domain "To" "example.com"), but it doesn't matches (not address :matches :domain "To" "dept.example.com"). "user(a)example.com" matches both conditions, but sieve-test stops on the first email address with a "not matches" As for Rule #3: I don't know how to do it either, it should be the same as Rule #2, (with different parameters of course). A sieve script should be capable to do this, but it seems that I'm loosing something. Does any one knows how to do this? Kind regards Yanko PS: English is not my native language. Please forgive me any mistakes/misspellings/etc I made.

[Dovecot] Fwd: Sieve script problem (don't know if is it possible to do this)
by Yanko Hernández Álvarez 15 Nov '13

15 Nov '13

Ok, let simplify a little bit the problem: Forget about outgoing or incoming mail. Forget about IMAP or SMTP. You have a ton of emails in raw form (RFC-XXX, don’t remember the exact number right now) you want to classify… and you think: “Sieve is a language made to do exactly that kind of task… If only I could use the same mechanism dovecot-lda uses! Oh, wait… “sieve-test –e” does exactly that!!! I could use it!!!”… but so far… no success. Now, a little more context. I want to leave a copy (a historical record) of every email (work related) I received/sent. The processing/classification doesn’t have to be in real time, it can be on “down time/offline/later/scheduled”. Sent messages are hard, because of the several senders and the several copies on several folders. But I can work around it, with various tricks (bcc, different headers, etc.) and adjusting the processing sieve script. I can train myself –The interest is mine after all!-, and that’s OK. But I can’t train other people to suit my needs. And received messages are JUST AS HARD. Because I want to classify them using the same rules. I also want to keep context, to record all things work related, not only what I said, but also what was said by others, using the same rules (which by the way, are many more than the restricted example I posted). Besides, I want the PC do all the work for me, not the other way around. I think “Sieve must be capable of doing it! This is the kind of things sieve was designed for!” is a reasonable idea. But so far, no success… :-( Now, let me see all the replies in detail...

[Dovecot] Establing a GMail like workflow
by Florian Lindner 15 Nov '13

15 Nov '13

Hello! I'm about to migrate my mails from GMail back to my self hosted solution, using Dovecot imap server. I really liked gmail workflow: - (Almost) all mail goes to inbox. - Most mail is read and not important anymore, it is archived and moved to "all messages". - Inbox stays more or less clean, with only mails that are still of some interest. - Mail (except Spam) is never deleted, just archived. How can I achieve such a workflow using Dovecot and some MUA (Roundcube and probably KMail). - I can simply delete messages that I want to archive, Trash will never be purged. Problems: Some mail clients have settings like "Purge Trash at exit", so my mail is always in danger of being deleted accidently. Futhermore it does not really have the semantics of what I am actually doing. - Instead of deleting messages for archiving, move them to some Archiv folder. Since archiving is a very frequent action this involves much more cliks in the MUA than just deleting. Or some configuration change in the client. How would you do that? I'm also open to entirely different suggestions! What I want are basically these things: - Never delete legitimate mail - Use the Inbox as a workspace for mails that are still of some interest. This can also be quite old mail, time based archiving does not work. - Have some kind of mail archive. Thanks! Florian

[Dovecot] Dovecot login slow
by Marc Perkel 15 Nov '13

15 Nov '13

Can't figure out why the login is slow. I telnet to port 143 on localhost. I type: 0 login user password Takes about 10 seconds and it lets me in. I'm using MYSQL and it's a small indexed database on a fast server so it's not the mysql query that's slowing it down. At least I don't think it is. But - kind of stumped. Just wondering if there's something obvious I'm overlooking.

[Dovecot] Executing a wget? or clicking on a link in inbound email?
by Voytek 14 Nov '13

14 Nov '13

I use Dovecot, but all I know about Dovecot is that's it is an IMAP server, and, I know that it includes lots of other stuff that I see discussed on this list, but I know nothing about it. I have a situation that, maybe once a week, I get an html only email that contains 3 clickable links. I would like, on receipt of such email, auto click the first link (perhaps execute a wget to do so? or ?) Can something like this be done, which of the tools, what docs to look at? link is like so http://llll.domain.tld/irportal?id=a0000000006hWO4AAM0000000000KlOrcAAF1111… Dovecot 2.09 Centos (apologies for blank post I've just sent) -- Sent from Kaiten Mail.

[Dovecot] Autocreation of sieve filters
by Angel L. Mateo 14 Nov '13

14 Nov '13

Hello, Is there any way to create a predefined sieve filters during mailbox autocreation? What I want is that my user's mailboxes are automatically created (using mailbox option in namespaces) but I want them to have a predefined sieve script. Using a postlogin script could be an idea, but I'd prefer an automatic one, because postlogin only will filter after first user login -- Angel L.

[Dovecot] Dovecot 2.0.9 Quota Limit issues
by David Johnson 14 Nov '13

14 Nov '13

Hello, I've tried searching for information regarding this problem but haven't found anything. Currently I have a Dovecot 2.0.9 with virtual users from a SQL table. Right now I'm only using global quota limits. Here is my quota setup: plugin { quota = maildir:User quota quota_rule = *:storage=3G quota_rule2 = Trash:storage=+100M quota_rule3 = Archive:storage=+1G quota_rule4 = Archive/2013:storage=+1G quota_rule5 = Junk:ignore } According to the documentation this should allow the Archive folder to have an additional 1G in it that is not counted toward the global 3G. However I have users who have 2G in the Archive folder, and about 1G elsewhere. At this point they stop receiving emails due to quota exceeded. doveadm quota get -u <user> displays this: Quota name Type Value Limit % User quota STORAGE 3150312 3145728 100 User quota MESSAGE 8271 - 0 If I change Archive:storage=+1G to Archive:ignore then they can receive emails again. After the change doveadm quota get -u displays this: Quota name Type Value Limit % User quota STORAGE 1266885 3145728 40 User quota MESSAGE 8271 - 0 Is there something I'm missing as to why this setup isn't working? Thanks! -- David J.

[Dovecot] Can't see e-mails

12 Nov '13

Hi, I have a postfix+dovecot+mysql+roundcube setup. I recently changed providers. At the moment, postfix can receive e-mails but either dovecot or roundcube can't see e-mails. I did a telnet example.com 143 then a login user pass and this is what I see: 2013-11-12 16:08:51 auth: Debug: sql(alanya(a)boradental.com.tr,193.255.135.254): SELE CT '/var/vmail/boradental.com.tr/alanya' as home, 'maildir:/var/vmail/ boradental.com .tr/alanya' as mail, 5000 AS uid, 5000 AS gid, concat('dirsize:storage=', quota) AS quota FROM mailbox WHERE username = 'alanya(a)boradental.com.tr' AND active = '1' 2013-11-12 16:08:51 auth: Debug: master out: USER 3767009281 alanya@borad ental.com.tr home=/var/vmail/boradental.com.tr/alanya mail=maildir:/va r/vmail/boradental.com.tr/alanya uid=5000 gid=5000 quota=dirsize:storage=0 so I'm assuming dovecot works.

[Dovecot] Dovecot MTA
by Timo Sirainen 12 Nov '13

12 Nov '13

Hi all, I've never really wanted to create my own MTA, because I like Postfix quite a lot. And I always thought it would require a horribly lot of time to be able to create something that was anywhere even close to having Postfix's features. (I would shudder to even think about recreating Dovecot from scratch nowadays.) But slowly over time I've also been thinking of ways how things could be done a bit better, and I think I have enough ideas to start thinking about Dovecot MTA more seriously in a few more months (after my current busy schedule calms down a bit). And (unlike Dovecot!) I'm not planning on taking over the world with the MTA (or at least not very quickly), but it would definitely be useful for many installations I know of. My main design goals for the MTA are: * In normal load don't queue mails, just continue delivering the mail through different processes/services until it succeeds or fails, and only after that return ok/failure to the SMTP client. So there's no (forced) post-queue filtering, everything would normally happen pre-queue. This is required because in Germany (and EU in general?) you aren't allowed to just drop spams after SMTP server has responsed OK to the client, even if you’re 100% sure it’s a spam. So this would also mean that the SMTP DATA replies will come more slowly, which means that the SMTP server must be able to handle a lot more concurrent SMTP connections, which means that in large installations the smtpd process must be able to asynchronously handle multiple SMTP client connections. * In some cases you can't really avoid placing mails into a queue. This could be because of temporary failures or maybe because of an abnormal load spike. A mail queue in local disk isn't very nice though, because if the local disk dies, the queued mails are lost. Dovecot MTA will allow the queue to be in object storage and it will also likely support replication (similar to current dsync replication). In both of these cases if a server dies, another server can quickly take over its queue and continue handling it. * Dovecot MTA is a new product, which means we can add some requirements to how it's being used, especially related to securely sending emails between servers. It could do a bunch of checks at startup and fail to even start if everything isn't correct. Here are some things I had in mind - not sure if all of these are good ideas or not: - Require DKIM configuration. All outgoing mails will be DKIM signed. - Require the domain’s DNS to contain _submission._tcp SRV record (and actually might as well require _imap._tcp too) - Require SSL certificates to be configured and always allow remote to use STARTTLS - Require DANE TLSA record to exist and match the server's configured SSL cert - Have very good (and strict?) DNSSEC support. If we know a remote server is supposed to have valid DNSSEC entries, but doesn't, fail to deliver mail entirely? - Add a new DNS record that advertises this is a Dovecot MTA (or compatible). If such entry is found (especially when correctness is guaranteed by DNSSEC), the email sender can assume that certain features exist and work correctly. If they don't, it could indicate an attack and the mail sending should be retried later. This DNS record would of course be good to try to standardize. * Configuration: It would take years to implement all of the settings that Postfix has, but I think it's not going to be necessary. In fact I think the number of new settings to dovecot.conf that Dovecot MTA requires would be very minimal. Instead nearly all of the configuration could be done using Sieve scripts. We'd need to implement some new MTA-specific Sieve extensions and a few core features/configurations/databases that the scripts can use, but after that there wouldn't be really any limits to what could be done with them. * Try to implement as many existing interfaces as possible (e.g. Milter and various Postfix APIs like policy servers) so that it wouldn’t be necessary to reimplement all the tools and filters. So perhaps something like this could be done in time for Dovecot v2.4. Any thoughts/ideas/suggestions?

[Dovecot] Getting debug output from antispam plugin with dspam
by Igor Zinovik 11 Nov '13

11 Nov '13

Hello. I'm trying to get some output from antispam plugin when it invokes dspam binary for retraining. Currently I see no messages related to dspam execution. Dovecot IMAP server works as 'vmail' user: # ps aux|grep 'dovecot/imap' vmail 3062 0.7 0.0 29824 3008 ? S 16:22 0:00 dovecot/imap User 'vmail' is listed as trusted in /etc/dspam/dspam.conf # fgrep vmail /etc/dspam/dspam.conf Trust vmail Dovecot IMAP plugins and antispam configuration: # doveconf -n | egrep -e '(^#|antispam|protocol imap)' # 2.2.7: /etc/dovecot/dovecot.conf # OS: Linux 3.7.10-1.16-default x86_64 openSUSE 12.3 (x86_64) antispam_allow_append_to_spam = YES antispam_backend = dspam antispam_dspam_args = --client;--user;%Lu;--deliver=spam,innocent;--source=error;--signature=%%s antispam_dspam_binary = /usr/sbin/dspam antispam_dspam_notspam = --class=innocent antispam_dspam_result_header = X-DSPAM-Result antispam_dspam_spam = --class=spam antispam_signature = X-DSPAM-Signature antispam_signature_missing = move antispam_spam = Spam antispam_trash = trash;Trash;Deleted;deleted;Deleted Items protocol imap { mail_plugins = expire mail_log notify quota trash imap_quota antispam Antispam plugin is successfully loaded: # grep antispam_plugin /var/log/dovecot/dovecot.log Nov 11 16:22:32 imap: Debug: Module loaded: /usr/lib64/dovecot/modules/lib90_antispam_plugin.so As i understand plugin would not work with message that do not contains dspam signature, so I sent GTUBE message to myself and when I move it to Spam folder I see only Dovecot messages: Nov 11 16:28:06 imap(zinovik(a)example.org): Info: copy from INBOX: box=Spam, uid=3422, msgid=<20131111144014.731f035b871deb0e082bc22e(a)example.org>, size=1130 Nov 11 16:28:06 imap(zinovik(a)example.org): Info: delete: box=INBOX, uid=26792, msgid=<20131111144014.731f035b871deb0e082bc22e(a)example.org>, size=1130 Nov 11 16:28:06 imap(zinovik(a)example.org): Info: expunge: box=INBOX, uid=26792, msgid=<20131111144014.731f035b871deb0e082bc22e(a)example.org>, size=1130 Dspam logs nothing, though debugging is turned on # ps aux | egrep -e '^dspam' dspam 2939 0.0 0.0 116408 2420 ?

The bug is related to the sieve module in /src/lib-sieve/plugins/notify/ext-notify-common.c:266. The line contains only a check if mail_get_headers_utf8 returns an error. So the workaround for this line would be to add a check if header[0] is not NULL. if ( (mail_get_headers_utf8(msgdata->mail, "subject", &header) >= 0) && header[0] ) str_append(out_msg, header[0]); IMHO this patch should be applied to the "$from$" replacement as well. The comments in the dovecot's header file says for mail_get_headers: Returns -1 if error, 0 otherwise (with or without headers found). hope it helps, Regards Christian Ferbar

[Dovecot] Question about folder sharing
by Achim Gottinger 09 Nov '13

09 Nov '13

Hi, I run dovecot (2.1.7) on debian wheezy in conjuniction with postfix, samba4 (as ldap backend) and sogo. I configured folder sharing but have an few issues. With my current config users can share the inbox and other folders. If the acl allows creatings subfolders this does work for all folders beside inbox. What i want to archiev is the following: If an user shares his inbox, others should be able to create subfolders and those should inherit the inboxe's acl. All subfolders of inbox should appear as folders at root level and not as subfolders of the inbox. I thought this can be done by setting the prefix of namespace inbox to INBOX/. I did this and changed the IMAP Server Folder setting in thunderbird to INBOX (like it was earlier when i used courier). Now subfolders created at rootlevel or as subfolders of the inbox appear on rootlevel in thunderbird but they do not inherit the acl's from inbox. Is there an way to achive this? doveconf -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.2 ext4 auth_debug = yes auth_gssapi_hostname = $ALL auth_krb5_keytab = /etc/dovecot/dovecot.keytab auth_master_user_separator = % auth_mechanisms = plain login gssapi auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@% auth_username_format = %n auth_verbose = yes debug_log_path = syslog disable_plaintext_auth = no first_valid_gid = 998 first_valid_uid = 998 info_log_path = syslog mail_debug = yes mail_gid = 998 mail_home = /home/vmail/%u mail_location = maildir:/home/vmail/%u/mail mail_plugins = acl mail_shared_explicit_inbox = no mail_uid = 998 maildir_very_dirty_syncs = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace { list = children location = maildir:/home/vmail/%%u/mail:INDEX=/home/vmail/%u/mail/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = maildir:/home/vmail/%u/mail prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-ldap-passdb.conf.ext driver = ldap } passdb { args = /etc/dovecot/passwd.masterusers driver = passwd-file master = yes } plugin { acl = vfile acl_anyone = allow acl_shared_dict = file:/home/vmail/.shared-mailboxes sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap lmtp sieve" service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = vmail mode = 0777 user = vmail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } service imap-postlogin { executable = script-login /etc/dovecot/acl-groups.sh user = $default_internal_user } service imap { executable = imap imap-postlogin } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0666 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } } ssl_cert = </etc/easy-rsa/keys/dovecot.crt ssl_key = </etc/easy-rsa/keys/dovecot.key userdb { args = /etc/dovecot/dovecot-ldap-userdb.conf.ext driver = ldap } userdb { args = /etc/dovecot/dovecot-ldap-userdb-groups.conf.ext driver = ldap } protocol imap { imap_client_workarounds = delay-newmail mail_plugins = acl imap_acl } protocol lmtp { mail_plugins = acl sieve }

[Dovecot] how to calculate mail storage/traffic used
by Götz Reinicke - IT Koordinator 08 Nov '13

08 Nov '13

Hi, may be som mailserver admins on the list can give me som hint. Thats not dovecot related, but I know the knowledg here is enormous. We have to setup a server which gets a copy of all messages send and received by our mailserver as a 1:1 copy. Mails send to multiple recipients should be calculated and saved per user. (great if you usually have lost of mails send to groups of people.) So no dedublication should be used here. (e.g. save the message and refer the different recipients to it.) How can I calculate the current traffic in the best way to extrapolate the amount of space to be planed for the new server? We think to have a couples of days to be saved. Thanks for any hint or comment.

[Dovecot] Solr clusters
by Timo Sirainen 07 Nov '13

07 Nov '13

Hi all, Has anyone implemented larger Dovecot+Solr clusters and would be willing to give some details about how it works for you? My understanding about it so far is: - SolrCloud isn’t usable with Dovecot. Replication isn’t useful, because nobody wants to pay for double the disk space for indexes that could be regenerated anyway. The autosharding isn’t very useful also, because: I think the shard keys could be created in two possible ways: a) Mails would be entirely randomly distributed across the cluster. This would make updates efficient, because the writes would be fully distributed across all servers. But I think it would also make reads somewhat inefficient, since all the servers would have to be searched and the results combined. Also if a server is lost, there’s no easy way to reindex back the missing data, because it would contain a piece of pretty much all the users’ data. b) Shard keys could be created so that the same user would typically go only to 1-2 servers. It would be possible (at least in theory) to find a broken server’s list of users and reindex only their data, but I’m not sure if this method is any easier than the non-SolrCloud setup. - Without SolrCloud you’d then need to shard the data manually. This would be easy enough to do by just assigning different users to different shards. But at some point the index is going to become too large and you need to add more shards and move some existing users to them. To keep the search performance good during the move, I guess this could be done with a script that does: 1) reindex user to new shard, 2) update userdb to point to new shard, 3) delete user from old shard, 4) doveadm fts rescan the user to remove any mails already deleted during the reindexing. - It seems that Solr index shouldn’t grow above 200 GB or the performance will be getting too bad? I’ve seen this in a few web pages. So each server should likely be running multiple separate Solr instances (shards). - http://www.hathitrust.org/blogs/large-scale-search/scaling-large-scale-sear… recommends NFS (or I guess any kind of a shared filesystem), which does seem to make sense. Since Dovecot wants to get instantly updated search results after indexing, I think it’s probably better not to separate the indexing and searching servers. - Would be interesting to know what kind of hardware your Solr servers currently have, how well they’re performing and what are the bottlenecks? From the above URL it appears that disk I/O is first, but if there’s enough of that available then CPU usage is second. I’m not quite sure where most of the memory goes - caching? - I’m guessing users are doing relatively few searches compared to how many new emails are being indexed/deleted all the time?

[Dovecot] Postfix delivers mails to maildir and not to dovecot LDA for a virtual user
by Tru Pheenix 06 Nov '13

06 Nov '13

Hi I have been able to setup postfix and dovecot using postgres as the backend store with virtual user maps on Ubuntu 12.04 LTS Server. I have been following instructions from here: http://wiki2.dovecot.org/HowTo/DovecotPostgresql I haven't setup postfix to use saslauthd and PAM, instead I am using dovecot for SASL authentication. Rest of the table structures and query files are the same as from the wiki. SASL authentication works correctly for SMTP POP IMAP. I am able to send emails from a mail client such as Thunderbird with SASL authentication. However I am not able to receive emails for virtual users. I cannot figure out why. System users are getting their emails in the mail box correctly. Postfix fires the mailbox_command to hand over the mail to dovecot. This is how my *mail.log* looks when I send emails from an external domain: Nov 6 06:48:21 localhost postfix/smtpd[20053]: E075280C52: client= mail-ee0-f41.google.com[74.125.83.41] Nov 6 06:48:22 localhost postfix/cleanup[20064]: E075280C52: message-id=< CAJ+V0eCU891rSzSMVbcSy4zsRUk5GUp58b70Wv_WgZxLbKuyLw(a)mail.gmail.com> Nov 6 06:48:22 localhost postfix/qmgr[17492]: E075280C52: from=< me(a)gmail.com>, size=3124, nrcpt=1 (queue active) *Nov 6 06:48:22 localhost postfix/virtual[20066]: E075280C52: to=<someone(a)mydomain.com <someone(a)mydomain.com>>, relay=virtual, delay=0.85, delays=0.7/0.02/0/0.13, dsn=2.0.0, status=sent (delivered to maildir)* Nov 6 06:48:22 localhost postfix/qmgr[17492]: E075280C52: removed Nov 6 06:48:22 localhost postfix/smtpd[20053]: disconnect from mail-ee0-f41.google.com[74.125.83.41] Postfix seems to deliver the mail to maildir instead of the home directory of the virtual user.

[Dovecot] Missing i_stream_unref in imap_msgpart_crlf_seek()?
by Tomasz Potega 06 Nov '13

06 Nov '13

Hi, imap_msgpart_crlf_seek() returns an error stream in case of problems in message_skip_virtual(). The original input stream is not being unreferenced, preventing destroy callbacks from being executed. Shouldn't we have an i_stream_unref(&input) here: src/lib-imap-storage/imap-msgpart.c: 398 if (message_skip_virtual(input, virtual_skip, &cr_skipped) < 0) { 399 errinput = i_stream_create_error(errno); 400 i_stream_set_name(errinput, i_stream_get_name(input)); 401 return errinput; 402 } ?

[Dovecot] 2.2.6 auth process crash using LMTP and LDAP on director.
by Olivier Girard 06 Nov '13

06 Nov '13

I'm upgrading my configuration to use director and lmtp for delivery. (doveconf -n at end of the mail). I use the same config for auth on mail backends and see no errors. My setup seem to work nicely but i have some auth process crashing when using lmtp protocol. Everything is working a sexpected then i've got 5-6 errors like this in logs and a crach of the auth process: dovecot: lmtp(47269): Error: passdb lookup(_mail_): Disconnected unexpectedly pid 47406 (auth), uid 143: exited on signal 11 Actually, i didn't configure to core dump. Do you think seting up lmtp protocol to static auth adding something like folow will be better for this problem? protocol lmtp { passdb { args = proxy=y nopassword=y driver = static } } Please note that my configuration is actually listening on inet fot LMTP but that the goal is to configure postfix on the same server and switch to socket, this expain the configuration of the service auth to provide a socket to postfix. Here is my director config: % doveconf -n # 2.2.6: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.4-RELEASE-p4 amd64 auth_cache_negative_ttl = 0 auth_cache_size = 16 M auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = sha1 default_process_limit = 4000 director_mail_servers = 192.168.16.1 192.168.16.2 192.168.16.3 director_servers = 192.168.16.4 192.168.16.5 192.168.16.6 disable_plaintext_auth = no doveadm_port = 24245 info_log_path = syslog instance_name = director lmtp_proxy = yes mail_debug = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size } service anvil { client_limit = 12003 } service auth-worker { process_min_avail = 10 user = $default_internal_user } service auth { client_limit = 16000 unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { mode = 0666 user = $default_internal_user } user = $default_internal_user } service director { fifo_listener login/proxy-notify { mode = 0666 } inet_listener { address = 192.168.16.4 port = 9090 } unix_listener director-userdb { mode = 0600 } unix_listener login/director { mode = 0666 } } service doveadm { inet_listener { port = 24245 } } service imap-login { executable = imap-login director } service lmtp { inet_listener lmtp { address = * :: port = 24 } } service pop3-login { executable = pop3-login director } ssl_cert = </etc/ssl/cert/mail.univ-angers.fr.pem ssl_key = </etc/ssl/cert/mail.univ-angers.fr.key userdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { auth_socket_path = director-userdb } protocol doveadm { auth_socket_path = director-userdb } local 192.168.16.0/24/24 { doveadm_password = mysecret } Last thing, in my config file, there is only one /24 on local network but this is another problem.
